The benefits of low-dose colchicine (Colcrys) are consistent if started months or years after acute coronary syndrome (ACS) in patients with stable coronary artery disease, a new LoDoCo2 subanalysis suggests.

As previously reported, the parent trial showed that adding colchicine 0.5 mg daily to standard care reduced the risk of the primary endpoint – a composite of cardiovascular (CV) death, myocardial infarction (MI), ischemic stroke, or ischemia-driven coronary revascularization – by 31% compared with placebo.

In the new analysis, led by Tjerk S.J. Opstal, MD, the anti-inflammatory agent was equally effective in reducing the risk of the primary endpoint in patients with no prior ACS, a recent ACS (6-24 months), remote ACS (2-7 years), or very remote ACS (> 7 years), with no interaction found between groups (P = .59).

The incidence of the primary endpoint per 100 person-years and hazard ratios (HRs) for the four groups with colchicine and placebo are as follows:

• No prior ACS: 2.8 vs. 3.4; HR, 0.81 (95% confidence interval, 0.52-1.27).
• Recent ACS: 2.4 vs. 3.3; HR, 0.75 (95% CI, 0.51-1.10).
• Remote ACS: 1.8 vs. 3.2; HR, 0.55 (95% CI, 0.37-0.82)
• Very remote ACS: 3.0 vs. 4.3; HR, 0.70 (95% CI, 0.51-0.96).

The results were reported Aug. 23 in the Journal of the American College of Cardiology.

In contrast, however, a recent subgroup analysis from the COLCOT trial reported an even greater reduction in its primary composite CV endpoint when colchicine was started within 3 days of an MI.

“The result of COLCOT could imply that initiation of colchicine treatment would be best suited directly after myocardial infarction,” Dr. Opstal, from Radboud University Medical Center, Nijmegen, the Netherlands, said in an interview. “Our subanalysis shows that later initiation of colchicine therapy in patients visiting outpatient clinics years after their ACS events is equally effective. As such, colchicine therapy should not be limited to patients with recent ACS, and should be considered in all patients with coronary artery disease.”

Dr. Opstal pointed out that the two trials targeted different populations. COLCOT enrolled 4,765 patients within a month of MI, whereas LoDoCo2 enrolled 5,522 patients who were clinically stable for at least 6 months after an ACS or coronary revascularization.

Overall, 864 LoDoCo2 patients had no prior ACS and 86% had a history of ACS, of which 1,479 were recent, 1,582 were remote, and 1,597 were very remote.

Patients with a history of very remote ACS had a numerically higher event rate for the primary outcome, but the difference was not statistically significant and could be attributed to a play of chance, noted Dr. Opstal.

The team presumed patients with more recent prior ACS would remain at higher risk of ACS recurrence than would those with a more remote ACS that had proved to be clinically stable under standard medical therapy. But, he said, the data show they were at equal risk of the primary outcome.

“This implies that current optimal medical therapy does not result in an attenuation of residual risk over time regardless of whether patients are clinically stable, and that the ongoing process of atherosclerosis results in continuously elevated risk, which warrants new avenues of therapy, such as anti-inflammatory medication,” Dr. Opstal said.

In a binary analysis, there was no difference in composite cardiovascular events between patients with and without prior ACS (HR, 0.67 vs. HR, 0.81; P value for interaction, 0.43).

Dr. Opstal observed that a lack of statistical power precludes any definitive conclusions and that a large randomized controlled trial in patients with established coronary artery disease (CAD) but no prior ACS would elucidate whether early initiation of colchicine is “warranted at the moment CAD is established but before a first ACS event, as is common practice with acetylsalicylic acid and statins.”

In addition, the ongoing OASIS 9 trial will answer the question of whether patients with an estimated glomerular filtration rate of 30-60 mL/min can safely use low-dose colchicine. The gout medication is contraindicated in patients with severe renal or hepatic impairment and in patients on drugs that inhibit both CYP3A4 or the P-glycoprotein.

In an accompanying editorial, colchicine researchers Jean-Claude Tardif, MD, and Guillaume Marquis-Gravel, MD, of the Montreal Heart Institute, Quebec, Canada, suggest that study design features likely explain the discord between the LoDoCo2 and COLCOT subgroup analyses and the lack of difference in CV event rates between patients with and without prior ACS.

The editorialists say lingering questions remain, including the value of colchicine in patients with diabetes or peripheral artery disease without known CAD, but they also point out that three 2021 meta-analyses confirmed large reductions in the risk of CV events, MI, and coronary revascularization with low-dose colchicine.

“In light of the positive results from LoDoCo2, COLCOT, and meta-analyses; its good tolerability profile; and cost-effectiveness, inflammation reduction with low-dose colchicine should be considered to treat patients with coronary disease in the absence of severe renal dysfunction,” Dr. Tardif and Dr. Marquis-Gravel concluded.

The study was supported by the National Health Medical Research Council of Australia; a grant from the Sir Charles Gairdner Research Advisory Committee; the Withering Foundation; the Netherlands Heart Foundation; the Netherlands Organization for Health Research and Development; and a consortium of Teva, Disphar, and Tiofarma in the Netherlands.

There will be so much more to the annual congress of the European Society of Cardiology, which begins Aug. 27 with an all-virtual format, than detailed primary results of EMPEROR-Preserved, a trial that could mark a turning point for heart failure (HF) medical therapy.

Also among the featured Hot Line and Late-Breaking Science sessions are – along with many other studies – explorations of arrhythmia management (ablation or guided by loop recorder); secondary prevention, including by vaccination; oral anticoagulation, notably after transcatheter valve procedures; and colchicine or thrombosis prophylaxis in hospitalized patients with COVID-19.

There will even be a head-to-head comparison of two long-familiar left atrial appendage (LAA) occluders, and a population-based, randomized trial of sodium restriction through wide-scale use of a potassium-based salt substitute.

The congress will also introduce four guideline documents at sessions throughout the Congress, one on each day. They cover new and modified recommendations for heart failure; pacing, including cardiac resynchronization therapy (CRT); cardiovascular (CV) disease prevention; and, with cosponsorship from the European Association for Cardio-Thoracic Surgery, valvular heart disease.
 

The virtues of virtual

That next year’s Congress is slated for Aug. 27-30 in Barcelona should be welcome news for anyone whose “what if” curiosity about all-virtual conferences has already been satisfied. But with experience comes wisdom, as the medical societies have learned that online scientific meetings have some winning qualities that may be worth keeping, as least for a while.

“I think there is no doubt that the digital format will continue, for several reasons. One is that this pandemic is not over,” ESC Congress program committee chair Stephan Windecker, MD, Bern (Switzerland) University Hospital, , told this news organization. “As long as it is not over, the digital format is here to stay.”

But it also appears that people who haven’t been able to attend the congress in person are keen to log in and engage online, Dr. Windecker said. The 2020 all-virtual conference drew a much younger pool of registrants, on average, than did the live conferences before the pandemic.

“I think that’s an indication of people that may be in training, in early stages of their career, or they don’t have the support from departments or from their practice, or other financial means.” But they are able to participate via computer, tablet, or smartphone, he said.

“Another advantage is that the recorded content can be replayed at the convenience of whoever wants to consume it at a later point in time,” he added. “Those are just some examples why the digital format is likely to stay,” on its own or in a new age of hybrid meetings.  
 

New and updated guidelines

Leading off the guideline series is the document on diagnosis and treatment of acute and chronic HF, which leveraged the past few busy years of HF clinical trials to arrive at a number of new recommendations and strengthened level-of-evidence ratings. It covers both drug and device therapy of HF with reduced ejection fraction (HFrEF) and acute decompensated HF, and tweaks and further enshrines the concept of HF with mildly reduced ejection fraction (HFmrEF).

Several updated recommendations for both long-used and novel medications, notably the sodium-glucose cotransporter 2 inhibitors, will be included because of the recently appreciated evidence-based impact in HFrEF, Dr. Windecker noted.

“I think it will be particularly interesting to look for the SGLT2 inhibitors as not a completely new class of drugs, but certainly one where there has been a lot of new evidence, to look at how those drugs will be integrated in the overall care pathway.”

A top-line preview of the new HF guideline limited to drug therapy, presented at July’s Heart Failure Association of the European Society of Cardiology (ESC-HFA), provided a simple answer to a common question in the new, bountiful age of HFrEF medications: Which meds, initiated in what order?

As it happens, the new recommendation for first-line HFrEF drug therapy is not a silver bullet, but a shotgun – prompt initiation of at least four meds, one from each of four drug classes: renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRA), and SGLT2 inhibitors. Each class, as described in the document, is to be started as soon as safely feasible, in a sequence deemed appropriate for each individual patient.
 

Spotlight on EMPEROR-Preserved

The world already knows that the trial, which tested the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) on top of standard therapy, “met” its primary endpoint in almost 6,000 patients with HF with preserved ejection fraction (HFpEF), who included some with HFmrEF by more contemporary definitions.

That means patients in EMPEROR-Preserved assigned to take empagliflozin showed significantly fewer events that made up the study’s primary endpoint, a composite of CV death or HF hospitalization. It appears to be the first clearly significant overall medical therapy benefit for a clinical primary endpoint in a major randomized HFpEF drug trial.

And that, pending fuller presentation of trial results at the Congress on Aug. 27, could be a huge deal for the half of HF patients with left ventricular ejection fractions (LVEF) higher than the HFrEF range.

Those early top-line results weren’t a decisive bombshell for a field now filled with hope for a practice-changing empagliflozin outcome in EMPEROR-Preserved, which isn’t a certainty. They were more like the “boom” of a mortar launching a rocket of fireworks that may explode into a chrysanthemum or green comet or, sometimes, turn out to be no more than a dud. The promise of the early cursory results critically depends on further details.

“Provided there is a compelling benefit, this is what everyone has been waiting for in this condition for decades,” Mikhail N. Kosiborod, MD, director of cardiometabolic research at Saint Luke’s Mid-America Heart Institute, Kansas City, Mo., said.

“Already knowing that the trial met the primary endpoint is obviously very intriguing and encouraging,” he added. “But there are things we don’t know, such as: What is the magnitude of benefit? And whether that benefit, whatever the magnitude, is driven by reductions in both heart failure hospitalizations and cardiovascular death, or only one of the two.”

For example: “If we see an impressive benefit for reduction of hospitalizations, but not a significant reduction in death, that would still be a huge advance. That’s because, to date, we don’t have any drug for HFpEF that has convincingly demonstrated a compelling reduction in heart failure hospitalization or improvement in symptoms, function, or quality of life,” observed Dr. Kosiborod, who wasn’t part of EMPEROR-Preserved.

There have been “suggestions” from HFrEF trials that empagliflozin and dapagliflozin (Farxiga, AstraZeneca) “have very comparable effects on at least the endpoint of cardiovascular death or hospitalization for heart failure,” he said. “So, my expectation would be that whatever is observed in EMPEROR-Preserved is likely a class effect, as well.”

Following EMPEROR-Preserved on the agenda is EMPEROR-Pooled, a patient-level combined analysis of the EMPEROR series of trials that spans the range of HF, regardless of ejection fraction or diabetes status, primarily exploring the effects of empagliflozin on renal function.
 

Other offerings, Friday, Aug. 27

Scheduled immediately after EMPEROR-Preserved is a presentation on the SMART-MI trial, which should clarify whether management guided by continuous ambulatory monitoring is effective in patients considered at especially high arrhythmic risk. Entry called for recent myocardial infarction and an LVEF of 36%-50% with evidence of cardiac autonomic dysfunction.

The trial randomly assigned 400 such patients to be or not be implanted with a Reveal LINQ (Medtronic) loop recorder and followed them for up to 18 months, primarily for detection of potentially serious arrhythmic events. Endpoints that involved mortality, hospitalization or other clinical events were secondary.

In a time slot preceding both SMART-MI and EMPEROR-Preserved, the GUIDE-HF trial is following a projected 3,600 patients with HF implanted with a CardioMEMS HF System (Abbott) pulmonary artery (PA) pressure sensor to explore the its value for guiding management.

The trial’s three cohorts, followed for at least 12 months, include randomized sensor-monitored and control groups of patients with New York Heart Association class 2-4 symptoms, as well as a third observational set of patients in NYHA class 3. That’s the indication for which the CardioMEMS monitor gained approval in the United States in 2014 based on the 2011 CHAMPION trial, and which fared just as well in the 2017 CHAMPION Post-Approval Study.

The Friday Hot Lines also include Dal-GenE, which has entered about 6,000 patients with recent MI to test the once-abandoned cholesterol ester transfer protein (CETP) inhibitor dalcetrapib (DalCor) for any secondary-prevention benefits when used selectively. The trial’s hook: All its patients are confirmed to have the AA genotype of the rs1967309 variant in the ADCY9 gene, which has been associated with a pronounced clinical response to CETP inhibition.

Saturday, Aug. 28

The direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists in patients with nonvalvular atrial fibrillation (AFib). But whether DOACs are similarly preferable in the growing world population of people who have undergone transcatheter aortic valve replacement (TAVR or TAVI), an issue explored with variable results in the ATLANTIS and GALILEO trials, is far from settled.

The ENVISAGE-TAVI AF trial explored the question for the factor X inhibitor edoxaban (Savaysa, Lixiana, Daiichi-Sankyo) in 1,400 patients with AFib and a transfemoral TAVR in the previous 5 days, who were randomly assigned to the DOAC or standard management along with discretionary antiplatelet therapy. They’ve been followed for up to 3 years for a composite endpoint of clinical events – including death, MI, and stroke – and for major bleeding.

The day will also feature MASTER DAPT, a comparison of two dual-antiplatelet therapy (DAPT) regimens in an estimated 4,300 patients considered to be high-risk for bleeding who had received the sirolimus-eluting Ultimaster (Terumo) coronary stent, which has a bioresorbable polymer coating.

Investigators have randomly assigned patients to receive either very-short-duration DAPT, for about a month after stenting, followed by a P2Y12 inhibitor alone for up to a year after the procedure; or a more conventional regimen of a P2Y12 inhibitor for 6-12 months with aspirin maintained for a total of 12 months.

Later that day, investigators from the FIGARO-DKD trial will present their results based on 7,437 patients with type 2 diabetes and chronic kidney disease (CKD), a much fuller version than the top-line findings announced by sponsor Bayer 3 months ago.

Those top-line results suggested that patients assigned to receive the nonsteroidal nonselective mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) on top of standard care benefited with a drop in risk for the primary endpoint of CV death or nonfatal CV events.

Finerenone was recently approved in the United States for treating patients with both type 2 diabetes and CKD based on the published FIDELIO-DKD trial, which had seen less CKD progression and fewer CV events in such patients who took the novel MRA.

Although similar in design to FIGARO-DKD, FIDELIO-DKD had entered fewer patients with early-stage diabetic kidney disease (DKD). That led researchers to pool the two trials’ populations to create a cohort that spans the spectrum of DKD severity. An analysis of the pooled cohort, dubbed FIDELITY, is on the schedule after FIGARO-DKD.

After FIDELITY is the prospective APAF-CRT trial that is following a projected 1,830 patients with permanent, symptomatic AFib and a recent hospitalization for AFib or HF and who were not good candidates for standard ablation. They were assigned to receive either atrioventricular junctional ablation followed by CRT, with or without a defibrillation, on top of optimal meds – a so-called “ablate-and-pace” strategy – or an implantable cardioverter defibrillator with rate-control drug therapy.

The new analysis represents the trial’s second phase in which mortality was followed for 4 years as the primary endpoint, in contrast to the previously reported initial phase that followed the first 102 patients for 2 years for the composite primary endpoint of death, worsening HF, and HF hospitalization. The first phase had halted enrollment before reaching its planned target of 280 patients after an interim analysis showed a significant benefit for ablate and pace. 

Next up: DECAAF 2, a randomized assessment of whether catheter ablation for AFib guided by delayed gadolinium enhancement on MRI, a proxy for scar tissue, can be more effective than standard AFib ablation by pulmonary vein isolation alone. An estimated 900 patients with persistent AFib who had never before undergone ablation for the arrhythmia were randomly assigned to one strategy or the other and followed for AFib recurrence over 18 months.
 

Sunday, Aug. 29

The TOMAHAWK trial aimed to clarify the optimal timing of invasive coronary angiography for resuscitated patients with non–ST-segment elevation out-of-hospital cardiac arrest, a broad population in a setting for which there is little randomized-trial guidance. Investigators randomly assigned 558 such patients to undergo immediate invasive angiography or to direct intensive care unit admission for initial standard care with discretionary delayed angiography. Patients were followed for all-cause mortality, with other clinical events and neurologic outcomes as secondary endpoints.

Next on the schedule, the RIPCORD-2 trial randomly assigned 1,100 patients with stable known or suspected coronary artery disease (CAD) to undergo conventional angiography alone or with added direct pressure-wire measurement of fractional flow reserve to guide management decisions. Primary outcomes include health care costs and patient-reported quality of life at 1 year.

Slated for later that day, the Asymptomatic Carotid Surgery Trial-2 (ACST-2) has entered an estimated 3600 patients with a substantial carotid artery narrowing not associated with symptoms but for which either carotid endarterectomy (CEA) or carotid artery stenting (CAS) was considered anatomically feasible. There also must have been “substantial uncertainty” regarding the optimal procedure choice.

The trial, conducted in 40 countries primarily in Europe and North America and launched in 2008, randomly assigned the patients to undergo either CEA or CAS, in both cases with appropriate medical therapy, and followed them for periprocedural events and up to 10 years for strokes and stroke-related events.

The LOOP study, which is to directly follow ACST-2, has explored whether screening for AFib using the Medtronic Reveal LINQ monitor in older patients with non-AFib stroke risk factors – with oral anticoagulation prescribed for those who test positive – can lower their risk for stroke or systemic embolism. It randomly assigned 6,000 such patients to care guided by the loop recorder or to standard care.

On a somewhat larger scale, the Salt Substitute and Stroke Study (SSaSS) randomly assigned a total of 20,996 people in about 600 villages across northern China and Tibet to sodium-restriction intervention and control groups by village. All participants had a history of stroke or were aged at least 60 years with uncontrolled hypertension.

As described by the trial’s online portal, participants in villages assigned to the intervention group were given a supply of a low-sodium, potassium-supplementing salt substitute to replace their own salt supplies, along with education on the health benefits of sodium restriction. Participants in control villages continued their normal diets and, at the trial’s beginning, received “advice to reduce their salt intake.” All were required to own a telephone.

Clinical events, including strokes and hospitalizations throughout a 5-year follow-up, were tracked by phone calls made to all participants every 6 months and were documented at follow-up home visits.

Sunday is also to feature a Late-Breaking Trials session with a focus on COVID-19, which leads off with COLCOVID, a test of colchicine in patients hospitalized for suspected SARS-CoV-2 infection and in acute respiratory distress.

The 1,279 participants in Argentina were randomly assigned to receive or not receive the potent anti-inflammatory agent on top of antivirals and other standard management and followed for death or new need for mechanical ventilation. A successful outcome would contrast with the RECOVERY trial, which terminated a colchicine group of patients hospitalized with COVID-19 because of a lack of efficacy earlier this year.

COLCOVID is to be followed by the MICHELLE trial of rivaroxaban (Xarelto, Bayer/Janssen) prophylaxis, compared with no preventive oral anticoagulant, in 320 patients who, when hospitalized with COVID-19, had been on parenteral anticoagulants because of an elevated risk for venous thromboembolism. The trial, conducted in Brazil, called for postdischarge rivaroxaban at a once-daily dosage of 10 mg for about 1 month.

The session also includes a presentation called “Insights into the Effects of the COVID-19 Pandemic: Comprehensive Analysis from the GUIDE-HF Trial,” the primary outcomes of which will be reported on the first day of the Congress.

Following is a presentation on the PREPARE-IT study of icosapent ethyl (Vascepa, Amarin), given at high dosages intended to be anti-inflammatory, compared with placebo, in an estimated 4,000 adults. The trial has two groups: A prevention group of adults living and circulating in the community; and a treatment group of patients aged at least 40 years with confirmed symptomatic SARS-CoV-2 infection for whom the need for hospitalization isn’t clear.
 

Monday, Aug. 30

The final day of the Congress features a trial called Influenza Vaccination after Myocardial Infarction (IAMI), which has tested the secondary preventive effect of influenza vaccination by randomly assigning 2,571 patients to receive a standard vaccine or a saline placebo injection on one occasion.

Entry to the international trial called for a diagnosis of MI with or without ST-segment elevation, or stable CAD and age at least 75 years with other risk factors. The patients were followed for death, MI, stent thrombosis, and a slew of secondary endpoints over 12 months.

Monday offerings continue later in a time block leading off with the STEP trial, which has randomly assigned an estimated 8,000 patients at 40 centers in China who are 60 to 80 years of age with a systolic blood pressure of 140 to <190 mm Hg to be on standard guideline-based therapy or an intensive drug-management strategy.

The systolic BP goals are 130 to <150 mm Hg for standard care and 110 to <130 mm Hg for the intensive regimen. The composite primary endpoint includes death and clinical events related to acute coronary syndromes, HF, revascularization, and stroke.

Following on heels of STEP, the Amulet IDE trial – the first major randomized comparison of two transcatheter LAA closure devices – entered 1,878 patients with nonvalvular AFib who were considered high-risk for bleeding and stroke or systemic embolism.

They were randomly assigned in the noninferiority trial to receive either the AMPLATZER Amulet (Abbott Medical Devices) or the WATCHMAN (Boston Scientific) closure devices and were followed for safety and efficacy for up to 5 years.

Both LAA closure devices, intended to make patients with AFib less reliant on oral anticoagulation, are now available on both sides of the Atlantic – as well as many other countries – after the Amulet’s United States market approval on Aug. 16, based largely on the Amulet IDE trial.

Rounding out the final Hot Line set is one of the latest efforts to show the efficacy and safety of a very short DAPT period after coronary stenting in patients with acute coronary syndromes, the STOPDAPT-2 ACS trial.

The study assigned 3,008 patients in Japan to receive aspirin and clopidogrel for either 1 month or 1 year after implantation with an everolimus-eluting cobalt-chromium stent and followed them for up to 5 years for a composite of MI, CV death, stent thrombosis, stroke, and bleeding.

The trial follows the published STOPDAPT-2 trial that showed superiority for the 1-month DAPT regimen in a predominantly stable-CAD population treated with the same kind of stent.
 

Program structure and format

A total of 15 online channels are to be available in the morning, European time, their schedules running in parallel. Presentations often are prerecorded, but also include live sessions at 8:00 a.m. Central time and 12 p.m. CET (2:00 a.m. and 6:00 a.m. Eastern time) to liven up the channel offerings, Dr. Windecker observed, and to make them more immediate and potentially interactive.

Many of the parallel channels are devoted throughout the Congress to particular silos of cardiology; for example, arrhythmias and device therapy is on channel 3; CAD and acute care is on 5; HF is on 6; and preventive cardiology is on 9.

Other channels swing across different topics from day to day, such as channel 1, which covers COVID-19 topics on the first and third day of the meeting, “advances in science” on day 2, and “digital health, public health, health economics” on day 4.

The focus each day, starting at 2:00 p.m. CET (8:00 a.m. ET) and continuing into the evening in Europe, shifts over to the Prime Time live program, which features the Hot Line and guideline presentations and many of the live abstract presentations.

Dr. Kosiborod, not a researcher with the EMPEROR trials, is chair of the Dapagliflozin in Preserved Ejection Fraction Heart Failure ( PRESERVED-HF ) trial, which is scheduled for presentation at the September 2021 Heart Failure Society of American meeting.

A version of this article first appeared on Medscape.com.

There will be so much more to the annual congress of the European Society of Cardiology, which begins Aug. 27 with an all-virtual format, than detailed primary results of EMPEROR-Preserved, a trial that could mark a turning point for heart failure (HF) medical therapy.

Also among the featured Hot Line and Late-Breaking Science sessions are – along with many other studies – explorations of arrhythmia management (ablation or guided by loop recorder); secondary prevention, including by vaccination; oral anticoagulation, notably after transcatheter valve procedures; and colchicine or thrombosis prophylaxis in hospitalized patients with COVID-19.

There will even be a head-to-head comparison of two long-familiar left atrial appendage (LAA) occluders, and a population-based, randomized trial of sodium restriction through wide-scale use of a potassium-based salt substitute.

The congress will also introduce four guideline documents at sessions throughout the Congress, one on each day. They cover new and modified recommendations for heart failure; pacing, including cardiac resynchronization therapy (CRT); cardiovascular (CV) disease prevention; and, with cosponsorship from the European Association for Cardio-Thoracic Surgery, valvular heart disease.
 

The virtues of virtual

That next year’s Congress is slated for Aug. 27-30 in Barcelona should be welcome news for anyone whose “what if” curiosity about all-virtual conferences has already been satisfied. But with experience comes wisdom, as the medical societies have learned that online scientific meetings have some winning qualities that may be worth keeping, as least for a while.

“I think there is no doubt that the digital format will continue, for several reasons. One is that this pandemic is not over,” ESC Congress program committee chair Stephan Windecker, MD, Bern (Switzerland) University Hospital, , told this news organization. “As long as it is not over, the digital format is here to stay.”

But it also appears that people who haven’t been able to attend the congress in person are keen to log in and engage online, Dr. Windecker said. The 2020 all-virtual conference drew a much younger pool of registrants, on average, than did the live conferences before the pandemic.

“I think that’s an indication of people that may be in training, in early stages of their career, or they don’t have the support from departments or from their practice, or other financial means.” But they are able to participate via computer, tablet, or smartphone, he said.

“Another advantage is that the recorded content can be replayed at the convenience of whoever wants to consume it at a later point in time,” he added. “Those are just some examples why the digital format is likely to stay,” on its own or in a new age of hybrid meetings.  
 

New and updated guidelines

Leading off the guideline series is the document on diagnosis and treatment of acute and chronic HF, which leveraged the past few busy years of HF clinical trials to arrive at a number of new recommendations and strengthened level-of-evidence ratings. It covers both drug and device therapy of HF with reduced ejection fraction (HFrEF) and acute decompensated HF, and tweaks and further enshrines the concept of HF with mildly reduced ejection fraction (HFmrEF).

Several updated recommendations for both long-used and novel medications, notably the sodium-glucose cotransporter 2 inhibitors, will be included because of the recently appreciated evidence-based impact in HFrEF, Dr. Windecker noted.

“I think it will be particularly interesting to look for the SGLT2 inhibitors as not a completely new class of drugs, but certainly one where there has been a lot of new evidence, to look at how those drugs will be integrated in the overall care pathway.”

A top-line preview of the new HF guideline limited to drug therapy, presented at July’s Heart Failure Association of the European Society of Cardiology (ESC-HFA), provided a simple answer to a common question in the new, bountiful age of HFrEF medications: Which meds, initiated in what order?

As it happens, the new recommendation for first-line HFrEF drug therapy is not a silver bullet, but a shotgun – prompt initiation of at least four meds, one from each of four drug classes: renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRA), and SGLT2 inhibitors. Each class, as described in the document, is to be started as soon as safely feasible, in a sequence deemed appropriate for each individual patient.
 

Spotlight on EMPEROR-Preserved

The world already knows that the trial, which tested the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) on top of standard therapy, “met” its primary endpoint in almost 6,000 patients with HF with preserved ejection fraction (HFpEF), who included some with HFmrEF by more contemporary definitions.

That means patients in EMPEROR-Preserved assigned to take empagliflozin showed significantly fewer events that made up the study’s primary endpoint, a composite of CV death or HF hospitalization. It appears to be the first clearly significant overall medical therapy benefit for a clinical primary endpoint in a major randomized HFpEF drug trial.

And that, pending fuller presentation of trial results at the Congress on Aug. 27, could be a huge deal for the half of HF patients with left ventricular ejection fractions (LVEF) higher than the HFrEF range.

Those early top-line results weren’t a decisive bombshell for a field now filled with hope for a practice-changing empagliflozin outcome in EMPEROR-Preserved, which isn’t a certainty. They were more like the “boom” of a mortar launching a rocket of fireworks that may explode into a chrysanthemum or green comet or, sometimes, turn out to be no more than a dud. The promise of the early cursory results critically depends on further details.

“Provided there is a compelling benefit, this is what everyone has been waiting for in this condition for decades,” Mikhail N. Kosiborod, MD, director of cardiometabolic research at Saint Luke’s Mid-America Heart Institute, Kansas City, Mo., said.

“Already knowing that the trial met the primary endpoint is obviously very intriguing and encouraging,” he added. “But there are things we don’t know, such as: What is the magnitude of benefit? And whether that benefit, whatever the magnitude, is driven by reductions in both heart failure hospitalizations and cardiovascular death, or only one of the two.”

For example: “If we see an impressive benefit for reduction of hospitalizations, but not a significant reduction in death, that would still be a huge advance. That’s because, to date, we don’t have any drug for HFpEF that has convincingly demonstrated a compelling reduction in heart failure hospitalization or improvement in symptoms, function, or quality of life,” observed Dr. Kosiborod, who wasn’t part of EMPEROR-Preserved.

There have been “suggestions” from HFrEF trials that empagliflozin and dapagliflozin (Farxiga, AstraZeneca) “have very comparable effects on at least the endpoint of cardiovascular death or hospitalization for heart failure,” he said. “So, my expectation would be that whatever is observed in EMPEROR-Preserved is likely a class effect, as well.”

Following EMPEROR-Preserved on the agenda is EMPEROR-Pooled, a patient-level combined analysis of the EMPEROR series of trials that spans the range of HF, regardless of ejection fraction or diabetes status, primarily exploring the effects of empagliflozin on renal function.
 

Other offerings, Friday, Aug. 27

Scheduled immediately after EMPEROR-Preserved is a presentation on the SMART-MI trial, which should clarify whether management guided by continuous ambulatory monitoring is effective in patients considered at especially high arrhythmic risk. Entry called for recent myocardial infarction and an LVEF of 36%-50% with evidence of cardiac autonomic dysfunction.

The trial randomly assigned 400 such patients to be or not be implanted with a Reveal LINQ (Medtronic) loop recorder and followed them for up to 18 months, primarily for detection of potentially serious arrhythmic events. Endpoints that involved mortality, hospitalization or other clinical events were secondary.

In a time slot preceding both SMART-MI and EMPEROR-Preserved, the GUIDE-HF trial is following a projected 3,600 patients with HF implanted with a CardioMEMS HF System (Abbott) pulmonary artery (PA) pressure sensor to explore the its value for guiding management.

The trial’s three cohorts, followed for at least 12 months, include randomized sensor-monitored and control groups of patients with New York Heart Association class 2-4 symptoms, as well as a third observational set of patients in NYHA class 3. That’s the indication for which the CardioMEMS monitor gained approval in the United States in 2014 based on the 2011 CHAMPION trial, and which fared just as well in the 2017 CHAMPION Post-Approval Study.

The Friday Hot Lines also include Dal-GenE, which has entered about 6,000 patients with recent MI to test the once-abandoned cholesterol ester transfer protein (CETP) inhibitor dalcetrapib (DalCor) for any secondary-prevention benefits when used selectively. The trial’s hook: All its patients are confirmed to have the AA genotype of the rs1967309 variant in the ADCY9 gene, which has been associated with a pronounced clinical response to CETP inhibition.

Saturday, Aug. 28

The direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists in patients with nonvalvular atrial fibrillation (AFib). But whether DOACs are similarly preferable in the growing world population of people who have undergone transcatheter aortic valve replacement (TAVR or TAVI), an issue explored with variable results in the ATLANTIS and GALILEO trials, is far from settled.

The ENVISAGE-TAVI AF trial explored the question for the factor X inhibitor edoxaban (Savaysa, Lixiana, Daiichi-Sankyo) in 1,400 patients with AFib and a transfemoral TAVR in the previous 5 days, who were randomly assigned to the DOAC or standard management along with discretionary antiplatelet therapy. They’ve been followed for up to 3 years for a composite endpoint of clinical events – including death, MI, and stroke – and for major bleeding.

The day will also feature MASTER DAPT, a comparison of two dual-antiplatelet therapy (DAPT) regimens in an estimated 4,300 patients considered to be high-risk for bleeding who had received the sirolimus-eluting Ultimaster (Terumo) coronary stent, which has a bioresorbable polymer coating.

Investigators have randomly assigned patients to receive either very-short-duration DAPT, for about a month after stenting, followed by a P2Y12 inhibitor alone for up to a year after the procedure; or a more conventional regimen of a P2Y12 inhibitor for 6-12 months with aspirin maintained for a total of 12 months.

Later that day, investigators from the FIGARO-DKD trial will present their results based on 7,437 patients with type 2 diabetes and chronic kidney disease (CKD), a much fuller version than the top-line findings announced by sponsor Bayer 3 months ago.

Those top-line results suggested that patients assigned to receive the nonsteroidal nonselective mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) on top of standard care benefited with a drop in risk for the primary endpoint of CV death or nonfatal CV events.

Finerenone was recently approved in the United States for treating patients with both type 2 diabetes and CKD based on the published FIDELIO-DKD trial, which had seen less CKD progression and fewer CV events in such patients who took the novel MRA.

Although similar in design to FIGARO-DKD, FIDELIO-DKD had entered fewer patients with early-stage diabetic kidney disease (DKD). That led researchers to pool the two trials’ populations to create a cohort that spans the spectrum of DKD severity. An analysis of the pooled cohort, dubbed FIDELITY, is on the schedule after FIGARO-DKD.

After FIDELITY is the prospective APAF-CRT trial that is following a projected 1,830 patients with permanent, symptomatic AFib and a recent hospitalization for AFib or HF and who were not good candidates for standard ablation. They were assigned to receive either atrioventricular junctional ablation followed by CRT, with or without a defibrillation, on top of optimal meds – a so-called “ablate-and-pace” strategy – or an implantable cardioverter defibrillator with rate-control drug therapy.

The new analysis represents the trial’s second phase in which mortality was followed for 4 years as the primary endpoint, in contrast to the previously reported initial phase that followed the first 102 patients for 2 years for the composite primary endpoint of death, worsening HF, and HF hospitalization. The first phase had halted enrollment before reaching its planned target of 280 patients after an interim analysis showed a significant benefit for ablate and pace. 

Next up: DECAAF 2, a randomized assessment of whether catheter ablation for AFib guided by delayed gadolinium enhancement on MRI, a proxy for scar tissue, can be more effective than standard AFib ablation by pulmonary vein isolation alone. An estimated 900 patients with persistent AFib who had never before undergone ablation for the arrhythmia were randomly assigned to one strategy or the other and followed for AFib recurrence over 18 months.
 

Sunday, Aug. 29

The TOMAHAWK trial aimed to clarify the optimal timing of invasive coronary angiography for resuscitated patients with non–ST-segment elevation out-of-hospital cardiac arrest, a broad population in a setting for which there is little randomized-trial guidance. Investigators randomly assigned 558 such patients to undergo immediate invasive angiography or to direct intensive care unit admission for initial standard care with discretionary delayed angiography. Patients were followed for all-cause mortality, with other clinical events and neurologic outcomes as secondary endpoints.

Next on the schedule, the RIPCORD-2 trial randomly assigned 1,100 patients with stable known or suspected coronary artery disease (CAD) to undergo conventional angiography alone or with added direct pressure-wire measurement of fractional flow reserve to guide management decisions. Primary outcomes include health care costs and patient-reported quality of life at 1 year.

Slated for later that day, the Asymptomatic Carotid Surgery Trial-2 (ACST-2) has entered an estimated 3600 patients with a substantial carotid artery narrowing not associated with symptoms but for which either carotid endarterectomy (CEA) or carotid artery stenting (CAS) was considered anatomically feasible.

Clinical events, including strokes and hospitalizations throughout a 5-year follow-up, were tracked by phone calls made to all participants every 6 months and were documented at follow-up home visits.

Sunday is also to feature a Late-Breaking Trials session with a focus on COVID-19, which leads off with COLCOVID, a test of colchicine in patients hospitalized for suspected SARS-CoV-2 infection and in acute respiratory distress.

As it happens, the new recommendation for first-line HFrEF drug therapy is not a silver bullet, but a shotgun – prompt initiation of at least four meds, one from each of four drug classes: renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRA), and SGLT2 inhibitors. Each class, as described in the document, is to be started as soon as safely feasible, in a sequence deemed appropriate for each individual patient.
 

Spotlight on EMPEROR-Preserved

The world already knows that the trial, which tested the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) on top of standard therapy, “met” its primary endpoint in almost 6,000 patients with HF with preserved ejection fraction (HFpEF), who included some with HFmrEF by more contemporary definitions.

That means patients in EMPEROR-Preserved assigned to take empagliflozin showed significantly fewer events that made up the study’s primary endpoint, a composite of CV death or HF hospitalization. It appears to be the first clearly significant overall medical therapy benefit for a clinical primary endpoint in a major randomized HFpEF drug trial.

And that, pending fuller presentation of trial results at the Congress on Aug. 27, could be a huge deal for the half of HF patients with left ventricular ejection fractions (LVEF) higher than the HFrEF range.

Those early top-line results weren’t a decisive bombshell for a field now filled with hope for a practice-changing empagliflozin outcome in EMPEROR-Preserved, which isn’t a certainty. They were more like the “boom” of a mortar launching a rocket of fireworks that may explode into a chrysanthemum or green comet or, sometimes, turn out to be no more than a dud. The promise of the early cursory results critically depends on further details.

“Provided there is a compelling benefit, this is what everyone has been waiting for in this condition for decades,” Mikhail N. Kosiborod, MD, director of cardiometabolic research at Saint Luke’s Mid-America Heart Institute, Kansas City, Mo., said.

“Already knowing that the trial met the primary endpoint is obviously very intriguing and encouraging,” he added. “But there are things we don’t know, such as: What is the magnitude of benefit? And whether that benefit, whatever the magnitude, is driven by reductions in both heart failure hospitalizations and cardiovascular death, or only one of the two.”

For example: “If we see an impressive benefit for reduction of hospitalizations, but not a significant reduction in death, that would still be a huge advance. That’s because, to date, we don’t have any drug for HFpEF that has convincingly demonstrated a compelling reduction in heart failure hospitalization or improvement in symptoms, function, or quality of life,” observed Dr. Kosiborod, who wasn’t part of EMPEROR-Preserved.

There have been “suggestions” from HFrEF trials that empagliflozin and dapagliflozin (Farxiga, AstraZeneca) “have very comparable effects on at least the endpoint of cardiovascular death or hospitalization for heart failure,” he said. “So, my expectation would be that whatever is observed in EMPEROR-Preserved is likely a class effect, as well.”

Following EMPEROR-Preserved on the agenda is EMPEROR-Pooled, a patient-level combined analysis of the EMPEROR series of trials that spans the range of HF, regardless of ejection fraction or diabetes status, primarily exploring the effects of empagliflozin on renal function.
 

Other offerings, Friday, Aug. 27

Scheduled immediately after EMPEROR-Preserved is a presentation on the SMART-MI trial, which should clarify whether management guided by continuous ambulatory monitoring is effective in patients considered at especially high arrhythmic risk. Entry called for recent myocardial infarction and an LVEF of 36%-50% with evidence of cardiac autonomic dysfunction.

The trial randomly assigned 400 such patients to be or not be implanted with a Reveal LINQ (Medtronic) loop recorder and followed them for up to 18 months, primarily for detection of potentially serious arrhythmic events. Endpoints that involved mortality, hospitalization or other clinical events were secondary.

In a time slot preceding both SMART-MI and EMPEROR-Preserved, the GUIDE-HF trial is following a projected 3,600 patients with HF implanted with a CardioMEMS HF System (Abbott) pulmonary artery (PA) pressure sensor to explore the its value for guiding management.

The trial’s three cohorts, followed for at least 12 months, include randomized sensor-monitored and control groups of patients with New York Heart Association class 2-4 symptoms, as well as a third observational set of patients in NYHA class 3. That’s the indication for which the CardioMEMS monitor gained approval in the United States in 2014 based on the 2011 CHAMPION trial, and which fared just as well in the 2017 CHAMPION Post-Approval Study.

The Friday Hot Lines also include Dal-GenE, which has entered about 6,000 patients with recent MI to test the once-abandoned cholesterol ester transfer protein (CETP) inhibitor dalcetrapib (DalCor) for any secondary-prevention benefits when used selectively. The trial’s hook: All its patients are confirmed to have the AA genotype of the rs1967309 variant in the ADCY9 gene, which has been associated with a pronounced clinical response to CETP inhibition.

Saturday, Aug. 28

The direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists in patients with nonvalvular atrial fibrillation (AFib). But whether DOACs are similarly preferable in the growing world population of people who have undergone transcatheter aortic valve replacement (TAVR or TAVI), an issue explored with variable results in the ATLANTIS and GALILEO trials, is far from settled.

The ENVISAGE-TAVI AF trial explored the question for the factor X inhibitor edoxaban (Savaysa, Lixiana, Daiichi-Sankyo) in 1,400 patients with AFib and a transfemoral TAVR in the previous 5 days, who were randomly assigned to the DOAC or standard management along with discretionary antiplatelet therapy. They’ve been followed for up to 3 years for a composite endpoint of clinical events – including death, MI, and stroke – and for major bleeding.

The day will also feature MASTER DAPT, a comparison of two dual-antiplatelet therapy (DAPT) regimens in an estimated 4,300 patients considered to be high-risk for bleeding who had received the sirolimus-eluting Ultimaster (Terumo) coronary stent, which has a bioresorbable polymer coating.

Investigators have randomly assigned patients to receive either very-short-duration DAPT, for about a month after stenting, followed by a P2Y12 inhibitor alone for up to a year after the procedure; or a more conventional regimen of a P2Y12 inhibitor for 6-12 months with aspirin maintained for a total of 12 months.

Later that day, investigators from the FIGARO-DKD trial will present their results based on 7,437 patients with type 2 diabetes and chronic kidney disease (CKD), a much fuller version than the top-line findings announced by sponsor Bayer 3 months ago.

Those top-line results suggested that patients assigned to receive the nonsteroidal nonselective mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) on top of standard care benefited with a drop in risk for the primary endpoint of CV death or nonfatal CV events.

Finerenone was recently approved in the United States for treating patients with both type 2 diabetes and CKD based on the published FIDELIO-DKD trial, which had seen less CKD progression and fewer CV events in such patients who took the novel MRA.

Although similar in design to FIGARO-DKD, FIDELIO-DKD had entered fewer patients with early-stage diabetic kidney disease (DKD). That led researchers to pool the two trials’ populations to create a cohort that spans the spectrum of DKD severity. An analysis of the pooled cohort, dubbed FIDELITY, is on the schedule after FIGARO-DKD.

After FIDELITY is the prospective APAF-CRT trial that is following a projected 1,830 patients with permanent, symptomatic AFib and a recent hospitalization for AFib or HF and who were not good candidates for standard ablation. They were assigned to receive either atrioventricular junctional ablation followed by CRT, with or without a defibrillation, on top of optimal meds – a so-called “ablate-and-pace” strategy – or an implantable cardioverter defibrillator with rate-control drug therapy.

The new analysis represents the trial’s second phase in which mortality was followed for 4 years as the primary endpoint, in contrast to the previously reported initial phase that followed the first 102 patients for 2 years for the composite primary endpoint of death, worsening HF, and HF hospitalization. The first phase had halted enrollment before reaching its planned target of 280 patients after an interim analysis showed a significant benefit for ablate and pace. 

Next up: DECAAF 2, a randomized assessment of whether catheter ablation for AFib guided by delayed gadolinium enhancement on MRI, a proxy for scar tissue, can be more effective than standard AFib ablation by pulmonary vein isolation alone. An estimated 900 patients with persistent AFib who had never before undergone ablation for the arrhythmia were randomly assigned to one strategy or the other and followed for AFib recurrence over 18 months.
 

Sunday, Aug. 29

The TOMAHAWK trial aimed to clarify the optimal timing of invasive coronary angiography for resuscitated patients with non–ST-segment elevation out-of-hospital cardiac arrest, a broad population in a setting for which there is little randomized-trial guidance. Investigators randomly assigned 558 such patients to undergo immediate invasive angiography or to direct intensive care unit admission for initial standard care with discretionary delayed angiography. Patients were followed for all-cause mortality, with other clinical events and neurologic outcomes as secondary endpoints.

Next on the schedule, the RIPCORD-2 trial randomly assigned 1,100 patients with stable known or suspected coronary artery disease (CAD) to undergo conventional angiography alone or with added direct pressure-wire measurement of fractional flow reserve to guide management decisions. Primary outcomes include health care costs and patient-reported quality of life at 1 year.

Slated for later that day, the Asymptomatic Carotid Surgery Trial-2 (ACST-2) has entered an estimated 3600 patients with a substantial carotid artery narrowing not associated with symptoms but for which either carotid endarterectomy (CEA) or carotid artery stenting (CAS) was considered anatomically feasible. There also must have been “substantial uncertainty” regarding the optimal procedure choice.

The trial, conducted in 40 countries primarily in Europe and North America and launched in 2008, randomly assigned the patients to undergo either CEA or CAS, in both cases with appropriate medical therapy, and followed them for periprocedural events and up to 10 years for strokes and stroke-related events.

The LOOP study, which is to directly follow ACST-2, has explored whether screening for AFib using the Medtronic Reveal LINQ monitor in older patients with non-AFib stroke risk factors – with oral anticoagulation prescribed for those who test positive – can lower their risk for stroke or systemic embolism. It randomly assigned 6,000 such patients to care guided by the loop recorder or to standard care.

On a somewhat larger scale, the Salt Substitute and Stroke Study (SSaSS) randomly assigned a total of 20,996 people in about 600 villages across northern China and Tibet to sodium-restriction intervention and control groups by village. All participants had a history of stroke or were aged at least 60 years with uncontrolled hypertension.

As described by the trial’s online portal, participants in villages assigned to the intervention group were given a supply of a low-sodium, potassium-supplementing salt substitute to replace their own salt supplies, along with education on the health benefits of sodium restriction. Participants in control villages continued their normal diets and, at the trial’s beginning, received “advice to reduce their salt intake.” All were required to own a telephone.

Clinical events, including strokes and hospitalizations throughout a 5-year follow-up, were tracked by phone calls made to all participants every 6 months and were documented at follow-up home visits.

Sunday is also to feature a Late-Breaking Trials session with a focus on COVID-19, which leads off with COLCOVID, a test of colchicine in patients hospitalized for suspected SARS-CoV-2 infection and in acute respiratory distress.

The 1,279 participants in Argentina were randomly assigned to receive or not receive the potent anti-inflammatory agent on top of antivirals and other standard management and followed for death or new need for mechanical ventilation. A successful outcome would contrast with the RECOVERY trial, which terminated a colchicine group of patients hospitalized with COVID-19 because of a lack of efficacy earlier this year.

COLCOVID is to be followed by the MICHELLE trial of rivaroxaban (Xarelto, Bayer/Janssen) prophylaxis, compared with no preventive oral anticoagulant, in 320 patients who, when hospitalized with COVID-19, had been on parenteral anticoagulants because of an elevated risk for venous thromboembolism. The trial, conducted in Brazil, called for postdischarge rivaroxaban at a once-daily dosage of 10 mg for about 1 month.

The session also includes a presentation called “Insights into the Effects of the COVID-19 Pandemic: Comprehensive Analysis from the GUIDE-HF Trial,” the primary outcomes of which will be reported on the first day of the Congress.

Following is a presentation on the PREPARE-IT study of icosapent ethyl (Vascepa, Amarin), given at high dosages intended to be anti-inflammatory, compared with placebo, in an estimated 4,000 adults. The trial has two groups: A prevention group of adults living and circulating in the community; and a treatment group of patients aged at least 40 years with confirmed symptomatic SARS-CoV-2 infection for whom the need for hospitalization isn’t clear.
 

Monday, Aug. 30

The final day of the Congress features a trial called Influenza Vaccination after Myocardial Infarction (IAMI), which has tested the secondary preventive effect of influenza vaccination by randomly assigning 2,571 patients to receive a standard vaccine or a saline placebo injection on one occasion.

Entry to the international trial called for a diagnosis of MI with or without ST-segment elevation, or stable CAD and age at least 75 years with other risk factors. The patients were followed for death, MI, stent thrombosis, and a slew of secondary endpoints over 12 months.

Monday offerings continue later in a time block leading off with the STEP trial, which has randomly assigned an estimated 8,000 patients at 40 centers in China who are 60 to 80 years of age with a systolic blood pressure of 140 to <190 mm Hg to be on standard guideline-based therapy or an intensive drug-management strategy.

The systolic BP goals are 130 to <150 mm Hg for standard care and 110 to <130 mm Hg for the intensive regimen. The composite primary endpoint includes death and clinical events related to acute coronary syndromes, HF, revascularization, and stroke.

Following on heels of STEP, the Amulet IDE trial – the first major randomized comparison of two transcatheter LAA closure devices – entered 1,878 patients with nonvalvular AFib who were considered high-risk for bleeding and stroke or systemic embolism.

They were randomly assigned in the noninferiority trial to receive either the AMPLATZER Amulet (Abbott Medical Devices) or the WATCHMAN (Boston Scientific) closure devices and were followed for safety and efficacy for up to 5 years.

Both LAA closure devices, intended to make patients with AFib less reliant on oral anticoagulation, are now available on both sides of the Atlantic – as well as many other countries – after the Amulet’s United States market approval on Aug. 16, based largely on the Amulet IDE trial.

Rounding out the final Hot Line set is one of the latest efforts to show the efficacy and safety of a very short DAPT period after coronary stenting in patients with acute coronary syndromes, the STOPDAPT-2 ACS trial.

The study assigned 3,008 patients in Japan to receive aspirin and clopidogrel for either 1 month or 1 year after implantation with an everolimus-eluting cobalt-chromium stent and followed them for up to 5 years for a composite of MI, CV death, stent thrombosis, stroke, and bleeding.

The trial follows the published STOPDAPT-2 trial that showed superiority for the 1-month DAPT regimen in a predominantly stable-CAD population treated with the same kind of stent.
 

Program structure and format

A total of 15 online channels are to be available in the morning, European time, their schedules running in parallel. Presentations often are prerecorded, but also include live sessions at 8:00 a.m. Central time and 12 p.m. CET (2:00 a.m. and 6:00 a.m. Eastern time) to liven up the channel offerings, Dr. Windecker observed, and to make them more immediate and potentially interactive.

Many of the parallel channels are devoted throughout the Congress to particular silos of cardiology; for example, arrhythmias and device therapy is on channel 3; CAD and acute care is on 5; HF is on 6; and preventive cardiology is on 9.

Other channels swing across different topics from day to day, such as channel 1, which covers COVID-19 topics on the first and third day of the meeting, “advances in science” on day 2, and “digital health, public health, health economics” on day 4.

The focus each day, starting at 2:00 p.m. CET (8:00 a.m. ET) and continuing into the evening in Europe, shifts over to the Prime Time live program, which features the Hot Line and guideline presentations and many of the live abstract presentations.

Dr. Kosiborod, not a researcher with the EMPEROR trials, is chair of the Dapagliflozin in Preserved Ejection Fraction Heart Failure ( PRESERVED-HF ) trial, which is scheduled for presentation at the September 2021 Heart Failure Society of American meeting.

Weekly cases of COVID-19 in children jumped by nearly 50% in the United States, posting the highest count since hitting a pandemic high back in mid-January, a new report shows.

The 180,175 new cases reported during Aug. 13-19 represent the highest 1-week total since the peak of 211,466 during the week of Jan. 8-14. The latest weekly figure represents a 48% increase over the previous week and an increase of over 2,000% in the 8 weeks since the national count dropped to a low of 8,500 cases for the week of June 18-24, the American Academy of Pediatrics and the Children’s Hospital Association said in their weekly COVID report.

Vaccinations, in the meantime, appear to be headed in the opposite direction. Vaccine initiations were down for the second consecutive week, falling by 18% among 12- to 15-year-olds and by 15% in those aged 16-17 years, according to data from the Centers for Disease Control and Prevention.

Nationally, about 47% of children aged 12-15 and 56% of those aged 16-17 have received at least one dose of COVID vaccine as of Aug. 23, with 34% and 44%, respectively, reaching full vaccination. The total number of children with at least one dose is 11.6 million, including a relatively small number (about 200,000) of children under age 12 years, the CDC said on its COVID Data Tracker.

At the state level, vaccination is a source of considerable disparity. In Vermont, 73% of children aged 12-17 had received at least one dose by Aug. 18, and 63% were fully vaccinated. In Wyoming, however, just 25% of children had received at least one dose (17% are fully vaccinated), while Alabama has a lowest-in-the-nation full vaccination rate of 14%, based on a separate AAP analysis of CDC data.

There are seven states in which over 60% of 12- to 17-year-olds have at least started the vaccine regimen and five states where less than 30% have received at least one dose, the AAP noted.

Back on the incidence side of the pandemic, Mississippi and Hawaii had the largest increases in new cases over the past 2 weeks, followed by Florida and West Virginia. Cumulative figures show that California has had the most cases overall in children (550,337), Vermont has the highest proportion of all cases in children (22.9%), and Rhode Island has the highest rate of cases per 100,000 (10,636), the AAP and CHA said in the joint report based on data from 49 states, the District of Columbia, New York City, Puerto Rico, and Guam.

Add up all those jurisdictions, and it works out to 4.6 million children infected with SARS-CoV-2 as of Aug. 19, with children representing 14.6% of all cases since the start of the pandemic. There have been over 18,000 hospitalizations so far, which is just 2.3% of the total for all ages in the 23 states (and New York City) that are reporting such data on their health department websites, the AAP and CHA said.

The number of COVID-related deaths in children is now 402 after the largest 1-week increase (24) since late May of 2020, when the AAP/CHA coverage began. Mortality data by age are available from 44 states, New York City, Puerto Rico, and Guam.

Kidney transplantation has recently been happening at a record pace and with unprecedented success despite patients having more risk factors than ever before.

HYWARDS/Thinkstock

During 2016-2019, U.S. centers performed kidney transplants in nearly 77,000 patients, a jump of almost 25% compared with 4-year averages of about 62,000 patients throughout 2004-2015. That works out to about 15,000 more patients receiving donor kidneys, Sundaram Hariharan, MD, and associates reported in the New England Journal of Medicine in a review of all U.S. renal transplantations performed during 1996-2019.

Coupled with the volume uptick during this 24-year period were new lows in graft losses and patient deaths. By 2018, mortality during the first year following transplantation occurred at about a 1% rate among patients who had received a kidney from a living donor, and at about a 3% rate when the organ came from a deceased donor, nearly half the rate of 2 decades earlier, in 1996. Rates of first-year graft loss during 2017 were also about half of what they had been in 1996, occurring in about 2% of patients who received a living donor organ and in about 6% of those who got a kidney from a deceased donor during 2017.

“Twenty years ago, kidney transplantation was the preferred option compared with dialysis, and even more so now,” summed up Dr. Hariharan, a senior transplant nephrologist and professor of medicine and surgery at the University of Pittsburgh Medical Center and first author of the report. Kidney transplantation survival at U.S. centers “improved steadily over the past 24 years, despite patient variables becoming worse,” he said in an interview.
 

Kidney recipients are older, more obese, and have more prevalent diabetes

During the period studied, kidney transplant recipients became on average older and more obese, and had a higher prevalence of diabetes; the age of organ donors grew as well. The prevalence of diabetes among patients who received a kidney from a deceased donor increased from 24% during 1996-1999 to 36% during 2016-2019, while diabetes prevalence among recipients of an organ from a living donor rose from 25% in 1996-1999 to 29% during 2016-2019.

The improved graft and patient survival numbers “are very encouraging trends,” said Michelle A. Josephson, MD, professor and medical director of kidney transplantation at the University of Chicago, who was not involved with the report. “We have been hearing for a number of years that short-term graft survival had improved, but I’m thrilled to learn that long-term survival has also improved.”

The report documented 10-year survival of graft recipients during 2008-2011 of 67%, up from 61% during 1996-1999, and a 10-year overall graft survival rate of 54% in the 2008-2011 cohort, an improvement from the 42% rate in patients who received their organs in 1996-1999, changes Dr. Hariharan characterized as “modest.”

These improvements in long-term graft and patient survival are “meaningful, and particularly notable that outcomes improved despite increased complexity of the transplant population,” said Krista L. Lentine, MD, PhD, professor and medical director of living donation at Saint Louis University. But “despite these improvements, long-term graft survival remains limited,” she cautioned, especially because of risks for substantial complications from chronic immunosuppressive treatment including infection, cancer, glucose intolerance, and dyslipidemia.

The analysis reported by Dr. Hariharan and his associates used data collected by the Scientific Registry of Transplant Patients, run under contract with the U.S. Department of Health and Human Services, which has tracked all patients who have had kidney transplants at U.S. centers since the late 1980s, said Dr. Hariharan. The database included just over 362,000 total transplants during the 24-year period studied, with 36% of all transplants involving organs from living donors with the remaining patients receiving kidneys from deceased donors.

Living donations still stagnant; deceased-donor kidneys rise

The data showed that the rate of transplants from living donors was stagnant for 2 decades, with 22,525 patients transplanted during 2000-2003, and 23,746 transplanted during 2016-2019, with very similar rates during the intervening years. The recent spurt in transplants during 2016-2019 compared with the preceding decade depended almost entirely on kidneys from deceased donors. This rate jumped from the steady, slow rise it showed during 1996-2015, when deceased-donor transplants rose from about 30,000 during 1996-1999 to about 41,000 during 2012-2015, to a more dramatic increase of about 12,000 additional transplants during the most recent period, adding up to a total of more than 53,000 transplants from deceased donors during 2016-2019.

“I strongly recommend organs from living donors” when feasible, said Dr. Hariharan. “At some centers, a high proportion of transplants use living donors, but not at other centers,” he said.

It’s unknown why transplants using organs from deceased donors has shown this growth, but Dr. Hariharan suggested a multifactorial explanation. Those factors include growth in the number of patients with end-stage renal disease who require dialysis, increased numbers of patients listed for kidney transplant, new approaches that allow organs from older donors and those infected with pathogens such as hepatitis C virus or HIV, greater numbers of people and families agreeing to donate organs, and possibly the opioid crisis that may have led to increased organ donation. The number of U.S. centers performing kidney transplants rose from fewer than 200 about a quarter of a century ago to about 250 today, he added.

‘Immuno Bill’ guarantees Medicare coverage for immunosuppression

Dr. Hariharan voiced optimism that graft and patient survival rates will continue to improve going forward. One factor will likely be the passage in late 2020 of the “Immuno Bill” by the U.S. Congress, which among other things mandated ongoing coverage starting in 2023 for immunosuppressive drugs for all Medicare beneficiaries with a kidney transplant. Until then, Medicare provides coverage for only 36 months, a time limit that has resulted in nearly 400 kidney recipients annually losing coverage of their immunosuppression medications.

Dr. Hariharan and coauthors called the existing potential for discontinuation of immunosuppressive drug an “unnecessary impediment to long-term survival for which patients and society paid a heavy price.”

“Kidney transplantation, especially from living donors, offers patients with kidney failure the best chance for long-term survival and improved quality of life, with lower cost to the health care system,” Dr. Lentine said in an interview. Despite the many positive trends detailed in the report from Dr. Hariharan and coauthors, “the vast majority of the more than 700,000 people in the United States with kidney failure will not have an opportunity to receive a transplant due to limitations in organ supply.” And many patients who receive a kidney transplant eventually must resume dialysis because of “limited long-term graft survival resulting from allograft nephropathy, recurrent native disease, medication nonadherence, or other causes.” Plus many potentially transplantable organs go unused.

Dr. Lentine cited a position statement issued in July 2021 by the National Kidney Foundation that made several recommendations on how to improve access to kidney transplants and improve outcomes. “Expanding opportunities for safe living donation, eliminating racial disparities in living-donor access, improving wait-list access and transport readiness, maximizing use of deceased-donor organs, and extending graft longevity are critical priorities,” said Dr. Lentine, lead author on the statement.

“For many or even most patients with kidney failure transplantation is the optimal form of renal replacement. The better recent outcomes and evolving management strategies make transplantation an even more attractive option,” said Dr. Josephson. Improved outcomes among U.S. transplant patients also highlights the “importance of increasing access to kidney transplantation” for all people with kidney failure who could benefit from this treatment, she added.

Kidney transplantation has recently been happening at a record pace and with unprecedented success despite patients having more risk factors than ever before.

HYWARDS/Thinkstock

During 2016-2019, U.S. centers performed kidney transplants in nearly 77,000 patients, a jump of almost 25% compared with 4-year averages of about 62,000 patients throughout 2004-2015. That works out to about 15,000 more patients receiving donor kidneys, Sundaram Hariharan, MD, and associates reported in the New England Journal of Medicine in a review of all U.S. renal transplantations performed during 1996-2019.

Coupled with the volume uptick during this 24-year period were new lows in graft losses and patient deaths. By 2018, mortality during the first year following transplantation occurred at about a 1% rate among patients who had received a kidney from a living donor, and at about a 3% rate when the organ came from a deceased donor, nearly half the rate of 2 decades earlier, in 1996. Rates of first-year graft loss during 2017 were also about half of what they had been in 1996, occurring in about 2% of patients who received a living donor organ and in about 6% of those who got a kidney from a deceased donor during 2017.

“Twenty years ago, kidney transplantation was the preferred option compared with dialysis, and even more so now,” summed up Dr. Hariharan, a senior transplant nephrologist and professor of medicine and surgery at the University of Pittsburgh Medical Center and first author of the report. Kidney transplantation survival at U.S. centers “improved steadily over the past 24 years, despite patient variables becoming worse,” he said in an interview.
 

Kidney recipients are older, more obese, and have more prevalent diabetes

During the period studied, kidney transplant recipients became on average older and more obese, and had a higher prevalence of diabetes; the age of organ donors grew as well. The prevalence of diabetes among patients who received a kidney from a deceased donor increased from 24% during 1996-1999 to 36% during 2016-2019, while diabetes prevalence among recipients of an organ from a living donor rose from 25% in 1996-1999 to 29% during 2016-2019.

The improved graft and patient survival numbers “are very encouraging trends,” said Michelle A. Josephson, MD, professor and medical director of kidney transplantation at the University of Chicago, who was not involved with the report. “We have been hearing for a number of years that short-term graft survival had improved, but I’m thrilled to learn that long-term survival has also improved.”

The report documented 10-year survival of graft recipients during 2008-2011 of 67%, up from 61% during 1996-1999, and a 10-year overall graft survival rate of 54% in the 2008-2011 cohort, an improvement from the 42% rate in patients who received their organs in 1996-1999, changes Dr. Hariharan characterized as “modest.”

These improvements in long-term graft and patient survival are “meaningful, and particularly notable that outcomes improved despite increased complexity of the transplant population,” said Krista L. Lentine, MD, PhD, professor and medical director of living donation at Saint Louis University. But “despite these improvements, long-term graft survival remains limited,” she cautioned, especially because of risks for substantial complications from chronic immunosuppressive treatment including infection, cancer, glucose intolerance, and dyslipidemia.

The analysis reported by Dr. Hariharan and his associates used data collected by the Scientific Registry of Transplant Patients, run under contract with the U.S. Department of Health and Human Services, which has tracked all patients who have had kidney transplants at U.S. centers since the late 1980s, said Dr. Hariharan. The database included just over 362,000 total transplants during the 24-year period studied, with 36% of all transplants involving organs from living donors with the remaining patients receiving kidneys from deceased donors.

Living donations still stagnant; deceased-donor kidneys rise

The data showed that the rate of transplants from living donors was stagnant for 2 decades, with 22,525 patients transplanted during 2000-2003, and 23,746 transplanted during 2016-2019, with very similar rates during the intervening years.

The United States Preventive Services Task Force has updated its recommendation on the age of screening for prediabetes and type 2 diabetes in the primary care setting – lowering the age from 40 to 35 years for asymptomatic patients who are overweight or obese and encouraging greater interventions when patients do show a risk.

KatarzynaBialasiewicz/Thinkstock

“The USPSTF concludes with moderate certainty that screening for prediabetes and type 2 diabetes and offering or referring patients with prediabetes to effective preventive interventions has a moderate net benefit,” the task force concludes in its recommendation, published Aug. 24 in JAMA.

“Clinicians should offer or refer patients with prediabetes to effective preventive interventions,” they write.

Experts commenting on the issue strongly emphasize that it’s not just the screening, but the subsequent intervention that is needed to make a difference.

“If young adults newly identified with abnormal glucose metabolism do not receive the needed intensive behavioral change support, screening may provide no benefit,” write Richard W. Grant, MD, MPH, and colleagues in an editorial published with the recommendation.

“Given the role of our obesogenic and physically inactive society in the shift toward earlier onset of diabetes, efforts to increase screening and recognition of abnormal glucose metabolism must be coupled with robust public health measures to address the underlying contributors.”
 

BMI cutoff lower for at-risk ethnic populations

The recommendation, which updates the task force’s 2015 guideline, carries a “B” classification, meaning the USPSTF has high certainty that the net benefit is moderate. It now specifies screening from age 35to 70 for persons classified as overweight (body mass index at least 25) or obese (BMI at least 30) and recommends referral to preventive interventions when patients are found to have prediabetes.

In addition to recommendations of lifestyle changes, such as diet and physical activity, the task force also endorses the diabetes drug metformin as a beneficial intervention in the prevention or delay of diabetes, while noting fewer overall health benefits from metformin than from the lifestyle changes.

A lower BMI cutoff of at least 23 is recommended for diabetes screening of Asian Americans, and, importantly, screening for prediabetes and diabetes should be considered at an even earlier age if the patient is from a population with a disproportionately high prevalence of diabetes, including American Indian/Alaska Native, Black, Hawaiian/Pacific Islander, Hispanic/Latino, the task force recommends.

Screening tests should include fasting plasma glucose, hemoglobin A1c, or an oral glucose tolerance test. Although screening every 3 years “may be a reasonable approach for adults with normal blood glucose levels,” the task force adds that “the optimal screening interval for adults with an initial normal glucose test result is uncertain.”
 

Data review: Few with prediabetes know they have it

The need for the update was prompted by troubling data showing increasing diabetes rates despite early signs that can and should be identified and acted upon in the primary care setting to prevent disease progression.

Data from the Centers for Disease Control and Prevention, for instance, show that while 13% of all U.S. adults 18 years or older have diabetes and 35% meet criteria for prediabetes, as many as 21% of those with diabetes were not aware of or did not report having the disease. Furthermore, only a small fraction – 15% of those with prediabetes – said they had been told by a health professional that they had this condition, the task force notes.

The task force’s final recommendation was based on a systematic review of evidence regarding the screening of asymptomatic, nonpregnant adults and the harms and benefits of interventions, such as physical activity, behavioral counseling, or pharmacotherapy.

Among key evidence supporting the lower age was a 2014 study showing that the number of people necessary to obtain one positive test for diabetes with screening sharply drops from 80 among those aged 30-34 years to just 31 among those aged 36-39.

Opportunistic universal screening of eligible people aged 35 and older would yield a ratio of 1 out of just 15 to spot a positive test, the authors of that study reported.

In addition, a large cohort study in more than 77,000 people with prediabetes strongly links the risk of developing diabetes with increases in A1c level and with increasing BMI.
 

ADA recommendations differ

The new recommendations differ from American Diabetes Association guidelines, which call for diabetes screening at all ages for people who are overweight or obese and who have one or more risk factors, such as physical inactivity or a first-degree relative with diabetes. If results are normal, repeat screening at least every 3 years is recommended.

The ADA further recommends universal screening for all adults 45 years and older, regardless of their risk factors.

For the screening of adults over 45, the ADA recommends using a fasting plasma glucose level, 2-hour plasma glucose level during a 75-g oral glucose tolerance test, or A1c level, regardless of risk factors.

The American Association of Clinical Endocrinology also recommends universal screening for prediabetes and diabetes for all adults 45 years or older, regardless of risk factors, and also advises screening those who have risk factors for diabetes regardless of age.
 

Screening of little benefit without behavior change support

In an interview, Dr. Grant added that broad efforts are essential as those at the practice level have clearly not succeeded.

“The medical model of individual counseling and referral has not really been effective, and so we really need to think in terms of large-scale public health action,” said Dr. Grant, of the division of research, Kaiser Permanente Northern California, Oakland.

His editorial details the sweeping, multifactorial efforts that are needed.

“To turn this recommendation into action – that is, to translate screening activities into improved clinical outcomes – change is needed at the patient-clinician level (recognizing and encouraging eligible individuals to be screened), health care system level (reducing screening barriers and ensuring access to robust lifestyle programs), and societal level (applying effective public health interventions to reduce obesity and increase exercise),” they write.

A top priority has to be a focus on individuals of diverse backgrounds and issues such as access to healthy programs in minority communities, Dr. Grant noted.

“Newly diagnosed adults are more likely to be African-American and Latinx,” he said.

“We really need to invest in healthier communities for low-income, non-White communities to reverse the persistent health care disparities in these communities.”

While the challenges may appear daunting, history shows they are not necessarily insurmountable – as evidenced in the campaign to discourage tobacco smoking.

“National smoking cessation efforts are one example of a mostly successful public health campaign that has made a difference in health behaviors,” Grant noted.

The recommendation is also posted on the USPSTF web site .

Dr. Grant reports receiving grants from the National Institutes of Health and the Patient-Centered Outcomes Research Institute.

The recommendation, which updates the task force’s 2015 guideline, carries a “B” classification, meaning the USPSTF has high certainty that the net benefit is moderate. It now specifies screening from age 35to 70 for persons classified as overweight (body mass index at least 25) or obese (BMI at least 30) and recommends referral to preventive interventions when patients are found to have prediabetes.

In addition to recommendations of lifestyle changes, such as diet and physical activity, the task force also endorses the diabetes drug metformin as a beneficial intervention in the prevention or delay of diabetes, while noting fewer overall health benefits from metformin than from the lifestyle changes.

A lower BMI cutoff of at least 23 is recommended for diabetes screening of Asian Americans, and, importantly, screening for prediabetes and diabetes should be considered at an even earlier age if the patient is from a population with a disproportionately high prevalence of diabetes, including American Indian/Alaska Native, Black, Hawaiian/Pacific Islander, Hispanic/Latino, the task force recommends.

Screening tests should include fasting plasma glucose, hemoglobin A1c, or an oral glucose tolerance test. Although screening every 3 years “may be a reasonable approach for adults with normal blood glucose levels,” the task force adds that “the optimal screening interval for adults with an initial normal glucose test result is uncertain.”
 

Data review: Few with prediabetes know they have it

The need for the update was prompted by troubling data showing increasing diabetes rates despite early signs that can and should be identified and acted upon in the primary care setting to prevent disease progression.

Data from the Centers for Disease Control and Prevention, for instance, show that while 13% of all U.S. adults 18 years or older have diabetes and 35% meet criteria for prediabetes, as many as 21% of those with diabetes were not aware of or did not report having the disease. Furthermore, only a small fraction – 15% of those with prediabetes – said they had been told by a health professional that they had this condition, the task force notes.

The task force’s final recommendation was based on a systematic review of evidence regarding the screening of asymptomatic, nonpregnant adults and the harms and benefits of interventions, such as physical activity, behavioral counseling, or pharmacotherapy.

Among key evidence supporting the lower age was a 2014 study showing that the number of people necessary to obtain one positive test for diabetes with screening sharply drops from 80 among those aged 30-34 years to just 31 among those aged 36-39.

Opportunistic universal screening of eligible people aged 35 and older would yield a ratio of 1 out of just 15 to spot a positive test, the authors of that study reported.

In addition, a large cohort study in more than 77,000 people with prediabetes strongly links the risk of developing diabetes with increases in A1c level and with increasing BMI.
 

ADA recommendations differ

The new recommendations differ from American Diabetes Association guidelines, which call for diabetes screening at all ages for people who are overweight or obese and who have one or more risk factors, such as physical inactivity or a first-degree relative with diabetes. If results are normal, repeat screening at least every 3 years is recommended.

The ADA further recommends universal screening for all adults 45 years and older, regardless of their risk factors.

For the screening of adults over 45, the ADA recommends using a fasting plasma glucose level, 2-hour plasma glucose level during a 75-g oral glucose tolerance test, or A1c level, regardless of risk factors.

The American Association of Clinical Endocrinology also recommends universal screening for prediabetes and diabetes for all adults 45 years or older, regardless of risk factors, and also advises screening those who have risk factors for diabetes regardless of age.
 

Screening of little benefit without behavior change support

In an interview, Dr. Grant added that broad efforts are essential as those at the practice level have clearly not succeeded.

“The medical model of individual counseling and referral has not really been effective, and so we really need to think in terms of large-scale public health action,” said Dr. Grant, of the division of research, Kaiser Permanente Northern California, Oakland.

His editorial details the sweeping, multifactorial efforts that are needed.

“To turn this recommendation into action – that is, to translate screening activities into improved clinical outcomes – change is needed at the patient-clinician level (recognizing and encouraging eligible individuals to be screened), health care system level (reducing screening barriers and ensuring access to robust lifestyle programs), and societal level (applying effective public health interventions to reduce obesity and increase exercise),” they write.

A top priority has to be a focus on individuals of diverse backgrounds and issues such as access to healthy programs in minority communities, Dr. Grant noted.

“Newly diagnosed adults are more likely to be African-American and Latinx,” he said.

“We really need to invest in healthier communities for low-income, non-White communities to reverse the persistent health care disparities in these communities.”

While the challenges may appear daunting, history shows they are not necessarily insurmountable – as evidenced in the campaign to discourage tobacco smoking.

“National smoking cessation efforts are one example of a mostly successful public health campaign that has made a difference in health behaviors,” Grant noted.

The recommendation is also posted on the USPSTF web site .

Dr. Grant reports receiving grants from the National Institutes of Health and the Patient-Centered Outcomes Research Institute.

U.S. prescribing data from 160,000 adults with type 2 diabetes and diabetic kidney disease showed a notable uptick in new prescriptions for sodium-glucose cotransporter 2 inhibitors and less dramatic gains for glucagonlike peptide–1 receptor agonists during 2019 and continuing into early 2020, compared with prior years, with usage levels of both classes during the first quarter of 2020 rivaling those of more traditional agents including metformin and insulin.

During the first 3 months of 2020, initiation of a SGLT2 inhibitor constituted 13% of all new starts of an antidiabetes drug among adults with type 2 diabetes and diabetic kidney disease (DKD). This compared with initiation rates during the same early 2020 period of 17% for GLP-1 receptor agonists, 19% for metformin, 16% for sulfonylureas, 15% for insulins, 14% for thiazolidinediones, and 6% for dipeptidyl peptidase–4 inhibitors, the seven drug classes examined in a study published in Diabetes Care.

Early 2020 was the first time that starts of a GLP-1 receptor agonist ranked second (behind only metformin) among these seven drug classes in the studied U.S. population, and early 2020 also marked an unprecedentedly high start rate for SGLT2 inhibitors that nearly tripled the roughly 5% rate in place as recently as 2018.
 

Rises are ‘what we expected’

The recent rise of SGLT2 inhibitors and GLP-1 receptor agonists in these patients “was what we expected,” given the evidence for both classes in slowing progression of DKD, said Julie M. Paik, MD, senior author on the study and a nephrologist and pharmacoepidemiologist at Brigham and Women’s Hospital in Boston.

“We’ve seen other beneficial drugs slow on the uptake, so it’s not surprising to see it here, and I’m optimistic” about further increases going forward, she said in an interview.

Both drug classes “were originally marketed as diabetes drugs,” and it is only since 2019, with the publication of trials showing dramatic renal benefits from canagliflozin (Invokana) in CREDENCE, and from dapagliflozin (Farxiga) in DAPA-CKD in 2020 that the evidence became truly compelling for SGLT2 inhibitors. This evidence also led to new renal-protection indications approved by the Food and Drug Administration for canagliflozin and for dapagliflozin, noted Dr. Paik.

Evidence for renal protection also emerged in 2017 for the GLP-1 receptor agonist liraglutide (Victoza) in the LEADER trial, and for dulaglutide (Trulicity) in the AWARD-7 trial, although neither drug has received a renal indication in its labeling.

By 2020, guidelines for managing patients with type 2 diabetes and chronic kidney disease from the influential Kidney Disease: Improving Global Outcomes organization had identified agents from the SGLT2 inhibitor class as top-tier options, along with metformin, for treating these patients, with agents from the GLP-1 receptor agonist class as the top third class to add in patients who require additional glycemic control.

Additional analyses Dr. Paik and associates ran showed how this played out in terms of which specialists prescribed these drugs during the full period studied beginning in 2013. Throughout this roughly 7-year span, about 70% of the prescriptions written for either SGLT2 inhibitors or for GLP-1 receptor agonists were from internal medicine physicians, followed by about 20% written by endocrinologists. Prescriptions from nephrologists, as well as from cardiologists, have hovered at about 5% each, but seem poised to start rising based on the recently added indications and newer treatment recommendations.

“It’s good to see the recent uptick in use since 2019,” Katherine R. Tuttle, MD, commented in an interview. It’s a positive development for U.S. public health, “but we need to do more to disseminate and implement these life-, kidney-, and heart-saving therapies.”

Future use could approach 80% of DKD patients

Dr. Tuttle estimated that “target” levels of use for SGLT2 inhibitors and for GLP-1 receptor agonists “could reasonably approach 80%” for patients with type 2 diabetes and diabetic kidney disease.

“We will likely move to combination therapy” with simultaneous use of agents from both classes in a targeted way using “precision phenotyping based on clinical characteristics, and eventually perhaps by biomarkers, kidney biopsies, or both.” Combined treatment with both an SGLT2 inhibitor and a GLP-1 receptor agonist may be especially suited to patients with type 2 diabetes, atherosclerotic cardiovascular disease, low estimated glomerular filtration rate, and need for better glycemic control and weight loss, a profile that is “pretty typical” in real-world practice, said Dr. Tuttle, a nephrologist and endocrinologist and executive director for research at Providence Healthcare in Spokane, Wash.
 

Study included patients with commercial or Medicare Advantage coverage

The study used information in an Optum database that included patients enrolled in either commercial or in Medicare Advantage health insurance plans from 2013 to the first quarter of 2020. This included 160,489 adults with type 2 diabetes and DKD who started during that period at least one agent from any of the seven included drug classes.

This focus may have biased the findings because, overall, U.S. coverage of the relatively expensive agents from the SGLT2 inhibitor and GLP-1 receptor agonist classes has often been problematic.

“There are issues of cost, coverage, and access” using these medications, as well as limited data on cost-effectiveness, Dr. Paik acknowledged. Additional issues that have helped generate prescribing lags include concerns about possible adverse effects, low familiarity by providers with these drugs early on, and limited trial experience using them in older patients. The process of clinicians growing more comfortable prescribing these new agents has depended on their “working through the evidence,” she explained.

The FDA’s approval in July 2021 of finerenone (Kerendia) for treating patients with type 2 diabetes and chronic kidney disease threw yet another new variable into the prescribing mix for these patients.

“SGLT2 inhibitors are here to stay as a new standard of care for patients with diabetic kidney disease, but combination with finerenone might be especially useful for patients with diabetic kidney disease and heart failure,” Dr. Tuttle suggested. A new generation of clinical trials will likely soon launch to test these combinations, she predicted.

Dr. Paik had no disclosures. Dr. Tuttle has been a consultant to AstraZeneca, Bayer, Boehringer Ingelheim, Gilead, Goldfinch Bio, Eli Lilly, and Novo Nordisk.

The Food and Drug Administration has granted a biological license application, more commonly known as “full approval,” to the Pfizer-BioNTech COVID-19 vaccine.

It is the first COVID-19 vaccine to be fully licensed in the United States. It will be marketed under the trade name Comirnaty. 

The approval applies to individuals ages 16 years and older. The vaccine is still available for emergency use for those ages 12-15.

The FDA’s stamp of approval is somewhat anticlimactic, following months of real-world use and millions of doses doled out to the general population. It comes after months of scrutiny by the agency of the clinical trial data.

Still, the approval puts the vaccines on firmer legal footing and is expected to spur a raft of new vaccination requirements by employers, schools, and universities. 

“The FDA approval is the gold standard,” President Joe Biden said from the White House. “Those who have been waiting for full approval should go and get your shot now.”

“It could save your life or the lives of those you love,” he said.

Biden also called on businesses to mandate COVID vaccines for their employees.

Indeed, soon after the approval was announced, Defense Secretary Lloyd Austin said the vaccines would be required for all 1.4 million active duty service members.

Public health advocates have seen full approval as an important tool to increase U.S. vaccination rates and had criticized the FDA for taking so long to grant the license.

The presence of chronic kidney disease (CKD) or end-stage renal disease (ESRD) is associated with worse in-hospital and short-term outcomes after left atrial appendage (LAA) closure, a nationwide study shows.

Patients with ESRD were particularly vulnerable, having about 6.5-fold higher odds of in-hospital mortality than those without CKD and about 11.5-fold higher odds than those with CKD, even after adjustment for potential confounders.

Patients with CKD had higher rates of stroke or transient ischemic attack (TIA) and more short-term readmissions for bleeding, Keerat Rai Ahuja, MD, Reading Hospital-Tower Health, West Reading, Pennsylvania, and colleagues reported August 16 in JACC: Cardiovascular Interventions.

CKD and ESRD are known to be associated with an increased risk for stroke and bleeding in patients with atrial fibrillation (AFib), yet data are limited on the safety and efficacy of LAA closure for stroke prevention in AFib patients with CKD or ESRD, they note.  

“It’s important to know about CKD and understand that there may be an association with worse levels of CKD and worse outcomes, but the data that strikes me is really that for end-stage renal disease,” Matthew Sherwood, MD, MHS, who was not involved with the study, said in an interview.

He noted that data have not been published for patients with CKD and ESRD enrolled in the pivotal PROTECT-AF and PREVAIL trials of Boston Scientific’s Watchman device or from large clinical registries such as EWOLUTION and the company’s continued access protocol registries.

Further, it’s not well understood what the best strategy is to prevent stroke in AFib patients with ESRD and whether they benefit from anticoagulation with warfarin or any of the newer agents. “Thus, it’s hard to then say: ‘Well they have worse outcomes with Watchman,’ which is true as shown in this study, but they may not have any other options based upon the lack of data for oral anticoagulants in end-stage kidney disease patients,” said Dr. Sherwood, from the Inova Heart and Vascular Institute, Falls Church, Virginia.

The lack of clarity is concerning, given rising atrial fibrillation cases and the prevalence of abnormal renal function in everyday practice. In the present study – involving 21,274 patients undergoing LAA closure between 2016 and 2017 in the Nationwide Readmissions Database – 18.6% of patients had CKD stages I to V and 2.7% had ESRD based on ICD-10 codes.

In-hospital mortality was increased only in patients with ESRD. In all, 3.3% of patients with ESRD and 0.4% of those with no CKD died in hospital (adjusted odds ratio [aOR], 6.48), as did 0.5% of patients with CKD (aOR, 11.43; both P <.001).

“These patients represent a sicker population at baseline and have an inherent greater risk for mortality in cardiac interventions, as noted in other studies of structural heart interventions,” Dr. Ahuja and colleagues write.

Patients with CKD had a higher risk for in-hospital stroke or TIA than patients with no CKD (1.8% vs. 1.3%; aOR, 1.35; P = .038) and this risk continued up to 90 days after discharge (1.7% vs. 1.0%; aOR, 1.67; P = .007).

The in-hospital stroke rate was numerically higher in patients with ESRD compared with no CKD (aOR, 1.18; P = .62).

The authors point out that previous LAA closure and CKD studies have reported no differences in in-hospital or subsequent stroke/TIA rates in patients with and without CKD. Possible explanations are that patients with CKD in the present study had higher CHA2DS2-VASc scores than those without CKD (4.18 vs. 3.62) and, second, patients with CKD and AFib are known to have higher risk for thromboembolic events than those with AFib without CKD.

CKD patients were also more likely than those without CKD to experience in-hospital acute kidney injury or hemodialysis (aOR, 5.02; P <.001).

CKD has been shown to be independently associated with acute kidney injury (AKI) after LAA closure. AKI may have long-term thromboembolic consequences, the authors suggest, with one study reporting higher stroke risk at midterm follow-up in patients with AKI.

“As with other cardiac interventions in patients with CKD, efforts should be made to optimize preoperative renal function, minimize contrast volume, and avoid abrupt hemodynamic changes such as hypotension during the procedure to prevent AKI,” Dr. Ahuja and colleagues write.

Patients with CKD and ESRD had longer index length of stay than those without CKD but had similar rates of other in-hospital complications, such as systemic embolization, bleeding/transfusion, vascular complications, and pericardial tamponade requiring intervention.

Among the short-term outcomes, 30- and 90-day all-cause readmissions were increased in patients with CKD and ESRD compared with those without CKD, and 30-day bleeding readmissions were increased within the CKD cohort.

“With Watchman and left atrial appendage closure, what we see is that they have higher rates of readmission and other problems,” Dr. Sherwood said. “I think we understand that that’s probably related not to the procedure itself, not because the Watchman doesn’t work for end-stage kidney disease, but because the patients themselves are likely higher risk.”

Commonly used risk scores for atrial fibrillation, however, don’t take into account advanced kidney disease, he added.

Besides the inherent limitations of observational studies, Dr. Sherwood and the authors point to the lack of laboratory variables and procedural variables in the database, the fact that CKD was defined using ICD-10 codes, that outcomes were not clinically adjudicated, that unmeasured confounders likely still exist, and that long-term follow-up is lacking.

Dr. Sherwood, who wrote an editorial accompanying the study, said that the release of outcomes data from CKD and ESRD patients in the major clinical trials would be helpful going forward, as would possible involvement with the Kidney Disease Improving Global Outcomes organization.

“One of the main points of this study is that we just need a lot more research diving into this patient population,” he said.

The presence of chronic kidney disease (CKD) or end-stage renal disease (ESRD) is associated with worse in-hospital and short-term outcomes after left atrial appendage (LAA) closure, a nationwide study shows.

Patients with ESRD were particularly vulnerable, having about 6.5-fold higher odds of in-hospital mortality than those without CKD and about 11.5-fold higher odds than those with CKD, even after adjustment for potential confounders.

Patients with CKD had higher rates of stroke or transient ischemic attack (TIA) and more short-term readmissions for bleeding, Keerat Rai Ahuja, MD, Reading Hospital-Tower Health, West Reading, Pennsylvania, and colleagues reported August 16 in JACC: Cardiovascular Interventions.

CKD and ESRD are known to be associated with an increased risk for stroke and bleeding in patients with atrial fibrillation (AFib), yet data are limited on the safety and efficacy of LAA closure for stroke prevention in AFib patients with CKD or ESRD, they note.  

“It’s important to know about CKD and understand that there may be an association with worse levels of CKD and worse outcomes, but the data that strikes me is really that for end-stage renal disease,” Matthew Sherwood, MD, MHS, who was not involved with the study, said in an interview.

He noted that data have not been published for patients with CKD and ESRD enrolled in the pivotal PROTECT-AF and PREVAIL trials of Boston Scientific’s Watchman device or from large clinical registries such as EWOLUTION and the company’s continued access protocol registries.

Further, it’s not well understood what the best strategy is to prevent stroke in AFib patients with ESRD and whether they benefit from anticoagulation with warfarin or any of the newer agents. “Thus, it’s hard to then say: ‘Well they have worse outcomes with Watchman,’ which is true as shown in this study, but they may not have any other options based upon the lack of data for oral anticoagulants in end-stage kidney disease patients,” said Dr. Sherwood, from the Inova Heart and Vascular Institute, Falls Church, Virginia.

The lack of clarity is concerning, given rising atrial fibrillation cases and the prevalence of abnormal renal function in everyday practice. In the present study – involving 21,274 patients undergoing LAA closure between 2016 and 2017 in the Nationwide Readmissions Database – 18.6% of patients had CKD stages I to V and 2.7% had ESRD based on ICD-10 codes.

In-hospital mortality was increased only in patients with ESRD. In all, 3.3% of patients with ESRD and 0.4% of those with no CKD died in hospital (adjusted odds ratio [aOR], 6.48), as did 0.5% of patients with CKD (aOR, 11.43; both P <.001).

“These patients represent a sicker population at baseline and have an inherent greater risk for mortality in cardiac interventions, as noted in other studies of structural heart interventions,” Dr. Ahuja and colleagues write.

Patients with CKD had a higher risk for in-hospital stroke or TIA than patients with no CKD (1.8% vs. 1.3%; aOR, 1.35; P = .038) and this risk continued up to 90 days after discharge (1.7% vs. 1.0%; aOR, 1.67; P = .007).

The in-hospital stroke rate was numerically higher in patients with ESRD compared with no CKD (aOR, 1.18; P = .62).

The authors point out that previous LAA closure and CKD studies have reported no differences in in-hospital or subsequent stroke/TIA rates in patients with and without CKD. Possible explanations are that patients with CKD in the present study had higher CHA2DS2-VASc scores than those without CKD (4.18 vs. 3.62) and, second, patients with CKD and AFib are known to have higher risk for thromboembolic events than those with AFib without CKD.

CKD patients were also more likely than those without CKD to experience in-hospital acute kidney injury or hemodialysis (aOR, 5.02; P <.001).

CKD has been shown to be independently associated with acute kidney injury (AKI) after LAA closure. AKI may have long-term thromboembolic consequences, the authors suggest, with one study reporting higher stroke risk at midterm follow-up in patients with AKI.

“As with other cardiac interventions in patients with CKD, efforts should be made to optimize preoperative renal function, minimize contrast volume, and avoid abrupt hemodynamic changes such as hypotension during the procedure to prevent AKI,” Dr. Ahuja and colleagues write.

Patients with CKD and ESRD had longer index length of stay than those without CKD but had similar rates of other in-hospital complications, such as systemic embolization, bleeding/transfusion, vascular complications, and pericardial tamponade requiring intervention.

Among the short-term outcomes, 30- and 90-day all-cause readmissions were increased in patients with CKD and ESRD compared with those without CKD, and 30-day bleeding readmissions were increased within the CKD cohort.

Older adults may have a high degree of suicidal intent yet still have low scores on scales measuring psychiatric symptoms, such as depression, new research suggests.

Dobrila Vignjevic/GettyImages

In a cross-sectional cohort study of more than 800 adults who presented with self-harm to psychiatric EDs in Sweden, participants aged 65 years and older scored higher than younger and middle-aged adults on measures of suicidal intent.

However, only half of the older group fulfilled criteria for major depression, compared with three-quarters of both the middle-aged and young adult–aged groups.

“Suicidal older persons show a somewhat different clinical picture with relatively low levels of psychopathology but with high suicide intent compared to younger persons,” lead author Stefan Wiktorsson, PhD, University of Gothenburg (Sweden), said in an interview.

“It is therefore of importance for clinicians to carefully evaluate suicidal thinking in this age group. Safety issues and need for treatment might otherwise be underestimated,” he said.

The findings were published online Aug. 9, 2021, in the American Journal of Geriatric Psychiatry.
 

Research by age groups ‘lacking’

“While there are large age differences in the prevalence of suicidal behavior, research studies that compare symptomatology and diagnostics in different age groups are lacking,” Dr. Wiktorsson said.

He and his colleagues “wanted to compare psychopathology in young, middle-aged, and older adults in order to increase knowledge about potential differences in symptomatology related to suicidal behavior over the life span.”

The researchers recruited patients aged 18 years and older who had sought or had been referred to emergency psychiatric services for self-harm at three psychiatric hospitals in Sweden between April 2012 and March 2016.

Among all patients, 821 fit inclusion criteria and agreed to participate. The researchers excluded participants who had engaged in nonsuicidal self-injury (NNSI), as determined on the basis of the Columbia Suicide Severity Rating Scale (C-SSRS). The remaining 683 participants, who had attempted suicide, were included in the analysis.

The participants were then divided into the following three groups: older (n = 96; age, 65-97 years; mean age, 77.2 years; 57% women), middle-aged (n = 164; age, 45-64 years; mean age, 53.4 years; 57% women), and younger (n = 423; age, 18-44 years; mean age, 28.3 years; 64% women)

Mental health staff interviewed participants within 7 days of the index episode. They collected information about sociodemographics, health, and contact with health care professionals. They used the C-SSRS to identify characteristics of the suicide attempts, and they used the Suicide Intent Scale (SIS) to evaluate circumstances surrounding the suicide attempt, such as active preparation.

Investigators also used the Mini International Neuropsychiatric Interview (MINI), the Suicide Assessment Scale (SUAS), and the Karolinska Affective and Borderline Symptoms Scale.
 

Greater disability, pain

Of the older patients, 75% lived alone; 88% of the middle-aged and 48% of the younger participants lived alone. A higher proportion of older participants had severe physical illness/disability and severe chronic pain compared with younger participants (all comparisons, P < .001).

Older adults had less contact with psychiatric services, but they had more contact than the other age groups with primary care for mental health problems. Older adults were prescribed antidepressants at the time of the suicide attempt at a lower rate, compared with the middle-aged and younger groups (50% vs. 73% and 66%).

Slightly less than half (44%) of the older adults had a previous history of a suicide attempt – a proportion considerably lower than was reported by patients in the middle-aged and young adult groups (63% and 75%, respectively). Few older adults had a history of a previous NNSI (6% vs. 23% and 63%).

Three-quarters of older adults employed poisoning as the single method of suicide attempt at their index episode, compared with 67% and 59% of the middle-aged and younger groups.

Notably, only half of older adults (52%) met criteria for major depression, determined on the basis of the MINI, compared with three quarters of participants in the other groups (73% and 76%, respectively). Fewer members of the older group met criteria for other psychiatric conditions.

Clouded judgment

The mean total SUAS score was “considerably lower” in the older-adult group than in the other groups. This was also the case for the SUAS subscales for affect, bodily states, control, coping, and emotional reactivity.

Importantly, however, older adults scored higher than younger adults on the SIS total score and the subjective subscale, indicating a higher level of suicidal intent.

The mean SIS total score was 17.8 in the older group, 17.4 in the middle-aged group, and 15.9 in the younger group. The SIS subjective suicide intent score was 10.9 versus 10.6 and 9.4.

“While subjective suicidal intent was higher, compared to the young group, older adults were less likely to fulfill criteria for major depression and several other mental disorders and lower scores were observed on all symptom rating scales, compared to both middle-aged and younger adults,” the investigators wrote.

“Low levels of psychopathology may cloud the clinician’s assessment of the serious nature of suicide attempts in older patients,” they added.
 

‘Silent generation’

Commenting on the findings, Marnin Heisel, PhD, CPsych, associate professor, departments of psychiatry and of epidemiology and biostatistics, University of Western Ontario, London, said an important takeaway from the study is that, if health care professionals look only for depression or only consider suicide risk in individuals who present with depression, “they might miss older adults who are contemplating suicide or engaging in suicidal behavior.”

Dr. Heisel, who was not involved with the study, observed that older adults are sometimes called the “silent generation” because they often tend to downplay or underreport depressive symptoms, partially because of having been socialized to “keep things to themselves and not to air emotional laundry.”

He recommended that, when assessing potentially suicidal older adults, clinicians select tools specifically designed for use in this age group, particularly the Geriatric Suicide Ideation Scale and the Geriatric Depression Scale. Dr. Heisel also recommended the Center for Epidemiological Studies Depression Scale–Revised Version.

“Beyond a specific scale, the question is to walk into a clinical encounter with a much broader viewpoint, understand who the client is, where they come from, their attitudes, life experience, and what in their experience is going on, their reason for coming to see someone and what they’re struggling with,” he said.

“What we’re seeing with this study is that standard clinical tools don’t necessarily identify some of these richer issues that might contribute to emotional pain, so sometimes the best way to go is a broader clinical interview with a humanistic perspective,” Dr. Heisel concluded.

The study was funded by the Swedish Research Council, the Swedish Research Council for Health, Working Life and Welfare, and the Swedish state, Stockholm County Council and Västerbotten County Council. The investigators and Dr. Heisel have reported no relevant financial relationships.

Commenting on the findings, Marnin Heisel, PhD, CPsych, associate professor, departments of psychiatry and of epidemiology and biostatistics, University of Western Ontario, London, said an important takeaway from the study is that, if health care professionals look only for depression or only consider suicide risk in individuals who present with depression, “they might miss older adults who are contemplating suicide or engaging in suicidal behavior.”

Dr. Heisel, who was not involved with the study, observed that older adults are sometimes called the “silent generation” because they often tend to downplay or underreport depressive symptoms, partially because of having been socialized to “keep things to themselves and not to air emotional laundry.”

He recommended that, when assessing potentially suicidal older adults, clinicians select tools specifically designed for use in this age group, particularly the Geriatric Suicide Ideation Scale and the Geriatric Depression Scale. Dr. Heisel also recommended the Center for Epidemiological Studies Depression Scale–Revised Version.

“Beyond a specific scale, the question is to walk into a clinical encounter with a much broader viewpoint, understand who the client is, where they come from, their attitudes, life experience, and what in their experience is going on, their reason for coming to see someone and what they’re struggling with,” he said.

“What we’re seeing with this study is that standard clinical tools don’t necessarily identify some of these richer issues that might contribute to emotional pain, so sometimes the best way to go is a broader clinical interview with a humanistic perspective,” Dr. Heisel concluded.

The study was funded by the Swedish Research Council, the Swedish Research Council for Health, Working Life and Welfare, and the Swedish state, Stockholm County Council and Västerbotten County Council. The investigators and Dr. Heisel have reported no relevant financial relationships.

Tweets from a black female medical student about the perils of being on call after lengthy hospital shifts was met with a stinging rebuke from the Twitter account of the Connecticut chapter of the American College of Cardiology – prompting an apology and some high-octane exchanges on medical Twitter.

In a series of Tweets, “queen of anonymous medicine” @QueenMD202X describes one friend “working 87 hours this week and 13 days straight” and a second, a third-year medical student working a 15-hour surgical shift. “That is cruel,” she writes, “15-hour shift? For what?????”

In response to a Tweet suggesting that being on call can be a valuable experience for students to know what they’re facing once they get to residency, @QueenMD202X pointed out the 15-hour shifts aren’t just a one-off.

In a now-deleted Tweet that nevertheless appears in several additional tweets as a screenshot, @ConnecticutACC replied: “You might be in the wrong field. You sound very angry probably unsuitable for patient care when your mental state is as you describe it. Emotions are contagious.”

The response from the medical and broader Twitter community was swift, with several tweets calling the chapter’s reply insensitive and racist.

In another Tweet, @BrittGratreak responded by stating: “I think institutions need to be more transparent how they basically weigh the costs & benefits of writing a memorial statement for students who die by suicide rather than investing in changing the toxic culture of medical education to prevent deaths & producing harmed physicians.”

Within hours, Connecticut-ACC issued an apology from their now-deleted account and questioned the origins of the Tweet. “We sincerely apologize for the earlier post as the views do not represent the values or beliefs of the Chapter or broader ACC. We are working to ID its origins. Burnout & well-being are critical issues [that] ACC/CCACC is working to address on behalf of members at all career stages.”

Speaking to this news organization, Connecticut-ACC president and governor Craig McPherson, MD, Yale University, New Haven, Conn., said the chapter believes its account was hacked.

“We provide limited password access to our Twitter account, and we assume, since we’ve contacted most of the individuals who had access to the current password and all of the them deny any knowledge, the account got hacked … it’s just one of those unfortunate aspects of social media,” he said.

The password was quickly changed after the chapter learned of the Tweet on Wednesday and the account has since been closed, at Dr. McPherson’s request.

“We don’t condone that kind of language, that kind of remark. It’s highly inappropriate, and I certainly agree with anyone that voiced that opinion in the Twitterstorm that followed,” he said. “But as I said at the outset, I have no control over what people say on social media once it’s out there. All we can do is apologize for the fact our Twitter feed was used as a vehicle for those comments, which we consider inappropriate.”

Asked whether he considered the remarks racist, Dr. McPherson replied: “That’s not for me to judge.”

ACC president Dipti Itchhaporia, MD, however, weighed in this afternoon with a Tweet citing the need to address clinician well-being and an inclusive workplace.

Some on Twitter recalled their own long hours as a medical student or defended the need to inculcate students in the long hours they’ll face as physicians. Others observed that neither ACC nor its Connecticut chapter addressed the issue of medical student hours in their response. Although fellow and resident hours are regulated, Dr. McPherson pointed out that it’s up to each individual medical school to set the hours for their students.
