Changes in hormones, body composition, lipids, and vascular health during the menopause transition can increase a woman’s chance of developing cardiovascular disease (CVD) after menopause, the American Heart Association said in a scientific statement.

“This statement aims to raise awareness of both healthcare providers and women about the menopause transition as a time of increasing heart disease risk,” Samar R. El Khoudary, PhD, MPH, who chaired the writing group, said in an interview.

“As such, it emphasizes the importance of monitoring women’s health during midlife and targeting this stage as a critical window for applying early intervention strategies that aim to maintain a healthy heart and reduce the risk of heart disease,” said Dr. El Khoudary, of the University of Pittsburgh.

The statement was published online Nov. 30 in Circulation.
 

Evolution in knowledge

During the past 20 years, knowledge of how menopause might contribute to CVD has evolved “dramatically,” Dr. El Khoudary noted. The accumulated data consistently point to the menopause transition as a time of change in heart health.

“Importantly,” she said, the latest AHA guidelines for CVD prevention in women, published in 2011, do not include data now available on the menopause transition as a time of increased CVD risk.

“As such, there is a compelling need to discuss the implications of the accumulating body of literature on this topic,” said Dr. El Khoudary.

The statement provides a contemporary synthesis of the existing data on menopause and how it relates to CVD, the leading cause of death of U.S. women.

Earlier age at natural menopause has generally been found to be a marker of greater CVD risk. Iatrogenically induced menopause (bilateral oophorectomy) during the premenopausal period is also associated with higher CVD risk, the data suggest.

Vasomotor symptoms are associated with worse levels of CVD risk factors and measures of subclinical atherosclerosis. Sleep disturbance has also been linked to greater risk for subclinical CVD and worse CV health indexes in women during midlife.

Increases in central/visceral fat and decreases in lean muscle mass are more pronounced during the menopause transition. This increased central adiposity is associated with increased risk for mortality, even among those with normal body mass index, the writing group found.

Increases in lipid levels (LDL cholesterol and apolipoprotein B), metabolic syndrome risk, and vascular remodeling at midlife are driven by the menopause transition more than aging, whereas increases in blood pressure, insulin level, and glucose level are likely more influenced by chronological aging, they reported.
 

Lifestyle interventions

The writing group noted that, because of the increase in overall life expectancy in the United States, a significant proportion of women will spend up to 40% of their lives after menopause.

Yet data suggest that only 7.2% of women transitioning to menopause are meeting physical activity guidelines and that fewer than 20% of those women are consistently maintaining a healthy diet.

Limited data from randomized, controlled trials suggest that a multidimensional lifestyle intervention during the menopause transition can prevent weight gain and reduce blood pressure and levels of triglycerides, blood glucose, and insulin and reduce the incidence of subclinical carotid atherosclerosis, they pointed out.

“Novel data” indicate a reversal in the associations of HDL cholesterol with CVD risk over the menopause transition, suggesting that higher HDL cholesterol levels may not consistently reflect good cardiovascular health in middle-aged women, the group noted.

There are also data suggesting that starting menopause hormone therapy when younger than 60 years or within 10 years of menopause is associated with reduced CVD risk.

The group said further research is needed into the cardiometabolic effects of menopause hormone therapy, including effects associated with form, route, and duration of administration, in women traversing menopause.

They also noted that data for the primary and secondary prevention of atherosclerotic CVD and improved survival with lipid-lowering interventions “remain elusive” for women and that further study is needed to develop evidence-based recommendations tailored specifically to women.

The research had no commercial funding. Dr. El Khoudary has disclosed no relevant financial relationships.

As an increasing number of health systems implement “hospital-at-home” (HaH) programs to increase their traditional hospital capacity, the Centers for Medicare & Medicaid Services has given the movement a boost by changing its regulations to allow acute care to be provided in a patient’s home under certain conditions.

The CMS announced Nov. 25 that it was launching its Acute Hospital Care at Home program “to increase the capacity of the American health care system” during the COVID-19 pandemic.

At the same time, the agency announced it was giving more flexibility to ambulatory surgery centers (ASCs) to provide hospital-level care.

The CMS said its new HaH program is an expansion of the Hospitals Without Walls initiative that was unveiled last March. Hospitals Without Walls is a set of “temporary new rules” that provide flexibility for hospitals to provide acute care outside of inpatient settings. Under those rules, hospitals are able to transfer patients to outside facilities, such as ASCs, inpatient rehabilitation hospitals, hotels, and dormitories, while still receiving Medicare hospital payments.

Under CMS’ new Acute Hospital Care at Home, which is not described as temporary, patients can be transferred from emergency departments or inpatient wards to hospital-level care at home. The CMS said the HaH program is designed for people with conditions such as the acute phases of asthma, heart failure, pneumonia, and chronic obstructive pulmonary disease. Altogether, the agency said, more than 60 acute conditions can be treated safely at home.

However, the agency didn’t say that facilities can’t admit COVID-19 patients to the hospital at home. Rami Karjian, MBA, cofounder and CEO of Medically Home, a firm that supplies health systems with technical services and software for HaH programs, said in an interview that several Medically Home clients plan to treat both COVID-19 and non-COVID-19 patients at home when they begin to participate in the CMS program in the near future.

The CMS said it consulted extensively with academic and private industry leaders in building its HaH program. Before rolling out the initiative, the agency noted, it conducted successful pilot programs in leading hospitals and health systems. The results of some of these pilots have been reported in academic journals.

Participating hospitals will be required to have specified screening protocols in place before beginning acute care at home, the CMS announced. An in-person physician evaluation will be required before starting care at home. A nurse will evaluate each patient once daily in person or remotely, and either nurses or paramedics will visit the patient in person twice a day.

In contrast, Medicare regulations require nursing staff to be available around the clock in traditional hospitals. So the CMS has to grant waivers to hospitals for HaH programs.

While not going into detail on the telemonitoring capabilities that will be required in the acute hospital care at home, the release said, “Today’s announcement builds upon the critical work by CMS to expand telehealth coverage to keep beneficiaries safe and prevent the spread of COVID-19.”
 

More flexibility for ASCs

The agency is also giving ASCs the flexibility to provide 24-hour nursing services only when one or more patients are receiving care on site. This flexibility will be available to any of the 5,700 ASCs that wish to participate, and will be immediately effective for the 85 ASCs currently participating in the Hospital Without Walls initiative, the CMS said.

The new ASC regulations, the CMS said, are aimed at allowing communities “to maintain surgical capacity and other life-saving non-COVID-19 [care], like cancer surgeries.” Patients who need such procedures will be able to receive them in ASCs without being exposed to known COVID-19 cases.

Similarly, the CMS said patients and families not diagnosed with COVID-19 may prefer to receive acute care at home if local hospitals are full of COVID-19 patients. In addition, the CMS said it anticipates patients may value the ability to be treated at home without the visitation restrictions of hospitals.
 

Early HaH participants

Six health systems with extensive experience in providing acute hospital care at home have been approved for the new HaH waivers from Medicare rules. They include Brigham and Women’s Hospital (Massachusetts); Huntsman Cancer Institute (Utah); Massachusetts General Hospital (Massachusetts); Mount Sinai Health System (New York City); Presbyterian Healthcare Services (New Mexico); and UnityPoint Health (Iowa).

The CMS said that it’s in discussions with other health care systems and expects new applications to be submitted soon.

To support these efforts, the CMS has launched an online portal to streamline the waiver request process. The agency said it will closely monitor the program to safeguard beneficiaries and will require participating hospitals to report quality and safety data on a regular basis.
 

Support from hospitals

The first health systems participating in the CMS HaH appear to be supportive of the program, with some hospital leaders submitting comments to the CMS about their view of the initiative.

“The CMS has taken an extraordinary step today, facilitating the rapid expansion of Hospitalization at Home, an innovative care model with proven results,” said Kenneth L. Davis, MD, president and CEO of the Mount Sinai Health System in New York City. “This important and timely move will enable hospitals across the country to use effective tools to safely care for patients during this pandemic.”

David Levine, MD, assistant professor of medicine and medical director of strategy and innovation for Brigham Health Home Hospital in Boston, was similarly laudatory: “Our research at Brigham Health Home has shown that we can deliver hospital-level care in our patients’ homes with lower readmission rates, more physical mobility, and a positive patient experience,” he said. “During these challenging times, a focus on the home is critical. We are so encouraged that CMS is taking this important step, which will allow hospitals across the country to increase their capacity while delivering the care all patients deserve.”
 

Scaling up quickly

If other hospitals and health systems recognize the value of HaH, how long might it take them to develop and implement these programs in the midst of a pandemic?

Atrium Health, a large health system in the Southeast, ramped up a hospital-at-home initiative last spring for its 10 hospitals in the Charlotte, N.C., area, in just 2 weeks. However, it had been working on the project for some time before the pandemic struck. Focusing mostly on COVID-19 patients, the initiative reduced the COVID-19 patient load by 20%-25% in Atrium’s hospitals.

Medically Home, the HaH infrastructure company, said in a news release that it “enables health systems to establish new hospital-at-home services in as little as 30 days.” Medically Home has partnered in this venture with Huron Consulting Group, which has about 200 HaH-trained consultants, and Cardinal Health, a large global medical supplies distributor.

Mr. Karjian said in an interview that he expects private insurers to follow CMS’ example, as they often do. “We think this decision will cause not only CMS but private insurers to cover hospital at home after the pandemic, if it becomes the standard of care, because patients have better outcomes when treated at home,” he said.

Asked for his view on why the CMS specified that patients could be admitted to an HaH only from emergency departments or inpatient settings, Mr. Karjian said that the CMS wants to make sure that patients have access to brick-and-mortar hospital care if that’s what they need. Also, he noted, this model is new to most hospitals, so the CMS wants to make sure it starts “with all the safety guardrails” in place.

Overall, Mr. Karjian said, “This is an exciting development for patients across the country. What CMS has done is terrific in terms of letting patients get the care they want, where they want it, and get the benefit of better outcomes while the nation is going through this capacity crunch for hospital beds.”

Background: Heart failure is a known risk factor for postoperative mortality and complications. Many of the studies used to establish this association, however, have focused on major high-risk surgeries and not on outpatient surgeries. Improved medical care has increased the survival rate of patients with heart failure and an increasing number of these patients are undergoing elective surgical procedures. This has led to an increasing need to better understand the degree to which heart failure affects preoperative risk in the outpatient setting.

Study design: A retrospective cohort study.

Setting: Multiple Veteran’s Affairs Hospitals using data from the VA Surgical Quality Improvement Program (VASQIP) and the VA Corporate Data Warehouse.

Synopsis: A total of 355,121 patients who underwent outpatient surgeries were analyzed. 19,353 patients had heart failure and 334,768 did not. Patients with heart failure had a higher risk of 90-day mortality with an adjusted odds ratio of 1.95 (95% confidence interval, 1.69-2.44), and this risk progressively increased as the ejection fraction decreased. The risk of 30-day complication also increased in patients with heart failure with an adjusted OR of 1.10 (95% CI, 1.02-1.19).

Limitations of this study include the patient population, which were all veterans and mostly male. The nature of the inclusion criteria was limiting as well, in that all the patients in this study were deemed fit for surgery. There were no data available for patients who had been considered but ultimately did not undergo surgery or for patients who were considered for ambulatory surgery but ultimately underwent inpatient surgery. These limitations may have resulted in a selection bias, which limited the generalizability of the study’s findings when assessing patients for ambulatory surgery.

Bottom line: Patients with heart failure had a higher risk of 90-day postoperative mortality and 30-day postoperative complication in ambulatory noncardiac surgery. The risk of postoperative mortality increased as systolic function decreased.

Background: Heart failure is a known risk factor for postoperative mortality and complications. Many of the studies used to establish this association, however, have focused on major high-risk surgeries and not on outpatient surgeries. Improved medical care has increased the survival rate of patients with heart failure and an increasing number of these patients are undergoing elective surgical procedures. This has led to an increasing need to better understand the degree to which heart failure affects preoperative risk in the outpatient setting.

Study design: A retrospective cohort study.

Hyperglycemia at hospital admission – regardless of diabetes status – is a key predictor of COVID-19-related death and severity among noncritical patients, new research from Spain finds.

The observational study, the largest to date to investigate this association, was published online Nov. 23 in Annals of Medicine by Francisco Javier Carrasco-Sánchez, MD, PhD, and colleagues.

Among more than 11,000 patients with confirmed COVID-19 from March to May 2020 in a nationwide Spanish registry involving 109 hospitals, admission hyperglycemia independently predicted progression from noncritical to critical condition and death, regardless of prior diabetes history. 

Those with abnormally high glucose levels were more than twice as likely to die from the virus than those with normal readings (41.4% vs 15.7%). They also had an increased need for a ventilator and intensive care unit (ICU) admission.

“These results provided a simple and practical way to stratify risk of death in hospitalized patients with COVID-19. Hence, admission hyperglycemia should not be overlooked, but rather detected and appropriately treated to improve the outcomes of COVID-19 patients with and without diabetes,” Dr. Carrasco-Sánchez and colleagues wrote.

The findings confirm those of previous retrospective observational studies, but the current study “has, by far, the biggest number of patients involved in this kind of study [to date]. All conclusions are consistent to other studies,” Dr. Carrasco-Sánchez, of University Hospital Juan Ramón Jiménez, Huelva, Spain, said in an interview.

However, a surprising finding, he said, “was how hyperglycemia works in the nondiabetic population and [that] glucose levels over 140 [mg/dL] ... increase the risk of death.”
 

Pay attention to even mild hyperglycemia from admission

The study also differs from some of the prior observational ones in that it examines outcome by admission glycemia rather than during the hospital stay, therefore eliminating the effect of any inpatient treatment, such as dexamethasone, he noted.

Although blood glucose measurement at admission is routine for all patients in Spain, as it is in the United States and elsewhere, a mildly elevated level in a person without a diagnosis of diabetes may not be recognized as important.

“In patients with diabetes we start the protocol to control and treat hyperglycemia during hospitalization. However, in nondiabetic patients blood glucose levels under 180 [mg/dL], and even greater, are usually overlooked. This means there is not a correct follow-up of the patients during hospitalization.

“After this study we learned that we need to pay attention to this population ... who develop hyperglycemia from the beginning,” he said.  

The study was limited in that patients who had previously undiagnosed diabetes couldn’t always be distinguished from those with acute “stress hyperglycemia.”

However, both need to be managed during hospitalization, he said. “Unfortunately, there is high variability in inpatient glucose management. The working group of diabetes of the Spanish Society of Internal Medicine is working on specific protocols,” said Dr. Carrasco-Sánchez.
 

All-cause death, progress to critical care higher with hyperglycemia

The retrospective, multicenter study was based on data from 11,312 adult patients with confirmed COVID-19 in 109 hospitals participating in Spain’s SEMI-COVID-19 registry as of May 29, 2020. They had a mean age of 67 years, 57% were male, and 19% had a diagnosis of diabetes. A total of 20% (n = 2,289) died during hospitalization.

Overall all-cause mortality was 41.1% among those with admission blood glucose levels above 180 mg/dL, 33.0% for those with glucose levels 140-180 mg/dL, and 15.7% for levels below 140 mg/dL. All differences were significant (P < .0001), but there were no differences in mortality rates within each blood glucose category between patients with or without a previous diagnosis of diabetes.

After adjustment for confounding factors, elevated admission blood glucose level remained a significant predictor of death. Compared to < 140 mg/dL, the hazard ratios for 140-180 mg/dL and > 180 mg/dL were 1.48 and 1.50, respectively (both P < .001). (Adjustments included age, gender, hypertension, diabetes, chronic obstructive pulmonary disease, lymphopenia, anemia (hemoglobin < 10 g/dL), serum creatinine, C-reactive protein > 60 mg/L, lactate dehydrogenase > 400 U/L and D-dimer >1000 ng/mL.)

Length of stay was 12, 11.5, and 11.1 days for those with admission blood glucose levels > 180, 140-180, and < 140 mg/dL, respectively (P = .011).

Use of mechanical ventilation and admission to intensive care also rose with higher admission blood glucose levels. For the composite of death, mechanical ventilation, and/or ICU admission, odds ratios for 140-180 mg/dL and > 180 mg/dL compared with < 140 mg/dL were 1.70 and 2.02, respectively (both P < .001). 

The study was supported by the Spanish Federation of Internal Medicine. The authors have reported no relevant financial relationships.

The interventional cardiology community is mourning the loss of Anthony “Tony” Gershlick, MBBS, who died Nov. 20 of COVID-19. He was 69 years old.

Dr. Gershlick was a “talented, dedicated and much loved colleague,” reads a statement issued by the University of Leicester (England), where he was affiliated for more than 3 decades.

Dr. Gershlick, a consultant cardiologist at Glenfield Hospital and professor of interventional cardiology, University of Leicester, passed away in the intensive care unit of the hospital where he worked.

Nishan Canagarajah, PhD, president and vice-chancellor, University of Leicester, said Dr. Gershlick “left an indelible mark on the life of the University. He will be remembered with great affection by all and will be sorely missed.”

In 2017, Dr. Gershlick was honored with the inaugural British Cardiovascular Intervention Society (BCIS) Lifetime Achievement Career Award for his “outstanding contribution to the specialty of coronary intervention.”

Gershlick was a pioneer in the field of percutaneous coronary intervention. He was the first UK cardiologist to implant a drug-eluting stent and a bioabsorbable stent, according to an article in the European Heart Journal.

Throughout his career, Dr. Gershlick had been involved in “practice-changing” research that changed the way patients are treated and led to national and international guidelines. He was the UK lead for more than 10 international trials, the university said.

“Tony was determined to push the boundaries of clinical care, to make a difference for his patients, and indeed, patients around the world,” said Philip Baker, DM, FMedSci, head of the College of Life Science, University of Leicester.

Andrew Furlong, medical director at the University Hospitals of Leicester, noted that Dr. Gershlick was “deeply committed to the training and development of junior doctors and registrars and known for his dedication to his field and his patients. He made a difference to many, many lives.”

According to the university, Dr. Gershlick had been working in non-COVID environments since April and was doing much of his work via virtual consultations. He took on cases from other consultants to help during the pandemic and had been working “tirelessly” to provide continuing care to cardiology patients.

The news of Dr. Gershlick’s passing prompted an outpouring of sadness and remembrances of him on Twitter.

Lowering blood pressure for patients with intracerebral hemorrhage (ICH) does not improve functional recovery, a systematic review and meta-analysis shows, although it does reduce hematoma growth in these patients.

Despite the negative finding, the investigators observed broad variation in treatment effect among the studies they reviewed. They also found that target-based blood pressure treatment tended to improve function more than fixed-dose treatment.

“These data provide a strong message that early blood pressure–lowering treatment can control bleeding. This was not clear beforehand,” Craig Anderson, PhD, professor of neurology and epidemiology at the University of New South Wales, Sydney, said in an interview.

“But these data also indicate that the management of blood pressure in ICH is complex,” he added. Timing, type of drug, and type of patient must be considered, he said. “We need more data to allow better individualizing of such therapy.”

The results were presented at the European Stroke Organisation–World Stroke Organisation (ESO-WSO) Conference 2020.

Controversy about the efficacy of blood pressure reduction for patients with ICH continues, despite studies that have examined this question. In this analysis, Dr. Anderson and colleagues sought to examine the evidence from randomized controlled trials in this area and identify potentially overlooked heterogeneity among trials.

The investigators conducted a systematic review and meta-analysis of studies in the Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE databases. They searched for randomized controlled trials of blood pressure management for adults with acute ICH, focusing on studies in which patients were enrolled within 7 days of ICH onset. These studies compared intensive blood pressure management with guideline-based management.

Investigators chose function, defined as Modified Rankin Scale (mRS) score at 90 days, as their primary outcome. Radiologic outcomes included absolute (>6 mL) and proportional (>33%) hematoma growth at 24 hours. They used the intention to treat dataset from each trial in their statistical analyses and created generalized linear mixed models with prespecified covariables using a one-stage approach.
 

Variation by drug

A total of 7,094 studies were identified, of which 50 were eligible for inclusion. Their analysis encompassed 16 studies for which the respective investigators were willing to share patient-level data. The analysis included data on 6,221 patients. The mean age of the patients was 64.2 years, 36.4% were women, and the median time from symptom onset to randomization was 3.8 hours.

Mean National Institutes of Health Stroke Scale score was approximately 11. Mean systolic blood pressure at baseline was 177 mm Hg, and mean hematoma volume was approximately 10.6 mL.

The difference in blood pressure between the intensive and guideline groups was approximately 8 mm Hg at 1 hour and 12 mm Hg at 24 hours.

Intensive blood pressure management did not affect function at 90 days. The adjusted odds ratio for unfavorable shift in mRS scores was 0.97 (95% CI, 0.88-1.06; P = .503). Intensive blood pressure management did, however, reduce hematoma growth (absolute aOR, 0.75; 95% CI, 0.60-0.92; P = .007; relative aOR, 0.82; 95% CI, 0.68-0.99; P = .034).

In prespecified subgroup analyses, they found a trend toward adverse outcomes among patients who received renin-angiotensin blockers and a trend toward benefit for patients who received alpha- or beta-receptor antagonists or calcium channel blockers. They did not observe a clear association between time of treatment and outcome.

In addition to hematoma growth, other factors influence prognosis after ICH, such as the patient’s status before ICH (for example, cardiovascular risk factors, age, and hypertensive effects on the brain, kidneys, and heart), the location of ICH and its effects on surrounding structures, and complications of care in hospitals, such as infection and bleeding, said Dr. Anderson.

They are conducting two ongoing clinical trials in patients with ICH. One, INTERACT3, is evaluating a “care bundle” quality control package that includes early intensive blood pressure lowering for patients with large ICH who undergo surgery.

The other, INTERACT4, is evaluating early blood pressure control in the ambulance for patients with suspected acute stroke. At least one-fifth of those patients will have ICH, said Dr. Anderson.
 

Prevention is essential

Among patients with ICH, much of the bleeding occurs before presentation at the hospital, Louis R. Caplan, MD, a neurologist at Beth Israel Deaconess Medical Center, Boston, said in an interview. Furthermore, the bleeding mainly occurs in the deep part of the brain where most of the important motor tracts are. “If those tracts are already hit, a little extra blood isn’t going to change things,” said Dr. Caplan, who was not involved in the research.

In addition, blood is pushed from inside the brain to the periphery until the pressure outside the brain is equal to the pressure inside it. “You can decrease the amount of bleeding significantly, but it probably doesn’t affect the outcome,” said Dr. Caplan.

One factor in patients’ apparent lack of functional improvement is that the mRS is not sensitive to minor changes in disability, he said. “You have to show a pretty important change for it to make a difference,” said Dr. Caplan.

In addition, recovery from a hemorrhage takes much longer than recovery from an infarct. Examining the population at 6 months would have been preferable to examining them at 90 days, but the investigators might not have 6-month data, said Dr. Caplan.

“The main thing is really prevention,” he concluded.

The study was conducted with funding from Takeda. Dr. Anderson reported receiving funding from the National Health and Medical Research Council of Australia and speaker fees from Takeda. Dr. Caplan has disclosed no relevant financial relationships.

Lowering blood pressure for patients with intracerebral hemorrhage (ICH) does not improve functional recovery, a systematic review and meta-analysis shows, although it does reduce hematoma growth in these patients.

Despite the negative finding, the investigators observed broad variation in treatment effect among the studies they reviewed. They also found that target-based blood pressure treatment tended to improve function more than fixed-dose treatment.

“These data provide a strong message that early blood pressure–lowering treatment can control bleeding. This was not clear beforehand,” Craig Anderson, PhD, professor of neurology and epidemiology at the University of New South Wales, Sydney, said in an interview.

“But these data also indicate that the management of blood pressure in ICH is complex,” he added. Timing, type of drug, and type of patient must be considered, he said. “We need more data to allow better individualizing of such therapy.”

The results were presented at the European Stroke Organisation–World Stroke Organisation (ESO-WSO) Conference 2020.

Controversy about the efficacy of blood pressure reduction for patients with ICH continues, despite studies that have examined this question. In this analysis, Dr. Anderson and colleagues sought to examine the evidence from randomized controlled trials in this area and identify potentially overlooked heterogeneity among trials.

The investigators conducted a systematic review and meta-analysis of studies in the Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE databases. They searched for randomized controlled trials of blood pressure management for adults with acute ICH, focusing on studies in which patients were enrolled within 7 days of ICH onset. These studies compared intensive blood pressure management with guideline-based management.

Investigators chose function, defined as Modified Rankin Scale (mRS) score at 90 days, as their primary outcome. Radiologic outcomes included absolute (>6 mL) and proportional (>33%) hematoma growth at 24 hours. They used the intention to treat dataset from each trial in their statistical analyses and created generalized linear mixed models with prespecified covariables using a one-stage approach.
 

Variation by drug

A total of 7,094 studies were identified, of which 50 were eligible for inclusion. Their analysis encompassed 16 studies for which the respective investigators were willing to share patient-level data. The analysis included data on 6,221 patients. The mean age of the patients was 64.2 years, 36.4% were women, and the median time from symptom onset to randomization was 3.8 hours.

Mean National Institutes of Health Stroke Scale score was approximately 11. Mean systolic blood pressure at baseline was 177 mm Hg, and mean hematoma volume was approximately 10.6 mL.

The difference in blood pressure between the intensive and guideline groups was approximately 8 mm Hg at 1 hour and 12 mm Hg at 24 hours.

Intensive blood pressure management did not affect function at 90 days. The adjusted odds ratio for unfavorable shift in mRS scores was 0.97 (95% CI, 0.88-1.06; P = .503). Intensive blood pressure management did, however, reduce hematoma growth (absolute aOR, 0.75; 95% CI, 0.60-0.92; P = .007; relative aOR, 0.82; 95% CI, 0.68-0.99; P = .034).

In prespecified subgroup analyses, they found a trend toward adverse outcomes among patients who received renin-angiotensin blockers and a trend toward benefit for patients who received alpha- or beta-receptor antagonists or calcium channel blockers. They did not observe a clear association between time of treatment and outcome.

In addition to hematoma growth, other factors influence prognosis after ICH, such as the patient’s status before ICH (for example, cardiovascular risk factors, age, and hypertensive effects on the brain, kidneys, and heart), the location of ICH and its effects on surrounding structures, and complications of care in hospitals, such as infection and bleeding, said Dr. Anderson.

They are conducting two ongoing clinical trials in patients with ICH. One, INTERACT3, is evaluating a “care bundle” quality control package that includes early intensive blood pressure lowering for patients with large ICH who undergo surgery.

The other, INTERACT4, is evaluating early blood pressure control in the ambulance for patients with suspected acute stroke. At least one-fifth of those patients will have ICH, said Dr. Anderson.
 

Prevention is essential

Among patients with ICH, much of the bleeding occurs before presentation at the hospital, Louis R. Caplan, MD, a neurologist at Beth Israel Deaconess Medical Center, Boston, said in an interview. Furthermore, the bleeding mainly occurs in the deep part of the brain where most of the important motor tracts are. “If those tracts are already hit, a little extra blood isn’t going to change things,” said Dr. Caplan, who was not involved in the research.

Contrary to historical evidence, among older people, elevated LDL cholesterol levels increase risk for heart attack and cardiovascular disease, and older patients benefit as much, if not more, from statins and other cholesterol-lowering drugs than do younger people, two new studies show.

“By contrast with previous historical studies, our data show that LDL cholesterol is an important risk factor for myocardial infarction and atherosclerotic cardiovascular disease in a contemporary primary prevention cohort of individuals aged 70 to 100 years,” Borge Nordestgaard, MD, of the University of Copenhagen, and colleagues noted in the first of the two studies, published this week in the Lancet.

“By lowering LDL cholesterol in healthy individuals aged 70-100 years, the potential for preventing myocardial infarctions and atherosclerotic cardiovascular disease is huge, and at a substantially lower number needed to treat when compared with those aged 20-69 years,” they added.

“These findings support the concept of the cumulative burden of LDL cholesterol over one’s lifetime and the progressive increase in risk for atherosclerotic cardiovascular disease, including myocardial infarction, with age,” added Frederick J. Raal, PhD, and Farzahna Mohamed, MB BCh, of the University of the Witwatersrand, Johannesburg, South Africa, in an editorial published with both new studies in the Lancet (2020 Nov 10. doi: 10.1016/S0140-6736[20]32333-3).

The studies underscore the need for clinicians to consider continued risks associated with elevated LDL cholesterol in older age, they stressed, adding that statins are also beneficial for younger persons at risk to prevent conditions from worsening.

“The average age of patients in all the trials analyzed was older than 60 years, an age when atherosclerotic cardiovascular disease is already well established,” the editorialists wrote.

“Lipid-lowering therapy should be initiated at a younger age, preferably before age 40 years, in those at risk to delay the onset of atherosclerosis, rather than try to manage the condition once fully established or advanced,” they stressed.
 

No RCTs have included patients older than 70

For persons aged 40-75 years, elevated LDL cholesterol levels are a known risk factor for MI and atherosclerotic cardiovascular disease, and there is consensus in guidelines regarding treatment with statins.

However, the risk for people older than 70 is controversial. Some studies show little or no association between elevated LDL cholesterol levels and an increased risk for MI.

Contributing to the uncertainty is that few of the randomized, controlled trials that have investigated the question have included patients aged older than 70 years.

As a consequence, many practice guidelines have noted that the level of evidence in older patients is low, and some organizations have lowered the strength of recommendations regarding the treatment for older patients in comparison with younger patients.
 

Primary prevention: CV events increase with elevated LDL cholesterol in older age

Dr. Nordestgaard and colleagues studied data on 91,131 people living in Copenhagen who did not have atherosclerotic cardiovascular disease or diabetes at baseline and were not taking statins.

Of the participants, 10,592 were aged 70-79 years, and 3,188 participants were aged 80-100 years.

Over an average follow-up period of 7.7 years, 1,515 participants had a first MI, and 3,389 developed atherosclerotic cardiovascular disease.

In the primary-prevention cohort, after multivariate adjustment, the risk of having a heart attack per 1.0 mmol/L increase in LDL cholesterol was increased in the group overall (hazard ratio, 1.34). The increased risk was observed for all age groups, including those aged 80-100 years (HR, 1.28), 70-79 (HR, 1.25), 60-69 (HR, 1.29), 50-59 (HR, 1.28), and 20-49 (HR, 1.68).

Risk for atherosclerotic cardiovascular disease was also raised per 1.0 mmol/L increase in LDL cholesterol overall (HR, 1.16) and in all age groups, particularly those aged 70-100 years.

Greater elevations in LDL cholesterol (5.0 mmol/L or higher, indicative of possible familial hypercholesterolemia) were associated with a notably higher risk for heart attack after multivariate adjustment in people aged 80-100 (HR, 2.99). Risk was also higher among those aged 70-79 (HR, 1.82).

The highest incidence was in those older than 70. The rate was 8.5 heart attacks per 1,000 people per year among those aged 80-100 and 5.2 heart attacks per 1,000 in those aged 70-79. The rates were 2.5 per 1,000 among those 60-69, 1.8 for those aged 50-59, and 0.8 for those aged 20-49.

“The absolute risk [of cardiovascular events] is of course much higher in the elderly than those under the age of 75, but what was a surprise was how clear our results were on a relative risk scale, that the risk associated with elevated LDL [cholesterol] was as high in people aged 80-100 as the younger patients,” Dr. Nordestgaard said in an interview.

With regard to the benefits of cholesterol-lowering drugs, the study showed that the number needed to prevent one heart attack over 5 years was 80 among those aged 80-100; the number was 439 for people aged 50-59.

With regard to stronger statins, when moderate-intensity statins were used, the number needed to treat to prevent one cardiovascular disease event of any type dropped to 42 for patients aged 80-100. It was 88 for those aged 70-79, 164 for those aged 60-69, 345 for those aged 50-59, and 769 for those aged 20-49.

“The clinical significance of this is that it appears those in older age groups indeed benefit from cholesterol-lowering therapy,” Dr. Nordestgaard said. “I think many people have this idea that LDL [cholesterol] is not important over the age of about 70-75, but that’s not the case.”

“These robust findings are novel,” he and his colleagues stressed.

Despite these observational findings, the South African editorialists noted that “whether lipid-lowering therapy should be initiated for primary prevention in people aged 75 years or older is unclear,” owing to the host of risks and benefits that need to be balanced.

The findings of an ongoing randomized, placebo-controlled trial (STAREE) may answer this question, they wrote. It is investigating primary prevention in 18,000 older patients (≥70 years) who are being randomly assigned to receive atorvastatin 40 mg/d or placebo. The study is seeking to determine whether statin treatment extends the length of a disability-free life, which will be assessed on the basis of survival outside permanent residential care. Results are expected in 2022-2023.
 

Unequivocal reductions in events in elderly, comparable with younger patients

In the second study (Lancet. 2020 Nov 10. doi: 10.1016/S0140-6736[20]32332-1), Baris Gencer, MD, of Brigham and Women’s Hospital, Boston, =and colleagues evaluated the effects of statins and other cholesterol-lowering drugs, including ezetimibe and proprotein convertase subtilisin/kexin type 9 inhibitors, in older versus younger patients.

The systematic review and meta-analysis of 29 randomized controlled trials, also published in the Lancet, were presented virtually as a poster as part of the 2020 American Heart Association scientific session. It included data on 244,090 patients, including 21,492 aged 75 years and older.

The meta-analysis included studies of cardiovascular outcomes of a guideline-recommended LDL cholesterol–lowering drug, with a median follow-up of at least 2 years and inclusion of data on patients aged 75 years and older.

The results showed that over a median follow-up of 2.2 to 6 years, statin use by older patients was associated with a relative risk reduction of major vascular events of 26% per 1 mmol/L reduction in LDL cholesterol (P = .0019), which was comparable with a risk reduction of 15% per 1 mmol/L reduction in LDL cholesterol for patients younger than 75 years (P = .37, compared with older patients).

Treatment of older patients with LDL cholesterol–lowering drugs was also associated with significantly improved outcomes in cardiovascular death (risk ratio, 0.85), MI (RR, 0.80), stroke (RR, 0.73), and coronary revascularization (RR, 0.80).

“We found an unequivocal reduction in the risk of major vascular events with both statin and nonstatin LDL cholesterol-lowering treatments, which was similar to that seen in younger patients,” the authors wrote.

“Cholesterol-lowering medications are affordable drugs that have reduced risk of heart disease for millions of people worldwide, but until now, their benefits for older people have remained less certain,” said lead author Marc Sabatine, MD, also of Brigham and Women’s Hospital, in a Lancet press release.

“Our analysis indicates that these therapies are as effective in reducing cardiovascular events and deaths in people aged 75 years and over as they are in younger people. We found no offsetting safety concerns, and together, these results should strengthen guideline recommendations for the use of cholesterol-lowering medications, including statin and nonstatin therapy, in elderly people.”

The editorialists agreed: “More than 80% of fatal cardiovascular events occur in individuals older than 65 years, and the incidence of cardiovascular events is increasing in those older than 80 years; therefore, the findings of Gencer and colleagues’ study should encourage the use of lipid-lowering therapy in older patients.”

The authors of the two studies have disclosed no relevant financial relationships. Dr. Raal has received research grants, honoraria, or consulting fees for advisory board membership, professional input, and lectures on lipid-lowering drug therapy from Amgen, Regeneron, Sanofi, Novartis, and the Medicines Company.

Raal, PhD, and Farzahna Mohamed, MB BCh, of the University of the Witwatersrand, Johannesburg, South Africa, in an editorial published with both new studies in the Lancet (2020 Nov 10. doi: 10.1016/S0140-6736[20]32333-3).

The studies underscore the need for clinicians to consider continued risks associated with elevated LDL cholesterol in older age, they stressed, adding that statins are also beneficial for younger persons at risk to prevent conditions from worsening.

“The average age of patients in all the trials analyzed was older than 60 years, an age when atherosclerotic cardiovascular disease is already well established,” the editorialists wrote.

“Lipid-lowering therapy should be initiated at a younger age, preferably before age 40 years, in those at risk to delay the onset of atherosclerosis, rather than try to manage the condition once fully established or advanced,” they stressed.
 

No RCTs have included patients older than 70

For persons aged 40-75 years, elevated LDL cholesterol levels are a known risk factor for MI and atherosclerotic cardiovascular disease, and there is consensus in guidelines regarding treatment with statins.

However, the risk for people older than 70 is controversial. Some studies show little or no association between elevated LDL cholesterol levels and an increased risk for MI.

Contributing to the uncertainty is that few of the randomized, controlled trials that have investigated the question have included patients aged older than 70 years.

As a consequence, many practice guidelines have noted that the level of evidence in older patients is low, and some organizations have lowered the strength of recommendations regarding the treatment for older patients in comparison with younger patients.
 

Primary prevention: CV events increase with elevated LDL cholesterol in older age

Dr. Nordestgaard and colleagues studied data on 91,131 people living in Copenhagen who did not have atherosclerotic cardiovascular disease or diabetes at baseline and were not taking statins.

Of the participants, 10,592 were aged 70-79 years, and 3,188 participants were aged 80-100 years.

Over an average follow-up period of 7.7 years, 1,515 participants had a first MI, and 3,389 developed atherosclerotic cardiovascular disease.

In the primary-prevention cohort, after multivariate adjustment, the risk of having a heart attack per 1.0 mmol/L increase in LDL cholesterol was increased in the group overall (hazard ratio, 1.34). The increased risk was observed for all age groups, including those aged 80-100 years (HR, 1.28), 70-79 (HR, 1.25), 60-69 (HR, 1.29), 50-59 (HR, 1.28), and 20-49 (HR, 1.68).

Risk for atherosclerotic cardiovascular disease was also raised per 1.0 mmol/L increase in LDL cholesterol overall (HR, 1.16) and in all age groups, particularly those aged 70-100 years.

Greater elevations in LDL cholesterol (5.0 mmol/L or higher, indicative of possible familial hypercholesterolemia) were associated with a notably higher risk for heart attack after multivariate adjustment in people aged 80-100 (HR, 2.99). Risk was also higher among those aged 70-79 (HR, 1.82).

The highest incidence was in those older than 70. The rate was 8.5 heart attacks per 1,000 people per year among those aged 80-100 and 5.2 heart attacks per 1,000 in those aged 70-79. The rates were 2.5 per 1,000 among those 60-69, 1.8 for those aged 50-59, and 0.8 for those aged 20-49.

“The absolute risk [of cardiovascular events] is of course much higher in the elderly than those under the age of 75, but what was a surprise was how clear our results were on a relative risk scale, that the risk associated with elevated LDL [cholesterol] was as high in people aged 80-100 as the younger patients,” Dr. Nordestgaard said in an interview.

With regard to the benefits of cholesterol-lowering drugs, the study showed that the number needed to prevent one heart attack over 5 years was 80 among those aged 80-100; the number was 439 for people aged 50-59.

With regard to stronger statins, when moderate-intensity statins were used, the number needed to treat to prevent one cardiovascular disease event of any type dropped to 42 for patients aged 80-100. It was 88 for those aged 70-79, 164 for those aged 60-69, 345 for those aged 50-59, and 769 for those aged 20-49.

“The clinical significance of this is that it appears those in older age groups indeed benefit from cholesterol-lowering therapy,” Dr. Nordestgaard said. “I think many people have this idea that LDL [cholesterol] is not important over the age of about 70-75, but that’s not the case.”

“These robust findings are novel,” he and his colleagues stressed.

Despite these observational findings, the South African editorialists noted that “whether lipid-lowering therapy should be initiated for primary prevention in people aged 75 years or older is unclear,” owing to the host of risks and benefits that need to be balanced.

The findings of an ongoing randomized, placebo-controlled trial (STAREE) may answer this question, they wrote. It is investigating primary prevention in 18,000 older patients (≥70 years) who are being randomly assigned to receive atorvastatin 40 mg/d or placebo. The study is seeking to determine whether statin treatment extends the length of a disability-free life, which will be assessed on the basis of survival outside permanent residential care. Results are expected in 2022-2023.
 

Unequivocal reductions in events in elderly, comparable with younger patients

In the second study (Lancet. 2020 Nov 10. doi: 10.1016/S0140-6736[20]32332-1), Baris Gencer, MD, of Brigham and Women’s Hospital, Boston, =and colleagues evaluated the effects of statins and other cholesterol-lowering drugs, including ezetimibe and proprotein convertase subtilisin/kexin type 9 inhibitors, in older versus younger patients.

The systematic review and meta-analysis of 29 randomized controlled trials, also published in the Lancet, were presented virtually as a poster as part of the 2020 American Heart Association scientific session. It included data on 244,090 patients, including 21,492 aged 75 years and older.

The meta-analysis included studies of cardiovascular outcomes of a guideline-recommended LDL cholesterol–lowering drug, with a median follow-up of at least 2 years and inclusion of data on patients aged 75 years and older.

The results showed that over a median follow-up of 2.2 to 6 years, statin use by older patients was associated with a relative risk reduction of major vascular events of 26% per 1 mmol/L reduction in LDL cholesterol (P = .0019), which was comparable with a risk reduction of 15% per 1 mmol/L reduction in LDL cholesterol for patients younger than 75 years (P = .37, compared with older patients).

Treatment of older patients with LDL cholesterol–lowering drugs was also associated with significantly improved outcomes in cardiovascular death (risk ratio, 0.85), MI (RR, 0.80), stroke (RR, 0.73), and coronary revascularization (RR, 0.80).

“We found an unequivocal reduction in the risk of major vascular events with both statin and nonstatin LDL cholesterol-lowering treatments, which was similar to that seen in younger patients,” the authors wrote.

“Cholesterol-lowering medications are affordable drugs that have reduced risk of heart disease for millions of people worldwide, but until now, their benefits for older people have remained less certain,” said lead author Marc Sabatine, MD, also of Brigham and Women’s Hospital, in a Lancet press release.

“Our analysis indicates that these therapies are as effective in reducing cardiovascular events and deaths in people aged 75 years and over as they are in younger people. We found no offsetting safety concerns, and together, these results should strengthen guideline recommendations for the use of cholesterol-lowering medications, including statin and nonstatin therapy, in elderly people.”

The editorialists agreed: “More than 80% of fatal cardiovascular events occur in individuals older than 65 years, and the incidence of cardiovascular events is increasing in those older than 80 years; therefore, the findings of Gencer and colleagues’ study should encourage the use of lipid-lowering therapy in older patients.”

The authors of the two studies have disclosed no relevant financial relationships. Dr. Raal has received research grants, honoraria, or consulting fees for advisory board membership, professional input, and lectures on lipid-lowering drug therapy from Amgen, Regeneron, Sanofi, Novartis, and the Medicines Company.

The more time older women spent sitting or lying down, the more likely their risk of hospitalization for heart failure, based on data from more than 80,000 postmenopausal women.

The 2018 Physical Activity Guidelines show evidence of the impact of physical activity on reducing heart failure risk, but the association between activity, sedentary behavior (SB) and heart failure (HF) in older women in particular has not been well studied, wrote Michael J. LaMonte, PhD, MPH, of the State University of New York at Buffalo, and colleagues in a study published in Circulation: Heart Failure. “Given the high prevalence of prolonged sedentary time among U.S. adults aged 65 and older, among whom HF burden is substantial, understanding the role SB has in HF development is relevant to future HF prevention strategies,” the researchers wrote.

The researchers identified 80,982 women aged 50-79 years who were enrolled in the Women’s Health Initiative Observational Study, had no known HF, and could walk at least one block unassisted. The average follow-up period was 9 years, and a total of 1,402 women were hospitalized for heart failure during the period of time they were observed.

The time spent sedentary (combined sitting or lying down) was divided into tertiles of 6.5 hours or less, 6.6-9.5 hours, and more than 9.5 hours. Time spent sitting was divided into tertiles of 4.5 hours or less; 4.6-8.5 hours; and more than 8.5 hours.
 

Heart failure risk goes up with more down time

After controlling for multiple variables including age, race, education, income, smoking status alcohol use, menopausal hormone therapy, and hysterectomy status, the researchers found that patients in the second tertile for sedentary behavior had a significantly increased heart failure risk than patients in the first tertile for sedentary behavior. This risk was even greater for patients falling in the third tertile for sedentary behavior. Odds ratios were 1.00 (referent), 1.15, and 1.42 for the lowest to highest tertiles for total sedentary behavior, respectively, and 1.00 (referent), 1.14, and 1.54 for sitting (P < .001 for both total sedentary behavior and sitting only).

The trends remained significant after controlling for comorbidities including MI and coronary revascularization, and the associations were similar among categories of women with additional HF risk factors, including body mass index, diabetes, hypertension, and coronary heart disease.

Notably, the association between hours spent sitting or lying down and HF risk persisted even in women who met recommended activity levels, the researchers wrote.

The study findings were limited by the use of self-reports and by the inability to evaluate SB patterns or SB and HF subtypes, the researchers noted. However, the results were strengthened by the large sample size, use of time-varying SB exposure, and extensive controlling, and the data support the risk of increased SB on adverse cardiovascular outcomes.

“Results of this study underscore the need for effective strategies to reduce daily SB time, in addition to increasing recreational physical activity, as part of population efforts for HF prevention,” they concluded.

Clinicians know the value of a physically active lifestyle for heart health, said lead author Dr. LaMonte in a statement accompanying the study’s release. “However, our study clearly shows that we also need to increase efforts to reduce daily sedentary time and encourage adults to frequently interrupt their sedentary time. This does not necessarily require an extended bout of physical activity; it might simply be standing up for 5 minutes or standing and moving one’s feet in place.

“We do not have sufficient evidence on the best approach to recommend for interrupting sedentary time. However, accumulating data suggest that habitual activities such as steps taken during household and other activities of daily living are an important aspect of cardiovascular disease prevention and healthy aging,” Dr. LaMonte added.
 

Promote more movement and less sitting

“This is the first study to assess sedentary time and the risk for incident heart failure hospitalization in postmenopausal women,” said Robert H. Hopkins Jr., MD, of the University of Arkansas for Medical Sciences, Little Rock, in an interview.

“Heart failure is the cause of approximately 35% of cardiovascular mortalities in women, and sedentary behaviors are common in older adults,” he noted.

Kashif J. Piracha, MD, of Houston Methodist Willowbrook Hospital, agreed that there is a lack of existing data looking at the relationship between sedentary behavior and the risk of the development of heart failure in postmenopausal women. In an interview, he cited this as a reason “it was important to conduct this study.”

Dr. Hopkins added that he was not surprised by the study results “There are a number of studies which have demonstrated reduction in risk for heart failure in men and in combined populations of men and women with increased physical activity.” There are fewer data (but similar outcomes) in studies of men with increased levels of sedentary behaviors, he said.

“This study adds one more reason that other clinicians in primary care and me need to encourage our older patients to get up and move,” said Dr. Hopkins, who also serves on the editorial advisory board of Internal Medicine News. “Many of us have focused our efforts in the past on achieving exercise goals and this study provides a foundation for a recommendation that ‘it is not just about exercise;’ we need to also encourage our patients to minimize their time in sedentary pursuits in addition to exercise if we are to optimize their health into older age.”

Dr. Hopkins noted that the large size of the study was a strength, but the observational design and use of patient surveys were limitations.

“We need further studies to better tease out whether there are risk differences in different sedentary behavior patterns, whether this applies across heart failure with reduced ejection fraction versus heart failure with preserved ejection fraction, and whether there are additional ways we can mitigate these risks as our society ages,” he said.
 

Findings differ from California Men’s Health Study’s

“The results corroborate the fact that there is less risk of heart failure in physically active patients,” Dr. Piracha noted.

The message for clinicians is to encourage postmenopausal female patients to engage in physical activity as much as possible, said Dr. Piracha. “Also, it appears that in this population, even with good physical activity, prolonged sedentary behavior of more than 8.5 hours a day was still associated with a higher risk of incident HF hospitalization. Therefore, a case can be made to focus on carrying out physical activity with an intensity that can be sustained for longer, rather than shorter periods of time.”

Notably, the finding of increased HF hospitalization in women who reported high amounts of physical activity but were still sedentary for more than 8.5 hours a day “is contrary to what was seen in the California Men’s Health Study.” In that study, “men with high physical activity levels who also had prolonged sitting time did not have increased risk of HF hospitalization,” Dr. Piracha noted. “Further research is needed to elucidate what hormonal or other factors contribute to this difference.”

The new study was supported by the National Heart, Lung, and Blood Institute. The researchers had no financial conflicts to disclose. Dr. Hopkins and Dr. Piracha had no financial conflicts to disclose.

Study Overview

Objective. To assess whether dapagliflozin added to guideline-recommended therapies is effective and safe over the long-term to reduce the rate of renal and cardiovascular events in patients across multiple chronic kidney disease (CKD) stages, with and without type 2 diabetes.

Design. The Dapagliflozin and Prevention of Adverse Outcomes in CKD (DAPA-CKD) trial (NCT03036150) was a randomized, double-blind, parallel-group, placebo-controlled, multicenter event-driven, clinical trial sponsored by Astra-Zeneca. It was conducted at 386 sites in 21 countries from February 2, 2017, to June 12, 2020. A recruitment period of 24 months and a total study duration of 45 months were initially planned. The primary efficacy analysis was based on the intention-to-treat population. This was the first randomized controlled trial designed to assess the effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on renal and cardiovascular outcomes in patients with CKD.

Setting and participants. This trial randomly assigned 4304 adult participants with CKD stages 2 to 4 (an estimated glomerular filtration rate [GFR] of 25 to 75 mL/min/1.73 m² of body-surface area) and elevated urinary albumin excretion (urinary albumin-to-creatinine ratio of 200 to 5000, measured in mg of albumin per g of creatinine) to receive dapagliflozin (10 mg once daily) or placebo. Exclusion criteria included type 1 diabetes, polycystic kidney disease, lupus nephritis, antineutrophil cytoplasmic antibody–associated vasculitis, recent immunosuppressive therapy for primary or secondary kidney disease, New York Heart Association class IV congestive heart failure, myocardial infarction, unstable angina, stroke or transient ischemic attacks, or recent coronary revascularization or valvular repair/replacement. All participants received a stable dose of renin–angiotensin system inhibitor for 4 weeks prior to screening, and the vast majority received a maximum tolerated dose at enrollment. Randomization was monitored to ensure that at least 30% of participants recruited did not have diabetes and that no more than 10% had stage 2 CKD. Participants were randomly assigned to receive dapagliflozin (n = 2152) or matching placebo (n = 2152) to ensure a 1:1 ratio of the 2 regimens. Dapagliflozin and placebo had identical appearance and administration schedules. All participants and trial personnel (except members of the independent data monitoring committee) were unaware of the trial-group assignments. After randomization, in-person study visits were conducted at 2 weeks, at 2, 4, and 8 months, and at 4-month intervals thereafter.

Main outcome measures. The primary outcome was a composite of the first occurrence of either a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes. Secondary outcomes, in hierarchical order, were: (1) the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes; (2) a composite cardiovascular outcome defined as hospitalization for heart failure or death from cardiovascular causes; and (3) death from any cause. All outcomes were assessed by time-to-event analyses.

Given the extensive prior experience with dapagliflozin, only selected adverse events were recorded. These included serious adverse events, adverse events resulting in the discontinuation of dapagliflozin or placebo, and adverse events of interest to dapagliflozin (eg, volume depletion symptoms, renal events, major hypoglycemia, fractures, diabetic ketoacidosis, events leading to higher risk of lower limb amputation, and lower limb amputations).

Main results. On March 26, 2020, the independent data monitoring committee recommended stopping the trial because of clear efficacy on the basis of 408 primary outcome events. The participants were 61.8 ± 12.1 years of age, and 1425 participants (33.1%) were female. The baseline mean estimated GFR was 43.1 ± 12.4 mL/min/1.73 m², the median urinary albumin-to-creatinine ratio was 949, and 2906 participants (67.5%) had type 2 diabetes. Over a median of 2.4 years, a primary outcome event occurred in 197 participants (9.2%) in the dapagliflozin group and 312 (14.5%) in the placebo group (hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.51-0.72; P < 0.001). The number of participants who needed to be treated during the trial period to prevent 1 primary outcome event was 19 (95% CI, 15-27). The beneficial effect of dapagliflozin compared with placebo was consistent across all 8 prespecified subgroups (ie, age, sex, race, geographic region, type 2 diabetes, estimated GFR, urinary albumin-to-creatinine ratio, and systolic blood pressure) for the primary outcome. The effects of dapagliflozin were similar in participants with type 2 diabetes and in those without type 2 diabetes.

The incidence of each secondary outcome was similarly lower in the dapagliflozin-treated group than in the placebo group. The HR for the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes was 0.56 (95% CI, 0.45-0.68; P < 0.001), and the HR for the composite cardiovascular outcome of hospitalization for heart failure or death from cardiovascular causes was 0.71 (95% CI, 0.55-0.92; P = 0.009). Death occurred in 101 participants (4.7%) in the dapagliflozin group and 146 participants (6.8%) in the placebo group (HR, 0.69; 95% CI, 0.53-0.88; P = 0.004). The known safety profile of dapagliflozin was confirmed by the similar overall incidences of adverse events and serious adverse events in the dapagliflozin and placebo groups.

Conclusion. In patients with CKD, with or without type 2 diabetes, the risk of a composite of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes was significantly lowered by dapagliflozin treatment.

Commentary

Although SGLT2 inhibitors were designed to reduce plasma glucose and hemoglobin A1c (HbA1c) by increasing urinary glucose excretion in a non-insulin-dependent fashion, an increasing number of clinical trials have demonstrated their possible cardiovascular and renal benefits that extend beyond glycemic control. In 2008, the US Food and Drug Administration (FDA) issued a guidance recommending the evaluation of long-term cardiovascular outcomes prior to approval and commercialization of new antidiabetic therapies to ensure minimum cardiovascular risks following the discovery of cardiovascular safety issues associated with antidiabetic compounds, including rosiglitazone, after drug approval. No one foresaw that this recommendation would lead to the discovery of new classes of antidiabetic drugs (glucagon-like peptide 1 [GLP1] and SGLT2 inhibitors) that improve cardiovascular outcomes. A series of clinical trials of SGLT2 inhibitors, including empagliflozin,¹ canagliflozin,² and dapagliflozin,³ showed a reduction in cardiovascular death and hospitalization due to heart failure among patients with type 2 diabetes. Furthermore, a meta-analysis from 2019 found that SGLT2 inhibitors reduced the risk of a composite of cardiovascular death or hospitalization for heart failure by 23% and the risk of progression of kidney failure by 45% in patients with diabetes.⁴ Thus, the strong and consistent evidence from these large and well-designed outcome trials led the American Diabetes Association in its most recent guidelines to recommend adding SGLT2 inhibitors to metformin for the treatment of patients with type 2 diabetes with or at high risk of atherosclerotic cardiovascular disease, heart failure, or CKD, regardless of baseline HbA1c levels or HbA1c target.⁵ As a result of the compelling effects of SGLT2 inhibitors on cardiovascular outcomes in diabetic patients, as well as increasing evidence that these clinical effects were independent of glycemic control, several subsequent trials were conducted to evaluate whether this new class of drugs may improve clinical outcomes in nondiabetic patients.

The Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) was the first clinical trial to investigate the effect of SGLT2 inhibitors on cardiovascular disease in nondiabetic patients. Findings from DAPA-HF showed that dapagliflozin reduced the risk of worsening heart failure or death from cardiovascular causes, independent of the presence of underlying diabetes. This initial finding resonates with a growing body of evidence^6,7 that supports the use of SGLT2 inhibitors as an adjunctive therapy for heart failure in the absence of diabetes.

The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial showed that long-term administration of canagliflozin conferred cardiovascular, as well as renal, protection in patients with type 2 diabetes with CKD.⁸ Similar to the protective effects on heart failure, the renal benefits of SGLT2 inhibitors appeared to be independent of their blood glucose-lowering effects. Thus, these recent discoveries led to the design of the DAPA-CKD trial to further assess the long-term efficacy and safety of the SGLT2 inhibitor dapagliflozin in patients with CKD precipitated by causes other than type 2 diabetes. Although diabetes is the most common cause for CKD, it nonetheless only accounts for 40% of all CKD etiologies. To date, the only classes of medication that have been shown to slow a decline in kidney function in patients with diabetes are angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs). Given that CKD is an important contributor to illness, is associated with diminished quality of life and reduced life expectancy, and increases health care costs, the findings of the DAPA-CKD trial are particularly significant as they show a renal benefit of dapagliflozin treatment across CKD stages that is independent of underlying diabetes. Therefore, SGLT2 inhibitors may offer a new and unique treatment option for millions of patients with CKD worldwide for whom ACE inhibitors and ARBs were otherwise the only treatments to prevent kidney failure. Moreover, with a number-needed-to-treat of 19 to prevent 1 composite renal vascular event over a period of 2.4 years, dapagliflozin requires a much lower number needed to treat compared to ACE inhibitors and ARBs in similar patients.

The trial has several limitations in study design. For example, the management of diabetes and hypertension were left to the discretion of each trial site, in keeping with local clinical practice and guidelines. It is unknown whether this variability in the management of comorbidities that impact kidney function had an effect on the study’s results. In addition, the trial was stopped early as a result of recommendations from an independent committee due to the demonstrated efficacy of dapagliflozin. This may have reduced the statistical power to assess some of the secondary outcomes. Finally, the authors discussed an initial dip in the estimated GFR after initiation of dapagliflozin treatment, similar to that observed in other SGLT2 inhibitor clinical trials. However, they were unable to ascertain the reversibility of this effect after the discontinuation of dapagliflozin because assessment of GFR was not completed after trial closure. Nonetheless, the authors specified that the reversibility of this initial estimated GFR dip had been assessed and observed in other clinical trials involving dapagliflozin.

The nonglycemic benefits of SGLT2 inhibitors, including improvement in renal outcomes, have strong implications for the future management of patients with CKD. If this indication is approved by the FDA and recommended by clinical guidelines, the ease of SGLT2 inhibitor prescription (eg, minimal drug-drug interaction, no titration), treatment administration (orally once daily), and safety profile may lead to wide use of SGLT2 inhibitors by generalists, nephrologists, and endocrinologists in preserving or improving renal outcomes in patients at risk for end-stage kidney disease. Given that SGLT2 inhibitors are a new class of pharmacologic therapeutics, patient education should include a discussion of the possible side effects, such as euglycemic ketoacidosis, genital and urinary tract infection, and foot and leg amputation. Finally, as Strandberg and colleagues reported in a recent commentary,⁹ the safety of SGLT2 inhibitors in older adults with multimorbidity, frailty, and polypharmacy remains unclear. Thus, future studies of SGLT2 inhibitors are needed to better evaluate their clinical effects in older adults.

Applications for Clinical Practice

This trial enrolled a dedicated patient population with CKD and demonstrated a benefit of dapagliflozin in reducing renal and cardiovascular outcomes, regardless of baseline diabetes status. These drugs (dapagliflozin as well as other SGLT2 inhibitors) will likely have a prominent role in future CKD management guidelines. Until then, several barriers remain before SGLT2 inhibitors can be widely used in clinical practice. Among these barriers are FDA approval for their use in patients with and without diabetes with an estimated GFR < 30 mL/min/1.73 m² and lowering the costs of this class of drugs.

Study Overview

Objective. To assess whether dapagliflozin added to guideline-recommended therapies is effective and safe over the long-term to reduce the rate of renal and cardiovascular events in patients across multiple chronic kidney disease (CKD) stages, with and without type 2 diabetes.

Design. The Dapagliflozin and Prevention of Adverse Outcomes in CKD (DAPA-CKD) trial (NCT03036150) was a randomized, double-blind, parallel-group, placebo-controlled, multicenter event-driven, clinical trial sponsored by Astra-Zeneca. It was conducted at 386 sites in 21 countries from February 2, 2017, to June 12, 2020. A recruitment period of 24 months and a total study duration of 45 months were initially planned. The primary efficacy analysis was based on the intention-to-treat population. This was the first randomized controlled trial designed to assess the effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on renal and cardiovascular outcomes in patients with CKD.

Setting and participants. This trial randomly assigned 4304 adult participants with CKD stages 2 to 4 (an estimated glomerular filtration rate [GFR] of 25 to 75 mL/min/1.73 m² of body-surface area) and elevated urinary albumin excretion (urinary albumin-to-creatinine ratio of 200 to 5000, measured in mg of albumin per g of creatinine) to receive dapagliflozin (10 mg once daily) or placebo. Exclusion criteria included type 1 diabetes, polycystic kidney disease, lupus nephritis, antineutrophil cytoplasmic antibody–associated vasculitis, recent immunosuppressive therapy for primary or secondary kidney disease, New York Heart Association class IV congestive heart failure, myocardial infarction, unstable angina, stroke or transient ischemic attacks, or recent coronary revascularization or valvular repair/replacement. All participants received a stable dose of renin–angiotensin system inhibitor for 4 weeks prior to screening, and the vast majority received a maximum tolerated dose at enrollment. Randomization was monitored to ensure that at least 30% of participants recruited did not have diabetes and that no more than 10% had stage 2 CKD. Participants were randomly assigned to receive dapagliflozin (n = 2152) or matching placebo (n = 2152) to ensure a 1:1 ratio of the 2 regimens. Dapagliflozin and placebo had identical appearance and administration schedules. All participants and trial personnel (except members of the independent data monitoring committee) were unaware of the trial-group assignments. After randomization, in-person study visits were conducted at 2 weeks, at 2, 4, and 8 months, and at 4-month intervals thereafter.

Main outcome measures. The primary outcome was a composite of the first occurrence of either a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes. Secondary outcomes, in hierarchical order, were: (1) the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes; (2) a composite cardiovascular outcome defined as hospitalization for heart failure or death from cardiovascular causes; and (3) death from any cause. All outcomes were assessed by time-to-event analyses.

Given the extensive prior experience with dapagliflozin, only selected adverse events were recorded. These included serious adverse events, adverse events resulting in the discontinuation of dapagliflozin or placebo, and adverse events of interest to dapagliflozin (eg, volume depletion symptoms, renal events, major hypoglycemia, fractures, diabetic ketoacidosis, events leading to higher risk of lower limb amputation, and lower limb amputations).

The incidence of each secondary outcome was similarly lower in the dapagliflozin-treated group than in the placebo group. The HR for the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes was 0.56 (95% CI, 0.45-0.68; P < 0.001), and the HR for the composite cardiovascular outcome of hospitalization for heart failure or death from cardiovascular causes was 0.71 (95% CI, 0.55-0.92; P = 0.009).

The known safety profile of dapagliflozin was confirmed by the similar overall incidences of adverse events and serious adverse events in the dapagliflozin and placebo groups.

Conclusion. In patients with CKD, with or without type 2 diabetes, the risk of a composite of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes was significantly lowered by dapagliflozin treatment.

If this indication is approved by the FDA and recommended by clinical guidelines, the ease of SGLT2 inhibitor prescription (eg, minimal drug-drug interaction, no titration), treatment administration (orally once daily), and safety profile may lead to wide use of SGLT2 inhibitors by generalists, nephrologists, and endocrinologists in preserving or improving renal outcomes in patients at risk for end-stage kidney disease. Given that SGLT2 inhibitors are a new class of pharmacologic therapeutics, patient education should include a discussion of the possible side effects, such as euglycemic ketoacidosis, genital and urinary tract infection, and foot and leg amputation. Finally, as Strandberg and colleagues reported in a recent commentary,⁹ the safety of SGLT2 inhibitors in older adults with multimorbidity, frailty, and polypharmacy remains unclear. Thus, future studies of SGLT2 inhibitors are needed to better evaluate their clinical effects in older adults.

Applications for Clinical Practice

This trial enrolled a dedicated patient population with CKD and demonstrated a benefit of dapagliflozin in reducing renal and cardiovascular outcomes, regardless of baseline diabetes status. These drugs (dapagliflozin as well as other SGLT2 inhibitors) will likely have a prominent role in future CKD management guidelines. Until then, several barriers remain before SGLT2 inhibitors can be widely used in clinical practice. Among these barriers are FDA approval for their use in patients with and without diabetes with an estimated GFR < 30 mL/min/1.73 m² and lowering the costs of this class of drugs.

One month of dual-antiplatelet therapy followed by aspirin monotherapy in patients who’ve received a drug-eluting stent proved noninferior to 6-12 months of DAPT for a composite 1-year endpoint of cardiovascular events or major bleeding in the large, randomized One-Month DAPT trial.

Svisio/Thinkstock

This is the first test of such a strategy. Other trials of short-course DAPT, such as the successful TWILIGHT trial, have dropped the aspirin and continued the P2Y12 inhibitor. But aspirin monotherapy after a single month of DAPT is an attractive alternative in patients undergoing PCI for noncomplex lesions, Myeong-Ki Hong, MD, PhD, said in presenting his results at the American Heart Association scientific sessions.

“In everyday clinical practice, people receiving P2Y12 receptor blockers usually complain of several episodes of minor bleeding. And the cost. Those are strong factors in patient noncompliance,” he said, adding, “I think aspirin monotherapy is more comfortable for the physician and the patient.”

The One-Month DAPT trial included 3,020 patients who underwent percutaneous coronary intervention with drug-eluting stents (DES) at 23 Korean centers. They were split roughly 60/40 between patients with stable angina and those with acute coronary syndrome involving unstable angina. Patients with complex coronary lesions or acute MI were not eligible for enrollment. Participants were randomized to receive either the polymer-free drug-coated BioFreedom stent, in which case they got 1 month of DAPT followed by 11 months of aspirin antiplatelet monotherapy, or they received 6 or 12 months of DAPT in conjunction with a thick-strut BioMatrix or an Ultimaster polymer-based DES. The reason for using different stents in the two study arms is that only the polymer-free stent completes drug release within 1 month; other contemporary DESs release their drug for 3-4 months, and it’s risky to discontinue one of the antiplatelet agents during drug elution, said Dr. Hong, professor of cardiology at Yonsei University in Seoul, South Korea.
 

Patients with stable angina fared best

The primary endpoint in this noninferiority trial was the 1-year composite of cardiac death, MI, target vessel revascularization, stroke, or major bleeding. The incidence was 5.9% in the 1-month DAPT group, statistically noninferior to the 6.5% figure in the 6- or 12-month DAPT group. The major bleeding rate at 1 year was 1.7% with 1 month of DAPT and 2.5% with 6-12 months of DAPT, a nonsignificant difference. Of note, the primary composite endpoint occurred in 5.1% of patients with stable angina who were randomized to 1 month of DAPT, compared with 7.6% with 6 or 12 months of DAPT, a statistically significant difference that translated into a 33% relative risk reduction. In contrast, in patients with unstable angina the primary endpoint occurred in 7.2% of those on 1 month of DAPT and 5.1% with 6 or 12 months of DAPT, a trend that didn’t reach significance.

Roughly 75% of patients in the long-DAPT arm were assigned to 12 months of DAPT. That’s because the trial began in 2015, before clinical practice guidelines declared 6 months of DAPT to be the recommendation in patients with stable coronary artery disease. The choice of 6 versus 12 months of DAPT in the trial was left up to the patient’s physician.

Discussant Roisin Colleran, MBBCh, said the study addresses “an unmet clinical need” for improved antiplatelet regimens following PCI with DES.
 

Trial’s shortcomings temper reaction

“After a period of short DAPT, aspirin monotherapy may be preferable to P2Y12 monotherapy because it’s cheaper, with fewer off-target side effects, less variation in treatment response, and fewer contraindications,” said Dr. Colleran, a cardiologist at Mater Private Hospital, Dublin.

That being said, she shared several reservations about the study. For one, none of the three stents used in the trial is approved by the Food and Drug Administration. The results may not be generalizable to non–East Asian populations. The use of 12 months of DAPT in stable angina patients is out of step with current U.S. and European practice guidelines, which recommend 6 months. And 17% of patients in the 1-month DAPT group were noncompliant with that strategy, meaning they continued on DAPT; had that reverse noncompliance rate been lower, the between-group difference in the primary endpoint might have become statistically significant.

Dr. Hong said he thinks the study findings are applicable elsewhere in the world. The 1-month DAPT followed by aspirin monotherapy strategy is attractive in elderly patients, those on oral anticoagulation for atrial fibrillation, individuals who need to undergo noncardiac surgery, and in the large group of stable patients with noncomplex coronary lesions.

“Let’s provide these patients with some options,” the cardiologist urged.

He is particularly keen on the combination of a polymer-free stent with a drug-elution period of less than 1 month.

“Is polymer perfect? I don’t think so. The polymer is a foreign body. It’s fantastic, but in 5 or 10 years the polymer may cause irritation and chronic inflammation and a new lesion,” Dr. Hong said.

Session moderator Wayne B. Batchelor, MD, commented on the battle for stent market share: “It almost appears that we’re getting to a ceiling point with coronary interventions whereby at a year we’re getting such low ischemic event rates – they’re often in the 5%-7% range – that all of these [head-to-head] studies are noninferiority studies, because it’s just the only way to do these comparisons nowadays. We can’t do 10-, 15-, or 20,000-patient trials. But these noninferiority margins are quite broad.”

“Are we stuck just saying: ‘All stents are equal,’ or are we going to be able to get to the point that we can show that a healing stent is superior?” asked Dr. Batchelor, director of interventional cardiology and interventional cardiology research at the Inova Medical Group in Falls Church, Va.

“I think it’s going to be very hard to beat the current technology,” observed panelist Alexandre Abizaid, MD, PhD, of the Dante Pazzanese Institute of Cardiology in São Paulo. “Even though the polymers are durable, they’re biocompatible, and they’re hard to beat. It’s not going to be easy to show superiority. Maybe in patient subsets.”

Dr. Hong reported having no financial conflicts of interest regarding the One-Month DAPT trial, funded by DIO, Cardinal Health Korea, and Terumo.
