Cardiorespiratory fitness linked to cancer risk, mortality?
TOPLINE:
a large Swedish cohort study suggests.
METHODOLOGY:
- A prospective cohort study included 177,709 Swedish men (mean age, 42; mean body mass index, 26 kg/m2) who completed an occupational health profile assessment and were followed for a mean of 9.6 years.
- CRF was assessed by determining maximal oxygen consumption during an aerobic fitness test, known as a submaximal Åstrand cycle ergometer test.
- Participants reported physical activity habits, lifestyle, and perceived health.
- Data on prostate, colon, and lung cancer incidence and mortality were derived from national registers.
- Outcomes from three higher CRF groups (low, > 25-35; moderate, > 35-45; high, > 45 mL/min per kg) were compared with those from the very low CRF group (25 mL/min per kg or less). Models were adjusted for various factors, including age, BMI, education, dietary habits, comorbidity, and smoking.
TAKEAWAY:
- During follow-up, investigators identified 1,918 prostate, 499 colon, and 283 lung cancer cases as well as 141 prostate, 207 lung, and 152 colon cancer deaths.
- In the fully adjusted model, higher CRF levels were associated with a significantly lower risk for colon cancer (hazard ratio, 0.72 for moderate; HR, 0.63 for high).
- In this model, higher CRF was also associated with a lower risk of death from prostate cancer (HR, 0.67 for low; HR, 0.57 for moderate; HR, 0.29 for high).
- For lung cancer mortality, only high CRF was associated with a significantly lower risk of death (HR, 0.41).
- An association between CRF and lung cancer incidence (HR, 0.99) and death (HR, 0.99) was only evident among adults aged 60 and older.
IN PRACTICE:
“The clinical implications of these findings further emphasize the importance of CRF for possibly reducing cancer incidence and mortality,” the authors concluded. “It is important for the general public to understand that higher-intensity [physical activity] has greater effects on CRF and is likely to be more protective against the risk of developing and dying from certain cancers.”
SOURCE:
The study was led by Elin Ekblom-Bak, PhD, from the Swedish School of Sport and Health Sciences, Stockholm. It was published online in JAMA Network Open.
LIMITATIONS:
The study was limited by voluntary participation, inclusion of only employed individuals, and estimations of CRF via submaximal tests. Data on smoking status were not optimal and there was a small number of cancer cases and deaths.
DISCLOSURES:
Funding was provided by the Swedish Cancer Society. The authors have reported no conflicts of interest.

PCPs key to heart failure care after discharge
Madeline Sterling, MD, knew something was wrong when she heard her patient’s voice on the phone. The patient was breathing too fast and sounded fatigued. Like many people with heart failure, this patient had several comorbidities: diabetes, high blood pressure, and cancer, which was in remission.
The patient had been in and out of the hospital several times and was afraid of going back, but Dr. Sterling, a primary care physician, advised her that it was the safe thing to do.
During the woman’s stay, the inpatient cardiology team called Dr. Sterling to provide status updates and ask for input. When the patient was discharged, Dr. Sterling received information on what medicines had been changed and scheduled follow-up care within 10 days. Dr. Sterling, who’d cared for the woman for many years, called her family, her home health aide, and another caregiver to discuss the plan.
“When you know these patients really well, it’s helpful,” Dr. Sterling, a professor of medicine at Weill Cornell Medicine, New York, said. Primary care clinicians have “an appreciation for how all these conditions fit together, how the medicines fit together, and how to put that patient’s priorities at the front of the equation.”
Research has shown that follow-up care within 7-10 days after discharge, especially for patients with heart failure, can prevent hospital readmissions. Patients’ health can change rapidly following discharge: They may start retaining fluid or may not know how to maintain a low-sodium diet, or they might have trouble obtaining medication. Primary care clinicians spot these early warning signs in follow-up visits.
Heart failure affects more than 6 million adults in the United States, according to the Centers for Disease Control and Prevention. The condition is a common cause of hospital readmissions within 30 days of discharge, according to research published by the American Heart Association.
Patients with heart failure are particularly challenging to care for because of comorbidities.
“They’re a very, very sick group of patients that are very difficult to manage,” said Noah Moss, MD, an advanced heart failure and transplant cardiologist at Mount Sinai Hospital, New York.
But patients do not always receive the follow-up care they need, some studies have found.
Right drugs at the right time
Kelly Axsom, MD, a cardiologist at the Columbia University Medical Center, New York, and director of the centralized heart failure management program at the New York–Presbyterian Hospital System, called the primary care clinician the “captain of the ship,” ensuring that medications are reconciled and providing education about what to eat after discharge.
“It’s actually pretty complicated to go from being in the hospital to being at home,” Dr. Axsom said. “There are often many medication changes, there are lots of instructions that are told to you as a patient that are hard to remember.”
A patient’s weight might fluctuate in the days following discharge because the dose of diuretics might be too low or too high and need to be adjusted, according to Ishani Ganguli, MD, MPH, an assistant professor of medicine and a general internist in the Division of General Internal Medicine and Primary Care at Harvard Medical School and Brigham and Women’s Hospital, Boston.
K. Melissa Hayes, DNP, ANP-BC, CHFN, an assistant professor in the adult gerontology primary care program at the Vanderbilt University School of Nursing, Nashville, Tenn., recalled one patient who was given a months’ worth of medications following his discharge from the hospital.
“He was given expensive medications he couldn’t afford and not any refills or how to get those medications,” Dr. Hayes said.
Sometimes patients have no way to get to the pharmacy, or their pharmacy doesn’t have the medication they need, or their insurance doesn’t cover the drugs.
“The average patient is on at least six medications for heart failure, maybe even seven, and then that’s not including all their other medications,” Dr. Hayes said. “That can be a lot for people to keep up with.”
Dr. Hayes talks to her patients with heart failure about what drugs they have been prescribed and what medications they require more of, and she deprescribes any that are duplicative.
Helping patients understand why they are taking each drug encourages them to stick to the regimen. Diuretics, for example, can lead to frequent urination. If patients are unable to take regular bathroom breaks, they may be tempted to stop using the medication – a potentially catastrophic mistake.
“Often I have patients say, ‘Nobody ever explained it to me that way,’ ” Dr. Hayes said. “Someone can have a PhD but not understand their medications.”
Clinicians also can alert patients to commonly used medications that can worsen heart failure, such as diabetes drugs and over-the-counter medications such as ibuprofen.
Patients should be prescribed a combination of four recommended medications. But several studies have found that clinicians often fail to achieve the target doses for those medications. The use of guideline-directed medications reduces mortality and hospitalization rates, according to multiple clinical trials.
Eyes and ears on the patient
Once home, patients must stick to the right diet, weigh themselves every day, and monitor their blood pressure. But changing behaviors can be a struggle.
“Being seen quickly within a couple of days of discharge, you can catch things,” said Dr. Hayes, who has edited a book on managing patients with heart failure in primary care.
“It’s an opportunity to see how they’re doing at home, make sure they have their medications, make sure there’s been no misunderstanding or miscommunication about what they’re supposed to be doing at home,” says Marc Itskowitz, MD, a primary care physician affiliated with Allegheny General Hospital, Pittsburgh.
Ideally, a record that readily integrates information from wearables – such as blood pressure and weight – would make it easier to spot abnormalities, Dr. Itskowtiz said. “I think we’re still in the infancy of the electronic health record,” he said.
Ensuring that follow-up visits are as accessible as possible for patients is also important. Telehealth makes it easier for patients after they return home from the hospital, Dr. Itskowitz said.
More infrastructure
Another challenge of providing follow-up care for patients with heart failure is completing all the tasks a clinician must do within a 20-minute visit: an examination; education on the condition and medications; counseling on diet and exercise; coordination of medical equipment, such as a blood pressure cuff for home use; and making appointments with specialists.
“In the current system, additional support for primary care is needed so we can do all this,” Dr. Sterling said.
Staff at primary care clinics should be trained to answer calls from patients when they experience changes in their weight or are worried about other potential problems. “A lot of primary care practices are bare bones,” Dr. Hayes said, meaning they might not have the staff to field those calls. Educating patients as to when they should call their physician, especially after experiencing worsening symptoms, is also important.
Dr. Hayes suggests setting aside time in the schedule each week to see patients who have been recently discharged from the hospital. In the Cardiology and Vascular Clinic at Nashville General Hospital, Tenn., where she spends half a day each week, Dr. Hayes requests 30 minutes to see patients who have recently been discharged from hospital.
Even when the process goes smoothly, some patients will return to the hospital because of the progressive nature of heart failure, according to Dr. Hayes. Improving care following their hospitalization can keep these people from rapidly declining.
“Most patients with heart failure want to be taking care of the grandchildren or be able to enjoy family dinners together,” Dr. Axsom said. “I think anything we can do to help improve their quality of life is really important.”
Take-home
- See heart failure patients early after their discharge from hospital, ideally within 7-10 days.
- Make sure patients have access to the right medications at the right dosages and that they know why they’re taking them.
- Educate patients about the diet they should be following.
- Have a system to monitor patients’ symptoms and let them know when they should call.

FDA approves first leadless dual-chamber pacing system
already-approved leadless single-chamber device, Abbott has announced.
, one based in part on anThe company’s AVEIR DR leadless pacing system consists of two percutaneously implanted devices, the single-chamber AVEIR VR leadless pacemaker, implanted within the right ventricle, and the novel AVEIR AR single-chamber pacemaker for implantation in the right atrium.
The AVEIR DR system relies on proprietary wireless technology to provide bidirectional, beat-to-beat communication between its two components to achieve dual-chamber synchronization, the company stated in a press release on the approval.
The system also provides real-time pacing analysis, Abbott said, allowing clinicians to assess proper device placement during the procedure and before implantation. The system is designed to be easily removed if the patient’s pacing needs evolve or its battery needs replacing.
Experienced operators achieved a 98% implantation success rate using the AVIER DR system in a 300-patient study conducted at 55 sites in Canada, Europe, and the United States. In that study, 63% of the patients had sinus-node dysfunction and 33% had AV block as their primary dual-chamber pacing indication.
The system exceeded its predefined safety and performance goals, providing AV-synchronous pacing in 97% of patients for at least 3 months, it was reported in May at the annual scientific sessions of the Heart Rhythm Society and in a simultaneous publication in The New England Journal of Medicine.
“Modern medicine has been filled with technological achievements that fundamentally changed how doctors approach patient care, and now we can officially add dual-chamber leadless pacing to that list of achievements,” coauthor Vivek Reddy, MD, director of cardiac arrhythmia services for Mount Sinai Hospital and the Mount Sinai Health System, New York, said in the press release.

already-approved leadless single-chamber device, Abbott has announced.
, one based in part on anThe company’s AVEIR DR leadless pacing system consists of two percutaneously implanted devices, the single-chamber AVEIR VR leadless pacemaker, implanted within the right ventricle, and the novel AVEIR AR single-chamber pacemaker for implantation in the right atrium.
The AVEIR DR system relies on proprietary wireless technology to provide bidirectional, beat-to-beat communication between its two components to achieve dual-chamber synchronization, the company stated in a press release on the approval.
The system also provides real-time pacing analysis, Abbott said, allowing clinicians to assess proper device placement during the procedure and before implantation. The system is designed to be easily removed if the patient’s pacing needs evolve or its battery needs replacing.
Experienced operators achieved a 98% implantation success rate using the AVIER DR system in a 300-patient study conducted at 55 sites in Canada, Europe, and the United States. In that study, 63% of the patients had sinus-node dysfunction and 33% had AV block as their primary dual-chamber pacing indication.

Peripartum cardiomyopathy raises risks at future pregnancy despite LV recovery
, a new study suggests.
Researchers looked at the long-term outcomes in a cohort of women who had developed PPCM and became pregnant again several years later, comparing those with LV function that had “normalized” in the interim against those with persisting LV dysfunction.
In their analysis, adverse maternal outcomes 5 years after an index pregnancy were significantly worse among those in whom LV dysfunction had persisted, compared with those with recovered LV function. The risk of relapsed PPCM persisted out to 8 years. Mortality remained high in both groups through the follow-up.
The study suggests that “women with PPCM need long-term follow-up by cardiology, as mortality does not abate over time,” Kalgi Modi, MD, Louisiana State University, Shreveport, said in an interview.
Women with a history of PPCM, she said, need “multidisciplinary and shared decision-making for family planning, because normalization of left ventricular function after index pregnancy does not guarantee a favorable outcome in the subsequent pregnancies.”
Dr. Modi is senior author on the study published online in the Journal of the American College of Cardiology.
The current findings are important to women with a history of PPCM who are “contemplating future pregnancy,” Afshan Hameed, MD, a maternal-fetal medicine specialist and cardiologist at the University of California, Irvine, said in an interview. The investigators suggest that “complete recovery of cardiac function after PPCM does not guarantee a favorable outcome in future pregnancy,” agreed Dr. Hameed, who was not involved in the current study. Future pregnancies must therefore “be highly discouraged or considered with caution even in patients who have recovered their cardiac function.”
To investigate the impact of PPCM on risk at subsequent pregnancies, the researchers studied 45 patients with PPCM who had gone on to have at least one more pregnancy, the first a median of 28 months later. Their mean age was 27 and 80% were Black; they were followed a median of 8 years.
Peripartum cardiomyopathy, defined as idiopathic heart failure with LV ejection fraction (LVEF) 45% or less in the last month of pregnancy through the following 5 months, was diagnosed post partum in 93.3% and antepartum in the remaining 6.7% (mean time of diagnosis, 6 weeks post partum).
The mean LVEF fell from 45.1% at the index pregnancy to 41.2% (P = .009) at subsequent pregnancies. The “recovery group” included the 30 women with LVEF recovery to 50% or higher after the index pregnancy, and the remaining 15 with persisting LV dysfunction – defined as LVEF < 50% – made up the “nonrecovery group.”
Recovery of LVEF was associated with a reduced risk of persisting LV dysfunction, the report states, at a hazard ratio of 0.08 (95% CI, 0.01-0.64; P = .02) after adjustment for hypertension, diabetes, and history of preeclampsia. But that risk went up sharply in association with illicit drug use, similarly adjusted, with an HR of 9.08 (95% CI, 1.38-59.8; P = .02).
The nonrecovery group, compared with the recovery group, experienced significantly higher rates of adverse maternal outcomes (53.3% vs. 20.0%; P = .04) – a composite endpoint that included relapse PPCM (33.3% vs. 3.3%; P = .01), HF (53.3% vs. 20.0%; P = .03), cardiogenic shock, thromboembolic events, and death – at 5 years. However, all-cause mortality was nonsignificantly different between the two groups (13.3% vs. 3.3%; P = .25)
All-cause mortality was nonsignificantly different between the two groups at a median of 8 years (20.0% vs. 20.0%; P = 1.00), and the difference in overall adverse maternal outcomes had gone from significant to nonsignificant (53.3% vs. 33.3%; P = .20). The difference in relapse PPCM between groups remained significant after 8 years (53.3% vs. 23.3%; P = .04)
The study is limited by its retrospective nature, a relatively small population, and lack of racial diversity, the report notes.
Indeed, most of the study’s subjects were Black, and previous studies have demonstrated a “different phenotypic presentation and outcome in African American women with PPCM, compared with non–African American women,” an accompanying editorial states.
Therefore, applicability of its findings to other populations “needs to be examined by urgently needed national prospective registries with long-term follow-up,” writes Uri Elkayam, MD, University of Southern California, Los Angeles.
Moreover, the study questions “whether the reverse remodeling and improvement of [LVEF] in women with PPCM represent a true recovery.” Prior studies “have shown an impaired contractile reserve as well as abnormal myocardial strain and reduced exercise capacity and even mortality in women with PPCM after RLV,” Dr. Elkayam notes.
It’s therefore possible – as with other forms of dilated cardiomyopathy – that LVEF normalization “does not represent a true recovery but a new steady state with subclinical myocardial dysfunction that is prone to development of recurrent [LV dysfunction] and clinical deterioration in response to various triggers such as long-standing hypertension, obesity, diabetes, illicit drug use,” and, “more importantly,” subsequent pregnancies.
The study points to “the need for a close long-term follow-up of women with PPCM” and provides “a rationale for early initiation of guideline-directed medical therapy after the diagnosis of PPCM and possible continuation even after improvement of LVEF.”
No funding source was reported. Dr. Modi and coauthors, Dr. Elkayam, and Dr. Hameed declare no relevant financial relationships.

FROM THE JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY
New ESH hypertension guidelines aim for simplified message
The guidelines, which are endorsed by the European Renal Association and the International Society of Hypertension, were presented during the annual European Meeting on Hypertension and Cardiovascular Protection Meeting in Milan, Italy.
The guidelines consensus document was also published online in the Journal of Hypertension. Giuseppe Mancia, MD, professor emeritus of medicine, University Milano-Bicocca, Italy, and Reinhold Kreutz, MD, PhD, Charité–University Medicine Berlin, were cochairs of the task force that created the document.
“We have tried to provide a simplified message to key topics with these new guidelines,” Dr. Kreutz said in an interview.
“We have confirmed the definition of hypertension and provide clear guidance for blood pressure monitoring and a simplified general strategy targeting similar blood pressure goals for most patients, although the treatment algorithms of how you get there may be different for different patient groups.”
Dr. Kreutz added: “Because hypertension is so prevalent and many patients have comorbidities, it is not easy to have one approach for all, but we have tried to simplify the key messages as much as possible, with a target that is more general to the whole population.”
While there are no major surprises in the guidelines, there are multiple advances and added-value changes, including clear advice on how to measure blood pressure, an upgrade for beta-blockers in the treatment algorithms, and a new definition and treatment recommendations for “true resistant hypertension.”
Definition remains unchanged
The definition of hypertension remains unchanged from the previous guidelines – repeated office systolic blood pressure values of ≥ 140 mm Hg and/or diastolic blood pressure values of ≥ 90 mm Hg.
“The definition and classification of hypertension has not changed in these new guidelines,” Dr. Kreutz said. “While there have been suggestions that the definition/target should be changed again, particularly about blood pressure lowering being beneficial at the very low pressure range, after reviewing all the evidence we do not agree with this, and we are standing with the definition of hypertension when intervention is beneficial rather than doing nothing or causing harm.”
Clear guidance on measurement
Dr. Kreutz points out that the correct measurement of blood pressure is of key importance, and the new guidelines include a detailed algorithm on how to measure blood pressure. The preferred method is automated cuff-based blood pressure measurement.
“There are still many variations in blood pressure measurement in clinical practice, so we now have clear guidance on how to measure blood pressure in the office but also at home,” he commented.
They have upgraded the use of out-of-office blood pressure measurement, particularly home measurement, as useful in long-term management. “In future, there should be more emphasis on follow-up using technology with remote control and virtual care.”
Thresholds for starting treatment
On thresholds for initiating antihypertensive therapy, the guidelines recommend that treatment be initiated for most patients when systolic blood pressure is ≥ 140 mm Hg or diastolic blood pressure is ≥ 90 mm Hg.
The same recommendation is given for patients with grade 1 hypertension (systolic, 140-159 mm Hg; and/or diastolic, 90-99 mm Hg) irrespective of cardiovascular risk, although they add that for patients in the lower blood pressure range who have no hypertension-mediated organ damage and who are at low cardiovascular risk, consideration may be given to starting treatment with lifestyle changes only. If, however, blood pressure control is not achieved within a few months of a lifestyle-based approach alone, drug treatment is necessary.
For older patients (aged 80 or older), the task force recommends initiation of drug treatment at 160 mm Hg systolic, although a lower systolic threshold of 140-160 mm Hg may be considered. The authors note that thresholds for the initiation of drug treatment for very frail patients should be individualized.
Blood pressure targets
In the new guidelines, the blood pressure target is the same as in the previous guidelines for the general population of patients with hypertension. The goal is < 140/80 mm Hg for most patients. This accounts for the major portion of the protective effect of blood pressure lowering.
However, the consensus document notes that despite the smaller incremental benefit, an effort should be made to reach a range of 120-129/70-79 mm Hg, but only if treatment is well tolerated to avoid the risk of treatment discontinuation because of adverse events, which might offset, in part or completely, the incremental reduction in cardiovascular outcomes.
Elaborating on this, Dr. Kreutz said, “We should aim for the systolic blood pressure to be within the range of below 140 mm Hg down to 120 mm Hg, with a specific target of around 130 mm Hg for most patients and lower in patients in whom drug treatments are well tolerated and who are at high risk.
“The problem is, if we go for a target of lower that 130 mm Hg, the evidence gets weaker, the benefits diminish, and we risk losing patients because of adverse effects from using so many drugs,” he added. “But in younger and fitter patients, we would recommend the lower the better, but not below 120 mm Hg.”
Dr. Kreutz noted that the new guidelines have tried to simplify recommendations on target pressures. “We have tried to simplify guidance to focus on a target of around 130 for almost all patients. Before, it wasn’t so clear. There were different targets for different groups of patients with various comorbidities or older patients. But now we are saying the range of 120 to 139 is suitable for the vast majority of patients.”
The guidelines do allow slightly higher targets for older and very frail patients.
Drug treatments
The guidelines advise that blood pressure lowering be prioritized over the selection of specific antihypertensive drug classes. The use of any of the five major drug classes – angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, calcium blockers, and thiazide/thiazidelike diuretics – and their combinations are recommended as the basis of antihypertensive treatment strategies.
They advise starting with a two-drug combination for most patients. The preferred combinations including a renin-angiotensin blocker (either an ACE inhibitor or an ARB) with a calcium blocker or a thiazide/thiazidelike diuretic, preferably in a single-pill combination to reduce pill burden and improve adherence and outcome.
If blood pressure is not controlled with the initial two-drug combination at the maximum recommended and tolerated dose of the respective components, treatment should be increased to a three-drug combination.
“We can control 60% of patients in the general hypertensive population with dual therapy, and up to 90% with triple therapy,” Dr. Kreutz said. “Only a small percentage need a fourth drug.”
A new feature of the guidelines is the upgrading of beta-blockers in the treatment algorithms.
“Beta-blockers may not have previously been considered as a first choice of antihypertensive medication, but we see that in clinical practice, many patients are actually treated with these drugs because there are so many conditions in which beta-blockers have a compelling evidence-based indication or are believed to be favorable,” he said. “So, we are now positioning beta-blockers as drugs that can be used at any step of the treatment algorithm if there is a guideline directed indication or other conditions for which they are thought to be beneficial.”
The guidelines also recommend that all drugs be given as once-daily preparations and that they be taken preferably in the morning.
“The new TIME study has established that there is no difference in outcome with morning or evening dosing, but we know that adherence is often better when drugs are taken in the morning, and it is not advisable to take diuretics in the evening,” Dr. Kreutz said.
‘True resistant hypertension’
The guidelines have introduced a new term, “true resistant hypertension,” defined as systolic blood pressure of ≥ 140 mm Hg or diastolic blood pressure of ≥ 90 mm Hg in the presence of the following conditions: the maximum recommended and tolerated doses of a three-drug combination comprising a renin-angiotensin system blocker (either an ACE inhibitor or an ARB), a calcium blocker, and a thiazide/thiazidelike diuretic were used; inadequate blood pressure control has been confirmed by ambulatory (preferable) or home blood pressure measurement; and various causes of pseudo-resistant hypertension (especially poor medication adherence) and secondary hypertension have been excluded.
“There are many patients who may appear to have resistant hypertension, but we need to screen them carefully to ensure they are adherent to treatment, and then most of these patients are found not to be truly resistant,” Dr. Kreutz explained. “We estimate that only about 5% of patients have true resistant hypertension.”
For these patients with true resistant hypertension, two treatment approaches are recommended.
For those who do not have advanced kidney disease (glomerular filtration rate > 40 mL/min), renal denervation can be considered. This is a new II B recommendation.
Dr. Kreutz noted that studies of renal denervation excluded patients with advanced kidney disease, so there are no data for this group. For these patients, the guidelines suggest that a combination diuretic approach (chlorthalidone with a loop diuretic) could be considered in light of the results of the recent CLICK study.
Differences from U.S. guidelines?
Commenting on the new European guidelines for this news organization, Paul Whelton, MD, chair of the most recent American College of Cardiology/American Heart Association hypertension guidelines committee, said: “Publication of these guidelines is important. I congratulate the European task force. It is an enormous amount of time and effort.”
Dr. Whelton, who is Show Chwan Chair in Global Public Health at Tulane University, New Orleans, and president of the World Hypertension League, added: “I would say the changes are incremental rather than major, but that is probably appropriate.”
He welcomed the greater emphasis on out-of-office blood pressure measurement, saying, “That’s where we should be headed.”
Asked how the European guidelines differ from the U.S. guidelines, Dr. Whelton commented: “There are differences, but they are not huge. The major hypertension guidelines across the world are much more alike than they are different.”
He pointed out that both the U.S. and European guidelines aim for a target blood pressure of 130/80 mm Hg for most patients but have different ways of issuing that advice.
“The Europeans recommend a minimum goal of 140/90 mm Hg, and if there are no issues, then press on to get to under 130/80 mm Hg. That’s kind of a two-step process,” he said. “In the U.S., we’ve gone for a more direct approach of just recommending less than 130/80 mm Hg.
“My fear with the European approach is that by saying, get to 140/90 mm Hg first, then move on to 130/80 mm Hg, is that you’re likely to lose people. And doctors could feel that 140/90 is fine.”
More effort needed on implementation
Dr. Whelton says that where all hypertension guidelines are lacking is in the implementation of the recommendations.
“We are all falling down on implementation,” he said. “We have a huge burden of illness, and it is a very cost-effective area for management, but still, rates of blood pressure control are very bad. Generally speaking, even with a very conservative target of 140/90, the best countries only have control rates of around 30%, and this can be as low as 8% in some low/middle-income countries.”
Dr. Whelton believes the approach to blood pressure management needs to change.
“We know that the current traditional model of care, where blood pressure is managed by your local doctor, is not working. It is hopeless,” he said. “That is not an indictment of these doctors. It’s just that they have more pressing issues to deal with, so we need to look at other models.”
He suggests that the way forward is through convenient, community-based care delivered by a team in which nonphysicians assist in much of the management and in which reliable, affordable medications are given at the point of care, with patients tracked with electronic health records so as to identify those who are not adhering to their medication regimens.
“We know that using simple protocols will work for the vast majority of people. We don’t need to individualize or complicate this too much. That tends to lose people in the process.”
Dr. Whelton makes the point that it is well known how to diagnose and treat hypertension, yet this is not being done well.
“We are doing these things really badly. In routine care, blood pressure is measured horribly. Nobody would accept a pilot of a plane saying he should be doing all these procedures but he’s too busy and it’s probably okay, but that’s the way blood pressure is often measured in clinical practice,” he added. “And we can’t really do a good job if were not measuring the key variable properly that the diagnosis is based on.”
Dr. Whelton also points out that the medical profession is not making enough effort to have patients reach target levels.
“If you’re in a country where very few people are being treated and very high pressures are common, then of course you have to focus on that group first. But in most of the Western world, we are long past that, so we can move on down the chain. We then get to a lot more people with moderately high blood pressure getting exposed to increases in risk, and while this is not quite as dramatic as those with very high pressures at the individual risk level, because there are so many of them, that’s where a lot of events are occurring,” he says.
“If we get everyone to 140/90 mm Hg, we can probably prevent 60% of blood pressure–related events. But if we can get them all down to 130 mm Hg systolic, then we can prevent 75%-80% of events. It’s often quite easy to get to that target, but patients need help and encouragement.”
Going forward, he concluded, guidelines should pivot to focus more on implementation.
“We all try to make the guidelines as approachable as possible, but they are encyclopedic, and many doctors just continue doing what they are doing. That is our big challenge.”

The definition of hypertension remains unchanged from the previous guidelines – repeated office systolic blood pressure values of ≥ 140 mm Hg and/or diastolic blood pressure values of ≥ 90 mm Hg.
“The definition and classification of hypertension has not changed in these new guidelines,” Dr. Kreutz said. “While there have been suggestions that the definition/target should be changed again, particularly about blood pressure lowering being beneficial at the very low pressure range, after reviewing all the evidence we do not agree with this, and we are standing with the definition of hypertension when intervention is beneficial rather than doing nothing or causing harm.”
Clear guidance on measurement
Dr. Kreutz points out that the correct measurement of blood pressure is of key importance, and the new guidelines include a detailed algorithm on how to measure blood pressure. The preferred method is automated cuff-based blood pressure measurement.
“There are still many variations in blood pressure measurement in clinical practice, so we now have clear guidance on how to measure blood pressure in the office but also at home,” he commented.
They have upgraded the use of out-of-office blood pressure measurement, particularly home measurement, as useful in long-term management. “In future, there should be more emphasis on follow-up using technology with remote control and virtual care.”
Thresholds for starting treatment
On thresholds for initiating antihypertensive therapy, the guidelines recommend that treatment be initiated for most patients when systolic blood pressure is ≥ 140 mm Hg or diastolic blood pressure is ≥ 90 mm Hg.
The same recommendation is given for patients with grade 1 hypertension (systolic, 140-159 mm Hg; and/or diastolic, 90-99 mm Hg) irrespective of cardiovascular risk, although they add that for patients in the lower blood pressure range who have no hypertension-mediated organ damage and who are at low cardiovascular risk, consideration may be given to starting treatment with lifestyle changes only. If, however, blood pressure control is not achieved within a few months of a lifestyle-based approach alone, drug treatment is necessary.
For older patients (aged 80 or older), the task force recommends initiation of drug treatment at 160 mm Hg systolic, although a lower systolic threshold of 140-160 mm Hg may be considered. The authors note that thresholds for the initiation of drug treatment for very frail patients should be individualized.
Blood pressure targets
In the new guidelines, the blood pressure target is the same as in the previous guidelines for the general population of patients with hypertension. The goal is < 140/80 mm Hg for most patients. This accounts for the major portion of the protective effect of blood pressure lowering.
However, the consensus document notes that despite the smaller incremental benefit, an effort should be made to reach a range of 120-129/70-79 mm Hg, but only if treatment is well tolerated to avoid the risk of treatment discontinuation because of adverse events, which might offset, in part or completely, the incremental reduction in cardiovascular outcomes.
Elaborating on this, Dr. Kreutz said, “We should aim for the systolic blood pressure to be within the range of below 140 mm Hg down to 120 mm Hg, with a specific target of around 130 mm Hg for most patients and lower in patients in whom drug treatments are well tolerated and who are at high risk.
“The problem is, if we go for a target of lower that 130 mm Hg, the evidence gets weaker, the benefits diminish, and we risk losing patients because of adverse effects from using so many drugs,” he added. “But in younger and fitter patients, we would recommend the lower the better, but not below 120 mm Hg.”
Dr. Kreutz noted that the new guidelines have tried to simplify recommendations on target pressures. “We have tried to simplify guidance to focus on a target of around 130 for almost all patients. Before, it wasn’t so clear. There were different targets for different groups of patients with various comorbidities or older patients. But now we are saying the range of 120 to 139 is suitable for the vast majority of patients.”
The guidelines do allow slightly higher targets for older and very frail patients.
Drug treatments
The guidelines advise that blood pressure lowering be prioritized over the selection of specific antihypertensive drug classes. The use of any of the five major drug classes – angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, calcium blockers, and thiazide/thiazidelike diuretics – and their combinations are recommended as the basis of antihypertensive treatment strategies.
They advise starting with a two-drug combination for most patients. The preferred combinations including a renin-angiotensin blocker (either an ACE inhibitor or an ARB) with a calcium blocker or a thiazide/thiazidelike diuretic, preferably in a single-pill combination to reduce pill burden and improve adherence and outcome.
If blood pressure is not controlled with the initial two-drug combination at the maximum recommended and tolerated dose of the respective components, treatment should be increased to a three-drug combination.
“We can control 60% of patients in the general hypertensive population with dual therapy, and up to 90% with triple therapy,” Dr. Kreutz said. “Only a small percentage need a fourth drug.”
A new feature of the guidelines is the upgrading of beta-blockers in the treatment algorithms.
“Beta-blockers may not have previously been considered as a first choice of antihypertensive medication, but we see that in clinical practice, many patients are actually treated with these drugs because there are so many conditions in which beta-blockers have a compelling evidence-based indication or are believed to be favorable,” he said. “So, we are now positioning beta-blockers as drugs that can be used at any step of the treatment algorithm if there is a guideline directed indication or other conditions for which they are thought to be beneficial.”
The guidelines also recommend that all drugs be given as once-daily preparations and that they be taken preferably in the morning.
“The new TIME study has established that there is no difference in outcome with morning or evening dosing, but we know that adherence is often better when drugs are taken in the morning, and it is not advisable to take diuretics in the evening,” Dr. Kreutz said.
‘True resistant hypertension’
The guidelines have introduced a new term, “true resistant hypertension,” defined as systolic blood pressure of ≥ 140 mm Hg or diastolic blood pressure of ≥ 90 mm Hg in the presence of the following conditions: the maximum recommended and tolerated doses of a three-drug combination comprising a renin-angiotensin system blocker (either an ACE inhibitor or an ARB), a calcium blocker, and a thiazide/thiazidelike diuretic were used; inadequate blood pressure control has been confirmed by ambulatory (preferable) or home blood pressure measurement; and various causes of pseudo-resistant hypertension (especially poor medication adherence) and secondary hypertension have been excluded.
“There are many patients who may appear to have resistant hypertension, but we need to screen them carefully to ensure they are adherent to treatment, and then most of these patients are found not to be truly resistant,” Dr. Kreutz explained. “We estimate that only about 5% of patients have true resistant hypertension.”
For these patients with true resistant hypertension, two treatment approaches are recommended.
For those who do not have advanced kidney disease (glomerular filtration rate > 40 mL/min), renal denervation can be considered. This is a new II B recommendation.
Dr. Kreutz noted that studies of renal denervation excluded patients with advanced kidney disease, so there are no data for this group. For these patients, the guidelines suggest that a combination diuretic approach (chlorthalidone with a loop diuretic) could be considered in light of the results of the recent CLICK study.
Differences from U.S. guidelines?
Commenting on the new European guidelines for this news organization, Paul Whelton, MD, chair of the most recent American College of Cardiology/American Heart Association hypertension guidelines committee, said: “Publication of these guidelines is important. I congratulate the European task force. It is an enormous amount of time and effort.”
Dr. Whelton, who is Show Chwan Chair in Global Public Health at Tulane University, New Orleans, and president of the World Hypertension League, added: “I would say the changes are incremental rather than major, but that is probably appropriate.”
He welcomed the greater emphasis on out-of-office blood pressure measurement, saying, “That’s where we should be headed.”
Asked how the European guidelines differ from the U.S. guidelines, Dr. Whelton commented: “There are differences, but they are not huge. The major hypertension guidelines across the world are much more alike than they are different.”
He pointed out that both the U.S. and European guidelines aim for a target blood pressure of 130/80 mm Hg for most patients but have different ways of issuing that advice.
“The Europeans recommend a minimum goal of 140/90 mm Hg, and if there are no issues, then press on to get to under 130/80 mm Hg. That’s kind of a two-step process,” he said. “In the U.S., we’ve gone for a more direct approach of just recommending less than 130/80 mm Hg.
“My fear with the European approach is that by saying, get to 140/90 mm Hg first, then move on to 130/80 mm Hg, is that you’re likely to lose people. And doctors could feel that 140/90 is fine.”
More effort needed on implementation
Dr. Whelton says that where all hypertension guidelines are lacking is in the implementation of the recommendations.
“We are all falling down on implementation,” he said. “We have a huge burden of illness, and it is a very cost-effective area for management, but still, rates of blood pressure control are very bad. Generally speaking, even with a very conservative target of 140/90, the best countries only have control rates of around 30%, and this can be as low as 8% in some low/middle-income countries.”
Dr. Whelton believes the approach to blood pressure management needs to change.
“We know that the current traditional model of care, where blood pressure is managed by your local doctor, is not working. It is hopeless,” he said. “That is not an indictment of these doctors. It’s just that they have more pressing issues to deal with, so we need to look at other models.”
He suggests that the way forward is through convenient, community-based care delivered by a team in which nonphysicians assist in much of the management and in which reliable, affordable medications are given at the point of care, with patients tracked with electronic health records so as to identify those who are not adhering to their medication regimens.
“We know that using simple protocols will work for the vast majority of people. We don’t need to individualize or complicate this too much. That tends to lose people in the process.”
Dr. Whelton makes the point that it is well known how to diagnose and treat hypertension, yet this is not being done well.
“We are doing these things really badly. In routine care, blood pressure is measured horribly. Nobody would accept a pilot of a plane saying he should be doing all these procedures but he’s too busy and it’s probably okay, but that’s the way blood pressure is often measured in clinical practice,” he added. “And we can’t really do a good job if were not measuring the key variable properly that the diagnosis is based on.”
Dr. Whelton also points out that the medical profession is not making enough effort to have patients reach target levels.
“If you’re in a country where very few people are being treated and very high pressures are common, then of course you have to focus on that group first. But in most of the Western world, we are long past that, so we can move on down the chain. We then get to a lot more people with moderately high blood pressure getting exposed to increases in risk, and while this is not quite as dramatic as those with very high pressures at the individual risk level, because there are so many of them, that’s where a lot of events are occurring,” he says.
“If we get everyone to 140/90 mm Hg, we can probably prevent 60% of blood pressure–related events. But if we can get them all down to 130 mm Hg systolic, then we can prevent 75%-80% of events. It’s often quite easy to get to that target, but patients need help and encouragement.”
Going forward, he concluded, guidelines should pivot to focus more on implementation.
“We all try to make the guidelines as approachable as possible, but they are encyclopedic, and many doctors just continue doing what they are doing. That is our big challenge.”

The guidelines, which are endorsed by the European Renal Association and the International Society of Hypertension, were presented during the annual European Meeting on Hypertension and Cardiovascular Protection Meeting in Milan, Italy.
The guidelines consensus document was also published online in the Journal of Hypertension. Giuseppe Mancia, MD, professor emeritus of medicine, University Milano-Bicocca, Italy, and Reinhold Kreutz, MD, PhD, Charité–University Medicine Berlin, were cochairs of the task force that created the document.
“We have tried to provide a simplified message to key topics with these new guidelines,” Dr. Kreutz said in an interview.
“We have confirmed the definition of hypertension and provide clear guidance for blood pressure monitoring and a simplified general strategy targeting similar blood pressure goals for most patients, although the treatment algorithms of how you get there may be different for different patient groups.”
Dr. Kreutz added: “Because hypertension is so prevalent and many patients have comorbidities, it is not easy to have one approach for all, but we have tried to simplify the key messages as much as possible, with a target that is more general to the whole population.”
While there are no major surprises in the guidelines, there are multiple advances and added-value changes, including clear advice on how to measure blood pressure, an upgrade for beta-blockers in the treatment algorithms, and a new definition and treatment recommendations for “true resistant hypertension.”

New definition for iron deficiency in CV disease proposed
with implications that may extend to cardiovascular disease in general.
In the study involving more than 900 patients with PH, investigators at seven U.S. centers determined the prevalence of iron deficiency by two separate definitions and assessed its associations with functional measures and quality of life (QoL) scores.
An iron deficiency definition used conventionally in heart failure (HF) – ferritin less than 100 g/mL or 100-299 ng/mL with transferrin saturation (TSAT) less than 20% – failed to discriminate patients with reduced peak oxygen consumption (peakVO2), 6-minute walk test (6MWT) results, and QoL scores on the 36-item Short Form Survey (SF-36).
But an alternative definition for iron deficiency, simply a TSAT less than 21%, did predict such patients with reduced peakVO2, 6MWT, and QoL. It was also associated with an increased mortality risk. The study was published in the European Heart Journal.
“A low TSAT, less than 21%, is key in the pathophysiology of iron deficiency in pulmonary hypertension” and is associated with those important clinical and functional characteristics, lead author Pieter Martens MD, PhD, said in an interview. The study “underscores the importance of these criteria in future intervention studies in the field of pulmonary hypertension testing iron therapies.”
A broader implication is that “we should revise how we define iron deficiency in heart failure and cardiovascular disease in general and how we select patients for iron therapies,” said Dr. Martens, of the Heart, Vascular & Thoracic Institute of the Cleveland Clinic.
Iron’s role in pulmonary vascular disease
“Iron deficiency is associated with an energetic deficit, especially in high energy–demanding tissue, leading to early skeletal muscle acidification and diminished left and right ventricular (RV) contractile reserve during exercise,” the published report states. It can lead to “maladaptive RV remodeling,” which is a “hallmark feature” predictive of morbidity and mortality in patients with pulmonary vascular disease (PVD).
Some studies have suggested that iron deficiency is a common comorbidity in patients with PVD, their estimates of its prevalence ranging widely due in part to the “absence of a uniform definition,” write the authors.
Dr. Martens said the current study was conducted partly in response to the increasingly common observation that the HF-associated definition of iron deficiency “has limitations.” Yet, “without validation in the field of pulmonary hypertension, the 2022 pulmonary hypertension guidelines endorse this definition.”
As iron deficiency is a causal risk factor for HF progression, Dr. Martens added, the HF field has “taught us the importance of using validated definitions for iron deficiency when selecting patients for iron treatment in randomized controlled trials.”
Moreover, some evidence suggests that iron deficiency by some definitions may be associated with diminished exercise capacity and QoL in patients with PVD, which are associations that have not been confirmed in large studies, the report notes.
Therefore, it continues, the study sought to “determine and validate” the optimal definition of iron deficiency in patients with PVD; document its prevalence; and explore associations between iron deficiency and exercise capacity, QoL, and cardiac and pulmonary vascular remodeling.
Evaluating definitions of iron deficiency
The prospective study, called PVDOMICS, entered 1,195 subjects with available iron levels. After exclusion of 38 patients with sarcoidosis, myeloproliferative disease, or hemoglobinopathy, there remained 693 patients with “overt” PH, 225 with a milder form of PH who served as PVD comparators, and 90 age-, sex-, race/ethnicity- matched “healthy” adults who served as controls.
According to the conventional HF definition of iron deficiency – that is, ferritin 100-299 ng/mL and TSAT less than 20% – the prevalences were 74% in patients with overt PH and 72% of those “across the PVD spectrum.”
But by that definition, iron deficient and non-iron deficient patients didn’t differ significantly in peakVO2, 6MWT distance, or SF-36 physical component scores.
In contrast, patients meeting the alternative definition of iron deficiency of TSAT less than 21% showed significantly reduced functional and QoL measures, compared with those with TSAT greater than or equal to 21%.
The group with TSAT less than 21% also showed significantly more RV remodeling at cardiac MRI, compared with those who had TSAT greater than or equal to 21%, but their invasively measured pulmonary vascular resistance was comparable.
Of note, those with TSAT less than 21% also showed significantly increased all-cause mortality (hazard ratio, 1.63; 95% confidence interval, 1.13-2.34; P = .009) after adjustment for age, sex, hemoglobin, and natriuretic peptide levels.
“Proper validation of the definition of iron deficiency is important for prognostication,” the published report states, “but also for providing a working definition that can be used to identify suitable patients for inclusion in randomized controlled trials” of drugs for iron deficiency.
Additionally, the finding that TSAT less than 21% points to patients with diminished functional and exercise capacity is “consistent with more recent studies in the field of heart failure” that suggest “functional abnormalities and adverse cardiac remodeling are worse in patients with a low TSAT.” Indeed, the report states, such treatment effects have been “the most convincing” in HF trials.
Broader implications
An accompanying editorial agrees that the study’s implications apply well beyond PH. It highlights that iron deficiency is common in PH, while such PH is “not substantially different from the problem in patients with heart failure, chronic kidney disease, and cardiovascular disease in general,” lead editorialist John G.F. Cleland, MD, PhD, University of Glasgow, said in an interview. “It’s also common as people get older, even in those without these diseases.”
Dr. Cleland said the anemia definition currently used in cardiovascular research and practice is based on a hemoglobin concentration below the 5th percentile of age and sex in primarily young, healthy people, and not on its association with clinical outcomes.
“We recently analyzed data on a large population in the United Kingdom with a broad range of cardiovascular diseases and found that unless anemia is severe, [other] markers of iron deficiency are usually not measured,” he said. A low hemoglobin and TSAT, but not low ferritin levels, are associated with worse prognosis.
Dr. Cleland agreed that the HF-oriented definition is “poor,” with profound implications for the conduct of clinical trials. “If the definition of iron deficiency lacks specificity, then clinical trials will include many patients without iron deficiency who are unlikely to benefit from and might be harmed by IV iron.” Inclusion of such patients may also “dilute” any benefit that might emerge and render the outcome inaccurate.
But if the definition of iron deficiency lacks sensitivity, “then in clinical practice, many patients with iron deficiency may be denied a simple and effective treatment.”
Measuring serum iron could potentially be useful, but it’s usually not done in randomized trials “especially since taking an iron tablet can give a temporary ‘blip’ in serum iron,” Dr. Cleland said. “So TSAT is a reasonable compromise.” He said he “looks forward” to any further data on serum iron as a way of assessing iron deficiency and anemia.
Half full vs. half empty
Dr. Cleland likened the question of whom to treat with iron supplementation as a “glass half full versus half empty” clinical dilemma. “One approach is to give iron to everyone unless there’s evidence that they’re overloaded,” he said, “while the other is to withhold iron from everyone unless there’s evidence that they’re iron depleted.”
Recent evidence from the IRONMAN trial suggested that its patients with HF who received intravenous iron were less likely to be hospitalized for infections, particularly COVID-19, than a usual-care group. The treatment may also help reduce frailty.
“So should we be offering IV iron specifically to people considered iron deficient, or should we be ensuring that everyone over age 70 get iron supplements?” Dr. Cleland mused rhetorically. On a cautionary note, he added, perhaps iron supplementation will be harmful if it’s not necessary.
Dr. Cleland proposed “focusing for the moment on people who are iron deficient but investigating the possibility that we are being overly restrictive and should be giving iron to a much broader population.” That course, however, would require large population-based studies.
“We need more experience,” Dr. Cleland said, “to make sure that the benefits outweigh any risks before we can just give iron to everyone.”
Dr. Martens has received consultancy fees from AstraZeneca, Abbott, Bayer, Boehringer Ingelheim, Daiichi Sankyo, Novartis, Novo Nordisk, and Vifor Pharma. Dr. Cleland declares grant support, support for travel, and personal honoraria from Pharmacosmos and Vifor. Disclosures for other authors are in the published report and editorial.

An iron deficiency definition used conventionally in heart failure (HF) – ferritin less than 100 g/mL or 100-299 ng/mL with transferrin saturation (TSAT) less than 20% – failed to discriminate patients with reduced peak oxygen consumption (peakVO2), 6-minute walk test (6MWT) results, and QoL scores on the 36-item Short Form Survey (SF-36).
But an alternative definition for iron deficiency, simply a TSAT less than 21%, did predict such patients with reduced peakVO2, 6MWT, and QoL. It was also associated with an increased mortality risk. The study was published in the European Heart Journal.
“A low TSAT, less than 21%, is key in the pathophysiology of iron deficiency in pulmonary hypertension” and is associated with those important clinical and functional characteristics, lead author Pieter Martens MD, PhD, said in an interview. The study “underscores the importance of these criteria in future intervention studies in the field of pulmonary hypertension testing iron therapies.”
A broader implication is that “we should revise how we define iron deficiency in heart failure and cardiovascular disease in general and how we select patients for iron therapies,” said Dr. Martens, of the Heart, Vascular & Thoracic Institute of the Cleveland Clinic.
Iron’s role in pulmonary vascular disease
“Iron deficiency is associated with an energetic deficit, especially in high energy–demanding tissue, leading to early skeletal muscle acidification and diminished left and right ventricular (RV) contractile reserve during exercise,” the published report states. It can lead to “maladaptive RV remodeling,” which is a “hallmark feature” predictive of morbidity and mortality in patients with pulmonary vascular disease (PVD).
Some studies have suggested that iron deficiency is a common comorbidity in patients with PVD, their estimates of its prevalence ranging widely due in part to the “absence of a uniform definition,” write the authors.
Dr. Martens said the current study was conducted partly in response to the increasingly common observation that the HF-associated definition of iron deficiency “has limitations.” Yet, “without validation in the field of pulmonary hypertension, the 2022 pulmonary hypertension guidelines endorse this definition.”
As iron deficiency is a causal risk factor for HF progression, Dr. Martens added, the HF field has “taught us the importance of using validated definitions for iron deficiency when selecting patients for iron treatment in randomized controlled trials.”
Moreover, some evidence suggests that iron deficiency by some definitions may be associated with diminished exercise capacity and QoL in patients with PVD, which are associations that have not been confirmed in large studies, the report notes.
Therefore, it continues, the study sought to “determine and validate” the optimal definition of iron deficiency in patients with PVD; document its prevalence; and explore associations between iron deficiency and exercise capacity, QoL, and cardiac and pulmonary vascular remodeling.
Evaluating definitions of iron deficiency
The prospective study, called PVDOMICS, entered 1,195 subjects with available iron levels. After exclusion of 38 patients with sarcoidosis, myeloproliferative disease, or hemoglobinopathy, there remained 693 patients with “overt” PH, 225 with a milder form of PH who served as PVD comparators, and 90 age-, sex-, race/ethnicity- matched “healthy” adults who served as controls.
According to the conventional HF definition of iron deficiency – that is, ferritin 100-299 ng/mL and TSAT less than 20% – the prevalences were 74% in patients with overt PH and 72% of those “across the PVD spectrum.”
But by that definition, iron deficient and non-iron deficient patients didn’t differ significantly in peakVO2, 6MWT distance, or SF-36 physical component scores.
In contrast, patients meeting the alternative definition of iron deficiency of TSAT less than 21% showed significantly reduced functional and QoL measures, compared with those with TSAT greater than or equal to 21%.
The group with TSAT less than 21% also showed significantly more RV remodeling at cardiac MRI, compared with those who had TSAT greater than or equal to 21%, but their invasively measured pulmonary vascular resistance was comparable.
Of note, those with TSAT less than 21% also showed significantly increased all-cause mortality (hazard ratio, 1.63; 95% confidence interval, 1.13-2.34; P = .009) after adjustment for age, sex, hemoglobin, and natriuretic peptide levels.
“Proper validation of the definition of iron deficiency is important for prognostication,” the published report states, “but also for providing a working definition that can be used to identify suitable patients for inclusion in randomized controlled trials” of drugs for iron deficiency.
Additionally, the finding that TSAT less than 21% points to patients with diminished functional and exercise capacity is “consistent with more recent studies in the field of heart failure” that suggest “functional abnormalities and adverse cardiac remodeling are worse in patients with a low TSAT.” Indeed, the report states, such treatment effects have been “the most convincing” in HF trials.
Broader implications
An accompanying editorial agrees that the study’s implications apply well beyond PH. It highlights that iron deficiency is common in PH, while such PH is “not substantially different from the problem in patients with heart failure, chronic kidney disease, and cardiovascular disease in general,” lead editorialist John G.F. Cleland, MD, PhD, University of Glasgow, said in an interview. “It’s also common as people get older, even in those without these diseases.”
Dr. Cleland said the anemia definition currently used in cardiovascular research and practice is based on a hemoglobin concentration below the 5th percentile of age and sex in primarily young, healthy people, and not on its association with clinical outcomes.
“We recently analyzed data on a large population in the United Kingdom with a broad range of cardiovascular diseases and found that unless anemia is severe, [other] markers of iron deficiency are usually not measured,” he said. A low hemoglobin and TSAT, but not low ferritin levels, are associated with worse prognosis.
Dr. Cleland agreed that the HF-oriented definition is “poor,” with profound implications for the conduct of clinical trials. “If the definition of iron deficiency lacks specificity, then clinical trials will include many patients without iron deficiency who are unlikely to benefit from and might be harmed by IV iron.” Inclusion of such patients may also “dilute” any benefit that might emerge and render the outcome inaccurate.
But if the definition of iron deficiency lacks sensitivity, “then in clinical practice, many patients with iron deficiency may be denied a simple and effective treatment.”
Measuring serum iron could potentially be useful, but it’s usually not done in randomized trials “especially since taking an iron tablet can give a temporary ‘blip’ in serum iron,” Dr. Cleland said. “So TSAT is a reasonable compromise.” He said he “looks forward” to any further data on serum iron as a way of assessing iron deficiency and anemia.
Half full vs. half empty
Dr. Cleland likened the question of whom to treat with iron supplementation as a “glass half full versus half empty” clinical dilemma. “One approach is to give iron to everyone unless there’s evidence that they’re overloaded,” he said, “while the other is to withhold iron from everyone unless there’s evidence that they’re iron depleted.”
Recent evidence from the IRONMAN trial suggested that its patients with HF who received intravenous iron were less likely to be hospitalized for infections, particularly COVID-19, than a usual-care group. The treatment may also help reduce frailty.
“So should we be offering IV iron specifically to people considered iron deficient, or should we be ensuring that everyone over age 70 get iron supplements?” Dr. Cleland mused rhetorically. On a cautionary note, he added, perhaps iron supplementation will be harmful if it’s not necessary.
Dr. Cleland proposed “focusing for the moment on people who are iron deficient but investigating the possibility that we are being overly restrictive and should be giving iron to a much broader population.” That course, however, would require large population-based studies.
“We need more experience,” Dr. Cleland said, “to make sure that the benefits outweigh any risks before we can just give iron to everyone.”
Dr. Martens has received consultancy fees from AstraZeneca, Abbott, Bayer, Boehringer Ingelheim, Daiichi Sankyo, Novartis, Novo Nordisk, and Vifor Pharma. Dr. Cleland declares grant support, support for travel, and personal honoraria from Pharmacosmos and Vifor. Disclosures for other authors are in the published report and editorial.

Pulmonary embolism confers higher mortality long term
Topline
Long-term mortality rates among individuals who have had a pulmonary embolism are significantly higher than rates in the general population.
Methodology
Researchers investigated long-term outcomes of patients with pulmonary embolism in a single-center registry.
They followed 896 patients for up to 14 years.
Data were from consecutive cases treated between May 2005 and December 2017.
Takeaway
The total follow-up time was 3,908 patient-years (median, 3.1 years).
One-year and five-year mortality rates were 19.7% (95% confidence interval, 17.2%-22.4%) and 37.1% (95% CI, 33.6%-40.5%), respectively, for patients with pulmonary embolism.
The most frequent causes of death were cancer (28.5%), pulmonary embolism (19.4%), infections (13.9%), and cardiovascular events (11.6%).
Late mortality (>30 days) was more frequent than in the general population for patients with cancer (5-year standardized mortality ratio, 2.77; 95% CI, 2.41-3.16) and for patients without cancer (1.80; 95% CI, 1.50-2.14), compared with expected rates.

CV benefit from vitamin D caps hinted in huge D-Health trial
in an analysis from a large prospective randomized trial.
Risk reductions on vitamin D in the mixed primary- and secondary-prevention population were slight in absolute terms but reached a significant 19% in the case of myocardial infarction (MI).
Over 5 years, 6.6% of those in placebo group experienced major CV events, the primary endpoint, compared with 6% in the vitamin D group. The difference, which corresponded to 5.8 fewer events per 1,000 participants, was short of significance in adjusted analysis.
Still, vitamin-D supplementation was associated with the potential MI benefit and an 11% drop in risk for coronary revascularization.
Also, a subgroup analysis hinted at a potentially reduced CV-event risk from vitamin-D supplementation among individuals who entered the trial on statins or other CV medications generally.
“Most other studies have not found benefit for vitamin D for major CV events,” senior investigator Rachel E. Neale, PhD, said in an interview. Although there was a significant effect for MI, the difference in the composite primary endpoint fell short of significance “in keeping with the other studies.”
“However, the effects for myocardial infarction in people taking statins or cardiovascular disease drugs at baseline are suggestive of benefit,” said Dr. Neale, of QIMR Berghofer Medical Research Institute, Queensland, Australia. Still, “it is important to keep in mind that these may be chance findings.”
The analysis based on the D-Health study was published online in The BMJ.
Benefits minimal
The 21,302 patients in the D-Health trial, conducted in Australia from 2014 to 2020, were randomly assigned double-blind to receive either placebo or vitamin D3 supplements for a planned 5 years. They were instructed to take one placebo or vitamin D capsule per month, each active capsule containing 60,000 IU of the vitamin.
People with self-reported hypercalcemia, hyperparathyroidism, kidney stones, osteomalacia, or sarcoidosis, and those taking greater than 500 IU/day vitamin D supplements were excluded from enrollment. Participants ranged in age from 60 to 84 at randomization and 46% were women.
With 80% of the 10,658 participants assigned to vitamin D and 78% of the 10,644 control subjects completing the 5-year intervention, 6% and 6.6%, respectively, met the primary endpoint of a major CV event, defined as MI, stroke, or coronary revascularization.
The hazard ratio for a vitamin-D effect on the primary endpoint was 0.91 (95% confidence interval, 0.81-1.01). The number needed to treat to avoid one major CV event was 172.
The HR for MI was 0.81 (95% CI, 0.67-0.98), for coronary intervention was 0.89 (0.78-1.01), and for stroke was 0.99 (0.80-1.23).
Adverse event rates were similar at about 16% in both groups and included hypercalcemia, kidney stones, gastrointestinal issues, and skin rash.
Vitamin D at moderate dosages has low toxicity, Dr. Neale said, “so I think it would be reasonable for clinicians to consider supplementing elderly people who do not have contraindications, particularly those who have underlying risk factors for CV disease,” Dr. Neale said. But patients should be told that the evidence for such a recommendation is not strong, so they can make an informed decision, she added.
Also, in general “we would be cautious about extrapolating to formulations other than those used in the study,” Dr. Neale said. “However, in this case, I think it would be reasonable to extrapolate to the use of 2,000 IU per day taken orally, provided that the same adherence can be maintained for a lengthy period.”
Chance findings?
Based on the current study and in light of prior research, “it is premature to recommend vitamin D supplementation for cardiovascular disease prevention specifically,” Nour Makarem, PhD, of the Mailman School of Public Health, Columbia University, New York, said in an interview.
“Prior clinical trials did not show an association between vitamin D supplementation and cardiovascular events,” observed Dr. Makarem, who is not affiliated with the current study. Also, she agreed, it looked at “multiple outcomes, which increases the likelihood that findings may be due to chance.”
She added that the study’s authors observed a possible vitamin-D protective effect “among people who were vitamin D sufficient at baseline but not among those who were insufficient. It is important to interpret this finding with caution because they used predicted, not measured, vitamin D status for these analyses.”
There’s a need for studies in other populations, including younger persons and “particularly populations with higher rates of vitamin D deficiency,” Dr. Makarem observed. Also, further research should aim to “understand the interactions between vitamin D supplementation and cardiovascular medications, including statins.”
The D-Health Trial is funded by National Health and Medical Research Council project grants. Dr. Neale was supported by fellowships from the NHMRC. Neither she nor Dr. Makarem reported any relevant financial relationships.

People with self-reported hypercalcemia, hyperparathyroidism, kidney stones, osteomalacia, or sarcoidosis, and those taking greater than 500 IU/day vitamin D supplements were excluded from enrollment. Participants ranged in age from 60 to 84 at randomization and 46% were women.
With 80% of the 10,658 participants assigned to vitamin D and 78% of the 10,644 control subjects completing the 5-year intervention, 6% and 6.6%, respectively, met the primary endpoint of a major CV event, defined as MI, stroke, or coronary revascularization.
The hazard ratio for a vitamin-D effect on the primary endpoint was 0.91 (95% confidence interval, 0.81-1.01). The number needed to treat to avoid one major CV event was 172.
The HR for MI was 0.81 (95% CI, 0.67-0.98), for coronary intervention was 0.89 (0.78-1.01), and for stroke was 0.99 (0.80-1.23).
Adverse event rates were similar at about 16% in both groups and included hypercalcemia, kidney stones, gastrointestinal issues, and skin rash.
Vitamin D at moderate dosages has low toxicity, Dr. Neale said, “so I think it would be reasonable for clinicians to consider supplementing elderly people who do not have contraindications, particularly those who have underlying risk factors for CV disease,” Dr. Neale said. But patients should be told that the evidence for such a recommendation is not strong, so they can make an informed decision, she added.
Also, in general “we would be cautious about extrapolating to formulations other than those used in the study,” Dr. Neale said. “However, in this case, I think it would be reasonable to extrapolate to the use of 2,000 IU per day taken orally, provided that the same adherence can be maintained for a lengthy period.”
Chance findings?
Based on the current study and in light of prior research, “it is premature to recommend vitamin D supplementation for cardiovascular disease prevention specifically,” Nour Makarem, PhD, of the Mailman School of Public Health, Columbia University, New York, said in an interview.
“Prior clinical trials did not show an association between vitamin D supplementation and cardiovascular events,” observed Dr. Makarem, who is not affiliated with the current study. Also, she agreed, it looked at “multiple outcomes, which increases the likelihood that findings may be due to chance.”
She added that the study’s authors observed a possible vitamin-D protective effect “among people who were vitamin D sufficient at baseline but not among those who were insufficient. It is important to interpret this finding with caution because they used predicted, not measured, vitamin D status for these analyses.”
There’s a need for studies in other populations, including younger persons and “particularly populations with higher rates of vitamin D deficiency,” Dr. Makarem observed. Also, further research should aim to “understand the interactions between vitamin D supplementation and cardiovascular medications, including statins.”
The D-Health Trial is funded by National Health and Medical Research Council project grants. Dr. Neale was supported by fellowships from the NHMRC. Neither she nor Dr. Makarem reported any relevant financial relationships.

The invisible effect medical notes could have on care
In the mid-1990s, when Somnath Saha was a medical resident at the University of California, San Francisco, School of Medicine, he came across a cluster of studies showing that Black people with cardiovascular disease were treated less aggressively, compared with White people. The findings were “appalling” to the young physician who describes himself as a “Brown kid from suburban St. Louis, Missouri.”
Dr. Saha had experienced racism growing up, but was surprised to see such clear signs of inequity within the field of medicine. “There was an injustice happening in my own backyard,” he said.
Indeed, bias towards Black patients can be challenging because many doctors either don’t realize their biases or won’t admit to them. Dr. Saha, now a professor of medicine at Johns Hopkins University, likens implicit bias – unconscious judgments that can affect behavior – to “an invisible force.”
While numerous studies have found evidence of racial discrimination in medicine through patient reports, less is known about how implicit bias shows up in medical records, and how stigmatizing language in patient notes can affect the care that Black patients receive.
That’s part of the reason why, about 7 years ago, Dr. Saha began poring through medical records. For him, they offered a window into doctors’ feelings about their patients.
As part of his latest research, Dr. Saha’s team examined the records of nearly 19,000 patients, paying particular attention to negative descriptions that may influence a clinician’s decision-making. The data, which were recently presented at the 2023 American Association for the Advancement of Science annual meeting, aren’t yet published, but it suggests what researchers have long speculated: The notes provide, at times, a surprisingly candid view of how patients are perceived by doctors, and how their race may affect treatment.
The study adds to a concerning body of literature that explores how racial bias manifests in health care. Researchers like Dr. Saha are interested in how such prejudice leaves a paper trail, which can then reinforce negative stereotypes. Because medical notes get passed between physicians, Dr. Saha’s research suggests they can affect the health of Black patients down the line.
“The medical record is like a rap sheet, it stays with you,” Dr. Saha said, adding that “these things that we say about patients get eternalized.”
Research has long shown that Black patients experience worse health outcomes, compared with White patients, in part because of biased medical care. Black women, for example, are three times more likely to die from pregnancy-related complications, compared with White women. And Black patients often report feeling like physicians don’t listen to their needs or don’t believe their concerns.
Studies appear to back that up. Last year, researchers at the University of Washington found that non-Hispanic White children who went to the emergency room for migraines were more likely to receive pain medications, compared with children of color – even though the two groups reported similar pain scores. Other studies echo similar results for adults as well.
While Michael Sun, a resident physician at the University of Chicago, knew about such health disparities, by his own admission, he was naive about the biases in medical records. At that time, Dr. Sun had “no experience in the medical record, in documentation, or in physician language and culture,” he said.
But in Dr. Sun’s first year of medical school, his professor shared the story of a longtime patient, whom she had referred to an outside specialist. In his recollection, the professor regarded her patient in kind terms, having worked with her for some time to treat a chronic illness. But when she got the specialist’s notes back, she was confused by the description of her patient: Terms like “really difficult,” “noncompliant,” and “uninterested in their health.” This was not the patient she remembered.
“This, as a first-year medical student, really shocked me because I had taken at face value that any words used in notes were true, were valid, or rightfully used,” said Dr. Sun. “I realized all the ways that bias, untold stories, and unknown context may change the way that we view our patients.”
Like Dr. Saha, Dr. Sun became interested in how bias influenced the relationship between doctor and patient, and how these interactions were memorialized in the medical record. In a study published last year, he and his colleagues looked at more than 40,000 medical notes from 18,459 patients. Researchers first manually combed through the notes, then used this information to teach a machine learning algorithm to interpret the connotations of words. Compared with White patients, Black patients were about 2.5 times more likely to be described negatively, with terms like “challenging,” “angry,” and “noncompliant.”
Dr. Saha has used similar methodology – and found similar results – in his own research. For the study presented at the AAAS meeting, his team first read through more than 100,000 medical notes to identify language their team considered to be disparaging – which they chose based on a list of words and phrases from prior research. They then used machine learning to find those terms in medical notes, taking care to ensure context was considered. For example, if the word “aggressive” was used to describe a treatment plan, it was excluded from their analysis. But if “aggressive” was used to describe the patient, it was included.
Dr. Saha pointed to three categories of stigmatizing language that were the most pronounced: expressing doubt or disbelief in what the patient said, such as reporting they “claimed” to experience pain; insinuating that the patient was confrontational, using words like “belligerent” or combative;” and suggesting a patient was not cooperating with a doctor’s orders by saying they “refused” medical advice.
“We’ve known for some time that in health care we sometimes use language that can be confusing or even insulting,” Matthew Wynia, director of the Center for Bioethics and Humanities at the University of Colorado at Denver, Aurora, wrote in an email to Undark. But he noted that research such as Dr. Saha’s has drawn attention to a previously overlooked issue. Describing a patient as “noncompliant” with medications, he said, “makes it sound like the patient is intentionally refusing to follow advice when, in fact, there are many reasons why people might not be able to follow our advice and intentional refusal isn’t even a very common one.”
Dr. Saha noted that, if a patient isn’t taking their medication, it’s important that doctors note that, so that the next physician doesn’t overprescribe them. But the concern, he said, is whether doctors are using these terms appropriately and for the right reasons because of the implications they have for patients.
If a doctor portrays their patient negatively, Dr. Saha said, it can “trigger the next clinician to read them and formulate a potentially negative opinion about that patient” before they’ve even had a chance to interact.
Still, stigmatizing language is only one small piece of the puzzle. What also matters, Dr. Saha said, is how those words can have an impact on care. In prior work, Dr. Saha has shown how implicit and, in some cases, explicit bias, affects a patient’s treatment recommendations.
In a 2018 study, Dr. Saha, along with his wife, Mary Catherine Beach – also a professor at Johns Hopkins University – combed through reports of patients with sickle cell anemia. Their team focused on that particular population since sickle cell patients are some of the most stigmatized in the health care system: Most patients are Black and many require regular doses of opioids for pain management.
In the notes, they found numerous examples of details that were irrelevant to patients’ health concerns: phrases like “girlfriend requests bus token,” “cursing at nurse,” “girlfriend on bed with shoes on,” and “narcotic dependent.”
Dr. Saha and Dr. Beach wanted to see how these remarks might influence a physician’s treatment recommendations, so they used vignettes they had found in the medical records of sickle cell patients. They showed either a vignette which had described patients negatively, or one that was edited with neutral language. Then they asked medical students and residents about the dose of pain medication they would hypothetically recommend. Dr. Beach said that the purpose was to see how what she called “dog whistles about social class or race or something that would make the person seem less educated” would impact treatment recommendations.
The study found that medical notes with stigmatizing language were associated with “less aggressive management of the patient’s pain.” Doctors who read the stigmatizing language chart notes prescribed less pain medication to patients even in cases when they commented that their pain was a 10 out of 10.
“The fact that we were able to show that this bias transmits to the next doctor has been the thing that I think motivates doctors to take it seriously,” said Dr. Beach.
Pain management has become a focal point for researchers because many of the most glaring racial tropes about patient care have revolved around pain. In 2016, a study conducted at the University of Virginia found that half of the 418 medical students and residents surveyed endorsed false beliefs about Black patients. For example, that “Blacks’ nerve endings are less sensitive than whites” and “Blacks’ skin is thicker than whites.” What’s more, those who endorsed these false beliefs also rated Black patients’ pain as lower than White patients’.
Antoinette M. Schoenthaler, a professor of population health and medicine at New York University and associate director of research at the school’s Institute for Excellence in Health Equity, said that disparities in pain management are pervasive and widespread across the medical profession. They seep into treatments for sickle cell anemia, but also prenatal care. As a result, she said, Black patients across the board are often fearful of attending appointments.
“Patients of color go into an appointment with feelings of heightened anxiety because they’re expecting mistreatment,” said Dr. Schoenthaler. “We’ve seen minoritized patients have higher blood pressure in the context of a clinical visit because of these expectations of anxiety and fear, and disappointment.”
Disparities in health care between Black and White patients is a complex issue – one which can’t be solved by addressing medical records alone. But, for researchers like Dr. Saha, Dr. Beach, and Dr. Sun, they can offer a road map that outlines where differences in care begin. The words a clinician uses sets the path for how a patient may be treated in the future.
One way to combat implicit bias, Dr. Saha suggested, is to use an algorithm that identifies stigmatizing language to “give hospital departments or clinicians report cards on how much of this language that they’re using.” By benchmarking averages against one another, clinicians could know if they’re using stigmatizing language at an above average rate. This is something he is considering for future research.
When clinicians are made aware of their biases – when the unconscious becomes conscious – Dr. Saha told Undark that he’s optimistic they’ll work to change them: “We’re using language that we’ve used forever without realizing the potential impact that it has on patient care.”

When clinicians are made aware of their biases – when the unconscious becomes conscious – Dr. Saha told Undark that he’s optimistic they’ll work to change them: “We’re using language that we’ve used forever without realizing the potential impact that it has on patient care.”

New AHA statement on ischemia after cardiac surgery
The American Heart Association outlines “considerations” on the management of acute postoperative myocardial ischemia (PMI) after cardiac surgery in a scientific statement.
Although an infrequent event, acute PMI following cardiac surgery can rapidly evolve and become a potentially life-threatening complication, the writing group, led by Mario Gaudino, MD, PhD, with Weill Cornell Medicine, New York, points out.
The new statement was published online in Circulation.
Data show that the incidence of postoperative myocardial infarction after cardiac surgery ranges from 0.3% to 9.8% after isolated coronary artery bypass graft (CABG) surgery and 0.7% to 11.8% after concomitant valvular surgery. For isolated mitral valve surgery, incidence ranges from 1.7% to 2.2%.
Short-term mortality is elevated among patients with acute PMI, irrespective of the type of surgery. Reported mortality rates range from 5.1% to 24%; the evidence on long-term mortality has been mixed.
Graft-related factors are the most common cause of PMI after CABG, but other factors may contribute, including technical factors, competitive flow, suture entrapment, or coronary artery distortion, as well as non–graft related factors.
Prompt diagnosis and treatment important
Currently, there is no consensus definition of PMI. Elevations in cardiac biomarkers may not be reliable for diagnosis after surgery, and pain management regimens may mask symptoms of ischemia, the writing group notes.
Delay in urgent angiography has been associated with higher mortality; thus, a low threshold for action is encouraged for patients with suspected acute PMI.
Indications for urgent angiography include new ECG changes, chest pain with ongoing signs of ischemia, cardiac imaging abnormalities, cardiac rhythm abnormalities, significant elevations in cardiac biomarkers, and low cardiac output syndrome despite postoperative pressor support.
Patients with acute PMI and low cardiac output syndrome may require mechanical support when first-line treatment fails.
The writing group says fast and effective reperfusion of the ischemic zone, which is generally achieved by percutaneous intervention and, less often, by repeat surgery, is the key to a good clinical outcome.
The statement was prepared by the volunteer writing group on behalf of the AHA Council on Cardiovascular Surgery and Anesthesia; Council on Clinical Cardiology; Council on Cardiovascular and Stroke Nursing; and Stroke Council.
The research had no commercial funding. Disclosures for the writing group are listed with the original article.
