Fresh look at ISCHEMIA bolsters conservative message in stable CAD

The more complicated a primary endpoint, the greater a puzzle it can be for clinicians to interpret the results. It’s likely even tougher for patients, who don’t help choose the events studied in clinical trials yet are increasingly sharing in the management decisions they influence.

That creates an opening for a more patient-centered take on one of cardiology’s most influential recent studies, ISCHEMIA, which bolsters the case for conservative, med-oriented management over a more invasive initial strategy for patients with stable coronary artery disease (CAD) and positive stress tests, researchers said.

The new, prespecified analysis replaced the trial’s conventional primary endpoint of major adverse cardiac events (MACE) with one based on “days alive out of hospital” (DAOH) and found an early advantage for the conservative approach, with caveats.

Those assigned to the conservative arm benefited with more out-of-hospital days throughout the next 2 years than those in the invasive-management group, owing to the latter’s protocol-mandated early cath-lab work-up with possible revascularization. The difference averaged more than 6 days for much of that time.

But DAOH evened out for the two groups by the fourth year in the analysis of more than 5,000 patients.

Protocol-determined cath procedures accounted for 61% of hospitalizations in the invasively managed group. A secondary DAOH analysis that excluded such required hospital days, also prespecified, showed no meaningful difference between the two strategies over the 4 years, noted the report published online May 3 in JAMA Cardiology.
 

DOAH is ‘very, very important’

The DAOH metric has been a far less common consideration in clinical trials, compared with clinical events, yet in some ways it is as “hard” a metric as mortality, encompasses a broader range of outcomes, and may matter more to patients, it’s been argued.

“The thing patients most value is time at home. So they don’t want to be in the hospital, they don’t want to be away from friends, they want to do recreation, or they may want to work,” lead author Harvey D. White, DSc, Green Lane Cardiovascular Services, Auckland (New Zealand) City Hospital, University of Auckland, told this news organization.

“When we need to talk to patients – and we do need to talk to patients – to have a days-out-of-hospital metric is very, very important,” he said. It is not only patient focused, it’s “meaningful in terms of the seriousness of events,” in that length of hospitalization tracks with clinical severity, observed Dr. White, who is slated to present the analysis May 17 during the virtual American College of Cardiology 2021 scientific sessions.

As previously reported, ISCHEMIA showed no significant effect on the primary endpoint of cardiovascular mortality, MI, or hospitalization for unstable anginaheart failure, or resuscitated cardiac arrest by assignment group over a median 3.2 years. Angina and quality of life measures were improved for patients in the invasive arm.

With an invasive initial strategy, “What we know now is that you get nothing of an advantage in terms of the composite endpoint, and you’re going to spend 6 days more in the hospital in the first 2 years, for largely no benefit,” Dr. White said.

That outlook may apply out to 4 years, the analysis suggests, but could conceivably change if DAOH is reassessed later as the ISCHEMIA follow-up continues for what is now a planned total of 10 years.

Meanwhile, the current findings could enhance doctor-patient discussions about the trade-offs between the two strategies for individuals whose considerations will vary.

“This is a very helpful measure to understand the burden of an approach to the patient,” observed E. Magnus Ohman, MD, an interventional cardiologist at Duke University, Durham, N.C., who was not involved in the trial.

With DAOH as an endpoint, “you as a clinician get another aspect of understanding of a treatment’s impact on a multitude of endpoints.” Days out of hospital, he noted, encompasses the effects of clinical events that often go into composite clinical endpoints – not death, but including nonfatal MI, stroke, need for revascularization, and cardiovascular hospitalization.

To patients with stable CAD who ask whether the invasive approach has merits in their case, the DAOH finding “helps you to say, well, at the end of the day, you will probably be spending an equal amount of time in the hospital. Your price up front is a little bit higher, but over time, the group who gets conservative treatment will catch up.”

The DAOH outcome also avoids the limitations of an endpoint based on time to first event, “not the least of which,” said Dr. White, is that it counts only the first of what might be multiple events of varying clinical impact. Misleadingly, “you can have an event that’s a small troponin rise, but that becomes more important in a person than dying the next day.”

The DAOH analysis was based on 5,179 patients from 37 countries who averaged 64 years of age and of whom 23% were women. The endpoint considered only overnight stays in hospitals, skilled nursing facilities, rehabilitation centers, and nursing homes.

There were many more hospital or extended care facility stays overall in the invasive-management group, 4,002 versus 1,897 for those following the conservative strategy (P < .001), but the numbers flipped after excluding protocol-assigned procedures: 1,568 stays in the invasive group, compared with 1,897 (P = .001)

There were no associations between DAOH and Seattle Angina Questionnaire 7–Angina Frequency scores or DAOH interactions by age, sex, geographic region, or whether the patient had diabetes, prior MI, or heart failure, the report notes.

The primary ISCHEMIA analysis hinted at a possible long-term advantage for the invasive initial strategy in that event curves for the two arms crossed after 2-3 years, Dr. Ohman observed.

Based on that, for younger patients with stable CAD and ischemia at stress testing, “an investment of more hospital days early on might be worth it in the long run.” But ISCHEMIA, he said, “only suggests it, it doesn’t confirm it.”

The study was supported in part by grants from Arbor Pharmaceuticals and AstraZeneca. Devices or medications were provided by Abbott Vascular, Amgen, Arbor, AstraZeneca, Esperion, Medtronic, Merck Sharp & Dohme, Phillips, Omron Healthcare, and Sunovion. Dr. White disclosed receiving grants paid to his institution and fees for serving on a steering committee from Sanofi-Aventis, Regeneron, Eli Lilly, Omthera, American Regent, Eisai, DalCor, CSL Behring, Sanofi-Aventis Australia, and Esperion Therapeutics, and personal fees from Genentech and AstraZeneca. Dr. Ohman reported receiving grants from Abiomed and Cheisi USA, and consulting for Abiomed, Cara Therapeutics, Chiesi USA, Cytokinetics, Imbria Pharmaceuticals, Otsuka Pharmaceuticals, Milestone Pharmaceuticals, and XyloCor Therapeutics.

Operational changes in primary care linked with improved smoking, blood pressure outcomes

Article Type
Changed

 

Operational changes are linked to improvements in smoking and blood pressure outcomes in primary care practice settings, new research indicates.

The qualitative analysis, published in Annals of Family Medicine , included smoking and blood pressure as separate outcome measures.

The outcomes were calculated using Clinical Quality Measure improvements, with targets of at least 10-point absolute improvements in the proportion of patients with smoking screening, if relevant, counseling, and in the proportion of hypertensive patients with adequately controlled BP. The results were obtained from practices participating in Evidence-NOW, a multisite cardiovascular disease prevention initiative. Configurational Comparative Methods were used to evaluate the joint effects of multiple factors on outcomes.

The majority of practices in the analysis were clinician owned, small (fewer than six clinicians), and/or in an urban location. The researchers sampled and interviewed practice staff from a subset of 104 primary care practices across 7 Cooperatives and 12 states, ranging from small to medium in size, having 10 or fewer clinicians. The interview data were analyzed to identify operational changes, then transformed into numeric data.
 

Operational changes led to improvements in specific contexts

In clinician-owned practices, process improvement, documentation, and referral to resources, combined with a moderate level of facilitation support, led to an improvement of at least 10 points in smoking outcomes.

However, the researchers found that these patterns were not observed in system–owned practices or Federally Qualified Health Centers.

In solo practices, training medical assistants to take an accurate blood pressure led to an improvement of at least 10 points in blood pressure outcomes.

Among larger, clinician-owned practices, measurement of blood pressure a second time when the first was elevated, and documentation of this reading in the electronic heath record, also led to a 10-point or greater improvement in BP outcome when combined with a large amount (50 hours or more) of facilitation.

“There was no magic bullet for improving smoking cessation counseling and blood pressure outcomes across the diverse primary care practices studied,” lead author Deborah J. Cohen, PhD, of Oregon Health & Science University, Portland, said in an interview. “Combinations of operational changes among practice sizes and types led to improvements.”
 

Smaller practices more nimble, experts say

Results of the qualitative data analysis suggest that smaller and clinician-owned practices are more likely to have the capacity for change and improvement compared with larger, hospital/health system–owned practices.

Commenting on the study, Noel Deep, MD, regional medical director at Aspirus Clinics, Ironwood, Mich., said solo or small private practices have a distinct advantage over larger hospital or system-owned practices when implementing new operational changes to improve clinical outcomes.

“A smaller independent practice is nimble, with the physician [or physicians] able to make a quick decision at analyzing the scientific data, planning the changes, implementing them quickly, and doing a rapid cycle review of the results and tweaking the program to attain the targets,” said Dr. Deep, a member of the editorial advisory board of Internal Medicine News.

Kate Rowland, MD, MS, assistant professor in the department of family medicine at Rush Medical College, Chicago, also noted that smaller practices have unique advantages over larger health organizations.

“Larger organizations should replicate the benefits of the smaller office, providing as much local decision-making and autonomy as possible to the site where the changes are happening,” Dr. Rowland explained in an interview.

“The clinicians at these sites are mostly likely to know what is going to be successful for achieving measurable change in the patients they care for,” she added.

The study was funded by the Agency for Healthcare Research and Quality. The authors and other experts interviewed for this piece reported having no conflicts of interest.

A ‘mess’ of a diagnosis: Is it type 2 MI or a nonischemic imposter?

Article Type
Changed

Survival gains in the management of acute myocardial infarction in recent decades don’t apply to one increasingly common category of MI.

Type 2 MI, triggered by a surge in myocardial oxygen demand or a drop in its supply, is on the rise and might be more prognostically serious than the “classic” atherothrombotic type 1 form, for which there have been such impressive strides in therapy.

Strategies for assessing and treating type 2 MI and another condition it can resemble clinically – nonischemic myocardial injury – have been less rigorously explored and are far less settled.

That could be partly because recent iterations of the consensus-based universal definition of MI define type 1 MI primarily by the atherothrombotic process, whereas “demand” type 2 MI is characterized as secondary to other disorders. The list of potential primary conditions, cardiac and noncardiac, is long.

As a result, patients with type 1 MI are clinically well defined, but those with type 2 MI have so far defied efforts to be clinically characterized in a consistent way. However, recent efforts might change that, given growing appreciation that all-cause and cardiovascular (CV) mortality outcomes are actually worse for patients with type 2 MI.

“That’s because we have lots of treatments for type 1 MI. Type 2 and myocardial injury? We don’t know how to treat them,” David E. Newby, MD, PhD, University of Edinburgh, said in an interview.

Dr. Newby pointed to a widely cited 2018 publication, of which he is a coauthor, documenting 5-year outcomes of 2,122 patients with type 1 MI, type 2 MI, or nonischemic myocardial injury per the newly minted fourth universal definition.

Risk-factor profiles for patients with the latter two conditions contrasted with those of patients with type 1 MI, he observed. They were “a lot older,” were less likely to be smokers, had more hypertension and previous stroke, and a less prominent CV family history.

“So they’re a different beast,” Dr. Newby said. And their prognosis tended to be worse: all-cause mortality was about 62% for patients with type 2 MI and 72% with nonischemic myocardial injury, but only 37% for patients with type 1 MI. The difference between the two types of infarction was driven by an excess of noncardiovascular death after type 2 MI.

Mortality in patients with type 2 MI is “quite high, but it may well be a marker of the fact that you’ve got other serious diseases on board that are associated with poorer outcome,” he said.
 

Risk varies

The degree of risk in type 2 MI seems to vary with the underlying condition, a recent cohort study suggests. In about 3,800 patients with cardiac troponin (cTn) elevations qualifying as MI – a younger group; most were in their 30s and 40s – mortality at 10 years was 12% for those with type 1 MI, but 34% for those with type 2 MI and 46% for the remainder with nonischemic myocardial injury.

Underlying precipitating conditions varied widely among the patients with type 2 MI or nonischemic myocardial injury, and there was broad variation in mortality by etiology among those with type 2 MI. Sepsis and anemia entailed some of the highest risk, and hypertension and arrhythmias some of the lowest.

A prospective, community-based study of 5,460 patients with type 1 MI or type 2 MI reached a similar conclusion, but with a twist. Five-year all-cause mortality contrasted significantly between types of MI at 31% and 52%, respectively, but CV mortality rates were similar in this study.

Mortality in type 2 MI again varied by the precipitating etiology, suggesting that patients can be risk stratified according to pathophysiological mechanism behind their demand infarction, the authors concluded, “underscoring that type 2 MI is not a single entity, rather a group of phenotypic clusters.”

The usually high comorbidity burden and CV risk in patients with type 2 MI, one of those authors said in an interview, suggest there are “opportunities to see whether we can reduce that risk.”

Formal recommendations consistently say that, in patients with type 2 MI, “your first and foremost target should be to treat the underlying trigger and cause,” said Yader Sandoval, MD, Mayo Clinic, Rochester, Minn. That means such opportunities for further CV risk reduction tend to be “underappreciated.”

“In principle, treating the inciting cause of type 2 MI or the injury is important,” said James L. Januzzi, MD, Massachusetts General Hospital, Boston, in an interview, “but I feel quite strongly that there must be more that we can do for these folks.”

Dr. Januzzi is senior author on a recent analysis based on more than 200,000 admissions across the United States that saw a 43% lower risk for in-hospital death and 54% lower risk for 30-day MI readmission for patients with type 2 MI than those with type 1, adjusted for risk factors and comorbidities.

But, “it is important to emphasize that type 2 MI patients had a substantial risk for adverse outcome, nonetheless, and lack a clear management approach,” Dr. Januzzi and colleagues stated in their publication, as reported by this news organization.

“Due to the high rates of long-term cardiovascular events experienced by the frequently encountered type 2 MI patients,” they wrote, “identifying evidence-based therapies represents a major unmet need.”

That such patients tend to be sick with multiple comorbidities and have not yet been clinically well characterized, Dr. Januzzi said, “has stymied our ability to develop a treatment strategy.”
 

 

 

Role of the universal definitions

That challenge might in some ways be complicated by the universal definition, especially version 4, in which the definitions for type 1 MI, type 2 MI, and nonischemic myocardial injury are unified biochemically.

This version, published in 2018 in the European Heart Journal and Circulation, introduced a formal definition of myocardial injury, which was hailed as an innovation: cTn elevation to the 99th percentile of the upper limit of normal in a reference population.

It differentiates type 1 MI from type 2 MI by the separate pathophysiology of the ischemia – plaque rupture with intracoronary thrombosis and myocardial oxygen supply–demand mismatch, respectively. In both cases, however, there must be symptoms or objective evidence of ischemia. Absent signs of ischemia, the determination would be nonischemic myocardial injury.

Yet clinically and prognostically, type 2 MI and nonischemic myocardial injury in some ways are more similar to each other than either is to type 1 MI. Both occur secondary to other conditions across diverse clinical settings and can be a challenge to tell apart.

The universal definition’s perspective of the three events – so heavily dependent on cTn levels and myocardial ischemia – fails to account for the myriad complexities of individual patients in practice, some say, and so can muddle the process of risk assessment and therapy.

“Abnormal troponin identifies injury, but it doesn’t identify mechanism. Type 2 MI is highly prevalent, but there are other things that cause abnormal troponins,” Dr. Januzzi said. That’s why it’s important to explore and map out the clinical variables associated with the two conditions, to “understand who has a type 2 MI and who has cardiac injury. And believe it or not, it’s actually harder than it sounds to sort that out.”

“Practically speaking, the differentiation between these events is clinical,” Dr. Sandoval agreed. “There’s not always perfect agreement on what we’re calling what.”

Consequently, the universal definitions might categorize some events in ways that seem inconsistent from a management perspective. For example, they make a sharp distinction between coronary atherothrombotic and coronary nonatherothrombotic MI etiologies. Some clinicians would group MI caused by coronary spasm, coronary embolism, or spontaneous coronary artery dissection along with MI from coronary plaque rupture and thrombosis. But, Dr. Sandoval said, “even though these are coronary issues, they would fall into the type 2 bin.”

Also, about half of cases identified as type 2 MI are caused by tachyarrhythmias, which can elevate troponin and cause ECG changes and possibly symptoms resembling angina, Dr. Newby observed. “But that is completely different from other types of myocardial infarction, which are much more serious.”

So, “it’s a real mess of a diagnosis – acute myocardial injury, type 2 and type 1 MI – and it can be quite difficult to disentangle,” he said. “I think that the definition certainly has let us down.”

The diversity of type 2 MI clinical settings might also be a challenge. Myocardial injury according to cTn, with or without ischemia, occurs widely during critical illnesses and acute conditions, including respiratory distress, sepsis, internal bleeding, stroke, and pulmonary embolism.

Early in the COVID-19 pandemic, much was made of elevated troponin levels and myocarditis as an apparently frequent complication among hospitalized patients. “I raised my hand and said, we’ve been seeing abnormal troponins in people with influenza for 20 years,” Dr. Januzzi said. “Critical illness, infection, toxicity from drugs, from chemotherapy, from alcohol – there are all sorts of potential triggers of myocardial injury.”
 

 

 

Troponin ‘overdependence’

With many clinical settings in common and the presence or absence of myocardial ischemia to primarily distinguish them, type 2 MI and nonischemic myocardial injury both can be mistaken for the other. That can send management decisions in inappropriate directions.

A 2019 study looked at 633 cases that had been coded as type 2 MI at a major center and readjudicated them according to the fourth universal definition. Only 57% met all the type 2 criteria, 42% were reclassified as nonischemic myocardial injury, and a few were determined to have unstable angina.

“There’s overdependence on the easiest tool in the universal definition,” said Dr. Januzzi, a coauthor on that study. “Frequently people get seduced by the rise in a troponin value and immediately call it a myocardial infarction, lacking the other components of the universal definition that require evidence for coronary ischemia. That happens every day, where someone with an abnormal troponin is incorrectly branded as having an MI.”

It may not help that the current ICD-10-CM system features a diagnostic code for type 2 MI but not for myocardial injury.

“Instead, the new ICD-10-CM coding includes a proxy called ‘non-MI troponin elevation due to an underlying cause,’ ” wrote Kristian Thygesen, MD, DSc, and Allan S. Jaffe, MD, in a recent editorial. They caution against “using this code for myocardial injury because it is not specific for an elevated cTn value and could represent any abnormal laboratory measurements.” The code could be “misleading,” thereby worsening the potential for miscoding and “misattribution of MI diagnoses.”

That potential suggests there could be a growing population of patients who have been told they had an MI, which then becomes part of their medical record, when, actually, they experienced nonischemic myocardial injury.

“Having seen this occur,” Dr. Januzzi explained, “it affects people emotionally to think they’ve had an MI. Precision in diagnosis is important, which is why the universal definition is so valuable. If people would adhere to it more assiduously, we could reduce the frequency of people getting a misdiagnosis of MI when in fact they had injury.”

Still, he added, “if someone has an illness severe enough to cause myocardial injury, they’re at risk for a bad outcome regardless of whether they did or didn’t have an MI.”
 

The uncertain role of angiography

Angiography isn’t ordered nearly as often for patients ultimately diagnosed with type 2 MI or myocardial injury as for those with type 1 MI. Type 2 MI can hit some patients who have remained symptom free despite possibly unrecognized obstructive coronary artery disease (CAD) when myocardial demand is pushed past supply by a critical illness, tachyarrhythmia, or other acute conditions.

In such cases, “it’s reasonable to hypothesize that revascularization, something that really is not done in the vast majority of patients with type 2 MI, might actually be of benefit,” Dr. Januzzi said.

Whether these patients should routinely have angiography remains an open question. Without intervention, any newly identified obstructive CAD would continue to lurk in the background as a potential threat.

In efforts to differentiate type 2 MI from nonischemic injury, it can be “incredibly hard to know whether or not there’s actual ischemia in the mix. And that’s the only thing that defines the difference before taking an angiogram,” Derek P. Chew, MBBS, MPH, Flinders Medical Centre, Bedford Park, Australia, said in an interview.

Dr. Chew is principal investigator for the ongoing ACT-2 trial that is enrolling hospitalized, hemodynamically stable patients with cTn elevations but no suspicion of type 1 MI and “an unequivocal acute intercurrent diagnosis.” Qualifying diagnoses are prespecified on a list that includes sepsis, pneumonia, septicemia, a systemic inflammatory response, anemia, atrial tachycardia, acute kidney injury, and recent noncardiac surgery.

The patients are randomly assigned to a strategy of routine, usually invasive coronary angiography with discretionary revascularization, or to conservative care with noninvasive functional testing as appropriate. The sicker the patient, the greater the competing risk from other conditions and the less revascularization is likely to improve outcomes, Dr. Chew observed. Importantly, therefore, outcomes in the trial will be stratified by patient risk from comorbidities, measured with baseline GRACE and APACHE III scores.

Dr. Chew said the study aims to determine whether routine angiography is of benefit in patients at some identifiable level of risk, if not the whole range. One possible result, he said, is that there could be a risk-profile “sweet spot” associated with better outcomes in those assigned to angiography.

Enrollment in the trial started about 3 years ago, but “the process has been slow,” he said, because many potentially referring clinicians have a “bias on one side or another,” with about half of them preferring the angiography approach and the other half conservative management.
 

 

 

The unsettled role of drug therapy

With their often-complicated clinical profile, patients with type 2 MI or nonischemic myocardial injury tend to be medically undertreated, yet there is observational evidence they can benefit from familiar drug therapies.

In the previously noted cohort study of 3,800 younger patients with one of the three forms of myocardial injury, less than half of patients with type 2 MI received any form of CAD secondary prevention therapy at discharge, the researchers, with first author Avinainder Singh, MD, from Yale University, New Haven, Conn, wrote.

The finding, consistent with Dr. Newby’s study from 2018, suggests that “categorizing the type of MI in young subjects might inform long-term cardiovascular prognosis,” and “emphasizes the need to identify and implement secondary prevention strategies to mitigate the high rate of cardiovascular death in patients with type 2 MI,” they concluded.

Further, outcomes varied with the number of discharge CV meds in an older cohort of patients with myocardial injury. Those with type 2 MI or acute or chronic nonischemic myocardial injury were far less likely than patients with type 1 MI to be prescribed guideline-based drugs. Survival was greater for those on two or three classes of CV medications, compared with one or none, in patients with acute or chronic nonischemic injury.

The investigators urged that patients with nonischemic myocardial injury or type 2 MI “be treated with cardiovascular medication to a larger degree than what is done today.”

When there is documented CAD in patients with type 2 MI, “it would be reasonable to suggest that preventative secondary prevention approaches, such as such lipid-reduction therapy or aspirin, would be beneficial,” Dr. Sandoval said. “But the reality is, there are no randomized trials, there are no prospective studies. ACT-2 is one of the few and early studies that’s really trying to address this.”

“The great majority of these people are not going to the cath lab, but when they do, there seems to be a signal of potential benefit,” Dr. Januzzi said. “For someone with a type 2 MI, it’s quite possible revascularization might help. Then more long-term treatment with medications that are proven in randomized trials to reduce risk would be a very plausible intervention.”

“We’ve actually proposed a number of potential therapeutic interventions to explore, both in people with type 2 MI and in people with injury without MI,” he said. “They might include sodium glucose cotransporter 2 inhibitors. They might include antithrombotic therapy or more aggressive lipid lowering, possibly for the pleiotropic effects rather than the effects on atherosclerosis.”

Any such therapies that prove successful in well-designed trials could well earn both type 2 MI and nonischemic myocardial injury, neglected as disorders in their own right, the kind of respect in clinical care pathways that they likely deserve.

Survival gains in the management of acute myocardial infarction in recent decades don’t apply to one increasingly common category of MI.

Type 2 MI, triggered by a surge in myocardial oxygen demand or a drop in its supply, is on the rise and might be more prognostically serious than the “classic” atherothrombotic type 1 form, for which there have been such impressive strides in therapy.

Strategies for assessing and treating type 2 MI and another condition it can resemble clinically – nonischemic myocardial injury – have been less rigorously explored and are far less settled.

That could be partly because recent iterations of the consensus-based universal definition of MI define type 1 MI primarily by the atherothrombotic process, whereas “demand” type 2 MI is characterized as secondary to other disorders. The list of potential primary conditions, cardiac and noncardiac, is long.

As a result, patients with type 1 MI are clinically well defined, but those with type 2 MI have so far defied efforts to be clinically characterized in a consistent way. However, recent efforts might change that, given growing appreciation that all-cause and cardiovascular (CV) mortality outcomes are actually worse for patients with type 2 MI.

“That’s because we have lots of treatments for type 1 MI. Type 2 and myocardial injury? We don’t know how to treat them,” David E. Newby, MD, PhD, University of Edinburgh, said in an interview.

Dr. Newby pointed to a widely cited 2018 publication, of which he is a coauthor, documenting 5-year outcomes of 2,122 patients with type 1 MI, type 2 MI, or nonischemic myocardial injury per the newly minted fourth universal definition.

Risk-factor profiles for patients with the latter two conditions contrasted with those of patients with type 1 MI, he observed. They were “a lot older,” were less likely to be smokers, had more hypertension and previous stroke, and a less prominent CV family history.

“So they’re a different beast,” Dr. Newby said. And their prognosis tended to be worse: all-cause mortality was about 62% for patients with type 2 MI and 72% with nonischemic myocardial injury, but only 37% for patients with type 1 MI. The difference between the two types of infarction was driven by an excess of noncardiovascular death after type 2 MI.

Mortality in patients with type 2 MI is “quite high, but it may well be a marker of the fact that you’ve got other serious diseases on board that are associated with poorer outcome,” he said.

In about 3,800 patients with cardiac troponin (cTn) elevations qualifying as MI – a younger group; most were in their 30s and 40s – mortality at 10 years was 12% for those with type 1 MI, but 34% for those with type 2 MI and 46% for the remainder with nonischemic myocardial injury.

Underlying precipitating conditions varied widely among the patients with type 2 MI or nonischemic myocardial injury, and there was broad variation in mortality by etiology among those with type 2 MI. Sepsis and anemia entailed some of the highest risk, and hypertension and arrhythmias some of the lowest.

A prospective, community-based study of 5,460 patients with type 1 MI or type 2 MI reached a similar conclusion, but with a twist. Five-year all-cause mortality contrasted significantly between types of MI at 31% and 52%, respectively, but CV mortality rates were similar in this study.

Mortality in type 2 MI again varied by the precipitating etiology, suggesting that patients can be risk stratified according to pathophysiological mechanism behind their demand infarction, the authors concluded, “underscoring that type 2 MI is not a single entity, rather a group of phenotypic clusters.”

The usually high comorbidity burden and CV risk in patients with type 2 MI, one of those authors said in an interview, suggest there are “opportunities to see whether we can reduce that risk.”

Formal recommendations consistently say that, in patients with type 2 MI, “your first and foremost target should be to treat the underlying trigger and cause,” said Yader Sandoval, MD, Mayo Clinic, Rochester, Minn. That means such opportunities for further CV risk reduction tend to be “underappreciated.”

Dr. James L. Januzzi

“In principle, treating the inciting cause of type 2 MI or the injury is important,” said James L. Januzzi, MD, Massachusetts General Hospital, Boston, in an interview, “but I feel quite strongly that there must be more that we can do for these folks.”

Dr. Januzzi is senior author on a recent analysis based on more than 200,000 admissions across the United States that saw a 43% lower risk for in-hospital death and 54% lower risk for 30-day MI readmission for patients with type 2 MI than those with type 1, adjusted for risk factors and comorbidities.

But, “it is important to emphasize that type 2 MI patients had a substantial risk for adverse outcome, nonetheless, and lack a clear management approach,” Dr. Januzzi and colleagues stated in their publication, as reported by this news organization.

“Due to the high rates of long-term cardiovascular events experienced by the frequently encountered type 2 MI patients,” they wrote, “identifying evidence-based therapies represents a major unmet need.”

That such patients tend to be sick with multiple comorbidities and have not yet been clinically well characterized, Dr. Januzzi said, “has stymied our ability to develop a treatment strategy.”
 

 

 

Role of the universal definitions

That challenge might in some ways be complicated by the universal definition, especially version 4, in which the definitions for type 1 MI, type 2 MI, and nonischemic myocardial injury are unified biochemically.

This version, published in 2018 in the European Heart Journal and Circulation, introduced a formal definition of myocardial injury, which was hailed as an innovation: cTn elevation to the 99th percentile of the upper limit of normal in a reference population.

It differentiates type 1 MI from type 2 MI by the separate pathophysiology of the ischemia – plaque rupture with intracoronary thrombosis and myocardial oxygen supply–demand mismatch, respectively. In both cases, however, there must be symptoms or objective evidence of ischemia. Absent signs of ischemia, the determination would be nonischemic myocardial injury.

Yet clinically and prognostically, type 2 MI and nonischemic myocardial injury in some ways are more similar to each other than either is to type 1 MI. Both occur secondary to other conditions across diverse clinical settings and can be a challenge to tell apart.

The universal definition’s perspective of the three events – so heavily dependent on cTn levels and myocardial ischemia – fails to account for the myriad complexities of individual patients in practice, some say, and so can muddle the process of risk assessment and therapy.

“Abnormal troponin identifies injury, but it doesn’t identify mechanism. Type 2 MI is highly prevalent, but there are other things that cause abnormal troponins,” Dr. Januzzi said. That’s why it’s important to explore and map out the clinical variables associated with the two conditions, to “understand who has a type 2 MI and who has cardiac injury. And believe it or not, it’s actually harder than it sounds to sort that out.”

“Practically speaking, the differentiation between these events is clinical,” Dr. Sandoval agreed. “There’s not always perfect agreement on what we’re calling what.”

Consequently, the universal definitions might categorize some events in ways that seem inconsistent from a management perspective. For example, they make a sharp distinction between coronary atherothrombotic and coronary nonatherothrombotic MI etiologies. Some clinicians would group MI caused by coronary spasm, coronary embolism, or spontaneous coronary artery dissection along with MI from coronary plaque rupture and thrombosis. But, Dr. Sandoval said, “even though these are coronary issues, they would fall into the type 2 bin.”

Also, about half of cases identified as type 2 MI are caused by tachyarrhythmias, which can elevate troponin and cause ECG changes and possibly symptoms resembling angina, Dr. Newby observed. “But that is completely different from other types of myocardial infarction, which are much more serious.”

So, “it’s a real mess of a diagnosis – acute myocardial injury, type 2 and type 1 MI – and it can be quite difficult to disentangle,” he said. “I think that the definition certainly has let us down.”

The diversity of type 2 MI clinical settings might also be a challenge. Myocardial injury according to cTn, with or without ischemia, occurs widely during critical illnesses and acute conditions, including respiratory distress, sepsis, internal bleeding, stroke, and pulmonary embolism.

Early in the COVID-19 pandemic, much was made of elevated troponin levels and myocarditis as an apparently frequent complication among hospitalized patients. “I raised my hand and said, we’ve been seeing abnormal troponins in people with influenza for 20 years,” Dr. Januzzi said. “Critical illness, infection, toxicity from drugs, from chemotherapy, from alcohol – there are all sorts of potential triggers of myocardial injury.”
 

 

 

Troponin ‘overdependence’

With many clinical settings in common and the presence or absence of myocardial ischemia to primarily distinguish them, type 2 MI and nonischemic myocardial injury both can be mistaken for the other. That can send management decisions in inappropriate directions.

A 2019 study looked at 633 cases that had been coded as type 2 MI at a major center and readjudicated them according to the fourth universal definition. Only 57% met all the type 2 criteria, 42% were reclassified as nonischemic myocardial injury, and a few were determined to have unstable angina.

“There’s overdependence on the easiest tool in the universal definition,” said Dr. Januzzi, a coauthor on that study. “Frequently people get seduced by the rise in a troponin value and immediately call it a myocardial infarction, lacking the other components of the universal definition that require evidence for coronary ischemia. That happens every day, where someone with an abnormal troponin is incorrectly branded as having an MI.”

It may not help that the current ICD-10-CM system features a diagnostic code for type 2 MI but not for myocardial injury.

“Instead, the new ICD-10-CM coding includes a proxy called ‘non-MI troponin elevation due to an underlying cause,’ ” wrote Kristian Thygesen, MD, DSc, and Allan S. Jaffe, MD, in a recent editorial. They caution against “using this code for myocardial injury because it is not specific for an elevated cTn value and could represent any abnormal laboratory measurements.” The code could be “misleading,” thereby worsening the potential for miscoding and “misattribution of MI diagnoses.”

That potential suggests there could be a growing population of patients who have been told they had an MI, which then becomes part of their medical record, when, actually, they experienced nonischemic myocardial injury.

“Having seen this occur,” Dr. Januzzi explained, “it affects people emotionally to think they’ve had an MI. Precision in diagnosis is important, which is why the universal definition is so valuable. If people would adhere to it more assiduously, we could reduce the frequency of people getting a misdiagnosis of MI when in fact they had injury.”

Still, he added, “if someone has an illness severe enough to cause myocardial injury, they’re at risk for a bad outcome regardless of whether they did or didn’t have an MI.”
 

The uncertain role of angiography

Angiography isn’t ordered nearly as often for patients ultimately diagnosed with type 2 MI or myocardial injury as for those with type 1 MI. Type 2 MI can hit some patients who have remained symptom free despite possibly unrecognized obstructive coronary artery disease (CAD) when myocardial demand is pushed past supply by a critical illness, tachyarrhythmia, or other acute conditions.

In such cases, “it’s reasonable to hypothesize that revascularization, something that really is not done in the vast majority of patients with type 2 MI, might actually be of benefit,” Dr. Januzzi said.

Whether these patients should routinely have angiography remains an open question. Without intervention, any newly identified obstructive CAD would continue to lurk in the background as a potential threat.

In efforts to differentiate type 2 MI from nonischemic injury, it can be “incredibly hard to know whether or not there’s actual ischemia in the mix. And that’s the only thing that defines the difference before taking an angiogram,” Derek P. Chew, MBBS, MPH, Flinders Medical Centre, Bedford Park, Australia, said in an interview.

Dr. Chew is principal investigator for the ongoing ACT-2 trial that is enrolling hospitalized, hemodynamically stable patients with cTn elevations but no suspicion of type 1 MI and “an unequivocal acute intercurrent diagnosis.” Qualifying diagnoses are prespecified on a list that includes sepsis, pneumonia, septicemia, a systemic inflammatory response, anemia, atrial tachycardia, acute kidney injury, and recent noncardiac surgery.

The patients are randomly assigned to a strategy of routine, usually invasive coronary angiography with discretionary revascularization, or to conservative care with noninvasive functional testing as appropriate. The sicker the patient, the greater the competing risk from other conditions and the less revascularization is likely to improve outcomes, Dr. Chew observed. Importantly, therefore, outcomes in the trial will be stratified by patient risk from comorbidities, measured with baseline GRACE and APACHE III scores.

Dr. Chew said the study aims to determine whether routine angiography is of benefit in patients at some identifiable level of risk, if not the whole range. One possible result, he said, is that there could be a risk-profile “sweet spot” associated with better outcomes in those assigned to angiography.

Enrollment in the trial started about 3 years ago, but “the process has been slow,” he said, because many potentially referring clinicians have a “bias on one side or another,” with about half of them preferring the angiography approach and the other half conservative management.
 

 

 

The unsettled role of drug therapy

With their often-complicated clinical profile, patients with type 2 MI or nonischemic myocardial injury tend to be medically undertreated, yet there is observational evidence they can benefit from familiar drug therapies.

In the previously noted cohort study of 3,800 younger patients with one of the three forms of myocardial injury, less than half of patients with type 2 MI received any form of CAD secondary prevention therapy at discharge, the researchers, with first author Avinainder Singh, MD, from Yale University, New Haven, Conn, wrote.

The finding, consistent with Dr. Newby’s study from 2018, suggests that “categorizing the type of MI in young subjects might inform long-term cardiovascular prognosis,” and “emphasizes the need to identify and implement secondary prevention strategies to mitigate the high rate of cardiovascular death in patients with type 2 MI,” they concluded.

Further, outcomes varied with the number of discharge CV meds in an older cohort of patients with myocardial injury. Those with type 2 MI or acute or chronic nonischemic myocardial injury were far less likely than patients with type 1 MI to be prescribed guideline-based drugs. Survival was greater for those on two or three classes of CV medications, compared with one or none, in patients with acute or chronic nonischemic injury.

The investigators urged that patients with nonischemic myocardial injury or type 2 MI “be treated with cardiovascular medication to a larger degree than what is done today.”

When there is documented CAD in patients with type 2 MI, “it would be reasonable to suggest that preventative secondary prevention approaches, such as such lipid-reduction therapy or aspirin, would be beneficial,” Dr. Sandoval said. “But the reality is, there are no randomized trials, there are no prospective studies. ACT-2 is one of the few and early studies that’s really trying to address this.”

“The great majority of these people are not going to the cath lab, but when they do, there seems to be a signal of potential benefit,” Dr. Januzzi said. “For someone with a type 2 MI, it’s quite possible revascularization might help. Then more long-term treatment with medications that are proven in randomized trials to reduce risk would be a very plausible intervention.”

“We’ve actually proposed a number of potential therapeutic interventions to explore, both in people with type 2 MI and in people with injury without MI,” he said. “They might include sodium glucose cotransporter 2 inhibitors. They might include antithrombotic therapy or more aggressive lipid lowering, possibly for the pleiotropic effects rather than the effects on atherosclerosis.”

Any such therapies that prove successful in well-designed trials could well earn both type 2 MI and nonischemic myocardial injury, neglected as disorders in their own right, the kind of respect in clinical care pathways that they likely deserve.

Dr. Newby has disclosed receiving consulting fees or honoraria from Eli Lilly, Roche, Toshiba, Jansen, Reckitt Benckiser Pharmaceuticals, Pfizer, AstraZeneca, Bristol-Myers Squibb, GlaxoSmithKline, CellProthera, and Oncoarendi; and conducting research or receiving grants from Pfizer, AstraZeneca, Bristol-Myers Squibb, GlaxoSmithKline, Merck, Boehringer Ingelheim, and Inositec. Sandoval reports serving on an advisory board and as a speaker for Abbott Diagnostics and on an advisory board for Roche Diagnostics. Dr. Januzzi has disclosed receiving grant support from Novartis, Applied Therapeutics, and Innolife; consulting for Abbott Diagnostics, Janssen, Novartis, Quidel, and Roche Diagnostics; and serving on endpoint committees or data safety monitoring boards for trials supported by Abbott, AbbVie, Amgen, CVRx, Janssen, MyoKardia, and Takeda. Dr. Chew has reported receiving grants from AstraZeneca and Edwards Life Sciences. ACT-2 is sponsored by the National Medical and Health Research Council of Australia.

Finerenone scores second pivotal-trial success in patients with diabetic kidney disease

Article Type
Changed

Finerenone, an investigational agent from a new drug class, just scored a second pivotal trial win after showing significant benefit for slowing progression of diabetic kidney disease in patients with type 2 diabetes in the FIDELIO-DKD pivotal trial with more than 5,700 patients.

Top-line results from FIGARO-DKD showed significant benefit for the primary endpoint of cardiovascular death and nonfatal cardiovascular disease endpoints in a placebo-controlled trial with about 7,400 patients with type 2 diabetes, reported Bayer, the company developing finerenone in statement released on May 10, 2021.

Based on the FIDELIO-DKD results, finerenone is currently under review by the U.S. Food and Drug Administration for marketing approval as a treatment for patients with type 2 diabetes and chronic kidney disease. FIDELIO-DKD, in addition to the primary endpoint that focused on slowing progression of diabetic kidney disease, had a secondary endpoint that assessed the combined incidence on treatment of cardiovascular death, or nonfatal episodes of stroke, MI, or hospitalization for heart failure. Results from the study published in 2020 in the New England Journal of Medicine showed that finerenone was safe and effective for both endpoints.



In the current study, FIGARO-DKD, run at more than 1,000 sites in 47 countries, these endpoints flipped. The primary outcome was a composite of cardiovascular death or nonfatal cardiovascular disease events, and the secondary outcome was prevention of DKD progression.

Other than stating the results significantly fulfilled FIGARO-DKD’s primary endpoint of reducing the incidence of combined cardiovascular disease endpoints, the release gave no further outcome details. The release noted that the enrolled patient cohort in FIGARO-DKD included more patients with earlier-stage chronic kidney disease, compared with FIDELIO-DKD.

Finerenone is a first-in-class investigational nonsteroidal, selective mineralocorticoid receptor antagonist (MRA). As an MRA it shares certain activities with the steroidal MRAs spironolactone and eplerenone. But the absence of a steroidal structure means that finerenone does not cause steroidal adverse effects such as gynecomastia. Results in FIDELIO-DKD showed that finerenone caused more hyperkalemia than placebo, but the level of hyperkalemia that it causes relative to spironolactone or eplerenone remains uncertain.

Possible obesity effect detected in cancer death rates

Article Type
Changed

The obesity epidemic in the United States may be slowing improvements in cancer mortality, according to a new analysis of over 50 million cancer and heart disease deaths.

“By integrating 20 years of cancer mortality data, we demonstrated that trends in obesity-associated cancer mortality showed signs of recent deceleration, consistent with recent findings for heart disease mortality,” Christy L. Avery, PhD, and associates wrote in JAMA Network Open.

Improvements in mortality related to heart disease slowed after 2011, a phenomenon that has been associated with rising obesity rates. The age-adjusted mortality rate (AAMR) declined at an average of 3.8 deaths per 100,000 persons from 1999 to 2011 but only 0.7 deaths per 100,000 from 2011 to 2018, based on data from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research (WONDER).

To understand trends in cancer mortality and their possible connection with obesity, data for 1999-2018 from the WONDER database were divided into obesity-associated and non–obesity-associated categories and compared with heart disease mortality, they explained. The database included more than 50 million deaths that matched inclusion criteria.

The analysis showed there was difference between obesity-associated and non–obesity-associated cancers that was obscured when all cancer deaths were considered together. The average annual change in AAMR for obesity-associated cancers slowed from –1.19 deaths per 100,000 in 1999-2011 to –0.83 in 2011-2018, Dr. Avery and associates reported.

For non–obesity-associated cancers, the annual change in AAMR increased from –1.62 per 100,000 for 1999-2011 to –2.29 for 2011-2018, following the trend for all cancers: –1.48 per 100,000 during 1999-2011 and –1.77 in 2011-2018, they said.

“The largest mortality decreases were observed for melanoma of the skin and lung cancer, two cancers not associated with obesity. For obesity-associated cancers, stable or increasing mortality rates have been observed for liver and pancreatic cancer among both men and women as well as for uterine cancer among women,” the investigators wrote.

Demographically, however, the slowing improvement in mortality for obesity-associated cancers did not follow the trend for heart disease. The deceleration for cancer was more pronounced for women and for non-Hispanic Whites and not seen at all in non-Hispanic Asian/Pacific Islander individuals. “For heart disease, evidence of a deceleration was consistent across sex, race, and ethnicity,” they said.

There are “longstanding disparities in obesity” among various populations in the United States, and the recent trend of obesity occurring earlier in life may be having an effect. “Whether the findings of decelerating mortality rates potentially signal a changing profile of cancer and heart disease mortality as the consequences of the obesity epidemic are realized remains to be seen,” they concluded.

The investigators reported receiving grants from the National Institutes of Health during the conduct of the study, but no other disclosures were reported.

A simple new definition for ‘metabolically healthy obesity’?

Article Type
Changed

 

Scientists have proposed a simple new definition for “metabolically healthy obesity” to identify individuals who do not have an increased risk of cardiovascular disease (CVD) death and total mortality.

The team – led by Anika Zembic, MPH, German Institute of Human Nutrition Potsdam-Rehbruecke, Nuthetal, Germany – performed an assessment of anthropometric and metabolic risk factors as well as mortality data from two cohorts that “yielded a simple definition to categorize participants with obesity as metabolically healthy or unhealthy.”

They defined “metabolically healthy” as systolic blood pressure <130 mm Hg and no use of blood pressure-lowering medication; waist-to-hip ratio <0.95 (in women) and <1.03 (in men); and no prevalent type 2 diabetes.

Based on this new definition, 42% of participants in the third U.S. National Health and Nutrition Examination Survey (NHANES-III) and 19% of participants in the UK Biobank study had metabolically healthy obesity and did not have an increased risk for CVD mortality and total mortality compared with individuals with metabolically healthy normal weight.  

“People with a phenotype defined as metabolically unhealthy using this definition had significantly higher hazard ratios for [CVD] mortality and total mortality irrespective of body mass index category, and people with phenotypes defined as having metabolically healthy obesity displayed no increased risk,” the researchers noted in their article, published May 7 in JAMA Network Open.

“Our new definition may be important not only to stratify risk of mortality in people with obesity, but also in people with overweight and normal weight,” they concluded.
 

Thirty different definitions of ‘metabolically healthy obesity’

“To date, there is no universally accepted standard for defining [metabolically healthy obesity] and more than 30 different definitions have been used to operationalize the phenotypes in studies,” which may explain the “continued unresolved debate” about outcomes in patients with metabolically unhealthy obesity, Ayana K. April-Sanders, PhD, and Carlos J. Rodriguez, MD, MPH, from Albert Einstein College of Medicine, New York, wrote in an accompanying commentary.

The current study, they noted, suggests that waist-to-hip ratio is a better measure of central adiposity than waist circumference, and that the effect of dyslipidemia on CVD mortality may be weaker among individuals with obesity.

However, the findings may not be generalizable to other CVD outcomes, they cautioned.

And importantly, some individuals with metabolically healthy obesity will likely transition to unhealthy obesity over time due to weight gain, aging, and lack of physical activity.

Therefore, “the present study provides a prototype of how that definition can be derived, but more rigorous tests and evidence using similar techniques are needed, particularly in prospective studies,” according to Dr. April-Sanders and Dr. Rodriguez.

They call for more research to establish a standardized definition of metabolically healthy obesity and then, using that definition, to determine the prevalence of healthy and unhealthy obesity and identify factors that preserve healthy obesity. 
 

Definition developed from NHANES cohort, validated in UK biobank

Ms. Zembic and colleagues explained that previous definitions for metabolically healthy obesity were mainly based on the absence of either metabolic syndrome or insulin resistance, but some individuals with obesity but without metabolic disease still have increased risks of CVD mortality and total mortality.

To develop a more precise definition of metabolically healthy obesity, the researchers analyzed data from 12,341 individuals in the United States who participated in NHANES-III, conducted between 1988 and 1994. The individuals were a mean age of 42 and 51% were women, and they were followed for an average of 14.5 years.  

The researchers validated this definition using data from 374,079 individuals in the population-based UK Biobank cohort who were assessed in 2006 to 2010. Those individuals were a mean age of 56 and 55% were women, and they were followed for a mean of 7.8 years.

The combination of systolic blood pressure and waist-to-hip ratio had the strongest association with CVD mortality and total mortality, and the prevalence of type 2 diabetes was also associated with greater risk.

Regardless of BMI, all groups of metabolically unhealthy individuals had increased risks of CVD mortality and total mortality.

The study and some of the researchers were supported by grants from the German Federal Ministry of Education and Research.

Scientists have proposed a simple new definition for “metabolically healthy obesity” to identify individuals who do not have an increased risk of cardiovascular disease (CVD) death and total mortality.

The team – led by Anika Zembic, MPH, German Institute of Human Nutrition Potsdam-Rehbruecke, Nuthetal, Germany – performed an assessment of anthropometric and metabolic risk factors as well as mortality data from two cohorts that “yielded a simple definition to categorize participants with obesity as metabolically healthy or unhealthy.”

They defined “metabolically healthy” as systolic blood pressure <130 mm Hg and no use of blood pressure-lowering medication; waist-to-hip ratio <0.95 (in women) and <1.03 (in men); and no prevalent type 2 diabetes.

Based on this new definition, 42% of participants in the third U.S. National Health and Nutrition Examination Survey (NHANES-III) and 19% of participants in the UK Biobank study had metabolically healthy obesity and did not have an increased risk for CVD mortality and total mortality compared with individuals with metabolically healthy normal weight.  

“People with a phenotype defined as metabolically unhealthy using this definition had significantly higher hazard ratios for [CVD] mortality and total mortality irrespective of body mass index category, and people with phenotypes defined as having metabolically healthy obesity displayed no increased risk,” the researchers noted in their article, published May 7 in JAMA Network Open.

“Our new definition may be important not only to stratify risk of mortality in people with obesity, but also in people with overweight and normal weight,” they concluded.

Infective endocarditis with stroke after TAVR has ‘dismal’ prognosis

Article Type
Changed

 

Patients who suffer a stroke during hospitalization for infective endocarditis (IE) after transcatheter aortic valve replacement (TAVR) have a dismal prognosis, with more than half dying during the index hospitalization and two-thirds within the first year, a new study shows.

The study – the first to evaluate stroke as an IE-related complication following TAVR in a large multicenter cohort – is published in the May 11 issue of the Journal of the American College of Cardiology.

The authors, led by David del Val, MD, Quebec Heart & Lung Institute, Quebec City, explain that IE after TAVR is a rare but serious complication associated with a high mortality rate. Neurologic events, especially stroke, remain one of the most common and potentially disabling IE-related complications, but until now, no study has attempted to evaluate the predictors of stroke and outcomes in patients with IE following TAVR.

For the current study, the authors analyzed data from the Infectious Endocarditis after TAVR International Registry, including 569 patients who developed definite IE following TAVR from 59 centers in 11 countries.

Patients who experienced a stroke during IE admission were compared with patients who did not have a stroke.

Results showed that 57 patients (10%) had a stroke during IE hospitalization, with no differences in the causative microorganism between groups. Stroke patients had higher rates of acute renal failure, systemic embolization, and persistent bacteremia.

Factors associated with a higher risk for stroke during the index IE hospitalization included stroke before IE, moderate or higher residual aortic regurgitation after TAVR, balloon-expandable valves, IE within 30 days after TAVR, and vegetation size greater than 8 mm.

The stroke rate was 3.1% in patients with none of these risk factors; 6.1% with one risk factor; 13.1% with two risk factors; 28.9% with three risk factors, and 60% with four risk factors.

“The presence of such factors (particularly in combination) may be considered for determining an earlier and more aggressive (medical or surgical) treatment in these patients,” the researchers say.

IE patients with stroke had higher rates of in-hospital mortality (54.4% vs. 28.7%) and overall mortality at 1 year (66.3% vs. 45.6%).

Surgery rates were low (25%) even in the presence of stroke and failed to improve outcomes in this population.

Noting that consensus guidelines for managing patients with IE recommend surgery along with antibiotic treatment for patients developing systemic embolism, particularly stroke, the researchers say their findings suggest that such surgery recommendations may not be extrapolated to TAVR-IE patients, and specific guidelines are warranted for this particular population.

Furthermore, the possibility of early surgery in those patients with factors increasing the risk for stroke should be evaluated in future studies.

The authors note that TAVR has revolutionized the treatment of aortic stenosis and is currently moving toward less complex and younger patients with lower surgical risk. Despite the relatively low incidence of IE after TAVR, the number of procedures is expected to grow exponentially, increasing the number of patients at risk of developing this life-threatening complication. Therefore, detailed knowledge of this disease and its complications is essential to improve outcomes.

They point out that the 10% rate of stroke found in this study is substantially lower, compared with the largest surgical prosthetic-valve infective endocarditis registries, but they suggest that the unique clinical profile of TAVR patients may lead to an underdiagnosis of stroke, with a high proportion of elderly patients who more frequently present with nonspecific symptoms.

They conclude that “IE post-TAVR is associated with a poor prognosis with high in-hospital and late mortality rates. Our study reveals that patients with IE after TAVR complicated by stroke showed an even worse prognosis.”

“The progressive implementation of advanced imaging modalities for early IE diagnosis, especially nuclear imaging, may translate into a better prognosis in coming years. Close attention should be paid to early recognition of stroke-associated factors to improve clinical outcomes,” they add.

In an accompanying editorial, Vuyisile Nkomo, MD, Daniel DeSimone, MD, and William Miranda, MD, Mayo Clinic, Rochester, Minn., say the current study “highlights the devastating consequences of IE after TAVR and the even worse consequences when IE was associated with stroke.”

This points to the critical importance of efforts to prevent IE with appropriate antibiotic prophylaxis and addressing potential sources of infection (for example, dental screening) before invasive cardiac procedures.

“Patient education is critical in regard to recognizing early signs and symptoms of IE. In particular, patients must be informed to obtain blood cultures with any episode of fever, as identification of bacteremia is critical in the diagnosis of IE,” the editorialists comment.  

Endocarditis should also be suspected in afebrile patients with increasing transcatheter heart valve gradients or new or worsening regurgitation, they state.

Multimodality imaging is important for the early diagnosis of IE to facilitate prompt antibiotic treatment and potentially decrease the risk for IE complications, especially systemic embolization, they add.

“Despite the unequivocal advances in the safety and periprocedural complications of TAVR, IE with and without stroke in this TAVR population remains a dreadful complication,” they conclude.

Dr. Del Val was supported by a research grant from the Fundación Alfonso Martin Escudero. The editorialists have disclosed no relevant financial relationships.

VARC-3 sets goalpost for future aortic valve trials

Article Type
Changed

 

The newly updated Valve Academic Research Consortium 3 (VARC-3) definitions and endpoints proposed for transcatheter and surgical aortic valve replacement (TAVR/SAVR) research aim to add more granularity and a patient focus to a rapidly evolving field, the authors say.

Work began in 2016 to update definitions in the document to be more contemporary, as TAVR matured over the last 10 years to include younger, lower-risk patients and began moving to long-term outcomes, lead author Philippe Généreux, MD, said in an interview.

“The main change in VARC-3 is really that we tried to define not only procedural outcome, both for TAVR and aortic valve replacement performed by surgery, but also more the long-term outcomes mainly based on the patient – so quality of life, bioprosthetic valve failure, how do we define a valve failure, and also the need for rehospitalization,” he said.

However, soon after the VARC-3 document was published on April 19, 2021, in the European Heart Journal and Journal of the American College of Cardiology, surgeons took to social media to highlight the writing committee’s financial ties to industry and to suggest some definitions were shaped to favor transcatheter approaches.

“There’s no doubt that the coauthors who participated in these guidelines are experts; nobody would argue about that but what we can argue, and I’m 100% sure about, is that we have experts outside the payroll of industry who are excellent and can be part of this guideline drafting in an unbiased way,” Victor Dayan, MD, adjunct professor of cardiac surgery, National Institute of Cardiac Surgery, Montevideo, Uruguay, said in an interview.

Although the American College of Physicians recommends guideline committee members with moderate- or high-level conflicts of interest recuse themselves from authorship, he noted that one author has received more than $2 million in fees from industry in the past 4-5 years.

In all, 20 of 23 authors were involved in PARTNER, SURTAVI, and PORTICO, and several also write clinical guidelines for the American College of Cardiology and American Heart Association. “So we have the same authors that are judge, jury, and attorney for these issues,” Dr. Dayan said.

In a comment, J. Rafael Sádaba, MD, PhD, interim secretary general for the European Association for Cardio-Thoracic Surgery, pointed out that only three committee members are surgeons and that author disclosures took up nearly a full page of the document. “Surely they would be able to find very capable physicians with far less conflicts of interest.”

Dr. Sádaba said the question to him is why professional societies like ACC and AHA don’t define the endpoints for the clinical trials that will inform their guidelines.

“One could say these people are there because they’re good scientists, trialists, but one at least has to ask why is this happening. Why are these people setting the rules for the trials they’re running?” said Dr. Sádaba, of the Royal Navarre Hospital, Pamplona, Spain.

Dr. Généreux dismissed the Twitter comments as coming from a handful of people who engage in conspiracy theories. The VARC-3 document, he said, was created with input from 75 experts, including Food and Drug Administration officials, and the final document was reviewed by the FDA and underwent rigorous peer review prior to publication.

“The question is: do you believe there is bias when people are involved in studies driven by the industry? Well, this is where we derive our science in this field,” he said. “We are very transparent and disclose our conflicts of interest [COI].”

Commenting further, Dr. Généreux added, “this was a very well-balanced group and to imply that because we work with industry, we don’t have the best interest of the patient in mind is wrong.”

Editor in chief of the EHJ, Filippo Crea, MD, PhD, Catholic University, Rome, said in an comment that “it is not surprising that most of the authors have experience in TAVR trials. All of the authors have carefully disclosed their COIs.”

He noted that the EHJ and JACC copublished the first VARC consensus in 2011, VARC-2 1 year later, and that VARC-3 was reviewed by four external reviewers and two editors and was accepted for publication after two revisions.

Asked about a shot on social media that the EHJ had long ago “sold its soul” to be the scientific “arm” of industry, Dr. Crea said allegations need to be substantiated by facts.

“The wide adoption of VARC definitions implies that they have been well accepted by the scientific community and that they have stood the test of time,” Dr. Crea said. “EHJ has a history of publishing high-quality science. We welcome robust arguments that may challenge previously published work. Readers who perceive gaps are encouraged to provide a detailed challenge and engage with the journal.”
 

 

 

Defining hospitalizations

One of the surgeons’ biggest concerns is that VARC-3 now defines hospitalization or rehospitalization as “any admission after the index hospitalization or study enrollment” for at least 24 hours, including an ED stay.

VARC-2 and SURTAVI defined hospitalizations as those for valve-related symptoms or worsening heart failure, whereas the newly reformulated definition of hospitalization was part of the main composite endpoint in the PARTNER-3 trial, along with stroke and mortality, that drove the superiority of TAVR over SAVR at 1 year for low-risk patients, Dr. Dayan noted.

“It’s not uncommon for patients who have cardiac surgery to come back for issues related to wound healing or mild pulmonary edema for a day or 2, and if you include these hospitalizations in the primary endpoint, it will dilute the real benefit of SAVR versus TAVR, which is mortality and stroke,” he added.

In choosing the broader definition, Dr. Généreux said they borrowed from heart failure studies that take a granular approach and account for every hospitalization, be it for a medication change or adjustment. “We cannot pick and choose which hospitalization we are going to consider or ignore.”

VARC-3 proposes criteria for identifying and diagnosing hypoattenuated leaflet thickening (HALT) and reduced leaflet motion and features a detailed chart of the new classification scheme for bioprosthetic valve dysfunction and failure.

Bioprosthetic valve dysfunction includes structural valve deterioration, nonstructural valve dysfunction (including abnormalities not intrinsic to the valve such as paravalvular regurgitation or prosthesis-patient mismatch), thrombosis, and endocarditis. VARC-3 proposes a five-class grading system for paravalvular regurgitation (mild, mild-moderate, moderate, moderate-severe, severe).

The document updates what the authors called a “previously vague definition” of valve thrombosis proposed in 2011 to now include “clinically significant” prosthetic valve thrombosis. This requires clinical sequelae of a thromboembolic event (stroke, transient ischemic attack, retinal occlusion, or other evidence of thromboembolism) or worsening valve stenosis/regurgitation and either hemodynamic valve deterioration stage 2 or 3 or confirmatory imaging (CT evidence of HALT or transesophageal echocardiographic findings). In the absence of symptoms/clinical sequelae, valve thrombosis (subclinical) can be diagnosed if there is hemodynamic valve deterioration stage 3 and confirmatory imaging.

Bioprosthetic valve failure is divided into three stages, with stage 1 taking into account clinical factors along with valve dysfunction, stage 2 being reintervention, and stage 3 being valve-related death.

“For us, bioprosthesis valve failure is not only the need for reintervention, but it’s also mortality, it’s also a significant increase in gradient or the occurrence of paravalvular leak,” said Dr. Généreux, of the Morristown (N.J.) Medical Center. “So it’s much more clinical.”
 

Stroke, myocardial infarction

VARC-3 provides detailed definitions of neurologic events and, in an attempt to harmonize with the Neurologic Academic Research Consortium, recommends combining assessment of neurologic symptoms with tissue-based criteria (pathology or neuroimaging, ideally diffusion-weighted MRI) to define stroke and other central nervous system injury.

It also recommends that assessment be performed 30-90 days after a neurologic event and that assessment of neurologic deficits for cerebral embolic protection trials be performed by a neurologist.

VARC-3 endorses the fourth Universal Definition of Myocardial Infarction for MI types 1-3, 4B, and 4C.

For periprocedural MI after percutaneous coronary intervention (PCI), coronary bypass graft surgery, TAVR, and SAVR, however, it endorses the modified Society for Cardiovascular Angiography and Interventions and Academic Research Consortium-2 definition, which uses troponin or creatine kinase-MB thresholds.

“Given that most current and future studies related to AVR strategies will involve long-term follow-up, with patients frequently suffering from coronary artery disease, VARC-3 believes that these definitions will allow the most appropriate characterization and classification of types of MI occurring in this population,” the committee wrote.

The decision comes after last year’s controversy surrounding the Abbott-sponsored EXCEL trial, which used a modified version of the SCAI definition for periprocedural MI as part of its primary composite endpoint of death, stroke, and MI.

Initial reports showed nearly twice the rate of periprocedural MI with cardiac surgery as with PCI, but after a BBC investigation involving leaked data and an onslaught of criticism from surgeons, later results using the third universal definition showed surgery had the advantage.

The debacle frayed relations between surgeons and interventionalists and prompted EACTS to withdraw its support for treatment recommendations for left main coronary artery disease.

Dr. Dayan applauded VARC-3 for incorporating more detailed information on stroke and neurologic events, but said the use of the SCAI definition in the final published document is in “total disregard” to the controversy generated among surgeons and interventionalists.

“The main concern for surgeons is defining periprocedural MI just by biochemical definitions, without any additional criteria like ECG, angiographic,” he said. “This is totally new and goes against what surgeons have been advocating for years around EXCEL.”

Dr. Sádaba was troubled by the definitions of MI and hospitalization, but also questioned other changes, like lumping vascular complications together with access-related complications. “The sense is a lot of what they’ve put here favors one type of intervention over the other.”

Dr. Généreux reported receiving consultant fees from Abbott Vascular, Abiomed, Boston Scientific, Cardinal Health, Cardiovascular System, Edwards Lifesciences, Medtronic, Opsens, Siemens, SoundBite Medical Solutions, Sig.Num, Saranas, Teleflex, Tryton Medical, and has equity in Pi-Cardia, Sig.Num, SoundBite Medical Solutions, Saranas, and Puzzle Medical. Dr. Crea reported receiving personal fees from Novartis, Bristol-Myers Squibb, Amgen, and AstraZeneca, and is a member of the advisory board of GlyCardial Diagnostics. Dr. Dayan and Dr. Sádaba reported no relevant conflicts of interest.

The newly updated Valve Academic Research Consortium 3 (VARC-3) definitions and endpoints proposed for transcatheter and surgical aortic valve replacement (TAVR/SAVR) research aim to add more granularity and a patient focus to a rapidly evolving field, the authors say.

Work began in 2016 to update definitions in the document to be more contemporary, as TAVR matured over the last 10 years to include younger, lower-risk patients and began moving to long-term outcomes, lead author Philippe Généreux, MD, said in an interview.

“The main change in VARC-3 is really that we tried to define not only procedural outcome, both for TAVR and aortic valve replacement performed by surgery, but also more the long-term outcomes mainly based on the patient – so quality of life, bioprosthetic valve failure, how do we define a valve failure, and also the need for rehospitalization,” he said.

However, soon after the VARC-3 document was published on April 19, 2021, in the European Heart Journal and Journal of the American College of Cardiology, surgeons took to social media to highlight the writing committee’s financial ties to industry and to suggest some definitions were shaped to favor transcatheter approaches.

“There’s no doubt that the coauthors who participated in these guidelines are experts; nobody would argue about that but what we can argue, and I’m 100% sure about, is that we have experts outside the payroll of industry who are excellent and can be part of this guideline drafting in an unbiased way,” Victor Dayan, MD, adjunct professor of cardiac surgery, National Institute of Cardiac Surgery, Montevideo, Uruguay, said in an interview.

Although the American College of Physicians recommends guideline committee members with moderate- or high-level conflicts of interest recuse themselves from authorship, he noted that one author has received more than $2 million in fees from industry in the past 4-5 years.

In all, 20 of 23 authors were involved in PARTNER, SURTAVI, and PORTICO, and several also write clinical guidelines for the American College of Cardiology and American Heart Association. “So we have the same authors that are judge, jury, and attorney for these issues,” Dr. Dayan said.

In a comment, J. Rafael Sádaba, MD, PhD, interim secretary general for the European Association for Cardio-Thoracic Surgery, pointed out that only three committee members are surgeons and that author disclosures took up nearly a full page of the document. “Surely they would be able to find very capable physicians with far less conflicts of interest.”

Dr. Sádaba said the question to him is why professional societies like ACC and AHA don’t define the endpoints for the clinical trials that will inform their guidelines.

“One could say these people are there because they’re good scientists, trialists, but one at least has to ask why is this happening. Why are these people setting the rules for the trials they’re running?” said Dr. Sádaba, of the Royal Navarre Hospital, Pamplona, Spain.

Dr. Généreux dismissed the Twitter comments as coming from a handful of people who engage in conspiracy theories. The VARC-3 document, he said, was created with input from 75 experts, including Food and Drug Administration officials, and the final document was reviewed by the FDA and underwent rigorous peer review prior to publication.

“The question is: do you believe there is bias when people are involved in studies driven by the industry? Well, this is where we derive our science in this field,” he said. “We are very transparent and disclose our conflicts of interest [COI].”

Commenting further, Dr. Généreux added, “this was a very well-balanced group and to imply that because we work with industry, we don’t have the best interest of the patient in mind is wrong.”

Editor in chief of the EHJ, Filippo Crea, MD, PhD, Catholic University, Rome, said in an comment that “it is not surprising that most of the authors have experience in TAVR trials. All of the authors have carefully disclosed their COIs.”

He noted that the EHJ and JACC copublished the first VARC consensus in 2011, VARC-2 1 year later, and that VARC-3 was reviewed by four external reviewers and two editors and was accepted for publication after two revisions.

Asked about a shot on social media that the EHJ had long ago “sold its soul” to be the scientific “arm” of industry, Dr. Crea said allegations need to be substantiated by facts.

“The wide adoption of VARC definitions implies that they have been well accepted by the scientific community and that they have stood the test of time,” Dr. Crea said. “EHJ has a history of publishing high-quality science. We welcome robust arguments that may challenge previously published work. Readers who perceive gaps are encouraged to provide a detailed challenge and engage with the journal.”
 

 

 

Defining hospitalizations

One of the surgeons’ biggest concerns is that VARC-3 now defines hospitalization or rehospitalization as “any admission after the index hospitalization or study enrollment” for at least 24 hours, including an ED stay.

VARC-2 and SURTAVI defined hospitalizations as those for valve-related symptoms or worsening heart failure, whereas the newly reformulated definition of hospitalization was part of the main composite endpoint in the PARTNER-3 trial, along with stroke and mortality, that drove the superiority of TAVR over SAVR at 1 year for low-risk patients, Dr. Dayan noted.

“It’s not uncommon for patients who have cardiac surgery to come back for issues related to wound healing or mild pulmonary edema for a day or 2, and if you include these hospitalizations in the primary endpoint, it will dilute the real benefit of SAVR versus TAVR, which is mortality and stroke,” he added.

In choosing the broader definition, Dr. Généreux said they borrowed from heart failure studies that take a granular approach and account for every hospitalization, be it for a medication change or adjustment. “We cannot pick and choose which hospitalization we are going to consider or ignore.”

VARC-3 proposes criteria for identifying and diagnosing hypoattenuated leaflet thickening (HALT) and reduced leaflet motion and features a detailed chart of the new classification scheme for bioprosthetic valve dysfunction and failure.

Bioprosthetic valve dysfunction includes structural valve deterioration, nonstructural valve dysfunction (including abnormalities not intrinsic to the valve such as paravalvular regurgitation or prosthesis-patient mismatch), thrombosis, and endocarditis. VARC-3 proposes a five-class grading system for paravalvular regurgitation (mild, mild-moderate, moderate, moderate-severe, severe).

The document updates what the authors called a “previously vague definition” of valve thrombosis proposed in 2011 to now include “clinically significant” prosthetic valve thrombosis. This requires clinical sequelae of a thromboembolic event (stroke, transient ischemic attack, retinal occlusion, or other evidence of thromboembolism) or worsening valve stenosis/regurgitation and either hemodynamic valve deterioration stage 2 or 3 or confirmatory imaging (CT evidence of HALT or transesophageal echocardiographic findings). In the absence of symptoms/clinical sequelae, valve thrombosis (subclinical) can be diagnosed if there is hemodynamic valve deterioration stage 3 and confirmatory imaging.

Bioprosthetic valve failure is divided into three stages, with stage 1 taking into account clinical factors along with valve dysfunction, stage 2 being reintervention, and stage 3 being valve-related death.

Nutritional support may be lifesaving in heart failure

Article Type
Changed

Personalized nutritional support for adults hospitalized with chronic heart failure and deemed to be at high nutritional risk reduced the risk of death or adverse cardiovascular events, compared with standard hospital food, new research indicates.
 

The Swiss EFFORT trial focused on patients with chronic heart failure and high risk of malnutrition defined by low body mass index, weight loss, and low food intake upon hospital admission.

“This high-risk group of chronic heart failure patients showed a significant improvement in mortality over 30 and 180 days, as well as other clinical outcomes, when individualized nutritional support interventions were offered to patients,” Philipp Schuetz, MD, MPH, Kantonsspital Aarau, Switzerland, said in an interview.

“While monitoring the nutritional status should be done also in outpatient settings by [general practitioners], malnutrition screening upon hospital admission may help to identify high-risk patients with high risk for nutritional status deterioration during the hospital stay who will benefit from nutritional assessment and treatment,” said Dr. Schuetz.

The study was published online May 3 in the Journal of the American College of Cardiology.
 

It’s not all about salt

The findings are based on a prespecified secondary analysis of outcomes in 645 patients (median age, 78.8 years, 52% men) hospitalized with chronic heart failure who participated in the open-label EFFORT study.  

One-third of patients were hospitalized for acute decompensated heart failure and two-thirds had chronic heart failure and other acute medical illnesses requiring hospitalization.

All patients were at risk of malnutrition based on a Nutritional Risk Screening (NRS) score of 3 points or higher. They were randomly allocated 1:1 to individualized nutritional support to reach energy, protein, and micronutrient goals or usual hospital food (control group). 

By 30 days, 27 of 321 patients (8.4%) receiving nutritional support had died compared with 48 of 324 patients (14.8%) in the control group (adjusted odds ratio [OR]: 0.44; 95% confidence interval, 0.26-0.75; P = .002)

Patients with high nutritional risk (NRS >4 points) showed the most benefit from nutritional support.

Compared with patients with moderate nutritional risk scores (NRS score 3-4), those with high nutritional risk (NRS >4) had a highly significant 65% increased mortality risk over 180 days.

The individual component of the NRS with the strongest association with mortality was low food intake in the week before hospitalization.

Patients who received nutritional support in the hospital also had a lower risk for major cardiovascular events at 30 days (17.4% vs. 26.9%; OR, 0.50; 95% CI, 0.34-0.75; P = .001).

“Historically, cardiologists and internists caring for patients with heart failure have mainly focused on salt-restrictive diets to reduce blood volume and thus optimize heart function. Yet, reduction of salt intake has not been shown to effectively improve clinical outcome but may, on the contrary, increase the risk of malnutrition as low-salt diets are often not tasty,” Dr. Schuetz said.

“Our data suggest that we should move our focus away from salt-restrictive diets to high-protein diets to cover individual nutritional goals in this high-risk group of patients, which includes screening, assessment, and nutritional support by dietitians,” Dr. Schuetz said.

In a linked editorial, Sheldon Gottlieb, MD, Johns Hopkins University, Baltimore, said there has been “relatively little attention” paid to the role of diet in heart failure other than recommending reduced salt intake. 

In fact, in the 2021 American College of Cardiology expert consensus recommendations for optimizing heart failure treatment, roughly five words are devoted to diet and exercise and there is no mention of nutrition assessment by a dietitian, he points out.

“This study adds another tile to the still-fragmentary mosaic picture of the patient with heart failure at nutritional risk who might benefit from nutritional support,” Dr. Dr. Gottlieb wrote.

“ ‘Good medical care’ dictates that all hospitalized patients deserve to have a standardized nutritional assessment; the challenge remains: how to determine which patient with heart failure at nutritional risk will benefit by medical nutrition therapy,” Dr. Gottlieb said.

The Swiss National Science Foundation and the Research Council of the Kantonsspital Aarau provided funding for the trial. Dr. Schuetz’s institution has previously received unrestricted grant money unrelated to this project from Nestle Health Science and Abbott Nutrition. Dr. Gottlieb owns a federal trademark for the “Greens, Beans, and Leans” diet, and has a pending federal trademark for “FLOATS”: flax + oats cereal.

“This high-risk group of chronic heart failure patients showed a significant improvement in mortality over 30 and 180 days, as well as other clinical outcomes, when individualized nutritional support interventions were offered to patients,” Philipp Schuetz, MD, MPH, Kantonsspital Aarau, Switzerland, said in an interview.

“While monitoring the nutritional status should be done also in outpatient settings by [general practitioners], malnutrition screening upon hospital admission may help to identify high-risk patients with high risk for nutritional status deterioration during the hospital stay who will benefit from nutritional assessment and treatment,” said Dr. Schuetz.

The study was published online May 3 in the Journal of the American College of Cardiology.
 

It’s not all about salt

The findings are based on a prespecified secondary analysis of outcomes in 645 patients (median age, 78.8 years, 52% men) hospitalized with chronic heart failure who participated in the open-label EFFORT study.  

One-third of patients were hospitalized for acute decompensated heart failure and two-thirds had chronic heart failure and other acute medical illnesses requiring hospitalization.

All patients were at risk of malnutrition based on a Nutritional Risk Screening (NRS) score of 3 points or higher. They were randomly allocated 1:1 to individualized nutritional support to reach energy, protein, and micronutrient goals or usual hospital food (control group). 

By 30 days, 27 of 321 patients (8.4%) receiving nutritional support had died compared with 48 of 324 patients (14.8%) in the control group (adjusted odds ratio [OR]: 0.44; 95% confidence interval, 0.26-0.75; P = .002)

Patients with high nutritional risk (NRS >4 points) showed the most benefit from nutritional support.

Compared with patients with moderate nutritional risk scores (NRS score 3-4), those with high nutritional risk (NRS >4) had a highly significant 65% increased mortality risk over 180 days.

The individual component of the NRS with the strongest association with mortality was low food intake in the week before hospitalization.

Patients who received nutritional support in the hospital also had a lower risk for major cardiovascular events at 30 days (17.4% vs. 26.9%; OR, 0.50; 95% CI, 0.34-0.75; P = .001).

“Historically, cardiologists and internists caring for patients with heart failure have mainly focused on salt-restrictive diets to reduce blood volume and thus optimize heart function. Yet, reduction of salt intake has not been shown to effectively improve clinical outcome but may, on the contrary, increase the risk of malnutrition as low-salt diets are often not tasty,” Dr. Schuetz said.

“Our data suggest that we should move our focus away from salt-restrictive diets to high-protein diets to cover individual nutritional goals in this high-risk group of patients, which includes screening, assessment, and nutritional support by dietitians,” Dr. Schuetz said.

In a linked editorial, Sheldon Gottlieb, MD, Johns Hopkins University, Baltimore, said there has been “relatively little attention” paid to the role of diet in heart failure other than recommending reduced salt intake. 

In fact, in the 2021 American College of Cardiology expert consensus recommendations for optimizing heart failure treatment, roughly five words are devoted to diet and exercise and there is no mention of nutrition assessment by a dietitian, he points out.

“This study adds another tile to the still-fragmentary mosaic picture of the patient with heart failure at nutritional risk who might benefit from nutritional support,” Dr. Dr. Gottlieb wrote.

“ ‘Good medical care’ dictates that all hospitalized patients deserve to have a standardized nutritional assessment; the challenge remains: how to determine which patient with heart failure at nutritional risk will benefit by medical nutrition therapy,” Dr. Gottlieb said.

The Swiss National Science Foundation and the Research Council of the Kantonsspital Aarau provided funding for the trial. Dr. Schuetz’s institution has previously received unrestricted grant money unrelated to this project from Nestle Health Science and Abbott Nutrition. Dr. Gottlieb owns a federal trademark for the “Greens, Beans, and Leans” diet, and has a pending federal trademark for “FLOATS”: flax + oats cereal.

Hypertension worsened by commonly used prescription meds

Article Type
Changed

 

Nearly one out of five American adults with hypertension is on a prescription drug known to raise blood pressure, based on analysis of more than 27,000 people included in recent reports from the recurring National Health and Nutrition Examination Survey (NHANES).

Dr. John Vitarello

Nearly half of these American adults had hypertension, and in this subgroup, 18.5% reported using a prescription drug known to increase blood pressure. The most widely used class of agents with this effect was antidepressants, used by 8.7%; followed by nonsteroidal anti-inflammatory drugs (NSAIDs), used by 6.5%; steroids, 1.9%; estrogens, 1.7%; and several other agents each used by fewer than 1% of the study cohort, John Vitarello, MD, said during a press briefing on reports from the upcoming annual scientific sessions of the American College of Cardiology.

He and his associates estimated that this use of prescription drugs known to raise blood pressure could be what stands in the way of some 560,000-2.2 million Americans from having their hypertension under control, depending on the exact blood pressure impact that various pressure-increasing drugs have and presuming that half of those on blood pressure increasing agents could stop them and switch to alternative agents, said Dr. Vitarello, a researcher at Beth Israel Deaconess Medical Center in Boston.

He also highlighted that the study assessed only prescription drugs and did not examine OTC drug use, which may be especially relevant for the many people who regularly take NSAIDs.

“Clinicians should review the prescription and OTC drug use of patients with hypertension and consider stopping drugs that increase blood pressure or switching the patient to alternatives” that are blood pressure neutral, Dr. Vitarello said during the briefing. He cautioned that maintaining hypertensive patients on agents that raise their blood pressure can result in “prescribing cascades” where taking drugs that boost blood pressure results in need for intensified antihypertensive treatment.
 

An opportunity for NSAID alternatives

“This study hopefully raises awareness that there is a very high use of medications that increase blood pressure, and use of OTC agents could increase the rate even higher” said Eugene Yang, MD, a cardiologist and codirector of the Cardiovascular Wellness and Prevention Program of the University of Washington, Seattle. Substituting for certain antidepressant agents may often not be realistic, but an opportunity exists for reducing NSAID use, a class also linked with an increased risk for bleeding and other adverse effects, Dr. Yang said during the briefing. Minimizing use of NSAIDs including ibuprofen and naproxen use “is something to think about,” he suggested.

“The effect of NSAIDs on blood pressure is not well studied and can vary from person to person” noted Dr. Vitarello, who added that higher NSAID dosages and more prolonged use likely increase the risk for an adverse effect on blood pressure. One reasonable option is to encourage patients to use an alternative class of pain reliever such as acetaminophen.

It remains “a challenge” to discern differences in adverse blood pressure effects, and in all adverse cardiovascular effects among different NSAIDs, said Dr. Yang. Results from “some studies show that certain NSAIDs may be safer, but other studies did not. We need to be very careful using NSAIDs because, on average, they increase blood pressure by about 3 mm Hg. We need to be mindful to try to prescribe alternative agents, like acetaminophen.”
 

A decade of data from NHANES

The analysis run by Dr. Vitarello and associates used data from 27,599 American adults included in the NHANES during 2009-2018, and focused on the 44% who either had an average blood pressure measurement of at least 130/80 mm Hg or reported having ever been told by a clinician that they had hypertension. The NHANES assessments included the prescription medications taken by each participant. The prevalence of using at least one prescription drug known to raise blood pressure was 24% among women and 14% among men, and 4% of those with hypertension were on two or more pressure-increasing agents.

The researchers based their identification of pressure-increasing prescription drugs on the list included in the 2017 guideline for managing high blood pressure from the American College of Cardiology and American Heart Association. This list specifies that the antidepressants that raise blood pressure are the monoamine oxidase inhibitors, serotonin norepinephrine reuptake inhibitors, and tricyclic antidepressants.
