Patients with atopic dermatitis (AD) had a lower risk for major adverse cardiovascular events (MACE) than the general population, and this risk was significantly lower than that of patients with rheumatoid arthritis (RA), according to an analysis of national claims data.

The results of the analysis were presented during a poster session at the Revolutionizing Atopic Dermatitis conference in Chicago. “While it is known that atopic dermatitis is associated with some comorbidities, the specific risk of major adverse cardiovascular events in patients with AD, especially those with moderate to severe AD within the US population, is unclear,” the study’s first author Christopher G. Bunick, MD, PhD, said in an interview following the conference.

To characterize the risk for MACE in patients with AD vs matched controls without AD (non-AD) and patients with RA, Dr. Bunick, associate professor of dermatology at Yale University, New Haven, Connecticut, and colleagues retrospectively evaluated US claims data from Optum’s Clinformatics Data Mart. The study population consisted of 381,221 patients aged 18 years and older who were diagnosed with AD from March 2017 to March 2023. Comparator groups included 381,221 non-AD controls matched by age, sex, and cohort entry, and 97,445 patients diagnosed with RA based on at least two claims for RA ≥ 7 days apart.

Patients were classified as having moderate to severe disease if they received dupilumab for AD or advanced systemic therapy for RA at any time during the follow-up period. The matched moderate to severe AD and non-AD cohorts were composed of 7134 patients each. The incidence of MACE was defined as inpatient hospitalization with myocardial infarction or stroke. The researchers used multivariable Cox proportional hazard models adjusted for baseline demographics, comorbidities, and medications to calculate the relative risk for MACE.
 

MACE Incidence, Relative Risk

The mean age of the AD cohort and non-AD matched controls was 58 years, and the mean age of the RA cohort was 67 years. The incidence of MACE per 100 patient-years was 1.78 among patients with AD, 1.83 among non-AD matched controls, and 2.12 among patients with RA. Patients with moderate to severe AD had a MACE incidence of 1.18 per 100 patient-years, which was lower than that of non-AD matched controls (1.52) and patients with moderate to severe RA (1.67).

In other findings, the relative risk for MACE in patients with AD was lower vs non-AD controls (adjusted hazard ratio [aHR], 0.91; 95% CI, 0.89-0.93; P < .001) and patients with RA (aHR, 0.83; 95% CI, 0.80-0.85; P < .001). Among patients with moderate to severe AD, MACE risk was similar to that of non-AD matched controls (aHR, 0.92; 95% CI, 0.73-1.14) and lower vs those with moderate to severe RA (aHR, 0.83; 95% CI, 0.73-0.94; P < .01).

MACE risk associated with AD was greater in patients who were older (per year, aHR, 1.05; 95% CI, 1.05-1.05), male (aHR, 0.81; 95% CI, 0.79-0.84), and Black vs White (aHR, 1.16; 95% CI, 1.11-1.21), and among those who received systemic corticosteroids in the 3 months before diagnosis (aHR, 1.10; 95% CI, 1.06-1.14), were hospitalized in the year before diagnosis (aHR, 1.35; 95% CI, 1.30-1.41), and had a history of smoking (aHR, 1.20; 95% CI, 1.16-1.24) and drug abuse (aHR, 1.34; 95% CI, 1.25-1.43).
 

Unexpected Results

“One surprising finding was that the incidence of MACE in patients with moderate to severe AD was actually lower than that in non-AD matched controls and significantly lower compared to patients with moderate to severe RA,” Dr. Bunick said. “This contrasts with the expectation that increased systemic inflammation in moderate to severe AD would correspond with a higher incidence of MACE.”

Another unexpected result, he said, was that, among patients with moderate to severe AD, the risk for MACE was not significantly different from that of non-AD matched controls, suggesting that the inflammatory burden in AD might not translate to as high a cardiovascular risk as previously assumed.

Dr. Bunick noted that advanced treatments for AD such as Janus kinase (JAK) inhibitors (upadacitinib and abrocitinib) have a class boxed warning for MACE based on a study of another JAK inhibitor (tofacitinib) in patients with RA, but “this may not apply to AD because patients with AD have a lower risk for MACE.”

In his opinion, he said, the study “underscores the importance of understanding the specific risks associated with different inflammatory conditions.” Moreover, “it emphasizes the potential benefits of newer systemic therapies in potentially mitigating cardiovascular risks in patients with moderate to severe AD.”

Dr. Bunick acknowledged certain limitations of the study, including its retrospective design and reliance on administrative claims data, which “may introduce coding errors and misclassification,” and the generalizability of the results, which may be limited to the US population.

AbbVie funded the study, and three of the coauthors are employees of the company. Dr. Bunick disclosed that he has served as an investigator and/or a consultant for AbbVie, Almirall, Apogee, Arcutis Biotherapeutics, Connect Biopharma, Daiichi Sankyo, EPI Health/Novan, LEO, Lilly, Novartis, Ortho Dermatologics, Palvella Therapeutics, Pfizer, Sanofi Regeneron, Sun, Takeda, Timber, and UCB.

Hi. I’m Dr Eileen Hsich. I’m the medical director for heart transplantation at the Cleveland Clinic, and my specialty is sex differences in heart failure. I’m excited to talk to you about heart failure treatment in women, addressing the differences in managing heart failure in women as well as practical tips for clinicians. You think that I’m going to be starting off by telling you about the differences in how we’re going to manage the patients, but I’m not. The reason I’m not going to do that is because our national guidelines are not sex specific.

What I’m really going to discuss with you today are the data so that you can decide for yourself what we should do and whether there really are differences. As we begin, I always think about the prevalence of the disease. Currently, there are 6.7 million Americans with heart failure, and approximately 45% of them are women. Globally, our best research shows that there are over 56 million people living with heart failure, and half of them are women.

We also know that there are different underlying causes in women and men. For women, the four risk factors are hypertension, diabetes, atrial fibrillation (AFib), and left bundle branch block. I know you knew about hypertension. Diabetes may not have been right up there in your mind. You see many women with AFib, so I know that you were thinking about it. We’re going to come back to left bundle branch block; it really is very interesting.

For men, it is the risk for heart failure development after a myocardial infarction. Men are more likely to have an ischemic cardiomyopathy. It is also important to state that when women have heart failure, it is often with more preserved ejection fraction. We know that heart failure with preserved ejection fraction (HFpEF) is more common in women and heart failure with reduced ejection fraction (HFrEF) is more common in men.

Now we’re going to talk about the four pillars in medical management, and we’re going to start out with the easy medications that show no sex differences in benefit. The mineralocorticoid receptor antagonists (MRAs) show that there are no sex differences in regard to benefit. Women benefit as much as men, based on two of the largest studies, which were the RALES study, which studied heart failure that was ischemic and nonischemic, and then the EPHESUS study, which was specific to patients who had myocardial infarction. There was a mortality benefit in the women.

The next set of drugs that we’re going to mention are the sodium-glucose cotransporter 2 (SGLT2) inhibitors. The combined endpoint for women and men was a combined endpoint of death and heart failure hospitalization. No matter what the ejection fraction was, women benefited like men for this drug.

The third class of agents that I want to discuss is the beta-blockers, which are really very interesting because they’re so powerful. The studies for these drugs were stopped prematurely. When you take into consideration that women are underenrolled in clinical trials, remember that the studies for these drugs were stopped, so there weren’t that many women. The fact that we showed a mortality benefit is really important.

The first drug that we’re going to refer to is bisoprolol because CIBIS II was the first trial for this drug to demonstrate a mortality benefit in women and men. The second drug that I want to mention is metoprolol XL, which did not demonstrate a mortality benefit in the MERIT-HF study, but did demonstrate a benefit in reduced heart failure hospitalizations, which is also very important.

The third drug is carvedilol, which had been shown to reduce a combined endpoint of mortality and heart failure hospitalizations for patients with moderate symptoms. When I talk about these studies, they have anywhere from 250 to 1000 women enrolled, so these are relatively small studies and they still did demonstrate a benefit.

When we talk about angiotensin receptor–neprilysin inhibitors (ARNI), I think that’s when it gets a little complex. The data are not very clear because ARNI is a combination pill — sacubitril combined with valsartan. When you have an ideal control for a study and you want to know what your magic ingredient is, which is the sacubitril, you really want to compare valsartan with ARNI so that you can find out what your magic little ingredient is doing.

When we had the PARAGON-HF study, which was for HFpEF patients who had an ejection fraction greater than 45%, there was a benefit in the women and not in the men, and that really was in the women with the lower ejection fractions. That’s very interesting because the control was valsartan.

When we had the PARADIGM-HF study, that was more complex. The control was an angiotensin-converting enzyme (ACE) inhibitor, which is not an ideal control for women since, even in a meta-analysis that had over 1000 women, there has not been a proven benefit. The confidence intervals remain wide. Therefore, it’s not quite a fair comparison to randomize women to ARNI versus an ACE inhibitor. Comparing ARNI to valsartan would be better in order to determine the additional benefit of sacubitril since valsartan alone has already been shown, in the Val-HeFT study, to reduce heart failure hospitalizations in women — although not mortality. There was a benefit.

When you look at the PARADIGM-HF study, which was for HFrEF patients, and you see that there is a benefit in the women, where the combined endpoint was heart failure hospitalization and mortality, you then see that there’s a figure that shows what happens when we look at mortality alone. The benefit is not driven by mortality; it’s driven by heart failure hospitalizations for the women, for which valsartan already had been shown to do this. Therefore, I don’t know if sacubitril/valsartan is more powerful because we didn’t have the right control in studies. From my standpoint, the data really are not there. We can all have our own biased opinions.

When we talk about devices, that gets really interesting because it goes back to those risk factors. We’re going to start with implantable cardioverter defibrillators (ICDs). We have shown in many ICD trials that women and men had similar survival. There were very few women in these device trials. If you think the medical trials had only a few women, just imagine what the ICD trials had.

Santangeli and colleagues hypothesized that an ICD only saves you from sudden death. It doesn›t really save you from anything else. In heart failure, women do live longer than men. Is this device really saving you? They weren’t interested in all-cause mortality; they were interested in whether the device fired appropriately for ventricular tachycardia or ventricular fibrillation. They demonstrated in that meta-analysis that it was not very clear that women had the benefit. The rationale behind that comes from the MADIT studies that showed that men were more likely than women to have ventricular arrhythmias.

This is also true based on the Seattle Heart Failure Model. The derivation cohort had very few ICDs at that time, and women were less likely than men to have ventricular arrhythmias as the cause of death. It’s not that we shouldn’t put them in — I very strongly believe that we should — but we don’t have that data.

In fact, in the Santangeli and colleagues study, women were more likely to have inappropriate firing for AFib. Remember that we talked about how one of the risk factors for heart failure was AFib. Women are more likely to have AFib and the ICD firing for AFib and not ventricular arrhythmias. This may be dependent on the type of cardiomyopathy.

Next, we’re going to talk about biventricular pacemakers. Women tend to benefit more so that there is an improvement in symptoms and survival. What is fascinating is that left bundle branch block is a risk factor for the development of heart failure in women, which makes this next statement even more fascinating.

The FDA does their own analysis when they are reviewing devices and everything else, and they published one of them in JAMA Internal Medicine, taking three studies and seeing the benefit in women and men. They found that everybody benefits when the left bundle branch block has a QRS greater than 150 milliseconds. But with a QRS between 130 and 149 milliseconds, only the women benefited. That›s fascinating because that is a risk factor — the development of the left bundle branch block causing heart failure in women. It makes you wonder whether you are correcting something that actually was responsible for their heart failure.

In advanced heart failure, we have left ventricular assist devices (LVADs) and heart transplantation. For years, we couldn’t get LVADs small enough to fit in women. When they were larger, there were complications that were more common in women, such as stroke. With the newer devices — the HeartMate 3 is small, for instance — complications for everyone are very infrequent, and women and men benefit. I’m going to encourage clinicians to use them.

For heart transplantation, as I mentioned before, women tend to get HFpEF. I didn’t mention that they get heart failure when they’re older, for the most part. There are fewer women who are transplanted than men and eligible at younger ages. What we had for decades was that women were dying while they were on the waitlist for heart transplantation at a faster rate than men but living longer after transplantation. As LVADs became more appropriately sized for women, the complication rates went down; and we did see an improvement on the waitlist mortality rate before we changed the allocation system. But it really wasn’t until after we changed the allocation system in 2018 that we saw great success. Now, women have similar survival while on the waitlist. They’re transplanted at a faster rate despite the fact that they’re less likely to receive the temporary mechanical support, and they tend to still do very well.

I’ll leave you with the thought that women and men are different. We have different underlying diseases, different onset for the development of heart failure, and different ejection fractions in instances when heart failure develops. We have some differences in therapy response. Thank you.

When we talk about devices, that gets really interesting because it goes back to those risk factors. We’re going to start with implantable cardioverter defibrillators (ICDs). We have shown in many ICD trials that women and men had similar survival. There were very few women in these device trials. If you think the medical trials had only a few women, just imagine what the ICD trials had.

Santangeli and colleagues hypothesized that an ICD only saves you from sudden death. It doesn›t really save you from anything else. In heart failure, women do live longer than men. Is this device really saving you? They weren’t interested in all-cause mortality; they were interested in whether the device fired appropriately for ventricular tachycardia or ventricular fibrillation. They demonstrated in that meta-analysis that it was not very clear that women had the benefit. The rationale behind that comes from the MADIT studies that showed that men were more likely than women to have ventricular arrhythmias.

This is also true based on the Seattle Heart Failure Model. The derivation cohort had very few ICDs at that time, and women were less likely than men to have ventricular arrhythmias as the cause of death. It’s not that we shouldn’t put them in — I very strongly believe that we should — but we don’t have that data.

In fact, in the Santangeli and colleagues study, women were more likely to have inappropriate firing for AFib. Remember that we talked about how one of the risk factors for heart failure was AFib. Women are more likely to have AFib and the ICD firing for AFib and not ventricular arrhythmias. This may be dependent on the type of cardiomyopathy.

Next, we’re going to talk about biventricular pacemakers. Women tend to benefit more so that there is an improvement in symptoms and survival. What is fascinating is that left bundle branch block is a risk factor for the development of heart failure in women, which makes this next statement even more fascinating.

The FDA does their own analysis when they are reviewing devices and everything else, and they published one of them in JAMA Internal Medicine, taking three studies and seeing the benefit in women and men. They found that everybody benefits when the left bundle branch block has a QRS greater than 150 milliseconds. But with a QRS between 130 and 149 milliseconds, only the women benefited. That›s fascinating because that is a risk factor — the development of the left bundle branch block causing heart failure in women. It makes you wonder whether you are correcting something that actually was responsible for their heart failure.

In advanced heart failure, we have left ventricular assist devices (LVADs) and heart transplantation. For years, we couldn’t get LVADs small enough to fit in women. When they were larger, there were complications that were more common in women, such as stroke. With the newer devices — the HeartMate 3 is small, for instance — complications for everyone are very infrequent, and women and men benefit. I’m going to encourage clinicians to use them.

For heart transplantation, as I mentioned before, women tend to get HFpEF. I didn’t mention that they get heart failure when they’re older, for the most part. There are fewer women who are transplanted than men and eligible at younger ages. What we had for decades was that women were dying while they were on the waitlist for heart transplantation at a faster rate than men but living longer after transplantation. As LVADs became more appropriately sized for women, the complication rates went down; and we did see an improvement on the waitlist mortality rate before we changed the allocation system. But it really wasn’t until after we changed the allocation system in 2018 that we saw great success. Now, women have similar survival while on the waitlist. They’re transplanted at a faster rate despite the fact that they’re less likely to receive the temporary mechanical support, and they tend to still do very well.

I’ll leave you with the thought that women and men are different. We have different underlying diseases, different onset for the development of heart failure, and different ejection fractions in instances when heart failure develops. We have some differences in therapy response. Thank you.

Hi. I’m Dr Eileen Hsich. I’m the medical director for heart transplantation at the Cleveland Clinic, and my specialty is sex differences in heart failure. I’m excited to talk to you about heart failure treatment in women, addressing the differences in managing heart failure in women as well as practical tips for clinicians. You think that I’m going to be starting off by telling you about the differences in how we’re going to manage the patients, but I’m not. The reason I’m not going to do that is because our national guidelines are not sex specific.

What I’m really going to discuss with you today are the data so that you can decide for yourself what we should do and whether there really are differences. As we begin, I always think about the prevalence of the disease. Currently, there are 6.7 million Americans with heart failure, and approximately 45% of them are women. Globally, our best research shows that there are over 56 million people living with heart failure, and half of them are women.

We also know that there are different underlying causes in women and men. For women, the four risk factors are hypertension, diabetes, atrial fibrillation (AFib), and left bundle branch block. I know you knew about hypertension. Diabetes may not have been right up there in your mind. You see many women with AFib, so I know that you were thinking about it. We’re going to come back to left bundle branch block; it really is very interesting.

For men, it is the risk for heart failure development after a myocardial infarction. Men are more likely to have an ischemic cardiomyopathy. It is also important to state that when women have heart failure, it is often with more preserved ejection fraction. We know that heart failure with preserved ejection fraction (HFpEF) is more common in women and heart failure with reduced ejection fraction (HFrEF) is more common in men.

Now we’re going to talk about the four pillars in medical management, and we’re going to start out with the easy medications that show no sex differences in benefit. The mineralocorticoid receptor antagonists (MRAs) show that there are no sex differences in regard to benefit. Women benefit as much as men, based on two of the largest studies, which were the RALES study, which studied heart failure that was ischemic and nonischemic, and then the EPHESUS study, which was specific to patients who had myocardial infarction. There was a mortality benefit in the women.

The next set of drugs that we’re going to mention are the sodium-glucose cotransporter 2 (SGLT2) inhibitors. The combined endpoint for women and men was a combined endpoint of death and heart failure hospitalization. No matter what the ejection fraction was, women benefited like men for this drug.

The third class of agents that I want to discuss is the beta-blockers, which are really very interesting because they’re so powerful. The studies for these drugs were stopped prematurely. When you take into consideration that women are underenrolled in clinical trials, remember that the studies for these drugs were stopped, so there weren’t that many women. The fact that we showed a mortality benefit is really important.

The first drug that we’re going to refer to is bisoprolol because CIBIS II was the first trial for this drug to demonstrate a mortality benefit in women and men. The second drug that I want to mention is metoprolol XL, which did not demonstrate a mortality benefit in the MERIT-HF study, but did demonstrate a benefit in reduced heart failure hospitalizations, which is also very important.

The third drug is carvedilol, which had been shown to reduce a combined endpoint of mortality and heart failure hospitalizations for patients with moderate symptoms. When I talk about these studies, they have anywhere from 250 to 1000 women enrolled, so these are relatively small studies and they still did demonstrate a benefit.

When we talk about angiotensin receptor–neprilysin inhibitors (ARNI), I think that’s when it gets a little complex. The data are not very clear because ARNI is a combination pill — sacubitril combined with valsartan. When you have an ideal control for a study and you want to know what your magic ingredient is, which is the sacubitril, you really want to compare valsartan with ARNI so that you can find out what your magic little ingredient is doing.

When we had the PARAGON-HF study, which was for HFpEF patients who had an ejection fraction greater than 45%, there was a benefit in the women and not in the men, and that really was in the women with the lower ejection fractions. That’s very interesting because the control was valsartan.

When we had the PARADIGM-HF study, that was more complex. The control was an angiotensin-converting enzyme (ACE) inhibitor, which is not an ideal control for women since, even in a meta-analysis that had over 1000 women, there has not been a proven benefit. The confidence intervals remain wide. Therefore, it’s not quite a fair comparison to randomize women to ARNI versus an ACE inhibitor. Comparing ARNI to valsartan would be better in order to determine the additional benefit of sacubitril since valsartan alone has already been shown, in the Val-HeFT study, to reduce heart failure hospitalizations in women — although not mortality. There was a benefit.

When you look at the PARADIGM-HF study, which was for HFrEF patients, and you see that there is a benefit in the women, where the combined endpoint was heart failure hospitalization and mortality, you then see that there’s a figure that shows what happens when we look at mortality alone. The benefit is not driven by mortality; it’s driven by heart failure hospitalizations for the women, for which valsartan already had been shown to do this. Therefore, I don’t know if sacubitril/valsartan is more powerful because we didn’t have the right control in studies. From my standpoint, the data really are not there. We can all have our own biased opinions.

When we talk about devices, that gets really interesting because it goes back to those risk factors. We’re going to start with implantable cardioverter defibrillators (ICDs).

BOSTON — A Mediterranean diet with extra virgin olive oil (EVOO) significantly reduced the risk for tachyarrhythmia recurrence after atrial fibrillation (AF) ablation in patients with paroxysmal disease, but the diet had less of an impact on patients with persistent AF, a new study showed.

“An intervention with the Mediterranean diet with EVOO produced a nonsignificant reduction in any atrial tachycardia in a selected population after undergoing atrial fibrillation ablation, but this intervention produced a significant reduction in any atrial tachyarrhythmias in patients with paroxysmal AF,” said Maria Teresa Barrio-Lopez, MD, PhD, an electrophysiologist at University Hospital HM Monteprincipe in Madrid, Spain, who presented results from the PREDIMAR trial at the Heart Rhythm Society (HRS) 2024 annual meeting.

The PREDIMAR study enrolled 720 patients from the larger PREDIMED study, which showed that patients without AF at enrollment and who followed a Mediterranean diet enriched with EVOO had a 38% lower rate of incidental AF than control individuals.

PREDIMAR evaluated the impact of the diet on arrhythmia recurrence in patients after ablation. The patients were randomized in a 1:1 ratio to either the dietary intervention group or the control group.
 

PREDIMAR Study Results

The overall difference in the rate of AF recurrence in the 3-18 months after ablation between the dietary intervention and control groups was nonsignificant (34.8% vs 37.5%).

However, among the 431 patients with paroxysmal AF, 25.2% in the diet group and 34.7% in the control group had no tachyarrhythmia recurrence, which translates into a 31% lower risk in the diet group.

In this study, the diet was rich in fish, nuts, fruits, and vegetables and was complemented with EVOO. Participants were also permitted moderate wine consumption.

The intervention involved dietitians who remotely followed patients and made periodic telephone calls to encourage them to stay on the diet. Participants had weight and body measurements taken at baseline and at 3, 6, 12, and 18 months and underwent an ECG at 6, 12, and 18 months. Labs were obtained at baseline and at 12 months. Participants were also given educational materials throughout the intervention.

Average scores, based on a scale of 0-13, excluding an item for wine intake, were 7.8 in the diet group and 7.2 in the control group.

Daily average alcohol intake was higher in the diet group than in the control group (9.8 vs 8.2 g), but “the weight of the patient during the study didn’t change in any group,” Dr. Barrio-Lopez reported.

Baseline characteristics were similar in the two groups. About 60% were taking antiarrhythmic drugs, and about 84% were taking anticoagulants.
 

‘A Tour de Force’

PREDIMAR was “really a tour de force,” Christine Albert, MD, MPH, chair of cardiology at the Smidt Heart Institute at the Cedars-Sinai Medical Center in Los Angeles, California, said during a commentary presented at HRS. “We talk about how we’re going to do these dietary interventions and weight loss and all the risk-factor reduction, and they pulled it off with 700 individuals and also did it in a way that was very novel.”

This is the first large-scale dietary intervention trial of patients with AF. However, Dr. Albert noted later in an interview, the Mediterranean diet poses potential challenges for some people with AF.

“The Mediterranean diet recommends that people drink wine, but then there’s clear evidence that abstinence from alcohol actually reduces recurrences of atrial fibrillation, so even though there are a lot of things about the Mediterranean diet that are probably healthy and good for atrial fibrillation, that aspect of it might be working against the patient,” she explained.

The finding that patients in the Mediterranean diet group experienced no significant weight loss could be counterintuitive when it comes to preventing AF. But “you could adapt the diet for AF,” Dr. Albert said. You could “leave out the wine and focus more on weight loss if the patient is obese because those are also the pillars of what we’ve learned for patients with atrial fibrillation.”

Making weight loss a key component of the study could be significant for the American population. “At least in the United States, that’s a huge part of the risk factors for atrial fibrillation after ablation,” she said.

The remote follow-up component of the PREDIMAR study is also intriguing. “I think what’s most exciting about what they did is, they showed they can do all these things remotely,” Dr. Albert added.

Dr. Barrio-Lopez had no relevant financial relationships. Dr. Albert disclosed relationships with Abbott, Roche Diagnostics, St. Jude Medical, Boston Scientific, Medtronic, and Element Science.

WASHINGTON – Women with autoimmune liver diseases (AILD) may face increased risks for major adverse cardiovascular outcomes, according to a study presented at the annual Digestive Disease Week^® (DDW).

In particular, women with autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) appear to have higher risks than women without AIH or PBC. Those with primary sclerosing cholangitis (PSC) don’t seem to have increased risks.

“We know that cardiovascular disease remains the number one cause of death, but the mortality rate for women over the last decade has plateaued, whereas in men it’s actually declining due to interventions,” said lead author Rachel Redfield, MD, a transplant hepatology fellow at Thomas Jefferson University Hospital in Philadelphia.

“This is likely because we don’t have adequate risk stratification, especially for women,” she said. “We know that immune-mediated diseases — such as rheumatoid arthritis and psoriasis — carry a higher risk of cardiovascular disease, but there’s not a lot of data on our autoimmune liver disease patients.”

Dr. Redfield

Although being a female can offer protection against some CVD risks, the atherosclerotic cardiovascular disease (ASCVD) 10-year risk score calculator recommended by the American College of Cardiology doesn’t include chronic inflammatory diseases associated with increased CVD risk, including AILD.

Dr. Redfield and colleagues conducted a multicenter, retrospective cohort study of patients with AIH, PBC, and PSC from 1999-2019. Using TriNetX data, the researchers looked at women with AILD who also had diabetes mellitus, hypertension, and hyperlipidemia, as well as a control group of men and women with these same disorders, excluding those who used biologics, immune modulators, and steroids or had other autoimmune disorders.

The research team used 1:1 propensity-score matching for women in the study group and in the control group based on age, race, ethnicity, ASCVD risk factors, and tobacco use. Women in the study group and men in the control group were matched for age, race, ethnicity, and tobacco use.

The primary outcome was summative cardiovascular risk, including unstable angina, acute myocardial infarction, presence of coronary angioplasty implant, coronary artery bypass, percutaneous coronary intervention, and cerebral infarction.

Overall, women with AIH had a significantly higher cardiovascular risk compared to women without AIH, at 25.4% versus 20.6% (P = .0007).

Specifically, women with PBC had a significantly higher cardiovascular risk compared to women without PBC, at 27.05% versus 20.9% (P < .0001).

There wasn’t a significant difference in risk between women with and without PSC, at 27.5% versus 21.8% (P = .27).

When compared to men without disease, women with AIH didn’t have a statistically significant higher risk, at 25.3% versus 24.2% (P = .44). Similarly, there didn’t appear to be a significant difference between women with PBC and men without PBC, at 26.9% versus 25.9% (P = .52), or between women with PSC and men without PSC, at 27.7% versus 26.2% (P = .78).

Dr. Redfield and colleagues then compared the ASCVD-calculated risk versus database risk, finding that in each group of women with AILD — including AIH, PBC, and PSC — the ASCVD-calculated risk was around 11%, compared with database risk scores of 25% for AIH, 27% for PBC, and 28% for PSC. These database risks appeared similar to both the ASCVD and database risk percentages for men.

“So potentially there’s an oversight in women with any kind of inflammatory disease, but specifically here, autoimmune liver diseases,” she said. “We really need to enhance our risk assessment strategies to take into account their risk and optimize patient outcomes.”

Dr. Redfield noted the limitations with using TriNetX data, including coding consistency among providers and healthcare organizations, unknown patient follow-up dates, and the inability to capture various inflammatory disease phenotypes, such as autoimmune hepatitis with multiple flares, which may be associated with higher cardiovascular risks.

As an attendee of the DDW session, Kenneth Kelson, MD, a gastroenterologist with Fremont Medical Group and Washington Hospital Healthcare System in Fremont, California, noted the importance of investigating the effects of different types of statins in these patients. Although the research team looked at top-level differences among statin users, finding that women with AILD were more likely to be on a statin, they didn’t incorporate statin therapy in the propensity-score matching model.

“Lipid-soluble statins are known to cause more liver trouble, even though it’s pretty low,” Dr. Kelson said. “Whereas the water-soluble statins have a lower incidence of liver issues.”

Dr. Redfield and Dr. Kelson reported no relevant disclosures.

Dr. Redfield and colleagues conducted a multicenter, retrospective cohort study of patients with AIH, PBC, and PSC from 1999-2019. Using TriNetX data, the researchers looked at women with AILD who also had diabetes mellitus, hypertension, and hyperlipidemia, as well as a control group of men and women with these same disorders, excluding those who used biologics, immune modulators, and steroids or had other autoimmune disorders.

The research team used 1:1 propensity-score matching for women in the study group and in the control group based on age, race, ethnicity, ASCVD risk factors, and tobacco use. Women in the study group and men in the control group were matched for age, race, ethnicity, and tobacco use.

The primary outcome was summative cardiovascular risk, including unstable angina, acute myocardial infarction, presence of coronary angioplasty implant, coronary artery bypass, percutaneous coronary intervention, and cerebral infarction.

Overall, women with AIH had a significantly higher cardiovascular risk compared to women without AIH, at 25.4% versus 20.6% (P = .0007).

Specifically, women with PBC had a significantly higher cardiovascular risk compared to women without PBC, at 27.05% versus 20.9% (P < .0001).

There wasn’t a significant difference in risk between women with and without PSC, at 27.5% versus 21.8% (P = .27).

When compared to men without disease, women with AIH didn’t have a statistically significant higher risk, at 25.3% versus 24.2% (P = .44). Similarly, there didn’t appear to be a significant difference between women with PBC and men without PBC, at 26.9% versus 25.9% (P = .52), or between women with PSC and men without PSC, at 27.7% versus 26.2% (P = .78).

Dr. Redfield and colleagues then compared the ASCVD-calculated risk versus database risk, finding that in each group of women with AILD — including AIH, PBC, and PSC — the ASCVD-calculated risk was around 11%, compared with database risk scores of 25% for AIH, 27% for PBC, and 28% for PSC. These database risks appeared similar to both the ASCVD and database risk percentages for men.

“So potentially there’s an oversight in women with any kind of inflammatory disease, but specifically here, autoimmune liver diseases,” she said. “We really need to enhance our risk assessment strategies to take into account their risk and optimize patient outcomes.”

Dr. Redfield noted the limitations with using TriNetX data, including coding consistency among providers and healthcare organizations, unknown patient follow-up dates, and the inability to capture various inflammatory disease phenotypes, such as autoimmune hepatitis with multiple flares, which may be associated with higher cardiovascular risks.

As an attendee of the DDW session, Kenneth Kelson, MD, a gastroenterologist with Fremont Medical Group and Washington Hospital Healthcare System in Fremont, California, noted the importance of investigating the effects of different types of statins in these patients. Although the research team looked at top-level differences among statin users, finding that women with AILD were more likely to be on a statin, they didn’t incorporate statin therapy in the propensity-score matching model.

“Lipid-soluble statins are known to cause more liver trouble, even though it’s pretty low,” Dr. Kelson said. “Whereas the water-soluble statins have a lower incidence of liver issues.”

Dr. Redfield and Dr. Kelson reported no relevant disclosures.

WASHINGTON – Women with autoimmune liver diseases (AILD) may face increased risks for major adverse cardiovascular outcomes, according to a study presented at the annual Digestive Disease Week^® (DDW).

In particular, women with autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) appear to have higher risks than women without AIH or PBC. Those with primary sclerosing cholangitis (PSC) don’t seem to have increased risks.

“We know that cardiovascular disease remains the number one cause of death, but the mortality rate for women over the last decade has plateaued, whereas in men it’s actually declining due to interventions,” said lead author Rachel Redfield, MD, a transplant hepatology fellow at Thomas Jefferson University Hospital in Philadelphia.

“This is likely because we don’t have adequate risk stratification, especially for women,” she said. “We know that immune-mediated diseases — such as rheumatoid arthritis and psoriasis — carry a higher risk of cardiovascular disease, but there’s not a lot of data on our autoimmune liver disease patients.”

BOSTON — Patients who have had a stroke are thought to be at a higher risk for another one, but oral anticoagulation with edoxaban led to no discernible reduction in the risk for a second stroke, and the risk for major bleeding was more than quadruple the risk with no anticoagulation, a subanalysis of a major European trial has shown.

“There is no interaction between prior stroke or TIA [transient ischemic attack] and the treatment effect, and this is true for the primary outcome and the safety outcome,” Paulus Kirchoff, MD, director of cardiology at the University Heart and Vascular Center in Hamburg, Germany, said during his presentation of a subanalysis of the NOAH-AFNET 6 trial at the annual meeting of the Heart Rhythm Society (HRS) 2024. However, “there is a signal for more safety events in patients randomized to anticoagulation with a prior stroke.”

The subanalysis involved 253 patients who had had a stroke or TIA and who had device-detected atrial fibrillation (AF) from the overall NOAH-AFNET 6 population of 2536 patients, which enrolled patients 65 years and older with at least one additional CHA2DS-VASc risk factor and patients 75 years and older with device-detected subclinical AF episodes of at least 6 minutes. Patients were randomized to either edoxaban or no anticoagulation, but 53.9% of the no-anticoagulation group was taking aspirin at trial enrollment. Anticoagulation with edoxaban was shown to have no significant impact on stroke rates or other cardiovascular outcomes.
 

Subanalysis Results

In the subanalysis, a composite of stroke, systemic embolism, and cardiovascular death — the primary outcome — was similar in the edoxaban and no-anticoagulation groups (14/122 patients [11.5%] vs 16/131 patients [12.2%]; 5.7% vs 6.3% per patient-year).

The rate of recurrent stroke was also similar in the edoxaban and no-anticoagulation groups (4 of 122 patients [3.3%] vs 6 of 131 patients [4.6%]; 1.6% vs 2.3% per patient-year). And there were eight cardiovascular deaths in each group.

However, edoxaban patients had significantly higher rates of major bleeding.

“This is a subanalysis, so what we see in terms of the number of patients with events is not powered for a definitive answer, but we do see that there were 10 major bleeds in the group of patients with a prior stroke or TIA in NOAH,” Dr. Kirchoff reported. “Eight of those 10 major bleeds occurred in patients randomized to edoxaban.”

Results from the NOAH-AFNET 6 trial have been compared with those from the ARTESiA trial, which compared apixaban anticoagulation with aspirin in patients with subclinical AF and was also presented at HRS 2024. ARTESiA showed that apixaban significantly lowered the risk for stroke and systemic embolism.

“In ARTESiA, everyone was on aspirin when they were randomized to no anticoagulation; in NOAH, only about half were on aspirin,” Dr. Kirchoff said.

Both studies had similar outcomes for cardiovascular death in the anticoagulation and no-anticoagulation groups. “It’s not significant; it may be chance, but it’s definitely not the reduction in death that we have seen in the anticoagulant trials,” Dr. Kirchoff said. “When you look at the meta-analyses of the early anticoagulation trials, there’s a one third reduction in death, and here we’re talking about a smaller reduction.”

This research points to a need for a better way to evaluate stroke risk. “We need new markers,” Dr. Kirchoff said. “Some of them may be in the blood or imaging, genetics maybe, and one thing that really emerges from my perspective is that we now have the first evidence to suggest that patients with a very low atrial fibrillation burden have a low stroke rate.”

More research is needed to better understand AF characteristics and stroke risk, he said.
 

AF Care Enters a ‘Gray Zone’

The NOAH-AFNET 6 results, coupled with those from ARTESiA, are changing the paradigm for anticoagulation in patients with stroke, said Taya Glotzer, MD, an electrophysiologist at the Hackensack University Medical Center in Hackensack, New Jersey, who compiled her own analysis of the studies’ outcomes.

“In ARTESiA, the stroke reduction was only 0.44% a year, with a number needed to treat of 250,” she said. “In the NOAH-AFNET 6 main trial, the stroke reduction was 0.2%, with the number needed to treat of 500, and in the NOAH prior stroke patients, there was a 0.7% reduction, with a number needed to treat of 143.”

None of these trials would meet the standard for a class 1 recommendation for anticoagulation with a reduction of even 1%-2% per year, she noted, but they do show that the stroke rate “is very, very low” in prior patients with stroke.

“Prior to 2024, we knew what was black and white; we knew who to anticoagulate and who not to anticoagulate. And now we are in a gray zone, trying to balance the risk of stroke and bleeding. We have to individualize or hope for substudies, perhaps using the CHA2DS-VASc score or other information about the left atrium, to help us make decisions in these patients. It’s not just going to be black and white,” she said.

Dr. Kirchoff had no relevant financial relationships to disclose. Dr. Glotzer disclosed financial relationships with Medtronic, Abbott, Boston Scientific, and MediaSphere Medical.

LISBON, PORTUGAL — Few people with suspected heart failure and elevated N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels are receiving a diagnosis after a year, reported investigators, who say high rates of hospitalization are common.

Presenting here at the Heart Failure Association of the European Society of Cardiology (HFA-ESC) 2024, researchers shared results from the REVOLUTION-HF study involving almost 8000 people who consulted outpatient primary and secondary care over a 5-year period.

About two thirds of the patients had suspected heart failure; however, less than 30% of the people received a diagnosis within a year.

Yet hospitalization was eight times higher in the suspected heart failure group than in the control group, and all-cause mortality was nearly doubled. The outcomes were even worse in patients with high NT-proBNP levels.

Patients with suspected heart failure are “waiting far too long to see a specialist, and that results in a delay to guideline-directed medical therapy, despite the fact that we’re perfectly happy to slap them all on diuretics,” said study presenter Lisa Anderson, MD, PhD, Cardiovascular Clinical Academic Group, Molecular and Clinical Sciences Research Institute, St George’s Hospital, University of London, England.

“We need to rethink our management of heart failure patients presenting in the community,” she said.

A big gap exists internationally between presentation with heart failure, an elevated NT-proBNP, and confirmatory specialist assessment, she explained.

“It’s a scandal that patients are coming to the GP with signs and symptoms of heart failure, they get tested for natriuretic peptides, and nothing happens,” said co-author Antoni Bayés-Genís, MD, PhD, Heart Institute director, Hospital Universitari Germans Trias i Pujol Catedràtic, Barcelona, Spain.

“These patients may receive an echo, or not, in the coming 12 months,” and “during these 12 months, there is a huge number of heart failure hospitalizations and deaths that could probably be prevented.”
 

Why the Reluctance to Diagnose?

Many issues get in the way of early diagnosis, Dr. Bayés-Genís said. “Inertia, comorbidities, ageism.”

A lot of patients with heart failure are elderly women with some degree of weight gain, he said. “And they come to the clinic with fatigue, so we tell them, ‘Well, that’s normal.”

But “it may not be normal,” he added. “This is a very important topic that we, as a society, need to address.”

There are several “misconceptions” about heart failure, said Ileana L. Piña, MD, MPH, the Robert Stein Chair for Quality and Safety, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, who was not involved in the study.

For example, “we’re all convinced that guideline-directed medical therapy works,” but the evidence is only for patients “with a diagnosis.” In addition, “millions of patients get tested” for heart failure, but they already have a “known diagnosis.”

“When we study these drugs, we’re studying them on patients with manifest disease,” who are only then randomized, Dr. Piña said. “But we seldom see them while they’re developing heart failure. And it’s a process; it doesn’t happen overnight.”

Patients initially often think they may have asthma, and so what follows is an extended period of “uncertainty” and “important time lost” before they finally undergo the assessments that show that they have heart failure, she said.

However, “uncertainty” often lands a patient “in the emergency room or with an unscheduled office visit, where NT-proBNP might get ordered and there’s a long lineup for an echo.”

There are several strengths of the current study, Dr. Piña said, including the fact that 50% of the study population were women, and they were older than a typical trial population. Nevertheless, the results were “eye-opening but not surprising” and, in the end, “disappointing.”

“I agree, we need a revolution, Dr. Anderson,” Dr. Piña said. “The revolution of paying attention to the NT-proBNP when you get it and it’s elevated” and then following through with echocardiography and starting “guideline-directed medical therapy early.”

The diagnosis of heart failure “relies on the presentation of patients with nonspecific signs and symptoms,” such as dyspnea and peripheral edema, “but initiation of guideline-directed medical therapy — life-saving treatment — has to wait until we have a formal echocardiography and specialist clinician assessment,” Dr. Anderson said.

The latest clinical consensus statement from the Heart Failure Association “proposes both rule-in and rule-out NT-proBNP levels for heart failure diagnosis, and obviously we all recognize that it’s important to treat patients as soon as they’re diagnosed,” she explained.
 

REVOLUTION-HF

To examine the risk profile for patients presenting to outpatient care with suspected heart failure, the researchers conducted REVOLUTION-HF, which leveraged nationwide Swedish linked data from general practices, specialists, pharmacies, hospitals, and cause of death registers.

“Really impressively, most of these NT-proBNP tests were coming back within a day,” Dr. Anderson said, “so a really, really good turnaround.”

Individuals were excluded if they had an inpatient admission, echocardiography, or heart failure diagnosis between presentation and the NT-proBNP measurement.

These people were then compared with those presenting to primary or secondary outpatient care for any reason and matched for age, sex, care level, and index year. Both groups were followed up for 1 year.

“Despite this really impressive, almost immediate NT-proBNP testing,” the waiting times to undergo echocardiography were “really disappointing,” Dr. Anderson said.

The median time to first registered echocardiography was 40 days, and only 29% of patients with suspected heart failure received a diagnosis within a year of the index presentation date, which she described as “inadequately slow.”

“And how does this translate to medical therapy?” she asked.
 

Heart Failure Drugs

After the index presentation, the rate of loop diuretic use quadrupled among individuals suspected of having heart failure, but there was a “muted response” when it came to the prescribing of beta-blockers and the other pillars of heart failure therapy, which Dr. Anderson called “very disappointing.”

For outcomes after the index presentation, the rate of hospitalization was much higher in the group with suspected heart failure than in the control group (16.1 vs 2.2 events per 100 person-years). And all-cause mortality occurred more often in the group with suspected heart failure than in the control group (10.3 vs 6.5 events per 100 person-years).

Among patients with NT-proBNP levels of 2000 ng/L, there was a “rapid” onset of hospitalization “within the first few days” of the index presentation, which was tracked by a more linear rise in all-cause deaths, Dr. Anderson reported.

In the United Kingdom, “we are very proud of our 2- and 6-week pathways,” which stipulate that suspected heart failure patients with NT-proBNP levels between 400 and 2000 ng/L are to have a specialist assessment and transthoracic echocardiography within 6 weeks; for those with levels > 2000 ng/L, that interval is accelerated to 2 weeks, she said.

The current results show that “2 weeks is too slow.” And looking at the rest of the cohort with lower NT-proBNP levels, “patients have already been admitted and died” by 6 weeks, she said.

When patients are stratified by age, “you get exactly what you would expect,” Dr. Anderson said. “The older patients are the most at risk” for both hospitalization and all-cause mortality.

Why the Reluctance to Diagnose?

Many issues get in the way of early diagnosis, Dr. Bayés-Genís said. “Inertia, comorbidities, ageism.”

A lot of patients with heart failure are elderly women with some degree of weight gain, he said. “And they come to the clinic with fatigue, so we tell them, ‘Well, that’s normal.”

But “it may not be normal,” he added. “This is a very important topic that we, as a society, need to address.”

There are several “misconceptions” about heart failure, said Ileana L. Piña, MD, MPH, the Robert Stein Chair for Quality and Safety, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, who was not involved in the study.

For example, “we’re all convinced that guideline-directed medical therapy works,” but the evidence is only for patients “with a diagnosis.” In addition, “millions of patients get tested” for heart failure, but they already have a “known diagnosis.”

“When we study these drugs, we’re studying them on patients with manifest disease,” who are only then randomized, Dr. Piña said. “But we seldom see them while they’re developing heart failure. And it’s a process; it doesn’t happen overnight.”

Patients initially often think they may have asthma, and so what follows is an extended period of “uncertainty” and “important time lost” before they finally undergo the assessments that show that they have heart failure, she said.

However, “uncertainty” often lands a patient “in the emergency room or with an unscheduled office visit, where NT-proBNP might get ordered and there’s a long lineup for an echo.”

There are several strengths of the current study, Dr. Piña said, including the fact that 50% of the study population were women, and they were older than a typical trial population. Nevertheless, the results were “eye-opening but not surprising” and, in the end, “disappointing.”

“I agree, we need a revolution, Dr. Anderson,” Dr. Piña said. “The revolution of paying attention to the NT-proBNP when you get it and it’s elevated” and then following through with echocardiography and starting “guideline-directed medical therapy early.”

The diagnosis of heart failure “relies on the presentation of patients with nonspecific signs and symptoms,” such as dyspnea and peripheral edema, “but initiation of guideline-directed medical therapy — life-saving treatment — has to wait until we have a formal echocardiography and specialist clinician assessment,” Dr. Anderson said.

The latest clinical consensus statement from the Heart Failure Association “proposes both rule-in and rule-out NT-proBNP levels for heart failure diagnosis, and obviously we all recognize that it’s important to treat patients as soon as they’re diagnosed,” she explained.
 

REVOLUTION-HF

To examine the risk profile for patients presenting to outpatient care with suspected heart failure, the researchers conducted REVOLUTION-HF, which leveraged nationwide Swedish linked data from general practices, specialists, pharmacies, hospitals, and cause of death registers.

“Really impressively, most of these NT-proBNP tests were coming back within a day,” Dr. Anderson said, “so a really, really good turnaround.”

Individuals were excluded if they had an inpatient admission, echocardiography, or heart failure diagnosis between presentation and the NT-proBNP measurement.

These people were then compared with those presenting to primary or secondary outpatient care for any reason and matched for age, sex, care level, and index year. Both groups were followed up for 1 year.

“Despite this really impressive, almost immediate NT-proBNP testing,” the waiting times to undergo echocardiography were “really disappointing,” Dr. Anderson said.

The median time to first registered echocardiography was 40 days, and only 29% of patients with suspected heart failure received a diagnosis within a year of the index presentation date, which she described as “inadequately slow.”

“And how does this translate to medical therapy?” she asked.
 

Heart Failure Drugs

After the index presentation, the rate of loop diuretic use quadrupled among individuals suspected of having heart failure, but there was a “muted response” when it came to the prescribing of beta-blockers and the other pillars of heart failure therapy, which Dr. Anderson called “very disappointing.”

For outcomes after the index presentation, the rate of hospitalization was much higher in the group with suspected heart failure than in the control group (16.1 vs 2.2 events per 100 person-years). And all-cause mortality occurred more often in the group with suspected heart failure than in the control group (10.3 vs 6.5 events per 100 person-years).

Among patients with NT-proBNP levels of 2000 ng/L, there was a “rapid” onset of hospitalization “within the first few days” of the index presentation, which was tracked by a more linear rise in all-cause deaths, Dr. Anderson reported.

In the United Kingdom, “we are very proud of our 2- and 6-week pathways,” which stipulate that suspected heart failure patients with NT-proBNP levels between 400 and 2000 ng/L are to have a specialist assessment and transthoracic echocardiography within 6 weeks; for those with levels > 2000 ng/L, that interval is accelerated to 2 weeks, she said.

The current results show that “2 weeks is too slow.” And looking at the rest of the cohort with lower NT-proBNP levels, “patients have already been admitted and died” by 6 weeks, she said.

When patients are stratified by age, “you get exactly what you would expect,” Dr. Anderson said. “The older patients are the most at risk” for both hospitalization and all-cause mortality.

LISBON, PORTUGAL — Few people with suspected heart failure and elevated N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels are receiving a diagnosis after a year, reported investigators, who say high rates of hospitalization are common.

Presenting here at the Heart Failure Association of the European Society of Cardiology (HFA-ESC) 2024, researchers shared results from the REVOLUTION-HF study involving almost 8000 people who consulted outpatient primary and secondary care over a 5-year period.

About two thirds of the patients had suspected heart failure; however, less than 30% of the people received a diagnosis within a year.

Yet hospitalization was eight times higher in the suspected heart failure group than in the control group, and all-cause mortality was nearly doubled. The outcomes were even worse in patients with high NT-proBNP levels.

Patients with suspected heart failure are “waiting far too long to see a specialist, and that results in a delay to guideline-directed medical therapy, despite the fact that we’re perfectly happy to slap them all on diuretics,” said study presenter Lisa Anderson, MD, PhD, Cardiovascular Clinical Academic Group, Molecular and Clinical Sciences Research Institute, St George’s Hospital, University of London, England.

“We need to rethink our management of heart failure patients presenting in the community,” she said.

A big gap exists internationally between presentation with heart failure, an elevated NT-proBNP, and confirmatory specialist assessment, she explained.

“It’s a scandal that patients are coming to the GP with signs and symptoms of heart failure, they get tested for natriuretic peptides, and nothing happens,” said co-author Antoni Bayés-Genís, MD, PhD, Heart Institute director, Hospital Universitari Germans Trias i Pujol Catedràtic, Barcelona, Spain.

Among stroke survivors with diabetes or obesity, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) reduced secondary stroke risk by up to 16%, according to authors of a recent meta-analysis. With benefits across administration routes, dosing regimens, type 2 diabetes status, and total and nonfatal strokes, the findings could improve GLP-1 RA implementation by stroke specialists in patients with stroke history and concurrent type 2 diabetes or obesity, authors said. The study was published online in the International Journal of Stoke.

Extending Longevity

Agents including GLP-1 RAs that have been found to reduce cardiovascular events among patients with type 2 diabetes and patients who are overweight or obese also reduce risk of recurrent stroke among patients with a history of stroke who are overweight, obese, or have metabolic disease, said American Heart Association (AHA) Chief Clinical Science Officer Mitchell S. V. Elkind, MD, who was not involved with the study but was asked to comment.

“Stroke is a leading cause of mortality and the leading cause of serious long-term disability,” he added, “so medications that help to reduce that risk can play an important role in improving overall health and well-being and hopefully reducing premature mortality.”

Investigators Anastasia Adamou, MD, an internal medicine resident at AHEPA University Hospital in Thessaloniki, Greece, and colleagues searched MEDLINE and Scopus for cardiovascular outcome trials involving adults randomly assigned to GLP-1 RAs or placebo through November 2023, ultimately analyzing 11 randomized controlled trials (RCTs).

Among 60,380 participants in the nine studies that assessed total strokes, 2.5% of the GLP-1 RA group experienced strokes during follow-up, versus 3% in the placebo group (relative risk [RR] 0.85, 95% confidence interval [CI] 0.77-0.93). Regarding secondary outcomes, the GLP-1 RA group showed a significantly lower rate of nonfatal strokes versus patients on placebo (RR 0.87, 95% CI 0.79-0.95). Conversely, investigators observed no significant risk difference among the groups regarding fatal strokes, probably due to the low rate of events — 0.3% and 0.4% for treated and untreated patients, respectively.

Subgroup analyses revealed no interaction between dosing frequency and total, nonfatal, or fatal strokes. The investigators observed no difference in nonfatal strokes among participants by type 2 diabetes status and medication administration route (oral versus subcutaneous).

“The oral administration route could provide the advantage of lower local ecchymoses and allergic reactions due to subcutaneous infusions,” Dr. Adamou said in an interview. But because oral administration demands daily intake, she added, treatment adherence might be affected. “For this reason, our team performed another subgroup analysis to compare the once-a-day to the once-a-month administration. No interaction effect was again presented between the two subgroups. This outcome allows for personalization of the administration method for each patient.”

Addressing Underutilization

Despite more than 2 decades of widespread use and well-established effects on body weight, HbA1c, and cardiovascular risk, GLP-1 RAs remain underutilized, authors wrote. This is especially true in primary care, noted one study published in Clinical Diabetes.

“GLP-1 RAs have been used for many years to treat diabetic patients,” said Dr. Adamou. But because their impact on cardiovascular health regardless of diabetic status is only recently known, she said, physicians are exercising caution when prescribing this medication to patients without diabetes. “This is why more studies need to be available, especially RCTs.”

Most neurologists traditionally have left management of type 2 diabetes and other metabolic disorders to primary care doctors, said Dr. Elkind. “However, these medications are increasingly important to vascular risk reduction and should be considered part of the stroke specialist’s armamentarium.”

Vascular neurologists can play an important role in managing metabolic disease and obesity by recommending GLP-1 RAs for patients with a history of stroke, or by initiating these medications themselves, Dr. Elkind said. “These drugs are likely to become an important part of stroke patients’ medication regimens, along with antithrombotic agents, blood pressure control, and statins. Neurologists are well-positioned to educate other physicians about the important connections among brain, heart, and metabolic health.”

To that end, he said, the AHA will update guidelines for both primary and secondary stroke prevention as warranted by evidence supporting GLP-1 RAs and other medications that could impact stroke risk in type 2 diabetes and related metabolic disorders. However, no guidelines concerning use of GLP-1 RAs for secondary stroke prevention in obesity exist. Here, said Dr. Elkind, the AHA will continue building on its innovative Cardiovascular-Kidney Metabolic Health program, which includes clinical suggestions and may include more formal clinical practice guidelines as the evidence evolves.

Among the main drivers of the initiative, he said, is the recognition that cardiovascular disease — including stroke — is the major cause of death and morbidity among patients with obesity, type 2 diabetes, and metabolic disorders. “Stroke should be considered an important part of overall cardiovascular risk, and the findings that these drugs can help to reduce the risk of stroke specifically is an important additional reason for their use.”

Dr. Elkind and Dr. Adamou reported no conflicting interests. The authors received no financial support for the study.

LISBON, PORTUGAL — The addition of a yearlong customized yoga therapy intervention to guideline-directed medical therapy (GDMT) appears to significantly improve heart failure measures associated with long-term prognosis, findings from an Indian study suggested.

The research, presented at the Heart Failure Association of the European Society of Cardiology (HFA-ESC) 2024 congress, involved 105 patients assigned to yoga plus GDMT or GDMT alone and demonstrated that there was a large shift in the New York Heart Association (NYHA) functional class from baseline to the 52-week follow-up.

“Yoga therapy has a beneficial impact on heart failure patients on optimal medical management,” said study presenter Ajit Singh, MD, Department of Medicine, Kasturba Medical College, Manipal, Karnataka, India, and the study “demonstrated an overall improvement in left ventricle dimensions and function.”

However, because patients were followed every day and almost a quarter had dropped out by 6 months, the study was “a challenge,” he noted. Nevertheless, the addition of yoga to GDMT could be a “game changer if we try for longer duration.”

For yoga therapy to be considered in clinical practice, a randomized study is required, said session cochair Dana Dawson, MD, PhD, professor of cardiovascular medicine and lead of the Cardiology and Cardiovascular Research Unit, University of Aberdeen, Scotland.

Patients in the current analysis, however, were not randomly allocated to treatment group, which resulted in baseline discrepancies that made the groups “incomparable,” Dr. Dawson explained.

Still, the study showed that yoga is feasible in this patient group and that, even just comparing baseline and follow-up outcomes in the yoga group, there were some significant results.

“It is effective in implementing a change,” she said, “and whether that change is clinically effective needs to be tested in a clinic in a randomized study.”
 

Why Yoga May Be Particularly Effective

Yoga may be different from other exercise and lifestyle interventions because it is “also about meditation and meeting with your own self,” which corresponds to a form of cognitive behavioral therapy, albeit “conducted in singular manner,” she added.

“It’s not going to be everyone’s cup of tea, and not everyone is going to be inclined to do it,” but it could be suitable in countries where yoga is more commonly practiced as a behavioral, as opposed to lifestyle, intervention, said Dr. Dawson.

Heart failure is a “complex chronic disease” that is a “prime cause of concern for healthcare sectors worldwide,” not least in India, where there is a “very high prevalence” of the disease, Dr. Singh noted.

Evidence from the literature indicates that yoga and other lifestyle modifications can improve the quality of life of patients with heart failure, alongside measures such as left ventricular ejection fraction (LVEF) and NYHA functional class, he said. However, the researchers did not find any study that looked at yoga therapy as an adjunct to standard-of-care treatment.
 

How Yoga Was Applied

They recruited patients aged 30-70 years with persistent heart failure symptoms, an LVEF of < 45%, and NYHA class III or lower heart failure. All participants had undergone a cardiac procedure 6-12 months previously, and all were receiving optimal GDMT.

Patients were assigned in a nonrandomized fashion to GDMT with or without a customized yoga program. Eight forms of pranayama breath work, meditation, and relaxation techniques were taught to patients in the yoga group by experienced hospital faculty.

They were supervised for 1 week and then advised to continue self-administered yoga at home once a week for 45 minutes. After each home session, an instructor followed up with each study participant to monitor progress.

All participants were assessed with echocardiography and other measures, including physical activities, to determine NYHA functional status at baseline, 6 months, and 1 year.

Of the 110 patients recruited, 25 had dropped out by 6 months. Of the remaining 85 patients included in the analysis, 40 were assigned to the yoga group. The average age was 49 years, and 70 (82%) of the participants were men. The lack of women in the study is a “major drawback,” Dr. Singh noted.

Women did not want to participate, he explained, “because they were afraid to get the follow-up,” saying, “We will not be able to follow this yoga therapy for 1 year.”

After 52 weeks, patients in the yoga group had significantly greater reductions from baseline in systolic and diastolic blood pressure, heart rate, and body mass index than those in the GDMT-alone group (P < .05 for all).

Patients in the yoga group also experienced significantly greater improvements in ejection fraction, increasing from an average of 41.5% to 44.4% over the course of the study. In contrast, ejection fraction decreased from 42.3% to 41.6% in the GDMT-alone group (P < .05).

Crucially, there was a marked improvement in the NYHA class in the yoga group.

With yoga, the proportion of patients with class I heart failure increased from 12% to 47% over the 52 weeks of the study, whereas the proportion with class II heart failure decreased from 57% to 30%, and the proportion with class III heart failure decreased from 30% to 12% (P <  .001). In both the yoga and GDMT-alone groups, the proportion of patients with class IV disease increased from 0% to about 10%.

However, because patients were followed every day and almost a quarter had dropped out by 6 months, the study was “a challenge,” he noted. Nevertheless, the addition of yoga to GDMT could be a “game changer if we try for longer duration.”

For yoga therapy to be considered in clinical practice, a randomized study is required, said session cochair Dana Dawson, MD, PhD, professor of cardiovascular medicine and lead of the Cardiology and Cardiovascular Research Unit, University of Aberdeen, Scotland.

Patients in the current analysis, however, were not randomly allocated to treatment group, which resulted in baseline discrepancies that made the groups “incomparable,” Dr. Dawson explained.

Still, the study showed that yoga is feasible in this patient group and that, even just comparing baseline and follow-up outcomes in the yoga group, there were some significant results.

“It is effective in implementing a change,” she said, “and whether that change is clinically effective needs to be tested in a clinic in a randomized study.”
 

Why Yoga May Be Particularly Effective

Yoga may be different from other exercise and lifestyle interventions because it is “also about meditation and meeting with your own self,” which corresponds to a form of cognitive behavioral therapy, albeit “conducted in singular manner,” she added.

“It’s not going to be everyone’s cup of tea, and not everyone is going to be inclined to do it,” but it could be suitable in countries where yoga is more commonly practiced as a behavioral, as opposed to lifestyle, intervention, said Dr. Dawson.

Heart failure is a “complex chronic disease” that is a “prime cause of concern for healthcare sectors worldwide,” not least in India, where there is a “very high prevalence” of the disease, Dr. Singh noted.

Evidence from the literature indicates that yoga and other lifestyle modifications can improve the quality of life of patients with heart failure, alongside measures such as left ventricular ejection fraction (LVEF) and NYHA functional class, he said. However, the researchers did not find any study that looked at yoga therapy as an adjunct to standard-of-care treatment.
 

How Yoga Was Applied

They recruited patients aged 30-70 years with persistent heart failure symptoms, an LVEF of < 45%, and NYHA class III or lower heart failure. All participants had undergone a cardiac procedure 6-12 months previously, and all were receiving optimal GDMT.

Patients were assigned in a nonrandomized fashion to GDMT with or without a customized yoga program. Eight forms of pranayama breath work, meditation, and relaxation techniques were taught to patients in the yoga group by experienced hospital faculty.

They were supervised for 1 week and then advised to continue self-administered yoga at home once a week for 45 minutes. After each home session, an instructor followed up with each study participant to monitor progress.

All participants were assessed with echocardiography and other measures, including physical activities, to determine NYHA functional status at baseline, 6 months, and 1 year.

Of the 110 patients recruited, 25 had dropped out by 6 months. Of the remaining 85 patients included in the analysis, 40 were assigned to the yoga group. The average age was 49 years, and 70 (82%) of the participants were men. The lack of women in the study is a “major drawback,” Dr. Singh noted.

Women did not want to participate, he explained, “because they were afraid to get the follow-up,” saying, “We will not be able to follow this yoga therapy for 1 year.”

After 52 weeks, patients in the yoga group had significantly greater reductions from baseline in systolic and diastolic blood pressure, heart rate, and body mass index than those in the GDMT-alone group (P < .05 for all).

Patients in the yoga group also experienced significantly greater improvements in ejection fraction, increasing from an average of 41.5% to 44.4% over the course of the study. In contrast, ejection fraction decreased from 42.3% to 41.6% in the GDMT-alone group (P < .05).

Crucially, there was a marked improvement in the NYHA class in the yoga group.

With yoga, the proportion of patients with class I heart failure increased from 12% to 47% over the 52 weeks of the study, whereas the proportion with class II heart failure decreased from 57% to 30%, and the proportion with class III heart failure decreased from 30% to 12% (P <  .001). In both the yoga and GDMT-alone groups, the proportion of patients with class IV disease increased from 0% to about 10%.

LISBON, PORTUGAL — The addition of a yearlong customized yoga therapy intervention to guideline-directed medical therapy (GDMT) appears to significantly improve heart failure measures associated with long-term prognosis, findings from an Indian study suggested.

The research, presented at the Heart Failure Association of the European Society of Cardiology (HFA-ESC) 2024 congress, involved 105 patients assigned to yoga plus GDMT or GDMT alone and demonstrated that there was a large shift in the New York Heart Association (NYHA) functional class from baseline to the 52-week follow-up.

Beta-blockers are excellent drugs. They’re cheap and effective; feature prominently in hypertension guidelines; and remain a sine qua non for coronary artery disease, myocardial infarction, and heart failure treatment. They’ve been around forever, and we know they work. Good luck finding an adult medicine patient who isn’t on one.

Beta-blockers act by slowing resting heart rate (and blunting the heart rate response to exercise. The latter is a pernicious cause of activity intolerance that often goes unchecked. Even when the adverse effects of beta-blockers are appreciated, providers are loath to alter dosing, much less stop the drug. After all, beta-blockers are an integral part of guideline-directed medical therapy (GDMT), and GDMT saves lives.

Balancing Heart Rate and Stroke Volume Effects

The pulmonologist sees beta-blockers differently. To augment cardiac output and optimize oxygen uptake (VO₂) during exercise, we need the heart rate response. In fact, the heart rate response contributes more to cardiac output than augmenting stroke volume (SV) and more to VO₂ than the increase in arteriovenous (AV) oxygen difference. An inability to increase the heart rate commensurate with physiologic work is called chronotropic incompetence (CI). That’s what beta-blockers do ─ they cause CI.

Physiology dictates that CI will cause activity intolerance. That said, it’s hard to quantify the impact from beta-blockers at the individual patient level. Data suggest the heart rate effect is profound. A study in patients without heart failure found that 22% of participants on beta-blockers had CI, and the investigators used a conservative CI definition (≤ 62% of heart rate reserve used). A recent report published in JAMA Cardiology found that stopping beta-blockers in patients with heart failure allowed for an extra 30 beats/min at max exercise.

Wasserman and Whipp’s textbook, the last word on all things exercise, presents a sample subject who undergoes two separate cardiopulmonary exercise tests (CPETs). Before the first, he’s given a placebo, and before the second, he gets an intravenous beta-blocker. He’s a 23-year-old otherwise healthy male — the perfect test case for isolating beta-blocker impact without confounding by comorbid diseases, other medications, or deconditioning. His max heart rate dropped by 30 beats/min after the beta-blocker, identical to what we saw in the JAMA Cardiology study (with the heart rate increasing by 30 beats/min following withdrawal). Case closed. Stop the beta-blockers on your patients so they can meet their exercise goals and get healthy!

Such pithy enthusiasm discounts physiology’s complexities. When blunting our patient’s heart rate response with beta-blockers, we also increase diastolic filling time, which increases SV. For the 23-year-old in Wasserman and Whipp’s physiology textbook, the beta-blocker increased O₂ pulse (the product of SV and AV difference). Presumably, this is mediated by the increased SV. There was a net reduction in VO₂ peak, but it was nominal, suggesting that the drop in heart rate was largely offset by the increase in O₂ pulse. For the patients in the JAMA Cardiology study, the entire group had a small increase in VO2 peak with beta-blocker withdrawal, but the effect differed by left ventricular function. Across different studies, the beta-blocker effect on heart rate is consistent but the change in overall exercise capacity is not. 

Patient Variability in Beta-Blocker Response

In addition to left ventricular function, there are other factors likely to drive variability at the patient level. We’ve treated the response to beta-blockers as a class effect — an obvious oversimplification. The impact on exercise and the heart will vary by dose and drug (eg, atenolol vs metoprolol vs carvedilol, and so on). Beta-blockers can also affect the lungs, and we’re still debating how cautious to be in the presence of asthma or chronic obstructive pulmonary disease. 

In a world of infinite time, resources, and expertise, we’d CPET everyone before and after beta-blocker use. Our current reality requires the unthinkable: We’ll have to talk to each other and our patients. For example, heart failure guidelines recommend titrating drugs to match the dose from trials that proved efficacy. These doses are quite high. Simple discussion with the cardiologist and the patient may allow for an adjustment back down with careful monitoring and close attention to activity tolerance. With any luck, you’ll preserve the benefits from GDMT while optimizing your patient›s ability to meet their exercise goals.

Women who had overweight or obesity as teens or young adults had more than a twofold increased risk for stroke before age 55, new research suggested.

An analysis of more than five decades of health data on 10,000 adults revealed that close to 5% experienced a stroke during the follow-up period, with the risk for ischemic stroke being more than twice as high in women who had obesity as teens or young adults. The risk was even higher for hemorrhagic stroke in both men and women with a history of obesity in youth.

“Our findings suggest that being overweight may have long-term health effects, even if the excess weight is temporary,” lead author Ursula Mikkola, BM, an investigator in the Research Unit of Population Health at the University of Oulu, Oulu, Finland, said in a news release.

Gender Differences

Childhood obesity has been associated with a heightened risk for cerebrovascular disease later in life, but most studies have focused on body mass index (BMI) at a single time point without considering its fluctuations throughout life, the investigators noted.

For the study, investigators used data from the Northern Finland Birth Cohort 1966, a prospective, general population-based birth cohort that followed 10,491 individuals (5185 women) until 2020 or the first stroke, death, or moving abroad, whichever came first.

Mean (SD) follow-up for each participant was 39 years from age 14 onward and 23 years from age 31 onward. The analysis was conducted between 1980 and 2020.

BMI data were collected from participants at the age of 14 and 31 years. Age 14 covariates included smoking, parental socioeconomic status, and age at menarche (for girls). Age 31 covariates included smoking and participants’ educational level.

During the follow-up period, 4.7% of participants experienced stroke. Of these events, 31% were ischemic strokes and 40% were transient ischemic attacks. The remainder were hemorrhagic or other cerebrovascular events.

Using normal weight as a reference, researchers found that the risk for ischemic stroke was over twice as high for women who had been overweight at ages 14 (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.44-4.31) and 31 (HR, 2.13; 95% CI, 1.14-3.97) years. The risk was also considerably higher for women who had obesity at ages 14 (HR, 1.87; 95% CI, 0.76-4.58) and 31 (HR, 2.67; 95% CI, 1.26-5.65) years.

The risk for hemorrhagic stroke was even higher, both among women (HR, 3.49; 95% CI, 1.13-10.7) and men (HR, 5.75; 95% CI, 1.43-23.1) who had obesity at age 31.

No similar associations were found among men, and the findings were independent of earlier or later BMI.

The risk for any cerebrovascular disease related to overweight at age 14 was twice as high among girls vs boys (HR, 2.09; 95% CI, 1.06-4.15), and the risk for ischemic stroke related to obesity at age 31 was nearly seven times higher among women vs men (HR, 6.96; 95% CI, 1.36-35.7).

“Stroke at a young age is rare, so the difference of just a few strokes could have an outsized impact on the risk estimates,” the study authors said. “Also, BMI relies solely on a person’s height and weight; therefore, a high BMI may be a misleading way to define obesity, especially in muscular people who may carry little fat even while weighing more.”
 

Caveats

In an accompanying editorial, Larry Goldstein, MD, chair of the Department of Neurology, University of Kentucky, Lexington, Kentucky, and codirector of the Kentucky Neuroscience Institute, said the study “provides additional evidence of an association between overweight/obesity and stroke in young adults.”

However, Dr. Goldstein added that “while it is tempting to assume that reductions in overweight/obesity in younger populations would translate to lower stroke rates in young adults, this remains to be proven.”

Moreover, it is “always important to acknowledge that associations found in observational studies may not reflect causality.”

This study was supported by Orion Research Foundation, Päivikki and Sakari Sohlberg Foundation, and Paulo Foundation. Dr. Mikkola reported no relevant financial relationships. The other authors’ disclosures are listed on the original paper. Dr. Goldstein reported no relevant financial relationships.

An analysis of more than five decades of health data on 10,000 adults revealed that close to 5% experienced a stroke during the follow-up period, with the risk for ischemic stroke being more than twice as high in women who had obesity as teens or young adults. The risk was even higher for hemorrhagic stroke in both men and women with a history of obesity in youth.

“Our findings suggest that being overweight may have long-term health effects, even if the excess weight is temporary,” lead author Ursula Mikkola, BM, an investigator in the Research Unit of Population Health at the University of Oulu, Oulu, Finland, said in a news release.

Gender Differences

Childhood obesity has been associated with a heightened risk for cerebrovascular disease later in life, but most studies have focused on body mass index (BMI) at a single time point without considering its fluctuations throughout life, the investigators noted.

For the study, investigators used data from the Northern Finland Birth Cohort 1966, a prospective, general population-based birth cohort that followed 10,491 individuals (5185 women) until 2020 or the first stroke, death, or moving abroad, whichever came first.

Mean (SD) follow-up for each participant was 39 years from age 14 onward and 23 years from age 31 onward. The analysis was conducted between 1980 and 2020.

BMI data were collected from participants at the age of 14 and 31 years. Age 14 covariates included smoking, parental socioeconomic status, and age at menarche (for girls). Age 31 covariates included smoking and participants’ educational level.

During the follow-up period, 4.7% of participants experienced stroke. Of these events, 31% were ischemic strokes and 40% were transient ischemic attacks. The remainder were hemorrhagic or other cerebrovascular events.

Using normal weight as a reference, researchers found that the risk for ischemic stroke was over twice as high for women who had been overweight at ages 14 (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.44-4.31) and 31 (HR, 2.13; 95% CI, 1.14-3.97) years. The risk was also considerably higher for women who had obesity at ages 14 (HR, 1.87; 95% CI, 0.76-4.58) and 31 (HR, 2.67; 95% CI, 1.26-5.65) years.

The risk for hemorrhagic stroke was even higher, both among women (HR, 3.49; 95% CI, 1.13-10.7) and men (HR, 5.75; 95% CI, 1.43-23.1) who had obesity at age 31.

No similar associations were found among men, and the findings were independent of earlier or later BMI.

The risk for any cerebrovascular disease related to overweight at age 14 was twice as high among girls vs boys (HR, 2.09; 95% CI, 1.06-4.15), and the risk for ischemic stroke related to obesity at age 31 was nearly seven times higher among women vs men (HR, 6.96; 95% CI, 1.36-35.7).

“Stroke at a young age is rare, so the difference of just a few strokes could have an outsized impact on the risk estimates,” the study authors said. “Also, BMI relies solely on a person’s height and weight; therefore, a high BMI may be a misleading way to define obesity, especially in muscular people who may carry little fat even while weighing more.”
 

Caveats

In an accompanying editorial, Larry Goldstein, MD, chair of the Department of Neurology, University of Kentucky, Lexington, Kentucky, and codirector of the Kentucky Neuroscience Institute, said the study “provides additional evidence of an association between overweight/obesity and stroke in young adults.”

However, Dr. Goldstein added that “while it is tempting to assume that reductions in overweight/obesity in younger populations would translate to lower stroke rates in young adults, this remains to be proven.”

Moreover, it is “always important to acknowledge that associations found in observational studies may not reflect causality.”
