New renin-angiotensin-system (RAS) inhibitor therapy using sacubitril-valsartan (Entresto) is no more likely to cause angioedema than starting out with an ACE inhibitor or angiotensin receptor blocker (ARB).

But the risk climbs when such patients start on an ACE inhibitor or ARB and then switch to sacubitril-valsartan, compared with those prescribed the newer drug, the only available angiotensin receptor-neprilysin inhibitor (ARNI), in the first place.

Those findings and others from a large database analysis, by researchers at the Food and Drug Administration and Harvard Medical School, may clarify and help alleviate a residual safety concern about the ARNI – that it might promote angioedema – that persists after the drug’s major HF trials.  

The angioedema risk increased the most right after the switch to the ARNI from one of the older RAS inhibitors. For example, the overall risk doubled for patients who started with an ARB then switched to sacubitril-valsartan, compared with those who started on the newer drug. But it went up about 2.5 times during the first 14 days after the switch.

A similar pattern emerged for ACE inhibitors, but the increased angioedema risk reached significance only within 2 weeks of the switch from an ACE inhibitor to sacubitril-valsartan compared to starting on the latter.

The analysis, based on data from the FDA’s Sentinel adverse event reporting system, was published in the Journal of the American College of Cardiology.
 

A rare complication, but ...

Angioedema was rare overall in the study, with an unadjusted rate of about 6.75 per 1,000 person-years for users of ACE inhibitors, less than half that rate for ARB users, and only one-fifth that rate for sacubitril-valsartan recipients.

But even a rare complication can be a worry for drugs as widely used as RAS inhibitors. And it’s not unusual for patients cautiously started on an ACE inhibitor or ARB to be switched to sacubitril-valsartan, which is only recently a core guideline–recommended therapy for HF with reduced ejection fraction.

Such patients transitioning to the ARNI, the current study suggests, should probably be watched closely for signs of angioedema for 2 weeks but especially during the first few days. Indeed, the study’s event curves show most of the extra risk “popping up” right after the switch to sacubitril-valsartan, lead author Efe Eworuke, PhD, told this news organization.

The ARNI’s labeling, which states the drug should follow ACE inhibitors only after 36-hour washout period, “has done justice to this issue,” she said. But “whether clinicians are adhering to that, we can’t tell.”

Potentially, patients who miss the 36-hour washout between ACE inhibitors or ARBs and sacubitril-valsartan may account for the excess angioedema risk seen in the analysis, said Dr. Eworuke, with the FDA’s Center for Drug Evaluation and Research, Silver Spring, Md.

But the analysis doesn’t nail down the window of excess risk to only 36 hours. It suggests that patients switching to the ARNI – even those pausing for 36 hours in between drugs – should probably be monitored “2 weeks or longer,” she said. “They could still have angioedema after the washout period.”

Indeed, the “timing of the switch may be critical,” according to an editorial accompanying the report. “Perhaps a longer initial exposure period of ACE inhibitor or ARB,” beyond 2 weeks, “should be considered before switching to an ARNI,” contended Robert L. Page II, PharmD, MSPH, University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences, Aurora.

Moreover, he wrote, the study suggests that “initiation of an ARNI de novo may be safer compared with trialing an ACE inhibitor or ARB then switching to an ARNI,” and “should be a consideration when beginning guideline-directed medical therapy for patients with HF.”
 

New RAS inhibition with ARNI ‘protective’

Compared with ARNI “new users” who had not received any RAS inhibitor in the prior 6 months, patients in the study who switched from an ACE inhibitor to ARNI (41,548 matched pairs) showed a hazard ratio (HR) for angioedema of 1.62 (95% confidence interval [CI], 0.91-2.89), that is, only a “trend,” the report states.

But that trend became significant when the analysis considered only angioedema cases in the first 14 days after the drug switch: HR, 1.98 (95% CI, 1.11-3.53).

Those switching from an ARB to ARNI, compared with ARNI new users (37,893 matched pairs), showed a significant HR for angioedema of 2.03 (95% CI, 1.16-3.54). The effect was more pronounced when considering only angioedema arising in the first 2 weeks: HR, 2.45 (95% CI, 1.36-4.43).

Compared with new use of ACE inhibitors, new ARNI use (41,998 matched pairs) was “protective,” the report states, with an HR for angioedema of 0.18 (95% CI, 0.11-0.29). So was a switch from ACE inhibitors to the ARNI (69,639 matched pairs), with an HR of 0.31 (95% CI, 0.23-0.43).

But compared with starting with an ARB, ARNI new use (43,755 matched pairs) had a null effect on angioedema risk, HR, 0.59 (95% CI, 0.35-1.01); as did switching from an ARB to ARNI (49,137 matched pairs), HR, 0.85 (95% CI, 0.58-1.26).

The analysis has limitations, Dr. Eworuke acknowledged. The comparator groups probably differed in unknown ways given the limits of propensity matching, for example, and because the FDA’s Sentinel system data can reflect only cases that are reported, the study probably underestimates the true prevalence of angioedema.

For example, a patient may see a clinician for a milder case that resolves without a significant intervention, she noted. But “those types of angioedema would not have been captured by our study.”

Dr. Eworuke disclosed that her comments reflect her views and are not those of the Food and Drug Administration; she and the other authors, as well as editorialist Dr. Page, report no relevant financial relationships.

Women who experience preeclampsia during pregnancy are almost twice as likely to have a heart attack or stroke within 20 years of giving birth as pregnant women who did not, according to a new study published in the European Journal of Preventive Cardiology. The risks are especially high in the first decade after giving birth, the researchers found.
 

Preeclampsia is the onset of high blood pressure after the 20th week of pregnancy combined with signs of organ damage, such as excess protein in the urine. It can occur in up to 8% of pregnancies, and the association between preeclampsia and long-term cardiac risks is well-known. But new research suggests these risks appear much earlier in life than expected – as early as age 30 – at a time when women are often not screened for signs of heart trouble

“Targeted interventions cannot wait until women with preeclampsia become eligible for conventional screening programs in middle age,” Sara Hallum, PhD, a coauthor of the study, told this news organization.

Dr. Hallum, who was an epidemiologist at the University of Copenhagen at the time of the study, and colleagues evaluated the medical histories of more than 1.1 million women in Denmark who became pregnant once or twice between 1978 and 2017. Of this group, 3% had experienced preeclampsia. They compared rates of heart attack and stroke between the two groups over time.

While 1.2% of the entire study population had experienced a heart attack or stroke within 20 years of giving birth, 2% of the women with a history of preeclampsia had such an event. Within the first decade after delivery, women with a history of preeclampsia were four times as likely to have a heart attack and three times as likely to have a stroke as other women.

Women aged 30-39 with a history of preeclampsia were nearly five times as likely to have a heart attack and three times as likely to have a stroke as similar-aged women. And if a woman gave birth twice and had preeclampsia only during the second pregnancy, she was at especially high risk for a heart attack, the researchers found.

“Women with a history of preeclampsia should be monitored routinely for modifiable risk factors, particularly for increased blood pressure,” Dr. Hallum said.

The Danish study population is racially homogeneous, so the researchers were not able to distinguish the effects of preeclampsia by racial group. In the United States, strong evidence shows that Black women experience the effects of preeclampsia more than others.
 

A useful clue to cardiac risk

Ellen Seely, MD, an endocrinologist at Brigham and Women’s Hospital in Boston, who specializes in preeclampsia, said physicians are less likely to ask women who have been pregnant if they had experienced preeclampsia than to ask if they smoke or have a family history of heart attacks. As a result, they may miss a looming cardiovascular event, especially in younger women who appear healthy.

“Emerging high blood pressure shouldn’t be ignored” in a seemingly healthy young woman, Dr. Seely said, particularly if that woman has divulged a history of preeclampsia. The doctor’s first step should be to verify hypertension, Dr. Seely said. If high blood pressure is evident, immediate treatment – such as encouraging more physical activity and a healthier diet – should follow. Watchful waiting in such cases is inappropriate, she added.

Although the experience of having preeclampsia is unpleasant and scary, Dr. Seely noted that in at least one way it can prove advantageous. Some women who did not experience preeclampsia will end up having a heart attack, sometimes with no prior warning that anything was amiss. At least a history of preeclampsia provides a clue that women should take care of their hearts.

“The patient carries their history with them wherever they go,” Dr. Seely said. For now, this reality often requires women to mention their pregnancy history even if a provider doesn’t ask. Someday, Dr. Seely said, asking about that history will become just as routine for providers as asking about family history.

The study was funded by the Danish Heart Foundation. Dr. Hallum and Dr. Seely have reported no relevant financial relationships.

Eating in response to stress – known as emotional eating – was significantly associated with several markers of long-term cardiovascular damage, based on data from 1,109 individuals.

“We know diet plays a huge role in cardiovascular disease, but we have focused a lot of work on what you eat, not on what makes you eat” – the current study did exactly that, Martha Gulati, MD, who wasn’t involved in the study, said in an interview.

“Emotional eaters consume food to satisfy their brains rather than their stomachs,” study investigator Nicolas Girerd, MD, of the National Institute of Health and Medical Research (INSERM) and a cardiologist at the University Hospital of Nancy (France), wrote in a press release accompanying the study.

Diet plays a role in the development of cardiovascular disease (CVD), but the impact of eating behavior on long-term cardiovascular health remains unclear, wrote Dr. Girerd and colleagues. Previous research has yielded three common psychological dimensions for eating behavior: emotional eating, restrained eating, and external eating.

Both emotional eating and restrained eating have been linked to cardiovascular disease risk, the researchers noted. “Because of previous findings, we hypothesized that [emotional and/or restrained dimensions of eating behavior] are positively associated with cardiovascular damages, as well as with CV risk factors, such as metabolic syndrome,” they wrote.

In a study published in the European Journal of Preventive Cardiology, the researchers reviewed data from 916 adults and 193 adolescents who were participants in the STANISLAS (Suivi Temporaire Annuel Non-Invasif de la Santé des Lorrains Assurés Sociaux), a longitudinal familial cohort in France. Cardiovascular data were collected at four medical visits as part of a full clinical examination between 1993 and 2016, with one visit every 5-10 years. Roughly one-third (31.0%) of the adults were overweight, 7.9% were obese, and 2.7% were underweight. The median age of the adults at the second visit was 44.7 years; the median age of the adolescent group was 15.2 years.

The primary outcome of cardiovascular damage was measured at the fourth visit. Eating behavior was assessed during the second visit using the Dutch Eating Behaviour Questionnaire (DEBQ), and participants were identified as emotional eaters, restrained eaters, or external eaters.

Among the adults, emotional eating was associated with a 38% increased risk of diastolic dysfunction (odds ratio, 1.38; P = .02), over an average follow-up of 13 years, and this association was mediated by stress in 32% of cases. Emotional eating also was positively linked with a higher carotid-femoral pulse-wave velocity (cfPWV-beta), indicative of increased arterial stiffness. However, none of the three dimensions of eating behavior was associated with cardiovascular damage among the adolescents. In addition, none of the eating-behavior dimensions was tied to metabolic syndrome in the adult group (this association was not measured in the adolescents).

Energy intake had no apparent impact on any associations between eating behavior and CVD measures, Dr. Girerd said in the press release. “We might expect that emotional eaters would consume high-calorie foods, which would in turn lead to cardiovascular problems, but this was not the case. One explanation is that we measured average calorie intake and emotional eaters may binge when stressed and then eat less at other times,” and that the resulting “yo-yo” pattern might negatively affect the heart and blood vessels more than stable food intake, he said.

The study findings were limited by several factors, including the observational design that prevented conclusions of causality, the researchers noted. Other limitations included the use of a nonvalidated scale to measure stress, the lack of data on physical activity, and the use of a mainly healthy population in a limited geographic area, which may limit generalizability, they said.

More research is needed in other contexts and larger cohorts, but the results were strengthened by the large study population and the complete data on eating behaviors and detailed health information, they wrote. The results support previous studies and suggest that patients with emotional eating behavior could benefit from emotion regulation skills training, including cognitive, behavioral, psychological, and interpersonal therapies used in other areas, and from pharmacological treatments, the researchers concluded.

The current study offers a unique and important perspective on the relationship between diet and cardiovascular disease, Dr. Gulati, director of preventive cardiology at the Smidt Heart Institute at Cedars-Sinai Medical Center, Los Angeles, told this news organization.

“Examining eating behavior and its relationship with cardiovascular effects in healthy individuals in this prospective way is quite interesting,” said Dr. Gulati, who was not involved in the study.

The researchers examined healthy people at baseline, inquired about their eating habits, and found that emotional eaters “have evidence of cardiovascular changes when compared with the other groups of eaters, after controlling for other risk factors that are associated with cardiovascular disease when following them for 13 years,” said Dr. Gulati, who was recently named Anita Dann Friedman Endowed Chair in Women’s Cardiovascular Medicine and Research at Cedars-Sinai. “This same finding wasn’t seen in adolescents, but this is probably because they are younger, and the effects aren’t seen. That is reassuring, because it means that the more we address eating behaviors, the more likely we are to reduce their effects to the heart,” she noted.

“This study is important because usually, as cardiologists or anyone in medicine, how we assess diet is by assessment of what food people eat; we don’t usually ask about what triggers them to eat,” Dr. Gulati said. “Eating behaviors based on their triggers ultimately affect food choice and food quantity, and help us understand weight changes during a lifetime,” she said.

“I think we don’t have the data to know that an eating behavior would be able to affect cardiac function,” said Dr. Gulati, “but I think we all might hypothesize that emotional eating may be associated with abnormal diastolic function simply through eating high-density food and weight gain.”

The current study did not show a relationship between eating behavior and metabolic syndrome, in contrast with prior studies, Dr. Gulati noted. However, “the authors report that the association between eating behaviors and diastolic dysfunction was mediated through the stress level,” Dr. Gulati said. “It is important to note that this European population was healthy at baseline, and also relatively healthy 13 years later, which makes these findings even more profound.”

Dr. Gulati said that she agrees with the study authors on the need to assess diet and eating behaviors when assessing cardiovascular risk in patient. “Diet assessment as part of prevention is central, but we should ask not only ‘what do you eat,’ but also ‘what makes you eat,’ ” she said.

More research is needed in other populations, Dr. Gulati added. The current study population was healthy at baseline and follow-up. Studies are needed in cohorts in the United States and in the developing world to see how the results might differ; as well as in rural America or in “food deserts” where food choices are limited.

Another research topic is the interplay between eating behaviors and social determinants of health, in terms of their effect on cardiovascular function, Dr. Gulati said, “and it will be valuable to follow this cohort further to see how these eating behaviors and these intermediate measures translate into cardiovascular outcomes.” Future studies should also examine whether the changes in cardiac function are reversible by interventions to modify eating behavior, particularly emotional eating, she said.

Supporters of the study included the Regional University Hospital Center of Nancy, the French Ministry of Solidarity and Health, and a public grant overseen by the French National Research Agency. The researchers had no financial conflicts to disclose.

Eating in response to stress – known as emotional eating – was significantly associated with several markers of long-term cardiovascular damage, based on data from 1,109 individuals.

“We know diet plays a huge role in cardiovascular disease, but we have focused a lot of work on what you eat, not on what makes you eat” – the current study did exactly that, Martha Gulati, MD, who wasn’t involved in the study, said in an interview.

“Emotional eaters consume food to satisfy their brains rather than their stomachs,” study investigator Nicolas Girerd, MD, of the National Institute of Health and Medical Research (INSERM) and a cardiologist at the University Hospital of Nancy (France), wrote in a press release accompanying the study.

Diet plays a role in the development of cardiovascular disease (CVD), but the impact of eating behavior on long-term cardiovascular health remains unclear, wrote Dr. Girerd and colleagues. Previous research has yielded three common psychological dimensions for eating behavior: emotional eating, restrained eating, and external eating.

Both emotional eating and restrained eating have been linked to cardiovascular disease risk, the researchers noted. “Because of previous findings, we hypothesized that [emotional and/or restrained dimensions of eating behavior] are positively associated with cardiovascular damages, as well as with CV risk factors, such as metabolic syndrome,” they wrote.

In a study published in the European Journal of Preventive Cardiology, the researchers reviewed data from 916 adults and 193 adolescents who were participants in the STANISLAS (Suivi Temporaire Annuel Non-Invasif de la Santé des Lorrains Assurés Sociaux), a longitudinal familial cohort in France. Cardiovascular data were collected at four medical visits as part of a full clinical examination between 1993 and 2016, with one visit every 5-10 years. Roughly one-third (31.0%) of the adults were overweight, 7.9% were obese, and 2.7% were underweight. The median age of the adults at the second visit was 44.7 years; the median age of the adolescent group was 15.2 years.

The primary outcome of cardiovascular damage was measured at the fourth visit. Eating behavior was assessed during the second visit using the Dutch Eating Behaviour Questionnaire (DEBQ), and participants were identified as emotional eaters, restrained eaters, or external eaters.

Among the adults, emotional eating was associated with a 38% increased risk of diastolic dysfunction (odds ratio, 1.38; P = .02), over an average follow-up of 13 years, and this association was mediated by stress in 32% of cases. Emotional eating also was positively linked with a higher carotid-femoral pulse-wave velocity (cfPWV-beta), indicative of increased arterial stiffness. However, none of the three dimensions of eating behavior was associated with cardiovascular damage among the adolescents. In addition, none of the eating-behavior dimensions was tied to metabolic syndrome in the adult group (this association was not measured in the adolescents).

Energy intake had no apparent impact on any associations between eating behavior and CVD measures, Dr. Girerd said in the press release. “We might expect that emotional eaters would consume high-calorie foods, which would in turn lead to cardiovascular problems, but this was not the case. One explanation is that we measured average calorie intake and emotional eaters may binge when stressed and then eat less at other times,” and that the resulting “yo-yo” pattern might negatively affect the heart and blood vessels more than stable food intake, he said.

The study findings were limited by several factors, including the observational design that prevented conclusions of causality, the researchers noted. Other limitations included the use of a nonvalidated scale to measure stress, the lack of data on physical activity, and the use of a mainly healthy population in a limited geographic area, which may limit generalizability, they said.

PARIS – How can the problem of poor treatment compliance in patients with hypertension be resolved? A new therapeutic approach could be a game-changer.

Many approaches have been explored in recent years to make life easier for patients living with chronic conditions that require them to take daily medication: subcutaneous implantable devices, nanogels, and, more specifically in the case of hypertension, renal denervation or small interfering RNA (siRNA) with a long half-life.

It’s siRNA that Michel Azizi, MD, PhD, head of the blood pressure clinic at Georges Pompidou European Hospital (HEGP) in Paris, discussed at the International Meeting of the French Society of Hypertension.

These small molecules have already shown their worth in treating rare diseases such as transthyretin amyloidosis. More recently, treating hypercholesterolemia with the PCSK9 inhibitor inclisiran has proven effective. “One subcutaneous injection of inclisiran reduces LDL cholesterol by 50% for a period of 210 days,” said Dr. Azizi.

The benefit of a new therapeutic siRNA – zilebesiran, administered subcutaneously – in treating hypertension is currently the subject of a phase II clinical trial.

This is a double-stranded RNA. One of the strands is linked to a sugar, N-acetylgalactosamine (GalNAc), which protects these highly fragile siRNA and binds with a very strong affinity in the liver. The second strand binds to a specific area of the RNA to prevent synthesis of the precursor peptide of angiotensin, angiotensinogen. The resulting effect is suppression of the production of angiotensin I and II, which leads to a long-lasting lowering of blood pressure.
 

Lasting efficacy

Phase I studies with zilebesiran have demonstrated a long-term effect, with a reduction of greater than 90% in circulating angiotensinogen over 6 months after a single subcutaneous dose (800 mg). The peak in reduction of circulating angiotensinogen occurs after approximately 3 weeks.

“It’s extremely powerful,” said Dr. Azizi.

Lasting reductions in blood pressure have also been observed, with 24-hour ambulatory blood pressure monitoring showing a reduction in systolic BP of greater than 15 mm Hg 8 weeks after administration of a single dose of zilebesiran (800 mg).

Zilebesiran was also well tolerated, with only mild to moderate reactions at the site of the injection (n = 5/56) and no serious treatment-related adverse events, hypotension, or significant changes in kidney or liver function.

“In terms of benefits, the effect is ongoing. Zilebesiran leads to reduced medication use and causes less variability in blood pressure response. Nevertheless, interfering RNA acts slowly, meaning that zilebesiran would not be suitable for people presenting with a hypertensive crisis. The fact that it blocks the renin-angiotensin system [RAS] for a very long period of time also poses the question of how to reverse its hypotensive effects,” said Dr. Azizi.
 

Unanswered questions

The lasting RAS antagonist and blood pressure–lowering effects pose a potential safety problem in circumstances involving patients in a state of hypovolemia and hypotension who require rapid blood pressure–raising interventions to prevent morbidity and mortality.

In recent studies, Estrellita Uijl et al. have thus examined strategies to counteract the blood pressure–lowering effect of siRNA in spontaneously hypertensive rats.

Fludrocortisone and a high-salt diet were both successful in gradually increasing blood pressure, which returned to its baseline levels on days 5 and 7, respectively. Yet this rate of response would be wholly inadequate in an urgent clinical situation.

However, midodrine could not reduce blood pressure to normal levels, whether administered subcutaneously or orally.

A rapid and short-lasting increase in blood pressure was observed with bolus doses of vasopressors, but clinically, these would need to be administered intravenously to achieve a lasting effect. Such administration would require hospitalization, close monitoring, and the use of human resources and additional health care provisions.

Encouragingly, the laboratory that created this molecule, Alnylam Pharmaceuticals, has come up with an antidote: Reversir. It is a GalNAc-conjugated, single-stranded, high-affinity oligonucleotide complementary to the zilebesiran strand that achieves effective reversal of siRNA activity in 24 hours.

In the future, after the phase 2 trials have been completed, whether or not zilebesiran reduces the incidence of cardiovascular events and mortality remains to be seen. But as for Dr. Azizi, the director of HEGP’s blood pressure clinic in Paris, he has no doubt that “this approach is about to shake up how we treat patients in the cardiovascular field.”
 

On the horizon

Zilebesiran is being studied in phase 2 trials in patients with mild to moderate hypertension not taking antihypertensive drugs (KARDIA-1: 375 patients; double-blind, placebo-controlled, five-arm trial; zilebesiran at 150, 300, and 600 mg twice per year and 300 mg once every 3 months) and in patients whose blood pressure is not controlled (KARDIA-2: 800 patients; initial open-label start-up period of 4 weeks with indapamide/amlodipine/olmesartan, followed by a double-blind, placebo-controlled study over 6 months, then an open-label extension study for up to 12 additional months; zilebesiran at 600 mg on the first day of the initial double-blind period, then every 6 months during the open-label extension period).

Antihypertensive medications that stimulate rather than inhibit type 2 and 4 angiotensin II receptors can lower the rate of dementia among new users of these medications, new research suggests.

Results from a cohort study of more than 57,000 older Medicare beneficiaries showed that the initiation of antihypertensives that stimulate the receptors was linked to a 16% lower risk for incident Alzheimer’s disease and related dementia (ADRD) and an 18% lower risk for vascular dementia compared with those that inhibit the receptors.

“Achieving appropriate blood pressure control is essential for maximizing brain health, and this promising research suggests certain antihypertensives could yield brain benefit compared to others,” lead study author Zachary A. Marcum, PharmD, PhD, associate professor, University of Washington School of Pharmacy, Seattle, told this news organization.

The findings were published online in JAMA Network Open.
 

Medicare beneficiaries

Previous observational studies showed that antihypertensive medications that stimulate type 2 and 4 angiotensin II receptors, in comparison with those that don’t, were associated with lower rates of dementia. However, those studies included individuals with prevalent hypertension and were relatively small.

The new retrospective cohort study included a random sample of 57,773 Medicare beneficiaries aged at least 65 years with new-onset hypertension. The mean age of participants was 73.8 years, 62.9% were women, and 86.9% were White.

Over the course of the study, some participants filled at least one prescription for a stimulating angiotensin II receptor type 2 and 4, such as angiotensin II receptor type 1 blockers, dihydropyridine calcium channel blockers, and thiazide diuretics.

Others participants filled a prescription for an inhibiting type 2 and 4 angiotensin II receptors, including angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, and nondihydropyridine calcium channel blockers.

“All these medications lower blood pressure, but they do it in different ways,” said Dr. Marcum.

The researchers were interested in the varying activity of these drugs at the type 2 and 4 angiotensin II receptors.

For each 30-day interval, they categorized beneficiaries into four groups: a stimulating medication group (n = 4,879) consisting of individuals mostly taking stimulating antihypertensives; an inhibiting medication group (n = 10,303) that mostly included individuals prescribed this type of antihypertensive; a mixed group (n = 2,179) that included a combination of the first two classifications; and a nonuser group (n = 40,413) of individuals who were not using either type of drug.

The primary outcome was time to first occurrence of ADRD. The secondary outcome was time to first occurrence of vascular dementia.

Researchers controlled for cardiovascular risk factors and sociodemographic characteristics, such as age, sex, race/ethnicity, and receipt of low-income subsidy.
 

Unanswered questions

After adjustments, results showed that initiation of an antihypertensive medication regimen that exclusively stimulates, rather than inhibits, type 2 and 4 angiotensin II receptors was associated with a 16% lower risk for incident ADRD over a follow-up of just under 7 years (hazard ratio, 0.84; 95% confidence interval, 0.79-0.90; P < .001).

The mixed regimen was also associated with statistically significant (P = .001) reduced odds of ADRD compared with the inhibiting medications.

As for vascular dementia, use of stimulating vs. inhibiting medications was associated with an 18% lower risk (HR, 0.82; 95% CI, 0.69-0.96; P = .02).

Again, use of the mixed regimen was associated with reduced risk of vascular dementia compared with the inhibiting medications (P = .03).

A variety of potential mechanisms might explain the superiority of stimulating agents when it comes to dementia risk, said Dr. Marcum. These could include, for example, increased blood flow to the brain and reduced amyloid.

“But more mechanistic work is needed as well as evaluation of dose responses, because that’s not something we looked at in this study,” Dr. Marcum said. “There are still a lot of unanswered questions.”
 

Stimulators instead of inhibitors?

The results of the current analysis come on the heels of some previous work showing the benefits of lowering blood pressure. For example, the Systolic Blood Pressure Intervention Trial (SPRINT) showed that targeting a systolic blood pressure below 120 mm Hg significantly reduces risk for heart disease, stroke, and death from these diseases.

But in contrast to previous research, the current study included only beneficiaries with incident hypertension and new use of antihypertensive medications, and it adjusted for time-varying confounding.

Prescribing stimulating instead of inhibiting treatments could make a difference at the population level, Dr. Marcum noted.

“If we could shift the prescribing a little bit from inhibiting to stimulating, that could possibly reduce dementia risk,” he said.

However, “we’re not suggesting [that all patients] have their regimen switched,” he added.

That’s because inhibiting medications still have an important place in the antihypertensive treatment armamentarium, Dr. Marcum noted. As an example, beta-blockers are used post heart attack.

As well, factors such as cost and side effects should be taken into consideration when prescribing an antihypertensive drug.

The new results could be used to set up a comparison in a future randomized controlled trial that would provide the strongest evidence for estimating causal effects of treatments, said Dr. Marcum.
 

‘More convincing’

Carlos G. Santos-Gallego, MD, Icahn School of Medicine at Mount Sinai, New York, said the study is “more convincing” than previous related research, as it has a larger sample size and a longer follow-up.

“And the exquisite statistical analysis gives more robustness, more solidity, to the hypothesis that drugs that stimulate type 2 and 4 angiotensin II receptors might be protective for dementia,” said Dr. Santos-Gallego, who was not involved with the research.

However, he noted that the retrospective study had some limitations, including the underdiagnosis of dementia. “The diagnosis of dementia is, honestly, very poorly done in the clinical setting,” he said.

As well, the study could be subject to “confounding by indication,” Dr. Santos-Gallego said. “There could be a third variable, another confounding factor, that’s responsible both for the dementia and for the prescription of these drugs,” he added.

For example, he noted that comorbidities such as atrial fibrillation, myocardial infarction, and heart failure might increase the risk of dementia.

He agreed with the investigators that a randomized clinical trial would address these limitations. “All comorbidities would be equally shared” in the randomized groups, and all participants would be given “a specific test for dementia at the same time,” Dr. Santos-Gallego said.

Still, he noted that the new results are in keeping with hypertension guidelines that recommend stimulating drugs.

“This trial definitely shows that the current hypertension guidelines are good treatment for our patients, not only to control blood pressure and not only to prevent infarction to prevent stroke but also to prevent dementia,” said Dr. Santos-Gallego.

Also commenting for this news organization, Heather Snyder, PhD, vice president of medical and scientific relations at the Alzheimer’s Association, said the new data provide “clarity” on why previous research had differing results on the effect of antihypertensives on cognition.

Among the caveats of this new analysis is that “it’s unclear if the demographics in this study are fully representative of Medicare beneficiaries,” said Dr. Snyder.

She, too, said a clinical trial is important “to understand if there is a preventative and/or treatment potential in the medications that stimulate type 2 and 4 angiotensin II receptors.”

The study received funding from the National Institute on Aging. Dr. Marcum and Dr. Santos-Gallego have reported no relevant financial relationships.

Women in the United States who followed a Mediterranean-style diet – heavy on fresh foods, fish, and olive oil – around the time of conception had lower risk of developing a pregnancy complication, results of a large new study suggest.

The study included 7,798 women who had not given birth before. The group was geographically, racially, and ethnically diverse.

Researchers led by Nour Makarem, PhD, MS, with the department of epidemiology, Columbia University, New York, published their results in JAMA Network Open.

“Generally, higher intakes of vegetables, fruits, legumes, fish, and whole grains and lower intakes of red and processed meat were associated with lower risk of APOs [adverse pregnancy outcomes],” the authors wrote.
 

21% lower risk of complications

The investigators found that women in the study – who were part of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, which enrolled 10,038 women between Oct. 1, 2010, and Sept. 30, 2013, and scored high on adherence to a Mediterranean diet – had a 21% lower risk of developing any adverse pregnancy outcome (APO) than those who had low adherence. And the better the adherence, the lower the risk of adverse outcomes, especially preeclampsia or eclampsia and gestational diabetes, the researchers wrote.

The research team also studied how following the diet correlated with gestational high blood pressure, preterm birth, delivery of a small-for-gestational-age infant, and stillbirth.

Women were scored on consumption of nine components: vegetables (excluding potatoes), fruits, nuts, whole grains, legumes, fish, monounsaturated to saturated fat ratio, red and processed meats, and alcohol.
 

No differences by race, ethnicity, or BMI

There were no differences in adverse pregnancy outcomes by race, ethnicity, or the woman’s body mass index before pregnancy, but associations were stronger in the women who were 35 years or older, according to the paper.

The authors pointed out that the women in the study had access to prenatal care at a large academic medical center during their first 3 months of pregnancy so the study may actually underestimate the importance of the diet in the pregnancy outcomes.

Christina Han, MD, division director of maternal-fetal medicine at University of California, Los Angeles, who was not part of the study, said that the results make sense as the researchers looked at the time of conception, which is a time that reflects the way a person chooses to live their life.

“We know that your health state as you enter pregnancy can significantly affect your outcomes for that pregnancy,” she said. “We’ve known for decades now that a Mediterranean diet is good for just about everybody.”
 

Unequal access to foods on diet

Dr. Han said that, while it’s great the researchers were able to confirm the benefit of the Mediterranean diet, it highlights inequity as lower income people are not as likely to be able to afford fresh fruits and vegetables and fish.

“This is a call to arms for our food distribution system to even out the big divide in what patients have access to,” Dr. Han said.

She noted that most of the women in this study were married, non-Hispanic White, and had higher levels of education which may make it hard to generalize these results to the general population.

A limitation of the study is that the women were asked to report what they ate themselves, which can be less accurate than when researchers record what is eaten in a controlled setting.

The researchers suggested a next step: “Long-term intervention studies are needed to assess whether promoting a Mediterranean-style diet around the time of conception and throughout pregnancy can prevent APOs.”

Dr. Makarem reported receiving grants from the National Institutes of Health and the American Heart Association outside the submitted work. One coauthor reported receiving grants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development during the study. One coauthor reported receiving personal fees for serving on the board of directors for iRhythm and from fees paid through Cedars-Sinai Medical Center from Abbott Diagnostics and Sanofi outside the submitted work, and one coauthor reported serving as a clinical end point committee member for GlaxoSmithKline outside the submitted work. No other disclosures were reported. Dr. Han reported no relevant financial relationships.

She noted that most of the women in this study were married, non-Hispanic White, and had higher levels of education which may make it hard to generalize these results to the general population.

A limitation of the study is that the women were asked to report what they ate themselves, which can be less accurate than when researchers record what is eaten in a controlled setting.

The researchers suggested a next step: “Long-term intervention studies are needed to assess whether promoting a Mediterranean-style diet around the time of conception and throughout pregnancy can prevent APOs.”

Leading cardiology societies have issued a “call for action” on a global scale to reinvent randomized clinical trials fit for the 21st century.

“Randomized trials are an essential tool for reliably assessing the effects of treatments, but they have become too costly and too burdensome,” first author Louise Bowman, University of Oxford, England, told this news organization. “We urgently need to modernize our approach to clinical trials in order to continue to improve patient care.”

The joint opinion is from the European Society of Cardiology, the American Heart Association, the American College of Cardiology, and the World Heart Federation. It was simultaneously published online in the European Heart Journal, Circulation, Journal of the American College of Cardiology, and Global Heart.

The authors note that the availability of large-scale “real-world” data is increasingly being touted as a way to bypass the challenges of conducting randomized trials. Yet, observational analyses of real-world data “are not a suitable alternative to randomization,” Prof. Bowman said.

Cardiology has historically led the way in transforming clinical practice with groundbreaking “mega-trials,” such as the International Study of Infarct Survival (ISIS), Gruppo Italiano per lo Studio della Streptochinasi nell’Infarto (GISSI), and Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO).

But over the past 25 years, there has been a huge increase in the rules and related bureaucracy governing clinical trials, which hinders the ability to conduct trials swiftly and affordably, the authors point out.

The COVID-19 pandemic has shown that important clinical trials can be performed quickly and efficiently in busy hospitals, they note.

“The RECOVERY trial in COVID-19 has been an excellent example of this, with results that are estimated to have saved around 1 million lives worldwide within just 1 year,” Prof. Bowman told this news organization.

A Good Clinical Trials Collaborative made up of key stakeholders recently developed new guidelines designed to promote better, more efficient randomized controlled trials.

“If widely adopted and used alongside valuable 21st century electronic health records, we could transform the clinical trials landscape and do many more high-quality trials very cost-effectively,” Prof. Bowman said.

“Widespread adoption and implementation of the revised guidelines will require collaboration with a wide range of national and international organizations, including patient, professional, academic, and industry groups, funders and government organizations, and ethics, health policy, and regulatory bodies,” Prof. Bowman acknowledged.

“This is work that the Good Clinical Trials Collaborative is leading. It is hoped that this endorsement by the joint cardiovascular societies will increase awareness and provide valuable support to his important work,” she added.

No commercial funding was received. The authors have disclosed no relevant financial relationships.

Lupin Pharmaceuticals is recalling four lots of quinapril tablets because of unacceptable levels of the nitrosamine impurity, N-nitroso-quinapril, a potential carcinogen.

Nitrosamines “may increase the risk of cancer if people are exposed to them above acceptable levels over long periods of time,” the company says in a recall notice posted on the Food and Drug Administration website.

Lupin says it “has received no reports of illness that appear to relate to this issue.”

Quinapril is an ACE inhibitor used to treat hypertension. Lupin stopped marketing quinapril tablets in September 2022.

The recalled product – quinapril tablets USP 20 mg and 40 mg – are packaged in 90-count bottles and were distributed nationwide to U.S. wholesalers, drug chains, mail order pharmacies, and supermarkets between March 15, 2021, and Sept. 1, 2022.

Lupin is notifying customers to immediately stop distribution of the recalled product and is arranging for the affected product lots to be returned to the company.

The company is advising patients to continue taking their medication and to contact their pharmacist, physician, or healthcare professional for advice regarding an alternative treatment.

Questions regarding this recall should be directed to Inmar Rx Solutions at (877) 538-8445 Monday to Friday between 9:00 a.m. to 5:00 p.m. EST.

Patients and physicians are also advised to report any adverse events or side effects related to the affected products to MedWatch, the FDA’s Safety Information and Adverse Event Reporting program.

Pfizer recalled several lots of quinapril owing to the presence of the same impurity in March 2022and again in April.

Sleep-disordered breathing was significantly associated with increased odds of preeclampsia and with greater arterial stiffness in high-risk pregnancies, based on data from 181 individuals.

The intermittent hypoxia resulting from sleep-disordered breathing (SDB) has been linked to cardiovascular disease and hypertension, wrote Kim Phan, PhD, of McGill University, Montreal, and colleagues.

SDB has been associated with increased preeclampsia risk, and women with preeclampsia show increased arterial stiffness, but an association between SDB and arterial stiffness in pregnancy has not been explored, they said.

In a study published in the American Journal of Obstetrics & Gynecology, the researchers reviewed data from 181 women with high-risk singleton pregnancies recruited from two tertiary obstetrics clinics in Montreal. High-risk pregnancy was defined as meeting at least one of the following criteria: age 35 years and older, body mass index 25 kg/m² or higher, chronic hypertension, preexisting diabetes mellitus, preexisting renal disease, or personal or first-degree relative with a history of preeclampsia.

Participants were assessed at each trimester via the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and Restless Legs Syndrome questionnaire. Sleep-disordered breathing was defined as loud snoring or witnessed sleep apneas at least three times a week. Arterial stiffness was assessed via applanation tonometry every 4 weeks from baseline throughout pregnancy.

Overall, 23% of the study population met the criteria for SDB; SDB in the first or second trimester was associated with a significantly increased risk of preeclampsia (odds ratio 3.4). The effect of SDB on preeclampsia was increased in women who reported excessive daytime sleepiness, defined as scores higher than 10 on the Epworth Sleepiness Scale. The odds ratio for preeclampsia in the first or second trimester increased to 5.7 in women with hypersomnolence in addition to SDB. The risk of preeclampsia was even higher (OR 8.2) in the third trimester.

Self-reported total sleep time decreased in the second and third trimesters compared with the first, but reports of excessive daytime sleepiness remained consistent throughout the pregnancies, the researchers noted.

The results highlight the need to screen pregnant women for SDB in all three trimesters; however, “future studies will need to assess the incremental benefit of integrating SDB into risk assessment calculators in pregnancy,” the researchers wrote in their discussion. Randomized trials are needed to determine the value of interventions such as continuous positive airway pressure to reduce arterial stiffness and the risks of hypertensive disorders of pregnancy, they said. More data also are needed to examine the role of excessive daytime sleepiness as a modifier of arterial stiffness and preeclampsia risk, they noted.

The findings were limited by the prospective design, which prevents conclusions of causality, the researchers noted. Other limitations included the focus on high-risk pregnancy, which may limit generalizability, and the use of symptoms, not sleep recordings, to identify SDB, they said.

However, the results show an independent association between SDB and arterial stiffness during pregnancy, and offer potentially useful insights into the mechanisms of SDB-associated cardiovascular conditions, they noted.

“This work may inform future studies exploring the value of using arterial stiffness, as an early noninvasive indicator of subclinical vascular dysfunction in pregnant women with SDB,” they concluded.

The study was supported by the Fonds de recherche du Quebec – Sante (FRQS), Heart and Stroke Foundation of Canada, McGill University’s academic enrichment fund, and the Canadian Foundation for Women’s Health. The researchers had no financial conflicts to disclose.

CHICAGO – Black patients with heart failure with reduced ejection fraction (HFrEF) may receive more benefit from treatment with a sodium-glucose cotransporter-2 (SGLT2) inhibitor than do White patients, according to a new report.

A secondary analysis of data collected from the pivotal trials that assessed the SGLT2 inhibitor empagliflozin in patients with HFrEF, EMPEROR-Reduced, and in patients with heart failure with preserved ejection fraction (HFpEF), EMPEROR-Preserved, was presented by Subodh Verma, MD, PhD, at the American Heart Association scientific sessions.

Mitchel L. Zoler/MDedge News

The “hypothesis-generating” analysis of data from EMPEROR-Reduced showed “a suggestion of a greater benefit of empagliflozin” in Black, compared with White patients, for the study’s primary endpoint (cardiovascular death or hospitalization for heart failure) as well as for first and total hospitalizations for heart failure, he reported.

However, a similar but separate analysis that compared Black and White patients with heart failure who received treatment with a second agent, dapagliflozin, from the same SGLT2-inhibitor class did not show any suggestion of heterogeneity in the drug’s effect based on race.
 

Race-linked heterogeneity in empagliflozin’s effect

In EMPEROR-Reduced, which randomized 3,730 patients with heart failure and a left ventricular ejection fraction of 40% or less, treatment of White patients with empagliflozin (Jardiance) produced a nonsignificant 16% relative reduction in the rate of the primary endpoint, compared with placebo, during a median 16-month follow-up.

By contrast, among Black patients, treatment with empagliflozin produced a significant 56% reduction in the primary endpoint, compared with placebo-treated patients, a significant heterogeneity (P = .02) in effect between the two race subgroups, said Dr. Verma, a cardiac surgeon and professor at the University of Toronto.

The analysis he reported used combined data from EMPEROR-Reduced and the companion trial EMPEROR-Preserved, which randomized 5,988 patients with heart failure and a left ventricular ejection fraction greater than 40% to treatment with either empagliflozin or placebo and followed them for a median of 26 months.

To assess the effects of the randomized treatments in the two racial subgroups, Dr. Verma and associates used pooled data from both trials, but only from the 3,502 patients enrolled in the Americas, which included 3,024 White patients and 478 Black patients. Analysis of the patients in this subgroup who were randomized to placebo showed a significantly excess rate of the primary outcome among Blacks, who tallied 49% more of the primary outcome events during follow-up than did White patients, Dr. Verma reported. The absolute rate of the primary outcome without empagliflozin treatment was 13.15 events/100 patient-years of follow-up in White patients and 20.83 events/100 patient-years in Black patients.

The impact of empagliflozin was not statistically heterogeneous in the total pool of patients that included both those with HFrEF and those with HFpEF. The drug reduced the primary outcome incidence by a significant 20% in White patients, and by a significant 44% among Black patients.

But this point-estimate difference in efficacy, when coupled with the underlying difference in risk for an event between the two racial groups, meant that the number-needed-to-treat to prevent one primary outcome event was 42 among White patients and 12 among Black patients.
 

Race-linked treatment responses only in HFrEF

This suggestion of an imbalance in treatment efficacy was especially apparent among patients with HFrEF. In addition to the heterogeneity for the primary outcome, the Black and White subgroups also showed significantly divergent results for the outcomes of first hospitalization for heart failure, with a nonsignificant 21% relative reduction with empagliflozin treatment in Whites but a significant 65% relative cut in this endpoint with empagliflozin in Blacks, and for total hospitalizations for heart failure, which showed a similar level of significant heterogeneity between the two race subgroups.

In contrast, the patients with HFpEF showed no signal at all for heterogeneous outcome rates between Black and White subgroups.

One other study outcome, change in symptom burden measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ), also showed suggestion of a race-based imbalance. The adjusted mean difference from baseline in the KCCQ clinical summary score was 1.50 points higher with empagliflozin treatment, compared with placebo among all White patients (those with HFrEF and those with HFpEF), and compared with a 5.25-point increase with empagliflozin over placebo among all Black patients with heart failure in the pooled American EMPEROR dataset, a difference between White and Black patients that just missed significance (P = .06). Again, this difference was especially notable and significant among the patients with HFrEF, where the adjusted mean difference in KCCQ was a 0.77-point increase in White patients and a 6.71-point increase among Black patients (P = .043),

These results also appeared in a report published simultaneously with Dr. Verma’s talk.

But two other analyses that assessed a possible race-based difference in empagliflozin’s effect on renal protection and on functional status showed no suggestion of heterogeneity.

Dr. Verma stressed caution about the limitations of these analyses because they involved a relatively small number of Black patients, and were possibly subject to unadjusted confounding from differences in baseline characteristics between the Black and White patients.

Black patients also had a number-needed-to-treat advantage with dapagliflozin

The finding that Black patients with heart failure potentially get more bang for the buck from treatment with an SGLT2 inhibitor by having a lower number needed to treat also showed up in a separate report at the meeting that assessed the treatment effect from dapagliflozin (Farxiga) in Black and White patients in a pooled analysis of the DAPA-HF pivotal trial of patients with HFrEF and the DELIVER pivotal trial of patients with HFpEF. The pooled cohort included a total of 11,007, but for the analysis by race the investigators also limited their focus to patients from the Americas with 2,626 White patients and 381 Black patients.

Mitchel L. Zoler/MDedge News

Assessment of the effect of dapagliflozin on the primary outcome of cardiovascular death or hospitalization for heart failure among all patients, both those with HFrEF and those with HFpEF, again showed that event rates among patients treated with placebo were significantly higher in Black, compared with White patients, and this led to a difference in the number needed to treat to prevent one primary outcome event of 12 in Blacks and 17 in Whites, Jawad H. Butt, MD said in a talk at the meeting.

Although treatment with dapagliflozin reduced the rate of the primary outcome in this subgroup of patients from the DAPA-HF trial and the DELIVER trial by similar rates in Black and White patients, event rates were higher in the Black patients resulting in “greater benefit in absolute terms” for Black patients, explained Dr. Butt, a cardiologist at Rigshospitalet in Copenhagen.

But in contrast to the empagliflozin findings reported by Dr. Verma, the combined data from the dapagliflozin trials showed no suggestion of heterogeneity in the beneficial effect of dapagliflozin based on left ventricular ejection fraction. In the Black patients, for example, the relative benefit from dapagliflozin on the primary outcome was consistent across the full spectrum of patients with HFrEF and HFpEF.

EMPEROR-Reduced and EMPEROR-Preserved were sponsored by Boehringer Ingelheim and Lilly, the companies that jointly market empagliflozin (Jardiance). The DAPA-HF and DELIVER trials were sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Verma has received honoraria, research support, or both from AstraZeneca, Boehringer Ingelheim, and Lilly, and from numerous other companies. Dr. Butt has been a consultant to and received travel grants from AstraZeneca, honoraria from Novartis, and has been an adviser to Bayer.

The absolute rate of the primary outcome without empagliflozin treatment was 13.15 events/100 patient-years of follow-up in White patients and 20.83 events/100 patient-years in Black patients.

The impact of empagliflozin was not statistically heterogeneous in the total pool of patients that included both those with HFrEF and those with HFpEF. The drug reduced the primary outcome incidence by a significant 20% in White patients, and by a significant 44% among Black patients.

But this point-estimate difference in efficacy, when coupled with the underlying difference in risk for an event between the two racial groups, meant that the number-needed-to-treat to prevent one primary outcome event was 42 among White patients and 12 among Black patients.
 

Race-linked treatment responses only in HFrEF

This suggestion of an imbalance in treatment efficacy was especially apparent among patients with HFrEF. In addition to the heterogeneity for the primary outcome, the Black and White subgroups also showed significantly divergent results for the outcomes of first hospitalization for heart failure, with a nonsignificant 21% relative reduction with empagliflozin treatment in Whites but a significant 65% relative cut in this endpoint with empagliflozin in Blacks, and for total hospitalizations for heart failure, which showed a similar level of significant heterogeneity between the two race subgroups.

In contrast, the patients with HFpEF showed no signal at all for heterogeneous outcome rates between Black and White subgroups.

One other study outcome, change in symptom burden measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ), also showed suggestion of a race-based imbalance. The adjusted mean difference from baseline in the KCCQ clinical summary score was 1.50 points higher with empagliflozin treatment, compared with placebo among all White patients (those with HFrEF and those with HFpEF), and compared with a 5.25-point increase with empagliflozin over placebo among all Black patients with heart failure in the pooled American EMPEROR dataset, a difference between White and Black patients that just missed significance (P = .06). Again, this difference was especially notable and significant among the patients with HFrEF, where the adjusted mean difference in KCCQ was a 0.77-point increase in White patients and a 6.71-point increase among Black patients (P = .043),

These results also appeared in a report published simultaneously with Dr. Verma’s talk.

But two other analyses that assessed a possible race-based difference in empagliflozin’s effect on renal protection and on functional status showed no suggestion of heterogeneity.

Dr. Verma stressed caution about the limitations of these analyses because they involved a relatively small number of Black patients, and were possibly subject to unadjusted confounding from differences in baseline characteristics between the Black and White patients.

Black patients also had a number-needed-to-treat advantage with dapagliflozin

The finding that Black patients with heart failure potentially get more bang for the buck from treatment with an SGLT2 inhibitor by having a lower number needed to treat also showed up in a separate report at the meeting that assessed the treatment effect from dapagliflozin (Farxiga) in Black and White patients in a pooled analysis of the DAPA-HF pivotal trial of patients with HFrEF and the DELIVER pivotal trial of patients with HFpEF. The pooled cohort included a total of 11,007, but for the analysis by race the investigators also limited their focus to patients from the Americas with 2,626 White patients and 381 Black patients.

Assessment of the effect of dapagliflozin on the primary outcome of cardiovascular death or hospitalization for heart failure among all patients, both those with HFrEF and those with HFpEF, again showed that event rates among patients treated with placebo were significantly higher in Black, compared with White patients, and this led to a difference in the number needed to treat to prevent one primary outcome event of 12 in Blacks and 17 in Whites, Jawad H. Butt, MD said in a talk at the meeting.

Although treatment with dapagliflozin reduced the rate of the primary outcome in this subgroup of patients from the DAPA-HF trial and the DELIVER trial by similar rates in Black and White patients, event rates were higher in the Black patients resulting in “greater benefit in absolute terms” for Black patients, explained Dr. Butt, a cardiologist at Rigshospitalet in Copenhagen.

But in contrast to the empagliflozin findings reported by Dr. Verma, the combined data from the dapagliflozin trials showed no suggestion of heterogeneity in the beneficial effect of dapagliflozin based on left ventricular ejection fraction. In the Black patients, for example, the relative benefit from dapagliflozin on the primary outcome was consistent across the full spectrum of patients with HFrEF and HFpEF.

EMPEROR-Reduced and EMPEROR-Preserved were sponsored by Boehringer Ingelheim and Lilly, the companies that jointly market empagliflozin (Jardiance). The DAPA-HF and DELIVER trials were sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Verma has received honoraria, research support, or both from AstraZeneca, Boehringer Ingelheim, and Lilly, and from numerous other companies.

CHICAGO – Black patients with heart failure with reduced ejection fraction (HFrEF) may receive more benefit from treatment with a sodium-glucose cotransporter-2 (SGLT2) inhibitor than do White patients, according to a new report.

A secondary analysis of data collected from the pivotal trials that assessed the SGLT2 inhibitor empagliflozin in patients with HFrEF, EMPEROR-Reduced, and in patients with heart failure with preserved ejection fraction (HFpEF), EMPEROR-Preserved, was presented by Subodh Verma, MD, PhD, at the American Heart Association scientific sessions.

The “hypothesis-generating” analysis of data from EMPEROR-Reduced showed “a suggestion of a greater benefit of empagliflozin” in Black, compared with White patients, for the study’s primary endpoint (cardiovascular death or hospitalization for heart failure) as well as for first and total hospitalizations for heart failure, he reported.

However, a similar but separate analysis that compared Black and White patients with heart failure who received treatment with a second agent, dapagliflozin, from the same SGLT2-inhibitor class did not show any suggestion of heterogeneity in the drug’s effect based on race.
 

Race-linked heterogeneity in empagliflozin’s effect

In EMPEROR-Reduced, which randomized 3,730 patients with heart failure and a left ventricular ejection fraction of 40% or less, treatment of White patients with empagliflozin (Jardiance) produced a nonsignificant 16% relative reduction in the rate of the primary endpoint, compared with placebo, during a median 16-month follow-up.

By contrast, among Black patients, treatment with empagliflozin produced a significant 56% reduction in the primary endpoint, compared with placebo-treated patients, a significant heterogeneity (P = .02) in effect between the two race subgroups, said Dr. Verma, a cardiac surgeon and professor at the University of Toronto.

The analysis he reported used combined data from EMPEROR-Reduced and the companion trial EMPEROR-Preserved, which randomized 5,988 patients with heart failure and a left ventricular ejection fraction greater than 40% to treatment with either empagliflozin or placebo and followed them for a median of 26 months.
