Having a “high normal” serum sodium level in midlife, which reflects less than optimal fluid intake, is associated with an increased risk for left ventricular hypertrophy – a heart failure (HF) precursor – and for HF itself, in older age, a new study suggests.

Compared with middle-aged adults in the Atherosclerosis Risk in Communities (ARIC) study with normal serum sodium, those with levels of 142-146 mmol/L were more likely to have left ventricular hypertrophy or HF when they were in their 70s and 80s, independent of other risk factors.  

Natalia Dmitrieva, PhD, a research scientist at the National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, Md., presented the study findings in an e-poster on Aug. 27 at the European Society of Cardiology (ESC) Congress 2021.

“Our study suggests that maintaining good hydration can prevent or at least slow down the changes within the heart that lead to heart failure,” she said in a statement from the ESC.

It “suggests that all adults should aim for eight to ten glasses of liquid [daily] and keep salt intake low,” Dr. Dmitrieva said in an interview.

However, people should not rely completely on thirst, she cautioned, especially in middle age, when thirst sensation starts to deteriorate. And too much fluid intake can be harmful and even dangerous.

Normal serum sodium is usually defined as 135-146 mmol/L, Dr. Dmitrieva explained, and this study involved only patients in ARIC with sodium levels in this range, to try to exclude patients with genetic or water-salt balance diseases.

The findings suggest that a serum sodium level of 142-146 mmol/L, which would not be flagged as abnormal by a test lab, “can be used by clinicians as a warning sign” for a patient’s increased risk for HF, she noted.

Clinicians should explain this risk to patients and advise them to drink at least 2 L per day. However, people should not try to reduce their sodium levels by drinking more than 2 to 3 L per day, she cautioned, which can be harmful and even deadly, and they should consult their doctors.
 

Watch hydration

“An important finding of this study is that sodium values considered ‘normal’ may also be deleterious,” Jacob Joseph, MD, director, heart failure program, VA Boston Healthcare System, who was not involved with this study, said in an interview.

“These results are similar to studies we have conducted in heart failure with preserved ejection fraction,” noted Dr. Joseph, associate professor of medicine at Harvard Medical School, Boston.

Their studies showed a U-shaped relationship between serum sodium values and adverse outcomes, “indicating an ‘optimal’ range of serum sodium value that was narrower than the accepted normal laboratory value range,” he noted.

The study by Dmitrieva et al. was observational and the findings would need to be verified in a randomized controlled trial, Dr. Joseph pointed out; however, the research “supports the idea that even a high normal sodium level may indicate risk of future heart failure.

“Hence, patients should pay attention to hydration,” he continued, and “clinicians should not assume that a sodium level of 142 mmol/L is appropriate and should ensure that patients are paying attention to hydration.

“In today’s busy and stress-filled lifestyle, it is easy to forget about adequate fluid intake,” Dr. Joseph added. 
 

More than 15,000 adults followed for 25 Years

To investigate the relationship between serum sodium, hydration, and future heart failure, Dr. Dmitrieva and colleagues analyzed data from 15,792 adults in ARIC who were 44-66 years of age at study entry, with serum sodium levels from 135 to 146 mmol/L.

The participants were evaluated over five visits until they reached 70-90 years.

They were divided into four groups based on their average serum sodium concentrations at study visits one and two (conducted in the first 3 years): 135 -139.5 mmol/L, 140-141.5 mmol/L, 142-143.5 mmol/L, and 144-146 mmol/L.

The researchers determined the percentage of people in each group who developed HF and left ventricular hypertrophy at visit five (25 years after study enrollment).

Patients with higher serum sodium levels had a significantly higher risk for HF and left ventricular hypertrophy, after adjustment for other risk factors, including age, blood pressure, kidney function, blood cholesterol, blood glucose, body mass index, sex, and smoking status.

Every 1 mmol/L increase in serum sodium concentration in midlife was associated with 1.20 and 1.11 increased odds of developing left ventricular hypertrophy and HF, respectively, 25 years later.

“More studies are needed to find out what proportion of people with serum sodium 142 mmol/L and higher have this [serum sodium] level because they do not drink enough and will be able to reduce it by making sure they consistently drink 2 to 2.5 L per day,” said Dr. Dmitrieva.

“It is likely that for some people, other factors that are related to genetics or diseases affecting water-salt balance could be causing their increased serum sodium levels,” she speculated.

The study was funded by the Intramural Program of the National Heart, Lung, and Blood Institute. The authors and Dr. Joseph have no relevant financial disclosures.

Among middle-aged people without heart disease, drinking up to three cups of coffee per day was linked with a lower risk for stroke or death over the next decade, along with better heart structure and function, in a large, observational study.

Specifically, light-to-moderate coffee drinking, defined as 0.5 to 3 cups per day, was associated with a 21% lower risk for stroke, a 17% lower risk for death from cardiovascular disease (CVD), and a 12% lower risk for death from all causes, as well as more favorable cardiac MRI findings, compared with nondrinkers (< 0.5 cup per day) during a median 11-year follow-up.

Heavy coffee drinkers, defined as those consuming more than three cups per day, on the other hand, likewise had more favorable cardiac MRI findings, but with similar (not lower) rates of stroke and CVD or all-cause mortality compared with nondrinkers.

Judit Simon, MD, presented these findings, from close to 500,000 participants in the UK Biobank study, at a press conference before an e-poster session at the virtual annual congress of the European Society of Cardiology.

“To our knowledge, this is the largest study to systematically assess the cardiovascular effects of regular coffee consumption in a population without diagnosed heart disease,” Dr. Simon, a PhD student at the Heart and Vascular Centre, Semmelweis University, Budapest, Hungary, said in an ESC press release.

The results “suggest that regular coffee consumption is safe, as even high daily intake was not associated with adverse cardiovascular outcomes and all-cause mortality after a follow-up of 10 to 15 years,” she said.

The imaging analysis showed that “compared with participants who did not drink coffee regularly, daily consumers had healthier sized and better functioning hearts,” Dr. Simon continued, “consistent with reversing the detrimental effects of aging on the heart.”

“The observed benefits might be partly explained by positive alterations in cardiac structure and function,” she speculated, adding that further studies are needed to explain the underlying mechanisms.

Instant coffee most popular

In this population, the coffee drinkers mostly drank instant coffee (55%), followed by filtered/ground (23%), decaffeinated (20%), or other types of coffee (2%), Dr. Simon said in an interview.

Risk for myocardial infarction (MI) or heart failure did not significantly differ for different categories of coffee intake, she added. The researchers did not study the effect of coffee consumption on atrial fibrillation (AF), she noted. 

Study limitations, Dr. Simon acknowledged, include that it was observational, so it cannot show causation, and that coffee consumption was self-reported in a questionnaire.

Invited to comment, Alice H. Lichtenstein, DSc, who was not involved with the research, said, “Consistent with prior data, this new study indicates there is no adverse effect of coffee consumption on cardiovascular health and there may be a benefit.”

However, “because of the nature of the data, it would not be recommended that an individual starting drinking coffee to improve cardiovascular health,” added Dr. Lichtenstein, director and senior scientist at the Cardiovascular Nutrition Laboratory at Tufts University, Boston.

But if people already drink coffee, “it is fine to continue, assuming that the coffee drinks are not high in added sugar and cream,” she said in an interview.
 

Coffee intake, CVD outcomes, and heart structure

To study the relationship between coffee intake and incident MI, stroke, and death, as well as heart structure, the researchers examined data from the UK Biobank, which recruited 500,000 people aged 40-69 years in 2006-2010 from across the United Kingdom.

They identified 468,629 participants with no signs of heart disease at recruitment and an average age of 56 years, of whom 56% were women.

The participants were divided into three groups based on usual coffee intake: none (22% of participants), light-to-moderate (58%), and high (20%).

Median tea intake was three cups per day overall, four cups per day in noncoffee drinkers, three cups per day in light-to-moderate coffee drinkers, and one cup per day in high coffee drinkers.

Compared to not drinking coffee, light-to-moderate coffee consumption was associated with lower risks for all-cause death (hazard ratio [HR], 0.88; P < .001), CVD death (HR, 0.83; P = .006), and stroke (HR, 0.79; P = .037), over a median follow-up of 11 years, after adjustment for sex; weight; height; smoking status; physical activity; high blood pressure; diabetes; cholesterol level; socioeconomic status; and usual intake of alcohol, meat, tea, fruit, and vegetables.  

In the 30,650 participants who had cardiac MRI data, the study found that compared with not drinking coffee, both light-to-moderate and high coffee consumption were associated with significantly increased left and right ventricular end-systolic and end-diastolic volumes, and with greater left ventricular mass (all P < .001).

These differences were small but significant, Dr. Simon stressed, because this was a cohort of healthy patients who did not have CVD (heart failure, MI, stroke, AF) at baseline, although some had hypertension or diabetes.

Press conference chairperson, Steen Dalby Kristensen, MD, professor and cardiologist, Aarhus University Hospital, Denmark, a coffee lover himself, wanted to know if an amount such as two, three, or four cups of coffee was optimal to see these heart benefits, and whether there were differences in benefits seen with drinking different types of coffee.

The analysis did not identify an optimal coffee intake, Dr. Simon said. Compared with not drinking coffee, she continued, drinking instant coffee was associated with a lower risk for all-cause mortality, but not CVD mortality or stroke.

Drinking filtered coffee was associated with lower risks for all three outcomes, but there was no significant difference in risk for MI. Drinking decaffeinated coffee was associated with a lower risk for all-cause and CVD mortality.

“Decaffeinated coffee contains a small amount of caffeine,” Dr. Simon pointed out. “Something other than caffeine might have this protective impact,” she suggested.

The researchers and Dr. Lichtenstein declared having no relevant financial disclosures.

New data on using the nonsteroidal mineralocorticoid receptor antagonist (MRA) finerenone to treat patients with type 2 diabetes and chronic kidney disease did more than further confirm this new drug’s efficacy in these patients for slowing progression to end-stage renal disease and reducing hospitalizations for heart failure.

It also strengthened the case for clinicians to be much more proactive in collecting urine specimens from patients with type 2 diabetes (T2D) to find those with albuminuria whose kidney function has not yet dropped below 60 mL/min per 1.73 m², a population that the data show finerenone can help.

The FIDELITY prespecified meta-analysis combined data from two related pivotal trials of finerenone (Kerendia) in a total of more than 13,000 patients with T2D and chronic kidney disease (CKD). Each of these two trials, FIDELIO-DKD and FIGARO-DKD, identified patients with CKD by either of two methods, or a total of four different criteria.

In sum, the two trials enrolled patients with an estimated glomerular filtration rate (eGFR) of 25-90 mL/min per 1.73 m² and a urinary albumin-to-creatinine ratio (UACR) of 30-299, or an eGFR of 25-75 mL/min per 1.73 m² and a UACR of 300-5,000. The result was that 40% of enrolled patients had an eGFR of at least 60, levels that are considered normal, but they also had some level of albuminuria that defined them as having CKD.

The results showed that during a median follow-up of 36 months, patients with a normal eGFR and albuminuria had their combined incidence of cardiovascular disease events (cardiovascular death, MI, stroke, or hospitalization for heart failure) reduced by roughly the same amount as seen in patients with lower levels of eGFR and renal function, a finding that reimagines how clinicians need to routinely screen patients with T2D for CKD, Gerasimos Filippatos, MD, reported at the virtual annual congress of the European Society of Cardiology.

“Measuring UACR in patients with type 2 diabetes is important to identify patients who will benefit from finerenone treatment independent of their eGFR,” said Dr. Filippatos, professor of medicine at the University of Athens and director of the heart failure unit at Attikon University Hospital in Athens.

The combined FIDELITY analysis showed a significant overall cut in the combined cardiovascular disease endpoint of 14% relative to placebo, which reflected a 1.7% absolute reduction in events between the two arms during 3 years of treatment. The primary driver of this benefit was the significant drop in hospitalizations for heart failure on finerenone compared with placebo, which fell by a relative 22% and by an absolute 1.1%, Dr. Filippatos reported.

Routinely screening for albuminuria is ‘practice changing’

“This is really practice changing information for cardiologists,” said Rajiv L. Agarwal, MD, a copresenter of the FIDELITY analysis and a lead investigator of the two finerenone trials.

When cardiologists and possibly other specialists see patients with T2D, they traditionally have focused on measuring left ventricular ejection fraction and checking for other indications of heart failure. The new results from FIDELIO-DKD and FIGARO-DKD showed that finerenone treatment can prevent heart failure onset or worsening in patients with T2D with finerenone, which clinicians can accomplish by “simply measuring UACR,” as well as eGFR, and then treating patients with abnormal levels of either, explained Dr. Agarwal, a nephrologist and professor of medicine at Indiana University in Indianapolis.

“Diabetologists know that when they see patients with diabetes they need to collect a urine sample to check for albuminuria. But when some other clinicians see a patient with type 2 diabetes and a normal eGFR, they often think that the patient is okay and don’t get a urine specimen,” noted Bertram Pitt, MD, another collaborator of the finerenone trials and a heart failure specialist affiliated with the University of Michigan in Ann Arbor.

“We need to pay more attention to UACR and albuminuria; traditionally clinicians have mostly looked at eGFR,” agreed Dipti Itchhaporia, MD, a cardiologist at the Carlton Heart and Vascular Institute of Hoag Hospital in Newport Beach, Calif. UACR “is a marker that should be shared” between endocrinologists, nephrologists, and cardiologists as they together care for patients with T2D, suggested Dr. Itchhaporia, president of the American College of Cardiology.
 

Two pivotal trials with consistent findings

The FIDELITY analysis combined data from the FIDELIO-DKD trial, reported in 2020, and from the FIGARO-DKD trial that was first reported during the current congress as well as in a simultaneous report published online.

Results from the two trials were very consistent, although the primary endpoint in FIDELIO-DKD was a composite measure of renal disease with the combined cardiovascular disease metric a secondary endpoint, while this got flipped in FIGARO-DKD which had the cardiovascular disease composite as its primary endpoint as the combined renal outcomes as a secondary endpoint.

In addition to showing a consistent, significant reduction in both combined cardiovascular disease events and in the specific endpoint of hospitalization for heart failure, the two trials also showed a consistent benefit for slowing renal disease progression, including significantly fewer patients developing end-stage kidney disease. In the combined FIDELITY analysis, treatment with finerenone cut the incidence of end-stage kidney disease by a significant 20% compared with placebo, and by an absolute reduction of 0.6%.

Another common finding was a relatively low incidence of hyperkalemia compared with what’s usually seen using a steroidal MRA, spironolactone or eplerenone. In the combined analysis treatment with finerenone produced a 14% incidence of any hyperkalemia compared with 7% among placebo-treated patients, and the rate of patients stopping their treatment because of hyperkalemia was 1.7% on finerenone and 0.6% on placebo.

“Finerenone is much better tolerated” than the steroidal MRAs in causing clinically significant hyperkalemia, noted Dr. Pitt. “There are a lot of misconceptions” about the potassium-raising potential of MRAs, and “people get frightened” by the potential. Spreading the message of finerenone’s relative safety “will take a lot of education,” he acknowledged. Routine monitoring of potassium levels is a key step to minimizing the risk for hyperkalemia when using finerenone, he added.
 

Suggested benefit from combination treatment

Another intriguing observation from FIDELITY derived from the fact that roughly 7% of enrolled patients were also on treatment with a sodium-glucose cotransporter 2 (SGLT2) inhibitor at entry, and about 7% were on treatment with a glucagon-like peptide-1 (GLP-1) receptor agonist, and in both subgroups the incidence of the composite cardiovascular disease endpoint appeared to suggest additive effects of agents from either of these classes when combined with finerenone. Although the numbers of patients on combined treatment were too low to show a definitive result, “our expectation is that we will see an additive effect,” said Dr. Pitt. Ideally, patients with T2D and CKD “should be on both” an SGLT2 inhibitor and finerenone, he predicted.

SGLT2 inhibitors have now been embraced as a key treatment for patients with T2D or with heart failure with reduced ejection fraction, and the preliminary data suggest that combining these agents with finerenone can provide additional benefit, agreed Dr. Itchhaporia. Aside from the need for more evidence to prove this, there are also practical considerations of “How do we pay for all these fantastic therapies?” She expressed optimism that cost-benefit analyses will eventually show that the additive benefits justify the added cost.

Based largely on results from FIDELIO-DKD, finerenone received marketing approval from the Food and Drug Administration in July 2021 for the indication of treating patients with T2D and chronic kidney disease.

FIGARO-DKD, FIDELIO-DKD, and FIDELITY were sponsored by Bayer, the company that markets finerenone. Dr. Filippatos has received lecture fees from Bayer, and has had financial relationships with Amgen, Boehringer Ingelheim, Medtronic, Novartis, Servier, and Vifor.

Dapagliflozin might reduce the risk for ventricular arrhythmias and sudden death in patients with heart failure and reduced ejection fraction (HFrEF), a post hoc analysis of the DAPA-HF trial suggests.

The addition of dapagliflozin to standard therapy reduced the relative risk for the primary composite endpoint of any serious ventricular arrhythmia, resuscitated cardiac arrest, or sudden death by 21%, compared with placebo (hazard ratio, 0.79; 95% confidence interval, 0.63-0.99). The absolute risk reduction was 1.5% (5.9% vs. 7.4%).

The benefit was consistent in a competing-risks analysis that included all-cause mortality (HR, 0.80; P = .043) and across the individual components of the composite outcome, James Curtain, MD, Cardiovascular Research Centre of Glasgow, said at the annual congress of the European Society of Cardiology.

As previously reported from the main trial, treatment with the sodium-glucose cotransporter 2 (SGLT2) inhibitor cut the primary endpoint of cardiovascular death or worsening heart failure by 26% among 4,744 patients with HFrEF and in New York Heart Association functional class 2-4.

Cochair of the late-breaking science session, Lars Lund, MD, Karolinska Institute, Stockholm, pointed out that dapagliflozin reduced sudden cardiac deaths and related events to an extent similar to that observed for cardiovascular deaths, total mortality, and the main trial’s primary endpoint.

“So does that mean it has any particular effect on arrhythmic events or does it mean, such as a beta-blocker, for example, [it] reduces calcium transience and improves handling of calcium, or does it have an effect simply by improving heart failure?” he asked.

Dr. Curtain replied they are still trying to understand the effects of this new class of drug but that studies have shown dapagliflozin and other SGLT2 inhibitors have favorable effects on adverse cardiac remodeling, which contributes to sudden death and ventricular arrhythmia. They’ve also been shown to reduce cardiac chamber size, left ventricular hypertrophy, and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels over time, consistent with a reduction in myocardial wall stress. “So it could indeed be one of several mechanisms by which they may exert a beneficial cardiac effect.”

Speaking with this news organization, Dr. Curtain pointed out that the Kaplan-Meier curves for the composite outcome began to separate early on, but that the clearest separation was after 9 months, suggestive of a positive action on adverse cardiac remodeling over time.

“This would improve the patients’ heart failure situation, but also thick ventricles are a key risk factor for the occurrence of sudden death and ventricular arrhythmias,” he said. “The effects on adverse cardiac remodeling, given its plausibility in terms of our Kaplan-Meier curves, are one [mechanism] that I’d look to in the first instance, but I’m sure there are more than one actions at play.”

According to the new analysis, the primary outcome occurred in 315 (6.6%) patients; there were 203 adjudicated sudden deaths (64%), 104 investigator-reported ventricular arrhythmias (33%), and 8 resuscitated cardiac arrests (3%). Independent predictors of the primary outcome were higher NT-proBNP levels (odds ratio, 1.54), previous ventricular arrhythmia (OR, 1.93), previous myocardial infarction (OR, 1.42), male sex (OR, 1.53), and higher body mass index (OR, 1.03).

“This would improve the patients’ heart failure situation, but also thick ventricles are a key risk factor for the occurrence of sudden death and ventricular arrhythmias,” he said. “The effects on adverse cardiac remodeling, given its plausibility in terms of our Kaplan-Meier curves, are one [mechanism] that I’d look to in the first instance, but I’m sure there are more than one actions at play.”

According to the new analysis, the primary outcome occurred in 315 (6.6%) patients; there were 203 adjudicated sudden deaths (64%), 104 investigator-reported ventricular arrhythmias (33%), and 8 resuscitated cardiac arrests (3%). Independent predictors of the primary outcome were higher NT-proBNP levels (odds ratio, 1.54), previous ventricular arrhythmia (OR, 1.93), previous myocardial infarction (OR, 1.42), male sex (OR, 1.53), and higher body mass index (OR, 1.03).

As politicians battle over masks and mandates, heated rhetoric has been used to describe the fourth heartbreaking surge in COVID as a “pandemic of the unvaccinated.”

While it may serve to further divide red and blue states, I disagree with the assertion that the current surge in cases is driven simply by the unvaccinated. Why? First, the premise would assume complete efficacy with our vaccinated population, which is statistically incorrect (at least 15 million of the U.S. population never completed a second round of injections), which means they were not considered “fully vaccinated.”

Alternately, we need to examine what has occurred in nations with significantly higher vaccination rates than ours (the United Kingdom and Israel) to realize that variants have overrun the dramatic success achieved in those countries as well. Israel, once considered to be the most vaccinated country in the world, is facing a brutal fourth wave of COVID that has sent the country spiraling into another heartbreaking lockdown.

The unvaccinated could hardly be blamed for what is happening in either of these highly vaccinated countries.
 

The concept of blame

So why use blame? It defeats the purpose of encouraging those who are hesitant or possibly misinformed or disenfranchised to move forward. It lacks compassion. It does not encompass the art and science of nursing (for example, the University of Southern Indiana), such as those that hospitals have used to frame optimal nursing care. I abhor the idea of labeling because it denies the prospect of future comprehension.

Labeling reminds me of one of the saddest cases in my career.
 

An unfortunate case

I was the nurse caring for a man from a motor vehicular accident where an entire family was brutally killed. My patient was alleged to be the cause, with a blood alcohol level of 0.40%+ post hydration, intubated and ventilated, with a flailed chest and multiple orthopedic injuries as well as blunt head trauma. He was secured to the bed with handcuffs, although that was unnecessary. Multiple times I was asked how I could possibly care for such an individual, by the police and even a few colleagues. But it was not my place to judge the man.

He was in pain, and he was dying. I comforted him for the 2 weeks it took his battered body to pass into the next realm. No one visited him except the police, eagerly waiting for the man to wake up to explain the tragic events that occurred. It was my job to ease what pain I could and protect him from labels. Did he deserve the labels? Who knew? I did not care. I cared about his writhing and his physical anguish.
 

The comparison

Blame did not help the situation then, nor does it help us move forward now. As nurses, we seek to work within a framework of understanding. As we tire of caring for thousands of COVID patients, we do not stop to ask if they “deserve” care or if they have taken precautions and lived reasonably prior to seeking assistance for disease. We would not be nurses if we did this.

Think about Gov. Greg Abbott, who has asked that Texans not be allowed to mandate masks for children returning to school. He has recently been diagnosed with COVID, despite assuring the public he is fully vaccinated. Politically, his diagnosis could be visualized as a fiasco for a purple state where he has been adamant in denying the efficacy of masks for children.

Yet, his diagnosis should not be fodder for the press. The first concern should be his health and well-being, similar for any man of his age and potential comorbidity.
 

Conclusion

We should be people first, human beings that remain interconnected by our need for care and survival, not conservatives, independents, or liberals, not “vaccinated or unvaccinated,” not seen as “breakthrough” infections, or the immunosuppressed possibly unable to mount a robust response to COVID.

Labels do not define the ability to effectively defeat coronavirus or variants, as highly vaccinated countries have demonstrated in recent months. We are in the midst of a global pandemic, and the battle is raging onward.

In fact, the longer this pandemic continues, the more likely it is we will need to live with this as an endemic disease, so we should stop blaming those who become ill and need support.

It could be any of us.

Updated August 30, 2021

The SGLT2 inhibitor empagliflozin achieved in EMPEROR-Preserved what no other agent could previously do: unequivocally cut the incidence of cardiovascular death or hospitalization in patients with heart failure and preserved ejection fraction (HFpEF).

MDedge News

Treatment with empagliflozin (Jardiance) led to a significant 21% relative reduction in the rate of cardiovascular death or hospitalization for heart failure (HHF), compared with placebo, among 5,988 randomized patients with HFpEF during a median 26 months of follow-up, proving that patients with HFpEF finally have a treatment that gives them clinically meaningful benefit, and paving the way to an abrupt change in management of these patients, experts said.

“This is the first trial to show unequivocal benefits of any drug on major heart failure outcomes in patients with HFpEF,” Stefan D. Anker, MD, PhD, declared at the virtual annual congress of the European Society of Cardiology.

The 21% relative reduction, which reflected a cut in the absolute rate of the trial’s primary composite endpoint of 3.3% compared with placebo, was driven mainly by a significant 27% relative reduction in the incidence of HHF (P < .001). Empagliflozin treatment, on top of standard therapy for patients with HFpEF, also resulted in a nonsignificant 9% relative risk reduction in the incidence of cardiovascular death, but it had no discernible impact on the rate of death from any cause, said Dr. Anker, professor of cardiology at Charité Medical University in Berlin.

Concurrently with his talk at the meeting, the results were published online in the New England Journal of Medicine.
 

Practice will change ‘quickly’

“This will definitely change our practice, and quite quickly,” said Carlos Aguiar, MD, chair of the Advanced Heart Failure and Heart Transplantation Unit at Hospital Santa Cruz in Carnaxide, Portugal, who was not involved in the study.

Transition to routine use of empagliflozin in patients with HFpEF should be swift because it has already become a mainstay of treatment for patients with heart failure with reduced ejection fraction (HFrEF) based on evidence for empagliflozin in EMPEROR-Reduced. A second sodium-glucose cotransporter 2 (SGLT2 ) inhibitor, dapagliflozin (Farxiga), is also an option for treating HFrEF based on results in the DAPA-HF trial, and the DELIVER trial, still in progress, is testing dapagliflozin as a HFpEF treatment in about 6,000 patients, with results expected in 2022.

About half of the patients in EMPEROR-Preserved had diabetes, and the treatment effects on HFpEF were similar regardless of patients’ diabetes status. Empagliflozin, like other members of the SGLT2 inhibitor class, boosts urinary excretion of glucose and received initial regulatory approval as an agent for glycemic control in patients with type 2 diabetes. Empagliflozin also has U.S.-approved marketing indications for treating patients with HFrEF whether or not they also have diabetes, and for reducing cardiovascular death in patients with type 2 diabetes and cardiovascular disease.

“We already use this drug class in cardiovascular medicine and to treat patients with type 2 diabetes, and we have been eager to find a treatment for patients with HFpEF. This is something that will be really significant,” said Dr. Aguiar.

Heart failure clinicians have “become familiar prescribing” SGLT2 inhibitors following approval of HFrEF indications for some of these agents, noted Mary Norine Walsh, MD, a heart failure specialist with Ascension Medical Group in Indianapolis. The new results “are good news because there have been so few options” for patients with HFpEF, she said in an interview.

EMPEROR-Preserved “is the first phase 3 clinical trial that exclusively enrolled patients with heart failure and an ejection fraction of more than 40% to meet its primary outcome,” and the results “represent a major win against a medical condition that had previously proven formidable,” Mark H. Drazner, MD, said in an editorial that accompanied the published results.

The trial’s findings “should contribute to a change in clinical practice given the paucity of therapeutic options available for patients with HFpEF,” wrote Dr. Drazner, a heart failure specialist who is professor and clinical chief of cardiology at UT Southwestern Medical Center in Dallas.

Theresa A, McDonagh, MD, MBChB, who chaired the panel that just released revised guidelines from the European Society of Cardiology for managing patients with heart failure, predicted that empagliflozin treatment for patients with HFpEF will soon show up in guidelines. It will likely receive a “should be considered” ranking despite being a single study because of the impressive size of the treatment effect and lack of well-supported alternative treatments, she commented as a discussant of the trial during its presentation at the congress. If the DELIVER trial with dapagliflozin shows a similar effect, the recommendation would likely become even stronger, added Dr. McDonagh, a heart failure specialist and professor of cardiology at King’s College, London.

More women enrolled than ever before

EMPEROR-Preserved enrolled adults with chronic HFpEF in New York Heart Association functional class II-IV and a left ventricular ejection fraction greater than 40% starting in 2017 at more than 600 sites in more than 20 countries worldwide including the United States. As background therapy, more than 80% of patients received treatment with either an ACE inhibitor or angiotensin receptor blocker (in some instances in the form of sacubitril/valsartan), more than 80% were on a beta-blocker, and about a third were taking a mineralocorticoid receptor antagonist, making them “very well treated HFpEF patients,” Dr. Anker said.

One of the most notable features of enrollment was that 45% of participants were women, giving this trial the highest inclusion of women compared with all prior studies in patients with HFpEF or with HFrEF, said Dr. Walsh. “HFpEF is very prevalent in woman,” she noted, and having this high participation rate of women in the study increases its relevance to these patients. “It’s important to be able to tell women that patients like you were in the study so we can more easily apply the lessons from the trial to you. That can’t be stressed enough,” she said.

The primary outcome occurred in 415 (13.8%) of the 2,997 patients in the empagliflozin group and in 511 (17.1%) of 2,991 patients who received placebo (hazard ratio, 0.79; 95% confidence interval, 0.69-0.90; P < .001).

The study showed a safety profile consistent with prior experience with empagliflozin, Dr. Anker added.

Pooling EMPEROR-Preserved with EMPEROR-Reduced

The investigators who ran EMPEROR-Preserved designed the trial to closely parallel the EMPEROR-Reduced trial in patients with HFrEF, and they included a prespecified analysis (EMPEROR-Pooled) that combined the more than 9,700 patients in the two studies. This showed a consistent and robust benefit from empagliflozin for reducing HHF across a wide spectrum of patients with heart failure, ranging from patients with left ventricular ejection fractions of less than 25% to patients with ejection fractions as high as 64%. However, the analysis also showed that patients with ejection fractions of 65% or greater received no discernible benefit from empagliflozin, Milton Packer, MD, reported in a separate talk at the congress.

MDedge News

“The findings demonstrate the benefits of empagliflozin across a broad range of patients with heart failure who have ejection fractions of less than 60%-65%,” said Dr. Packer, a researcher at Baylor University Medical Center in Dallas.

This apparent attenuation of an effect at higher ejection fractions “has been observed in other HFpEF trials, most recently in the PARAGON-HF trial” of sacubitril/valsartan (Entresto), he noted. Additional analyses led by Dr. Packer showed that in patients with ejection fractions below 65% the HHF benefit from empagliflozin consistently surpassed the benefit seen with sacubitril/valsartan in PARAGON-HF. But he recommended using both drugs in patients with HFpEF and an ejection fraction up to about 60%.

“If I had a patient with HFpEF I would use both drugs as well as beta-blockers and mineralocorticoid receptor antagonists,” he said during a press briefing.

Another finding from analysis of the EMPEROR-Reduced and EMPEROR-Preserved trials together was that patients with reduced ejection fractions showed a significant 49% relative reduction in the incidence of serious renal outcomes, but this effect was completely blunted in EMPEROR-Preserved.

“Ejection fraction influences the effects of empagliflozin on major renal outcomes,” concluded Dr. Packer in a report on this analysis published simultaneously with the main EMPEROR-Preserved findings (N Engl J Med. 2021 Aug 27. doi: 10.1056/NEJMc2112411). “These data from the EMPEROR trials are unique. We have no comparable data” from any of the other reported studies of SGLT2 inhibitors,” he said.

EMPEROR-Preserved was sponsored by Boehringer Ingelheim and by Eli Lilly, the two companies that jointly market empagliflozin (Jardiance). Dr. Anker has received personal fees from Boehringer Ingelheim and from several other companies, and he has received grants and personal fees from Abbott Vascular and Vifor. Dr. Packer has received consulting fees from Boehringer Ingelheim and from numerous other companies. Dr. McDonagh has has recent financial relationships with AstraZeneca, Cprpus, Novartis, Pfizer, and Vifor. Dr. Aguiar and Dr. Walsh had no disclosures.

Transition to routine use of empagliflozin in patients with HFpEF should be swift because it has already become a mainstay of treatment for patients with heart failure with reduced ejection fraction (HFrEF) based on evidence for empagliflozin in EMPEROR-Reduced. A second sodium-glucose cotransporter 2 (SGLT2 ) inhibitor, dapagliflozin (Farxiga), is also an option for treating HFrEF based on results in the DAPA-HF trial, and the DELIVER trial, still in progress, is testing dapagliflozin as a HFpEF treatment in about 6,000 patients, with results expected in 2022.

About half of the patients in EMPEROR-Preserved had diabetes, and the treatment effects on HFpEF were similar regardless of patients’ diabetes status. Empagliflozin, like other members of the SGLT2 inhibitor class, boosts urinary excretion of glucose and received initial regulatory approval as an agent for glycemic control in patients with type 2 diabetes. Empagliflozin also has U.S.-approved marketing indications for treating patients with HFrEF whether or not they also have diabetes, and for reducing cardiovascular death in patients with type 2 diabetes and cardiovascular disease.

“We already use this drug class in cardiovascular medicine and to treat patients with type 2 diabetes, and we have been eager to find a treatment for patients with HFpEF. This is something that will be really significant,” said Dr. Aguiar.

Heart failure clinicians have “become familiar prescribing” SGLT2 inhibitors following approval of HFrEF indications for some of these agents, noted Mary Norine Walsh, MD, a heart failure specialist with Ascension Medical Group in Indianapolis. The new results “are good news because there have been so few options” for patients with HFpEF, she said in an interview.

EMPEROR-Preserved “is the first phase 3 clinical trial that exclusively enrolled patients with heart failure and an ejection fraction of more than 40% to meet its primary outcome,” and the results “represent a major win against a medical condition that had previously proven formidable,” Mark H. Drazner, MD, said in an editorial that accompanied the published results.

The trial’s findings “should contribute to a change in clinical practice given the paucity of therapeutic options available for patients with HFpEF,” wrote Dr. Drazner, a heart failure specialist who is professor and clinical chief of cardiology at UT Southwestern Medical Center in Dallas.

Theresa A, McDonagh, MD, MBChB, who chaired the panel that just released revised guidelines from the European Society of Cardiology for managing patients with heart failure, predicted that empagliflozin treatment for patients with HFpEF will soon show up in guidelines. It will likely receive a “should be considered” ranking despite being a single study because of the impressive size of the treatment effect and lack of well-supported alternative treatments, she commented as a discussant of the trial during its presentation at the congress. If the DELIVER trial with dapagliflozin shows a similar effect, the recommendation would likely become even stronger, added Dr. McDonagh, a heart failure specialist and professor of cardiology at King’s College, London.

More women enrolled than ever before

EMPEROR-Preserved enrolled adults with chronic HFpEF in New York Heart Association functional class II-IV and a left ventricular ejection fraction greater than 40% starting in 2017 at more than 600 sites in more than 20 countries worldwide including the United States. As background therapy, more than 80% of patients received treatment with either an ACE inhibitor or angiotensin receptor blocker (in some instances in the form of sacubitril/valsartan), more than 80% were on a beta-blocker, and about a third were taking a mineralocorticoid receptor antagonist, making them “very well treated HFpEF patients,” Dr. Anker said.

One of the most notable features of enrollment was that 45% of participants were women, giving this trial the highest inclusion of women compared with all prior studies in patients with HFpEF or with HFrEF, said Dr. Walsh. “HFpEF is very prevalent in woman,” she noted, and having this high participation rate of women in the study increases its relevance to these patients. “It’s important to be able to tell women that patients like you were in the study so we can more easily apply the lessons from the trial to you. That can’t be stressed enough,” she said.

The primary outcome occurred in 415 (13.8%) of the 2,997 patients in the empagliflozin group and in 511 (17.1%) of 2,991 patients who received placebo (hazard ratio, 0.79; 95% confidence interval, 0.69-0.90; P < .001).

The study showed a safety profile consistent with prior experience with empagliflozin, Dr. Anker added.

Pooling EMPEROR-Preserved with EMPEROR-Reduced

The investigators who ran EMPEROR-Preserved designed the trial to closely parallel the EMPEROR-Reduced trial in patients with HFrEF, and they included a prespecified analysis (EMPEROR-Pooled) that combined the more than 9,700 patients in the two studies. This showed a consistent and robust benefit from empagliflozin for reducing HHF across a wide spectrum of patients with heart failure, ranging from patients with left ventricular ejection fractions of less than 25% to patients with ejection fractions as high as 64%. However, the analysis also showed that patients with ejection fractions of 65% or greater received no discernible benefit from empagliflozin, Milton Packer, MD, reported in a separate talk at the congress.

MDedge News

“The findings demonstrate the benefits of empagliflozin across a broad range of patients with heart failure who have ejection fractions of less than 60%-65%,” said Dr. Packer, a researcher at Baylor University Medical Center in Dallas.

This apparent attenuation of an effect at higher ejection fractions “has been observed in other HFpEF trials, most recently in the PARAGON-HF trial” of sacubitril/valsartan (Entresto), he noted. Additional analyses led by Dr. Packer showed that in patients with ejection fractions below 65% the HHF benefit from empagliflozin consistently surpassed the benefit seen with sacubitril/valsartan in PARAGON-HF. But he recommended using both drugs in patients with HFpEF and an ejection fraction up to about 60%.

“If I had a patient with HFpEF I would use both drugs as well as beta-blockers and mineralocorticoid receptor antagonists,” he said during a press briefing.

Another finding from analysis of the EMPEROR-Reduced and EMPEROR-Preserved trials together was that patients with reduced ejection fractions showed a significant 49% relative reduction in the incidence of serious renal outcomes, but this effect was completely blunted in EMPEROR-Preserved.

“Ejection fraction influences the effects of empagliflozin on major renal outcomes,” concluded Dr. Packer in a report on this analysis published simultaneously with the main EMPEROR-Preserved findings (N Engl J Med. 2021 Aug 27. doi: 10.1056/NEJMc2112411). “These data from the EMPEROR trials are unique. We have no comparable data” from any of the other reported studies of SGLT2 inhibitors,” he said.

EMPEROR-Preserved was sponsored by Boehringer Ingelheim and by Eli Lilly, the two companies that jointly market empagliflozin (Jardiance). Dr. Anker has received personal fees from Boehringer Ingelheim and from several other companies, and he has received grants and personal fees from Abbott Vascular and Vifor. Dr. Packer has received consulting fees from Boehringer Ingelheim and from numerous other companies. Dr. McDonagh has has recent financial relationships with AstraZeneca, Cprpus, Novartis, Pfizer, and Vifor. Dr. Aguiar and Dr. Walsh had no disclosures.

The Food and Drug Administration has approved difelikefalin for treatment of moderate to severe pruritus associated with chronic kidney disease in adults undergoing hemodialysis, the first agent approved from a novel class of kappa opioid receptor agonists.

Some nephrologists welcomed the Aug. 23 approval of this new option for treating pruritus, a relatively common and often hard-to-resolve complication of dialysis in patients with chronic kidney disease (CKD) that can substantially impinge on quality of life for some patients, but also voiced uncertainty about the role of a new agent with a modest trial track record that may be expensive and face insurance-coverage hurdles.

“Uptake of difelikefalin will depend on awareness of itch among patients dependent on hemodialysis, and on payment policies,” predicted Daniel E. Weiner, MD, a nephrologist at Tufts Medical Center in Boston. “Pruritus is underdiagnosed among people with kidney failure, and in some patients ongoing pruritus can be highly impactful on sleep and quality of life. The clinical trial results were very encouraging that difelikefalin is effective and safe,” which makes recognition of pruritus as a significant issue for patients a key factor in uptake of the new drug, Dr. Weiner, an investigator in a difelikefalin clinical study, said in an interview.

Other nephrologists acknowledged the substantial problem that itch can pose for many patients with CKD on dialysis but questioned the weight of evidence behind difelikefalin’s approval.
 

Two pivotal trials with fewer than 900 total randomized patients

The data considered by the FDA primarily featured results from two pivotal trials, KALM-1 and KALM-2. KALM-1 randomized 378 patients with CKD and on hemodialysis and with moderate to severe pruritus to intravenous treatment with difelikefalin or placebo three times a week for 12 weeks with a primary endpoint of an improvement (decrease) of at least 3 points from baseline in their Worst Itching Intensity Numerical Rating Scale (WI-NRS) score, which averaged just over 7 points at baseline. After 12 weeks on treatment, 52% of patients who received difelikefalin had at least a 3-point drop, compared with 31% of patients who received placebo, a significant difference. The results appeared in a 2020 report in the New England Journal of Medicine.

Confirmatory results came in the second pivotal trial, KALM-2, a similarly designed, 12-week study that randomized 473 patients, with 54% of those in the active arm achieving at least a 3-point cut in their baseline WI-NRS score, compared with 42% of patients who received placebo, a significant difference. A report at the Kidney Week meeting sponsored by the National Kidney Foundation in October 2020 presented the KALM-2 results, but the findings have not yet appeared in a published article.

In sum, the data suggest that treatment with difelikefalin will, on average, produce a clinically meaningful effect on itch compared with placebo in about 20% of patients, with nearly half the patients who receive the active drug having a less robust response and many patients who receive no active treatment also show a meaningful cut in their pruritus severity in a trial setting, noted Paul Palevsky, MD, professor of medicine at the University of Pittsburgh and chief of the renal section at the Veterans Affairs Pittsburgh Healthcare System.

The upshot is that questions linger over which patients are the best candidates for this drug and how it might perform in real-world practice given difelikefalin’s limited track record, Dr. Palevsky said in an interview.

In addition, the labeling specifies the indication is for patients with moderate to severe pruritus, but itching severity is not routinely quantified in these patients in current practice, added Dr. Palevsky, who is also president of the National Kidney Foundation.

Dr. Weiner noted that another unknown is the appropriate duration of treatment in real-world use.
 

What will it cost, and will it be covered?

The drug’s price and insurance coverage will likely be a major factor in uptake of the new drug, agreed both Dr. Weiner and Dr. Palevsky, especially the coverage decision for Medicare patients by the Centers for Medicare & Medicaid Services. A corollary is whether or not coverage for difelikefalin, which patients receive as an intravenous infusion during each of their usual three-times-a-week dialysis sessions, will lie outside of the bundled dialysis reimbursement payment. If is no mechanism exists to pay for difelikefalin separately beyond the current bundled dialysis rate, “I suspect it will not get used very much unless it is very inexpensive,” predicted Dr. Weiner.

Another issue is where difelikefalin fits within the lineup of standard treatment options. “A lot of people receiving hemodialysis suffer from pruritus and have not been successfully treated. For these individuals difelikefalin could be a game changer,” Dr. Weiner said.

Other nephrologists have a more positive take on the existing treatment options.

“Start systemic therapy for patients with itch that is significantly affecting quality of life; stepping up from topical therapy just delays effective treatment,” advised Hugh C. Rayner, MD, a nephrologist affiliated with Birmingham (England) Heartland’s Hospital who was lead author on a review of pruritus treatments for patients with CKD on hemodialysis.

“Standard systemic therapy is gabapentin or pregabalin,” an approach “supported by robust evidence confirmed in a Cochrane review,” he said in an interview. The impact of difelikefalin “will be limited as its effectiveness in reducing itch is modest at best and far inferior to gabapentin and pregabalin,” Dr. Rayner added. Difelikefalin’s “main downsides will be its cost, compared with gabapentin, and its gastrointestinal side effects.”
 

Adverse-event profiles

In KALM-1, the most frequent adverse effects from difelikefalin treatment was diarrhea, in 10% of patients, compared with a 4% rate among patients who received placebo. Vomiting occurred at a 5% incidence on difelikefalin and in 3% of patients on placebo. All serious adverse events occurred in 26% of patients on difelikefalin and in 22% of those who received placebo. Discontinuations because of an adverse event occurred in 8% of patients on difelikefalin and in 5% of the placebo patients.

An editorial that accompanied the published KALM-1 report in 2020 said “the findings are compelling, although diarrhea, dizziness, and vomiting were frequent side effects.”

Both Dr. Weiner and Dr. Palevsky were more reserved than Dr. Rayner in their appraisal of gabapentin and pregabalin, although Dr. Palevsky admitted that he has prescribed one or the other of these two drugs to “lots of patients,” especially gabapentin. “But they are not completely benign drugs,” he cautioned, a concern echoed by Dr. Weiner.

“Antihistamines, gabapentin, and pregabalin have a high side-effect burden in patients on hemodialysis and limited efficacy, and are poor options for chronic pruritus management,” explained Dr. Weiner. “I would favor difelikefalin to chronic prescription of these other agents” because difelikefalin “appears effective and has a very low side effect burden. Very few effective treatments for pruritus do not have side effects.”

Difelikefalin is a peripherally restricted, selective kappa opioid receptor agonist that exerts antipruritic effects by activating kappa opioid receptors on peripheral neurons and immune cells. The drug’s hydrophilic, small-peptide structure restricts passive diffusion across membranes, which limits the drug’s access to kappa opioid receptors in the central nervous system and hence reduces potential adverse effects.

The FDA made this approval decision without consulting an advisory committee. The companies that will market difelikefalin (Korsuva), Cara Therapeutics and Vifor Pharma, announced that their U.S. promotional launch of the drug starts early in 2022.

The KALM-1 and KALM-2 studies were sponsored by Cara Therapeutics and Vifor Pharma, the two companies that have been jointly developing difelikefalin. Dr. Pavelsky and Dr. Rayner had no relevant disclosures. Dr. Weiner was previously an adviser to Cara and Vifor and participated as an investigator in a difelikefalin clinical study, but more recently has had no relationships with the companies.

In medical school, I remember thinking that telling a patient “you have cancer” would be the most professionally challenging phrase I would ever utter. And don’t get me wrong – it certainly isn’t easy; but, compared with telling someone “you are infertile,” it’s a cakewalk.

Maybe it’s because people “have” cancer and cancer is something you “fight.” Or maybe because, unlike infertility, cancer has become a part of public life (think lapel pins and support groups) and is now easier to accept. On the other hand, someone “is” infertile. The condition is a source of embarrassment for the couple and is often hidden from society.

Here’s another concerning point of contrast: While the overall rate of cancer death has declined since the early 1990s, infertility is increasing. Reports now show that one in six couples have problems conceiving and the use of assisted reproductive technologies is increasing by 5%-10% per year. Many theories exist to explain these trends, chief among them the rise in average maternal age and the increasing incidence of obesity, as well as various other male- and female-specific factors.

But interestingly, recent data suggest that the most male of all male-specific factors – total sperm count – may be specifically to blame.

According to a recent meta-analysis, the average total sperm count in men declined by 59.3% between 1973 and 2011. While these data certainly have limitations – including the exclusion of non-English publications, the reliance on total sperm count and not sperm motility, and the potential bias of those patients willing to give a semen sample – the overall trend nevertheless seems to be clearly downward. What’s more concerning, if you believe the data presented, is that there does not appear to be a leveling off of the downward curve in total sperm count.

Think about that last statement. At the current rate of decline, the average sperm count will be zero in 2045. One of the lead authors on the meta-analysis, Hagai Levine, MD, MPH, goes so far as to state, “We should hope for the best and prepare for the worst.”

As a matter of personal philosophy, I’m not a huge fan of end-of-the-world predictions because they tend not to come true (think Montanism back in the 2nd century; the 2012 Mayan calendar scare; or my personal favorite, the Prophet Hen of Leeds). On the other hand, the overall trend of decreased total sperm count in the English-speaking world seems to be true and it raises the interesting question of why.

According to the Mayo Clinic, causes of decreased sperm count include everything from anatomical factors (like varicoceles and ejaculatory issues) and lifestyle issues (such as recreational drugs, weight gain, and emotional stress) to environmental exposures (heavy metal or radiation). The senior author of the aforementioned meta-analysis, Shanna Swan, PhD, has championed another theory: the widespread exposure to endocrine-disrupting chemicals in everyday plastics.

It turns out that at least two chemicals used in the plastics industry, bisphenol A and phthalates, can mimic the effect of estrogen when ingested into the body. Even low levels of these chemicals in our bodies can lead to health problems.

Consider for a moment the presence of plastics in your life: the plastic wrappings on your food, plastic containers for shampoos and beauty products, and even the coatings of our oral supplements. A study by the Centers for Disease Control and Prevention looked at the urine of people participating in the National Health and Nutrition Examination Survey and found detectable concentrations of both of these chemicals in nearly all participants.

In 2045, I intend to be retired. But in the meantime, I think we all need to be aware of the potential impact that various endocrine-disrupting chemicals could be having on humanity. We need more research. If indeed the connection between endocrine disruptors and decreased sperm count is borne out, changes in our environmental exposure to these chemicals need to be made.

In medical school, I remember thinking that telling a patient “you have cancer” would be the most professionally challenging phrase I would ever utter. And don’t get me wrong – it certainly isn’t easy; but, compared with telling someone “you are infertile,” it’s a cakewalk.

Maybe it’s because people “have” cancer and cancer is something you “fight.” Or maybe because, unlike infertility, cancer has become a part of public life (think lapel pins and support groups) and is now easier to accept. On the other hand, someone “is” infertile. The condition is a source of embarrassment for the couple and is often hidden from society.

Here’s another concerning point of contrast: While the overall rate of cancer death has declined since the early 1990s, infertility is increasing. Reports now show that one in six couples have problems conceiving and the use of assisted reproductive technologies is increasing by 5%-10% per year. Many theories exist to explain these trends, chief among them the rise in average maternal age and the increasing incidence of obesity, as well as various other male- and female-specific factors.

But interestingly, recent data suggest that the most male of all male-specific factors – total sperm count – may be specifically to blame.

According to a recent meta-analysis, the average total sperm count in men declined by 59.3% between 1973 and 2011. While these data certainly have limitations – including the exclusion of non-English publications, the reliance on total sperm count and not sperm motility, and the potential bias of those patients willing to give a semen sample – the overall trend nevertheless seems to be clearly downward. What’s more concerning, if you believe the data presented, is that there does not appear to be a leveling off of the downward curve in total sperm count.

Think about that last statement. At the current rate of decline, the average sperm count will be zero in 2045. One of the lead authors on the meta-analysis, Hagai Levine, MD, MPH, goes so far as to state, “We should hope for the best and prepare for the worst.”

The death ‘dog’

Imagine you’re out in your backyard managing the grill for a big family barbecue. You’ve got a dazzling assortment of meat assorted on your fancy new propane grill, all charring nicely. Naturally, the hot dogs finish first, and as you pull them off, you figure you’ll help yourself to one now. After all, you are the chef, you deserve a reward. But, as you bite into your smoking hot sandwich, a cold, bony finger taps you on the shoulder. You turn and come face to face with the Grim Reaper. “YOU JUST LOST 36 MINUTES,” Death says. “ALSO, MAY I HAVE ONE OF THOSE? THEY LOOK DELICIOUS.”

PxHere

Nonplussed and moving automatically, you scoop up another hot dog and place it in a bun. “WITH KETCHUP PLEASE,” Death says. “I NEVER CARED FOR MUSTARD.”

“I don’t understand,” you say. “Surely I won’t die at a family barbecue.”

“DO NOT CALL ME SHIRLEY,” Death says. “AND YOU WILL NOT. IT’S PART OF MY NEW CONTRACT.”

A new study, published in Nature Food, found that a person may lose up to 36 minutes for every hot dog consumed. Researchers from the University of Michigan analyzed nearly 6,000 different foods using a new nutritional index to quantify their health effects in minutes of healthy life lost or gained. Eating a serving of nuts adds an extra 26 minutes of life. The researchers determined that replacing just 10% of daily caloric intake from beef and processed foods with fruits, vegetables, and nuts can add 48 minutes per day. It would also reduce the daily carbon footprint by 33%.

“So you go around to everyone eating bad food and tell them how much life they’ve lost?” you ask when the Grim Reaper finishes his story. “Sounds like a drag.”

“IT IS. WE’VE HAD TO HIRE NEW BLOOD.” Death chuckles at its own bad pun. “NOW IF YOU’LL EXCUSE ME, I MUST CHASTISE A MAN IN FLORIDA FOR EATING A WELL-DONE STEAK.”
 

More stress, less sex

As the world becomes a more stressful place, the human population could face a 50% drop by the end of the century.

Think of stress as a one-two punch to the libido and human fertility. The more people are stressed out, the less likely they are to have quality interactions with others. Many of us would rather be alone with our wine and cheese to watch our favorite show.

Researchers have found that high stress levels have been known to drop sperm count, ovulation, and sexual activity. Guess what? There has been a 50% decrease in sperm counts over the last 50 years. That’s the second punch. But let’s not forget, the times are changing.

“Changes in reproductive behavior that contribute to the population drop include more young couples choosing to be ‘child-free,’ people having fewer children, and couples waiting longer to start families,” said Alexander Suvorov, PhD, of the University of Massachusetts, the paper’s author.

Let’s summarize: The more stress we’re dealing with, the less people want to deal with each other.

Who would have thought the future would be less fun?

Greetings, ladies and gentlemen! Welcome to the first round of Pandemic Pandemonium. Let’s get right to the action.

This week’s preshow match-off involves face mask woes. The first comes to us from Alabama, where a woman wore a space helmet to a school board meeting to protest mask mandates. The second comes from Australia, in the form of mischievous magpies. We will explain.

It is not uncommon for magpies to attack those who come too close to their nests in the spring, or “swooping season,” as it’s affectionately called. The magpies are smart enough to recognize the faces of people they see regularly and not attack; however, it’s feared that mask wearing will change this.

While you’re chewing on that exciting appetizer, let’s take a look at our main course, which has a distinct governmental flavor. Jeff Landry is the attorney general of Louisiana, and, like our space-helmet wearer, he’s not a fan of mask mandates. According to Business Insider, Mr. Landry “drafted and distributed sample letters intended to help parents evade mask-wearing ordinances and COVID-19 vaccination requirements for their children in schools.”

Up against him is the Food and Drug Administration’s Twitter account. In an unrelated matter, the agency tweeted, “You are not a horse. You are not a cow. Seriously, y’all. Stop it.” This was in response to people using the nonhuman forms of ivermectin to treat very human COVID-19.

Well, there you have it. Who will win tonight’s exciting edition of Pandemic Pandemonium? The first reader to contact us gets to decide the fate of these worthy contestants.
 

From venomous poison to heart drug

It’s not likely that anyone who sees a giant, venomous spider is thinking, “Hey! That thing could save my life!” It’s usually quite the opposite. Honestly, we would run away from just about any spider. But what if one of the deadliest spiders in the world could also save you from dying of a heart attack?

PxHere

You probably don’t believe us, right? That’s fair, but the deadly Fraser Island (K’gari) funnel web spider, might also be the most helpful. Investigators from the University of Queensland in Australia have found a way to extract a molecule from the spider’s venom that might help stop damage from heart attacks and may even preserve hearts being used for transplants. “The Hi1a protein from spider venom blocks acid-sensing ion channels in the heart, so the death message is blocked, cell death is reduced, and we see improved heart cell survival,” Nathan Palpant, PhD, of the university, noted in a written statement.

No one has ever developed a drug to stop the “death signal,” so maybe it’s time to befriend spiders instead of running away from them in horror. Just leave the venom extraction to the professionals.

There will be so much more to the annual congress of the European Society of Cardiology, which begins Aug. 27 with an all-virtual format, than detailed primary results of EMPEROR-Preserved, a trial that could mark a turning point for heart failure (HF) medical therapy.

Also among the featured Hot Line and Late-Breaking Science sessions are – along with many other studies – explorations of arrhythmia management (ablation or guided by loop recorder); secondary prevention, including by vaccination; oral anticoagulation, notably after transcatheter valve procedures; and colchicine or thrombosis prophylaxis in hospitalized patients with COVID-19.

There will even be a head-to-head comparison of two long-familiar left atrial appendage (LAA) occluders, and a population-based, randomized trial of sodium restriction through wide-scale use of a potassium-based salt substitute.

The congress will also introduce four guideline documents at sessions throughout the Congress, one on each day. They cover new and modified recommendations for heart failure; pacing, including cardiac resynchronization therapy (CRT); cardiovascular (CV) disease prevention; and, with cosponsorship from the European Association for Cardio-Thoracic Surgery, valvular heart disease.
 

The virtues of virtual

That next year’s Congress is slated for Aug. 27-30 in Barcelona should be welcome news for anyone whose “what if” curiosity about all-virtual conferences has already been satisfied. But with experience comes wisdom, as the medical societies have learned that online scientific meetings have some winning qualities that may be worth keeping, as least for a while.

“I think there is no doubt that the digital format will continue, for several reasons. One is that this pandemic is not over,” ESC Congress program committee chair Stephan Windecker, MD, Bern (Switzerland) University Hospital, , told this news organization. “As long as it is not over, the digital format is here to stay.”

But it also appears that people who haven’t been able to attend the congress in person are keen to log in and engage online, Dr. Windecker said. The 2020 all-virtual conference drew a much younger pool of registrants, on average, than did the live conferences before the pandemic.

“I think that’s an indication of people that may be in training, in early stages of their career, or they don’t have the support from departments or from their practice, or other financial means.” But they are able to participate via computer, tablet, or smartphone, he said.

“Another advantage is that the recorded content can be replayed at the convenience of whoever wants to consume it at a later point in time,” he added. “Those are just some examples why the digital format is likely to stay,” on its own or in a new age of hybrid meetings.  
 

New and updated guidelines

Leading off the guideline series is the document on diagnosis and treatment of acute and chronic HF, which leveraged the past few busy years of HF clinical trials to arrive at a number of new recommendations and strengthened level-of-evidence ratings. It covers both drug and device therapy of HF with reduced ejection fraction (HFrEF) and acute decompensated HF, and tweaks and further enshrines the concept of HF with mildly reduced ejection fraction (HFmrEF).

Several updated recommendations for both long-used and novel medications, notably the sodium-glucose cotransporter 2 inhibitors, will be included because of the recently appreciated evidence-based impact in HFrEF, Dr. Windecker noted.

“I think it will be particularly interesting to look for the SGLT2 inhibitors as not a completely new class of drugs, but certainly one where there has been a lot of new evidence, to look at how those drugs will be integrated in the overall care pathway.”

A top-line preview of the new HF guideline limited to drug therapy, presented at July’s Heart Failure Association of the European Society of Cardiology (ESC-HFA), provided a simple answer to a common question in the new, bountiful age of HFrEF medications: Which meds, initiated in what order?

As it happens, the new recommendation for first-line HFrEF drug therapy is not a silver bullet, but a shotgun – prompt initiation of at least four meds, one from each of four drug classes: renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRA), and SGLT2 inhibitors. Each class, as described in the document, is to be started as soon as safely feasible, in a sequence deemed appropriate for each individual patient.
 

Spotlight on EMPEROR-Preserved

The world already knows that the trial, which tested the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) on top of standard therapy, “met” its primary endpoint in almost 6,000 patients with HF with preserved ejection fraction (HFpEF), who included some with HFmrEF by more contemporary definitions.

That means patients in EMPEROR-Preserved assigned to take empagliflozin showed significantly fewer events that made up the study’s primary endpoint, a composite of CV death or HF hospitalization. It appears to be the first clearly significant overall medical therapy benefit for a clinical primary endpoint in a major randomized HFpEF drug trial.

And that, pending fuller presentation of trial results at the Congress on Aug. 27, could be a huge deal for the half of HF patients with left ventricular ejection fractions (LVEF) higher than the HFrEF range.

Those early top-line results weren’t a decisive bombshell for a field now filled with hope for a practice-changing empagliflozin outcome in EMPEROR-Preserved, which isn’t a certainty. They were more like the “boom” of a mortar launching a rocket of fireworks that may explode into a chrysanthemum or green comet or, sometimes, turn out to be no more than a dud. The promise of the early cursory results critically depends on further details.

“Provided there is a compelling benefit, this is what everyone has been waiting for in this condition for decades,” Mikhail N. Kosiborod, MD, director of cardiometabolic research at Saint Luke’s Mid-America Heart Institute, Kansas City, Mo., said.

“Already knowing that the trial met the primary endpoint is obviously very intriguing and encouraging,” he added. “But there are things we don’t know, such as: What is the magnitude of benefit? And whether that benefit, whatever the magnitude, is driven by reductions in both heart failure hospitalizations and cardiovascular death, or only one of the two.”

For example: “If we see an impressive benefit for reduction of hospitalizations, but not a significant reduction in death, that would still be a huge advance. That’s because, to date, we don’t have any drug for HFpEF that has convincingly demonstrated a compelling reduction in heart failure hospitalization or improvement in symptoms, function, or quality of life,” observed Dr. Kosiborod, who wasn’t part of EMPEROR-Preserved.

There have been “suggestions” from HFrEF trials that empagliflozin and dapagliflozin (Farxiga, AstraZeneca) “have very comparable effects on at least the endpoint of cardiovascular death or hospitalization for heart failure,” he said. “So, my expectation would be that whatever is observed in EMPEROR-Preserved is likely a class effect, as well.”

Following EMPEROR-Preserved on the agenda is EMPEROR-Pooled, a patient-level combined analysis of the EMPEROR series of trials that spans the range of HF, regardless of ejection fraction or diabetes status, primarily exploring the effects of empagliflozin on renal function.
 

Other offerings, Friday, Aug. 27

Scheduled immediately after EMPEROR-Preserved is a presentation on the SMART-MI trial, which should clarify whether management guided by continuous ambulatory monitoring is effective in patients considered at especially high arrhythmic risk. Entry called for recent myocardial infarction and an LVEF of 36%-50% with evidence of cardiac autonomic dysfunction.

The trial randomly assigned 400 such patients to be or not be implanted with a Reveal LINQ (Medtronic) loop recorder and followed them for up to 18 months, primarily for detection of potentially serious arrhythmic events. Endpoints that involved mortality, hospitalization or other clinical events were secondary.

In a time slot preceding both SMART-MI and EMPEROR-Preserved, the GUIDE-HF trial is following a projected 3,600 patients with HF implanted with a CardioMEMS HF System (Abbott) pulmonary artery (PA) pressure sensor to explore the its value for guiding management.

The trial’s three cohorts, followed for at least 12 months, include randomized sensor-monitored and control groups of patients with New York Heart Association class 2-4 symptoms, as well as a third observational set of patients in NYHA class 3. That’s the indication for which the CardioMEMS monitor gained approval in the United States in 2014 based on the 2011 CHAMPION trial, and which fared just as well in the 2017 CHAMPION Post-Approval Study.

The Friday Hot Lines also include Dal-GenE, which has entered about 6,000 patients with recent MI to test the once-abandoned cholesterol ester transfer protein (CETP) inhibitor dalcetrapib (DalCor) for any secondary-prevention benefits when used selectively. The trial’s hook: All its patients are confirmed to have the AA genotype of the rs1967309 variant in the ADCY9 gene, which has been associated with a pronounced clinical response to CETP inhibition.

Saturday, Aug. 28

The direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists in patients with nonvalvular atrial fibrillation (AFib). But whether DOACs are similarly preferable in the growing world population of people who have undergone transcatheter aortic valve replacement (TAVR or TAVI), an issue explored with variable results in the ATLANTIS and GALILEO trials, is far from settled.

The ENVISAGE-TAVI AF trial explored the question for the factor X inhibitor edoxaban (Savaysa, Lixiana, Daiichi-Sankyo) in 1,400 patients with AFib and a transfemoral TAVR in the previous 5 days, who were randomly assigned to the DOAC or standard management along with discretionary antiplatelet therapy. They’ve been followed for up to 3 years for a composite endpoint of clinical events – including death, MI, and stroke – and for major bleeding.

The day will also feature MASTER DAPT, a comparison of two dual-antiplatelet therapy (DAPT) regimens in an estimated 4,300 patients considered to be high-risk for bleeding who had received the sirolimus-eluting Ultimaster (Terumo) coronary stent, which has a bioresorbable polymer coating.

Investigators have randomly assigned patients to receive either very-short-duration DAPT, for about a month after stenting, followed by a P2Y12 inhibitor alone for up to a year after the procedure; or a more conventional regimen of a P2Y12 inhibitor for 6-12 months with aspirin maintained for a total of 12 months.

Later that day, investigators from the FIGARO-DKD trial will present their results based on 7,437 patients with type 2 diabetes and chronic kidney disease (CKD), a much fuller version than the top-line findings announced by sponsor Bayer 3 months ago.

Those top-line results suggested that patients assigned to receive the nonsteroidal nonselective mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) on top of standard care benefited with a drop in risk for the primary endpoint of CV death or nonfatal CV events.

Finerenone was recently approved in the United States for treating patients with both type 2 diabetes and CKD based on the published FIDELIO-DKD trial, which had seen less CKD progression and fewer CV events in such patients who took the novel MRA.

Although similar in design to FIGARO-DKD, FIDELIO-DKD had entered fewer patients with early-stage diabetic kidney disease (DKD). That led researchers to pool the two trials’ populations to create a cohort that spans the spectrum of DKD severity. An analysis of the pooled cohort, dubbed FIDELITY, is on the schedule after FIGARO-DKD.

After FIDELITY is the prospective APAF-CRT trial that is following a projected 1,830 patients with permanent, symptomatic AFib and a recent hospitalization for AFib or HF and who were not good candidates for standard ablation. They were assigned to receive either atrioventricular junctional ablation followed by CRT, with or without a defibrillation, on top of optimal meds – a so-called “ablate-and-pace” strategy – or an implantable cardioverter defibrillator with rate-control drug therapy.

The new analysis represents the trial’s second phase in which mortality was followed for 4 years as the primary endpoint, in contrast to the previously reported initial phase that followed the first 102 patients for 2 years for the composite primary endpoint of death, worsening HF, and HF hospitalization. The first phase had halted enrollment before reaching its planned target of 280 patients after an interim analysis showed a significant benefit for ablate and pace. 

Next up: DECAAF 2, a randomized assessment of whether catheter ablation for AFib guided by delayed gadolinium enhancement on MRI, a proxy for scar tissue, can be more effective than standard AFib ablation by pulmonary vein isolation alone. An estimated 900 patients with persistent AFib who had never before undergone ablation for the arrhythmia were randomly assigned to one strategy or the other and followed for AFib recurrence over 18 months.
 

Sunday, Aug. 29

The TOMAHAWK trial aimed to clarify the optimal timing of invasive coronary angiography for resuscitated patients with non–ST-segment elevation out-of-hospital cardiac arrest, a broad population in a setting for which there is little randomized-trial guidance. Investigators randomly assigned 558 such patients to undergo immediate invasive angiography or to direct intensive care unit admission for initial standard care with discretionary delayed angiography. Patients were followed for all-cause mortality, with other clinical events and neurologic outcomes as secondary endpoints.

Next on the schedule, the RIPCORD-2 trial randomly assigned 1,100 patients with stable known or suspected coronary artery disease (CAD) to undergo conventional angiography alone or with added direct pressure-wire measurement of fractional flow reserve to guide management decisions. Primary outcomes include health care costs and patient-reported quality of life at 1 year.

Slated for later that day, the Asymptomatic Carotid Surgery Trial-2 (ACST-2) has entered an estimated 3600 patients with a substantial carotid artery narrowing not associated with symptoms but for which either carotid endarterectomy (CEA) or carotid artery stenting (CAS) was considered anatomically feasible. There also must have been “substantial uncertainty” regarding the optimal procedure choice.

The trial, conducted in 40 countries primarily in Europe and North America and launched in 2008, randomly assigned the patients to undergo either CEA or CAS, in both cases with appropriate medical therapy, and followed them for periprocedural events and up to 10 years for strokes and stroke-related events.

The LOOP study, which is to directly follow ACST-2, has explored whether screening for AFib using the Medtronic Reveal LINQ monitor in older patients with non-AFib stroke risk factors – with oral anticoagulation prescribed for those who test positive – can lower their risk for stroke or systemic embolism. It randomly assigned 6,000 such patients to care guided by the loop recorder or to standard care.

On a somewhat larger scale, the Salt Substitute and Stroke Study (SSaSS) randomly assigned a total of 20,996 people in about 600 villages across northern China and Tibet to sodium-restriction intervention and control groups by village. All participants had a history of stroke or were aged at least 60 years with uncontrolled hypertension.

As described by the trial’s online portal, participants in villages assigned to the intervention group were given a supply of a low-sodium, potassium-supplementing salt substitute to replace their own salt supplies, along with education on the health benefits of sodium restriction. Participants in control villages continued their normal diets and, at the trial’s beginning, received “advice to reduce their salt intake.” All were required to own a telephone.

Clinical events, including strokes and hospitalizations throughout a 5-year follow-up, were tracked by phone calls made to all participants every 6 months and were documented at follow-up home visits.

Sunday is also to feature a Late-Breaking Trials session with a focus on COVID-19, which leads off with COLCOVID, a test of colchicine in patients hospitalized for suspected SARS-CoV-2 infection and in acute respiratory distress.

The 1,279 participants in Argentina were randomly assigned to receive or not receive the potent anti-inflammatory agent on top of antivirals and other standard management and followed for death or new need for mechanical ventilation. A successful outcome would contrast with the RECOVERY trial, which terminated a colchicine group of patients hospitalized with COVID-19 because of a lack of efficacy earlier this year.

COLCOVID is to be followed by the MICHELLE trial of rivaroxaban (Xarelto, Bayer/Janssen) prophylaxis, compared with no preventive oral anticoagulant, in 320 patients who, when hospitalized with COVID-19, had been on parenteral anticoagulants because of an elevated risk for venous thromboembolism. The trial, conducted in Brazil, called for postdischarge rivaroxaban at a once-daily dosage of 10 mg for about 1 month.

The session also includes a presentation called “Insights into the Effects of the COVID-19 Pandemic: Comprehensive Analysis from the GUIDE-HF Trial,” the primary outcomes of which will be reported on the first day of the Congress.

Following is a presentation on the PREPARE-IT study of icosapent ethyl (Vascepa, Amarin), given at high dosages intended to be anti-inflammatory, compared with placebo, in an estimated 4,000 adults. The trial has two groups: A prevention group of adults living and circulating in the community; and a treatment group of patients aged at least 40 years with confirmed symptomatic SARS-CoV-2 infection for whom the need for hospitalization isn’t clear.
 

Monday, Aug. 30

The final day of the Congress features a trial called Influenza Vaccination after Myocardial Infarction (IAMI), which has tested the secondary preventive effect of influenza vaccination by randomly assigning 2,571 patients to receive a standard vaccine or a saline placebo injection on one occasion.

Entry to the international trial called for a diagnosis of MI with or without ST-segment elevation, or stable CAD and age at least 75 years with other risk factors. The patients were followed for death, MI, stent thrombosis, and a slew of secondary endpoints over 12 months.

Monday offerings continue later in a time block leading off with the STEP trial, which has randomly assigned an estimated 8,000 patients at 40 centers in China who are 60 to 80 years of age with a systolic blood pressure of 140 to <190 mm Hg to be on standard guideline-based therapy or an intensive drug-management strategy.

The systolic BP goals are 130 to <150 mm Hg for standard care and 110 to <130 mm Hg for the intensive regimen. The composite primary endpoint includes death and clinical events related to acute coronary syndromes, HF, revascularization, and stroke.

Following on heels of STEP, the Amulet IDE trial – the first major randomized comparison of two transcatheter LAA closure devices – entered 1,878 patients with nonvalvular AFib who were considered high-risk for bleeding and stroke or systemic embolism.

They were randomly assigned in the noninferiority trial to receive either the AMPLATZER Amulet (Abbott Medical Devices) or the WATCHMAN (Boston Scientific) closure devices and were followed for safety and efficacy for up to 5 years.

Both LAA closure devices, intended to make patients with AFib less reliant on oral anticoagulation, are now available on both sides of the Atlantic – as well as many other countries – after the Amulet’s United States market approval on Aug. 16, based largely on the Amulet IDE trial.

Rounding out the final Hot Line set is one of the latest efforts to show the efficacy and safety of a very short DAPT period after coronary stenting in patients with acute coronary syndromes, the STOPDAPT-2 ACS trial.

The study assigned 3,008 patients in Japan to receive aspirin and clopidogrel for either 1 month or 1 year after implantation with an everolimus-eluting cobalt-chromium stent and followed them for up to 5 years for a composite of MI, CV death, stent thrombosis, stroke, and bleeding.

The trial follows the published STOPDAPT-2 trial that showed superiority for the 1-month DAPT regimen in a predominantly stable-CAD population treated with the same kind of stent.
 

Program structure and format

A total of 15 online channels are to be available in the morning, European time, their schedules running in parallel. Presentations often are prerecorded, but also include live sessions at 8:00 a.m. Central time and 12 p.m. CET (2:00 a.m. and 6:00 a.m. Eastern time) to liven up the channel offerings, Dr. Windecker observed, and to make them more immediate and potentially interactive.

Many of the parallel channels are devoted throughout the Congress to particular silos of cardiology; for example, arrhythmias and device therapy is on channel 3; CAD and acute care is on 5; HF is on 6; and preventive cardiology is on 9.

Other channels swing across different topics from day to day, such as channel 1, which covers COVID-19 topics on the first and third day of the meeting, “advances in science” on day 2, and “digital health, public health, health economics” on day 4.

The focus each day, starting at 2:00 p.m. CET (8:00 a.m. ET) and continuing into the evening in Europe, shifts over to the Prime Time live program, which features the Hot Line and guideline presentations and many of the live abstract presentations.

Dr. Kosiborod, not a researcher with the EMPEROR trials, is chair of the Dapagliflozin in Preserved Ejection Fraction Heart Failure ( PRESERVED-HF ) trial, which is scheduled for presentation at the September 2021 Heart Failure Society of American meeting.

A version of this article first appeared on Medscape.com.

There will be so much more to the annual congress of the European Society of Cardiology, which begins Aug. 27 with an all-virtual format, than detailed primary results of EMPEROR-Preserved, a trial that could mark a turning point for heart failure (HF) medical therapy.

Also among the featured Hot Line and Late-Breaking Science sessions are – along with many other studies – explorations of arrhythmia management (ablation or guided by loop recorder); secondary prevention, including by vaccination; oral anticoagulation, notably after transcatheter valve procedures; and colchicine or thrombosis prophylaxis in hospitalized patients with COVID-19.

There will even be a head-to-head comparison of two long-familiar left atrial appendage (LAA) occluders, and a population-based, randomized trial of sodium restriction through wide-scale use of a potassium-based salt substitute.

The congress will also introduce four guideline documents at sessions throughout the Congress, one on each day. They cover new and modified recommendations for heart failure; pacing, including cardiac resynchronization therapy (CRT); cardiovascular (CV) disease prevention; and, with cosponsorship from the European Association for Cardio-Thoracic Surgery, valvular heart disease.
 

The virtues of virtual

That next year’s Congress is slated for Aug. 27-30 in Barcelona should be welcome news for anyone whose “what if” curiosity about all-virtual conferences has already been satisfied. But with experience comes wisdom, as the medical societies have learned that online scientific meetings have some winning qualities that may be worth keeping, as least for a while.

“I think there is no doubt that the digital format will continue, for several reasons. One is that this pandemic is not over,” ESC Congress program committee chair Stephan Windecker, MD, Bern (Switzerland) University Hospital, , told this news organization. “As long as it is not over, the digital format is here to stay.”

But it also appears that people who haven’t been able to attend the congress in person are keen to log in and engage online, Dr. Windecker said. The 2020 all-virtual conference drew a much younger pool of registrants, on average, than did the live conferences before the pandemic.

“I think that’s an indication of people that may be in training, in early stages of their career, or they don’t have the support from departments or from their practice, or other financial means.” But they are able to participate via computer, tablet, or smartphone, he said.

“Another advantage is that the recorded content can be replayed at the convenience of whoever wants to consume it at a later point in time,” he added. “Those are just some examples why the digital format is likely to stay,” on its own or in a new age of hybrid meetings.  
 

New and updated guidelines

Leading off the guideline series is the document on diagnosis and treatment of acute and chronic HF, which leveraged the past few busy years of HF clinical trials to arrive at a number of new recommendations and strengthened level-of-evidence ratings. It covers both drug and device therapy of HF with reduced ejection fraction (HFrEF) and acute decompensated HF, and tweaks and further enshrines the concept of HF with mildly reduced ejection fraction (HFmrEF).

Several updated recommendations for both long-used and novel medications, notably the sodium-glucose cotransporter 2 inhibitors, will be included because of the recently appreciated evidence-based impact in HFrEF, Dr. Windecker noted.

“I think it will be particularly interesting to look for the SGLT2 inhibitors as not a completely new class of drugs, but certainly one where there has been a lot of new evidence, to look at how those drugs will be integrated in the overall care pathway.”

A top-line preview of the new HF guideline limited to drug therapy, presented at July’s Heart Failure Association of the European Society of Cardiology (ESC-HFA), provided a simple answer to a common question in the new, bountiful age of HFrEF medications: Which meds, initiated in what order?

As it happens, the new recommendation for first-line HFrEF drug therapy is not a silver bullet, but a shotgun – prompt initiation of at least four meds, one from each of four drug classes: renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRA), and SGLT2 inhibitors. Each class, as described in the document, is to be started as soon as safely feasible, in a sequence deemed appropriate for each individual patient.
 

Spotlight on EMPEROR-Preserved

The world already knows that the trial, which tested the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) on top of standard therapy, “met” its primary endpoint in almost 6,000 patients with HF with preserved ejection fraction (HFpEF), who included some with HFmrEF by more contemporary definitions.

That means patients in EMPEROR-Preserved assigned to take empagliflozin showed significantly fewer events that made up the study’s primary endpoint, a composite of CV death or HF hospitalization. It appears to be the first clearly significant overall medical therapy benefit for a clinical primary endpoint in a major randomized HFpEF drug trial.

And that, pending fuller presentation of trial results at the Congress on Aug. 27, could be a huge deal for the half of HF patients with left ventricular ejection fractions (LVEF) higher than the HFrEF range.

Those early top-line results weren’t a decisive bombshell for a field now filled with hope for a practice-changing empagliflozin outcome in EMPEROR-Preserved, which isn’t a certainty. They were more like the “boom” of a mortar launching a rocket of fireworks that may explode into a chrysanthemum or green comet or, sometimes, turn out to be no more than a dud. The promise of the early cursory results critically depends on further details.

The trial has two groups: A prevention group of adults living and circulating in the community; and a treatment group of patients aged at least 40 years with confirmed symptomatic SARS-CoV-2 infection for whom the need for hospitalization isn’t clear.
 

Monday, Aug. 30

The final day of the Congress features a trial called Influenza Vaccination after Myocardial Infarction (IAMI), which has tested the secondary preventive effect of influenza vaccination by randomly assigning 2,571 patients to receive a standard vaccine or a saline placebo injection on one occasion.

Entry to the international trial called for a diagnosis of MI with or without ST-segment elevation, or stable CAD and age at least 75 years with other risk factors. The patients were followed for death, MI, stent thrombosis, and a slew of secondary endpoints over 12 months.

Monday offerings continue later in a time block leading off with the STEP trial, which has randomly assigned an estimated 8,000 patients at 40 centers in China who are 60 to 80 years of age with a systolic blood pressure of 140 to <190 mm Hg to be on standard guideline-based therapy or an intensive drug-management strategy.

The systolic BP goals are 130 to <150 mm Hg for standard care and 110 to <130 mm Hg for the intensive regimen. The composite primary endpoint includes death and clinical events related to acute coronary syndromes, HF, revascularization, and stroke.

Following on heels of STEP, the Amulet IDE trial – the first major randomized comparison of two transcatheter LAA closure devices – entered 1,878 patients with nonvalvular AFib who were considered high-risk for bleeding and stroke or systemic embolism.

They were randomly assigned in the noninferiority trial to receive either the AMPLATZER Amulet (Abbott Medical Devices) or the WATCHMAN (Boston Scientific) closure devices and were followed for safety and efficacy for up to 5 years.

Both LAA closure devices, intended to make patients with AFib less reliant on oral anticoagulation, are now available on both sides of the Atlantic – as well as many other countries – after the Amulet’s United States market approval on Aug. 16, based largely on the Amulet IDE trial.

Rounding out the final Hot Line set is one of the latest efforts to show the efficacy and safety of a very short DAPT period after coronary stenting in patients with acute coronary syndromes, the STOPDAPT-2 ACS trial.

The study assigned 3,008 patients in Japan to receive aspirin and clopidogrel for either 1 month or 1 year after implantation with an everolimus-eluting cobalt-chromium stent and followed them for up to 5 years for a composite of MI, CV death, stent thrombosis, stroke, and bleeding.

The trial follows the published STOPDAPT-2 trial that showed superiority for the 1-month DAPT regimen in a predominantly stable-CAD population treated with the same kind of stent.
 

Program structure and format

A total of 15 online channels are to be available in the morning, European time, their schedules running in parallel. Presentations often are prerecorded, but also include live sessions at 8:00 a.m. Central time and 12 p.m. CET (2:00 a.m. and 6:00 a.m. Eastern time) to liven up the channel offerings, Dr. Windecker observed, and to make them more immediate and potentially interactive.

Many of the parallel channels are devoted throughout the Congress to particular silos of cardiology; for example, arrhythmias and device therapy is on channel 3; CAD and acute care is on 5; HF is on 6; and preventive cardiology is on 9.

Other channels swing across different topics from day to day, such as channel 1, which covers COVID-19 topics on the first and third day of the meeting, “advances in science” on day 2, and “digital health, public health, health economics” on day 4.

The focus each day, starting at 2:00 p.m. CET (8:00 a.m. ET) and continuing into the evening in Europe, shifts over to the Prime Time live program, which features the Hot Line and guideline presentations and many of the live abstract presentations.

Dr. Kosiborod, not a researcher with the EMPEROR trials, is chair of the Dapagliflozin in Preserved Ejection Fraction Heart Failure ( PRESERVED-HF ) trial, which is scheduled for presentation at the September 2021 Heart Failure Society of American meeting.

There will be so much more to the annual congress of the European Society of Cardiology, which begins Aug. 27 with an all-virtual format, than detailed primary results of EMPEROR-Preserved, a trial that could mark a turning point for heart failure (HF) medical therapy.

Also among the featured Hot Line and Late-Breaking Science sessions are – along with many other studies – explorations of arrhythmia management (ablation or guided by loop recorder); secondary prevention, including by vaccination; oral anticoagulation, notably after transcatheter valve procedures; and colchicine or thrombosis prophylaxis in hospitalized patients with COVID-19.

There will even be a head-to-head comparison of two long-familiar left atrial appendage (LAA) occluders, and a population-based, randomized trial of sodium restriction through wide-scale use of a potassium-based salt substitute.

The congress will also introduce four guideline documents at sessions throughout the Congress, one on each day. They cover new and modified recommendations for heart failure; pacing, including cardiac resynchronization therapy (CRT); cardiovascular (CV) disease prevention; and, with cosponsorship from the European Association for Cardio-Thoracic Surgery, valvular heart disease.
 

The virtues of virtual

That next year’s Congress is slated for Aug. 27-30 in Barcelona should be welcome news for anyone whose “what if” curiosity about all-virtual conferences has already been satisfied. But with experience comes wisdom, as the medical societies have learned that online scientific meetings have some winning qualities that may be worth keeping, as least for a while.

“I think there is no doubt that the digital format will continue, for several reasons. One is that this pandemic is not over,” ESC Congress program committee chair Stephan Windecker, MD, Bern (Switzerland) University Hospital, , told this news organization. “As long as it is not over, the digital format is here to stay.”

But it also appears that people who haven’t been able to attend the congress in person are keen to log in and engage online, Dr. Windecker said. The 2020 all-virtual conference drew a much younger pool of registrants, on average, than did the live conferences before the pandemic.

“I think that’s an indication of people that may be in training, in early stages of their career, or they don’t have the support from departments or from their practice, or other financial means.” But they are able to participate via computer, tablet, or smartphone, he said.

“Another advantage is that the recorded content can be replayed at the convenience of whoever wants to consume it at a later point in time,” he added. “Those are just some examples why the digital format is likely to stay,” on its own or in a new age of hybrid meetings.  
 

New and updated guidelines

Leading off the guideline series is the document on diagnosis and treatment of acute and chronic HF, which leveraged the past few busy years of HF clinical trials to arrive at a number of new recommendations and strengthened level-of-evidence ratings. It covers both drug and device therapy of HF with reduced ejection fraction (HFrEF) and acute decompensated HF, and tweaks and further enshrines the concept of HF with mildly reduced ejection fraction (HFmrEF).

Several updated recommendations for both long-used and novel medications, notably the sodium-glucose cotransporter 2 inhibitors, will be included because of the recently appreciated evidence-based impact in HFrEF, Dr. Windecker noted.

“I think it will be particularly interesting to look for the SGLT2 inhibitors as not a completely new class of drugs, but certainly one where there has been a lot of new evidence, to look at how those drugs will be integrated in the overall care pathway.”

A top-line preview of the new HF guideline limited to drug therapy, presented at July’s Heart Failure Association of the European Society of Cardiology (ESC-HFA), provided a simple answer to a common question in the new, bountiful age of HFrEF medications: Which meds, initiated in what order?

As it happens, the new recommendation for first-line HFrEF drug therapy is not a silver bullet, but a shotgun – prompt initiation of at least four meds, one from each of four drug classes: renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists (MRA), and SGLT2 inhibitors. Each class, as described in the document, is to be started as soon as safely feasible, in a sequence deemed appropriate for each individual patient.
 

Spotlight on EMPEROR-Preserved

The world already knows that the trial, which tested the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) on top of standard therapy, “met” its primary endpoint in almost 6,000 patients with HF with preserved ejection fraction (HFpEF), who included some with HFmrEF by more contemporary definitions.

That means patients in EMPEROR-Preserved assigned to take empagliflozin showed significantly fewer events that made up the study’s primary endpoint, a composite of CV death or HF hospitalization. It appears to be the first clearly significant overall medical therapy benefit for a clinical primary endpoint in a major randomized HFpEF drug trial.

And that, pending fuller presentation of trial results at the Congress on Aug. 27, could be a huge deal for the half of HF patients with left ventricular ejection fractions (LVEF) higher than the HFrEF range.

Those early top-line results weren’t a decisive bombshell for a field now filled with hope for a practice-changing empagliflozin outcome in EMPEROR-Preserved, which isn’t a certainty. They were more like the “boom” of a mortar launching a rocket of fireworks that may explode into a chrysanthemum or green comet or, sometimes, turn out to be no more than a dud. The promise of the early cursory results critically depends on further details.

“Provided there is a compelling benefit, this is what everyone has been waiting for in this condition for decades,” Mikhail N. Kosiborod, MD, director of cardiometabolic research at Saint Luke’s Mid-America Heart Institute, Kansas City, Mo., said.

“Already knowing that the trial met the primary endpoint is obviously very intriguing and encouraging,” he added. “But there are things we don’t know, such as: What is the magnitude of benefit? And whether that benefit, whatever the magnitude, is driven by reductions in both heart failure hospitalizations and cardiovascular death, or only one of the two.”

For example: “If we see an impressive benefit for reduction of hospitalizations, but not a significant reduction in death, that would still be a huge advance. That’s because, to date, we don’t have any drug for HFpEF that has convincingly demonstrated a compelling reduction in heart failure hospitalization or improvement in symptoms, function, or quality of life,” observed Dr. Kosiborod, who wasn’t part of EMPEROR-Preserved.

There have been “suggestions” from HFrEF trials that empagliflozin and dapagliflozin (Farxiga, AstraZeneca) “have very comparable effects on at least the endpoint of cardiovascular death or hospitalization for heart failure,” he said. “So, my expectation would be that whatever is observed in EMPEROR-Preserved is likely a class effect, as well.”

Following EMPEROR-Preserved on the agenda is EMPEROR-Pooled, a patient-level combined analysis of the EMPEROR series of trials that spans the range of HF, regardless of ejection fraction or diabetes status, primarily exploring the effects of empagliflozin on renal function.
 

Other offerings, Friday, Aug. 27

Scheduled immediately after EMPEROR-Preserved is a presentation on the SMART-MI trial, which should clarify whether management guided by continuous ambulatory monitoring is effective in patients considered at especially high arrhythmic risk. Entry called for recent myocardial infarction and an LVEF of 36%-50% with evidence of cardiac autonomic dysfunction.

The trial randomly assigned 400 such patients to be or not be implanted with a Reveal LINQ (Medtronic) loop recorder and followed them for up to 18 months, primarily for detection of potentially serious arrhythmic events. Endpoints that involved mortality, hospitalization or other clinical events were secondary.

In a time slot preceding both SMART-MI and EMPEROR-Preserved, the GUIDE-HF trial is following a projected 3,600 patients with HF implanted with a CardioMEMS HF System (Abbott) pulmonary artery (PA) pressure sensor to explore the its value for guiding management.

The trial’s three cohorts, followed for at least 12 months, include randomized sensor-monitored and control groups of patients with New York Heart Association class 2-4 symptoms, as well as a third observational set of patients in NYHA class 3. That’s the indication for which the CardioMEMS monitor gained approval in the United States in 2014 based on the 2011 CHAMPION trial, and which fared just as well in the 2017 CHAMPION Post-Approval Study.

The Friday Hot Lines also include Dal-GenE, which has entered about 6,000 patients with recent MI to test the once-abandoned cholesterol ester transfer protein (CETP) inhibitor dalcetrapib (DalCor) for any secondary-prevention benefits when used selectively. The trial’s hook: All its patients are confirmed to have the AA genotype of the rs1967309 variant in the ADCY9 gene, which has been associated with a pronounced clinical response to CETP inhibition.

Saturday, Aug. 28

The direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists in patients with nonvalvular atrial fibrillation (AFib). But whether DOACs are similarly preferable in the growing world population of people who have undergone transcatheter aortic valve replacement (TAVR or TAVI), an issue explored with variable results in the ATLANTIS and GALILEO trials, is far from settled.

The ENVISAGE-TAVI AF trial explored the question for the factor X inhibitor edoxaban (Savaysa, Lixiana, Daiichi-Sankyo) in 1,400 patients with AFib and a transfemoral TAVR in the previous 5 days, who were randomly assigned to the DOAC or standard management along with discretionary antiplatelet therapy. They’ve been followed for up to 3 years for a composite endpoint of clinical events – including death, MI, and stroke – and for major bleeding.

The day will also feature MASTER DAPT, a comparison of two dual-antiplatelet therapy (DAPT) regimens in an estimated 4,300 patients considered to be high-risk for bleeding who had received the sirolimus-eluting Ultimaster (Terumo) coronary stent, which has a bioresorbable polymer coating.

Investigators have randomly assigned patients to receive either very-short-duration DAPT, for about a month after stenting, followed by a P2Y12 inhibitor alone for up to a year after the procedure; or a more conventional regimen of a P2Y12 inhibitor for 6-12 months with aspirin maintained for a total of 12 months.

Later that day, investigators from the FIGARO-DKD trial will present their results based on 7,437 patients with type 2 diabetes and chronic kidney disease (CKD), a much fuller version than the top-line findings announced by sponsor Bayer 3 months ago.

Those top-line results suggested that patients assigned to receive the nonsteroidal nonselective mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) on top of standard care benefited with a drop in risk for the primary endpoint of CV death or nonfatal CV events.

Finerenone was recently approved in the United States for treating patients with both type 2 diabetes and CKD based on the published FIDELIO-DKD trial, which had seen less CKD progression and fewer CV events in such patients who took the novel MRA.

Although similar in design to FIGARO-DKD, FIDELIO-DKD had entered fewer patients with early-stage diabetic kidney disease (DKD). That led researchers to pool the two trials’ populations to create a cohort that spans the spectrum of DKD severity. An analysis of the pooled cohort, dubbed FIDELITY, is on the schedule after FIGARO-DKD.

After FIDELITY is the prospective APAF-CRT trial that is following a projected 1,830 patients with permanent, symptomatic AFib and a recent hospitalization for AFib or HF and who were not good candidates for standard ablation. They were assigned to receive either atrioventricular junctional ablation followed by CRT, with or without a defibrillation, on top of optimal meds – a so-called “ablate-and-pace” strategy – or an implantable cardioverter defibrillator with rate-control drug therapy.

The new analysis represents the trial’s second phase in which mortality was followed for 4 years as the primary endpoint, in contrast to the previously reported initial phase that followed the first 102 patients for 2 years for the composite primary endpoint of death, worsening HF, and HF hospitalization. The first phase had halted enrollment before reaching its planned target of 280 patients after an interim analysis showed a significant benefit for ablate and pace. 

Next up: DECAAF 2, a randomized assessment of whether catheter ablation for AFib guided by delayed gadolinium enhancement on MRI, a proxy for scar tissue, can be more effective than standard AFib ablation by pulmonary vein isolation alone. An estimated 900 patients with persistent AFib who had never before undergone ablation for the arrhythmia were randomly assigned to one strategy or the other and followed for AFib recurrence over 18 months.
 

Sunday, Aug. 29

The TOMAHAWK trial aimed to clarify the optimal timing of invasive coronary angiography for resuscitated patients with non–ST-segment elevation out-of-hospital cardiac arrest, a broad population in a setting for which there is little randomized-trial guidance. Investigators randomly assigned 558 such patients to undergo immediate invasive angiography or to direct intensive care unit admission for initial standard care with discretionary delayed angiography. Patients were followed for all-cause mortality, with other clinical events and neurologic outcomes as secondary endpoints.

Next on the schedule, the RIPCORD-2 trial randomly assigned 1,100 patients with stable known or suspected coronary artery disease (CAD) to undergo conventional angiography alone or with added direct pressure-wire measurement of fractional flow reserve to guide management decisions. Primary outcomes include health care costs and patient-reported quality of life at 1 year.

Slated for later that day, the Asymptomatic Carotid Surgery Trial-2 (ACST-2) has entered an estimated 3600 patients with a substantial carotid artery narrowing not associated with symptoms but for which either carotid endarterectomy (CEA) or carotid artery stenting (CAS) was considered anatomically feasible. There also must have been “substantial uncertainty” regarding the optimal procedure choice.

The trial, conducted in 40 countries primarily in Europe and North America and launched in 2008, randomly assigned the patients to undergo either CEA or CAS, in both cases with appropriate medical therapy, and followed them for periprocedural events and up to 10 years for strokes and stroke-related events.

The LOOP study, which is to directly follow ACST-2, has explored whether screening for AFib using the Medtronic Reveal LINQ monitor in older patients with non-AFib stroke risk factors – with oral anticoagulation prescribed for those who test positive – can lower their risk for stroke or systemic embolism. It randomly assigned 6,000 such patients to care guided by the loop recorder or to standard care.

On a somewhat larger scale, the Salt Substitute and Stroke Study (SSaSS) randomly assigned a total of 20,996 people in about 600 villages across northern China and Tibet to sodium-restriction intervention and control groups by village. All participants had a history of stroke or were aged at least 60 years with uncontrolled hypertension.

As described by the trial’s online portal, participants in villages assigned to the intervention group were given a supply of a low-sodium, potassium-supplementing salt substitute to replace their own salt supplies, along with education on the health benefits of sodium restriction. Participants in control villages continued their normal diets and, at the trial’s beginning, received “advice to reduce their salt intake.” All were required to own a telephone.

Clinical events, including strokes and hospitalizations throughout a 5-year follow-up, were tracked by phone calls made to all participants every 6 months and were documented at follow-up home visits.

Sunday is also to feature a Late-Breaking Trials session with a focus on COVID-19, which leads off with COLCOVID, a test of colchicine in patients hospitalized for suspected SARS-CoV-2 infection and in acute respiratory distress.

The 1,279 participants in Argentina were randomly assigned to receive or not receive the potent anti-inflammatory agent on top of antivirals and other standard management and followed for death or new need for mechanical ventilation. A successful outcome would contrast with the RECOVERY trial, which terminated a colchicine group of patients hospitalized with COVID-19 because of a lack of efficacy earlier this year.

COLCOVID is to be followed by the MICHELLE trial of rivaroxaban (Xarelto, Bayer/Janssen) prophylaxis, compared with no preventive oral anticoagulant, in 320 patients who, when hospitalized with COVID-19, had been on parenteral anticoagulants because of an elevated risk for venous thromboembolism. The trial, conducted in Brazil, called for postdischarge rivaroxaban at a once-daily dosage of 10 mg for about 1 month.

The session also includes a presentation called “Insights into the Effects of the COVID-19 Pandemic: Comprehensive Analysis from the GUIDE-HF Trial,” the primary outcomes of which will be reported on the first day of the Congress.

Following is a presentation on the PREPARE-IT study of icosapent ethyl (Vascepa, Amarin), given at high dosages intended to be anti-inflammatory, compared with placebo, in an estimated 4,000 adults. The trial has two groups: A prevention group of adults living and circulating in the community; and a treatment group of patients aged at least 40 years with confirmed symptomatic SARS-CoV-2 infection for whom the need for hospitalization isn’t clear.
