Triglyceride-lowering fails to show CV benefit in large fibrate trial
Twenty-five percent reduction has no effect
CHICAGO – Despite a 25% reduction in triglycerides (TGs) along with similar reductions in very-low-density lipoprotein (VLDL), and remnant cholesterol, a novel agent failed to provide any protection in a multinational trial against a composite endpoint of major adverse cardiovascular events (MACE) in patients with type 2 diabetes.
“Our data further highlight the complexity of lipid mediators of residual risk among patients with insulin resistance who are receiving statin therapy,” reported Aruna Das Pradhan, MD, of Harvard Medical School, Boston, and Queen Mary University, London.
It is the most recent in a series of trials that have failed to associate a meaningful reduction in TGs with protection from a composite MACE endpoint. This is a pattern that dates back 20 years, even though earlier trials did suggest that hypertriglyceridemia was a targetable risk factor.
No benefit from fibrates seen in statin era
“We have not seen a significant cardiovascular event reduction with a fibrate in the statin era,” according to Karol Watson, MD, PhD, director of the UCLA Women’s Cardiovascular Health Center, Los Angeles.
In the statin era, which began soon after the Helsinki Heart Study was published in 1987, Dr. Watson counted at least five studies with fibrates that had a null result.
In the setting of good control of LDL cholesterol, “fibrates have not been shown to further lower CV risk,” said Dr. Watson, who was invited by the AHA to discuss the PROMINENT trial.
In PROMINENT, 10,497 patients with type 2 diabetes were randomized to pemafibrate, a peroxisome proliferator-activated receptor a (PPAR-a) agonist, or placebo. Pemafibrate is not currently available in North America or Europe, but it is licensed in Japan for the treatment of hypertriglyceridemia.
The primary efficacy endpoint of the double-blind trial was a composite endpoint of nonfatal myocardial infarction, ischemic stroke, coronary revascularization, or death.
The patients were eligible if they had TG levels from 200 to 400 mg/dL and HDL cholesterol levels of 40 mg/dL or below. Pemafibrate in a dose of 0.2 mg or placebo were taken twice daily. About two-thirds had a prior history of coronary heart disease. The goal was primary prevention in the remainder.
After a median follow-up of 3.4 years when the study was stopped for futility, the proportion of patients reaching a primary endpoint was slightly greater in the experimental arm (3.60 vs. 3.51 events per 100 patient-years). The hazard ratio, although not significant, was nominally in favor of placebo (hazard ratio, 1.03; P = .67).
When events within the composite endpoint were assessed individually, there was no signal of benefit for any outcome. The rates of death from any cause, although numerically higher in the pemafibrate group (2.44 vs. 2.34 per 100 patient years), were also comparable.
Lipid profile improved as predicted
Yet, in regard to an improvement in the lipid profile, pemafibrate performed as predicted. When compared to placebo 4 months into the trial, pemafibrate was associated with median reductions of 26.2% in TGs, 25.8% in VLDL, and 25.6% in remnant cholesterol, which is cholesterol transported in TG-rich lipoproteins after lipolysis and lipoprotein remodeling.
Furthermore, pemafibrate was associated with a median 27.6% reduction relative to placebo in apolipoprotein C-III and a median 4.8% reduction in apolipoprotein E, all of which would be expected to reduce CV risk.
The findings of PROMINENT were published online in the New England Journal of Medicine immediately after their presentation.
The findings of this study do not eliminate any hope for lowering residual CV risk with TG reductions, but they do suggest the relationship with other lipid subfractions is complex, according to Salim S. Virani, MD, PhD, a professor of cardiology at Baylor College of Medicine, Houston.
“I think that the lack of efficacy despite TG lowering may be largely due to a lack of an overall decrease in the apolipoprotein B level,” speculated Dr. Virani, who wrote an editorial that accompanied publication of the PROMINENT results.
He noted that pemafibrate is implicated in converting remnant cholesterol to LDL cholesterol, which might be one reason for a counterproductive effect on CV risk.
“In order for therapies that lower TG levels to be effective, they probably have to have mechanisms to increase clearance of TG-rich remnant lipoprotein cholesterol particles rather than just converting remnant lipoproteins to LDL,” Dr. Virani explained in an attempt to unravel the interplay of these variables.
Although this study enrolled patients “who would be predicted to have the most benefit from a TG-lowering strategy,” Dr. Watson agreed that these results do not necessarily extend to other means of lowering TG. However, it might draw into question the value of pemafibrate and perhaps other drugs in this class for treatment of hypertriglyceridemia. In addition to a lack of CV benefit, treatment was not without risks, including a higher rate of thromboembolism and adverse renal events.
Dr. Das Pradhan reported financial relationships with Denka, Medtelligence, Optum, Novo Nordisk, and Kowa, which provided funding for this trial. Dr. Watson reported financial relationships with Amarin, Amgen, Boehringer-Ingelheim, and Esperion.

Pulmonologist consult at COPD admission reduces risk of return
according to a retrospective cohort review presented at the annual meeting of the American College of Chest Physicians (CHEST).
“When stratified by severity of COPD at the time of admission, the difference in the readmission rate was even greater,” reported Nakisa Hekmat-Joo, MD, a third-year resident at Staten Island University Hospital, New York.
Just as protocols have been developed for prompt initiation of antibiotics in patients with septicemia or prompt revascularization in patients with ST-segment elevated myocardial infarction (STEMI), Dr. Hekmat-Joo said the data from this study warrant a larger trial to evaluate whether an AECOPD admission protocol is warranted to improve outcomes and lower costs.
In this study, all AECOPD admissions were included from a recent 2-year period at two Staten Island hospitals. Of these, 198 patients received a pulmonologist consult within 24 hours. The remaining 92 patients were not evaluated by pulmonologists but were admitted and then managed by residents, internists, or others.
The primary outcome was length of stay (LOS). Although the slightly lower LOS in pulmonologist-treated group did not approach significance (4.16 vs. 4.21 days; P = .88), the readmission rate at 90 days, which was a secondary outcome, was reduced by almost half (30.1% vs. 57.6%; P < .0001).
At admission, there was no significant difference between those receiving a pulmonologist consult and those who did not. The average O2 saturation was lower in the group seen by a pulmonologist (93% vs. 95.4%; P < .0001), but the most striking difference was the low relative readmission rate, which remained significant after controlling for severity and pulmonary function.
“When we stratified patients for baseline severity, the advantage of a pulmonologist consult was even greater for those with the most severe disease,” Dr. Hekmat-Joo said. Among those with the greatest severity, the 90-day readmission rate was nearly three times greater in the absence of a pulmonologist consult (72% vs. 28%).
Although the comparison of outcomes for those receiving a pulmonologist consult vs. those who did not was adjusted for COPD severity, the potential for pulmonologist consults to be ordered for those patients who looked the sickest would have likely worked against the study result.
“We speculate that pulmonologists were more likely than internists to treat beyond standard guidelines, particularly in the event of greater severity,” Dr. Hekmat-Joo explained. These steps might include earlier use of noninvasive positive pressure ventilation or earlier initiation of rehabilitation strategies.
There were several signals that a pulmonologist consult led to more rigorous care.
“The average time to follow-up after hospitalization was 23 days for the pulmonologist group and 66 days for the nonpulmonologist group,” said Dr. Hekmat-Joo, noting this difference was highly significant (P = .0052).
Based on these results, Dr. Hekmat-Joo and her co-investigators are now working on a protocol for COPD admissions that involves a pulmonologist consult within 24 hours of admission. She hopes to test this protocol in a prospective trial.
“COPD remains a major cause of death and consumes enormous health care resources. About 30% of the cost of COPD care is due to readmissions,” she said, noting that readmissions adversely impact quality of life.
Asked if there was sufficient staff at her institution to allow for a pulmonologist consult with every COPD admission, Dr. Hekmat-Joo acknowledged that this has to be demonstrated, but compelling evidence of a benefit might prompt a redistribution of resources.
“If we can show that readmissions are substantially reduced, adding staff to perform these consults would be a good investment,” said Dr. Hekmat-Joo, indicating that improved outcomes could also attract the attention of third-party payers and those tracking quality-of-care metrics.
There is a strong rationale for a randomized prospective trial to confirm the value of a pulmonologist consultation following admission for an acute exacerbation of COPD, according to Nicola A. Hanania, MD, director, Airways Clinical Research Center, Baylor College of Medicine, Houston.
The potential for benefit as seen in this retrospective study is a rational expectation and might be related to more appropriate therapy upon discharge as well as to earlier and more rigorous follow-up, according to Dr. Hanania. Although he cautioned that there is a meaningful risk of selection bias in a retrospective study, he thinks this study “is certainly probing an important issue.”
“Mortality from a hospitalized COPD exacerbation exceeds that of a myocardial infarction,” Dr. Hanania pointed out. Noting that all patients with an MI are evaluated by a cardiologist, he sees the logic of a pulmonologist consult – although he acknowledged that evidence is needed.
“I strongly believe that a prospective study is feasible and will answer the question in an unbiased manner if done properly,” he said in an interview. If a multicenter, well-controlled study was positive, it could change practice.
In the event of a study showing major clinical benefits, particularly a reduction in mortality, “I believe it is feasible to have a pulmonary consult to see every COPD exacerbation patient admitted to the hospital,” Dr. Hanania said.

Sexual activities in seniors: Experts advise on what to ask
Sexual activity in older adults is something of a taboo, rarely discussed and largely ignored by researchers.
But failing to address human sexuality in old age can lead doctors to ask seniors the wrong questions about sex – if they ask at all.
When researchers do look at the issue, they find surprises, as Janie Steckenrider, PhD, has learned. In a new study presented at the annual scientific meeting of the Gerontological Society of America, Dr. Steckenrider, a professor of political science at Loyola Marymount University, Los Angeles, found that previous attempts to qualify the sexual activities of seniors appear to be limited largely to partnered sex – despite the fact that many older people tend to practice “solo sex,” another term for masturbation.
“Maybe they don’t have a partner, or their partner has sexual dysfunction, or has died. There could be pain involved,” Dr. Steckenrider said. “In the hierarchy of sexual activity, penetrative sex is the cultural norm. As people get older, penetrative sex becomes less important. The hierarchy shifts to include more emotional intimacy like touching and fondling.”
Of the 17 survey questionnaires Dr. Steckenrider analyzed, 11 had questions that focused exclusively on sex with a partner. Nine defined sexual activity and just five included questions about masturbation.
Take, for example, a 2018 poll by researchers at the University of Michigan, Ann Arbor, who found that 40% of people ages 65-80 said they were sexually active. Meanwhile, nearly two thirds of older adults said they were interested in sex, and more than half said sex was important to their quality of life.
But Dr. Steckenrider said this poll, like others, left the term “sexually active” undefined – raising questions about the meaning of the findings.
Sheryl A. Kingsberg, PhD, chief of behavioral medicine in the department of obstetrics and gynecology at University Hospitals Cleveland Medical Center, said she was surprised so few of the studies analyzed by Dr. Steckenrider included masturbation in their definition of sex.
“Clinical trials of potential treatments for female sexual problems, like hypoactive sexual desire disorder or painful sex, include both definitions of sexual activity and questions about masturbation, she said. “Definitions also should not assume partnered sex is male or female,” she added.
Dr. Steckenrider and Dr. Kingsberg encouraged healthcare providers to address the sexual health of their patients by asking questions about their sexual health and concerns.
“Health care professionals cannot address sexual concerns if they don’t acknowledge their patients as sexual beings and inquire about sexual problems,” Dr. Kingsberg said.
The key, according to Dr. Steckenrider, is for clinicians to ask the right questions. But which ones?
Detail is crucial.
“I think that’s far better than asking whether they are sexually active, yes or no,” she said. “Ask: ‘How often have you engaged in these types of sexual activities?’ If you are looking for frequency, and be specific about the types of sex: kissing, fondling, or masturbation.”

In a new study presented at the annual scientific meeting of the Gerontological Society of America, Dr. Steckenrider, a professor of political science at Loyola Marymount University, Los Angeles, found that previous attempts to qualify the sexual activities of seniors appear to be limited largely to partnered sex – despite the fact that many older people tend to practice “solo sex,” another term for masturbation.
“Maybe they don’t have a partner, or their partner has sexual dysfunction, or has died. There could be pain involved,” Dr. Steckenrider said. “In the hierarchy of sexual activity, penetrative sex is the cultural norm. As people get older, penetrative sex becomes less important. The hierarchy shifts to include more emotional intimacy like touching and fondling.”
Of the 17 survey questionnaires Dr. Steckenrider analyzed, 11 had questions that focused exclusively on sex with a partner. Nine defined sexual activity and just five included questions about masturbation.
Take, for example, a 2018 poll by researchers at the University of Michigan, Ann Arbor, who found that 40% of people ages 65-80 said they were sexually active. Meanwhile, nearly two thirds of older adults said they were interested in sex, and more than half said sex was important to their quality of life.
But Dr. Steckenrider said this poll, like others, left the term “sexually active” undefined – raising questions about the meaning of the findings.
Sheryl A. Kingsberg, PhD, chief of behavioral medicine in the department of obstetrics and gynecology at University Hospitals Cleveland Medical Center, said she was surprised so few of the studies analyzed by Dr. Steckenrider included masturbation in their definition of sex.
“Clinical trials of potential treatments for female sexual problems, like hypoactive sexual desire disorder or painful sex, include both definitions of sexual activity and questions about masturbation, she said. “Definitions also should not assume partnered sex is male or female,” she added.
Dr. Steckenrider and Dr. Kingsberg encouraged healthcare providers to address the sexual health of their patients by asking questions about their sexual health and concerns.
“Health care professionals cannot address sexual concerns if they don’t acknowledge their patients as sexual beings and inquire about sexual problems,” Dr. Kingsberg said.
The key, according to Dr. Steckenrider, is for clinicians to ask the right questions. But which ones?
Detail is crucial.
“I think that’s far better than asking whether they are sexually active, yes or no,” she said. “Ask: ‘How often have you engaged in these types of sexual activities?’ If you are looking for frequency, and be specific about the types of sex: kissing, fondling, or masturbation.”

Sexual activity in older adults is something of a taboo, rarely discussed and largely ignored by researchers.

New research confirms recommendations on COVID-19 boosters in MS
, as currently recommended.
“We have shown that even MS patients whose B cells were depleted from circulation with ocrelizumab can mount immune responses to COVID-19 vaccines,” said lead study author Ilya Kister, MD, of NYU Langone’s Multiple Sclerosis Comprehensive Care Center in New York.
The findings were presented at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).
VIOLA study
The data stem from VIOLA, an ongoing prospective study of humoral and cellular immune responses to COVID-19 vaccines in 60 patients with MS receiving ocrelizumab at MS care centers at NYU Langone and the University of Colorado Denver.
The mean age of participants was 38 years, 73% were women, all had been taking ocrelizumab for a mean of 1.7 years, and 45% had had COVID-19 prior to vaccination.
The researchers examined antibody and cellular responses to the two-dose series of mRNA COVID-19 vaccine (80% received the Pfizer-BioNTech vaccine, 18% the Moderna vaccine, and 2% unknown) over 24 weeks. In addition, 57% of the participants received the third dose/booster.
Results showed that antibody and cellular responses to SARS-CoV-2 spike protein significantly increased after the two-dose mRNA COVID-19 vaccination, though antibody responses tended to peak between 4 and 12 weeks and declined thereafter. There was no significant decline in cellular responses at week 24.
“The third dose ‘booster’ again significantly increased antibody and cellular responses compared with the pre–third dose levels,” Dr. Kister said.
“Importantly, cellular responses remained elevated or even increased from 4 weeks to 12 weeks after third dose/booster. Overall, these data strongly support the need for a third dose in MS patients on ocrelizumab,” Dr. Kister added.
Participants with “hybrid immunity” (those who had been infected with SARS-CoV-2 and who had also been vaccinated for COVID) had markedly higher SARS-CoV-2–specific antibody and cellular responses than those of peers with vaccine-only immunity.
CDC recs
Looking ahead, Dr. Kister said the VIOLA investigators plan to present data on the durability of COVID-19 vaccines in ocrelizumab-treated patients up to 48 weeks after the third dose.
For immunocompromised patients, such as those taking ocrelizumab, the Centers for Disease Control and Prevention considers the third dose of mRNA vaccine not as a “booster” but as part of the regular vaccine series.
“In other words, all these patients should receive three doses as part of their ‘primary’ series,” Dr. Kister noted.
The CDC also recommends receiving the updated booster for COVID-19 that became available in September 2022 (the fourth dose of the vaccine).
“Our study did not evaluate the efficacy of this fourth dose; but based on our results, it is reasonable to suppose that the fourth dose would also lead to a further increase in immune defenses,” Dr. Kister said.
The VIOLA study is an investigator-initiated collaboration supported by F. Hoffmann-La Roche Ltd/Genentech Inc. Dr. Kister has reported no relevant financial relationships.

Thyroid nodule volume reduction correlates with energy in ablation
MONTREAL – In the treatment of thyroid nodules with radiofrequency ablation (RFA), the amount of energy delivered per unit volume of the nodule strongly correlates with the extent of nodule volume reduction after 6 and 12 months, suggesting an important indicator of treatment success.
The findings “provide an objective measure or goal energy input to achieve during the [RFA] procedure rather than relying only on the subjective judgment of sonographic changes, and in turn, produce more reliable outcomes for our patients,” first author Samantha A. Wolfe, MD, said in an interview.
Dr. Wolfe, of the department of otolaryngology – head and neck surgery at Johns Hopkins University, Baltimore, presented the findings at the American Thyroid Association annual meeting.
Commenting on the study, Insoo Suh, MD, an associate professor and associate vice chair of Surgical Innovation at New York University Langone Health, agreed that “an accounting of the total amount of energy delivered can be a useful additional data point for the operator when they are determining whether an ablation is successful.”
He noted, however, that the location of a nodule can be an important factor when deciding upon amounts of RF energy.
“Some target areas are too close for comfort to critical structures, such as the trachea or the recurrent laryngeal nerve, so sound judgment would dictate that the energy be dialed down in those areas, even if the price you pay is a slightly lower volume reduction,” he explained.
Analysis of patients given RFA at Johns Hopkins
RFA utilizes RF energy for the reduction of nodule compression and aesthetic symptoms, avoiding the need for thyroid hormone replacement or surgery.
And while decisions regarding RFA treatment location and duration are commonly guided by the operator’s judgment of sonographic changes, those assessments can potentially result in inconsistent outcomes.
In observing a relationship between higher amounts of RF energy and nodule volume reduction, Dr. Wolfe and associates conducted their prospective study of nodules treated by two experienced endocrine surgeons at Johns Hopkins between June 2019 and May 2022 at 6 and 12 months in relation to the amount of total energy delivered during the treatment.
The analysis included 101 nodules, which had a median initial volume of 12.9 mL.
After 6 months, the median volume reduction ratio was 60%, and at 12 months, the median reduction was 64%.
In terms of the goal of achieving 50% or more volume reduction at 6 months, the median energy delivered was significantly higher for nodules that did reach that goal compared with those that had a volume reduction of less than 50% (2,317 vs. 1,912 J/mL, respectively; P = .01).
The figures were similar at 12 months (2,031 vs. 1254 J/mL; P < .01).
In a logistic regression analysis, the amount of energy delivered strongly increased the odds of obtaining a volume reduction ratio of at least 50% (odds ratio, 2.58; P = .048).
“Every twofold increase in energy delivered increases the odds of achieving a 50% volume ratio reduction by 2.58 times,” Dr. Wolfe explained.
Likewise, the same twofold increase in energy delivered also increased the odds of achieving a greater than 80% volume ratio reduction by 2.55 times (OR, 2.55; P = .038), she added.
Information may help to decide who needs multiple ablations
Of note, the effect was stronger with smaller nodules. Those with an initial volume of less than 20 mL had a significantly greater volume ratio reduction than nodules that were 20 mL or larger (61% vs. 48%, respectively; P = .05).
The initial volume of nodules that did, and did not, achieve a 50% volume ratio reduction at 6 months were 10.9 mL versus 19.1 mL, and the initial volumes of those that did, and did not, have at least a 50% reduction at 12 months were 10.5 mL and 41.5 mL.
“At 6 and 12 months, the successfully treated nodules had a significantly smaller immediate initial volume than those that did not,” Dr. Wolfe said.
“This information may aid in identifying patients with large nodules that are less likely to achieve a greater than 50% volume reduction ratio and may require multiple treatments,” she added.
Other factors – including the probe tip size and total energy delivered – did not significantly correlate with volume ratio reduction at 6 or 12 months.
There was also no significant difference in terms of thyroid-stimulating hormone levels among nodules that achieved at least a 50% volume reduction and those that did not.
Nodules that did not have a satisfactory volume reduction at 12 months had a relatively large median total energy value delivered during ablation (103,463 J, compared with 25,969 J among those achieving more than 50% volume ratio reduction), which Dr. Wolfe said likely reflects that those nodules had a large initial volume.
“This speaks to the importance of describing the energy utilized per unit of nodule volume rather than just a gross measurement,” she said during her presentation.
Dr. Wolfe added that in terms of strategies for getting more energy into the nodule, a key approach is time.
“Sometimes you will see sonographic changes very quickly in the nodule, and it could be tempting to consider that area ablated and move on if you only rely on sonographic changes,” she said in an interview. “However, our research shows that, by spending more time, and thus inputting more energy into the nodule, we had better volume reduction.”
Dr. Wolfe and Dr. Suh reported no relevant financial relationships.

STEP TEENS: Semaglutide ‘gives hope’ to adolescents with obesity
Attendees at ObesityWeek® 2022 listened with much excitement to the results of the STEP TEENS phase 3 trial of once-weekly subcutaneous semaglutide 2.4 mg (Wegovy) in adolescents aged 12 up to 18 years old with obesity.
When a session panel member said that clinical trials of weight-loss medications for adolescents with obesity should henceforth stop using placebo controls – implying that comparison with the once-weekly injection semaglutide would be more informative – the audience applauded.
The results were also simultaneously published in the New England Journal of Medicine to coincide with the presentation.
The research “gives hope” to adolescents with obesity, their parents, and their doctors, the trial’s principal investigator, Daniel Weghuber, MD, said in an interview.
“Many of them have been struggling for such a long time – both the parents and the kids themselves,” said Dr. Weghuber, from the department of pediatrics, Paracelsus Medical University, Salzburg, Austria.
“It’s not an issue of lack of willpower,” he stressed. “That’s a major misunderstanding.”
“This drug [semaglutide] seems to enable people who are living with obesity to adhere to the recommendations that they may have been following for years and years but were [still] not able to achieve their goal,” he said. It “enables people to achieve their goals.”
Asked about any potential negative impact on normal growth, Dr. Weghuber pointed out that the average weight of study participants was 107 kg (236 lb). “I’m really not afraid of a 15-year-old with 107 kg losing 10%, 15%, 20%” of their weight, he said. There was no indication of a problem regarding normal growth or development in the study.
, he summarized.
Senior study author, Silva Arslanian, MD, who holds the Richard L. Day Endowed Chair in Pediatrics at the University of Pittsburgh, agreed. “The results are amazing,” said Dr. Arslanian in a press release issued by the University of Pittsburgh. “For a person who is 5 foot, 5 inches tall and weighs 240 pounds, the average reduction in BMI equates to shedding about 40 pounds.”
‘Mind-blowing, awesome’ results
The session at ObesityWeek® 2022, the annual meeting of the Obesity Society, was chaired by Aaron S. Kelly, PhD, professor of pediatrics and codirector of the center for pediatric obesity medicine at the University of Minnesota, Minneapolis.
Dr. Kelly led the SCALE TEENS clinical trial of liraglutide (Saxenda), also a glucagon-like peptide (GLP-1) agonist like semaglutide, for adolescents aged 12 up to 18 years with obesity, which assigned 125 participants to the daily injectable liraglutide group and 126 to the placebo group. SCALE TEENS was presented and published in May 2020, leading to the approval of liraglutide for obesity in this age group, in December 2020.
Dr. Kelly called on two experts who were not involved in the research to offer their comments, starting with Claudia K. Fox, MD, MPH.
“These results are mind-blowing,” said Dr. Fox, who is associate professor of pediatrics and codirector of the center for pediatric obesity medicine at the University of Minnesota.
“We are getting close to bariatric surgery results” in these adolescent patients with obesity, added Dr. Fox, who is an American Board of Obesity Medicine diplomate. To have 40% of patients attain normal weight, “that’s massive” and “life-changing,” she said. And improvement in quality of life is what families care most about. “I am super excited,” she commented.
Next, Dr. Kelly called on Sarah C. Armstrong, MD, director of the Duke Children’s Healthy Lifestyles Program, Duke University, Durham, N.C.
Dr. Armstrong is a member of the executive committee for the American Academy of Pediatrics Section on Obesity and a coauthor of the upcoming clinical practice guidelines that are being published.
Looking at more than 16,000 abstracts at the meeting shows that “watchful waiting is not effective,” Dr. Armstrong said.
200 teens with obesity, only 1 with overweight
Obesity affects almost one in five children and adolescents worldwide. The chronic disease is linked with decreased life expectancy and higher risk of developing serious health problems such as type 2 diabetes, heart disease, nonalcoholic fatty liver disease, sleep apnea, and certain cancers. Teenagers with obesity are also more likely to have depression, anxiety, poor self-esteem, and other psychological issues.
STEP TEENS enrolled 201 adolescents aged 12 up to 18 years with obesity (body mass index [BMI] ≥ 95th percentile) or overweight (BMI ≥ 85th percentile) plus at least one weight-related comorbidity.
Only one recruited patient fit the latter category; the rest had obesity.
Most patients (62%) were female. They had a mean age of 15.4 years, a mean BMI of 37 kg/m2, and a mean waist circumference of 110 cm (43 inches).
Patients were randomized 2:1 to receive a once-weekly 2.4-mg subcutaneous injection of semaglutide or placebo for 68 weeks, plus lifestyle intervention.
Dr. Weghuber noted that 89.6% of patients in the semaglutide group completed treatment.
The primary endpoint, mean change in BMI from baseline to week 68, was −16.1% with semaglutide and +0.6% with placebo (estimated difference, −16.7 percentage points; P < .001).
A second confirmatory endpoint, at least 5% weight loss at week 68, was met by 73% of patients in the semaglutide group versus 18% of patients in the placebo group (P < .001).
Reductions in body weight and improvements in waist circumference, A1c, lipids (except HDL cholesterol), and the liver enzyme alanine aminotransferase were greater with semaglutide than placebo.
The Impact of Weight on Quality of Life – Kids (IWQOL-Kids) questionnaire total score as well as scores for body esteem, family relation, physical comfort, and social life were better in the semaglutide group.
However, the incidence of gastrointestinal adverse events was greater with semaglutide than placebo (62% versus 42%).
Five participants (4%) in the semaglutide group and none in the placebo group developed gallstones (cholelithiasis).
Serious adverse events were reported in 11% of patients in the semaglutide group and 9% of patients in the placebo group.
‘Big change’ coming in guidelines for obesity in teens
Commenting on the upcoming new recommendations for adolescents, Dr. Armstrong noted “there’s going to be a strong recommendation” for therapy in the new guidelines for pediatric obesity. “That’s a big change,” she said.
In the lively question-and-answer session that followed, a clinician wanted to know what explained the very high rate of study completion during the COVID-19 pandemic (when STEP TEENS was conducted). “What can we learn?” he asked.
“The bottom line is the relationship” and “close communication” between study investigators and patients, Dr. Weghuber replied.
“The fast track is likely to lead to approval in adolescents,” another member of the audience noted. He wanted to know if the company is planning a trial of semaglutide in younger children.
They are, Dr. Weghuber replied, and one with liraglutide is already underway.
The SCALE KIDS clinical trial of liraglutide is randomizing 78 participants aged 6 up to 12 years for 56 weeks of treatment and 26 weeks of follow-up, with an estimated primary completion date of July 7, 2023.
The last words went to Dr. Fox. The current results “are indeed very awesome,” she said, yet “thousands of providers are hesitant” to prescribe medications for adolescents with obesity.
The trial was funded by Novo Nordisk. Dr. Weghuber has reported being a consultant for Novo Nordisk and member of the Global Pediatric Obesity Expert Panel for the company. Disclosures for the other authors are listed with the article. Dr. Kelly has reported receiving donated drugs from AstraZeneca and travel support from Novo Nordisk and serving as an unpaid consultant for Novo Nordisk, Orexigen Therapeutics, VIVUS, and WW (formerly Weight Watchers).

Attendees at ObesityWeek® 2022 listened with much excitement to the results of the STEP TEENS phase 3 trial of once-weekly subcutaneous semaglutide 2.4 mg (Wegovy) in adolescents aged 12 up to 18 years old with obesity.
When a session panel member said that clinical trials of weight-loss medications for adolescents with obesity should henceforth stop using placebo controls – implying that comparison with the once-weekly injection semaglutide would be more informative – the audience applauded.
The results were also simultaneously published in the New England Journal of Medicine to coincide with the presentation.
The research “gives hope” to adolescents with obesity, their parents, and their doctors, the trial’s principal investigator, Daniel Weghuber, MD, said in an interview.
“Many of them have been struggling for such a long time – both the parents and the kids themselves,” said Dr. Weghuber, from the department of pediatrics, Paracelsus Medical University, Salzburg, Austria.
“It’s not an issue of lack of willpower,” he stressed. “That’s a major misunderstanding.”
“This drug [semaglutide] seems to enable people who are living with obesity to adhere to the recommendations that they may have been following for years and years but were [still] not able to achieve their goal,” he said. It “enables people to achieve their goals.”
Asked about any potential negative impact on normal growth, Dr. Weghuber pointed out that the average weight of study participants was 107 kg (236 lb). “I’m really not afraid of a 15-year-old with 107 kg losing 10%, 15%, 20%” of their weight, he said. There was no indication of a problem regarding normal growth or development in the study.
, he summarized.
Senior study author, Silva Arslanian, MD, who holds the Richard L. Day Endowed Chair in Pediatrics at the University of Pittsburgh, agreed. “The results are amazing,” said Dr. Arslanian in a press release issued by the University of Pittsburgh. “For a person who is 5 foot, 5 inches tall and weighs 240 pounds, the average reduction in BMI equates to shedding about 40 pounds.”

FROM OBESITYWEEK® 2022
Combo thrombolytic approach fails to reduce ICH in stroke
A study evaluating a new approach using a combination of two thrombolytics designed to reduce bleeding risk in patients with acute ischemic stroke has not shown any benefit on the primary outcome of all intracranial hemorrhage (ICH).
However, there were some encouraging findings including a trend towards a reduction in symptomatic ICH, researchers report, and the combination approach did not show any depletion of fibrinogen levels, which suggests a potential lower bleeding risk.
“Although the main results of this study are neutral, we are encouraged that the combination approach with a low dose of alteplase followed by the new mutant pro-urokinase product looked as effective as full-dose alteplase alone, and there were some promising signs signaling a potential lower bleeding risk,” senior investigator, Diederik Dippel, MD, Erasmus University Medical Center, Rotterdam, the Netherlands, told this news organization.
The DUMAS study (Dual Thrombolytic Therapy With Mutant Pro-Urokinase and Low Dose Alteplase for Ischemic Stroke) was presented at the World Stroke Congress in Singapore by study coauthor Nadinda van der Ende, MD, also from Erasmus University Medical Center.
She pointed out that thrombolysis with intravenous alteplase increases the likelihood of a good outcome in acute ischemic stroke but can cause symptomatic intracranial hemorrhage, which can be associated with death and major disability.
Mutant pro-urokinase is a new thrombolytic agent, in development by Thrombolytic Science, Cambridge, Mass., formed by changing one amino acid in pro-urokinase to make it more stable. It is more fibrin specific than alteplase and therefore believed to have a lower risk of intracranial hemorrhage.
Fibrin is formed as the last step in the clotting process, and the precursor of fibrin in the blood is fibrinogen, Dr. van der Ende noted. Alteplase depletes fibrinogen, contributing to its increased bleeding risk, but mutant pro-urokinase is not believed to affect fibrinogen.
“Mutant pro-urokinase does not bind to intact fibrin. It only binds to fibrin that has already been primed by alteplase,” she explained.
The hypothesis behind the current study is that giving a small dose of alteplase will break down fibrin in the clot enough to expose the binding sites for mutant pro-urokinase, which can then be given to continue to lyse the clot.
As alteplase has a short half-life, it disappears quickly, and new fibrin is not affected. As mutant pro-urokinase can only lyse fibrin that is primed with alteplase, new hemostatic clots should stay intact. Animal studies have shown less bleeding from distant sites with this approach, Dr. van der Ende said.
The primary analysis of the phase 2 DUMAS study included 238 patients with mild ischemic stroke (median National Institutes of Health Stroke Scale [NIHSS] score 3) who met the standard criteria for IV alteplase.
They were randomized to alteplase alone at the regular dose of 0.9 mg/kg (max 90 mg) with a 10% bolus and the remaining given over 60 minutes; or to a combination of a 5-mg bolus of IV alteplase followed by mutant pro-urokinase at a dose of 40 mg given over 60 minutes.
The primary outcome was the rate of all intracranial hemorrhage (symptomatic and asymptomatic) detected by neuroimaging.
This occurred in 14% of patients in the full-dose alteplase group vs. 13% of patients in the combined alteplase/mutant pro-urokinase group, a nonsignificant difference: adjusted odds ratio, 0.99 (95% confidence interval, 0.46-2.14).
Secondary outcomes showed no significant differences in NIHSS scores at 24 hours or 5-7 days; functional outcome as measured by a shift analysis of the Modified Rankin Scale (mRS); final infarct volume; or perfusion deficit.
However, blood fibrinogen levels were not depleted and significantly higher in the alteplase/mutant pro-urokinase group than in the full-dose alteplase alone group.
In terms of safety, symptomatic ICH occurred in three patients in the alteplase group (3%) and in none (0%) in the combined alteplase/mutant pro-urokinase group; death occurred in 4% vs. 2% patients respectively; and major extracranial hemorrhage occurred in 1% in both groups.
Dr. Van der Ende concluded that the study showed an overall low rate of ICH; a combination of alteplase and mutant pro-urokinase was not superior to alteplase alone in reducing ICH rates in this population of patients with minor stroke; and mutant pro-urokinase appeared to be safe and, unlike alteplase, did not show any reduction in fibrinogen levels.
“We think the lack of an effect on fibrinogen with this new combination of a small alteplase bolus followed by mutant pro-urokinase infusion is promising,” Dr. Dippel commented. “The fact that there was no symptomatic ICH with the combination treatment is also encouraging. Although the primary endpoint of this trial was neutral, we still believe this is a very interesting approach, with the potential for reduced bleeding, compared with alteplase alone, but we need larger numbers to see an effect on outcomes.”
Dr. Dippel also pointed out that the study included only patients with minor stroke who were not eligible for endovascular therapy, and these patients have a low risk of a poor outcome and a low bleeding risk.
They are hoping to do another study in patients with more severe stroke, who have a higher bleeding risk and would have more to gain from this combination approach.
Because many patients with severe stroke now have immediate thrombectomy if they present to a comprehensive stroke center, a trial in severe stroke patients would have to be done in primary stroke centers, so if the patents are referred to thrombectomy, the thrombolytic would have a chance to work, Dr. Dippel added.
Commenting on the study for this news organization, Stefan Kiechl, MD, Medical University of Innsbruck (Austria), who is cochair of the World Stroke Congress scientific committee, said, “Alteplase is not fibrin specific, and also causes a degeneration of fibrinogen, which results in ‘fibrinogen depletion coagulopathy.’ It is assumed that 20%-40% of intracerebral bleeding after thrombolysis with alteplase is caused by this problem. DUMAS tests the combination of a substantially reduced alteplase [5 mg] dose plus mutant pro-urokinase to avoid this problem.”
The new thrombolysis protocol, however, did not result in a lower bleeding risk, compared to the comparator alteplase,” he added. “The main limitation of this study is that mainly patients with minor strokes were included. Patients with moderate and severe strokes, who have a substantial risk of bleeding, were not adequately addressed.”
The DUMAS trial was funded by an unrestricted grant from Thrombolytic Science, paid to the institution. Dr. Van der Ende and Dr. Dippel report no relevant disclosures.

Commenting on the study for this news organization, Stefan Kiechl, MD, Medical University of Innsbruck (Austria), who is cochair of the World Stroke Congress scientific committee, said, “Alteplase is not fibrin specific, and also causes a degeneration of fibrinogen, which results in ‘fibrinogen depletion coagulopathy.’ It is assumed that 20%-40% of intracerebral bleeding after thrombolysis with alteplase is caused by this problem. DUMAS tests the combination of a substantially reduced alteplase [5 mg] dose plus mutant pro-urokinase to avoid this problem.”
The new thrombolysis protocol, however, did not result in a lower bleeding risk, compared to the comparator alteplase,” he added. “The main limitation of this study is that mainly patients with minor strokes were included. Patients with moderate and severe strokes, who have a substantial risk of bleeding, were not adequately addressed.”
The DUMAS trial was funded by an unrestricted grant from Thrombolytic Science, paid to the institution. Dr. Van der Ende and Dr. Dippel report no relevant disclosures.

A study evaluating a new approach using a combination of two thrombolytics designed to reduce bleeding risk in patients with acute ischemic stroke has not shown any benefit on the primary outcome of all intracranial hemorrhage (ICH).
However, there were some encouraging findings including a trend towards a reduction in symptomatic ICH, researchers report, and the combination approach did not show any depletion of fibrinogen levels, which suggests a potential lower bleeding risk.
“Although the main results of this study are neutral, we are encouraged that the combination approach with a low dose of alteplase followed by the new mutant pro-urokinase product looked as effective as full-dose alteplase alone, and there were some promising signs signaling a potential lower bleeding risk,” senior investigator, Diederik Dippel, MD, Erasmus University Medical Center, Rotterdam, the Netherlands, told this news organization.
The DUMAS study (Dual Thrombolytic Therapy With Mutant Pro-Urokinase and Low Dose Alteplase for Ischemic Stroke) was presented at the World Stroke Congress in Singapore by study coauthor Nadinda van der Ende, MD, also from Erasmus University Medical Center.
She pointed out that thrombolysis with intravenous alteplase increases the likelihood of a good outcome in acute ischemic stroke but can cause symptomatic intracranial hemorrhage, which can be associated with death and major disability.
Mutant pro-urokinase is a new thrombolytic agent, in development by Thrombolytic Science, Cambridge, Mass., formed by changing one amino acid in pro-urokinase to make it more stable. It is more fibrin specific than alteplase and therefore believed to have a lower risk of intracranial hemorrhage.
Fibrin is formed as the last step in the clotting process, and the precursor of fibrin in the blood is fibrinogen, Dr. van der Ende noted. Alteplase depletes fibrinogen, contributing to its increased bleeding risk, but mutant pro-urokinase is not believed to affect fibrinogen.
“Mutant pro-urokinase does not bind to intact fibrin. It only binds to fibrin that has already been primed by alteplase,” she explained.
The hypothesis behind the current study is that giving a small dose of alteplase will break down fibrin in the clot enough to expose the binding sites for mutant pro-urokinase, which can then be given to continue to lyse the clot.
As alteplase has a short half-life, it disappears quickly, and new fibrin is not affected. As mutant pro-urokinase can only lyse fibrin that is primed with alteplase, new hemostatic clots should stay intact. Animal studies have shown less bleeding from distant sites with this approach, Dr. van der Ende said.
The primary analysis of the phase 2 DUMAS study included 238 patients with mild ischemic stroke (median National Institutes of Health Stroke Scale [NIHSS] score 3) who met the standard criteria for IV alteplase.
They were randomized to alteplase alone at the regular dose of 0.9 mg/kg (max 90 mg) with a 10% bolus and the remaining given over 60 minutes; or to a combination of a 5-mg bolus of IV alteplase followed by mutant pro-urokinase at a dose of 40 mg given over 60 minutes.
The primary outcome was the rate of all intracranial hemorrhage (symptomatic and asymptomatic) detected by neuroimaging.
This occurred in 14% of patients in the full-dose alteplase group vs. 13% of patients in the combined alteplase/mutant pro-urokinase group, a nonsignificant difference: adjusted odds ratio, 0.99 (95% confidence interval, 0.46-2.14).
Secondary outcomes showed no significant differences in NIHSS scores at 24 hours or 5-7 days; functional outcome as measured by a shift analysis of the Modified Rankin Scale (mRS); final infarct volume; or perfusion deficit.
However, blood fibrinogen levels were not depleted and significantly higher in the alteplase/mutant pro-urokinase group than in the full-dose alteplase alone group.
In terms of safety, symptomatic ICH occurred in three patients in the alteplase group (3%) and in none (0%) in the combined alteplase/mutant pro-urokinase group; death occurred in 4% vs. 2% patients respectively; and major extracranial hemorrhage occurred in 1% in both groups.
Dr. Van der Ende concluded that the study showed an overall low rate of ICH; a combination of alteplase and mutant pro-urokinase was not superior to alteplase alone in reducing ICH rates in this population of patients with minor stroke; and mutant pro-urokinase appeared to be safe and, unlike alteplase, did not show any reduction in fibrinogen levels.
“We think the lack of an effect on fibrinogen with this new combination of a small alteplase bolus followed by mutant pro-urokinase infusion is promising,” Dr. Dippel commented. “The fact that there was no symptomatic ICH with the combination treatment is also encouraging. Although the primary endpoint of this trial was neutral, we still believe this is a very interesting approach, with the potential for reduced bleeding, compared with alteplase alone, but we need larger numbers to see an effect on outcomes.”
Dr. Dippel also pointed out that the study included only patients with minor stroke who were not eligible for endovascular therapy, and these patients have a low risk of a poor outcome and a low bleeding risk.
They are hoping to do another study in patients with more severe stroke, who have a higher bleeding risk and would have more to gain from this combination approach.
Because many patients with severe stroke now have immediate thrombectomy if they present to a comprehensive stroke center, a trial in severe stroke patients would have to be done in primary stroke centers, so if the patents are referred to thrombectomy, the thrombolytic would have a chance to work, Dr. Dippel added.

Uptake of high-sensitivity troponin assays lags in U.S. hospitals
Most hospitals in the United States have yet to transition from conventional to high-sensitivity cardiac troponin (hs-cTn) assays, despite their greater sensitivity for myocardial injury, a new National Cardiovascular Data Registry (NCDR) registry study indicates.
hs-cTn assays have been used in routine clinical practice in Europe, Canada, and Australia since 2010, but the first such assay did not gain approval in the United States until 2017. Although single-center studies have examined their efficacy and potential downstream consequences, few data exist on hs-cTn implementation nationally, explained study author Cian McCarthy, MB, BCh, BAO, Massachusetts General Hospital, Boston.
The results were published online in the Journal of the American College of Cardiology and will be presented Nov. 5 at the American Heart Association scientific sessions.
For the study, Dr. McCarthy and colleagues examined 550 hospitals participating in the NCDR Chest Pain-MI registry from January 2019 through September 2021.
Of the 251,000 patients included in the analysis (mean age, 64 years; 41.5% female), 155,049 had a non–ST-segment myocardial infarction (NSTEMI), 15,989 had unstable angina, and 79,962 had low-risk chest pain.
The hs-cTn assays included Roche Diagnostic’s Elecsys Gen5 STAT troponin T assay (23%); Abbott’s ARCHITECT STAT (17%); Beckman Coulter’s ACCESS (21%); and Siemens’ Atellica IM (18%), Dimension VISTA (14%), Dimension EXL (4%), and ADVIA Centaur (2%) troponin I assays.
During the study period, 11.5% of patients were evaluated with hs-cTn assays and the remainder were evaluated with conventional troponin assays. These patients were slightly older (65.0 vs. 64.0 years), more commonly White (83.1% vs. 79.9%), less likely to be of Hispanic or Latino ethnicity (8.9% vs. 10.0%), and less likely to be uninsured (6.8% vs. 8.3%; P for all < .001).
A slightly higher proportion of patients evaluated with hs-cTn assays were diagnosed with unstable angina (7.1% vs. 6.3%), a lower proportion with NSTEMI (61.1% vs. 61.9%), and a similar proportion with low-risk chest pain (31.8% vs. 31.9%) compared with those evaluated by conventional troponin assays.
Implementation, defined as at least 25% of patients evaluated by hs-cTn in each quarter, increased from 3.3% in the first quarter of 2019 to 32.6% in the third quarter of 2021 (P trend < .001).
Using higher implementation thresholds of at least 50% and 75% of patients evaluated by hs-cTn, the prevalence in 2021 was 28.9% and 24.7%, respectively.
“So still, the majority of the hospitals by the end of the third quarter 2021 were not using these assays,” Dr. McCarthy said.
Potential explanations for the slow uptake are that prospective comparative effectiveness trials of These assays have predominantly been in international populations and real-world data on U.S. implementation have been limited to integrated health networks at academic institutions.
Approval of several assays was also delayed and the study data cut off just before the October publication of the 2021 AHA/ACC Chest Pain guideline. “So, whether the chest pain guideline with the new class 1 recommendation for hs-cTn will lead to further uptake is something that will need to be looked at in the future,” he said.
Downstream testing
In adjusted analyses, hs-cTn use was associated with more echocardiography among patients with non-ST elevation–acute coronary syndrome (NSTE-ACS) (82.4% vs. 75.0%; odds ratio [OR], 1.43; 95% confidence interval [CI], 1.19-1.73), but not among those with low-risk chest pain (19.7% vs. 19.4%; OR, 0.93; 95% CI, 0.71-1.22) compared with conventional cTn assays.
Importantly, hs-cTn was not associated with a difference in stress testing or CT coronary angiography utilization.
Use of hs-cTn was associated with lower use of invasive coronary angiography among patients with low-risk chest pain (3.7% vs. 4.5%; OR, 0.73, 95% CI, 0.58-0.92) but similar use for NSTE-ACS (96.3% vs. 95.8%; OR, 0.99, 95% CI, 0.82-1.19).
Among patients with NSTE-ACS, there also was no difference in revascularization with percutaneous coronary intervention (PCI) (52.7% vs. 52.3%; OR, 0.99; 95% CI, 0.94-1.04) or coronary bypass graft surgery (9.4% vs. 9.1%; OR, 1.06; 95% CI, 0.94-1.18).
PCI (0.1% vs. 0.2%; P = .05) and bypass graft surgery (both 0.1%) were uncommon among patients with low-risk chest pain.
In-hospital mortality was similar among patients with low-risk chest pain evaluated using hs-cTn assays vs. conventional troponin assays (0% vs. 0.02%; P = .16) and among patients with NSTE-ACS (2.8% vs. 3.2%; OR, 0.98, 95% CI, 0.87-1.11).
Length of stay was slightly shorter with hs-cTn use for patients with low-risk chest pain (median, 5.8 vs. 6.2 hours; P < .001) and patients with NSTE-ACS (66.9 vs. 67.8 hours; P = .01).
“There was always a concern that maybe high-sensitivity cardiac troponin would dramatically increase testing and could even increase length of stay, but I think these data are reassuring, in that this study suggests high-sensitivity cardiac troponin is associated with a small reduction in length of stay and possibly more appropriate use of testing with echocardiography in STEMI and a reduction in invasive angiography in low-risk patients,” Dr. McCarthy said. “But the majority of hospitals haven’t implemented the assay.”
The authors pointed out that because registry entry of patients with low-risk chest pain and unstable angina is optional for participating sites, the percentage of patients with NSTEMI is higher than in typical chest pain analyses. This higher pretest probability for MI may thus affect post-test accuracy for a true positive result. “That stated, this is the exact scenario where higher sensitivity might be associated with favorable impact on utilization.”
Among other limitations: There was the potential for unmeasured confounders, the accuracy of diagnoses could not be confirmed, patients with type 2 MI were excluded from the registry, and post-discharge safety was not assessed.
“These data indicate further opportunities to more widely and effectively implement hs-cTn in the U.S. hospitals persist that could optimize care for patients with possible or definitive ACS,” Dr. McCarthy and colleagues concluded.
The study was funded by the American College of Cardiology’s National Cardiovascular Data Registry. Dr. McCarthy is supported by the National Heart, Lung, and Blood Institute and has received consulting income from Abbott Laboratories.

Marital stress tied to worse outcome in young MI patients
Severe marital stress was associated with worse recovery after myocardial infarction in a large U.S. cohort of married/partnered patients aged 55 years or younger.
Compared with patients who reported no or mild marital stress a month after their MI, patients who reported severe marital stress had worse physical and mental health, worse generic and cardiovascular quality of life, more frequent angina symptoms, and a greater likelihood of having a hospital readmission a year later.
These findings held true after adjusting for gender, age, race/ethnicity, and baseline health status (model 1) and after further adjusting for education and income levels and employment and insurance status (model 2).
A greater percentage of women than men reported having severe marital stress (39% vs. 30%; P = .001).
Cenjing Zhu, MPhil, a PhD candidate at Yale University, New Haven, Conn., and colleagues will present this study at the American Heart Association scientific sessions.
The results show that “both patients and care providers should be aware that stress experienced in one’s everyday life, such as marital stress, can affect AMI [acute MI] recovery,” Ms. Zhu said in an email.
Health care providers should consider incorporating screening for everyday stress during follow-up patient visits to better spot people at high risk of a poor recovery and further hospitalizations, she added. When possible, they could guide patients to resources to help them manage and reduce their stress levels.
According to Ms. Zhu, the findings suggest that “managing personal stress may be as important as managing other clinical risk factors during the recovery process.”
This study in younger patients with MI “shows that high levels of marital stress impair heart attack recovery, and women have greater impairment in their heart attack recovery compared to men,” AHA spokesperson Nieca Goldberg, MD, who was not involved with this research, told this news organization.
The study shows that “clinicians have to incorporate mental health as part of their assessment of all patients,” said Dr. Goldberg, a clinical associate professor of medicine at New York University and medical director of Atria New York City.
“Our mental health impacts our physical health,” she noted. “Questions about marital stress should be included as part of an overall assessment of mental health. This means assessing all patients for stress, anxiety, and depression.”
Patients who are experiencing marital stress should share the information with their doctor and discuss ways to be referred to therapists and cardiac rehabilitation providers, she said. “My final thought is, women have often been told that their cardiac symptoms are due to stress by doctors. Now we know stress impacts physical health and [is] no longer an excuse but a contributing factor to our physical health.”
Does marital stress affect young MI recovery?
Previous literature has linked psychological stress with worse cardiovascular outcomes, Ms. Zhu noted.
However, little is known about the prognostic impact of marital stress on 1-year health outcomes for younger people who survive an MI.
To investigate this, the researchers analyzed data from participants in the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study.
The current study comprised 1,593 adults, including 1,020 female participants (64%), who were treated for MI at 103 hospitals in 30 U.S. states.
VIRGO enrolled participants in a 2:1 female-to-male ratio so as to enrich the inclusion of women, Ms. Zhu explained.
In the study, “partnered” participants were individuals who self-reported as “living as married/living with a partner.” There were 126 such patients (8%) in the current study.
The mean age of the patients was 47, and about 90% were 40-55 years old. Three quarters were White, 13% were Black, and 7% were Hispanic.
Marital stress was assessed on the basis of patients’ replies to 17 questions in the Stockholm Marital Stress Scale regarding the quality of their emotional and sexual relationships with their spouses/partners.
The researchers divided patients into three groups on the basis of their marital stress: mild or absent (lowest quartile), moderate (second quartile), and severe (upper two quartiles).
At 1 year after their MI, patients replied to questionnaires that assessed their health, quality of life, and depressive and angina symptoms. Hospital readmissions were determined on the basis of self-reports and medical records.
Compared to participants who reported no or mild marital stress, those who reported severe mental stress had significantly worse scores for physical and mental health and generic and cardiovascular quality of life, after adjusting for baseline health and demographics. They had worse scores for mental health and quality of life, after further adjusting for socioeconomic status.
In the fully adjusted model, patients who reported severe marital stress were significantly more likely to report more frequent chest pain/angina (odds ratio, 1.49; 95% confidence interval, 1.06-2.10; P = .023) and to have been readmitted to hospital for any cause (OR, 1.45; 95% CI, 1.04-2.00; P = .006), compared with the patients who reported no or mild marital stress.
Study limitations include the fact that the findings are based on self-reported questionnaire replies; they may not be generalizable to patients in other countries; and they do not extend beyond a period of 1 year.
The researchers call for further research “to understand this complex relationship and potential causal pathway associated with these findings.”
“Additional stressors beyond marital stress, such as financial strain or work stress, may also play a role in young adults’ recovery, and the interaction between these factors require further research,” Ms. Zhu noted in a press release from the AHA.
The study was funded by Canadian Institutes of Health Research. The VIRGO study was funded by the National Heart, Lung, and Blood Institute. Ms. Zhu and Dr. Goldberg have disclosed no relevant financial relationships.

Severe marital stress was associated with worse recovery after myocardial infarction in a large U.S. cohort of married/partnered patients aged 55 years or younger.
Compared with patients who reported no or mild marital stress a month after their MI, patients who reported severe marital stress had worse physical and mental health, worse generic and cardiovascular quality of life, more frequent angina symptoms, and a greater likelihood of having a hospital readmission a year later.
These findings held true after adjusting for gender, age, race/ethnicity, and baseline health status (model 1) and after further adjusting for education and income levels and employment and insurance status (model 2).
A greater percentage of women than men reported having severe marital stress (39% vs. 30%; P = .001).
Cenjing Zhu, MPhil, a PhD candidate at Yale University, New Haven, Conn., and colleagues will present this study at the American Heart Association scientific sessions.
The results show that “both patients and care providers should be aware that stress experienced in one’s everyday life, such as marital stress, can affect AMI [acute MI] recovery,” Ms. Zhu said in an email.
Health care providers should consider incorporating screening for everyday stress during follow-up patient visits to better spot people at high risk of a poor recovery and further hospitalizations, she added. When possible, they could guide patients to resources to help them manage and reduce their stress levels.
According to Ms. Zhu, the findings suggest that “managing personal stress may be as important as managing other clinical risk factors during the recovery process.”
This study in younger patients with MI “shows that high levels of marital stress impair heart attack recovery, and women have greater impairment in their heart attack recovery compared to men,” AHA spokesperson Nieca Goldberg, MD, who was not involved with this research, told this news organization.
The study shows that “clinicians have to incorporate mental health as part of their assessment of all patients,” said Dr. Goldberg, a clinical associate professor of medicine at New York University and medical director of Atria New York City.
“Our mental health impacts our physical health,” she noted. “Questions about marital stress should be included as part of an overall assessment of mental health. This means assessing all patients for stress, anxiety, and depression.”
Patients who are experiencing marital stress should share the information with their doctor and discuss ways to be referred to therapists and cardiac rehabilitation providers, she said. “My final thought is, women have often been told that their cardiac symptoms are due to stress by doctors. Now we know stress impacts physical health and [is] no longer an excuse but a contributing factor to our physical health.”
Does marital stress affect young MI recovery?
Previous literature has linked psychological stress with worse cardiovascular outcomes, Ms. Zhu noted.
However, little is known about the prognostic impact of marital stress on 1-year health outcomes for younger people who survive an MI.
To investigate this, the researchers analyzed data from participants in the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study.
The current study comprised 1,593 adults, including 1,020 female participants (64%), who were treated for MI at 103 hospitals in 30 U.S. states.
VIRGO enrolled participants in a 2:1 female-to-male ratio so as to enrich the inclusion of women, Ms. Zhu explained.
In the study, “partnered” participants were individuals who self-reported as “living as married/living with a partner.” There were 126 such patients (8%) in the current study.
The mean age of the patients was 47, and about 90% were 40-55 years old. Three quarters were White, 13% were Black, and 7% were Hispanic.

Race and gender: Tailoring treatment for sleep disorders is preferred and better
While trials of various interventions for obstructive sleep apnea and insomnia were effective, there was a strong suggestion that tailoring them according to the race/gender of the target populations strengthens engagement and improvements, according to a presentation by Dayna A. Johnson, PhD, MPH, at the annual meeting of the American College of Chest Physicians (CHEST).
Dr. Johnson, assistant professor at Emory University in Atlanta, stated that determinants of sleep disparities are multifactorial across the lifespan, from in utero to aging, but it was also important to focus on social determinants of poor sleep.
The complexity of factors, she said, calls for multilevel interventions beyond screening and treatment. In addition, neighborhood factors including safety, noise and light pollution, ventilation, and thermal comfort come into play.
Dr. Johnson cited the example of parents who work multiple jobs to provide for their families: “Minimum wage is not a livable wage, and parents may not be available to ensure that children have consistent bedtimes.” Interventions, she added, may have to be at the neighborhood level, including placing sleep specialists in the local neighborhood “where the need is.” Cleaning up a neighborhood reduces crime and overall health, while light shielding in public housing can lower light pollution.
Observing that African Americans have higher rates of obstructive sleep apnea, Dr. Johnson and colleagues designed a screening tool specifically for African Americans with five prediction models with increasing levels of factor measurements (from 4 to 10). The prediction accuracy across the models ascended in lockstep with the number of measures from 74.0% to 76.1%, with the simplest model including only age, body mass index, male sex, and snoring. The latter model added witnessed apneas, high depressive symptoms, two measures of waist and neck size, and sleepiness. Dr. Johnson pointed out that accuracy for well-established predictive models is notably lower: STOP-Bang score ranges from 56% to 66%; NoSAS ranges from 58% to 66% and the HCHS prediction model accuracy is 70%. Dr. Johnson said that a Latino model they developed was more accurate than the traditional models, but not as accurate as their model for African Americans.
Turning to specific interventions, and underscoring higher levels of stress and anxiety among African American and Hispanic populations, Dr. Johnson cited MINDS (Mindfulness Intervention to Improve Sleep and Reduce Diabetes Risk Among a Diverse Sample in Atlanta), her study at Emory University of mindfulness meditation. Although prior studies have confirmed sleep benefits of mindfulness meditation, studies tailored for African American or Hispanic populations have been lacking.
The MINDS pilot study investigators enrolled 17 individuals (mostly women, with a mixture of racial and ethnic groups comprising Black, White, Asian and Hispanic patients) with poor sleep quality as measured by the Pittsburgh Sleep Quality Index (PSQI). Most patients, Dr. Johnson said, were overweight. Because of COVID restrictions on clinic visits, the diabetes portion of the study was dropped. All participants received at least 3 days of instruction on mindfulness meditation, on dealing with stress and anxiety, and on optimum sleep health practices. While PSQI scores higher than 5 are considered to indicate poor sleep quality, the mean PSQI score at study outset in MINDS was 9.2, she stated.
After 30 days of the intervention, stress (on a perceived stress scale) was improved, as were PSQI scores and actigraphy measures of sleep duration, efficiency and wakefulness after sleep onset, Dr. Johnson reported. “Participants found the mindfulness app to be acceptable and appropriate, and to reduce time to falling asleep,” Dr. Johnson said.
Qualitative data gathered post intervention from four focus groups (two to six participants in each; 1-1.5 hours in length), revealed general acceptability of the MINDS app. It showed also that among those with 50% or more adherence to the intervention, time to falling asleep was reduced, as were sleep awakenings at night. The most striking finding, Dr. Johnson said, was that individuals from among racial/ethnic minorities expressed appreciation of the diversity of the meditation instructors, and said that they preferred instruction from a person of their own race and sex. Findings would be even more striking with a larger sample size, Dr. Johnson speculated.
Citing TASHE (Tailored Approach to Sleep Health Education), a further observational study on obstructive sleep apnea knowledge conducted at New York University, Dr. Johnson addressed the fact that current messages are not tailored to race/ethnic minorities with low-to-moderate symptom knowledge. Also, a 3-arm randomized clinical trial of Internet-delivered treatment (Sleep Healthy or SHUTI) with a version revised for Black women (SHUTI-BWHS) showed findings similar to those of other studies cited and suggested: “Tailoring may be necessary to increase uptake and sustainability and to improve sleep among racial/ethnic minorities.”
Dr. Johnson noted, in closing, that Black/African American individuals have higher risk for obstructive sleep apnea than that of their White counterparts and lower rates of screening for treatment.
Dr. Johnson’s research was funded by the National Institutes of Health; National Heart, Lung, and Blood Institute; Woodruff Health Sciences Center; Synergy Award; Rollins School of Public Health Dean’s Pilot and Innovation Award; and Georgia Center for Diabetes Translation Research Pilot and Feasibility award program. She reported no relevant conflicts.
