Use of race-based diabetes screening thresholds could reduce the disparity that arises from current screening guidelines in the United States, new research suggests.

In August 2021, the U.S. Preventive Services Task Force (USPSTF) lowered the recommended age for type 2 diabetes screening from 40 to 35 years among people with a body mass index of 25 kg/m² or greater.

However, the diabetes rate among ethnic minorities aged 35-70 years in the United States is not just higher overall but, in certain populations, also occurs more frequently at a younger age and at lower BMIs, the new study indicates.

Among people with a BMI below 25 kg/m², the diabetes prevalence is two to four times higher among Asian, Black, and Hispanic Americans than among the U.S. White population.

And the authors of the new study, led by Rahul Aggarwal, MD, predict that if screening begins at age 35 years, the BMI cut-off equivalent to 25 kg/m² for White Americans would be 18.5 kg/m2 for Hispanic and Black Americans and 20 kg/m² for Asian Americans.

“While diabetes has often been thought of as a disease that primarily affects adults with overweight or [obesity], our findings suggest that normal-weight adults in minority groups have surprisingly high rates of diabetes,” Dr. Aggarwal, senior resident physician in internal medicine at Harvard Medical School, Boston, told this news organization.

“Assessing diabetes risks in certain racial/ethnic groups will be necessary, even if these adults do not have overweight or [obesity],” he added.

Not screening in this way “is a missed opportunity for early intervention,” he noted.  

And both the authors and an editorialist stress that the issue isn’t just theoretical.

“USPSTF recommendations influence what payers choose to cover, which in turn determines access to preventative services ... Addressing the staggering inequities in diabetes outcomes will require substantial investments in diabetes prevention and treatment, but making screening more equitable is a good place to start,” said senior author Dhruv S. Kazi, MD, of the Smith Center for Outcomes Research in Cardiology and director of the Cardiac Critical Care Unit at Beth Israel, Boston.
 

Screen minorities at a younger age if current BMI threshold kept

In their study, based on data from the National Health and Nutrition Examination Survey (NHANES) for 2011-2018, Dr. Aggarwal and colleagues also calculated that, if the BMI threshold is kept at 25 kg/m², then the equivalent age cut-offs for Asian, Black, and Hispanic Americans would be 23, 21, and 25 years, respectively, compared with 35 years for White Americans.

The findings were published online  in the Annals of Internal Medicine.

The prevalence of diabetes in those aged 35-70 years in the NHANES population was 17.3% for Asian Americans and 12.5% for those who were White (odds ratio, 1.51 vs. Whites). Among Black Americans and Mexican Americans, the prevalence was 20.7% and 20.6%, respectively, almost twice the prevalence in Whites (OR, 1.85 and 1.80). For other Hispanic Americans, the prevalence was 16.4% (OR, 1.37 vs. Whites). All of those differences were significant, compared with White Americans.

Undiagnosed diabetes was also significantly more common among minority populations, at 27.6%, 22.8%, 21.2%, and 23.5% for Asian, Black, Mexican, and other Hispanic Americans, respectively, versus 12.5% for White Americans.
 

‘The time has come for USPSTF to offer more concrete guidance’

“While there is more work to be done on carefully examining the long-term risk–benefit trade-off of various diabetes screening, I believe the time has come for USPSTF to offer more concrete guidance on the use of lower thresholds for screening higher-risk individuals,” Dr. Kazi told this news organization.

The author of an accompanying editorial agrees, noting that in a recent commentary the USPSTF, itself, “acknowledged the persistent inequalities across the screening-to-treatment continuum that result in racial/ethnic health disparities in the United States.”

And the USPSTF “emphasized the need to improve systems of care to ensure equitable and consistent delivery of high-quality preventive and treatment services, with special attention to racial/ethnic groups who may experience worse health outcomes,” continues Quyen Ngo-Metzger, MD, Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, California.

For other conditions, including cancer, cardiovascular disease, and infectious disease, the USPSTF already recommends risk-based preventive services.

“To address the current inequity in diabetes screening, the USPSTF should apply the same consideration to its diabetes screening recommendation,” she notes.
 

‘Implementation will require an eye for pragmatism’

Asked about how this recommendation might be carried out in the real world, Dr. Aggarwal said in an interview that, because all three minority groups with normal weight had similar diabetes risk profiles to White adults with overweight, “one way for clinicians to easily implement these findings is by screening all Asian, Black, and Hispanic adults ages 35-70 years with normal weight for diabetes, similarly to how all White adults ages 35-70 years with overweight are currently recommended for screening.”

Dr. Kazi said: “I believe that implementation will require an eye for pragmatism,” noting that another option would be to have screening algorithms embedded in the electronic health record to flag individuals who qualify.

In any case, “the simplicity of the current one-size-fits-all approach is alluring, but it is profoundly inequitable. The more I look at the empiric evidence on diabetes burden in our communities, the more the status quo becomes untenable.”

However, Dr. Kazi also noted, “the benefit of any screening program relates to what we do with the information. The key is to ensure that folks identified as having diabetes – or better still prediabetes – receive timely lifestyle and pharmacological interventions to avert its long-term complications.”

This study was supported by institutional funds from the Richard A. and Susan F. Smith Center for Outcomes Research in Cardiology. Dr. Aggarwal, Dr. Kazi, and Dr. Ngo-Metzger have reported no relevant relationships.

Signs of cardiometabolic damage in children who are overweight appear as early as 6-8 years of age, but were not evident in preschoolers, providing a window of opportunity for intervention, show the latest results from a long-running Danish study of childhood weight.

The proportion of children who were overweight (nearly 14% in 2015) was similar between the two groups – those of preschool age (2-5 years) and school age (6-8 years) – but only the latter showed significant signs of cardiometabolic abnormalities.

The results, published in Obesity Research & Clinical Practice, are the latest in a series of many findings from the HOLBAEK study (formerly known as The Danish Childhood Obesity Biobank) that have emerged since it began in 2007. They were presented, along with a meta-analysis of much of their work, at the European Congress on Obesity (ECO) 2022.

“When comparing children with and without overweight, there were only barely significant differences among the preschool children,” said investigator Christine Frithioff-Bøjsøe, MD, but in contrast, “the school children with overweight exhibited significantly higher systolic blood pressure, glucose, insulin, and higher HDL cholesterol,” among other markers, she noted.

“Detection needs to start as early as age 2-5 years because if you wait just a few years longer these children will show early signs of disease starting to take hold. This could provide a critical window to detect and manage overweight,” said Frithioff-Bøjsøe, PhD, of the Children’s Obesity Clinic, Copenhagen University, Hospital Holbaek, Denmark.

Asked to comment, Aaron S. Kelly, PhD, professor of pediatrics, codirector, University of Minnesota Center for Pediatric Obesity Medicine in Minneapolis, said: “Recent results from HOLBAEK highlight the critical importance of identifying obesity early in life, before its complications spring up.

“Ideally, we should be in the business of managing and reducing excess adiposity as soon as it surfaces with the goal of preventing the onset of cardiometabolic risk factors, not watchful waiting and hoping for the best.”
 

Routine dental visits checked overweight

In the newest study, the researchers trained dental assistants to measure weight and height and carried out body mass index assessments during routine appointments.

A total of 335 preschool and 657 school-age children were recruited for the study. Of these, 40% attended additional hospital-based examinations including blood pressure measurement and a blood sample. Children were reexamined approximately 1 year later.

Systolic blood pressure, for example, was significantly higher in 6- to 8-year-olds with overweight compared to those of normal weight (P = .001). There was no significant difference between systolic blood pressure of 2.5- to 5-year-olds without and with overweight.

Likewise, with insulin resistance, there was no significant difference between preschoolers with and without overweight. However, in schoolchildren, homoeostasis model of assessment–insulin resistance (HOMA-IR) was significantly higher in those with overweight, at 2.2, compared to those without, at 0.9 (P < .001).

Also, during follow-up (around a year later), the prevalence of overweight did not change in preschool children but increased from 13.7% to 17.0% in schoolchildren.

The researchers noted that, in Europe, it is the primary health care sector that has continuous contact with the pediatric population, with the potential for early evaluation of children at risk. Their decision to use dental health care assistants to assess weight in this particular study is novel, but feasible, they observed.
 

Danish model for treating overweight and obesity is ‘game-changing’

As part of the HOLBAEK initiative, clinical data and biological samples have been collected from children and adolescents receiving treatment at The Children’s Obesity Clinic, Holbaek Hospital, using a population-based cohort as a reference group. Data have been collected on about 8,000 children and adolescents so far.

Jens-Christian Holm, PhD, along with colleague and research assistant Maria Frauland, both from Copenhagen University, Hospital Holbaek, presented a review of the HOLBAEK studies (2007-2021) at ECO 2022. They said the results highlight the importance of taking an integrated approach to managing children and adolescents with obesity.

The review, which included 82 papers, found a wide variety of obesity-related complications already present at a young age in some of the cross-sectional studies, including dyslipidemia in 28% of children with obesity, hepatic steatosis in 31%, obstructive sleep apnea in 45%, and prehypertension or hypertension in 52%.

The family-based interventional weight management programs adopted by HOLBAEK showed a 75% reduction in the “degree of obesity,” which comprised a measure of dyslipidemia, hypertension, hepatic steatosis, sleep apnea, and parental obesity.

“The HOLBAEK method is a holistic approach where we integrate everything,” Dr. Holm told this news organization.

Ms. Frauland said: “The HOLBAEK study has provided important insights into childhood overweight. It has highlighted that obesity is a serious multisystem disease that can be managed and treated effectively, reducing the degree of overweight and improving overweight-related complications.”

Dr. Kelly, the U.S. pediatrician, applauded the HOLBAEK philosophy, which emphasizes that obesity is not the fault of the child or parent, but rather the manifestation of dysregulated energy metabolism. “The recognition that obesity is a biologically driven, chronic, refractory, and relapsing disease is interwoven into the approach, which shifts the responsibility to the care provider for ensuring positive outcomes of treatment.

“Highlighting this fact to the parents and child can be game-changing since it removes the blame and shame associated with obesity and unburdens the family by framing the problem in a different light,” Dr. Kelly stressed.

Dr. Frithioff-Bøjsøe has reported no relevant financial relationships. Dr. Holm has an obesity management company called Holm. Dr. Kelly serves as an unpaid consultant for Novo Nordisk, Vivus, Eli Lilly, and Boehringer Ingelheim and receives donated drug/placebo from Vivus for a clinical trial funded by the National Institutes of Health.

They said the results highlight the importance of taking an integrated approach to managing children and adolescents with obesity.

The review, which included 82 papers, found a wide variety of obesity-related complications already present at a young age in some of the cross-sectional studies, including dyslipidemia in 28% of children with obesity, hepatic steatosis in 31%, obstructive sleep apnea in 45%, and prehypertension or hypertension in 52%.

The family-based interventional weight management programs adopted by HOLBAEK showed a 75% reduction in the “degree of obesity,” which comprised a measure of dyslipidemia, hypertension, hepatic steatosis, sleep apnea, and parental obesity.

“The HOLBAEK method is a holistic approach where we integrate everything,” Dr. Holm told this news organization.

Ms. Frauland said: “The HOLBAEK study has provided important insights into childhood overweight. It has highlighted that obesity is a serious multisystem disease that can be managed and treated effectively, reducing the degree of overweight and improving overweight-related complications.”

Dr. Kelly, the U.S. pediatrician, applauded the HOLBAEK philosophy, which emphasizes that obesity is not the fault of the child or parent, but rather the manifestation of dysregulated energy metabolism. “The recognition that obesity is a biologically driven, chronic, refractory, and relapsing disease is interwoven into the approach, which shifts the responsibility to the care provider for ensuring positive outcomes of treatment.

“Highlighting this fact to the parents and child can be game-changing since it removes the blame and shame associated with obesity and unburdens the family by framing the problem in a different light,” Dr. Kelly stressed.

Dr. Frithioff-Bøjsøe has reported no relevant financial relationships. Dr. Holm has an obesity management company called Holm. Dr. Kelly serves as an unpaid consultant for Novo Nordisk, Vivus, Eli Lilly, and Boehringer Ingelheim and receives donated drug/placebo from Vivus for a clinical trial funded by the National Institutes of Health.

Counting calories, joining a gym, and taking part in exercise programs are popular methods used by people in the United Kingdom who want to shed some pounds, but they seem to be fairly ineffective strategies, according to an investigation.

A survey of adults with obesity from six countries in western Europe found that most who set out to reduce a meaningful amount of weight failed in their attempt.

The preliminary results, presented in two posters at the European Congress on Obesity, underlined the need for better support and solutions for weight management, the authors suggested.

Marc Evans, MB, BCh, a consultant physician in diabetes and endocrinology, from University Hospital, Cardiff, Wales, who led the analysis, said that, “while obesity’s impact on health is well known, our finding that a sizable proportion of adults with obesity appear at elevated risk of hospitalization or surgery due to multiple underlying illnesses, undoubtedly adds a sense of urgency to tackling Europe’s growing obesity epidemic.”

The study, which also involved analytics consultancy firm Lane Clark & Peacock, conducted a cross-sectional survey of 1,850 adults. Of those 500 were from the UK, and the remainder from France, Germany, Italy, Spain, and Sweden.

All participants had a body mass index of 30 kg/m², or higher. More specifically, 56.3%; were classified as obesity class I, 26.8% obesity class II, and 16.9% obesity class III.
 

Obesity-related conditions

In total, 25.7% of participants reported no obesity-related health conditions, 28.4% had one condition, 19.6% had two, and 26.3% had three or more. The most common comorbidities were hypertension, dyslipidemia, and type 2 diabetes.

Overall, 78.6% of respondents reported having tried to lose weight in the previous year. Asked in a questionnaire about how they had tried to achieve this, the responses indicated that the most common strategies were:

• Calorie-controlled/restricted diet (71.9%)
• Exercise program course (21.9%)
• Pharmaceutical treatment/medication (12.3%)
• Joined a gym (12%)
• Digital health app (9.7%)

Among other participants, 8.1% said they had used alternative treatments, 7.6% a weight loss service, and 2.1% cognitive-behavioral therapy.

Analysis of the survey results showed that 78% of the individuals who attempted to lose weight did not achieve a clinically meaningful loss of 5% or more of their body weight, while some actually weighed more afterward.

Exercise and restricted diet

Notably, while exercise and calorie-controlled or restricted diets were among the most popular weight-loss methods in U.K. participants, they were amongst the least successful strategies. For instance, while 26.5% of adults who controlled their diet said they had lost weight, 17.1% reported their weight had increased. For those who took part in an exercise program, 33.3% said they lost weight, but 15.5% said they gained weight.

Signing up for gym membership also scored poorly, with 27% shedding weight, compared with 32.4% who put weight on.

“Our survey results indicate that, while the majority of adults with obesity are actively trying to reduce their weight, using a variety of strategies, most are unsuccessful,” said Dr. Evans.

Further studies were needed to assess whether people who lose weight succeed in maintaining their weight loss, the authors said.

The conference posters have yet to be published in a journal but were peer reviewed by the ECO selection committee.

The studies were sponsored by Novo Nordisk, a researcher into and manufacturer of diabetes and obesity medications, and employer of several of the coauthors.

New research suggests physicians face a Herculean task to get Americans with atherosclerotic cardiovascular disease (ASCVD) to take high-intensity statins, despite multiple professional guidelines giving the therapy their highest level recommendation.

Results from more 600,000 commercially insured patients with established ASCVD showed:

• Only one in five patients (22.5%) were taking a high-intensity statin.
• 27.6% were taking a low- or moderate-intensity statin.
• One-half (49.9%) were not taking any statin.

“It’s embarrassing,” senior author Christopher B. Granger, MD, Duke Clinical Research Institute, Durham, N.C., told this news organization. “It should be embarrassing for anybody in health care that we do such a terrible job with something so simple and effective.”

The results were published in the Journal of the American College of Cardiology.

Statins have been shown to reduce the risk for ASCVD events by about 30%, with an added 15% reduction with a high-intensity formulation. The class I recommendation for high-intensity statin use in ASCVD patients younger than 75 years in the 2013 American College of Cardiology/American Heart Association cholesterol guidelines prompted a jump in prescriptions that plateaued by 2017.

A class II recommendation was added to the 2018 guideline update for high-intensity statins in adults older than 75 years with ASCVD. But underuse persists, despite falling prices with generic availability and initiatives to improve statin adoption, the authors noted.

“There are a lot of barriers for patients to statin use, including the misinformation on the Internet and elsewhere that statins have all kinds of side effects,” Dr. Granger said. “They have uncommon side effects, but when we look at it carefully, only about 10% of patients, even with statin intolerance, have true intolerance.”

Efforts are needed to better understand and address these barriers, particularly for younger and female patients, he noted.

In multivariate analyses, patients who were middle-aged (odds ratio, 2.66) or at least 75 years of age (OR, 2.09) were more than twice as likely as patients younger than 45 years to be on any statin.

Not surprisingly, women were 30% less likely than men to receive a statin (OR, 0.70), Dr. Granger said. A high Charlson comorbidity score (OR, 0.72) and peripheral artery disease (OR, 0.55) also reduced the odds of a statin prescription.

Among statin users, middle-aged (OR, 0.83) and older (OR, 0.44) patients were less likely to be on a high-intensity statin, as were women (OR, 0.68) and patients with peripheral artery disease (OR, 0.43).

Visiting a cardiologist in the previous 12 months, however, increased the odds a patient was on a high-intensity statin (OR, 1.21), as did the use of other LDL-cholesterol-lowering drugs (OR, 1.44).

“With no evidence of heterogeneity in efficacy by sex, ongoing work must not only address misperceptions and barriers to the prescription of high-intensity statins in women, but also further understand (and address) differences in tolerability, which may be related to sex-based variation in statin metabolism,” wrote the authors, led by Adam J. Nelson, MBBS, MBA, MPH, also from Duke.

The study involved 601,934 patients (mean age, 67.5 years) who had a diagnosis of ASCVD between Jan. 31, 2018, and an index date of Jan. 31, 2019, and were enrolled in the HealthCore Integrated Research Environment database.

Two-thirds (70.9%) of patients visited a cardiologist in the 12 months prior to the index date, and three-fourths (81.3%) visited a primary care provider.

Pharmacy claims for the 12 months after the index date showed 82.8% of high-intensity users at index achieved coverage for at least 75% of days. Those with the least adherence (< 50% of days covered) included younger patients, as well as those with chronic kidney disease or depression.

“We need implementation research. What are the tools and the methods that we can use to improve the proportion of patients who are having the life-saving benefits from statins?” Dr. Granger said.

He noted that the team has submitted a National Institutes of Health grant to try to use pharmacists, as a mechanism within the context of health systems and payer systems, to improve the appropriate use of statins in a randomized trial. “I think that’s a win.”

Salim S. Virani, MD, PhD, Baylor College of Medicine, and Michael DeBakey VA Medical Center, Houston, and colleagues point out in a related editorial that the rates of statin usage in the study are “considerably lower” than in other contemporary studies, where about 80% and 50% of ASCVD patients are receiving statins and high-intensity statins, respectively.

Possible explanations are the use of rule-out codes, a short medication fill window from the index date, or issues with medication capture, they said. “Nevertheless, the findings are largely consistent with other work highlighting low use of statin therapy.”

The editorialists said social media, statin-related adverse effects, and therapeutic inertia are key drivers of non–guideline-concordant statin use. Possible solutions include improving guideline dissemination, leveraging team-based care, using smart clinical decision-support tools at the point of care, and identifying trustworthy and easily understood sources of information for patients.

“We can only hope that the fate of statin therapy is not repeated with sodium-glucose cotranspoerter-2 inhibitors or glucagon-like peptide-1 receptor agonists in another 30 years, or worse yet, that continued gaps in statin therapy use in patients with ASCVD persist 30 years from now,” Dr. Virani and colleagues concluded.

A sliver of optimism?

A research letter by Colantonio et al. in the same issue of JACC points to some positive steps, at least among patients having a myocardial infarction (MI). It reported that the percentage of patients who received a high-intensity statin as their first statin prescription 30 days after MI jumped from 30.7% in the first quarter of 2011 to 78.6% in the fourth quarter of 2019.

Similar increases were reported by race/ethnicity, despite statin use previously shown to be lower among non-Hispanic Black patients with ASCVD. In each calendar year, however, high-intensity statin therapy was lower among patients older than 75 years and among women.

Dr. Granger disclosed ties with Boehringer Ingelheim, Bristol Myers Squibb, Janssen Pharmaceuticals, Pfizer, AKROS, Apple, AstraZeneca, Daiichi Sankyo, Food and Drug Administration, GlaxoSmithKline, Medtronic Foundation, Novartis Pharmaceuticals, AbbVie, Bayer, Boston Scientific, CeleCor Therapeutics, Correvio, Espero BioPharma, Medscape, Medtronic, Merck, National Institutes of Health, Novo Nordisk, Rhoshan Pharmaceuticals, and Roche Diagnostics. Dr. Virani disclosed ties with the Department of Veterans Affairs, the National Institutes of Health, the World Heart Federation, and the Jooma and Tahir Family, and the American College of Cardiology.

CHICAGO – Recent research has changed at least one physician’s understanding of obesity and boosted her hope for fighting it.

Caroline Apovian, MD, codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital, described some of the new insights about obesity she has gained during her talk at the annual meeting of the American College of Physicians.

“When I was a medical student a while back, I learned that fat tissue just sat there and stored fat,” she said. “Now we know it’s an endocrine organ.”

This tissue secretes hormones, such as leptin, and other factors that have an array of effects on the brain, pancreas, heart, liver, and muscles. Moreover, it has plasticity, with the ability to change, constantly adjusting our metabolism as nutrient supply and demand changes, she continued.

Obesity leads to a decline in this plasticity, leading to fibrosis and inflammation and other problems. These changes can further impair the function of adipose tissue, leading to metabolic disease. But the central role of adipose tissue, and its dynamic nature, presents an opportunity for treatment, Dr. Apovian said, during her talk.
 

Hints to why obesity has become more common

More than 42% of the U.S. population – “unbelievably,” Dr. Apovian said – is obese, meaning they have a BMI over 30, according to the Centers for Disease Control and Prevention. That’s up by about 25% since 1960, although calories eaten hasn’t increased, and physical activity has increased somewhat, she said.

The root cause is still a bit of a mystery, but according to “good hints and clues” from animal models that are starting to be translated to the study of human obesity, “it has to do with epigenetics and how our brains and our bodies are perceiving the environment,” she noted, during her presentation.

“Our genes haven’t changed. Our environment has changed,” she said.

The industrialization of the food supply, the use of pesticides and preservatives, the dawn of fast food have all combined, most likely, to do “a number on our bodies,” Dr. Apovian said.

But not all hope is lost thanks to new research, Dr. Apovian suggested.
 

New treatments show promise for helping patients’ obesity

New research that has increased Dr. Apovian’s understanding of the sophisticated role of adipose tissue may be helpful for treating patients with obesity, offering more targets for intervention, she told the audience.

Some treatment avenues already identified have started producing results, Dr. Apovian noted.

Gastric bypass surgery typically leads to a loss of 25% of body weight, but is often shunned by patients, she said. “With such a great surgical procedure, we still only do 256,000 procedures and we have millions of Americans with a BMI over 30.”

Weight control with obsessive dieting, meal-planning and calorie-counting, “can be done, but it’s really hard,” Dr. Apovian noted.

More appealing therapies targeting hormones and appetite suppression have produced impressive results. Recently approved semaglutide produced 14% weight loss, compared with about 2% for placebo, she said.

Results just released for tirzepatide, a dual agonist of gut hormones GLP-1 and GIP, show a 22% total weight loss, compared with about 2% for placebo, with about 56% of patients losing more than 20% of their body weight, Dr. Apovian said.

Referencing studies finding that several hormones are altered during weight loss, she predicted that targeting multiple hormones with drug treatment will also be necessary for best results.

But, she noted, “we’re treating obesity now with one- or two-drug combos.”
 

Medication costs are too high for many patients

Isis Smith, MD, an internist at University Medical Center in New Orleans, said in an interview that the cost of the most effective medications – which are not covered by Medicaid – means that many of her patients don’t have access to these treatments.

“We’re talking about $1,000 a month. And so there is no way they can afford [them]. I can prescribe phentermine [but] unless a patient has another indication, Medicaid will not pay for it,” she explained.

“I love hearing about all of the new developments. ... It’s interesting to hear, but we need to get insurance to pay so that I can actually prescribe,” Dr. Smith noted.

Dr. Apovian reports financial relationships with Xeno Biosciences, Cowen, Allergan, Novo Nordisk, Abbott Nutrition, and other companies.

Mild traumatic brain injury (TBI) is linked to a significantly increased risk for a host of subsequent cardiovascular, endocrine, neurologic, and psychiatric disorders, new research shows.

Incidence of hypertension, coronary heart disease, diabetes, stroke, depression, and dementia all began to increase soon after the brain injury and persisted over a decade in both mild and moderate to severe TBI.

Researchers found the multisystem comorbidities in all age groups, including in patients as young as 18. They also found that patients who developed multiple postinjury problems had higher mortality during the decade-long follow-up.

The findings suggest patients with TBI may require longer follow-up and proactive screening for multisystem disease, regardless of age or injury severity.

“The fact that both patients with mild and moderate to severe injuries both had long-term ongoing associations with comorbidities that continued over time and that they are cardiovascular, endocrine, neurologic, and behavioral health oriented was pretty striking,” study author Ross Zafonte, DO, PhD, president of Spaulding Rehab Hospital and professor and chair of physical medicine and rehab at Harvard Medical School, both in Boston, told this news organization.

The study was published online in JAMA Network Open.
 

Injury severity not a factor

An estimated 2.8 million individuals in the United States experience TBI every year. Worldwide, the figure may be as high as 74 million.

Studies have long suggested a link between brain injury and subsequent neurologic disorders, but research suggesting a possible link to cardiovascular and endocrine problems has recently gained attention.

Building on a 2021 study that showed increased incidence of cardiovascular issues following a concussion, the researchers examined medical records of previously healthy patients treated for TBI between 2000 and 2015 who also had at least 1 follow-up visit between 6 months and 10 years after the initial injury.

Researchers analyzed data from 13,053 individuals – 4,351 with mild injury (mTBI), 4351 with moderate to severe injury (msTBI), and 4351 with no TBI. The most common cause of injury was a fall. Patients with sports-related injuries were excluded.

Incidence of hypertension was significantly higher among patients with mTBI (hazard ratio, 2.5; 95% confidence interval, 2.1-2.9) and msTBI (HR, 2.4; 95% CI, 2.0-2.9), compared with the unaffected group. Risk for other cardiovascular problems, including hyperlipidemia, obesity, and coronary artery disease, were also higher in the affected groups.

TBI patients also reported higher incidence of endocrine diseases, including diabetes (mTBI: HR, 1.9; 95% CI, 1.4-2.7; msTBI: HR, 1.9; 95% CI, 1.4-2.6). Elevated risk for ischemic stroke or transient ischemic attack was also increased (mTBI: HR, 2.2; 95% CI, 1.4-3.3; msTBI: HR, 3.6; 95% CI, 2.4-5.3).

Regardless of injury severity, patients with TBI had a higher risk for neurologic and psychiatric diseases, particularly depression, dementia, and psychotic disorders. “This tells us that mild TBI is not clean of events,” Dr. Zafonte said.

Surprising rate of comorbidity in youth

Investigators found increased risk for posttrauma comorbidities in all age groups, but researchers were struck by the high rates in younger patients, aged 18-40. Compared with age-matched individuals with no TBI history, hypertension risk was nearly six times higher in those with mTBI (HR, 5.9; 95% CI, 3.9-9.1) and nearly four times higher in patients with msTBI (HR, 3.9; 95% CI, 2.5-6.1).

Rates of hyperlipidemia and diabetes were also higher in younger patients in the mTBI group and posttraumatic seizures and psychiatric disorders were elevated regardless of TBI severity.

Overall, patients with msTBI, but not those with mTBI, were at higher risk for mortality, compared with the unexposed group (432 deaths [9.9%] vs. 250 deaths [5.7%]; P < .001).

“It’s clear that what we may be dealing with is that it holds up even for the younger people,” Dr. Zafonte said. “We used to think brain injury risk is worse in the severe cases, which it is, and it’s worse later on among those who are older, which it is. But our younger folks don’t get away either.”

While the study offers associations between TBI and multisystem health problems, Dr. Zafonte said it’s impossible to say at this point whether the brain injury caused the increased risk for cardiovascular or endocrine problems. Other organ injuries sustained in the trauma may be a contributing factor.

“Further data is needed to elucidate the mechanism and the causative relationships, which we do not have here,” he said.

Many of the postinjury comorbidities emerged a median of 3.5 years after TBI, regardless of severity. But some of the cardiovascular and psychiatric conditions emerged far sooner than that.

That’s important because research suggests less than half of patients with TBI receive follow-up care.

“It does make sense for folks who are interacting with people who’ve had a TBI to be suspicious of medical comorbidities relatively early on, within the first couple of years,” Dr. Zafonte said.

In an invited commentary, Vijay Krishnamoorthy, MD, MPH, PhD, Duke University, Durham, N.C., and Monica S. Vavilala, MD, University of Washington, Seattle, highlight some of the study’s limitations, including a lack of information on comorbidity severity and the lack of a matched group of patients who experienced non-head trauma.

Despite those limitations, the study offers important information on how TBI may affect organs beyond the brain, they noted.

“These observations, if replicated in future studies, raise intriguing implications in the future care of patients with TBI, including heightened chronic disease-screening measures and possibly enhanced guidelines for chronic extracranial organ system care for patients who experience TBI,” Dr. Krishnamoorthy and Dr. Vavilala wrote.

The study received no specific funding. Dr. Zafonte reported having received personal fees from Springer/Demos, serving on scientific advisory boards for Myomo and OnCare and has received funding from the Football Players Health Study at Harvard, funded in part by the National Football League Players Association. Dr. Krishnamoorthy and Dr. Vavilala disclosed no relevant financial relationships.

More than half of patients taking the two highest doses of tirzepatide as a once-weekly injection lost at least 20% of their body weight in the first phase 3 trial to examine this agent in patients with obesity, but without diabetes, according to preliminary top-line results from the SURMOUNT-1 trial announced by Lilly.  

The full results will be reported at an upcoming medical conference and published at a later date, Lilly added.

There was much excitement in response to the news, but others have urged caution and noted that, even if tirzepatide is eventually approved for obesity, one of the major barriers to use in the United States will be insurance coverage.

“Wow (and a double Wow!) 52lb weight loss (22.5%) at highest dose of tirzepatide,” tweeted Sek Kathiresan, MD, a cardiologist who is cofounder of Verve Therapeutics and on leave from Harvard (@skathire).

“Thus far the challenge with GLP-1s [agonists] for management of obesity is that insurance usually isn’t covering them. This makes them unaffordable for most people,” replied James Marroquin, MD, of the University of Texas at Austin. (@Jamesmarroquin).

Yoni Freedhoff, MD, of the University of Ottawa (Ont.) who writes a column for this news organization on obesity, said if tirzepatide pans out, along with other similar agents already on the market for this indication, “the next few decades should see the pharmaceutical management of obesity rival its surgical management.”

Would compete with ‘game-changer’ semaglutide?

Tirzepatide has been dubbed a “twincretin” because it works not only as an agonist of the glucagonlike peptide-1 (GLP-1) receptor, but also of the glucose-dependent insulinotropic polypeptide (GIP) receptor. It has been much hyped based on the results of the series of SURPASS clinical trials, which have formed the basis of the application for type 2 diabetes approval, about which the U.S. Food and Drug Administration is expected to make a decision soon.

Several GLP-1 agonists are on the market for both type 2 diabetes and for obesity indications separately, including semaglutide (marketed as Wegovy for obesity, also a once-weekly injection) and liraglutide (Saxenda for obesity, a daily injection), both Novo Nordisk agents.

Wegovy was approved for weight loss in the United States last year, with doctors telling this news organization then that a third of patients who take the drug are likely to lose 20% or more of their starting weight, an outcome that approaches reductions seen with bariatric surgery.

Dr. Freedhoff said he’d like to see “reimbursement by insurers who will see these drugs serving as important ancillary treatments for the myriad of weight-responsive conditions they’re already covering.”

SURMOUNT-1 data: ‘Impressive body weight’ reductions

The new tirzepatide data come from the multicenter, randomized, double-blind, placebo-controlled SURMOUNT-1 trial, which included 2539 participants from the United States, Argentina, Brazil, China, India, Japan Mexico, Russia, and Taiwan. They had obesity or overweight plus at least one comorbidity but not diabetes. They were randomized to 5-mg, 10-mg, or 15-mg once-weekly tirzepatide or placebo injections for 18 months (72 weeks).

Efficacy was analyzed in two ways. Prior to factoring in drug discontinuation, participants taking tirzepatide experienced weight loss of 16.0% (35 lb/16 kg) with 5 mg, 21.4% (49 lb/22 kg) with 10 mg, and 22.5% (52 lb/24 kg) on 15 mg. In contrast, the placebo group lost just 2.4% of body weight (5 lb/2 kg).  

But treatment discontinuation rates because of adverse events were 4.3%, 7.1%, 6.2%, and 2.6%, for tirzepatide 5 mg, 10 mg, 15 mg, and placebo, respectively. Overall treatment discontinuation rates were 14.3%, 16.4%, 15.1%, and 26.4%, respectively.  

When efficacy was assessed regardless of treatment discontinuation, average body weight reductions were 15.0%, 19.5%, 20.9%, and 3.1% for tirzepatide 5 mg, 10 mg, 15 mg, and placebo, respectively.  

More than half of patients taking tirzepatide 10 mg and 15 mg (55% and 63%, respectively) lost at least 20% of their body weight, compared with just 1.3% taking placebo.

Overall safety and tolerability were similar to those of other GLP-1 agonists, with adverse events being gastrointestinal in nature and increasing with higher doses. Nausea affected 24.6%, 33.3%, and 31.0% of the tirzepatide 5-mg, 10-mg, and 15-mg dose groups, respectively, and vomiting was experienced by 8.3%, 10.7%, and 12.2% of patients, respectively. Diarrhea and constipation were also reported more often with the drug than placebo.

“Tirzepatide delivered impressive body weight reductions in SURMOUNT-1, which could represent an important step forward for helping the patient and physician partnership treat this complex disease,” said study investigator Louis J. Aronne, MD, director of the Comprehensive Weight Control Center and the Sanford I. Weill Professor of Metabolic Research at Weill Cornell Medicine, New York, in a press release.

Further studies are ongoing for tirzepatide as a potential treatment for obesity or overweight, according to the Lilly statement. SURMOUNT is a phase 3 global clinical development program for tirzepatide that began in late 2019 with over 5,000 people with obesity or overweight across six clinical trials. Results from SURMOUNT-2, SURMOUNT-3, and SURMOUNT-4 are expected in 2023.

Tirzepatide is also being studied as a potential treatment for nonalcoholic fatty liver disease and heart failure with preserved ejection fraction. Studies of tirzepatide in obstructive sleep apnea and of morbidity/mortality in obesity are also planned.

Dr. Aronne is cofounder, chief scientific advisor, and a member of the board of directors for Intellihealth. He is also a paid scientific advisory board member for Eli Lilly. Dr. Freedhoff has served or is serving as a director, officer, partner, employee, adviser, consultant, or trustee for the Bariatric Medical Institute and Constant Health and has received a research grant from Novo Nordisk.

More than half of patients taking the two highest doses of tirzepatide as a once-weekly injection lost at least 20% of their body weight in the first phase 3 trial to examine this agent in patients with obesity, but without diabetes, according to preliminary top-line results from the SURMOUNT-1 trial announced by Lilly.  

The full results will be reported at an upcoming medical conference and published at a later date, Lilly added.

There was much excitement in response to the news, but others have urged caution and noted that, even if tirzepatide is eventually approved for obesity, one of the major barriers to use in the United States will be insurance coverage.

In the placebo-controlled REDUCE-IT trial, icosapent ethyl (IPE) was linked to a significant reduction in major adverse cardiovascular events (MACE) when administered on top of LDL cholesterol control, but a new substudy suggests a greater relative advantage in those with a prior myocardial infarction.

In the study as a whole, IPE (Vascepa, Amarin) was tied to a 20% reduction in CV death (hazard ratio, 0.80; P = .03), but it climbed to a 30% reduction (HR, 0.70; P = .01) in the subgroup with a prior MI, reported a multinational team of investigators led by Prakriti Gaba, MD, a cardiologist at Brigham and Women’s Hospital, Boston.

On the basis of these data, “the imperative to treat patients who have a history of prior MI is even stronger,” said Deepak L. Bhatt, MD, executive director of interventional cardiovascular programs at Brigham and Women’s Hospital.

The principal investigator of REDUCE-IT and a coauthor of this subanalysis, Dr. Bhatt said in an interview, “The significant reduction in cardiovascular mortality, as well as sudden cardiac death and cardiac arrest, really should make physicians strongly consider this therapy in eligible patients.”

The main results of the REDUCE-IT trial were published more than 3 years ago. It enrolled patients with established CV disease or diabetes with additional risk factors who were on a statin and had elevated triglyceride (TG) levels.

A 25% reduction in MACE reported

In those randomized to IPE, there was about a 25% reduction in the primary composite MACE outcome of cardiovascular death, nonfatal MI, nonfatal stroke, revascularization, and unstable angina relative to placebo. About the same relative reduction was achieved in the key secondary endpoint of CV death, nonfatal MI, and nonfatal stroke.

Some guidelines have been changed on the basis of these data. The National Lipid Association, for example, conferred a class 1 recommendation for adding IPE to other appropriate lipid-reducing therapies in any individual 45 years of age or older with atherosclerotic cardiovascular disease.

This new substudy (J Am Coll Cardiol. 2022 Apr 25; doi: 10.1016/j.jacc.2022.02.035), is likely to be influential for those guidelines not yet revised. In the substudy of the prior MI patients, the relative benefit of IPE for the primary and secondary MACE endpoints were of similar magnitude to the overall study population, but events occurred more frequently in the prior-MI subgroup, greatly increasing the statistical power of the advantage.


 

More MACE in prior MI patients

For example, the primary outcome was observed in 22% of the placebo patients in the overall REDUCE-IT analysis but in 26.1% of those with prior MI, so even though the relative risk reduction remained at about 25%, the statistical strength was a hundred-fold greater (P = .00001 vs. P < .001).

For the key secondary composite MACE endpoint, the relative reduction for those with a prior MI was modestly greater than the study as a whole (HR 0.71 vs. HR. 075) but the statistical strength was again magnified in those with a prior MI (P = .00006 vs. P < .001). In those with a prior MI , the advantage of receiving IPE was similar whether or not there had been a prior revascularization.

The 20% lower rate of all-cause mortality among prior MI patients receiving IPE rather than placebo fell just short of statistical significance (HR, 0.80; P = .054). Ischemic events on IPE were reduced by 35% (P = .0000001) and recurrent MI was reduced by 34% (P = .00009).

In the substudy as well as in the REDUCE-IT trial overall, IPE was well tolerated. A slightly higher rate of atrial fibrillation was reported in both.

The REDUCE-IT substudy evaluated 3,693 patients with a history of MI, representing 45% of the 8,179 patients randomized.

IPE, an ethyl ester of the omega-3 polyunsaturated fatty acid, initially attracted attention for its ability to reduce elevated TG. It was hoped this would address reduce residual risk in patients on maximally reduced LDL cholesterol. However, it is suspected that IPE exerts benefits additive to or independent of TG lowering, according to the authors of the REDUCE-IT substudy. These include attenuation of the inflammatory response, release of nitric oxide, and effects that support stabilization of atherosclerotic plaque.

The investigators reported that the pattern of response supports this theory. In the newly reported substudy, the primary event curves that included nonthrombotic events separated at about 1 year, but even curves for CV death and sudden cardiac death were more delayed.

This delay might be explained “by the slow but steady reduction in plaque volume, mitigation of inflammation, improvements in endothelial function, and membrane stabilization,” according to the authors, who cited studies suggesting each of these effects might not be wholly dependent on TG reductions alone.
 

Prior TG-lowering studies disappointing

In fact, several studies evaluating other strategies for TG reductions have been disappointing, according to an accompanying editorial (J Am Coll Cardiol. 2022 Apr 25; doi: 10.1016/j.jacc.2022.03.001). For example, the STRENGTH trial did not show clinical benefits despite a slightly greater reduction in TGs than that shown in REDUCE-IT (19% reduction vs. 18.3%).

Overall, the REDUCE-IT trial and the prior-MI REDUCE-IT substudy show that there is targetable residual risk in high risk patients on statin therapy. One of the authors of the editorial that accompanied the prior-MI substudy of REDUCE-IT, William E. Boden, MD, professor of medicine, Boston University, emphasized this point. On the basis of REDUCE-IT, he said he believes that IPE should be considered to have broad indications as an adjunctive treatment to other lipid-lowering strategies.

“My practice centers on optimizing secondary prevention in high-risk patients who have elevated TG levels despite well-controlled LDL levels on statins, ezetimibe, or even PCSK-9 [proprotein convertase subtilisin/kexin type 9] inhibitors,” Dr. Boden said in an interview. Patients with diabetes are notorious for presenting with this profile of dyslipidemia, but he added that “even nondiabetics with prior MI, acute coronary syndrome, or revascularization will benefit from the addition of IPE to high-potency statins.”

Although the American Heart Association and the American College of Cardiology have not yet updated their guidelines to include IPE, Dr. Boden pointed out that the European Society of Cardiology, the Canadian Cardiovascular Society, and the American Diabetes Society have.

Dr. Bhatt added that there is a clear message from REDUCE-IT that IPE addresses residual risk.

Targeting the subgroup of high-risk patients with elevated TGs “is easy” because they are so readily identifiable, according to Dr. Bhatt, but he said it should be used for any patient that meet the entry criteria used for REDUCE-IT.

“The overall results of REDUCE-IT were robustly positive, so I wouldn’t just use it in patients with prior MI,” Dr. Bhatt said.

Dr. Bhatt reports financial relationships with more than 20 pharmaceutical companies, including Amarin, which provided funding for this trial. Dr. Boden reports no potential conflicts of interest.

The principal investigator of REDUCE-IT and a coauthor of this subanalysis, Dr. Bhatt said in an interview, “The significant reduction in cardiovascular mortality, as well as sudden cardiac death and cardiac arrest, really should make physicians strongly consider this therapy in eligible patients.”

The main results of the REDUCE-IT trial were published more than 3 years ago. It enrolled patients with established CV disease or diabetes with additional risk factors who were on a statin and had elevated triglyceride (TG) levels.

A 25% reduction in MACE reported

In those randomized to IPE, there was about a 25% reduction in the primary composite MACE outcome of cardiovascular death, nonfatal MI, nonfatal stroke, revascularization, and unstable angina relative to placebo. About the same relative reduction was achieved in the key secondary endpoint of CV death, nonfatal MI, and nonfatal stroke.

Some guidelines have been changed on the basis of these data. The National Lipid Association, for example, conferred a class 1 recommendation for adding IPE to other appropriate lipid-reducing therapies in any individual 45 years of age or older with atherosclerotic cardiovascular disease.

This new substudy (J Am Coll Cardiol. 2022 Apr 25; doi: 10.1016/j.jacc.2022.02.035), is likely to be influential for those guidelines not yet revised. In the substudy of the prior MI patients, the relative benefit of IPE for the primary and secondary MACE endpoints were of similar magnitude to the overall study population, but events occurred more frequently in the prior-MI subgroup, greatly increasing the statistical power of the advantage.


 

More MACE in prior MI patients

For example, the primary outcome was observed in 22% of the placebo patients in the overall REDUCE-IT analysis but in 26.1% of those with prior MI, so even though the relative risk reduction remained at about 25%, the statistical strength was a hundred-fold greater (P = .00001 vs. P < .001).

For the key secondary composite MACE endpoint, the relative reduction for those with a prior MI was modestly greater than the study as a whole (HR 0.71 vs. HR. 075) but the statistical strength was again magnified in those with a prior MI (P = .00006 vs. P < .001). In those with a prior MI , the advantage of receiving IPE was similar whether or not there had been a prior revascularization.

The 20% lower rate of all-cause mortality among prior MI patients receiving IPE rather than placebo fell just short of statistical significance (HR, 0.80; P = .054). Ischemic events on IPE were reduced by 35% (P = .0000001) and recurrent MI was reduced by 34% (P = .00009).

In the substudy as well as in the REDUCE-IT trial overall, IPE was well tolerated. A slightly higher rate of atrial fibrillation was reported in both.

The REDUCE-IT substudy evaluated 3,693 patients with a history of MI, representing 45% of the 8,179 patients randomized.

IPE, an ethyl ester of the omega-3 polyunsaturated fatty acid, initially attracted attention for its ability to reduce elevated TG. It was hoped this would address reduce residual risk in patients on maximally reduced LDL cholesterol. However, it is suspected that IPE exerts benefits additive to or independent of TG lowering, according to the authors of the REDUCE-IT substudy. These include attenuation of the inflammatory response, release of nitric oxide, and effects that support stabilization of atherosclerotic plaque.

The investigators reported that the pattern of response supports this theory. In the newly reported substudy, the primary event curves that included nonthrombotic events separated at about 1 year, but even curves for CV death and sudden cardiac death were more delayed.

This delay might be explained “by the slow but steady reduction in plaque volume, mitigation of inflammation, improvements in endothelial function, and membrane stabilization,” according to the authors, who cited studies suggesting each of these effects might not be wholly dependent on TG reductions alone.
 

Prior TG-lowering studies disappointing

In fact, several studies evaluating other strategies for TG reductions have been disappointing, according to an accompanying editorial (J Am Coll Cardiol. 2022 Apr 25; doi: 10.1016/j.jacc.2022.03.001). For example, the STRENGTH trial did not show clinical benefits despite a slightly greater reduction in TGs than that shown in REDUCE-IT (19% reduction vs. 18.3%).

Overall, the REDUCE-IT trial and the prior-MI REDUCE-IT substudy show that there is targetable residual risk in high risk patients on statin therapy. One of the authors of the editorial that accompanied the prior-MI substudy of REDUCE-IT, William E. Boden, MD, professor of medicine, Boston University, emphasized this point. On the basis of REDUCE-IT, he said he believes that IPE should be considered to have broad indications as an adjunctive treatment to other lipid-lowering strategies.

“My practice centers on optimizing secondary prevention in high-risk patients who have elevated TG levels despite well-controlled LDL levels on statins, ezetimibe, or even PCSK-9 [proprotein convertase subtilisin/kexin type 9] inhibitors,” Dr. Boden said in an interview. Patients with diabetes are notorious for presenting with this profile of dyslipidemia, but he added that “even nondiabetics with prior MI, acute coronary syndrome, or revascularization will benefit from the addition of IPE to high-potency statins.”

Although the American Heart Association and the American College of Cardiology have not yet updated their guidelines to include IPE, Dr. Boden pointed out that the European Society of Cardiology, the Canadian Cardiovascular Society, and the American Diabetes Society have.

Dr. Bhatt added that there is a clear message from REDUCE-IT that IPE addresses residual risk.

Targeting the subgroup of high-risk patients with elevated TGs “is easy” because they are so readily identifiable, according to Dr. Bhatt, but he said it should be used for any patient that meet the entry criteria used for REDUCE-IT.

“The overall results of REDUCE-IT were robustly positive, so I wouldn’t just use it in patients with prior MI,” Dr. Bhatt said.

Dr. Bhatt reports financial relationships with more than 20 pharmaceutical companies, including Amarin, which provided funding for this trial. Dr. Boden reports no potential conflicts of interest.

Although lipoprotein(a) is causally related to coronary artery disease and aortic valve stenosis – two known risk factors for atrial fibrillation (AFib) – evidence linking Lp(a) to a causal role in the development of AFib has been lukewarm at best.

A recent Mendelian randomization study showed only a nominally significant effect of Lp(a) on AFib, whereas an ARIC substudy showed high levels of Lp(a) to be associated with elevated ischemic stroke risk but not incident AFib.

A new study that adds the heft of Mendelian randomization to large observational and genetic analyses, however, implicates Lp(a) as a potential causal mediator of AFib, independent of its known effects on atherosclerotic cardiovascular disease (ASCVD).

“Why this is exciting is because it shows that Lp(a) has effects beyond the arteries and beyond the aortic valve, and that provides two things,” senior author Guillaume Paré, MD, MSc, Population Health Research Institute, Hamilton, Ontario, told this news organization.

“First, it provides a potential means to decrease the risk, because there are all these Lp(a) inhibitors in development,” he said. “But I think the other thing is that it just points to a new pathway that leads to atrial fibrillation development that could potentially be targeted with other drugs when it’s better understood. We don’t pretend that we understand the biology there, but it opens this possibility.”

The results were published in the Journal of the American College of Cardiology.

Using data from 435,579 participants in the UK Biobank, the researchers identified 20,432 cases of incident AFib over a median of 11 years of follow-up. They also constructed a genetic risk score for Lp(a) using genetic variants within 500 kb of the LPA gene.

After common AFib risk factors were controlled for, results showed a 3% increased risk for incident AFib per 50 nmol/L increase in Lp(a) at enrollment (hazard ratio, 1.03; 95% confidence interval, 1.02-1.05).

A Mendelian randomization analysis showed a similar association between genetically predicted Lp(a) and AFib (odds ratio, 1.03; 95% CI, 1.02-1.05).

To replicate the results, the investigators performed separate Mendelian randomization analyses using publicly available genome-wide association study (GWAS) statistics from the largest GWAS of AFib involving more than 1 million participants and from the FinnGen cohort involving more than 114,000 Finnish residents.

The analyses showed a 3% increase in risk for AFib in the genome-wide study (OR, 1.03; 95% CI, 1.02-1.05) and an 8% increase in risk in the Finnish study (OR, 1.08; 95% CI, 1.04-1.12) per 50 nmol/L increase in Lp(a).

There was no evidence that the effect of observed or genetically predicted Lp(a) was modified by prevalent ischemic heart disease or aortic stenosis.

Further, MR analyses revealed no risk effect of low-density-lipoprotein cholesterol or triglycerides on AFib.

Notably, only 39% of Lp(a) was mediated through ASCVD, suggesting that Lp(a) partly influences AFib independent of its known effect on ASCVD.

“To me, the eureka moment is when we repeated the same analysis for LDL cholesterol and it had absolutely no association with AFib,” Dr. Paré said. “Because up to that point, there was always this lingering doubt that, well, it’s because of coronary artery disease, and that’s logical. But the signal is completely flat with LDL, and we see this strong signal with Lp(a).”

Another ‘red flag’

Erin D. Michos, MD, MHS, senior author of the ARIC substudy and associate director of preventive cardiology at Johns Hopkins School of Medicine, Baltimore, said the findings are “another red flag that lipoprotein(a) is a marker we need to pay attention to and potentially needs treatment.”

“The fact that it was Mendelian randomization does suggest that there’s a causal role,” she said. “I think the relationship is relatively modest compared to its known risk for stroke, ASCVD, coronary disease, and aortic stenosis, ... which may be why we didn’t see it in the ARIC cohort with 12,000 participants. You needed to have a million participants and 60,000 cases to see an effect here.”

Dr. Michos said she hopes the findings encourage increased testing, particularly with multiple potential treatments currently in the pipeline. She pointed out that the researchers estimated that the experimental antisense agent pelacarsen, which lowers Lp(a) by about 80%, would translate into about an 8% reduction in AFib risk, or “the same effect as 2 kg of weight loss or a 5 mm Hg reduction in blood pressure, which we do think are meaningful.”

Adding to this point in an accompanying editorial, Daniel Seung Kim, MD, PhD, and Abha Khandelwal, MD, MS, Stanford University School of Medicine, California, say that “moreover, reduction of Lp(a) levels would have multifactorial effects on CAD, cerebrovascular/peripheral artery disease, and AS risk.

“Therefore, approaches to reduce Lp(a) should be prioritized to further reduce the morbidity and mortality of a rapidly aging population,” they write.

The editorialists also join the researchers in calling for inclusion of AFib as a secondary outcome in ongoing Lp(a) trials, in addition to cerebrovascular disease and peripheral vascular disease.
 

Unanswered questions

As to what’s driving the risk effect of Lp(a), first author Pedrum Mohammadi-Shemirani, PhD, also from the Population Health Research Institute, explained that in aortic stenosis, “mechanical stress increases endothelial permeability, allowing Lp(a) to infiltrate valvular tissue and induce gene expression that results in microcalcifications and cell death.”

“So, in theory, a similar sort of mechanism could be at play in atrial tissue that may lead to damage and the electrical remodeling that causes atrial fibrillation,” he told this news organization.

Dr. Mohammadi-Shemirani also noted that Lp(a) has proinflammatory properties, but added that any potential mechanisms are “speculative and require further research to disentangle.”

Dr. Paré and colleagues say follow-up studies are also warranted, noting that generalizability of the results may be limited because AFib cases were found using electronic health records in the population-scale cohorts and because few UK Biobank participants were of non-European ancestry and Lp(a) levels vary among ethnic groups.

Another limitation is that the number of kringle IV type 2 domain repeats within the LPA gene, the largest contributor to genetic variation in Lp(a), could not be directly measured. Still, 71.4% of the variation in Lp(a) was explained using the genetic risk score alone, they say.

Bariatric surgery can reduce the risk of long-term cardiovascular outcomes in older Medicare beneficiaries with obesity, a large new observational study in which a third of the patients were over age 65 years suggests.

Overall, patients who underwent bariatric surgery had 37% lower all-cause mortality and were significantly less likely to have admissions for new-onset heart failure (64% risk reduction), myocardial infarction (37% risk reduction), and ischemic stroke (29% risk reduction), compared with similar patients who received more conservative treatment, after a median of 4 years of follow-up, report Amgad Mentias, MD, MS, a clinical cardiologist at the Cleveland Clinic Foundation, Ohio, and colleagues.

The results were published in the Journal of the American College of Cardiology.

Previous studies on bariatric surgery outcomes have primarily focused on individuals from select health care networks or medical facilities with restricted coverage in the United States or on patients with diabetes, noted Tiffany M. Powell-Wiley, MD, MPH, of the National Institutes of Health’s National Heart, Lung, and Blood Institute, Bethesda, Maryland, and colleagues in an accompanying editorial.

Contemporary cohort of patients

“A lot of the studies showed long-term outcomes outside of the U.S., specifically in Europe,” Dr. Mentias added.

The aim of this study was to evaluate the long-term association between bariatric surgery and risk of adverse cardiovascular outcomes in a contemporary large cohort from the United States.

Older patients (> 65 years) and those without diabetes were looked at as specific subgroups.

The researchers assessed 189,770 patients. There were 94,885 matched patients in each cohort. Mean age was 62.33 years. Female patients comprised 70% of the cohort. The study group had an average BMI of 44.7 kg/m2.

The study cohort was matched 1:1. Participants were either part of a control group with obesity or a group of Medicare beneficiaries who had bariatric surgery between 2013 and 2019. Sex, propensity score matching on 87 clinical variables, age, and BMI were used to match patients.

Myocardial infarction, new-onset heart failure, ischemic stroke, and all-cause mortality were all study outcomes. As a sensitivity analysis, the study team conducted an instrumental variable assessment.

More specifically, the findings showed that bariatric surgery was linked with the following after a median follow-up of 4.0 years:

• Myocardial infarction (hazard ratio, 0.63; 95% confidence interval, 0.59-0.68)
• Stroke (HR, 0.71; 95% CI, 0.65-0.79)
• New-onset heart failure (HR, 0.46; 95% CI, 0.44-0.49)
• Reduced risk of death (9.2 vs. 14.7 per 1000 person-years; HR, 0.63; 95% CI, 0.60-0.66)

Findings for those over the age of 65 were similar – lower risks of all-cause mortality (HR, 0.64), new-onset heart failure (HR, 0.52), myocardial infarction (HR, 0.70), and stroke (HR, 0.76; all P < .001). Similar findings were shown in subgroup analyses in men and women and in patients with and without diabetes.

The study cohort primarily consisted of Medicare patients, which limits the generalizability of the data. Lack of data on medications taken for cardiovascular and weight loss purposes and potential coding errors because the information was gathered from an administrative database were all limitations of the study, the researchers note.

An additional limitation was that residual unmeasured confounders, particularly patient-focused physical, social, and mental support factors, could play a role in whether a patient opted to have bariatric surgery, the study authors note.

“Additional studies are needed to compare cardiovascular outcomes after bariatric surgery with weight loss medications like glucagon-like peptide-1 (GLP-1) analogues,” the researchers add.

This study was partially funded by philanthropic contributions by the Khouri family, Bailey family, and Haslam family to the Cleveland Clinic for co-author Dr. Milind Y. Desai’s research. Dr. Mentias has disclosed no relevant financial relationships. Dr. Powell-Wiley disclosed relationships with the National Institute on Minority Health and Health Disparities and the Division of Intramural Research of the National, Heart, Lung, and Blood Institute of the National Institutes of Health.

“A lot of the studies showed long-term outcomes outside of the U.S., specifically in Europe,” Dr. Mentias added.

The aim of this study was to evaluate the long-term association between bariatric surgery and risk of adverse cardiovascular outcomes in a contemporary large cohort from the United States.

Older patients (> 65 years) and those without diabetes were looked at as specific subgroups.

The researchers assessed 189,770 patients. There were 94,885 matched patients in each cohort. Mean age was 62.33 years. Female patients comprised 70% of the cohort. The study group had an average BMI of 44.7 kg/m2.

The study cohort was matched 1:1. Participants were either part of a control group with obesity or a group of Medicare beneficiaries who had bariatric surgery between 2013 and 2019. Sex, propensity score matching on 87 clinical variables, age, and BMI were used to match patients.

Myocardial infarction, new-onset heart failure, ischemic stroke, and all-cause mortality were all study outcomes. As a sensitivity analysis, the study team conducted an instrumental variable assessment.

More specifically, the findings showed that bariatric surgery was linked with the following after a median follow-up of 4.0 years:

• Myocardial infarction (hazard ratio, 0.63; 95% confidence interval, 0.59-0.68)
• Stroke (HR, 0.71; 95% CI, 0.65-0.79)
• New-onset heart failure (HR, 0.46; 95% CI, 0.44-0.49)
• Reduced risk of death (9.2 vs. 14.7 per 1000 person-years; HR, 0.63; 95% CI, 0.60-0.66)

Findings for those over the age of 65 were similar – lower risks of all-cause mortality (HR, 0.64), new-onset heart failure (HR, 0.52), myocardial infarction (HR, 0.70), and stroke (HR, 0.76; all P < .001). Similar findings were shown in subgroup analyses in men and women and in patients with and without diabetes.

The study cohort primarily consisted of Medicare patients, which limits the generalizability of the data. Lack of data on medications taken for cardiovascular and weight loss purposes and potential coding errors because the information was gathered from an administrative database were all limitations of the study, the researchers note.

An additional limitation was that residual unmeasured confounders, particularly patient-focused physical, social, and mental support factors, could play a role in whether a patient opted to have bariatric surgery, the study authors note.

“Additional studies are needed to compare cardiovascular outcomes after bariatric surgery with weight loss medications like glucagon-like peptide-1 (GLP-1) analogues,” the researchers add.

This study was partially funded by philanthropic contributions by the Khouri family, Bailey family, and Haslam family to the Cleveland Clinic for co-author Dr. Milind Y. Desai’s research. Dr. Mentias has disclosed no relevant financial relationships. Dr. Powell-Wiley disclosed relationships with the National Institute on Minority Health and Health Disparities and the Division of Intramural Research of the National, Heart, Lung, and Blood Institute of the National Institutes of Health.

Bariatric surgery can reduce the risk of long-term cardiovascular outcomes in older Medicare beneficiaries with obesity, a large new observational study in which a third of the patients were over age 65 years suggests.

Overall, patients who underwent bariatric surgery had 37% lower all-cause mortality and were significantly less likely to have admissions for new-onset heart failure (64% risk reduction), myocardial infarction (37% risk reduction), and ischemic stroke (29% risk reduction), compared with similar patients who received more conservative treatment, after a median of 4 years of follow-up, report Amgad Mentias, MD, MS, a clinical cardiologist at the Cleveland Clinic Foundation, Ohio, and colleagues.

The results were published in the Journal of the American College of Cardiology.

Previous studies on bariatric surgery outcomes have primarily focused on individuals from select health care networks or medical facilities with restricted coverage in the United States or on patients with diabetes, noted Tiffany M. Powell-Wiley, MD, MPH, of the National Institutes of Health’s National Heart, Lung, and Blood Institute, Bethesda, Maryland, and colleagues in an accompanying editorial.
