Cardiac arrest during long-distance running races

JAMA

2025-03-30

(Press-News.org) About The Study: This study found that despite increased participation in U.S. long distance running races, the incidence of cardiac arrest during U.S. marathons and half-marathons remains stable. There has been a marked decline in cardiac arrest mortality, and coronary artery disease was the most common etiology among cases with sufficient cause-related data. Effective emergency action planning with immediate access to defibrillation may explain the improvement in survival.

Preventable cardiac deaths during marathons are down, Emory study finds

2025-03-30

While more people than ever are running marathons in the U.S., the risk of dying from a heart attack during a run has fallen dramatically in recent years. That’s a key conclusion from a new study by Jonathan Kim, associate professor in the Emory School of Medicine. Kim’s research is a follow-up to a study he published in 2012 – the first investigation into unexpected cardiac arrests during long distance running events. The new findings, published in JAMA, indicate that while the rate of marathon runners who suffer cardiac arrests remained unchanged, their chance for survival is twice what it was in the ...

New study finds peripheral artery disease often underdiagnosed and undertreated; opportunity to improve treatments, lower death rates

2025-03-30

A new Intermountain Health study finds that peripheral artery disease, a condition that affects more than 10 million Americans over the age of 40, is often underdiagnosed and undertreated, with fewer women getting guideline-directed medical therapy than men. As a result, combined with this highly debilitating disease, patients with peripheral artery disease have a more than 50 percent chance of dying from the condition. Peripheral artery disease affects nearly 10 percent of the US population. It occurs when the arteries that carry blood to the legs and arms become narrowed or blocked by plaque ...

Use of antidepressant medication linked to substantial increase in risk of sudden cardiac death

2025-03-30

Vienna, Austria- 30 March 2025 Sudden cardiac death (SCD) refers to an unexpected death of a person, believed to be caused by a heart-related issue. It occurs within one hour of the onset of symptoms in witnessed cases or within 24 hours of the person being last seen alive in unwitnessed cases. The causes in people under the age of 39 are often a thickening of the heart muscle or an electrical problem with the heart. In older people, SCD is more likely to be caused by a narrowing of the blood vessels that supply the heart. Previous research has shown1 that patients with psychiatric disorders have an increased all-cause mortality ...

Atrial fibrillation diagnosed in midlife is linked to a 21% increased risk of dementia at any age and a 36% higher risk of early-onset dementia

2025-03-30

Vienna, Austria- 31 March 2025 New research presented at the EHRA 2025, a scientific congress of the European Society of Cardiology, shows that the presence of atrial fibrillation (AF) increases the risk of future dementia by 21% in patients diagnosed with AF under 70 and the risk of early-onset dementia (diagnosed before age 65 years) by 36%. The association was stronger in younger adults and was lost in older adults aged 70 years and over. “This is the largest European population-based study evaluating the association between AF and dementia,” say the authors that include Dr Julián Rodriguez ...

Mode of death in patients with heart failure with mildly reduced or preserved ejection fraction

2025-03-30

About The Study: Among patients with heart failure with mildly reduced ejection fraction/heart failure with preserved ejection fraction in the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure randomized clinical trial, higher proportions of cardiovascular and overall mortality in those with ejection fraction less than 50% were related principally to higher proportions of sudden death. A clear treatment effect of finerenone on cardiovascular or cause-specific mortality was not identified, although the trial was likely underpowered for these outcomes.

Intravenous ferric carboxymaltose in heart failure with iron deficiency

2025-03-30

About The Study: In patients with heart failure and iron deficiency, ferric carboxymaltose did not significantly reduce the time to first heart failure hospitalization or cardiovascular death in the overall cohort or in patients with a transferrin saturation less than 20%, or reduce the total number of heart failure hospitalizations vs placebo.

Artificial intelligence in the prevention of sudden death

2025-03-30

Many cases of sudden cardiac death could be avoided thanks to artificial intelligence. As part of a new study to be published in European Heart Journal, a network of artificial neurons imitating the human brain was developed by researchers from Inserm, Paris Cité University and the Paris public hospitals group (AP-HP), in collaboration with their colleagues in the USA. During the analysis of data from over 240 000 ambulatory electrocardiograms, this algorithm identified patients at risk of a serious arrhythmia that was capable of triggering cardiac arrest within the following 2 weeks in over 70% of cases. Each ...

Oral semaglutide vastly reduces heart attacks, strokes in people with type 2 diabetes

2025-03-29

Both the injectable and oral forms of semaglutide, a glucagon-like peptide-1 receptor agonist, have gained recent attention for their effectiveness against weight gain, high blood sugar, and even alcohol cravings. A new clinical trial, co-led by endocrinologist and diabetes expert John Buse, MD, PhD, and interventional cardiologist Matthew Cavender, MD, MPH, at the UNC School of Medicine has shown that the oral form of semaglutide can significantly reduce cardiovascular events in people with type 2 diabetes, atherosclerotic cardiovascular disease, and/or ...

Who needs a statin? New study compares prescribing recommendations based on traditional risk factors vs. coronary artery calcium scoring

2025-03-29

A new study by researchers at Intermountain Health in Salt Lake City aims to determine the best method to screen and evaluate patients who are at risk of developing coronary heart disease and which patients would benefit from taking a statin medication to lower cholesterol. Currently, cardiologists determine a patient’s need for a statin based on traditional risk factors, using the Pooled Cohort Equation (PCE), which calculates coronary risk by assessing the risk factors of age, sex, total and HDL cholesterol levels, blood pressure, and whether someone ...
