Mount Sinai researchers enhance AI tool to better detect heart disease risk

Mount Sinai researchers studying a type of heart disease known as hypertrophic cardiomyopathy (HCM) have calibrated an artificial intelligence (AI) algorithm to quickly and more specifically identify patients with the condition and flag them as high risk for greater attention during doctor's appointments.

Brisk walking linked to lower risk of heart rhythm disorders

A brisk walking pace, and the amount of time spent at this speed, may lower the risk of heart rhythm abnormalities, such as atrial fibrillation, tachycardia (rapid heartbeat), and bradycardia (very slow heartbeat), finds research published online in the journal Heart.

Early warning signs may help prevent sudden arrhythmic death syndrome

Recognizing and detecting the signs that commonly precede sudden arrhythmic death syndrome (SADS) may help to prevent premature deaths, according to research presented today at ESC Preventive Cardiology 2025, a scientific congress of the European Society of Cardiology (ESC).

Racial disparities persist in survival rates for young athletes with cardiac arrest

The overall survival rate of athletes who suffer sudden cardiac arrest has improved over the past decade, but the likelihood of surviving varies by race, where the cardiac arrest occurred and what athletes were doing when they collapsed, according to featured clinical research presented at the American College of Cardiology's Annual Scientific Session (ACC.25) and simultaneously published in JACC.

Antidepressant use associated with higher risk of sudden cardiac death in all age groups

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.

Atrial fibrillation elevates early-onset dementia risk in younger adults

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%.

New ESC consensus statement advances conduction system pacing therapy

The European Society of Cardiology (ESC) has released a groundbreaking consensus statement on conduction system pacing (CSP), marking a significant milestone in the evolution of pacing therapy.

New guidelines allow select athletes with heart abnormalities to participate in competitive sports

Recent research suggests that select athletes with cardiovascular abnormalities may be able to safely participate in competitive sports after shared decision-making with their clinicians about potential risks, according to a joint scientific statement published today in the American Heart Association's flagship, peer-reviewed journal Circulation and simultaneously in JACC, the flagship journal of the American College of Cardiology.

Black athletes face higher risk of sudden cardiac arrest and death

A recent major review of data published by the Lancet and led by Emory sports cardiologist Jonathan Kim, MD, shows that Black athletes are approximately five times more likely to experience sudden cardiac arrest (SCA) and sudden cardiac death (SCD) compared to White athletes, despite some evidence of a decline in rates of SCD overall.

Ablation may offer better outcomes than medication for ventricular tachycardia

Ablation, a procedure to treat abnormal electrical short circuits caused by a heart attack and is usually reserved for patients who do not improve with medication, may be a better first-line treatment for heart attack survivors experiencing dangerous rapid heartbeat episodes, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2024.
