A stem cell-based muscle patch improved heart pumping in a small study of advanced heart failure, offering an early clinical signal for regenerative cardiac therapy.

New research suggests persistent atrial fibrillation is not mainly a disease of the left atrium, but one that profoundly alters both upper chambers of the heart.

Researchers at Carnegie Mellon University and Cleveland Clinic built a domain-specific AI system that links cardiac MRI videos to radiology reports, allowing it to interpret scans without manually labeled training data.

Researchers say a deep learning model built from routine electrocardiograms can estimate 10-year stroke risk using only ECG data plus age and sex, with results comparable to an established clinical score.

Researchers at Ben-Gurion University say semaglutide and colchicine protect the heart through different mechanisms after injury, offering a clearer picture of how existing drugs might help prevent atrial fibrillation

A 1,001-patient randomized trial found low-dose digoxin did not significantly reduce the main composite endpoint in heart failure, though event counts trended lower than placebo.

A Samsung-backed clinical study suggests the Galaxy Watch 6 may be able to detect patterns linked to common fainting episodes before they happen, though researchers and clinicians still face major questions about false.

Researchers report that an AI system interpreting standard electrocardiograms accurately identified a major precursor to heart failure in Kenyan patients, pointing to a lower-cost screening option where echocardiography,

A systematic review and network meta-analysis of 37 studies found high-intensity interval exercise produced the strongest and most consistent improvements in endothelial function among cardiovascular patients.

A new blueprint argues that faster-moving cardiac implant technology now requires a more holistic approach to lead management and patient safety across the full life of a device.

A STAT News report highlights mouse research suggesting the heart’s constant mechanical stress may help explain why cancers in the organ are rare.

A late-breaking presentation at EHRA 2026 says left bundle branch area pacing is an effective and practical option for cardiac resynchronization, with the potential to reduce repeat surgeries and shorten implant times.

A presentation at EHRA 2026 reports that heart failure is common among people whose atrial fibrillation is detected during screening, highlighting the broader clinical burden that can accompany newly found rhythm disease

A placebo-controlled trial found that reopening a chronically blocked coronary artery with angioplasty reduced chest pain and improved quality of life, giving rare randomized evidence in a debated area of heart care.
