Credit: Nature (2026). DOI: 10.1038/s41586-025-10091-1 Atrial fibrillation is a common heart condition characterized by a rapid, irregular heartbeat stemming from the heart’s upper chamber. It is […]

Lois Anzelowitz Levine, MA January 27, 2026 A new study has found that wearable technology may be catching up to, or in some ways surpassing, standard care for cardiac event detection. The EQUAL trial, which was recently published in the Journal of the American College of Cardiology, showed smartwatches equipped with photoplethysmography (PPG) and ECG proved better at detecting episodes

Announcing a new article publication for Cardiovascular Innovations and Applications journal. This study investigated the association between serum uric acid (UA) levels and atrial fibrillation (AF) burden in Chinese patients with AF. In this cross-sectional study, AF burden was defined as the proportion of AF duration to total monitoring time, recorded by a patch device over ≥24

Ted Bosworth June 26, 2025 SAN DIEGO — Building on the success of a growing number of devices employing pulsed field ablation to control treatment-resistant paroxysmal atrial fibrillation (AF), a new spherical device produced the highest rate so far of sustained pulmonary vein isolation and freedom from the arrhythmia at 1 year. The results, characterized

This is because researchers haven’t had

Peer-Reviewed Publication Toho University image: An aorto-venocaval shunt (AVS) produces chronic volume overload for ≥12 weeks, leading to the formation of arrhythmogenic substrates in the rat atria, and the TRPC3 inhibitor pyrazole-3 (Pyr3) effectively suppresses sustained atrial fibrillation.

by University of California, San Francisco edited by Andrew Zinin  Editors’ notes Credit: CC0 Public Domain Drinking coffee can protect against atrial fibrillation (A-Fib), a common heart rhythm disorder that causes rapid, irregular heartbeat and can lead to stroke and heart failure. Doctors typically recommend that people with heart issues like A-Fib avoid caffeine out of fear
