An American Heart Association scientific statement reviews the cardiovascular effects of caffeine, including randomized evidence showing a 39% lower risk of recurrent AF among habitual coffee drinkers who continued coffee after cardioversion. The discussion separates ordinary coffee consumption from energy drinks and concentrated caffeine while considering premature ventricular contractions, blood pressure, sleep, and individualized patient counseling.\nThe episode also investigates whether wine adds cardiovascular benefit to the Mediterranean diet. The apparent benefit weakened when moderate drinkers were compared with very-light drinkers, demonstrating how the reference group can change the statistical narrative. Importantly, these studies did not evaluate AF outcomes and do not support prescribing wine as cardiovascular therapy.\nOther studies covered include:\n• Pulsed-field ablation for persistent AF, with pooled one-year freedom from atrial arrhythmia of 72.3%, but no proven superiority over thermal ablation.\n• Broad and predominantly left-sided pulmonary vein reconnection patterns during redo procedures after pentaspline pulsed-field ablation.\n• Real-world Sphere-9 safety reports involving ventricular arrhythmias, implanted-device interactions, stroke, AV block, and other signals, interpreted in the absence of a procedural denominator.\n• The SMARTBEATS randomized trial of smartphone rhythm monitoring before cardioversion, which prevented approximately one same-day cancellation for every six patients monitored.\n• Autopsy-based sudden cardiac death research showing that myocardial infarction accounted for 41% of confirmed sudden cardiac deaths and highlighting the limitations of ejection fraction alone.\n• End-tidal carbon dioxide...","thumbnail_url":"https://img.transistorcdn.com/C7iPWVsHlGRm13syn3X4eXGLcqOXyzcuH5XmVutqgHc/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9jMzFi/ZTYxOTI1M2U4NGRj/OGZmZjBhMDFlMjFm/NDQwMC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
