AF patients who cut back on the booze enjoy better symptom control and more time between fibrillation episodes, a landmark Australian study suggests.

Abstinence led to a 37% increase in days free of any atrial tachyarrhythmia lasting 30 seconds or more (118 vs 86 days) in patients with paroxysmal AF, according to the study led by the Alfred Hospital and Baker Heart and Diabetes Institute in Melbourne.
