In the randomized DECAF trial, patients undergoing cardioversion who consumed at least one caffeinated coffee daily experienced fewer clinically detected atrial fibrillation recurrences than those abstaining from caffeine. The study was modest in size and further validation is needed.

A randomized crossover trial of 108 habitual cannabis users found fewer premature atrial contractions on cannabis-use days than abstinence days. The short-term physiologic findings provide mechanistic insight but were not designed to evaluate long-term cardiovascular health outcomes.

Researchers identified distinct neuronal populations within the heart’s intrinsic nervous system that regulate cardiac rhythm and stress responses in mice. The findings provide mechanistic insight into cardiac neurobiology, though human relevance remains uncertain.

First-line pulsed field catheter ablation outperformed antiarrhythmic drug therapy for rhythm control at one year in patients with persistent atrial fibrillation, with similar serious adverse event rates.

ACC, AHA, and HRS jointly updated the 2015 advanced training statement for clinical cardiac electrophysiology, adding new required competencies and revised procedural benchmarks for fellowship training.

There needs to be increased awareness among primary care doctors and general cardiologists that patients with persistent symptomatic AF are sometimes better served by promptly scheduling a cardioversion while waiting for an appointment with an electrophysiologist.
