A randomized trial published in JAMA examined whether weight loss reduces recurrence of atrial fibrillation. The study found that weight loss was unlikely to prevent recurrence in patients with chronic, persistent atrial fibrillation. For patients whose atrial fibrillation was new and lasted less than one year, weight loss showed a higher likelihood of preventing recurrence, consistent with an earlier randomized trial.

The findings distinguish outcomes by duration of the condition.
