The PRAGUE-25 study evaluated the effectiveness of two treatment strategies in patients with both atrial fibrillation (AF) and obesity: catheter ablation versus lifestyle modification (including weight loss and increased physical activity) combined with antiarrhythmic drug therapy. While motivated patients who adhered to lifestyle changes experienced a reduction in AF episodes, the study found that catheter ablation was significantly more effective in achieving and maintaining sinus rhythm.

In this episode, Drs. Joseph Marine and Pavel Osmancik discuss the trial’s findings, highlighting that catheter ablation outperformed lifestyle modification and medication in restoring and sustaining normal heart rhythm.
