Impact of early catheter ablation of atrial fibrillation in patients with heart failure with preserved ejection fraction-real-world evidence.
INTRODUCTION Catheter ablation for atrial fibrillation (AF) has been shown to reduce mortality and heart failure (HF) progression in patients with AF and HF with reduced ejection fraction; however, outcomes in HF with preserved ejection fraction (HFpEF), especially the optimal timing of ablation, remain uncertain.
