Efficacy of continuous positive airway pressure on atrial fibrillation recurrence after catheter ablation in patients with obstructive sleep apnea: a systematic review and meta-analysis.

Background: Obstructive sleep apnea (OSA) is associated with an increased risk of atrial fibrillation (AF). However, the impact of continuous positive airway pressure (CPAP) on the recurrence of AF after catheter ablation (CA) in patients with OSA remains unclear.

Methods: We systematically searched PubMed, Embase, and Cochrane databases for randomized controlled trials (RCTs) and observational studies comparing CPAP vs.
