Extract

Introduction: A strong association between obstructive sleep apnea (OSA) and atrial fibrillation/atrial flutter (AF) has been consistently observed in both epidemiological and clinical cohort studies. The effect of treatment with positive airway pressure (PAP) on AF recurrence is not conclusive. This study aims to evaluate the effect of treatment of sleep apnea with PAP on AF recurrence.

Methods: This is a single-center retrospective study conducted at a tertiary referral hospital. All adult patients who had OSA documented by polysomnography (PSG) and had AF intervention (ablation or cardioversion) after PSG from January 1992 to December 2014 were analyzed in this study. The primary outcome was time to recurrence of AF after AF intervention calculated by Kaplan-Meier.
