Obstructive Sleep Apnea Is Closely Related to Cardiovascular Risk Factors, but Not to Clinical Recurrence of Atrial Fibrillation after Catheter Ablation: An Analysis of Atrial Fibrillation Patients.

ABSTRACT:

Background

Obstructive sleep apnea (OSA) is a well-known predictor of atrial fibrillation (AF). However, OSA usually accompanies other risk factors of AF. We tried to investigate whether OSA is related to AF recurrence after catheter ablation.

Methods

A total of 378 patients (mean age 59.9 ± 10.7 years, 72.5$ male) who underwent catheter ablation of AF were enrolled and underwent overnight ambulatory polysomnography before the ablation procedure. These patients were examined once every 3 months at the outpatient clinic to determine AF recurrence.

Results

Based on the apnea-hypopnea index (AHI), we divided the study subjects into 3 groups defined as mild (AHI < 10), moderate (10 30) OSA. Patients with severe OSA had a higher prevalence of h
