Abstract: Background : Sleep disordered breathing (SDB) is a well known risk factor associated with atri al fibrillation (AF).The purpose of this study was to investigate the relationship between SDB and the clinical outcome of catheter ablation in patients with AF.Methods : A total of 191 consecutive AF patients underwent catheter ablation were included.Prior to the procedure, overnight peripheral oxygen saturation was recorded by pulse oximetry diag nose the presence/absence of SDB.Early recurrence of AF (ERAF) and late recurrence of AF (LRAF) were defined as AF which occurred within three days following the procedure, and AF after a 90 day blanking period, respectively.Results : SDB was diagnosed in 16.8% (32/191) of all patients.ERAF and LRAF were observed in 37.1% (71/191) and 20.9% (40/191) of patients, respectively.SDB was more frequently observed in patients with ERAF than in those without it (29.6%(21/71) vs. 9.2% (11/120), P<0.001), while SDB was observed at similar levels in patients with and without LRAF (20.0%(8/40) vs. 15.9%(24/151), P=0.70).Conclusion : Although SDB was significantly associated with the occurrence of ERAF, it had no impact on LRAF following the catheter ablation of AF, which may be due to the different mechanisms of AF recurrence between the early and late clinical phases.(
