The Relationship between Obstructive Sleep Apnea and Atrial Fibrillation: A Complex Interplay

Table 4

Risk of AF recurrence after catheter ablation.

Investigator	Number of patients	Ablation strategy	Diagnosis of OSA	Results: recurrence of AF in patients with OSA versus no OSA [86]
Patel et al. (2010) [78]	3000	PVI plus left atrial linear ablation	PSG	RR 1.23 [1.06,1.43]
Matiello et al. (2010) [87]	174	PVI plus left atrial linear ablation	PSG	RR 1.53 [1.21,1.92]
Chilukuri et al. (2010) [88]	109	PVI	BQ	RR 0.97 [0.75,1.26]
Tang et al. (2009) [89]	178	PVI	BQ	RR 1.03 [0.61,1.73]
Chilukuri et al. (2009) [90]	210	PVI	BQ	RR 1.18 [0.93,1.49]
Jongnarangsin et al. (2008) [91]	324	PVI plus CAFE ablation	PSG	RR 1.61 [1.16,2.22]

PVI: pulmonary vein isolation; PSG: polysomnogram; RR: risk ratio; BQ: Berlin Questionnaire; CAFE: complex fractionated atrial electrograms.
