Abstract
The influence of depression on the recurrence of atrial fibrillation (AF) after catheter ablation remains unclear. We performed a meta-analysis to evaluate the association between depression and AF recurrence after catheter ablation. Cohort studies that evaluated depression at baseline and correlated depression with AF recurrence after catheter ablation were identified by searching the PubMed and Embase databases. Heterogeneity was determined using the Cochrane's Q test and calculating the I Our analysis included seven cohort studies with 1,070 AF patients who underwent catheter ablation by circumferential pulmonary vein isolation. No significant heterogeneity was detected among the included studies (p for Cochrane's Q test = 0.20, I This analysis included a limited number of studies and various instruments applied to measure depression. Depression is an independent risk factor of AF recurrence after catheter ablation.
