Abstract

The role of catheter ablation in patients with atrial fibrillation (AF) in enhancing long-term outcomes remains unknown. This meta-analysis aimed to assess the impact of catheter ablation on stroke, all-cause mortality, hospitalization due to heart failure, and major bleeding events in patients with atrial fibrillation. This meta-analysis was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The data search was carried out by two authors independently using online databases including PubMed, EMBASE, and Cochrane library. The primary outcome was a stroke. The secondary outcomes were all-cause mortality, hospitalization for heart failure, and major bleeding events. Total, 10 articles were included in the current meta-analysis encompassing 275392 patients (33291 in the ablation group and 244974 in the non-ablation group). Among all included studies, one study was a randomized control trial, while the remaining other were retrospective cohorts. The current meta-analysis showed that catheter-based AF ablation reduced the risk of stroke (hazard ratio {HR}: 0.61, 95% CI: 0.49-0.77), all-cause mortality (HR: 0.60, 95% CI: 0.51-0.71), and hospitalization for heart failure (HR: 0.57, 95% CI: 0.43-0.76). No significant differences were reported in terms of major bleeding events between patients who received catheter-based AF ablation and patients who did not receive catheter-based AF ablation (HR: 0.96, 95% CI: 0.80-1.14). In the current meta-analysis, catheter-based AF ablation was associated with decreased risk of all-cause mortality, stroke, and hospitalization due to heart failure. However, no significant difference was reported in terms of major bleeding events.
