Meta-Analysis of Catheter Ablation versus Medical Therapy in Patients with Atrial Fibrillation Without Heart Failure.

ABSTRACT:

Introduction

Catheter ablation has shown to reduce mortality in patient with atrial fibrillation (AF) and heart failure (HF) with reduced ejection fraction. Its effect on mortality in patients without HF has not been well elucidated.

Methods

Thirteen randomized controlled trials encompassing 3856 patients were selected using PubMed, Embase and the CENTRAL till April 2019. Estimates were reported as random effects risk ratio (RR) with 95% confidence intervals (CI).

Results

Compared with medical therapy, catheter ablation did not reduce the risk of all-cause mortality (RR, 0.86, 95% CI, 0.62-1.19, P=0.36; I2=0), stroke (RR, 0.55, 95% CI, 0.18-1.66, P=0.29; I2=0), need for cardioversion (RR, 0.84, 95% CI, 0.66-1.08, P=0.17; I2=0) or pacemaker (RR, 0.59, 95% CI, 0.34-1.01
