摘要

Catheter ablation of atrial fibrillation (AF) is known to facilitate reverse remodeling of the left ventricle. However, factors that can improve the left ventricular (LV) systolic function remain elusive. In this study, we investigated factors related to LV ejection fraction (LVEF) improvement following AF ablation in patients with systolic dysfunction. A total of 140 patients with impaired LVEF ( = 5.4 independently predicted the outcome after adjusting for confounders (hazard ratio 1.74; 95% confidence interval 1.06 to 2.95; p = 0.03; hazard ratio, 1.99; 95% confidence interval 1.13 to 3.64; p = 0.01). LVEF improvement was achieved in 69% of patients who underwent AF ablation, including 4% with late improvement. Lower LVESVI and higher e' could independently predict LVEF improvement.
