Safety and efficacy of catheter ablation in atrial fibrillation patients with heart failure with preserved ejection fraction.

ABSTRACT:

Purpose

Catheter ablation (CA) for atrial fibrillation (AF) in heart failure patients with preserved ejection fraction (HFPEF) has shown promising results in reducing mortality and improving heart function. However, previous studies have been limited by a lack of control groups and significant heterogeneity in their methodologies.

Hypothesis

CA for AF in HFPEF patients may not increase the complications and had similarly the rate of freedom from AF vs. patients without HFPEF, and it may reduce hospitalizations and mortality and improve heart function VS medical treatment.

Methods

Three groups of AF patients were included in the study: 187 patients with HFPEF for their first CA (AFPHF-CA), 187 patients with HFPEF who were undergoing medical therapy (AFPHF-Med), and 196
