About

To evaluate the efficacy of catheter ablation and rate control in heart failure patients with atrial fibrillation.

Full description

All patients received either catheter ablation for rhythm control or rate control before enrollment, and the investigators do not assign specific interventions to the subjects during the study. So this study might be considered to be observational.

Enrollment: 394 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• age>18 years
• documented atrial fibrillation
• New York Heart Association Ⅱ-Ⅳ or left ventricular ejection fraction <50%

Exclusion criteria

• heart failure that had a suspected reversible cause
• previous ablation
• any contraindication to catheter ablation

Trial design

394 participants in 2 patient groups

catheter ablation group

Description:

atrial fibrillation patients with heart failure who received catheter ablation for rhythm control

rate control group

Description:

atrial fibrillation patients with heart failure who received pharmacological approaches for rate control
