Effects of Enhanced External Counterpulsation Combined With Cardiac Rehabilitation in Patients With Atrial Fibrillation

This is a prospective randomized controlled trial designed to evaluate the effectiveness of enhanced external counterpulsation (EECP) combined with cardiac rehabilitation in patients with atrial fibrillation. The study aims to assess whether this combined intervention can improve cardiac function and exercise capacity compared to standard care alone. Eligible participants will be randomly assigned to receive either the EECP plus cardiac rehabilitation program or routine treatment. Primary outcomes include changes in left ventricular ejection fraction (LVEF) and six-minute walking distance (6MWD). The study will be conducted at Lanzhou University Second Hospital.
