Atrial fibrillation burden and subsequent heart failure events in patients with cardiac resynchronization therapy devices

Background Atrial fibrillation (AF) and heart failure (HF) often coexist but little is known on how AF burden associates with subsequent episodes of HF. Objective The aim of this study was to quantitatively assess the short‐ and long‐term association of AF burden with subsequent episodes of HF events in patients with reduced ejection fraction. Methods Patients with cardiac resynchronization therapy (CRT) devices with at least 90 days of device...
