Current study reported that early detection and early rhythm control therapy in patient with Atrial Fibrillation (AF) was associated with a lower risk of cardiovascular outcomes than usual care for AF. Early detection and early treatment for AF is important. However, subclinical AF is likely to go undetected and untreated, because patients with subclinical AF had no symptoms. It is unclear the relationship subclinical AF and Heart Failure (HF). This review summarizes the relationship between subclinical AF and HF hospitalization in patients with cardiac dysfunction using Cardiac Resynchronization Therapy Defibrillator (CRT-D).
