The Prognostic Significance of Cardiac Structure and Function in Atrial Fibrillation: The ENGAGE AF-TIMI 48 Echocardiographic Substudy

In a contemporary population of patients with AF at increased risk for thromboembolic events, larger LV size and higher filling pressures were significantly associated with increased risk for death, but neither left atrial nor LV measures were associated with thromboembolic risk. LV size and filling pressures may help identify patients with AF at increased risk for death.
