In 971 moderate- to high-risk subjects (CHADS2 score ≥ 2) with AF enrolled in the echocardiographic substudy of ENGAGE AF–TIMI 48, death was more frequent than thromboembolism.
Larger LV size and higher filling pressures were associated with increased risks for death.
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.
