Changes in left ventricular ejection fraction (LVEF) at 1 y. Improvement in LVEF by at least 5% was present in a significantly higher proportion in nonischemic dilated cardiomyopathy patients with baseline left ventricular end-diastolic volume (LVEDV) between 200 and 370 mL (group B) when compared to patients with baseline LVEDV less than 200 mL (group A).
