Dose-related increase in LVEF with carvedilol in nonischemic cardiomyopathy

Change in left ventricular ejection fraction (LVEF) among patients with dilated cardiomyopathy after the administration of carvedilol. There is a dose-related increase in LVEF in those with nonischemic cardiomyopathy; no such dose relationship is seen in patients with ischemic cardiomyopathy.
