Description of intervention(s) / exposure
This study involves a randomised, double-blind, placebo-controlled trial to determine whether oral administration of carvedilol over a 6-month period will reduce left ventricular dimensions in asymptomatic individuals who have a family history of dilated cardiomyopathy and echocardiographic changes that are suspected to represent early disease.
