Myocardial Gene Expression in Dilated Cardiomyopathy Treated with Beta-Blocking Agents

Abstract
Beta-blocker therapy may improve cardiac function in patients with idiopathic dilated cardiomyopathy. We tested the hypothesis that beta-blocker therapy produces favorable functional effects in dilated cardiomyopathy by altering the expression of myocardial genes that regulate contractility and pathologic hypertrophy.
