Intravenous Allopurinol to Improve Heart Function in Individuals With Dilated Cardiomyopathy

Withdrawn before enrolling · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Cardiovascular Diseases, Cardiomyopathy, Dilated, Heart Diseases, Heart Failure, Congestive

In brief

This study will determine whether an acute infusion of intravenous allopurinol improves the inotropic response to dobutamine in patients with idiopathic dilated cardiomyopathy (DCM) as measured by cardiac magnetic resonance imaging (CMR).
