The Preventive Efficacy of Carvedilol on Cardiac Dysfunction in Duchenne Muscular Dystrophy

Purpose This cardiac dysfunction in patients with Duchenne muscular dystrophy is associated with minor cardiac damage as indicated by elevation of plasma cardiac troponin I (cTnI). The purpose of this study is to investigate whether the administration of Carvedilol can suppress the minor cardiac damage and prevent deterioration of cardiac function.
