effect of B blocker was first evaluated in patient with cardiomyopathy not induced by ischemia and idiopathic which as the most common causes of cardiomyopathy. Effect of BB on Thalassemia cardiomyopathy was evaluated in this study

Clinical Details

Official title: The Effect of Metoprolol Succinate on the Cardiac Function of Patients With Thalassemia Cardiomyopathy a Double Blind Randomized Study

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome:
