A Case of Dilated Cardiomyopathy with Functional Recovery along with the Disappearmnace of Electrical Dyssynchrony on Response to Pharmacotherapy

A 70-year-old male was diagnosed and treated as non-ischemic dilated cardiomyopathy (DCM) with complete left bundle branch block (CLBBB). We observed him during 5 years after administration of anti-neurohumoral agents such as carvedilol and enalapril. There was no significant improvement in LVEF or changes in QRS formation during the first 3 years. He had stably mild heart failure (HF) complaints of NYHA class II and no re-hospitalization. However, CLBBB improved to normally narrow QRS at 3 years later and subsequent LVEF at 4 years later was improved to a normal rage of LVEF 66%.
