Relapse in patients with non-ischemic dilated cardiomyopathy and improved ejection fraction managed with medical therapy

BACKGROUND: Relapse is an important problem in nonischemic dilated cardiomyopathy (DCM) patients with improved left ventricular ejection fraction (LVEF). This study aimed to determine the long-term outcomes of patients with non-ischemic dilated cardiomyopathy and improved ejection fraction and analyse the risk of relapse in patients being managed with medical therapy. METHODS: This was a single-centre, retrospective, observational study of all adult patients with non-ischemic DCM enrolled in a cohort. Patients with improved LVEF defined as LVEF
