Hirono K, Hata Y, Ichimata S, Nishida N, Imamura T, Asano Y, et al.
Sci Rep . 2024 Dec; 14(1):30469. PMID: 39681577
Dilated cardiomyopathy (DCM) is a progressive myocardial disorder characterized by impaired cardiac contraction and ventricular dilation. However, some patients with DCM improve when experiencing left ventricular reverse remodeling (LVRR). Currently,...
