This study aims to identify the risk factors for adverse events in dilated cardiomyopathy (DCM) patients with LVEF≥35% and establish a scoring model to predict adverse event risk. 269 consecutive DCM patients with LVEF ≥35% who underwent gadolinium-enhanced cardiac magnetic resonance (CMR) imaging were enrolled in this study. The primary endpoint was a composite of SCD or aborted SCD. Secondary endpoints were all-cause mortality, heart transplantation and hospitalization for heart failure. The nomogram we created using these parameters provides a novel way to clinically assess and risk stratify this patient population.
