Accurate risk stratification of nonischemic dilated cardiomyopathy (NIDCM) remains challenging. ⋯ The presence and extent of LGE were associated with various adverse clinical outcomes, whereas LVEF was not significantly associated with mortality and arrhythmic end points in NIDCM. Risk stratification using native T1 relaxation times, extracellular volume fraction, and global longitudinal strain requires further evaluation.
