Regional strain differentiates mild, moderate, and severe DMD CMP from healthy control subjects. A Stratification paradigm for healthy controls (n = 25) and DMD CMP (n = 43) patients between those without myocardial delayed enhancment (MDE) and an LVEF >55% (Group A, n = 15) those with MDE and LVEF > 55% (Group B, n = 15) and those with MDE and LVEF < 55% (Group C, n = 13). B–D) Basal region peak circumferential strain (Ecc; B), radial strain (Err; C), and surface area strain (Ea; D) shows differences between healthy controls and DMD CMP groups A, B, and C. Basal region systolic strain rates for Ecc (E), Err (F), and Ea (G), show significant differences between healthy controls and DMD CM groups A, B, and C. *p < 0.05, **p < 0.01,***p < 0.001 ****p < 0.001, error bars depict median and interquartile range
