Synopsis

To evaluate the value of left ventricular radial strain (LVRS) and left ventricular circumferential strain (LVCS) in discriminating between hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD) by using cardiac magnetic resonance feature tracking (CMR-FT). HCM patients presented higher values of LVRS and LVCS when compared with HHD patients. And both LVRS and LVCS correlated obviously with left ventricular ejection fraction (LVEF) in HCM patients. Furthermore, the combination of strain with LGE can significantly improve the diagnostic ability for differentiation HCM from HHD (AUC: 0.86; sensitivity: 86.9 %; specificity: 76.3 %).
