Keywords: Cardiomyopathy, Myocardium, strain, feature tracking, fast long-axisDilated cardiomyopathy (DCM) remains to attract worldwide attention for its poor prognosis and high mortality. The interaction of biatrial and biventricular deformation capacity in DCM patients is unclear. In this study, feature tracking and fast long-axis method were used to evaluate myocardial strain. We found that biventricular and biatrial strain were significantly impaired in DCM group than control group. LV GLS was obviously impaired in event group than no event group, and it showed significantly prognostic value in predicting cardiovascular events. Comprehensive CMR analysis should be performed to improve the diagnosis ability for DCM patients.
