Keywords: Cardiomyopathy, Cardiomyopathy, Cardiac magnetic resonanceThis study aiming at assessing the impact of malignant ventricular arrhythmia (VA+) on left ventricular (LV) function in dilated cardiomyopathy (DCM) patients using cardiovascular magnetic resonance (CMR) feature tracking (FT). 34 VA+ and 39 VA- (benign) DCM patients were measured with CMR cine imaging. Although the left ventricular ejection fraction was similar between these two groups, FT results showed the global longitudinal peak strain (GLS) was significantly lower in VA+ than in VA-. GLS had certain diagnostic value for differentiate VA+ and VA- in DCM patients. Glycosylated hemoglobin (HBA1c) was an independent determinant parameter for GLS in DCM patients.
