The prognostic value of strain parameters from cardiac magnetic resonance (CMR) cine images has been rarely studied in patients with severe dilated cardiomyopathy (DCM). In this study, we retrospectively identified 129 patients with severe DCM who underwent CMR. Strain and conventional CMR parameters were acquired from baseline CMR. The prognostic value of CMR parameters and clinical data for predicting adverse events was analyzed using Cox regression analyses. Global circumferential strain (GCS) was independently associated with adverse events after adjusting for clinical and imaging risk factors. GCS from CMR feature-tracking could be useful for risk stratification in patients with severe DCM.
