The characteristics of the infarction were assessed by delayed enhancement with gadolinium. Based on standard cine images, the global circumferential strain (GCS), global radial strain (GRS), and global longitudinal strain (GLS) of the left and right ventricles were evaluated using CMR feature tracking (CMR-FT) imaging. The volume of EFV was quantified along the short-axis slices of the left and right ventricles at the end of diastole by CMR imaging. The differences in baseline characteristics, EFV, and myocardial strain parameters between the groups were compared using Pearson or Spearman correlation analysis.
