Zhang C, Zhao L, Zhu E, et al. - In this study, the predictors of moderate to severe ischemic mitral regurgitation (IMR) after myocardial infarction with cardiovascular magnetic resonance (CMR) were examined. Researchers retrospectively examined a total of 109 patients (mean age 60 ± 8 years) with IMR between January 2016 and September 2018. They further evaluated the presence of papillary muscle infarction (PMI), global left ventricular (LV) infarcted extent, LV functional parameters, and LV myocardial strain. Factors in the development of moderate to severe IMR were distinguished by conducting univariate and multivariate analyses. It was shown that in patients with moderate-to-severe IMR, the incidence of PMI was higher. The findings suggested that the extent of global LV infarcted extent and global longitudinal strain were independent predictors of moderate-to-severe IMR.
