Impella effects on reverse myocardial remodeling in anterior ST-elevation myocardial infarction: insights from a comprehensive analysis of acute and chronic MRI findings.

Background: Late adverse myocardial remodeling after ST elevation myocardial infarction (STEMI) is strongly associated with cardiac death. Global Longitudinal strain (GLS) and circumferential diastolic strain rate (CDSR) derived cardiovascular magnetic resonance imaging (CMRI) is a powerful predictor of late myocardial remodeling. However, the Impella's effects on CMRI after STEMI are not fully understood.
