Effective risk assessment and stratification are essential for the clinical management of ST-segment elevation myocardial infarction (STEMI) patients. CMR imaging has become a beneficial imaging modality to assess myocardial morphology, function and infarct characteristics simultaneously. This study quantitatively evaluated relationship between microvascular obstruction and regional myocardial strain by Cardiac MRI after ST-segment-elevation myocardial infarction. Our data showed that regional strain parameters may be s new noninvasive imaging markers allowing comprehensive evaluation regional myocardium deformation.
