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 the relationship between infarct size, regional myocardial function by cardiac magnetic resonance feature tracking strain analysis and infarct location in patients with STEMI treated by primary percutaneous coronary intervention. Our data showed that myocardial damage was more extensive and regional myocardial function in infarct zone was lower in the anterior wall myocardial infarction group compared to non-anterior wall myocardial infarction group.
