Objectives. To study myocardial perfusion in ST-elevation myocardial infarction (STEMI) treated successfully with primary angioplasty. Additionally, to evaluate the predictive value of perfusion on subsequent infarct size. Design . Fifty patients with acute STEMI and restoration of normal epicardial flow after primary angioplasty were included in the study. TIMI myocardial perfusion (TMP) grades were determined at the end of the procedure. Contrast enhanced magnetic resonance imaging (MRI) including first-pass perfusion and delayed enhancement imaging were performed within five days and after three months. Results . The patients were divided into two groups: A?=?TMP 0–1, B?=?TMP 2-3. The early MRI showed significantly reduced myocardial perfusion in the infarct zone compared to remote myocardium in both groups (p? [ABSTRACT FROM AUTHOR]
