Evaluation of infarct size and microvascular reperfusion on angiography and cardiac magnetic resonance in patients with ST-segment elevation myocardial infarction

چکیده
Background Impaired microvascular reperfusion (no-reflow) and unsuccessful infarct-related artery (IRA) revascularization are associated with worse clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI). Successful reperfusion can be estimated by epciardial and microvascular flow. Both of them can be evaluated by angiography as Thrombolysis in Myocardial Infarction (TIMI) flow grade and myocardial blush grade (MBG). Moreover microvascular obstruction (MVO) determined by CMR is also a well known predictor of unfavorable clinical outcome after STEMI. The aim of the study was to evaluate the effect of impaired reperfusion estimated by angiography on microvascular obstruction and infarct size (IS) measured by CMR in STEMI.
