Objective In a significant proportion of patients with ST-elevation myocardial infarction (STEMI), microvascular and myocardial reperfusion cannot be regained despite successfully restored thrombolysis in myocardial infarction (TIMI) grade 3 epicardial blood flow. Myocardial blush grade (MBG) is a reliable marker for microvascular patency and predicts short-term and long-term mortality after primary percutaneous coronary intervention (PCI) in patients with acute STEMI, independent of other variables. Mean platelet volume (MPV), a unique measure of platelet size, is an indicator of platelet reactivity. In this study, we aimed to investigate the relation of admission MPV with postinterventional MBG in patients with STEMI and TIMI grade 3 flow at infarct artery after primary PCI.
