Mean platelet volume in ST elevation and non-ST elevation myocardial infarction

Platelet activation is thought to play a key pathogenetic mechanism in acute coronary syndromes. We investigated the mean platelet volume and platelet count in patients with both ST elevation myocardial infarction and non-ST elevation myocardial infarction. Fifty two patients with non-ST elevation myocardial infarction and 56 patients with ST elevation myocardial infarction were enrolled in the study. Age- and gender-matched 50 healthy subjects constituted the control group. Venous blood samples for whole blood analysis were drawn on admission and analyzed by an autoanalyser. The difference in mean platelet volume was statistically significant in ST elevation myocardial infarction and non-ST elevation myocardial infarction patients, which was 8.7±1 and 7.9±0.7 fl (p
