Abstract

BACKGROUND: Platelets play an important role in developing intravascular thrombus, the major cause of acute coronary syndromes. We investigated the clinical value of mean platelet volume (MPV) in coronary atherosclerosis and its possibility of being an independent risk factor for acute myocardial infarction (MI). MATERIAL/METHODS: Two hundred patients who underwent coronary angiography were included in the study. Thirty-five patients were randomly selected for each of the four study groups of stable (SAP) and unstable (USAP) angina pectoris and MI with and without ST-segment elevation. Sixty patients with chest pain having normal coronary angiograms were controls. The groups were compared regarding age, sex, smoking, diabetes, hypertension, positive family history, number of diseased vessels, lipid profile, complete blood count, creatine kinase (CK)-MB, Troponin-I, and MPV. RESULTS: MPV was found to be elevated in MI patients compared with controls (p
