Comparison of Mean Platelet Volume in Acute Myocardial Infarction vs. Normal Coronary Angiography.

Considering the importance of cardiovascular disease and the role that platelets have in thrombosis formation in the coronary arteries, this study was done in order to assess platelet-related indices in patients who suffered acute myocardial infarction (MI) and compare them with those who had normal coronary angiography results.In this descriptive-analytical study, 200 patients who were admitted to our university hospital due to chest pain were included. The patients were divided into five groups including ST-segment elevation MI (STEMI), non-STEMI, unstable angina (UA), stable angina (SA), and healthy subjects (as control group). Platelet-related indices including platelet count as well asmean platelet volume (MPV) was determined. For this purpose, blood samples were taken from the patients upon admission and platelet count and volume were measured within three hours of admission.There was no statistically significant difference regarding MPV between the study groups (P> 0.05).MPV did not have any role in diagnosing various types of coronary artery disease (CAD).
