study of platelet parameters in the patients with acute myocardial infarction referred to Ali Shariati Hospital in 2018

Abstract

Introdution: The rapid and accurate diagnosis of acute myocardial infarction is essential for effective treatment. Recently, troponin has been introduced as a biochemical marker for early diagnosis of acute myocardial infarction. Platelet parameters (P-LCR, MPV, PDW) play a key role in the pathophysiology of acute coronary syndrome. The aim of this study was to evaluate platelet indexes in the patients with acute myocardial infarction.

Methods: In this cross- sectional descriptivestudy, 345 patients with acute myocardial infarction who referred to Shariati Hospital with chest pain were examined in 2018. Troponin was measured by Enzyme-Linked Fluorescence Assay. The platelet indexes of the patients were determined by Hydrodynamically focused detection method.

Results: The results of Spearman correlation test between the three variables MPV, PLCR and PDW showed that there was a significant relationship between platelet parameters. Spearman correlation coefficient between two variables PLCR and troponin also showed a significant positive correlation.

Following an increase in the proportion of large platelets, the serum levels of troponin were increased in the affected patients. Mean of the MPV, PLCR and PDW were obtained (10.37, 27.74, 12.15femtoliter), respectively.

Conclusion:Platelet indexes of the MPV, PLCR and PDW can be considered as potent and non-dependent prognostic factors in the patients with acute myocardial infarction. In this study, P-LCR was more pronounced than other platelet indexes.
