Objective: ST-segment elevation myocardial infarction (STEMI) is an important cause of morbidity and
mortality. Platelet (PLT) activation and thrombosis have important roles in the process of atherosclerosis
that is one of the most important cause of acute ischaemic syndromes. PLT count is related with
inflammation and mean platelet volüme (MPV) is an important marker of PLT activation. Both
parameters are found to be related with increased cardiovascular risk. In this study we aimed to
investigate clinically usability of a new parameter:MPV/PLT ratio, in the diagnosis of patients with
Troponin I elevated STEMI.
Material and Methods: 92 male patients with STEMI-underwent percutaneous coronary intervention
(PCI) successfully and 75 healthy subjects were enrolled in the study. T-test was used to determine
significant differences between the groups for data with normal distribution and Spearman’s analysis
was used to deterMIne the correlations between the variables. Independent predictive factors were
found for PLT, MPV and MPV/PLT ratio of patients with STEMI.Characteristic ROC curves were performed,
optimal cut-off points were determined.
Results: Significant differences were determined for PLT, MPV and MPV/PLT ratio levels of patients
(P<0.001). Optimal cut off points were 262.5 for PLT(AUC 0.488;sensitivity 50%, specifity 52%);10.45
for MPV(AUC 0.700, sensitivity 69%, specifity 54%) and 0.043 for MPV/PLT(AUC 0.788, sensitivity 71%,
specifity 64%).
Conclusion: MPV/PLT ratio was demonstrated to be associated with patients with STEMI with a higher
spesifity and sensitivity than PLT and MPV. Also, higher MPV/PLT ratio was associated with greater
SYNTAX score.We suggest that an elevated level of MPV/PLT ratio may be of benefit to predict severity of
these patients.
