Platelet Count Applicability in Predicting the Degree of ST-Segment Depression and Coronary Flow Rate in Acute Myocardial Infarction Patients

It is still unclear whether platelet count can predict the outcomes of acute myocardial infarction. In this study, we assessed the relationship between the initial platelet count on the degree of ST-segment depression and coronary flow rate among patients with MI who underwent percutaneous coronary intervention (PCI).

In this study, a total of 218 patients suffering from MI, who underwent primary PCI during 2016-2017 (Seyed-Shohada hospital, Urmia, Iran) were selected by consensus method. Demographic information and past medical history such as diabetes mellitus (DM), cigarette smoking, using Integrilin, and door-to-balloon (DTB) time were recorded. All patients were investigated in terms of cell blood count. Serial electrocardiogram (ECG) was also performed and the degree of ST-segment elevation was measured.

The mean (SD) age of participants was 58.67 (11.44) years. The initial platelet count was similar between patients with and without improvement in the ST-segment (P=0.275). There was no significant difference regarding thrombolysis in myocardial infarction (TIMI) between patients with and without improved ST-segment (P=0.380).

According to our results, the initial platelet count in patients who underwent angioplasty was not associated with coronary flow and echocardiographic responses to treatment
