The Association Between Hematologic Indices With TIMI Flow In STEMI Patients Who Undergo primary percutaneous coronary intervention.

Abstract

The Primary Percutaneous Coronary Intervention (PPCI) is the preferred therapeutic strategy for patients who experienced ST-Elevation Myocardial Infarction (STEMI). We aimed to evaluate the association of hematological indices, including hemoglobin level, platelets, White Blood Cells (WBCs) count, and MPV before PPCI with the TIMI grade flow after PPCI. STEMI patients who experienced PPCI were included in the present retrospective crosssectional study. Then participants were divided into three groups based on their post-procedural TIMI flow grades. Demographic data and hematologic indices of patients before PPCI were collected and their association with the TIMI grade flow after PPCI was evaluated. To compare the quantitative and qualitative variables, chi-square and t-tests were performed, respectively. We found that elevated levels of hemoglobin and decreased levels of MPV had a significant association with an advanced grade of TIMI flow. Interestingly, in the normal range, there was a significant association between higher platelet count and TIMI-flow grade 1. Besides, TIMI flow grades 2 and 3 had a significant association with low and moderate platelets count, respectively. In conclusion, evaluating MPV, platelets, and hemoglobin levels before PPCI as easy and accessible parameters may be able to identify high-risk STEMI patients undergoing PPCI.
