Purpose: This study aims to evaluate the relationship between the platelet/lymphocyte ratio (PLR) measured at admission and the occurrence of no-reflow phenomenon in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). Materials and Methods: This study included 126 patients with acute STEMI treated with primary PCI. Hemoglobin, thrombocyte, and lymphocyte levels of the patients were retrieved from the files at the time of admission. Postprocedural thrombolysis in myocardial infarction (TIMI) flow grade, postprocedural myocardial blush grade (MBG), and TIMI thrombus scale were evaluated from the coronary angiography records. Results: Patients were divided into two groups according to TIMI flow grade after PCI as normal coronary flow (n = 66) and no-reflow groups (n = 60). The no-reflow group had lower LVEF and higher PLR compared to the normal coronary flow group PLR was significantly higher in patients with lower TIMI flow grade and MBG. Conclusion: PLR measured at admission was found to be higher in STEMI patients who developed no-reflow after primary PCI compared to the normal coronary flow group. PLR can be used as a predictor for no-reflow in such patients.
