Background: Inflammatory indicators such as alterations in neutrophils, platelets, and lymphocytes are linked to the acute coronary syndrome. This research seeks to understand the association of the Platelet Lymphocyte Ratio (PLR) and Neutrophil-Lymphocyte Ratio (NLR) with the Grace score as well as the association between NLR and PLR with High Sensitivity Troponin T (hs-cTnT) as a serum biomarker that aids in ACS diagnosis.
Methods: The 99 patients who met the inclusion criteria for this study were the subject of an analytical investigation with a retrospective cross-sectional design. Based on the ratio of lymphocytes to neutrophils, NLR is determined. Based on the ratio of platelets to lymphocytes, PLR is determined. hs-cTnT laboratory samples were collected more than three hours after the ischemia complaint first manifested, using the Grace risk score as a predictor of mortality. Using SPSS program 25.0, data were examined.
Results: Bivariate analysis using the Spearman correlation test. There is a correlation between NLR and GRACE risk scores (r=0.348; p<0.001), PLR and GRACE risk scores (r=0.434; p<0.001), NLR and hs-cTnT (r=0.343; p=0.001), PLR and hs-cTnT (r=0.284; p=0.004). ROC curve analysis, NLR cut-off value 4.45 (sensitivity 73.3%; specificity 72.6%), and PLR cut-off value 139.77 (sensitivity 66.7%; specificity 59.5 %) to detect High grace score. NLR cut-off value 2.17 (sensitivity 62.9%; specificity 60 %), and PLR cut-off value 108.38 (sensitivity 60.7%; specificity 60 %) to detect High hs-cTnT.
Conclusion: In this study, there was a relationship between NLR and PLR with the Grace risk score as well as a relationship between NLR and PLR with hs-cTnT.
