Materials and Methods: The patients were divided into three groups according to their SYNTAX score. Group 1 included patients with a SYNTAX score <23, group 2 with a SYNTAX score of 23-32, and group 3 with a SYNTAX score of >33. PLR was calculated as the ratio of platelet count to lymphocyte count. Results: In multivariate logistic regression analysis, high PLR and NLR ratios and older age were independent predictors of high SYNTAX score II [odds ratio (OR): 1.052; 95% confidence interval (CI): (0.998-1.119), p=0.011; OR: 1.093; 95% CI: (1.016-1.175), p=0.016; OR:1.023; 95% CI: (1.0101.038), p=0.001, respectively. Patients with high PLR had significantly higher SYNTAX scores [121.7 (114.2-129.3) in group 1; 139.4 (125.9-153.0) in group 2, 187.0 (141.8-232.2) in group 3; p<0.001], and there was a positive correlation between PLR, NLR and SYNTAX scores (r=0.52, p<0.001; r=0.58, p<0.001, respectively). Conclusion: PLR and NLR were associated with the severity and complexity of coronary artery disease in patients with acute ST-elevation myocardial infarction.eninfo:eu-repo/semantics/openAccessLymphocytes; neutrophils; coronary artery disease; inflammationArticle12317117510.4274/nkmj.galenos.2024.972681282778WOS:001325743200004N/A
