Abstract：ObjectiveTo study the applicability of the platelet to lymphocyte ratio (PLR) in evaluating the new onset atrial fibrillation among elderly male patients with acute myocardial infarction (AMI)during hospitalization.Methods A total of 241 elderly male patients with AMI who were treated in the Department of Cardiology of a hospital between January 2014 and December 2018 were included in this study. These patients were divided into the atrial fibrillation group and the non-atrial fibrillation group based on the occurrence of NOAF during admission. The medical records of the two groups of patients were collected. Logistic regression analysis and the receiver operating characteristic (ROC)curve were used to analyze the potential of PLR to predict the occurrence of NOAF in elderly male AMI patients.Results (1) Logistic regression analysis showed that serum triglyceride (TG), left ventricular ejection fraction (LVEF), and PLR were independent risk factors for NOAF in elderly male AMI patients after admission(P<0.05). (2)ROC curve analysis showed that the best cutoff point for PLR to predict NOAF in elderly male patients of AMI after admission was 248.11. The sensitivity of prediction was 87.90%, the specificity was 95.9%, and the area under the AUC curve was 0.969(95%CI: 0.939~0.9998;P<0.001).Conclusions PLR is significantly related to the occurrence of NOAF in elderly male AMI patients.
