Predictive Value of NLR,PLR and sPESI Score for 30-day Mortality in Patients with Acute Pulmonary Embolism
Objective To investigate the predictive value of neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),and the simplified pulmonary embolism index(sPESI)score for 30-day death in patients with acute pulmonary embolism(APE).Methods The clinical data of 291 APE patients admitted to Xuanwu Hospital of Capital Medical University from January 2017 to December 2021 were retrospectively analyzed.White blood cell count(WBC),NLR,PLR,sPESI score,and other indicators were calculated at admission.The patients were followed up within 30 days and were divided into the death group and the survival group accord-ing to the prognosis.The differences in the above indexes between the two groups were compared.Multivariate Logistic regression was used to analyze the independent risk factors for 30-day mortality in APE patients.The area under the receiver operating characteristic(ROC)curve of NLR,PLR,and combined sPESI scores in predicting mortality was compared.Results Among the APE patients,11 cases(3.78％)died and 280 cases(96.22％)survived within 30 days.The WBC,NLR,PLR,and sPESI score in the death group were sig-nificantly higher than those in the survival group(P＜0.05).Multivariate Logistic regression analysis showed that PLR,NLR,and sPESI score were independent risk factors for 30-day mortality in APE patients(P＜0.05).The area under ROC curve(AUC)of PLR in pre-dicting the 30-day death of APE patients was 0.799(P=0.001).The AUC of NLR was 0.827(P=0.001).The AUC of sPESI score was 0.874(P=0.001).There was no significant difference in the AUC of PLR,NLR,and sPESI score in predicting death(P=0.181,0.340);the AUC of NLR combined with sPESI score was 0.925(P=0.001),which was greater than that of NLR(P=0.004).The AUC of PLR combined with sPESI score was 0.901(P=0.001),which was greater than that of PLR(P=0.002).Conclusion NLR,PLR,and sPESI score are independent risk factors for 30-day mortality in APE patients,and all of them have certain prognostic values.The prognostic value of PLR and NLR combined with sPESI score was higher than that of PLR and NLR alone.
