Abstract:
Objective To investigate the predictive value of neutrophil-to-lymphocyte ratio(NLR)and other factors for hemorrhagic transformation(HT)after intravenous thrombolysis in acute ischemic stroke(AIS).Methods A retrospective study was conducted on 260 AIS patients who received intravenous thrombolysis with alteplase in Department of Neurology of Hexian People's Hospital from August 2020 to June 2024.According to HT occurred or not after thrombolysis,they were divided into HT group(n=42)and non-HT group(n=218).The clinical baseline data were compared between the two groups.Multivariate logistic regression analysis was used to iden-tify the risk factors of HT,and ROC curve was drawn to analyze the predictive value of NLR and other risk factors for HT in AIS patients after intravenous thrombolysis.Results Among the 260 AIS patients,42 cases(16.2％)had HT.The proportion of atrial fibrillation and cardioembolism type(TOAST subtype CE),white blood cell count,neutrophils count,NLR,and baseline NHISS score were significantly higher,and the lymphocyte count was obviously lower in the HT group than the non-HT group(all P＜0.05).Multivariate logistic regression analysis showed that atrial fibrillation(OR=3.361,95％CI:1.015-15.381),NHISS score ≥15(OR=7.785,95％CI:1.348-21.312),TOAST classification CE(OR=4.104,95％CI:1.156-17.256),and NLR(OR=3.165,95％CI:1.231-5.265)were independent risk factors for HT(all P＜0.05).ROC curve analysis showed that the AUC value of NLR combined with above other factors was 0.841(95％CI:0.763-0.967,P＜0.01).In Hosmer-Lemeshow goodness of fit test on the model(P=0.354),the best critical value was 0.701,the sensitivity was 86.3％,and the specificity was 84.3％.Conclu-sion NLR combined with TOAST etiological classification and other factors have a certain pre-dictive value for the occurrence of HT after intravenous thrombolysis.
