Abstract:
Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) on admission for early neurological deterioration (END) in patients with lacunar stroke.Methods Patients with acute lacunar stroke admitted to the Department of Neurology,the Second People's Hospital of Lianyungang from June 2015 to October 2017 were enrolled retrospectively.END was defined as an increase of ≥2 in the National Institutes of Health Stroke Scale (NIHSS) score within 72 h of admission.Multivariate logistic regression analysis was used to determine the independent risk factors for END.The receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for END in patients with lacunar stroke.Results A total of 309 patients with acute lacunar infarction were enrolled,including 180 males (58.2％),aged 59.7 ±7.3 years;65 patients (21.0％) in END group and 244 (79.0％) in non-END group.Multivariate logistic regression analysis showed that after adjusting for other confounders,NLR was an independent risk factor for END in lacunar stroke (odds ratio 4.508,95％ confidence interval 3.128-7.547;P＜0.001).ROC curve analysis showed that the area under the curve of NLR predicting END in patients with lacunar stroke was 0.725 (95％ confidence interval 0.671-0.776;P ＜ 0.001);the optimal cut-off value was 2.32,the sensitivity of predicting END was 61.21％,and the specificity was 72.54％.Conclusion The elevated NLR after admission is an independent risk factor for END in patients with lacunar stroke,which has certain value for early identification and prediction of END.
