ABSTRACT
Objective Cerebral infarction is characterized by high morbidity, high mortality and high disability. The aim of this study is to explore the correlation between neutrophil lymphocyte ratio and acute cerebral infarction(ACI), providing references for the prevention and treatment of ACI.Methods In this study, 111 patients with ACI admitted to the Department of Neurology of Jiangsu Provincial People′s Hospital from April 2017 to October 2017 were enrolled in the retrospective analysis and divided into 3 subgroups according to the infarct size: small area ACI group (diameter3.0 cm, n=31). A number of 107 healthy subjects were included as control group. Baseline data and blood test indicators were collected and compared between groups.Results Compared with the control group, the level of sex, smoking, drinking, hypertension, diabetes, hyperlipidemia, white blood cells, neutrophils and NLR in patients with acute cerebral infarction were higher（all P<0.05）. The white blood cell count and NLR of large area group were higher than those of small area and medium area group. The white blood cell count and NLR of large area group were higher than those of small area and middle area group, and the difference was statistically significant. Multivariate logistic regression analysis showed that smoking (OR=3.468, P=0.003), hypertension (OR=8.764, P=0.000), hyperlipidemia (OR=2.867, P=0.020), and NLR (OR=3.016, P=0.000) were risk factors for acute cerebral infarction. The area under the ROC curve of neutrophil lymphocyte ratio was 0.773, and the best diagnostic value was 2.13.Conclusion NLR is a risk factor for ACI, and has a predictive effect on the occurrence of ACI.
