Abstract
OBJECTIVE: To investigate the influence of neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) on the severity and short-term prognosis of acute ischemic stroke (AIS). METHODS: A retrospective analysis was made on 188 AIS patients treated in our hospital from June 2019 to June 2021. They were divided into mild stroke group and severe stroke group based on NIHSS score. In view of the modified Rankin score (mRS) on 14th day after stroke, patients were divided into good prognosis group and bad prognosis group. The clinical data, NLR and MPV data of each group were compared, and the independent risk factors of short-term poor prognosis of AIS patients were analyzed by multivariate Logistic regression. RESULTS: NLR and MPV in patients with mild stroke were lower than those with severe stroke (P<0.05). In addition, NLR and MPV of patients with good prognosis were lower than those with poor prognosis (P<0.05). Regression analysis revealed that high NLR and MPV were independent predictors of short-term poor prognosis of AIS patients. The AUC of NLR in predicting the poor prognosis of patients after 14 days of stroke was 0.904, and the specificity and sensitivity were 70.55% and 97.62%. A. AUC of MPV was 0.904, and the specificity and sensitivity were 92.47% and 85.71%. B. Pearson correlation analysis revealed that NLR was positively correlated with MPV (r=0.452, P<0.001). CONCLUSION: The elevation of NLR and MPV may be independent risk factors of AIS, but it is related to the severity of stroke and short-term prognosis. AJTR
