【摘要】 目的 探讨脑小血管病(cerebral small vessel disease,CSVD)患者存在颅内大动脉狭窄的危险因素,并构建预测评分系统。方法 收集 2020-01—2021-06 于唐山市工人医院神经内科就诊的 CSVD 患者,根据头颈 MRA 检查评估有无颅内大动脉狭窄并分组。通过二元 Logistic 回归探索 CSVD 患者存在颅内大动脉狭窄的独立危险因素,根据回归系数对各因素进行赋分,建立预测评分系统,并绘制受试者工作特征曲线(receiver operating characteristic curve,ROC 曲线)评价其预测效能。结果 共纳入 799 例患者,回归分析显示,年龄、糖化血红蛋白、CSVD 总负荷、血浆同型半胱氨酸水平>15 umol/L、既往脑卒中史为 CSVD 患者存在颅内大动脉狭窄的独立危险因素,根据回归系数建立了总分为 20 分的预测评分系统,选择约登指数最大者作为预测截断值即 8 分,曲线下面积(area under the curve,AUC)为 0.809(95%CI:0.762~0.855,P<0.001)。结论 基于年龄、糖化血红蛋白、CSVD 总负荷、血浆同型半胱氨酸水平及既往卒中史建立的评分系统能有效预测 CSVD 患者是否存在颅内大动脉狭窄。

【Abstract】 Objective cerebral small vessel disease( To investigate the risk factors of large intracranial artery stenosis in patients with CSVD),and to construct a predictive scoring system. Methods The study was carried out in Tangshan city,Hebei Province. Patients with CSVD who visited the Neurology Department of Tangshan Gongren Hospital from January 2020 to June 2021 were collected and divided into two groups according to whether they suffered from large intracranial artery stenosis. Binary Logistic regression models were used to discuss the independent risk factors for large intracranial artery stenosis in patients with CSVD,then assigned scores to each factor according to the regression coefficient,established and evaluated the predictive efficiency of the prediction scoring system by the receiver operating characteristic curve(ROC curve). Results A total of 799 patients were enrolled,and regression analysis showed that age,HbA1c,total CSVD burden,plasma homocysteine levels > 15umol/L,previous stroke were independent risk factors. On this basis,a total score system of 20 points was established and the highest Jordon index(8 points)was selected as the cut-off value. The area under the ROC curve(AUC)was 0.809(95% CI:0.762~0.855,P<0.001). Conclusion The scoring system established based on age,HbA1c,total CSVD burden,plasma homocysteine levels and previous stroke history can effectively predict the occurrence of large intracranial artery stenosis in patients with CSVD.
