2、认知障碍的影响因素,并据其构建 ACI 继发血管性认知障碍的预测模型,采用 MedCalc11 4 绘制受试者工作特征曲线(OC)分析预测模型对 ACI 继发血管性认知障碍的预测价值,获取曲线下面积(AUC)。结果:多因素 Logis-tic 回归分析结果显示,年龄较大、合并颈动脉粥样硬化、合并高血压、合并糖尿病、脑白质疏松、梗死部位为额叶/颞叶/丘脑、卒中后抑郁、血清 Hcy 水平较高均为 ACI 患者继发血管性认知障碍的独立危险因素(O=3 827、2 713、3.501、3 271、3 010、2 192、4 764、2 672,P 0 05),受教育年限较长为 ACI 患者继发血管性认

4、因素包括年龄较大、合并颈动脉粥样硬化、合并高血压、合并糖尿病、脑白质疏松、梗死部位为额叶/颞叶/丘脑、卒中后抑郁、血清 Hcy 水平较高,保护因素为受教育年限较长,同时相关回归模型对 ACI 患者继发血管性认知障碍的预测价值较好,临床可据此对 ACI 患者继发血管性认知障碍进行预测,降低 ACI 患者继发血管性认知障碍的风险。关键词急性脑梗死血管性认知障碍影响因素回归模型受试者工作特征曲线中图分类号:743文献标识码:Adoi:10.19381/j.issn.1001-7585.2023.03.004Construction and Analysis of egression Model fo
