Tan评分对老年AIS患者再发梗死的预测价值

Predictive Value of Tan Score for Recurrent Infarction in Elderly Patients with AIS

本文探讨CT大脑中动脉区域侧支评分系统--Tan评分在老年急性缺血性脑卒中(AIS)患者再发梗死方面的预测价值。选取老年AIS患者140例,其中33例再发梗死(观察组),107例未再发梗死(对照组),观察两组临床资料、实验室指标、Tan评分等差异。结果显示,观察组年龄明显高于对照组(P<0.05);观察组纤维蛋白原(Fib)、Tan评分≤1分比例明显高于对照组,而大脑中动脉血流速度明显低于对照组(P<0.05);Tan评分与大脑中动脉血流速度呈正相关(r=0.485,P<0.05);Logistic回归结果显示:年龄、大脑中动脉血流速度及Tan评分是老年AIS患者再发梗死的影响因素(P<0.05);Tan评分预测再发梗死的ROC曲线下面积为0.685(P<0.05),灵敏性和特异性分别为76.00%和67.50%。因此,可以通过CT大脑中动脉区域侧支评分系统Tan评分来预测老年AIS患者再发梗死的发生。

This paper discussed the predictive value of CT middle cerebral artery regional collateral scoring system-Tan score for recurrent infarction in elderly patients with acute ischemic stroke(AIS).140 elderly AIS patients were selected,including 33 patients with recurrent infarction(observation group)and 107 patients without recurrent infarction(control group),the differences of clinical data,laboratory indexes and Tan score between the two groups were observed.The age of the observation group was significantly higher than that of the control group(P<0.05).Compared with the control group,the proportion of fibrinogen(FIB)and Tan score≤1 in the observation group were higher(P<0.05),while the blood flow velocity of middle cerebral artery in the observation group were lower(P<0.05).Tan score was positively correlated with middle cerebral artery blood flow velocity(r=0.485,P<0.05).Logistic regression showed age,middle cerebral artery blood flow velocity and Tan score were the influencing factors of recurrent infarction in elderly AIS patients(P<0.05).The area under ROC curve of recurrent infarction predicted by Tan score was 0.685,P<0.05,and the sensitivity and specificity were 76.00%and 67.50%respectively.CT middle cerebral artery regional collateral scoring system Tan score has certain application value in predicting recurrent infarction.
