应用ABCD^2评分预测眩晕患者脑梗死风险

Predictive Value of ABCD^2 Scale in Cerebral Infarction Among Patients with Vertigo

目的探讨ABCD2评分对眩晕患者脑梗死事件的预测价值。方法收集2010年1月至2012年10月解放军第252医院收治的眩晕患者268例,根据有无脑梗死分为脑梗死组和无脑梗死组,对患者行ABCD2评分,分析组间年龄、血压、临床特征、症状持续时间和糖尿病史的差异,绘制ROC曲线。结果脑梗死组就诊时血压≥140/90 mm Hg、肢体无力比例显著高于无脑梗死组(P<0.05),脑梗死组ABCD2评分显著高于无脑梗死组(P<0.05)。利用ROC曲线,以ABCD2评分来预测脑梗死情况,曲线下面积为0.90,P=0.000,95%CI为0.835~0.966,Cutoff值为4.5分。结论ABCD2评分可对眩晕后脑梗死风险进行预测,对预防脑卒中的发生、改善预后至关重要。

Objective To evaluate the predictive value of ABCD2 scoring in cerebral infarction among patients with vertigo. Methods Two hundred and sixty-eight patients with vertigo admitted to PLA No. 252 Hospital from January 2010 to October 2012 were recruited, and divided into cerebral infarction group and non-cerebral infarction group. ABCD2 scores were assigned. The age, level of blood pressure, clinical fea- tures, duration of symptoms and history of diabetes were collected and compared between the two groups, the cutoff level of ABCD2 scale for anticipating cerebral infarction risk was evaluated according to receiver operat- ing eharaeteristic（ROC） eurve. Results Patients in the cerebral infaretinn group had significantly higher percentage of patients with blood pressure/〉 140/90 mm Hg, unilateral weakness, as eompared with patients in the non-cerebral infarction group（ P 〈 O. 05 ）. Patients with cerebral infarction had higher ABCD2 scores than those without cerebral infarction（ P 〈0.05 ）. According to the ROC curve,area under curve was O. 90 of ABCD2 scale for anticipating ccrehral in[＇aretion risk,P = O. 000,95% confidence interval （ CI ） was 0. 835- O. 966 and the cutoff level of ABCD2 scale tbr anticipating cerebral inlarction risk was 4.5. Conclusion The ABCI）2 score, ean he used to predict cerebral infarction event among patients with vertigu,whieh is important for the preventinn aml impruving the prognosis of stroke.
