ABCD3-V评分法对短暂性脑缺血发作早期发生脑梗死的预测价值

目的:探讨应用ABCD3-V评分法对短暂性脑缺血发作(TIA)患者早期发生脑梗死的预测价值。方法:选取TIA患者212例,观察7 d内脑梗死的发生率。通过受试者工作特征(ROC)曲线下面积(AUC)评估ABCD3-V评分对TIA后发生脑梗死的预测价值。根据ABCD3-V评分,所有患者分为低危组、中危组、高危组,分析相关危险因素。结果:212例TIA患者7 d内发生脑梗死27例(12.7%)。ABCD2、ABCD3与ABCD3-V评分法预测TIA后7 d内脑梗死风险的AUC分别为0.671、0.729、0.808。高危组脑梗死的发生率大于低危组与中危组(P0.01,P0.05),中危组脑梗死的发生率大于低危组(P0.01)。ABCD 3-V评分与7 d内脑梗死发生率呈正相关(r=0.945,P0.01)。结论:ABCD3-V评分法能有效地预测TIA患者早期发生脑梗死的风险。

Predictive Significance of ABCD3-V Score for Cerebral Infarction Occurrence Early after Tran-sient Ischemic Attack

Objective: To explore the value of ABCD3-V score in predicting the risk of cerebral infarction early after transient ischemic attack (TIA). Methods: Two hundred and twelve TIA patients were enrolled. The inci-dence of cerebral infarction within 7 days after TIA was observed.The predictive ability of ABCD3-V score was as-sessed by calculating the area under the Receiver Operating Characteristic (ROC) curve (AUC). According to ABCD3-V score, the patients were divided into low risk group, medium risk group and high risk group. Then the related risk factors were analyzed. Results: 27 (12.7%) of 212 patients suffered from cerebral infarction within 7 days after TIA. The AUC for ABCD2, ABCD3 and ABCD3-V were 0.671, 0.729 and 0.808 in predicting the risk of cerebral infarction within 7 days after TIA, respectively. The incidence of cerebral infarction was significantly high-er in the high risk group than in medium and low risk groups(P<0.01, P<0.05). The ABCD3-V score was positively related with the incidence of cerebral infarction within 7 days after TIA (r =0.945, P<0.01). Conclusion:ABCD3-V score could more effectively predict the risk of early occurrence of cerebral infarction after TIA.
