ABCD2评分对短暂性脑缺血发作患者发生脑梗死风险的评估价值

目的探讨ABCD2评分对短暂性脑缺血发作(TIA)患者发生脑梗死风险的评估价值。方法对病程<7 d的220例TIA患者应用ABCD2评分分为低危组(0～3分)和中-高危组(4～7分),观察并比较两组患者TIA发病7 d、6个月、1年内脑梗死的发生率。结果根据ABCD2评分,108例患者归为低危组,112例归为中-高危组。TIA发病7 d、6个月及1年内低危组脑梗死发生率分别为4.6%、6.5%及7.4%,中-高危组脑梗死发生率分别为18.8%、27.7%及33.9%;中-高危组TIA发病7 d、6个月及1年内脑梗死发生率显著高于低危组(均P<0.05)。结论 ABCD2评分是临床上预测TIA患者发生脑梗死的有效方法。

Value of risk evaluation of cerebral infarction in patients with transient ischemic attack by ABCD2 score

Objective To explore the value of ABCD2 score to evaluate the risko of cerebral infarction in patients with transient ischemic attack(TIA).Methods Two hundred and twenty TIA patients were evaluated by ABCD2 score at 7 d after TIA onset,and divided into low risk group(0-3 scores) and moderate-high risk group(4-7 scores).The incidences of cerebral infarction in 7 d,6 months and 1 year after TIA onset were observed and compared between the two groups.Results According to the ABCD2 score,there were 108 patients in the low risk group and 112 patients in the moderate-high risk group.The incidences of cerebral infarction in 7 d,6 months and 1 year after TIA onset were 4.6%,6.5% and 7.4% in the low risk group,respectively;while,18.8%,27.7% and 33.9% in moderate-high,respectively.The incidences of cerebral infarction in moderate-high risk group in 7 d,6 months and 1 year after TIA onset were significantly higher than those in low risk group(all P<0.05).Conclusion ABCD2 score is effective to predict the incidence of cerebral infarction in TIA patients.
