应用ABCD2评分法预测短暂性脑缺血发作患者进展为脑梗死的临床研究

目的评估ABCD2评分法对短暂性脑缺血发作(TIA)患者短期内进展为脑梗死的预测价值。方法选择TIA患者120例,依据是否发展为脑梗死,分为脑梗死组32例和非脑梗死组88例,采用ABCD2评分标准对患者进行评分,并分为低危组(0～3分,38例)、中危组(4～5分,71例)和高危组(6～7分,11例),观察患者7 d内脑梗死的发生率。结果低危组、中危组和高危组患者7 d内发生脑梗死的比例分别为2.6%、32.4%和72.7%,3组比较差异有统计学意义(P0.05)。与非脑梗死组比较,脑梗死组年龄≥60岁、入院时血压≥140/90 mm Hg(1 mm Hg=0.133 kPa)、出现肢体无力、脑缺血症状持续时间≥10 min、有糖尿病史患者比例明显增高,差异有统计学意义(P0.05)。结论 ABCD2评分标准是临床预测TIA短期内进展为脑梗死比较有效的一种方法。

Clinical study on using ABCD2 score in predicting evolution of patient with transient ischemic attack into cerebral infarction

Objective To explore the ability of ABCD2 score in predicting transient ischemic attack (TIA) to evolve into cerebral infarction.Methods 120 TIA patients were evaluated according to ABCD2 criteria.The occurrence of cerebral infarction was observed in 7 days.Results The 7-day risk of stroke was 2.6% in patients with an ABCD2 score of low risk(0 —3) ,32.4% with a score of moderate risk(4 —5) ,and 72.7% with a score of high risk(6 — 7).Conclusions ABCD2 criteria is effective for predicting the occurrence of cerebral infarction after short time of TIA.
