目的探讨采用ABCD2评分法预测短暂性脑缺血发作(TIA)进展为脑梗死的价值。方法按照Johnston等对TIA的ABCD2评分标准,测定148例TIA患者的评分,并观察其2、7、90 d内脑梗死的发生率。结果评分≤3分的TIA患者有69例,2、7、90 d发生脑梗死的例数分别为3例(4.3%)、5例(7.2%)、6例(8.7%);评分为4或5分的患者51例,2、7、90 d进展为脑梗死的例数分别为5例(9.8%)、8例(15.6%)和10例(17.6%);评分≥6分的患者28例,2、7、90 d进展为脑梗死的例数分别为8例(28.6%)、10例(35.7%)、13例(46.5%)。不同ABCD2评分值的TIA患者,其脑梗死发生率差异均有统计学意义(P均<0.05)。结论ABCD2评分值不同的TIA患者,脑梗死的发生率不同,分值越高,发生率越高。ABCD2评分标准是临床预测TIA短期进展为脑梗死的一种简便、有效的方法。
Objective To investigate the value of using ABCD2 score to predict the progression of transient ischemic attack (TIA) to cerebral infarction. Methods According to Johnston et al.’s ABCD2 score on TIA, 148 patients with TIA were scored and the incidence of cerebral infarction within 2, 7 and 90 days was observed. Results There were 69 cases of TIA with score ≤3, 3 cases (4.3%) with cerebral infarction at 2,7,90 days, 5 cases (7.2%) and 6 cases (8.7%) with score of 4 51 cases were diagnosed as cerebral infarction or 5 cases, and 5 cases (9.8%), 8 cases (15.6%) and 10 cases (17.6% The number of cases with cerebral infarction progressing in 28 cases at 2, 7 and 90 days was 8 cases (28.6%), 10 cases (35.7%) and 13 cases (46.5%), respectively. There were significant differences in the incidence of cerebral infarction between TIA patients with different ABCD2 scores (all P <0.05). Conclusions The incidence of cerebral infarction is different in TIA patients with different ABCD2 scores. The higher the score, the higher the incidence. The ABCD2 score is a simple and effective clinical prediction of the short-term progression of TIA to cerebral infarction.
