目的探讨ABCD评分和ABCD2评分在短暂性脑缺血发作中的应用价值。方法按照ABCD评分法和ABCD2评分法评分,观察2 d内、7 d内脑梗死的发生率。结果97例TIA患者2 d内脑梗死的发生率为19.6%;7 d内脑梗死的发生率为30.9%。预测2 d卒中风险时,ABCD评分法与ABCD2评分法的ROC曲线下面积(95%CI)分别为0.61(0.47～0.75)和0.71(0.57～0.84);预测7 d卒中风险时,ABCD评分法与ABCD2评分法的ROC曲线下面积(95%CI)分别为0.62(0.50～0.74)和0.74(0.62～0.85)。结论ABCD2评分法可能优于ABCD评分法。
Objective To investigate the value of ABCD score and ABCD2 score in transient ischemic attack. Methods According to ABCD score and ABCD2 score, the incidence of cerebral infarction within 2 days and 7 days was observed. Results The incidence of cerebral infarction in 97 cases of TIA within 2 days was 19.6%. The incidence of cerebral infarction within 7 days was 30.9%. The area under the ROC curve (95% CI) of ABCD score method and ABCD2 score method were 0.61 (0.47-0.75) and 0.71 (0.57-0.84) respectively when predicting the stroke risk at 2-day. In predicting the stroke risk at 7-day, ABCD score The area under the ROC curve (95% CI) with ABCD2 score was 0.62 (0.50-0.74) and 0.74 (0.62-0.85), respectively. Conclusion ABCD2 score method may be superior to ABCD score method.
