目的探讨ABCD3-I评分法对预测短暂性脑缺血发作患者早期脑卒中风险的价值。方法短暂性脑缺血发作患者120例,分别采用ABCD2、ABCD3、ABCD3-I评分法对患者进行评分,并观察患者7 d内出现脑梗死的几率。结果 ABCD3-I评分法的95%CI、ROC曲线下面积以及OR值的预测情况均明显优于ABCD2和ABCD3评分法,差异具有统计学意义(P<0.05)。在短暂性脑缺血发作的7 d内出现脑梗死的几率为20.83%。ABCD3-I评分下低危、中危和高危患者发生脑梗死的几率分别为0、9.10%和33.33%,该评分与脑梗死发生率呈正相关(r=0.51)。结论 ABCD3-I评分法与其他评分法相比,能够更有效的预测短暂性脑缺血患者早期脑卒中出现的风险,具有非常重要的临床价值,值得推广使用。
Objective To investigate the value of ABCD3-I score in predicting the early stroke risk in patients with transient ischemic attack. Methods One hundred and twenty patients with transient ischemic attack were scored by ABCD2, ABCD3 and ABCD3-I scoring methods, and the incidence of cerebral infarction was observed within 7 days. Results The 95% CI of the ABCD3-I scoring method, the area under the ROC curve and the prediction of OR were significantly better than those of the ABCD2 and ABCD3 scoring methods. The difference was statistically significant (P <0.05). The incidence of cerebral infarction within 7 days of transient ischemic attack was 20.83%. The risk of cerebral infarction was 0, 9.10% and 33.33% in ABCD3-I scoring patients with low, medium and high risk respectively. The score was positively correlated with the incidence of cerebral infarction (r = 0.51). Conclusion Compared with other scoring methods, ABCD3-I scoring method can more effectively predict the risk of early stroke in patients with transient ischemic injury, which has a very important clinical value and is worth promoting.
