Abstract:
Objective To evaluate the predictive value of ABCD3-I score for early stroke risk after transient ischemic attack (TIA). Methods A total of 136 consecutive patients with TIA admitted to the Department of Neurology,the First Hospital of Shangqiu from January 2010 to December 2012 were enrolled. The clinical data,medical history and image findings of the patients were collected. The incidence of stroke was observed within 90 days. The occurrence of stroke risk after TIA were scored with the ABCD2 and ABCD3-I. Logistic regression analysis was used to analyze the impact of risk factors for early stroke after TIA. The area under the curve (AUC)of receiver operating characteristic was used to compare the predictive values of the two kinds of scores. Results Of the 136 eligible patients with TIA,19 cases (14. 0%)had cerebral infarction within 90 days after TIA. There were no death and hemorrhagic stroke. The results of multivariate regression analysis showed that the duration of TIA≥60 min (OR,1. 060,95%CI 1. 012-1. 112)was an independent risk factor for early progressing stroke after TIA (P<0. 05). In the ABCD2 scoring model for risk stratification of low-,moderate-,high-risk groups,the incidences of stroke within 90 days were 5. 6%(4/72),18. 5%(10/54),and 50. 0%(5/10),respectively. In the ABCD3-I score model for risk stratification of low-,moderate-,high-risk groups,the incidences of stroke within 90 days were 0,7. 1%(6/84),and 52. 0%(13/25),respectively. In the low-,moderate-,high-risk groups,there were significant differences in the incidences of stroke in 90 days between the ABCD3-I and ABCD2 scoring models (P<0.01). The AUC of ABCD3-I score (0. 839,95%CI 0. 766-0. 896)was higher than that of ABCD2 score (0.783,95%CI 0. 704-0. 849;P<0. 01). Conclusion The ABCD3-I score may effectively predict the risk of early stroke after TIA,and its accuracy is better than ABCD2 score.
