RESUMO
Objective To investigate the value of ABCD3-I score in predicting the outcome of acute minor ischemic stroke. Methods Totally 255 patients were valued by ABCD, ABCD2, ABCD3, ABCD3-I and ESSEN score then the clinical characters, outcome and early progression of these patients were investigated. Results Forty-eight patients had poor outcome after 90 days. Univariate logistic regression indicated that the differences of hypertension, diabetes, cardiovascular disease, stenosis of criminal artery, abnormal signal in diffusion weighted imaging (DWI) and other clinical symptoms between poor outcome group and good outcome group were statistically significant (P<0.05). The AUC of ABCD, ABCD2, ABCD3, ABCD3-I and ESSEN score in predicting outcome of acute minor stroke was 0.791 0, 0.798 3, 0.827 9, 0.930 0 and 0.735 9 respectively. There was difference among patients with different ABCD3-I scores both in outcome and early progression. Conclusion ABCD3-I score can predict the outcome of acute minor stroke and supply a new method for personalized treatment.
RESUMO
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.
RESUMO
Objective To assess the ability of ABCD3-Ⅰ score in evaluating the early risk of cerebral infarction after transient ischemic attack ( TIA ).Methods A total of 107 TIA patients were evaluated according to ABCD2,ABCD3 and ABCD3-Ⅰ criteria.The occurrences of cerebral infarction within 2 days and 7 days were observed.Results The AUCRoc of ABCD2,ABCD3 and ABCD3-Ⅰ were 0.61,0.66 and 0.71 in predicting the risk of cerebral infarction within 2 days,and were 0.62,0.68 and 0.74 in predicting within 7 days,respectively.Among 107 patients with TIA,13 evolved into cerebral infarction within 2 days,accounting for 12.1％,and 24 within 7 days,accounting for 22.4％.According to ABCD3-Ⅰ criteria,17 patients were of low risk scored 0-3 ; 54 patients were of medium risk scored 4-7 ; and 36 patients were of high risk scored 8-13.The different incidence of cerebral infarction after TIA was related to ABCD3-Ⅰ score:the higher the score was,the higher incidence was.Except for age factor,every score item of ABCD3-Ⅰ display obvious influence to the occurrence of cerebral infarction within 2 days and 7 days after TIA (P ＜ 0.05 ).Conclusion ABCD3-Ⅰ criteria could more effectively predict the occurrence of early risk of cerebral infarction after TIA,which could be used in regular clinical practice for assistance in TIA risk stratification and treatment.
