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 AUC(ROC) 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.
