Objective: To assess the incidence, types and risk factors of atherothrombotic events (AT) within 7 days after transient ischemic attack (TIA) with ABCD2 Score in Chinese patients.

Methods: With ABCD2 Score, we retrospectively reviewed the medical records of 198 TIA patients, which met the inclusion criteria of our study. They were divided into a low risk group (ABCD2 < or = 3) and a moderate-high risk group (ABCD2 > or = 4) and the incidence, types and risk factors of AT within 7 days after TIA were evaluated and compared respectively with chi(2) test between the two groups. Statistic significance was considered as P < 0.05.

Results: The order of the frequency of accompanying diseases was hypertension 68.18% (135/198), diabetes 23.74% (47/198), coronary artery disease 21.72% (43/198), ischemic stroke 15.66% (31/198) and hyperlipemia 12.63% (25/198). AT within 7 days after TIA was observed in 6.19% (6/97) of the patients in the low risk group, all of them were suffering from TIA recurrence. In the moderate-high risk group, 14.85% (15/101) of the patients experienced AT, including 2 cases of TIA recurrence, 10 cases of ischemic stroke, 1 case of both TIA recurrence and ischemic stroke, 1 case of angina pectoris and 1 case of myocardial infarction. There was no peripheral vascular disease or death from vascular disease. Incidence of AT within 7 days in the moderate-high risk group was significantly higher than that in the low risk group (51.70% vs 27.27%, P < 0.05).

Conclusion: TIA patients with ABCD2 > or = 4 are at higher risk of AT within 7 days after TIA onset.
