[The application of ABCD2 Score in evaluation of the prognosis in transient ischemic attack]

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.

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.

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).

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