Abstract：Objective To investigate the values of the modified ABCD2 score and cephalocervical CTA to predicting short-term risk of stroke after transient ischemic attack (TIA). Methods The modified ABCD2 score and cephalocervical CTA were performed in 698 patients after TIA, in whom the plasma levels of lipoprotein associated phospholipase A2 (Lp-PLA2) were determined. All the patients were divided into low stroke risk, moderate stroke risk and high stroke risk groups according to the modified ABCD 2 score combined with the plasma levels of Lp-PLA2 and they were divided into normal vessel, mild vascular stenosis, moderate vascular stenosis and severe vascular stenosis groups according to the cerebrovascular stenosis degree shown by cephalocervical CTA. The cerebral infarct (ischemia stroke) was assessed by the imaging examination and clinical symptoms. Results Of 698 patients with TIA, 237 were in the low stroke risk group, 305 in moderate stroke risk group and 156 in high stroke risk group. Of 698 patients with TIA, 502 were in normal vessels group, 33 in mild vascular stenosis group, 77 in moderate vascular stenosis group and 86 in severe vascular stenosis group. The rate of stroke (34.0%) was significantly higher in the high risk group than those (16.0%and 24.6%respectively) in the low risk and moderate risk groups (P<0.05). The rate of severe vascular stenosis (55.1%) was significantly higher in the high risk group than those (13.9%and 25.2%respectively) in the low risk and moderate risk groups (P<0.05). The rate of multiple vessel stenosis (66.0%) was significantly higher in the high risk group than those (34.2%and 58.0%) in the low risk and moderate risk groups (P<0.05). Conclusion The modified ABCD2 score and CTA examination are of the important values to prediction of ischemia stroke risk in the patients after TIA.
