Abstract Objective: To compare the value of ABCD2 score combined with transcranial Doppler (TCD) or magnetic resonance angiography (MRA) in the recent development of cerebral infarction in patients with transient ischemic attack (TIA). Methods: 70 patients with TIA hospitalized in the department of neurology of our hospital from June 2015 to June 2017 were given ABCD2 score, 40 patients underwent TCD, and 30 patients underwent MRA. Cranial MRI examination was performed within 7 days of onset of TIA, the incidence of cerebral infarction was evaluated. Results: Among the 70 patients, 42 cases were ABCD2 scoring low-risk patients. The incidence of cerebral infarction was 4.76% . Among the 20 patients with moderate risk, the incidence of cerebral infarction was 45%. High-risk patients were 8 cases, the incidence of cerebral infarction was 62.50%. The incidence of cerebral infarction in high-risk group and high-risk group was significantly higher than that in low risk group (P<0.01), and there was no significant difference in the incidence of cerebral infarction between the 2 groups (P>0.05). ABCD2 score combined with TCD or MRA on TIA patients with recent cerebral infarction occurred under the diagnostic curve area AUC were 0.848 and 0.654, and the difference between the two tests was statistically significant (Z=2.43, P=0.015). Multivariate logistic regression analysis showed that hypertension, LDL≥2.6mol/L, symptom duration ≥60 min were positively correlated with cerebral infarction formation within 7 days after TIA. Conclusion: ABCD2 score has a good predictive value for short-term cerebral infarction in TIA. Compared with TCD, ABCD2 score combined with MRA can improve the accuracy of predicting the risk of cerebral infarction.
