However, the relationship between WMLs and transient ischemic attacks （TIAs） is not well established. This study aimed to determine the clinical significance of WMLs in patients with TIA. Methods： A total of 181 consecutive inpatients with first-ever TIA were enrolled. Brain MRls within 2 days of symptom onset were used to measure WML volumes. Recurrent vascular events within 1 year of TIA onset were assessed. The relationship between WMLs and recurrent risk of vascular events was determined by a multivariate logistic regression. Results： WMLs were identified in 104 patients （57.5%）. Age and ratio of hypertension were significantly different between patients with and without WMLs. The incidence of vascular events in patients with WMLs significantly increased in comparison to those without WMLs （21.15% vs. 5.19%, 95% confidence interval [CI]： 1.18-[ 5.20, P = 0.027） after controlling for cont／~unders. Furthermore, distributions of WML loads were found to be different between patients who developed vascular events and those who did not. WML volumes were demonstrated to be correlated with recurrent risks, and the fourth quartile of WML volumes led to an 8.5-fold elevation of recurrent risk of vascular events compared with the first quartile （95% CI： 1.52-47.65, P = 0.015） alier adjusting for hyperlipidemia. Conclusion： WMLs occur frequently in patients with T1A and are associated wiila the high risk of recurrent vascular events, suggesting a predictive neuroimaging marker for TIA outcomes.展开更多
