RESUMO
Objective To investigate the incidence of white matter lesions(WML) in acute ischemic stroke ,and to analyze its the risk factors .Methods Totally 248 cases of acute ischemic stroke patients were selected ,patients′general information were in‐vestigated ,the WML severity with Fazekas rating scale were evaluated and patients were divided into severe group and no severe group according to the results ,the differences of general information between two groups were compared ,the severe WML was set as dependent variable ,the risk factors were ananlzed by multiariable Logistic regression analysis .Results There were 106 cases se‐vere WML patients among 248 cases acute ischemic stroke ,the incidence was 42 .74% ;single factor analysis found that the age in severe group was significantly higher than non severe group ,the incidence of hypertension ,diabetes in severe group was significantly higher than non severe group ,the difference was statistical significance (P<0 .05);multiariable Logistic regression analysis showed that age (OR=4 .116 ,95% CI:1 .816-6 .454 ,P=0 .000) ,hypertension (OR=1 .462 ,95% CI:0 .842-1 .946 ,P=0 .026) and dia‐betes (OR=1 .157 ,95% CI:0 .698-1 .673 ,P=0 .038)were the independent risk factors of severe WML in acute ischemic stroke . Conclusion The incidence of severe WML in acute ischemic stroke patients is high ,we need to targeted prevention measures on ol‐der age ,hypertension ,diabetes mellitus patients to reduce severe WM L occurred .
