[TOAST subtyping of acute ischemic stroke].

OBJECTIVE: To determine the etiological characteristics of ischemic stroke in Chinese people on the basis of Trial of Org 10 172 in Acute Stroke Treatment (TOAST) criteria. METHODS: 300 patients with ischemic stroke were recruited into this study. Ischemic stroke was classified into five subtypes based on clinical manifestations, MRI, MRA and DSA. RESULTS: Of all the ischemic stroke patients, 12.3%, 40.0%, 31.3%, 5.0%, and 11.4% were classified as cardio embolism, large-artery atherosclerotic, lacunare, of other demonstrated etiology and of undetermined etiology. CONCLUSIONS: The statistical comparison between male and female of each subtype is not significant. The relative incidence of large-artery atherosclerosis in Chinese patients is higher than that of all the other four subtypes.
