[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.
