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.
