Study on relationship between anticardiolipin antibody and cerebrovascular diseases

Summary: Serum anticardiolipin antibody (ACA) was measured in 91 patients with cerebral infarction (CI), 42 patients with cerebral hemorrhage (CH) and 30 healthy controls. The results showed that the ACA in CI and CH patients was significantly higher than in controls and IgG ACA was the most important isotype. Stroke in ACA positive group tended to be recurrent and of multi focuses. Positive rate of IgG ACA reached its peak within the first week after stroke onset. The results suggested that ACA was an independent risk factor in CI and CH and might be valuable in stroke prediction.
