The prevalence of clinically significant CAS varies significantly by race. Native American and Caucasian individuals have the highest prevalence of CAS, whereas African American males and Asian females appear to have the lowest prevalence. This information adds evidence to the hypothesis that the increased stroke rate in African American subjects is likely not related to extracranial cerebrovascular disease. Furthermore, this is a novel report of an extremely high prevalence of CAS in the Native American population.
