Ischemic stroke subtype distribution was compared between Mexican Americans (MAs) and non Hispanic whites (NHWs) in a community based stroke surveillance study in Nueces County,TX. Therewas no difference in the distribution of stroke subtype by ethnicity (p = 0.19). There was a similar proportion of small vessel and large artery strokes between the two ethnic groups (p = 0.32). Differences in stroke rates among MAs and NHWs are not explained by the distribution of ischemic stroke subtypes.
