Clinical features of ischemic stroke in Hispanics and non-Hispanic whites in New Mexico: a study of 341 consecutive patients at two hospitals.

This study was undertaken to determine whether there are any differences in the clinical features of ischemic stroke between Hispanics and non-Hispanic whites in New Mexico. From August 1988 to August 1990, one investigator prospectively evaluated consecutive patients who presented within 30 days of onset of stroke or transient ischemic attack and entered data into a computerized stroke registry. Several important vascular factors were recorded. Patients presented to either a Veterans Affairs Medical Center or a University Medical Center (a county facility). There were 112 Hispanics and 229 non-Hispanic whites with ischemic stroke or transient ischemic attack. Non-Hispanic whites were more likely to have ischemic heart disease (P = .01) and ischemic (vs nonischemic) causes of potential cardiogenic emboli (p = .05) than were Hispanics. The following were not significantly different between Hispanics and non-Hispanic whites: prevalence of vascular risk factors, death within 30 days of stroke, vascular territory involved, infarct location, prevalence of extracranial carotid stenosis, or cardiac sources of emboli. Our study does not show an obvious difference in the clinical features of ischemic stroke between Hispanics and non-Hispanic whites in New Mexico.
