THURSDAY, June 2, 2022 (HealthDay News) -- Compared with White individuals, Black and Hispanic individuals have worse outcomes after certain types of stroke, according to a study published online June 1 in Neurology.
Laura Tarko, M.P.H., from the VA Boston Healthcare System, and colleagues examined the association of race and ethnicity with stroke mortality by stroke type in a retrospective observational study involving non-Hispanic White, non-Hispanic Black, and Hispanic patients with a first hospitalization for stroke between 2002 and 2012. Data were included for 37,790 stroke patients: 67, 26, and 7 percent were non-Hispanic White, non-Hispanic Black, and Hispanic, respectively.
The researchers found that Black patients experienced better 30-day survival than White patients after acute ischemic stroke (hazard ratio, 0.80) and worse 30-day survival after intracerebral hemorrhage (hazard ratio, 1.24). Compared with White patients, Hispanic patients experienced reduced risk for greater-than-one-year mortality after acute ischemic stroke (hazard ratio, 0.87) but had an increased risk for 30-day mortality after subarachnoid hemorrhage (hazard ratio, 1.61).
"Differences in mortality by race or ethnicity varied substantially when considering specific types of stroke, especially the different types of hemorrhagic stroke," a coauthor said in a statement. "If all types of stroke are considered together as one disease, it may mask underlying racial or ethnic disparities, since risk factors, such as age or blood pressure, and underlying social determinants of health, such as access to health care or structural racism, may vary differently between these outcomes."
