Key result
Black patients had a higher incidence of ischemic stroke than white patients, with small-vessel and undetermined strokes nearly twice as common, and large-vessel strokes 40% more common.
Why the study?
Does the incidence rate of ischemic stroke subtypes differ between blacks and whites?

Implication
Excess stroke burden in Black patients spans subtypes; challenges prior assumptions on large-vessel predominance in whites and leaves open targeted prevention.

Population
1956 first-ever ischemic strokes among blacks and whites in a large, representative, biracial population (Greater Cincinnati/Northern Kentucky Stroke Study) between July 1, 1993, and June 30, 1994.

Outcome
Incidence rates of ischemic stroke subtypes (cardioembolic, large-vessel, small-vessel, other, and stroke of undetermined cause)hard clinical
Blacks have a higher incidence of small-vessel, undetermined, and large-vessel ischemic strokes compared to whites, indicating the excess stroke burden is not uniformly distributed across subtypes.
Cite This Study
Schneider et al. (2004) conducted an observational in Ischemic stroke (n=1,956). Black race vs. White race was evaluated on Incidence rates of ischemic stroke subtypes. Black patients had a higher incidence of ischemic stroke than white patients, with small-vessel and undetermined strokes nearly twice as common, and large-vessel strokes 40% more common.
