H. Hassaballa et al., Ischemic stroke outcome - Racial differences in the trial of danaparoid inacute stroke (TOAST), NEUROLOGY, 57(4), 2001, pp. 691-697
Objective: To determine racial differences in baseline stroke risk factors
and other measures in the Trial of ORG 10172 in Acute Stroke Therapy (TOAST
). Differences in these factors could influence response to acute stroke th
erapy and overall stroke outcome. Methods: The authors compared baseline de
mographic, medical, stroke, physical examination, CT, laboratory, and neuro
logic factors among 292 African-American and 801 white patients who enrolle
d in the TOAST study. TOAST compared danaparoid (ORG 10172) with placebo am
ong acute ischemic stroke patients who were treated within 24 hours of stro
ke onset. Results: African-Americans were younger and more frequently had h
ypertension, diabetes mellitus, congestive heart failure, and prior strokes
. In addition, African-Americans had higher mean diastolic blood pressure,
more lacunar strokes, and more severe prestroke disability. There were no s
ignificant differences between African-Americans and white patients in outc
omes at 7 days, overall number of adverse experiences, or occurrence of ser
ious bleeds or hemorrhagic transformations. However, there was a trend towa
rd a higher rate of favorable outcomes in white patients at 7 days. There w
as no significant difference in very favorable outcome at 3 months between
African-American and white patients, but significantly more white patients
had favorable outcome at 3 months. Conclusion: Although African-Americans p
ossess a number of factors that should predict higher rates of poor stroke
outcome after acute therapy, they have the capacity to respond similarly to
white patients after acute stroke therapy. Perhaps younger age and presenc
e of lacunar infarction are stronger predictors of good outcomes than was a
ppreciated previously.
