We investigated whether early hematoma or edema volumes could explain the a
dverse association between APOE epsilon 4 and survival in intracerebral hem
orrhage. Among 102 patients, epsilon 4 carriers had a higher mortality rate
than non-epsilon 4 carriers (38 versus 24%, p = 0.05). Nonsurvivors had la
rger hematoma (75.5 cm(3) versus 27.1 cm(3), p < 0.001) and edema volumes (
37.5 cm(3) versus 17.1 cm(3), p < 0.01), but these were not associated with
epsilon 4 after adjusting for race, age, and type of hemorrhage.
