Abstract

Background: Both the υ2 and υ4 alleles of the apolipoprotein E gene (APOE) have been reported to be overrepresented in lobar intracerebral hemorrhage and to be associated with cerebral amyloid angiopathy (CAA). These studies were performed primarily on the North American population and investigated in partly selected patient cohorts. Methods: 193 consecutive patients suffering from primary intracerebral hemorrhage (ICH) were included in our study. The localization of the ICH, i.e. cortico-subcortical, deep white matter, basal ganglia, brainstem and cerebellum, was put in relation to the APOE genotype and vascular risk factors. In 101 of these patients, the APOE genotype was also correlated to the presence and distribution of microbleeds and other microangiopathy-related damage, as shown by magnetic resonance imaging (MRI). Results: We found neither an association of a specific APOE genotype with ICH localization nor with microangiopathy-related MRI findings. Conclusions: In our study of an unselected Central European population, the APOE genotype was not confirmed as a candidate for providing additional diagnostic and potentially prognostic information in patients with ICH.
