Abstract TMP80: Sex Is Associated With Location, Severity And Outcome Of Intracerebral Hemorrhage: A Combined Analysis Of Four Landmark Studies

Background and objective: Small, single-center studies point to biological and clinical differences in women and men who sustain a spontaneous, non-traumatic intracerebral hemorrhage (ICH). Leveraging data from four landmark studies of ICH, we investigated the impact of sex on risk factors, location, severity and outcome of ICH. Design: Individual patient data meta-analysis of four studies of ICH, including three randomized clinical trials and one multi-ethnic observational study. Setting: Academic medical centers in the United States. Patients: Patients with neuroimaging confirmed ICH. Measurements: We conducted an individual patient data meta-analysis of four landmark studies of ICH: ERICH, ATACH-II, FAST and MISTIE-III. We evaluated whether sex was associated with specific risk factor profiles, hemorrhage location (deep or lobar), neuroimaging severity (hematoma volume and expansion), and poor 90-day functional outcomes (defined as a modified Rankin scale 4 to 6). Main Results: A total of 4,812 ICH patients were evaluated (mean age 62, 60% males). Men with ICH were younger, more likely to be smokers and diabetics, and less likely to be on anticoagulants (all p Conclusions: Men with ICH are more likely to have vascular risk factors, have larger hemorrhage volumes, and have higher risk of hemorrhage expansion. They are also more likely to have a good outcome at 90 days compared to women.
