Abstract 382: Racial and ethnic differences in risk factors, etiologies and outcomes in young patients with intracerebral hemorrhage

To evaluate racial and ethnic differences in risk factors, etiologies and outcomes in young patients with intracerebral hemorrhage (ICH). Racial and ethnic disparities in risk factors, etiologies and outcomes for young patients with ischemic stroke (AIS) are well described. Less is known about racial and ethnic disparities for young patients presenting with ICH. As ICH is associated with higher short‐term and long‐term mortality than AIS and has a rising incidence, it is important to review disparities in its evaluation and management. We identified patient aged 18‐50 from our stroke registry with non‐traumatic ICH from 10/2016 to 11/2019. Baseline characteristics were abstracted, and ICH risk factors, etiologies and outcomes were compared between racial and ethnic groups. Independent samples t‐test and chi‐squared test were utilized for continuous and categorical outcomes, respectively. All tests were two‐tailed and the error rate was set at 5%. Among 619 patients in the study, 29% were non‐Hispanic White (NHW), 32% non‐Hispanic Black (NHB), 31% Hispanic (HIS), 5% Asian, and 4% other. HIS were least likely to be insured (51.9%) compared to NHB (66.7%) and NHW (71.2%). NHB were most likely to be single (54.4%) and living alone (20.5%). HIS were more likely not to not have a primary care provider (60.8%; p<0.01). NHB had a greater arrival systolic blood pressure (180.2 vs. 163.2, p<0.01) and diastolic blood pressure (103.9 vs 94.8, p<0.01), compared to NHW. Prior history of hypertension (69.7%) and diastolic dysfunction on ECHO (24.6%) was more prevalent in NHB, compared to NHW and HIS. NHB had the greatest incidence of moderate (17.4%) to severe (15.4%) left ventricle (LV) hypertrophy, and three times greater odds than NHW to have at least moderate LV hypertrophy. Hypertensive etiology for ICH was most prevalent in NHB (65.1%, p<0.01) compared to NHW (46.9%) and HIS (52.9%). Although we did not find significant differences in measured outcomes, our study demonstrates underlying sociodemographic and clinical risk factors which may underlie racial and ethnic disparities for young patients with ICH.
