Acute Spontaneous Lobar Cerebral Hemorrhages Present a Different Clinical Profile and a More Severe Early Prognosis than Deep Subcortical Intracerebral Hemorrhages-A Hospital-Based Stroke Registry Study

Acute spontaneous intracerebral hemorrhage (ICH) is the most severe stroke subtype, with a high risk of death, dependence, and dementia. Knowledge about the clinical profile and early outcomes of ICH patients with lobar versus deep subcortical brain topography remains limited. In this study, we investigated the effects of ICH topography on demographics, cerebrovascular risk factors, clinical characteristics, and early outcomes in a sample of 298 consecutive acute ICH patients (165 with lobar and 133 with subcortical hemorrhagic stroke) available in a single-center-based stroke registry over 24 years. The multiple logistic regression analysis shows that variables independently associated with lobar ICH were early seizures (OR 6.81, CI 95% 1.27-5.15), chronic liver disease (OR 4.55, 95% CI 1.03-20.15), hemianopia (OR 2.55, 95% CI 1.26-5.15), headaches (OR 1.90, 95% CI 1.90, 95% IC 1.06-3.41), alcohol abuse (>80 gr/day) (OR 0-10, 95% CI 0.02-0,53), hypertension (OR 0,41, 95% CI 0.23-0-70), sensory deficit (OR 0.43, 95% CI 0.25-0.75), and limb weakness (OR: 0.47, 95% CI 0.24-0.93). The in-hospital mortality was 26.7% for lobar and 16.5% for subcortical ICH. The study confirmed that the clinical spectrum, prognosis, and early mortality of patients with ICH depend on the site of bleeding, with a more severe early prognosis in lobar intracerebral hemorrhage.
