Background: Small vessel disease (SVD) is the underlying anatomical substrate for both lacunar infarction and subcortical hemorrhage. Aim: To assess predictive factors of ischemic or hemorrhagic stroke in patients with cerebral SVD. Materials and Methods: Prospective hospital-based stroke registry (“The Sagrat Cor Hospital of Barcelona Stroke Registry”) in an acute-care teaching hospital in Barcelona, Spain. From 4597 acute stroke patients included in the stroke registry over a 24-year period, 440 cases of lacunar stroke and 210 of subcortical intracerebral hemorrhage were selected. Demographics, clinical characteristics, risk factors, and early outcome were compared. Predictors of lacuna versus subcortical hemorrhage were assessed by multivariate analyses. Results: In a logistic regression model based on demographics, risk factors, clinical features and outcome, dyslipidemia (odds ratio [OR] 2.06 (95% confidence interval (CI) 1.17-3.62) and diabetes (OR 1.97, 95% CI 1.19–3.26) were independent risk factors for lacunar infarction. Anticoagulation therapy (OR 0.05, 95% CI 0.01–0.28), sudden onset (OR 0.51, 95% CI 0.33–0.78), motor symptoms (OR 0.44, 95% CI 0.26–0.76), headache (OR 0.23, 95% CI 0.12–0.41), altered consciousness (OR 0.10, 95% CI 0.05–0.21), respiratory complications (OR 0.19, 95% CI 0.08–0.46), and in-hospital death (OR 0.08, 95% CI 0.02–0.36) were predictors of subcortical hemorrhage. Conclusion: Identification of differential clinical and prognostic profile between ischemic and hemorrhagic consequences of underlying cerebral SVD is useful for risk stratification in the current process pursuing precision medicine.
