Abstract

Highlights: A large population based cohort of patients with intracerebral hemorrhage was analyzed by surgically or conservatively treatment. Surgically treated patients on antiplatelet therapy had a higher risk to die in the hospital compared to non-antiplatelet users. No differences in in-hospital mortality for conservatively treated patients with or without antiplatelet therapy were observed. Abstract: Pre-treatment with antiplatelet agents is described to be a risk factor for mortality after spontaneous intracerebral hemorrhage (ICH). However, the impact of antithrombotic agents on mortality in patients who undergo hematoma evacuation compared to conservatively treated patients with ICH remains controversial. This analysis is based on a prospective registry for quality assurance in stroke care in the State of Hesse, Germany. Patients' data were collected between January 2008 and December 2012. Only patients with the diagnosis of spontaneous ICH were included ( International Classification of Diseases 10th Revision codes I61.0–I61.9). Predictors of in-hospital mortality were determined by univariate analysis. Predictors with P < 0.1 were included in a binary logistic regression model. The binary logistic regression model was adjusted for age, initial Glasgow Coma Score (GCS), the presence of intraventricular hemorrhage (IVH), and pre-ICH disability prior to ictus. In 8, 421 patients with spontaneous ICH, pre-treatment with oral anticoagulants or antiplatelet agents was documented in 16.3% and 25.1%, respectively. Overall in-hospital mortality was 23.2%. In-hospital mortality was decreased in operatively treated patients compared to conservatively treated patients (11.6% versus 24.0%; P < 0.001). Patients with antiplatelet pre-treatment had a significantly higher risk of death during the hospital stay after hematoma evacuation (odds ratio [OR]: 2.5; 95% confidence interval [CI]: 1.24–4.97; P = 0.010) compared to patients without antiplatelet pre-treatment treatment (OR: 0.9; 95% CI: 0.79–1.09; P = 0.376). In conclusion a higher rate of in-hospital mortality after pre-treatment with antiplatelet agents in combination with hematoma evacuation after spontaneous ICH was observed in the presented cohort.
