Previous antiplatelet treatment did not significantly affect the rate of poor functional outcome at hospital discharge in patients with cerebral hemorrhage (52.1% vs 59.7%; p=n.s.).

Does prior antiplatelet treatment worsen clinical outcomes at hospital discharge in patients with primary intraparenchymal hemorrhage?
Prior antiplatelet treatment does not appear to worsen functional outcome or in-hospital mortality in patients presenting with primary intraparenchymal hemorrhage.
Absolute Event Rate: 52.1% vs 59.7%
p-value: p=n.s.
BACKGROUND: Antiplatelet treatment remains the first choice for primary and secondary prevention of vascular diseases; even so, expected benefits may be offset by risk of bleeding, particularly cerebral hemorrhage. The aim of this study was to assess the influence of antiplatelet treatment on clinical outcome at hospital discharge. MATERIALS AND METHODS: Consecutive patients with first-ever stroke due to a primary intraparenchymal hemorrhage were prospectively identified over a 4-year period (2000-2003). Data on hemorrhage location, vascular risk factors, and antiplatelet and anticoagulant treatment were collected. At discharge, outcome was measured using the modified Rankin Scale (disabling stroke > or =3). Patients treated with anticoagulant therapy were excluded from the study. RESULTS: Of 457 consecutive patients with cerebral hemorrhage, 94 (20.5%) had been taking antiplatelet agents. The treated patients (mean age for antiplatelet group 78.9 +/- 9.0 years) were older than the nontreated patients (73.8 +/- 9.4, p = 0.02). In-hospital mortality was 23.4 and 23.1% (p = n.s.) for patients who had been taking antiplatelet agents or no treatment. Poor outcome at discharge was found in 52.1 and 59.7% (p = n.s.), respectively. Univariate analysis showed that age and coma at admission were predictors of disability at discharge, but antiplatelet treatment was not. Additionally, age and coma were shown to be determinants of disability at discharge after multivariate analysis: OR 1.03 per year (95% CI: 1.018-1.049), p < 0.001 and OR 1.68 (95% CI: 1.138-2.503), p = 0.009, respectively. CONCLUSIONS: Hemorrhagic stroke continues to be responsible for a high percentage of disability and death. Furthermore, it was seen here that functional outcome was independent of previous antiplatelet treatment.
Caso et al. (2007) conducted a cohort in Cerebral hemorrhage (n=457). Antiplatelet treatment vs. No antiplatelet treatment was evaluated on Poor outcome at discharge (modified Rankin Scale ≥3) (p=n.s.). Previous antiplatelet treatment did not significantly affect the rate of poor functional outcome at hospital discharge in patients with cerebral hemorrhage (52.1% vs 59.7%; p=n.s.).
