Abstract/OtherAbstract:
BACKGROUND AND PURPOSE: Previous antiplatelet therapy (APT) in cardiovascular prevention is common in patients with first-ever stroke. We aimed to evaluate the prognostic value of APT on early outcome in stroke patients. METHODS: All first-ever strokes from 1985 to 2011 were identified from the population-based Stroke Registry of Dijon, France. Demographic features, risk factors, prestroke treatments and clinical information were recorded. Multivariate analyses were performed to evaluate the associations between pre-admission APT and both severe handicap at discharge, and mortality at 1 month and 1 year. RESULTS: Among the 4275 patients, 870 (20.4%) were previously treated with APT. Severe handicap at discharge was noted in 233 (26.8%) APT users and in 974 (28.7%) non-users. Prestroke APT use was associated with lower odds of severe handicap at discharge [adjusted odds ratio (OR): 0.79; 95% confidence interval (CI): 063-1.00; P = 0.046], non-significant better survival at 1 month [adjusted hazard ratio (HR): 0.87; 95% CI: 0.70-1.09; P = 0.222] and no effect on 1-year mortality (HR: 0.94; 95% CI 0.80-1.10; P = 0.429). In stratum-specific analyses, APT was associated with a lower risk of 1-month mortality in patients with cardioembolic ischaemic stroke (HR: 0.65; 95% CI: 0.43-0.98; P = 0.040). CONCLUSIONS: APT before stroke was associated with less severe handicap at discharge, with no significant protective effect for mortality at 1 month except in patients with cardioembolic stroke. No protective effect of APT was observed for mortality at 1 year. Further studies are needed to understand the mechanisms underlying the distinct effects of prior APT observed across the ischaemic stroke subtypes.
