Abstract

Background and purpose:? It is unclear whether pre-stroke beta-blockers use may influence stroke outcome. This study evaluates the independent effect of pre-stroke use of beta-blockers on ischaemic stroke severity and 3?months functional outcome. Methods:? Pre-stroke use of beta-blockers was investigated in 1375 ischaemic stroke patients who had been included in two placebo-controlled trials with lubeluzole. Stroke severity was assessed by either the National Institute of Health Stroke Scale (NIHSS) or the European Stroke Scale (ESS). A modified Rankin scale (mRS) score of >3 at 3?months was used as measure for the poor functional outcome. Results:? Two hundred and sixty four patients were on beta-blockers prior to stroke onset, and 105 patients continued treatment after their stroke. Pretreatment with beta-blockers did not influence baseline stroke severity. There was no difference in stroke severity between nonusers and those on either a selective beta(1) -blocker or a non-selective beta-blocker. The likelihood of a poor outcome at 3?months was not influenced by pre-stroke beta-blocker use or beta-blocker use before and continued after stroke onset. Conclusions:? Pre-stroke use of beta-blockers does not appear to influence stroke severity and functional outcome at 3?months.
