INTRODUCTION: Although there is sufficient evidence that HMG CoA Reductase Inhibitors reduce stroke recurrence in patients with or ischemic heart disease, it remains unclear whether they also improve outcomes given before or after stroke onset and whether such an effect is more robust with pre-stroke or post-stroke use of statins.

MATERIALS AND METHODS: We carried out a retrospective analysis of a large University Health Consortium Database. Patients with statin use before or after stroke onset were included in the analysis. Twenty patients discontinued statins after stroke onset. The outcome measures were discharge home or long-term care facility and/or death within 45 days.

RESULTS: Patients with prior statin use were more likely to be discharged home (1.67, CI 1.12-2.49), as were post stroke statin patients who had a more robust effect OR 2.63, CI 1.61-4.53).

CONCLUSIONS: Patients started on statins after stroke were more likely to be discharged home versus patients already on statins before stroke onset. However, both groups were also more likely to be discharged home than those patients not on statins.
