Atorvastatin decreases computed tomography and S100-assessed brain ischemia after subarachnoid aneurysmal hemorrhage

Abstract

Atorvastatin reduces the incidence, the severity and the ischemic consequences of vasospasm as assessed on computed tomography. In high-grade World Federation of Neurological Surgeons patients, atorvastatin decreases serum levels of S100B, a biomarker of brain ischemia. Despite these positive effects on biomarkers, no improvement of outcome was seen in the overall population, although there was a tendency for a better clinical outcome in high-grade patients.
