Randomized Controlled Trial Clinical Trial
Effects of acute treatment with pravastatin on cerebral vasospasm, autoregulation, and delayed ischemic deficits after aneurysmal subarachnoid hemorrhage: a phase II randomized placebo-controlled trial.
Statins may improve cerebral vasomotor reactivity through cholesterol-dependent and -independent mechanisms. A phase II randomized controlled trial was conducted to examine the hypothesis that acute pravastatin treatment could improve cerebrovascular autoregulation and reduce vasospasm-related complications after aneurysmal subarachnoid hemorrhage (SAH). ⋯ Acute treatment with pravastatin after aSAH is safe and ameliorates cerebral vasospasm, improves cerebral autoregulation, and reduces vasospasm-related DID. Unfavorable outcome at discharge was reduced primarily because of a reduction in overall mortality. This is the first demonstration of clinical benefits with immediate statin therapy for an acute cerebrovascular disorder.
