title: The role of statins in preventing stroke.
abstract: Epidemiological studies have not demonstrated a clear relationship between stroke risk and hypercholesterolemia. Clinical trials using statins have demonstrated a reduction in stroke, in particular, in patients with established coronary artery disease. The disparity between epidemiological and clinical studies suggests hypercholesterolemia is a true risk factor for stroke that evaded detection in epidemiological studies, or that statins possess other properties that render them useful in stroke prevention. These effects have been loosely termed "pleiotropic" in the lipid literature and revolve around putative effects of statins on endothelial function, inflammation, thrombosis, plaque stability, and immune regulation. Questions remain as to the mechanisms of benefit of statin therapy in stroke prevention, the role of statins in the primary prevention of stroke, and the role of statins in modulating the immune system in the brain.
