title: [Cholesterol and stroke risk: a role for statins?].
abstract: Atherosclerosis is the most common cause of vascular diseases, but the relevance of cholesterol has only been definitely associated with coronary artery disease and peripheral vascular disease. In comparison, the role of cholesterol in stroke is, while a tempting assumption, subject to controversy in the literature. The crucial question--is cholesterol a risk factor for stroke?--remains open. Recent trials with statin drugs, such as 4 S, CARE, LIPID and WOSCOP, have created a new wave of enthusiasm by showing decreased risk of stroke in the statin-treated patients. However, these trials are most often designed for patients with a known history of coronary artery disease. In contrast, studies investigating the impact of statins in the secondary prevention of stroke are still lacking. Moreover, the beneficial effects of statins on clinical events may involve non-cholesterol mechanisms. In regard to stroke prevention, there is no absolute evidence to recommend the use of statin drug therapy.
