In the United States, 90% of patients with asymptomatic carotid artery stenosis are treated with carotid artery intervention. In Denmark, the rate is 0%. The study assesses the risk of stroke in those patients with stenosis and then occlusion of the common carotid artery. This retrospective study analyzed data from two prevention clinics in Canada.
