What is the outcome of the Asymptomatic Carotid Atherosclerosis Study (ACAS)?
The primary outcome of the Asymptomatic Carotid Atherosclerosis Study (ACAS) was the composite of any stroke or death occurring in the perioperative period and ipsilateral cerebral infarction thereafter. During follow-up after 34 centers randomized 1662 patients, the Data and Safety Monitoring Committee called a halt to the trial because of a clear benefit in favor of CEA.
