Delirium is a common, morbid, and costly syndrome that occurs frequently after surgery for atherosclerosis. We hypothesized that vascular risk factors and mildly impaired cognitive performance would independently predispose nondemented patients to develop delirium after noncardiac surgery. ⋯ Vascular risk and mildly impaired cognitive performance independently predispose patients to delirium after noncardiac surgery. These factors will help to identify high-risk patients for delirium and to design and target future intervention strategies.
