BACKGROUND Cognitive impairment after coronary artery bypass grafting (CABG) is well recognized, but previous investigations have been limited by lack of an appropriate control group. We compared changes in cognitive performance at 3 and 12 months after CABG with those in a control group of patients with comparable risk factors for coronary artery disease(More)
BACKGROUND Coronary artery bypass grafting has been associated with both early and late postoperative cognitive decline, but interpretation of previous studies has been limited by lack of appropriate control groups. We compared changes in cognitive performance from baseline to 3 years in patients undergoing coronary artery bypass grafting with those of a(More)
OBJECTIVE To determine the long-term (preoperative to 5 years postoperative) and late (1-5 years postoperative) changes in cognitive test performance in patients after coronary artery bypass grafting. SETTING The departments of surgery and neurology at The Johns Hopkins University School of Medicine, Baltimore, Md. PATIENTS A group of 102 patients who(More)
The purpose of this study was to determine whether depression 1 month after coronary artery bypass surgery would be associated with greater cardiac morbidity in patients 5 years later. The cardiac symptom most affected by depression was the recurrence of angina. Factors associated with a return of angina at 5 years were depression measured preoperatively,(More)
OBJECTIVE Delirium is common after cardiac surgery, although under-recognized, and its long-term consequences are likely underestimated. The primary goal of this study was to determine whether patients with delirium after coronary artery bypass graft (CABG) surgery have higher long-term out-of-hospital mortality when compared with CABG patients without(More)
OBJECTIVE The choice of coronary artery bypass grafting (CABG) as an intervention for coronary artery disease has been clouded by concerns about postoperative cognitive decline. Long-term cognitive decline after CABG has been reported, but without appropriate control subjects, it is not known whether this decline is specific to CABG or related to other(More)
BACKGROUND Stroke remains a devastating complication of cardiac surgery, but stroke prevention remains elusive. Evaluation of early and long-term clinical outcomes and brain-imaging findings may provide insight into stroke prognosis, etiology, and prevention. METHODS Five thousand nine hundred seventy-one cardiac surgery patients were prospectively(More)
BACKGROUND AND PURPOSE Watershed strokes are more prevalent after cardiac surgery than in other stroke populations, but their mechanism in this setting is not understood. We investigated the role of intraoperative blood pressure in the development of watershed strokes and used MRI to evaluate diagnosis and outcomes associated with this stroke subtype. (More)
BACKGROUND AND PURPOSE Coronary artery bypass grafting (CABG) is a frequently performed surgical procedure that can be associated with neurological complications. Some studies have demonstrated that new focal brain lesions, detected by MRI, can develop after CABG. Furthermore, it has been suggested that the presence of such new lesions is associated with a(More)
BACKGROUND It is widely assumed that decline in cognition after coronary artery bypass grafting (CABG) is related to use of the cardiopulmonary bypass pump. Because most studies have not included comparable control groups, it remains unclear whether postoperative cognitive changes are specific to cardiopulmonary bypass, general aspects of surgery, or(More)
