OBJECTIVES This study sought to determine whether post-operative neurocognitive dysfunction (POCD) occurs after ablation for atrial fibrillation (AF). BACKGROUND Ablation for AF is a highly effective strategy; however, the risk of transient ischemic attack and stroke is approximately 0.5% to 1%. In addition, magnetic resonance imaging studies report a 7%(More)
BACKGROUND An accurate assessment of the prevalence of cognitive impairment in patients scheduled for coronary artery bypass graft (CABG) surgery is necessary if valid assumptions regarding cognitive change are to be made. Such an assessment requires the use of a healthy control group free of cardiovascular disease. METHODS In a retrospective(More)
BACKGROUND The relationship of aortic atheroma to postoperative cognitive dysfunction (POCD), a common complication of coronary artery bypass graft surgery, has not been resolved. We undertook assessment of aortic atheroma using intraoperative ultrasonography and related the degree of aortic atheroma to POCD. METHODS Aortic atheroma was assessed using(More)
Cognitive deterioration can reliably be measured after procedures requiring anesthesia and surgery. Cardiac surgery has had the spotlight because of the high reported incidence of postoperative cognitive dysfunction in early studies, but such effects occur after other surgical procedures as well. "Early" postoperative cognitive dysfunction should be(More)
BACKGROUND Decreased cognitive function associated with coronary artery bypass graft surgery is common. These deficits may be similar to the cognitive dysfunction seen in the spectrum of mild cognitive impairment to Alzheimer's disease, which are believed to result from the accumulation of amyloid beta (Abeta) peptide in the brain. We measured cognition(More)
BACKGROUND This study investigated the prevalence of cognitive impairment in elderly noncardiac surgery patients and any association between preoperative cognitive impairment and postoperative cognitive dysfunction (POCD). Additionally, the incidence of cognitive decline at 12 months after surgery was identified. METHODS Three hundred patients for hip(More)
BACKGROUND Postoperative cognitive dysfunction (POCD) has been documented after cardiac and noncardiac surgery. The type of surgery and anesthetic has been assumed to be associated with the incidence but there are few prospective data comparing the incidence after different procedures. In this study, we sought to determine the association of the type of(More)
BACKGROUND Postoperative cognitive decline is a common complication after coronary artery bypass graft (CABG) surgery. Postoperative cognitive decline is defined on the basis of change in cognitive function detected with repeated assessments using neuropsychological tests. Therefore improvement in neuropsychological testing instruments may increase our(More)
