Asymptomatic carotid artery stenosis and cognitive outcomes after coronary artery bypass grafting.

Objective: Cognitive decline has a negative impact on early postoperative morbidity and affects subjective quality of life. The role of asymptomatic cerebrovascular disease in developing postoperative neurocognitive damage remains controversial. The aim of our study was to evaluate the impact of asymptomatic carotid artery stenosis on postoperative cognitive decline.

Incidence and risk factors for early postoperative cognitive decline after coronary artery bypass grafting.

BACKGROUND. The aim of our study was to evaluate the incidence of early postoperative cognitive decline (POCD) and determine perioperative risk factors as well as the impact of asymptomatic cerebral vascular lesion on the development of neurocognitive complications. MATERIALS AND METHODS.
