The majority of studies on neuropsychological complications after cardiac surgery used the raw variation of selective tests scores to define the occurrence of cognitive decline. We prospectively estimated the frequency of cognitive impairment after cardiac surgery, with a particular emphasis on persistent and clinically relevant cognitive decline. Possible baseline and operative predictors were also evaluated. ⋯ A considerable proportion of cardiac surgery patients may undergo clinically relevant cognitive impairment. The knowledge of variables influencing cognitive outcome is essential for the adoption of preventive measures.
