  Purpose

The study aims to evaluate neuropsychological disorders in CABG patients. Measurements are performed 1 day before, 6 days, 6 months and 3-5 years after the surgery. The relation with cerebrovascular reactivity and embolic load (measured by transcranial Doppler Ultrasonography) is evaluated. Two surgery techniques (on- and off-pump CABG) are compared.
