Changes in Cerebrovascular Reactivity During Cognitive Activation After Cardiopulmonary Bypass: Relation With Intraoperative Embolic Load and Postoperative Neuropsychological Dysfunctions

Changes in Cerebrovascular Reactivity During Cognitive Activation After Cardiopulmonary Bypass: Relation With Intraoperative Embolic Load and Postoperative Neuropsychological Dysfunctions

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.

Inclusion Criteria:

• CABG-patients (not urgent)
• < 70 years old
• Righthanded

Exclusion Criteria:

• Neurological or psychiatric disease
• Psychoactive medication
• Valve operation
