Abstract

The problem of cognitive dysfunction in patients after cardiac surgery is intensively studied at present. In the present study decrease of verbal memory was common after both coronary (CABG) and open heart (OH) operations. In addition, patients OH showed postoperative decrease of non-verbal memory and visual-constructional ability. Patients after CABG demonstrated psychomotor slowing postoperatively. Patients with enlarged left heart chambers regularly demonstrate proneness to hypercoagulation, hypoperfusion and microemboli at cerebral circulation, which lead to development of multiple ischemic lesions and neurotrophic alterations, which underlie the cognitive dysfunction. In the present study the association between heart chambers enlargement and cognitive dysfunction after cardiac surgery is showed.
