A Comparison of Two Multi-Tasking Approaches to Cognitive Training in Cardiac Surgery Patients.

Background: The multi-tasking approach may be promising for cognitive rehabilitation in cardiac surgery patients due to a significant effect on attentional and executive functions. This study aimed to compare the neuropsychological changes in patients who have undergone two variants of multi-tasking training and a control group in the early postoperative period of coronary artery bypass grafting (CABG).

Methods: One hundred and ten CABG patients were divided into three groups: cognitive training (CT) I (a postural balance task with mental arithmetic, verbal fluency, and divergent tasks) ( = 30), CT II (a simple visual-motor reaction with mental arithmetic, verbal fluency, and divergent tasks) ( = 40), and control ( = 40).

Cognitive functions and patterns of brain activity in patients after simultaneous coronary and carotid artery revascularization.

Background: On-pump coronary artery bypass grafting (CABG) is associated with a high risk of neurological complications in patients with severe carotid stenosis. Moreover, early postoperative cognitive dysfunction (POCD) incidence remains high in patients undergoing simultaneous coronary and carotid surgery. Recent studies have shown that even moderate carotid stenosis (≥50%) is associated with postoperative cognitive decline after CABG.
