Abstract:

OBJECTIVE

To study the impact of long-term postoperative cognitive dysfunction (POCD) on the quality of life in 1 year after elective coronary artery bypass grafting (CABG).

MATERIAL AND METHODS

There were 100 male patients who were examined within 3—5 days before CABG and a year later. Cognitive status was assessed using the “Status PF” psychophysiological complex software. SF-36 questionnaire was used to assess the quality of life. All patients were divided into groups with (n=57) and without long-term POCD (n=43). Statistical analysis was performed using Statistica 10.0 software. Spearman’s correlation coefficient and linear multiple regression were used to analyze relationships between the quality of life and cognitive parameters.

RESULTS

Patients without long-term POCD were characterized by better general health (GH), physical functioning (PF), role functioning (RP), bodily pain (BP), vitality (VT) and mental health (MH) in 1 year after CABG (p<0.05). POCD patients showed improvements only in PF, RP and BP items. Integral memory and attention parameters positively correlated with PF scores (r=0.22, p=0.03 and r=0.32, p=0.002, respectively). VT scores positively correlated with attention and neurodynamics (r=0.21, p=0.04 and r=0.22, p=0.03, respectively). Integral short-term memory and attention indicators were the main predictors explaining 15% variance of PF scores according to regression model.

CONCLUSION

No long-term POCD was associated with improved physical and mental components of the quality of life in 1 year after CABG. Patients with postoperative cognitive deficit showed an improvement only in physical component. A better cognitive status is associated with higher quality of life suggesting an ability to physical activity and vitality.
