Features of psychological status in patients after coronary artery bypass grafting with different duration of outpatient rehabilitation stage

Objective. To analyze the characteristics of the psychological status in patients after coronary artery bypass graft (CABG) with different recovery periods. Materials and methods. The study included 100 men (53.2±5.9 years) who had undergone CABG. Retrospectively, 2 groups were identified: group 1 (n=58) – patients returned to work 4 months after CABG; group 2 (n=42) – patients required rehabilitation for more than 4 months. The control group consisted of healthy volunteers (n=50). All patients were assessed for anxiety levels using the Spielberger–Hanin Anxiety Scale 1 and 4 months after CABG. Results. Patients after CABG have higher levels of personal and situational anxiety compared to the control group (p=0.001). Initially, the levels of situational and personal anxiety in patients of the studied groups were comparable (p=0.936, p=0.109, respectively). By the 4th month, the level of situational anxiety in group 1 decreased (p=0.001), while in group 2 the indicator remained unchanged (p=0.764). Regression analysis established that 82% of the variability of situational anxiety in group 2 was determined by the combined effect of age (β=0.552; p=0.001), hypertension (β=3.341; p=0.023), previous infarction (β=7.291; p=0.001), and the number of bypasses (β=4.259; p=0.001). Conclusions. There is a need to take into account the special role of psychological correction in the system of complex rehabilitation of patients with coronary heart disease who have undergone CABG.
