[Quality of life of patients after coronary bypass surgery: effect of age and personality type D].

Aim: To study effect of age and presence of personality type D on quality of life (QL) of patients in one year after coronary bypass surgery (CBS).

Material And Methods: Assessment of QL before and after surgery was carried out in 408 patients. Two groups were formed: patients younger than 60 years (n=233) and older than 60 years (n=175). Quality of life and presence of personality type D was assessed by questionnaires SF-36 and DS-14, respectively.

Results: In a year after CBS improvement of physical and psychological components of QL (p<0.05) was noted in both groups. Personality type D was more frequent among patients older than 60 years (p<0.01). Patients with personality type D had worse parameters of irrespective of age (p<0.01). Personality type D correlated directly with age QL (p=0.003) and inversely with parameters of QL (p<0.01). Presence of personality type D was an independent predictor of low level of physical (together with index of atherogenecity prior to surgery) and psychological components of QL at multiple logistic regression analysis.

Conclusion: Assessment of personality traits of patients before CBS can be helpful for targeted measures aimed at improvement of QL what is especially important for older age groups.
