TYPE D PERSONALITY AND QUALITY OF LIFE ONE YEAR AFTER CORONARY ARTERY BYPASS GRAFT SURGERY

Abstract

Aim. To investigate the effects of Type D personality traits on psychological status (PS) and quality of life (QoL) in patients with coronary heart disease one year after coronary artery bypass graft surgery (CABG).Material and methods. PS was assessed at baseline and after CABG in 408 patients, who were divided into two groups: with Type D personality traits (n=93; Group 1) and without these traits (n=315; Group 2). The Spielberger-Khanin, depression, SF-36, and DS-14 scales were used for PS assessment. Results. One year after CABG, fewer patients reported high levels of anxiety, and there was an improvement in physical functioning and physical status QoL domains (p<0,05). The percentage of patients with Type D personality traits did not change over time, suggesting that this chronic psychological risk factor is relatively stable. Type D personality traits negatively affected the levels of anxiety, depression, and QoL one year after CABG. According to the results of multivariate logistic regression analyses, type D personality and elevated levels of trait anxiety of psychological and physical QoL parameters.Conclusion. The tendency towards psychological distress, a stable personality trait observed both before and one year after CABG, was associated with reduced psychological and physical QoL parameters. The pre-CABG assessment of personality traits could optimise the complex management strategy and improve QoL.
