Predictors of worsening of patients' quality of life six months after coronary artery bypass surgery.
BACKGROUND
The possibility to predict the change in (the) quality of life after coronary artery bypass surgery (CABG) being unclear, the aim was to evaluate the change of quality of life and predictors of worsening of quality of life in patients six months after CABG.


METHODS
We studied 208 consecutive patients, who underwent elective CABG. The Nottingham Health Profile Questionnaire part 1 was used as the model for quality of life determination. The questionnaire contains 38 subjective statements divided into six sections: physical mobility, social isolation, emotional reaction, energy, pain, and sleep. We distributed the questionnaire to all patients before CABG and six months after CABG. One hundred ninety-two patients filled in the postoperative questionnaire.


RESULTS
The comparison between mean preoperative and postoperative scores showed an improvement in all sections of quality of life (p < 0.001). New York Heart Association functional class was significantly improved after CABG (2.23 +/- 0.65 vs. 1.58 +/- 0.59, p<0.001). Independent predictors of patients worsened by CABG were as follows: female gender in the pain section (p = 0.002; OR = 4.27; CI 1.74-10.47), diabetes mellitus in the physical mobility section (p = 0.003; OR = 8.09; CI 2.04-32.09), low ejection fraction in the physical mobility (p = 0.047; OR = 0.73; CI 0.56-0.95) and emotional reaction (p = 0.03; OR = 0.86; CI 0.60-0.93) sections, and postoperative complications in the social isolation (p = 0.002; OR = 4.63; CI 1.79-11.99), sleep (p = 0.03; OR = 2.71; CI 1.12-6.51), and pain (p = 0.005; OR = 3.39; CI 1.45-7.97) sections.


CONCLUSIONS
The predictive factors for quality of life worsening six months after CABG are female gender, diabetes mellitus, low ejection fraction, and the presence of postoperative complications.
