Predictors of improved quality of life after coronary artery bypass surgery (CABG) are still incompletely known. To determine the predictors of improving the quality of life six months after coronary artery bypass surgery. 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. 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. The mean age of patients was 58,8 ± 8,2 years, 82% were males. The comparison between mean preoperative and postoperative scores showed that improvement was found in 53.7% of patients, worsening in 12.5%, quality of life before and after the intervention was normal in 26.7%, and no changes in quality of life was at 7.08%. Independent predictors of patients improvement by CABG were as follows: absence of previous myocardial infarction in the physical mobility section (p=0.03; OR=0.59; CI 0.40-0.92), higher CCS angina class in the physical mobility (p=0.006; OR=2.34; CI 1.46-3.32), energy (p=0.02; OR=1.70; CI 1.29-2.64) and pain sections (p<0.001; OR=4,64; CI 2.27-7.31), mail gender in the pain section (p=0.03; OR=0.45; CI 0.26-0.62) and younger age in the pain section (p=0.01; OR=0.69; CI 0.41-0.85). The predictive factors for quality of life improvement six months after CABG are higher CCS angina class, absence of previous myocardial infarction, mail gender and younger age.
