Purpose: The aim was to examine the predictors of improvement of quality of life after 2 years of coronary artery bypass grafting (CABG)., Methods: In all, 208 patients who underwent the elective CABG at the Institute for Cardiovascular Diseases Dedinje in Belgrade were contacted and examined 2 years after the surgery. All patients completed Nottingham Health Profile Questionnaire part one., Results: Two years after CABG, quality of life (QOL) in patients was significantly improved in all sections compared to preoperative period. Independent predictors of QOL improvement after 2 years of CABG were found to be serious angina under sections of physical mobility [p = 0.003, odds ratio (OR) = 1.76, 95% confidence interval (CI) 1.21-2.55], energy (p = 0.01, OR = 1.63, 95% CI: 1.11-2.38), sleep (p = 0.005, OR = 1.65, 95% CI: 1.16-2.35), pain (p <0.001, OR = 2.43, 95% CI: 1.57-3.77), absence of hereditary load in energy section (p = 0.002, OR = 0.35, 95% CI: 0.18-0.68), male sex in the sleep section (p = 0.03, OR = 0.43, 95% CI: 0.20-0.93), and absence of diabetes in pain section (p = 0.006, OR = 0.27, 95% CI: 0.10-0.68)., Conclusion: Predictors of improvement of QOL after 2 years of CABG are serious angina, absence of hereditary load, male sex, and absence of diabetes.

Purpose: The study evaluates the changes in quality of life (QOL) six months after coronary artery bypass grafting (CABG) related to the patients' age., Methods: The total of 243 consecutive patients completed the Nottingham Health Profile Questionnaire part 1 before and six months after CABG. Postoperative questionnaire was completed by 226 patients. Patients were divided into four examined groups (<50, 50-59, 60-69 and ≥70 years), according to their age., Results: Six months after CABG, the quality of life in different sections has been significantly improved in most patients.The analysis of the relation between the age and the changes in QOL of patients six months after CABG showed a significant correlation among the patients' age and the improvement of QOL in the sections of physical mobility (r = 0.18, p = 0.008), social isolation (r = 0.17, p = 0.01) and energy ( r = 0.21, p = 0.002). The most prominent improvement was found in older patients. The age was not an independent predictor of QOL deterioration after CABG., Conclusions: The most noticeable improvement of QOL six months after CABG was found in older patients. Age is not the independent predictor of deterioration of QOL after CABG.
