Abstract Background Impaired quality of life (QOL) is common in coronary heart disease and is the major indications for coronary artery bypass graft (CABG) operations. This study aims to compare the QOL of patients with coronary heart disease before and after CABG surgery. Results A translated Arabic version of the Mac-New health-related QOL questionnaire was used to evaluate QOL improvement in 446 patients who benefited from elective CABG at Nasser Institute for Research and Treatment. There was a statistically significant improvement in physical, emotional, social, and global domains of QOL, as evaluated 3 and 6 months after surgery. Follow-up was 90.4% complete. At 3 months, multiple linear regression has shown that male patients (β = 0.48, p ≤ 0.001) and rural residence (β = 0.39, p ≤ 0.001) were significant independent predictors of improvement in physical QOL domain. While hypercholesterolemia (β = −0.20, −0.49, −0.37, −0.46, p ≤ 0.001), hypertension (β = −0.29, −0.39, p ≤ 0.001, β = −0.35, −β = 0.35, p = 0.001), and smoking (β = −0.79, p ≤ 0.001, β = −0.33, p = 0.04, β = −0.69, p ≤ 0.001, β = −0.47, p = 0.005) were significant predictors of worsening in physical, emotional, social, and global domains, respectively. At 6 months, low preoperative ejection fraction (EF) ≤ 40% was the strongest predictor of improvement (β = 0.54, 0.49, 0.44, and 0.52, p ≤ 0.001) in physical, emotional, social, and global domains of QOL, respectively. But, peripheral vascular disease (PVD) (β = −0.53, p = 0.05, β = −0.81, p = 0.005, β = −0.62, p = 0.03, β = −0.76, p = 0.008) and smoking (β = −0.53, p = 0.001, β = −0.42, p = 0.01, β = −0.42, p = 0.01, β = −0.41, p = 0.02) were significant predictors of worsening in physical, emotional, social, and global domains of QOL, respectively. Conclusions CABG surgery improved in all domains of QOL. Further studies are required to evaluate changes in QOL at longer period intervals.
