Abstract

The purpose of coronary artery bypass graft (CABG) is to increase survival, symptoms improvement and increasing the quality of life of patients, but in some literature there has been conflicting results regarding this issue. The aim of this study was to evaluate the quality of life of patients undergoing coronary artery bypass graft, considering METs (Metabolic equivalents) in exercise testing and functional class. Materials & Methods: In a sectional descriptive-analytic study, we evaluated 48 patients that were nominated for coronary artery bypass graft. For this purpose, indices including exertional chest pain, exertional shortening of breath, functional class and METs of patients were measured before and 6 months after the surgery and then were compared considering risk factors. Results: The mean age of patients were 6.16±63.47 y/o with 26 (54.2%) males. The mean function class of patients before surgery were 2.36±0.07 and after surgery was 1.72±0.08 (P<0.0001). The mean METs of patients were 6.41±0.49 before surgery and 8.04±1.27 after surgery (P<0.0001). Function class after surgery in males was 1.57±0.5 and 1.9±0.61 in females (P=0.044). Mean METs of patients in males were 8.4±1.23 and in females were 7.5±1.18. Function class of patients with diabetes was 2±0.59 and 1.5±0.5 in patients without diabetes (P=0.01). Mean METs of patients with diabetes was 7.38±1.19 and 8.43±1.16 in patients without diabetes (P=0.005). In all other condition, the differences were not statistically significant. Conclusion: CABG improves the function class and METs of patients especially in male and nondiabetic patients
