Health-Related Quality of Life After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Graft Among Iranian Patients

Background: Choosing unsuitable therapeutic methods affects patients’ quality of life. The present study aimed to compare quality of life between patients treated with coronary artery bypass graft surgery (CABG) and those treated with percutaneous coronary intervention (PCI). Method: This cohort study sought to assess quality of life in 290 patients with 3-vessel or left main coronary artery disease, who were referred to Ekbatan Hospital, Hamedan, Iran, to undergo either CABG or PCI. Health-related quality of life was investigated at baseline and subsequently at 6 and 12 months postprocedurally with the 36-Item Short-Form Health Survey (SF-36). The patients’ quality of life was evaluated based on a scoring system from 0 to 100, with higher scores representing a better health status. The primary outcomes were the physical component summary and mental component summary scores from the SF-36. Results: The study results revealed a significant difference between the 2 groups regarding physical functioning, role-physical, bodily pain, general health, vitality, social functioning, roleemotional, and mental health at baseline as well as at 6 and 12 months after the procedures (P < 0.001). Moreover, a significant relationship was observed between the type of procedure and desired quality of life (P < 0.05), which was more significant for PCI. However, no significant relationship was found between quality of life and diabetes, hyperlipidemia, highdensity lipoprotein level, cigarette smoking, and the body mass index (P > 0.05). Conclusions: Our investigation of quality of life in the CABG and PCI groups using the SF-36 questionnaire revealed that quality of life was better in the PCI group
