Background: A coronary artery bypass graft (CABG) is a significant operation in which healthy blood vessel tissue is used to bypass a patient's blocked coronary arteries. Objective: Review of literature aboutclinical outcomes of coronary artery bypass graft in chronic obstructive pulmonary disease. Methods: We searched PubMed, Google Scholar, and Science Direct for relevant articles on Coronary Artery Bypass Graft and Chronic Obstructive Pulmonary Disease. However, only the most recent or thorough study was taken into account between January 2008 and January 2023. The authors also evaluated the value of resources culled from other works in the same genre. Therefore, documents written in languages other than English have been ignored due to a lack of translation funds. Unpublished works, oral presentations, conference abstracts, and dissertations were generally agreed upon not to qualify as scientific research. Conclusion: Bypass surgery improves cardiac function, viability, and anginal symptoms by re-establishing blood supply to the ischemic myocardium. Although coronary artery bypass grafting (CABG) surgery remains the most common major surgical procedure, its popularity has been declining in recent years due to the rise in the use of non-invasive procedures including medicinal therapy and percutaneous coronary intervention (PCI). Remodeled airways, fueled by inflammation and angiogenesis, can have unfavourable consequences for organs outside of the lungs in people with chronic obstructive pulmonary disease.
