This retrospective cohort study evaluates cardiovascular events directly related to treated coronary arteries in patients with stable multivessel coronary artery disease. Outcomes in patients undergoing coronary artery bypass grafting or percutaneous coronary intervention will be compared with those receiving optimized medical therapy alone. This study aims to improve understanding of how different treatment strategies impact long-term vessel-related outcomes in patients with stable multivessel coronary artery disease.
Previous studies evaluating coronary revascularization strategies have relied on broad composite endpoints, which may include events unrelated to the treated vessel. This study focuses on vessel-related outcomes, specifically non-fatal myocardial infarction and cardiac death attributable to the treated coronary artery. Patients were selected from the MASS (Medicine, Angioplasty, or Surgery Study) database at a single tertiary center. By analyzing vessel-specific events, this study aims to provide a more accurate assessment of the long-term impact of different treatment strategies in stable multivessel coronary artery disease.
