Abstract Aortic aneurysm is an increasingly important public health problem with high morbidity and mortality. It is associated with coronary artery disease (CAD), which is a comorbidity of high incidence that is reported to worsen perioperative complications and long-term clinical outcomes in patients with an aortic aneurysm. Patients with significant coronary artery stenosis may require coronary revascularization and/or optimal medical therapy in the perioperative period of aneurysm surgery. However, the prognostic impact of non-significant coronary artery stenosis not indicated for coronary revascularization on clinical outcomes of patients with aortic aneurysms remains unclear. We performed coronary angiography on 239 consecutive patients with thoracic and abdominal aortic aneurysms before endovascular aortic repair or surgical repair. The patients were divided into the following 3 groups according to the severity of stenosis of major coronary arteries: non-CAD group (with
