Abdominal aortic aneurysm (AAA) is a common and potentially dangerous vascular disease with many risk factors related to its occurrence and development.This review collects the results from recent studies of different comorbidities including hypertension,diabetes,and hyperlipidemia and summarizes their connections with AAA development and its underlying mechanisms.We believe that hypertension,diabetes,and hyperlipidemia can affect AAA occurrence and development,but more studies are needed to further explore the mechanisms.
