What is the common underlying disorder linked to aortic aneurysm?

Aortic aneurysms are most commonly associated with atherosclerosis, which is the buildup of plaques in the arterial walls. This condition leads to weakening and dilation of the vessel wall, which can eventually result in an aneurysm. Atherosclerosis contributes not only to aneurysm formation but also increases the risk of complications associated with aneurysms, such as rupture.

While other conditions like hypertension, hyperlipidemia, and diabetes mellitus can influence cardiovascular health and may contribute to an increased risk of aortic issues, atherosclerosis is recognized as the primary underlying disorder that directly impacts the structural integrity of the aorta, making it the most relevant factor in the context of aortic aneurysms.
