What has been a significant risk factor identified for the development of aortic aneurysms?

Age is recognized as a significant risk factor for the development of aortic aneurysms primarily because of the physiological changes that occur in the vascular system over time. As individuals age, their blood vessels undergo structural alterations, leading to increased susceptibility to conditions like aneurysm formation. The elastic fibers in the arterial walls can degrade, and the overall integrity of the vessel may diminish, making it more prone to dilatation.

Additionally, the prevalence of aortic aneurysms increases with age, particularly in populations over 65 years, as the cumulative exposure to risk factors such as hypertension and atherosclerosis also tends to be higher in older adults. Understanding the aging process in relation to vascular health provides critical insight for monitoring and managing the risk of aortic aneurysms in the aging population.
