Is aortic aneurysm inherited?

Depends: An aortic aneurysm can be the result of inherited conditions like marfan's syndrome. Conversley, aortic aneurysms may appear 'de novo' in those without a family history and only clinical risk factors such as atherosclerosis and hypertension. Since the relationship between genetics and environment is complex, if there is a family history one should always be extra vigilant and monitor.

Not really: Some increased incidence in some families. Also marfan, , ehrlos danlos and some congenital. The dominant number of AAA seem related to age, atherosclerosis. But we check family members for this common condition.
