Several factors increase the risk of developing an aortic aneurysm or dissection, including environmental and genetic influences.
Environmental factors that increase the chance to develop an aortic aneurysm or dissection include:
- Uncontrolled hypertension (high blood pressure)
- Bicuspid aortic valve
- Weight lifting (see http://www.iradonline.org/articles/lifestyle_recs.html for recommendations regarding lifestyle and work)
- Trauma to the aorta (e.g. being in a car accident)
- Inflammatory diseases
Genetic factors also influence the risk to develop an aortic aneurysm or dissection. Thoracic aortic aneurysm and/or dissection (TAAD) can have three different types of genetic risk: familial TAAD, syndromic TAAD, or sporadic TAAD.
