Final answer:
Age, hypertension, smoking, and family history are major risk factors for an aortic aneurysm and dissection, with hypertension being a key contributor. Lifestyle changes can significantly reduce these risks.
Step-by-step explanation:
The major risk factors for an aortic aneurysm and dissection include age, hypertension, smoking, and a family history of cardiovascular diseases. Among these, hypertension (high blood pressure) is particularly noteworthy, as it can contribute to the weakening of the artery wall, increasing the risk of both an aneurysm and a dissection. With each decade of life, the risk of cardiovascular diseases notably triples. Other modifiable lifestyle factors such as smoking, obesity, and lack of physical activity also play a significant role in the development of these conditions.
Smoking is one of the well-documented risk factors and contributes to fatty streaks in vessels, which can progress into more significant cardiovascular issues. Maintaining a healthy lifestyle by quitting smoking, controlling hypertension, engaging in regular physical activity, and managing other cardiovascular risk factors can significantly lower the risk of developing an aortic aneurysm or dissection.
