Question

The most common risk factor for aortic dissection in individuals older than 60 years is:

a) Hypertension
b) Smoking
c) Hypercholesterolemia
d) Atherosclerosis

Answer 1

Hypertension is the most common risk factor for aortic dissection in individuals older than 60 years, as it leads to arteriosclerosis and can contribute to atherosclerosis.

Step-by-step explanation:

The most common risk factor for aortic dissection in individuals older than 60 years is hypertension. This condition is associated with a generalized loss of compliance and hardening of the arteries, known as arteriosclerosis, and can also specifically refer to the buildup of plaque within the arterial walls, called atherosclerosis. Other factors for cardiovascular disease progression include advanced age, genetics, smoking, hypercholesterolemia, obesity, diabetes, and lifestyle behaviors; however, hypertension is considered a leading risk factor for aortic dissection in older individuals.
