What is the between atherosclerosis and arteriosclerosis? Can a person have one but not the other ?

What are other forms of arteriosclerosis?

Arteriosclerosis is hardening of the walls of the arteries, the blood vessels carrying oxygenated blood to the organs. It usually does not compromise the lumen of the vessel, but makes it stiff and may cause elevation of the bood pressure recordings.

Atherosclerosis is deposition of fat like material in the inner lining of the arteries. This will cause narrowing of the vessel and obstruct flow if severe. The deposits known as plaques can also rupture and expose raw areas leading to formation of blood clots. These clots may totally obstruct the flow. If this occurs in an artery of the heart, it may lead to a heart attack. If it occurs in an artery of the brain, it may lead to a stroke.

Arteriosclerosis need not necessarily be associated with significant atherosclerosis and vice versa.

Yes you can have atherosclerosis, but not arteriosclerosis. atherosclerosis is just the inflammation of the walls, but arteriosclerosis adds another problem, which is the hardening of the walls by calcium deposits, which are created naturally by the body in an attempt to strengthen the vessel.
