Not to be confused with atherosclerosis Arteriosclerosis Not to be confused with atherosclerosis

Arteriosclerosis Also known as medial sclerosis or hardening of the arteries Not usually an occlusion problem

Calcium deposits in the tunica media and atheroma (if present) The calcium interrupts the elastic fibers of the media (traverses the media) Problem?

Acts like a clamp on fibers affecting the expansion of the vessels Contributes to hypertension

Calcium Deposit in Tunica Media ©http://images. google. com/imgres

Calcium Deposits in Coronary Arteries ©http://www. heartcheck. co

Is more often seen in older individuals Not nearly as common as atherosclerosis, but often a person has both
