a chronic disease characterized by abnormal thickening and hardening of the walls of the arteries, esp. of the intima, occurring mostly in old age. Subtypes are distinguished, such as arteriolosclerosis and atherosclerosis.
Literally the hardening and thickening of the arteries. This condition, divided into three distinct variants, can occur due to build up of fat deposits (plaque) on the inner walls of arteries (atherosclerosis), calcification of the wall of the arteries (Monckeberg's medial calcific sclerosis), or thickening of the muscular wall of small arteries and arterioles (arteriolosclerosis).
A group of diseases in which the walls of the arteries get thick and hard. In one type of arteriosclerosis, fat builds up inside the walls and slows the blood flow. These diseases often occur in people who have had diabetes for a long time. See also: Atherosclerosis.
