動脈硬化: Arteriosclerosis 

動脈粥狀硬化: Atherosclerosis

Arteriosclerosis is characterized by intimal fibrosis of large elastic arteries,
atherosclerosis is characterized by intimal and medial lipid deposits in elastic and muscular arteries, and arterial medial calcification has characteristic mineralization of the walls of elastic and muscular arteries.

Arteriosclerosis is an age-related disease that occurs frequently in many animal species but rarely causes clinical signs. 

Atherosclerosis, the vascular disease of greatest importance in human beings, occurs only infrequently in animals and rarely leads to clinical disease such as infarction of the heart or brain.
