Atherosclerosis:

A gradual process that occurs when cholesterol collects under the inner lining of artery walls due to damage from uncontrolled high blood pressure, smoking, diabetes, or high blood cholesterol. The deposits (cholesterol plaques) eventually result in fibrosis and calcification, which may narrow or block the artery and hinder blood flow. Also called "hardening of the arteries," the disease can produce angina pectoris, heart attack, or stroke. 

Hardening of the arteries. Fatty deposits called plaques form on the inner lining of the lumen. The narrowed passageway that results decreases the flow of oxygen-rich blood through the heart, which can increase the risk for angina. 

Arteriosclerosis characterized by irregularly distributed lipid deposits in large and medium-sized arteries; such deposits provoke fibrosis and calcification (hardening of the arteries)
