Arteriosclerosis refers to the hardening of an artery wall, while Atherosclerosis refers to the narrowing of an artery due to the build-up of plaque. A patient may have hardened arteries without plaque, however atherosclerosis indicates the presence of arteriosclerosis.
Plaque is made up of cholesterol, calcium and other substances found in the blood. Over time, plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs, limbs and other parts of your body. More commonly plaque can cause problems if it ruptures, sending debris into the arterial tree causing blockages downstream.
