How does vessel plaque contribute to cardiovascular disease?

Reducing blood: High lipid levels can speed up a process called atherosclerosis, or hardening of the arteries. Your arteries are normally smooth on the inside, but as you age, a sticky substance called plaque forms in the walls of your arteries. Plaque is made of lipids and other materials in your blood. As more plaque builds up, your arteries can narrow and stiffen. Eventually, reduced flow causes problems.

Blocks blood flow: Plaque either slowly blocks or suddenly ruptures and blocks the lumen of the artery and stops blood flow to any part of the body. This causes heart attack.
