Coronary Artery Disease (CAD)
Coronary artery disease is also called heart disease or atherosclerosis. It is
the hardening of the blood vessels by fatty deposits called plaque.

The heart must get oxygen and nutrients to work well. Blood carries the
oxygen and nutrients to the heart through the blood vessels called arteries.
As the plaque builds up, blood flow to the heart muscle is decreased. When
blood flow is decreased, it can cause chest pain, shortness of breath, or a
heart attack to occur.
