Coronary artery Disease (CAD) is when there is build up of plaque within the arteries of the heart. Coronary arteries are blood vessels of the heart that pump blood to the outer part of the thick heart muscle wall. If the artery wall of the vessel were damaged, cholesterol would begin to deposit into the damaged wall. The white blood cells would follow after to remove the build up of cholesterol leading to an inflammatory response. Repeated inflammatory responses would lead to blood vessels becoming hard and stiff and this is called atherosclerosis. Overtime, the combination of cholesterol and white blood cells would create a fatty bulge, or plaque, in the vessel. The plaque creates a problem for the blood trying to pump through them to get
