Coronary Artery Disease. The coronary arteries are the blood vessels that supply the heart with oxygen and nutrients. When there is build up of cholesterol (plaque) inside the walls of the coronary arteries, the blood flow to the heart decreases.Usually there are no symptoms when the blockage is small.his completely blocks the flow of blood in the artery. The area of heart muscle supplied by that artery then becomes damaged due to lack of oxygen and nutrients. Blockages of any size can cause a heart attack (myocardial infarction).Coronary artery disease is very common throughout the world.
