The coronary arteries supply blood to the myocardium (heart tissue) itself: e.g., coronary capillaries deliver oxygenated blood (nutrients) to all of the heartâs cells.
Through these arteries, called the coronary arteries, the heart muscle (myocardium) gets the oxygen and other nutrients it needs to pump blood. The plaque often narrows the artery so that the heart does not get enough blood. This slowing of blood flow causes signs and symptoms of chest pain, or angina.
