We have described in the preceding paragraphs, the heart is the center ofcirculation, and pumping function.
However, to make the heart maintain normal operation, it requires energy.And for the supply of such energy, to transport nutrients and oxygen to theheart, is the cardiac blood flow path, or the coronary circulation.
The self-contained heart circulation and systemic branch of coronary arteryis responsible for. Obviously, the heart itself although it has a lot ofblood, but unable to obtain energy from the cavity of the heart‘s bloodsupply depends on coronary artery. If necrosis of myocardial ischemia incoronary artery obstruction, it is called a myocardial infarction, which isone of the major complications of high blood pressure.
