If a blood clot develops in one of these arteries, the blood supply to that area of the heart muscle will stop. This is known as a heart attack, or in medical terms a coronary thrombosis or myocardial infarction. A heart attack will cause severe chest pains behind the breast bone, often radiating towards the left arm.

The coronary arteries carry oxygen- and nutrient-rich blood to the heart, which allows it to pump and supply blood to the body. The coronary arteries can become blocked by various processes related to cholesterol (atherosclerotic) or other causes (nonatherosclerotic), which can cause heart attacks when the blockages are severe enough to impede blood flow to the heart. . This focuses on spontaneous coronary artery dissection (SCAD).

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.
