The heart is surrounded by three major coronary arteries that supply blood and oxygen to the heart muscle. If you develop a blood clot in one of these arteries is interrupted blood supply to areas of the heart muscle. This is a coronary thrombosis.
Usually produces an intense pain in the chest behind the sternum (breastbone), which often extends to the left arm. The area of muscle that is not enough supply stops working properly, if not quickly dissolve the blood clot, for example, a drug that dissolves the clot (thrombolysis). Why produce coronary thrombosis?
Coronary thrombosis, which usually occurs in the coronary arteries, develops, often in the place where an atherosclerotic plaque ruptures. Most people in the developed world suffer from atherosclerosis (hardening of the arteries) in some parts of the body without even realizing it. Atherosclerosis can begin about twenty years and develop gradually as they get older.
Some people have symptoms of atherosclerosis in the coronary arteries, which are shown as angina pectoris (chest pain). By contrast, the plaque rupture leading to coronary thrombosis often occurs in people without a previous history of angina pectoris.
The lining of the artery that supplies irrigation to the heart muscle is forming the atherosclerotic plaque. If you break the diseased coronary artery may develop a blood clot, which consists of blood-clotting proteins, platelets and red cells. This training can disrupt the blood supply, and is called the blood clot.
