Coronary thrombosis, more commonly known as heart attack in popular parlance, is a thrombosis or blockage that disrupts the coronary circulation in a human body. This, in turn occurs by the blocking of blood supply to the heart muscles due to the development of a blood clot in one of the coronary arteries. A person suffering from coronary thrombosis will feel acute chest pain behind the breast bone that more often than not radiates towards the left arm.

Unless this thrombosis is removed quickly with medication or heart surgery, the affected heart muscle will not get enough oxygen and cease functioning. The main cause of coronary thrombosis is deposit of fat or cholesterol on the wall of the arteries that harden and become narrower over the course of time. This also affects their elasticity and obstructs the blood flow to the heart muscles. People with high cholesterol levels or those suffering from diabetes and hypertension are at a greater risk of coronary thrombosis.
