Blood Clot From Coronary Angiogram

Blood clots are generally formed to stop bleeding, as in the case of an injury. When a blood vessel is injured, then the blood cells and the fibrin strand rapidly form a clump to stop the bleeding. This is a natural process in case of an injury. But, when the blood clot forms even when the person is not injured, then it is a pathological condition which needs to be checked. This is because such kind of blood clots may not allow the flow of blood through an artery or a vein.
