The interruption of blood flow causing ischemia is usually the result of an intrinsic obstruction of major arteries by clots. Emboli that originate in the heart are the main cause of such obstructions, and patients who have had myocardial infarcts or have stenosis of the mitral valve or arrhythmias such as atrial fibrillation are susceptible to the development of clots within the heart which can lead to distal thromboembolism. Another common cause of arterial obstruction is the formation of clots in an area of narrowing caused by arteriosclerosis.
