The difference between myocardial infarction and angina pectoris

Myocardial infarction is caused by acute and persistent ischemia and hypoxia of coronary arteries. It is a disease that can be complicated by arrhythmia, shock or heart failure. Angina pectoris is a clinical syndrome dominated by paroxysmal chest pain or chest discomfort. It is caused by absolute or relative insufficiency of myocardial blood supply.
