There is often severe and persistent retrosternal pain in clinic, which cannot be completely relieved by rest and nitrate drugs, accompanied by increased serum myocardial enzyme activity and progressive electrocardiogram changes, which can be complicated by arrhythmia, shock or heart failure, and often life-threatening. This disease is most common in Europe and America, with about 1.5 million people in the United States suffering from myocardial infarction every year.
