Coronary acute coronary syndrome is an emergency in cardiology, and it is important to go to the hospital as soon as possible after the onset of the disease. After the acute myocardial infarction is clear, coronary angiography should be done as early as possible, and appropriate patients are then PCI. Early, adequate and continuous opening of the infarct-related vessels is the key to myocardial infarction treatment.
