AMI stands for acute myocardial infarction, which is an acute and serious cardiovascular disease. When a patient is considered to have an acute myocardial infarction, coronary angiography must be actively performed, and if necessary, a coronary stent needs to be installed. For patients who cannot undergo coronary intervention, urgent coronary artery bypass grafting can be considered. If the patient is too ill to undergo surgery, he or she must be actively treated conservatively with drugs, combined with dual antiplatelet and anticoagulation therapy, such as subcutaneous injection of low molecular heparin. Patients are also advised to take oral aspirin and clopidogrel. In addition, intensive lipid-lowering therapy, i.e. oral lipid-lowering drugs such as atorvastatin and rasulvastatin, should be taken. This is combined with lifestyle interventions to help prevent complications after acute myocardial infarction.
