Unstable angina requires general treatment, use of drugs for anti-myocardial ischemia, anti-platelet, anti-coagulation and other treatments, and intervention and surgery if necessary. 1. General treatment: bed rest, oxygen intake, and monitoring of vital signs. 2. Drug therapy: Nitroglycerin, metoprolol, esmolol and other drugs can be used to reduce myocardial oxygen consumption and dilate coronary artery to relieve myocardial ischemia. At the same time also need to take aspirin, clopidogrel and other anti-platelet drugs can inhibit the formation of platelet thrombosis. The use of heparin or low molecular heparin and other anticoagulant drugs can prevent thrombosis and progression to myocardial infarction; the use of atorvastatin and other statins can play a role in anti-inflammation and stabilization of plaques the use of drugs such as captopril, temsirolimus and other drugs can reduce the incidence of cardiovascular events. 3. Reconstruction of coronary artery blood flow: Generally, patients with unstable angina need to undergo percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) to reconstruct coronary artery blood flow. PCI is commonly known as stenting, and CABG is commonly known as bypass grafting. Specific treatment options need to be further evaluated on a patient-by-patient basis, such as short-term risk stratification, etc. It is recommended that patients consult their specialists to choose the appropriate treatment and take medications as prescribed by their doctors.
