Principles of atherosclerosis medication include controlling blood lipids, antiplatelet aggregation, anticoagulation and thrombolysis, improving ventricular remodeling, and improving symptoms. 1. Lipid control: the main pathogenesis of atherosclerosis is the formation of atherosclerotic plaques by elevated blood lipids, which causes atherosclerosis and stenosis. Lowering blood lipids can slow down the progress of atherosclerotic plaques and achieve the purpose of etiologic treatment. Usually, statins are used, such as atorvastatin and pitavastatin. 2. Antiplatelet aggregation: atherosclerosis, accompanied by vascular endothelial damage, can promote intravascular coagulation. Aspirin, clopidogrel and other anti-platelet aggregation drugs can prevent thrombosis. 3. Anticoagulation and thrombolysis: when atherosclerosis, blood is in high coagulation state, heparin, warfarin and other drugs can be used as prescribed by the doctor for anticoagulation treatment to prevent thrombosis. After thrombosis, streptokinase, alteplase and other drugs can be used for thrombolysis as prescribed by doctors. 4. Improvement of ventricular remodeling: When atherosclerosis occurs in the coronary arteries, the development of the disease can cause ventricular remodeling, resulting in irreversible damage. The use of drugs such as captopril and valsartan as prescribed by the doctor can improve ventricular remodeling and reduce the risk of myocardial infarction and other dangerous diseases. 5. Improvement of symptoms: Symptoms of atherosclerosis vary depending on the location of the lesion. Drugs such as nitroglycerin and betalactam can relieve symptoms such as chest tightness, chest pain and palpitations caused by atherosclerosis. When atherosclerosis occurs, you should seek medical treatment in time and choose the appropriate treatment after examination and evaluation by a doctor to avoid delay.
