The main drugs that need to be taken for a long time after coronary stenting are antiplatelet aggregating drugs, lipid-lowering drugs, beta-blockers and ACEI/ARB drugs. 1. Antiplatelet aggregation drugs: these drugs are used to prevent the formation of blood clots. Commonly used drugs are aspirin, clopidogrel, tegretol and so on. There is a risk of bleeding when taking this kind of drugs, and you should pay attention to the presence of bleeding gums, subcutaneous petechiae and ecchymosis, resolving black stools, hematuria, etc. in your daily life.

Commonly used drugs are atorvastatin and resuvastatin. The main adverse effects of these drugs are liver damage and rhabdomyolysis. Therefore, liver function and creatine kinase need to be monitored while taking these drugs. 3. Beta-blockers: These drugs reduce myocardial oxygen consumption, improve cardiac function, improve prognosis of coronary artery disease and reduce hospitalization by slowing down the heart rate. Commonly used drugs are metoprolol, bisoprolol and so on. This kind of drug can reduce blood pressure, reduce heart rate, induce bronchial asthma, for the combination of bronchial asthma, blood pressure lower than 90/60mmHg, heart rate lower than 60 beats / min of people use this kind of drug with caution. 4. ACEI/ARB drugs: these drugs help to improve myocardial remodeling, reduce the death rate. Commonly used drugs include captopril and irbesartan. Common adverse effects of these drugs are cough, hypotension, hyperkalemia and so on. Coronary stenting often requires lifelong medication, which should be used under the guidance of a medical professional, and should not be reduced or discontinued on its own.
