Coronary intervention is one of the effective means to treat coronary heart disease, and the medication after intervention is directly related to the patient’s safety and long-term prognosis. First of all: patients should have a correct understanding of coronary heart disease and interventional therapy. Coronary heart disease is a lifestyle disease, and so far, the cause of the disease is unclear, and there is a lack of effective means of cure. Although a stent is implanted, it only mechanically opens the diseased vessel and restores coronary blood flow. Therefore, stenting is not a once-and-for-all technology, and post-stenting requires comprehensive control of coronary heart disease risk factors and improved prognosis on the basis of comprehensive lifestyle improvement. Secondly, the following drugs should be used for a long time after stenting: 1. drugs to control the risk factors of coronary heart disease or the accompanying diseases: such as hypertension, diabetes, hyperlipidemia, etc. 2, platelet inhibition drugs: advocate the use of dual anti-platelet drugs: one is aspirin, 100 mg per day, both morning and evening; the second is clopidogrel, 75 mg per day, once every morning. It is recommended that aspirin be taken for life, and clopidogrel for at least a year to a year and a half, for high-risk patients patients with high recurrence of cardiovascular events can take clopidogrel for a longer period of time. 3, lipid-lowering drugs: commonly used drugs are simvastatin, pravastatin, atorvastatin, etc. The correct choice of preparation and dose should be made under the guidance of a doctor. It should be pointed out that patients with coronary heart disease need to control their lipids to a lower level than normal in order to maximize the prognosis of patients. Therefore, the reference value attached to the laboratory test sheet should not be used to determine whether to take lipid-lowering drugs or not, nor should it be used to measure whether to meet the standard or stop the drugs. 4. Drugs that stabilize the cardiac activity and improve the prognosis of the original period. For example, studies have found that beta-blockers such as medocin or bisoprolol can reduce the occurrence of malignant arrhythmias in patients with coronary artery disease and may improve heart function, but the drug should be taken under the guidance of a doctor. 5, some other drugs: sometimes the doctor will also prescribe some drugs to protect the gastrointestinal tract, such as omeprazole, pantoprazole, ranitidine, etc.; drugs to dilate blood vessels, such as nitrates, etc.; drugs to improve myocardial metabolism, such as trimetazidine, etc.; anti-vascular spasm drugs, such as Hepesol, etc.; and cardiac diuretic drugs to improve heart failure, etc. These should also be added and deleted under the guidance of a doctor. Finally: Patients with coronary heart disease should be followed up regularly. Generally, the follow-up period after surgery is defined as 1 month, 3 months, 6 months, 12 months, and then every 6 months to a year even if there are no symptoms, and even if there are symptoms, they should be followed up.
