Coronary artery heart disease (coronary heart disease) is the most serious cardiovascular disease that jeopardizes the health of human beings, and its high morbidity, high mortality rate, and incurable characteristics have become one of the important research topics of medical work. In the past thirty years, the diagnosis and treatment of coronary heart disease has made great progress, in terms of diagnosis, more clear and specific, and the treatment method is more comprehensive and feasible. In particular, the development and popularization of coronary stenting has made the treatment of coronary heart disease more timely and efficient, and has saved many patients’ lives. With more and more patients after stenting, the alertness of some patients will become more and more diluted, thinking that this treatment is too common, less painful, faster recovery, easy for doctors to complete, hospitals are happy to do, and the cost of patients can be accepted. In fact, it is not, here, I want to emphasize the coronary stenting after a few issues that can not be ignored, hope that everyone will benefit from it. First of all, coronary stenting is not the end of treatment for patients with coronary artery disease, but the beginning of treatment for patients with coronary artery disease. Most patients with coronary artery disease come to the hospital with angina pectoris or myocardial infarction for the first time, and due to the needs of their condition, stenting is completed, thus avoiding the adverse consequences of an acute cardiac event. However, as far as the disease itself is concerned, the most important treatment is the one that addresses its cause. The development of coronary artery disease has its own risk factors, which requires post-stenting patients to strictly control the risk factors of coronary artery disease, such as establishing a healthy lifestyle, quitting smoking and limiting alcohol consumption, eating a reasonable diet, strengthening exercise, controlling body weight, and having a regular work routine; and reasonably screening and treating existing hypertension, dyslipidemia, and diabetes mellitus. To complete these tasks, it is recommended that patients should go to the hospital for consultation, and need a specialist to help you provide reasonable diagnosis and treatment advice. Secondly, there are some necessary medications. After coronary stenting, at least one year of dual antiplatelet drug therapy is needed to prevent thrombosis within the stent. At present, the routine use of drugs is aspirin combined with clopidogrel bisulfate, one year later by the specialist’s advice and then make adjustments, if there is no contraindication, a single antiplatelet drug needs to be lifelong; statin lipid-lowering drugs have a clear anti-atherosclerotic effect, the embodiment of this effect to the control of low-density lipoprotein at 1.8 mmol/L or less for the purpose of, if there is no contraindication, need to be taken for a long time; antihypertensive drugs and Antihypertensive drugs and hypoglycemic drugs are selected to facilitate the treatment of coronary heart disease as a principle, at the same time, some of the necessary drugs for secondary prevention of coronary heart disease, such as the patient can tolerate, but also need to be taken for a period of time. These principles and contraindications need to be formulated by experienced doctors, and it is best to visit the doctor regularly and make timely adjustments according to the necessary test results. Finally, it is emphasized that drug treatment will inevitably produce some adverse reactions, such as discomfort, must see a doctor in a timely manner, do not blindly stop the drug for a long period of time or modify the treatment plan, may bring serious consequences to the treatment of the disease.
