Choosing what stent to use to treat a disease is not as simple as choosing a piece of clothing, or choosing a piece of furniture. It is necessary to consider the patient’s age, gender, vascular condition, lesion site, combination of other diseases, whether to take anticoagulants for a long time, etc. At present, there are two major types of stents in our medical market, domestic and imported, and 2 major types of drug stents and bare metal stents in terms of whether they carry drugs or not. In terms of the nature of the stent metal, there are 2 types of stents: 316 stainless steel and t alloy. Drug stents are divided into 2 major categories of rapamycin and paclitaxel from the type of drug loading, and three categories of drug loading methods, such as drug film loading, degradable drug film loading and drug-free film loading. The main functions of stents are: 1) good support, 2) good therapeutic effect (anti-stenosis and restenosis) and 3) good long-term safety effect (no thrombosis). Everyone talks about the safety of stents and believes that the safest stent is the bare metal stent. However, the restenosis rate of metal bare stents has been very high, and the national population does not accept this kind of stent. From the comparison of current data, all drug stents used in our market have good inhibition of restenosis and also have good long-term safety. The treatment response of national people to stents is generally better than foreign ones, and various indicators are better than foreign ones, which at least indicates that the stents developed independently in China are not inferior to foreign ones in terms of performance and quality. Coronary artery disease is a very complicated disease, but the people have high demands, asking for a one-step cure at once. Instead of putting great pressure on our doctors, it is more demanding for the products of national enterprises. Our national enterprises have made amazing achievements in various fields, and in the medical field is no exception, the domestic stents have stood the test, and more and more patients are giving the choice to doctors and choosing domestic stents. Everything is not 100% perfect, especially the treatment of disease, but how to reassure the patient, how to reassure the family, is a problem that doctors must consider.
