The greatest advantage of cardiac stenting is that it can effectively address coronary stenosis while avoiding the physical trauma associated with surgical procedures. Cardiac intervention is short, recovery after surgery is fast, complications are few and risks are small, especially after the emergence of drug stents, which became a milestone in the history of cardiac intervention. Drug stents may significantly reduce the symptoms of coronary artery disease significantly and reduce the possibility of reoperation with more significant efficacy. Nowadays, drug stents are the main stents used in clinical practice, and more than 95% of coronary intermediate treatments in China are chosen to be drug stents. Drug stents usually consist of three parts: metal stent carrier, drug release carrier (divided into two categories: absorbable and non-absorbable) and drug. Classified by the drug carried by the stent, the most widely used drug stents are divided into rapamycin drug stents and paclitaxel drug stents, as well as stents using drugs such as Erolimus and ABT-578. Now there are more and more types of stents, is it better to use domestic or imported cardiac stents for cardiac intervention? According to the current clinical follow-up, there is no big difference between the actual efficacy of domestic stents and imported stents, and the effectiveness and safety are similar. For example, for elderly patients with large blood vessels or over 80 years old, the application of cheap bare stents is more effective. In most cases, domestic stents can basically replace imported stents. If the economic condition is not very good, it is not necessary to implant imported stents, and domestic stents are sufficient to achieve the therapeutic effect well. Before stent implantation, coronary angiography should be performed to clarify the degree, nature and location of coronary lesions in order to select the appropriate stent to achieve good therapeutic results. The following lists the current cardiac stent prices for reference, the actual price can fluctuate with the brand and model: domestic drug stents are now the most widely used: the minimally invasive Firebird stent, the Excel stent from Givi and the Nano stent from Lopez, as well as the Helios stent and the BUMA stent, etc. The cost is about 12,000-15,000 yuan, and at present, most hospitals use Abbott’s Xience Prime stent costs about $22,000, Poco’s Promus Element stent costs about $20,000, and Medtronic’s Endeavor stent costs about $20,000. It should also be noted that patients with obvious angina symptoms, acute myocardial infarction, patients with recurrence of angina after surgery and patients with large myocardial ischemia need to undergo cardiac interventional procedures based on relevant examination reports. Although cardiac interventional therapy is one of the effective methods to solve coronary heart disease, it is by no means a once-and-for-all solution. In other words, long-term prevention, including active medication and lifestyle modification, is essential to protect the cardiovascular system, regardless of whether interventional treatment has been performed or not. It is essential to strengthen the awareness of daily life prevention of coronary heart disease.
