As a milestone in the development of modern cardiovascular medicine, stenting does play a very important value in the treatment of coronary heart disease. Completely degradable stents have brought a new revolution to the interventional treatment of coronary heart disease. But can fully degradable stents really be a boon for cardiovascular patients? 1.Why should stents be put in coronary heart disease? (1) Coronary artery disease is usually treated with stent implantation when the coronary artery stenosis is greater than 70% and there are symptoms, stenting is very helpful for the opening of blood vessels, and it is less traumatic and quicker to recover. (2) In some emergency situations such as acute myocardial infarction, stent implantation is also needed to open the vessel as soon as possible. After the narrowing and blockage of the coronary arteries supplying the heart, stenting is to open the blood vessel. Often, a simple balloon dilation may not necessarily bring the vessel to a fully dilated state, and a stent is needed. The stent is a metal mesh structure, which will play a supporting role and keep the blood vessel open for a long time. 2.What is cardiac fully degradable stent? At present, cardiac stents are mainly divided into two types: non-degradable stents and fully degradable stents, fully degradable stents are the new type of stents that have appeared on the market only in recent years, and the main advantage is that they can be degraded and absorbed. The mechanical strength of stents is not as strong as that of metal stents, and there is a risk of brittle fracture and deformation. Not all stenotic vessels can be treated with fully degradable stents, which have their limitations and are not suitable for some small vessel disease, complex lesions and calcified lesions. 3.How to treat coronary heart disease? Regardless of whether stents are placed or not, whether permanent stents or fully degradable stents are placed, lifestyle changes must be adhered to, in addition to the need to take long-term coronary heart disease drugs, because freezing three feet is not a day’s cold, vascular disease is a gradual aging process, we can not ignore our lifestyle and drug-based treatment, based on this regular review in order to keep healthy forever. The final summary to everyone. Fully biodegradable stents are only a boon for certain suitable patients with coronary heart disease, and there are still some limitations for some of them. Not all patients with coronary artery disease need stenting, and not all lesions requiring stenting can be treated with fully biodegradable stents, which need to be evaluated on a case-by-case basis. We hope that we should look at these news or propaganda correctly and not make blind judgments, regular hospital examinations, and the choice of treatment options still needs to be judged by clinicians. The wisest choice is to listen to the professional advice of the doctor.
