Is it better to choose domestic or imported cardiac stents? Instead of wrestling with this, let's figure these out
There are many people who have this kind of thinking in life: you get what you get for every penny, and imports are always better than domestic ones!
It is also influenced by this inherent idea that some patients tend to consider price and import when they develop diseases and choose drugs. In terms of cardiac stents, everyone has such a concept.
Some people even mistakenly believe that choosing domestic products is for the sake of cheapness, and the more imported brackets are, the better the effect will be. In fact, from a clinical point of view, it is better to clarify the following issues first, rather than entangled in domestically imported stent surgery:
1. What is a cardiac stent?
The so-called heart stent is not a direct operation on the heart, it is a first aid measure for patients with coronary heart disease and myocardial infarction.
Due to the patient's coronary artery is affected by various factors, such as age, genetics, three high diseases , etc., the coronary artery gradually loses its elasticity, and the inner wall of the blood vessel becomes more and more narrow , which seriously affects the normal blood supply of the myocardium.
Therefore, the implantation of the stent at this time has the effect of expanding the blood vessels and providing sufficient blood oxygen to the myocardium . From a clinical point of view, it is the most effective emergency measure for cardiovascular disease that has been introduced in the past 20 years . Its original name is " coronary stent";
2. In which case is it necessary to do a stent ?
Many people mistakenly believe that as long as there is coronary stenosis, cardiac stenting is required. But in fact, the patients who really need this kind of interventional treatment only account for about 20% of the patients with cardiovascular disease .
As mentioned above, it is a rescue and preventive treatment. It is suitable for rescue within 6 hours after myocardial infarction, patients with unstable angina pectoris, and patients with coronary stenosis more than 70% .
It should be emphasized here that if the patient meets these three conditions, but the patient's blood vessel diameter is less than 2.25mm , in this case, the surgical criteria are not met. Even if a stent is placed, the treatment effect is often not ideal;
3. The material of the bracket
At present, the materials of clinical cardiac stents are mainly divided into three categories. The first is bare metal stents , which are the earliest stent types in medical applications.
The second is drug-coated stents , that is, on the basis of metal stents, drugs are applied to the surface of the stent to inhibit the proliferation of vascular endothelial cells and reduce vascular inflammation . The third type is bioabsorbable stents , which are biomaterials that can be absorbed and degraded in the human body;
4. Which one is better, imported or domestic?
It has to be said that nowadays coronary stents are indeed divided into two categories: imported and domestic. From a clinical point of view, the most fundamental difference between these two types of stents is actually the difference in price .
You know, heart stents are actually the same as drug choices, and the one that suits you is the best. Under normal circumstances, different manufacturers, different models and different lengths of stents are suitable for different .
Clinicians will consider the characteristics of the patient's own lesions, physical fitness, etc., and then recommend the patient to choose a suitable stent . As for whether the stent is imported or the process and price, it is not within the scope of clinical consideration.
5. Service life
Usually, if the patient's blood vessel is not narrowed and blocked again after the stent is implanted, the stent can be used for life.
Of course, there are exceptions to this situation. For example, the patient's blood vessel where the stent is installed proliferates, and plaque may enter the blood vessel through the stent , causing the blood vessel where the stent is installed to be narrowed again. In this case, it is necessary to undergo intervention again.
Finally, it should be emphasized that although stents can be used for life, stent surgery is not a one-time-for-all. It does not cure atherosclerosis or cardiovascular and cerebrovascular diseases, but is only a first aid measure.
Therefore, in the following life, patients also need to strictly follow the doctor's requirements for drug treatment, improve poor diet and living habits, and regularly conduct relevant re-examinations.
