Some people say that cardiac stents have been eliminated abroad for many years, so why are they widely used in China?

Cardiac stents are eliminated abroad? This statement is wrong, even in foreign countries, the more widely used technology still refers to the stent, which has not been replaced by new technology. For people with serious conditions, every minute and every second counts.

The sooner the blood vessels are opened, the better the relief effect, and stents are the fastest and most effective method. Otherwise, timely assistance may not be obtained, affecting life safety.

I have to say that in order to get traffic, the contradiction is exaggerated into a new technology concept, the method of suction, in fact, has been there for a long time, but there is no mention of the dredging of the stent, and it is not suitable for all people, the thrombus is withdrawn in time, and the unstable plaque still exists, and in most cases, it still needs support.

For people with serious conditions, every minute and every second counts. The sooner the blood vessels are opened, the better the relief effect, and stents are the fastest and most effective method. Otherwise, timely assistance may not be obtained, affecting life safety.

After learning about the existence of this technology, many people are asking whether heart disease patients can avoid the use of stents in the future. Of course, the answer is no, although the new technology of thrombus removal is very much expected. If the technique is mature, the placement of the stent can be avoided, but the ideal is very plump, the reality is very skinny, and the effect of thrombus aspiration surgery is not ideal.

In addition, thrombus aspiration is not suitable for all patients. For middle-aged and elderly people with weak physique, the risk of this surgery is relatively large, and it will cause very serious *** if you are not careful. Vascularization only targets the blood clot inside the blood vessels, but the plaque inside cannot be removed, and there is still a risk of blockage if there are too many plates in the blood vessels.

Therefore, stents are currently a more reliable solution to the problem of vascular blockage. The main materials are: metals (nichrome, titanium, chromium, etc.), coatings and soluble materials.

For example, a heart stent is actually an empty tube that can be implanted into a blood vessel to open and relieve blocked blood vessels.

Because at the moment it is a relatively good product, it can save some lives, so it will be used.

This is because cardiac stents can indeed save some people's lives, so it will be widely used.

Because the incidence of coronary heart disease in China is getting higher and higher, and cardiac stents can effectively reduce the mortality rate of the disease, they will be widely used.

Although our surgeries are gradually perfecting and any system can ensure the normal operation of our body, we have to admit that some surgeries themselves are more harmful to our body, which is precisely because there are many obligations to intervene, so that our body can not adapt in time.

When it comes to heart stents, I'm afraid many people will not be unfamiliar. Cardiac stent, also known as coronary stent, is a commonly used medical device in cardiac interventional surgery, which has the effect of unblocking arteries and blood vessels. In fact, cardiac stent surgery was only introduced into China from abroad in the early 80s of the 20th century, it is a very thin and very small metal mesh, when the coronary artery supplying blood to the heart is blocked, and the acute myocardial infarction suddenly occurs at the critical moment, the narrow blood vessels are stretched open with this metal mesh, and the heart gets blood **, and the ischemic myocardium immediately gets blood supply.

Because the stent can "open" the blocked blood vessels, quickly relieve the symptoms, and the effect is remarkable, it was once considered to be the "artifact" of coronary heart disease.

The reason why the heart stent is gradually coming off the altar is because this kind of surgery cannot fundamentally ** coronary heart disease. In fact, cardiac stents do not fundamentally eliminate plaque, let alone prevent it from continuing to grow, but only squeeze the plaque to the side. The damage caused by the stent to the intima of the blood vessel will cause inflammation, platelet aggregation, plaque and thrombus will come back over time, and the place where the stent is placed will still be blocked.

Most importantly, in order to prevent secondary blockage caused by cardiac stents, patients need to take lifelong medication, and they are taking "anticoagulants". In fact, under normal circumstances, the bleeding and coagulation process of blood are in dynamic equilibrium, but once a person takes anticoagulants for a long time, due to the intervention of this external factor, it is bound to break this balance, and the blood will not coagulate when it should be coagulated, which is the direct **** of the heart, which is also very fatal.

In fact, although the heart stent is very large, it is also a very effective means of coronary heart disease, if the patient's coronary artery is severely narrowed, myocardial infarction or angina pectoris may occur at any time, and the stent needs to be placed according to the situation. In short, cardiac stents are a life-saving "weapon". Cardiac stents do affect the life of patients, but it also depends on postoperative maintenance, if properly maintained, basically no different from normal people, for example, academician Zhong Nanshan in 2004 suddenly had a heart attack and underwent stent surgery, now he is 83 years old, his physical condition is still very good, it can be seen that heart surgery is very successful.

In fact, there are alternative medical methods for cardiac stent surgery, the first alternative medical method is thrombolysis**, in fact, the best thrombolytic drugs and stents are comparable in price, and will not be cheap to go there, according to relevant data, within 3 hours of acute myocardial infarction, the effect of thrombolytic drugs to open blood vessels and stents to open blood vessels is basically the same; After 3 hours, the opening rate of thrombolytic drugs decreased significantly. In contrast, the success rate of cardiac stent opening blood vessels, even if it takes a long time, is still quite high, and basically in the acute myocardial infarction stage, the success rate of opening blood vessels is not different in time. All in all, there are only two ways to treat acute myocardial infarction, one is cardiac stents and the other is thrombolysis, which can be used to prevent thrombolysis as much as possible.

Because the heart stent is a metal thing, many other accidents will occur after being implanted into our body, so it has been gradually eliminated, and now most of them choose the way of heart bypass, because this way chooses the blood vessels in our body, which is safer.

Heart stent is to implant external things into the body, which will cause rejection in the body and accidents, and now heart bypass surgery is gradually replacing heart stents, because heart bypass surgery is to use its own blood vessels, do not implant foreign objects, and build rejection. Thus being more secure. In order to reduce the occurrence of heart disease, we can reduce smoking and drinking, reduce fat intake, and reduce the burden on the heart.

Cardiac stents have been gradually eliminated, mainly because this method is relatively backward, and the stent is not something inside the body, it is a foreign body, and it is easy to cause discomfort, so now there are generally more ways of heart bypass surgery, of course, this method will be more difficult, and now there is also a variable filter surgery to keep the blood flowing normally.

Because cardiac stents can no longer keep up with the development of the times, it is now the era of science and technology that can be replaced by high-tech medical methods.

Cardiac stents have been phased out in the United States? What other scientific myths have fooled you?

2. What do cardiac stents mean now for patients with heart disease? After the efforts of all aspects of our country, the heart stent has now been reduced to the acceptable range of the general public, which also shows that China is constantly promoting the heart stent in this way, so that more patients with coronary heart disease can live an ordinary life, so the heart stent is like a life-saving straw for patients with coronary heart disease, so heart disease, and because of other ways, it can not be completely ** for this disease, and for manpower, Financial resources are a very big damage, so cardiac stents are the most affordable and effective means for these patients with coronary heart disease and heart disease.

This is not true, cardiac stents are still an important means of medicine, and there are many scientific rumors in life, such as energy-saving lamps used at home can lead to the occurrence of cancer and are highly toxic, which has no scientific basis at all, in fact, it is a rumor, and for example, coffee containing carcinogens will lead to the occurrence of cancer after application, in fact, this is also a very exaggerated statement, I hope people must be rational in the face of these scientific rumors.

Cardiac stents have not been eliminated in the United States. The United States has developed a number of devices that can be used for cancer. These are all fake scientific rumors, and many of the current lace news and bad weekly magazines are just false news to mislead some people.

Cardiac stent as the most frequently used medical equipment for heart disease, now the demand for use is increasing, its use can dredge arteries and blood vessels, effectively reduce the incidence and mortality of heart disease, some families because of economic difficulties, can not afford to install cardiac stents, resulting in heart death, but now such a scene no longer exists, because of the average price of about 700 yuan, most patients can afford it, so I think this is very good news.

Many people are also worried that such a large price reduction will feel that the quality of the stent is not good, so that heart patients dare not use it, I don't think there is any need to worry, the relevant departments have said that the material purchase has been carefully considered, and relevant tests have also been carried out, which can ensure the effectiveness of the product, and at the same time, in the later production process, the management will be increased. Ensure the effective use of cardiac stents.

Imported stents mainly have relatively good technology and can do drug coating. Specifically, in terms of use, the possibility of re-occurrence of thrombus at the stent is reduced, and the probability of mechanization is reduced.
