How much do you know about health?
Cardiac stents, also affectionately known as coronary stents, are a powerful tool in cardiac interventional surgery. It is responsible for unclogging arteries and blood vessels, and always guards our cardiovascular health. The main materials of the scaffold include stainless steel, nitinol, and cobalt-chrome, which together build this little life keeper. As early as the 80s of the 20th century, the prototype of cardiac stents appeared. From metal stents to drug-coated stents to bioresorbable stents, the development of cardiac stents is like a symphony of technology and medicine. Every progress is a reverence and care for life. 
In recent years, there has been a lot of talk about heart stents. Some people say that cardiac stents have been eliminated abroad; It is also said that after the installation of a heart stent, the person's body collapses. Are these statements true or false? Let's uncover the truth of the matter together.
Cardiac stent surgery refers to the placement of a mesh metal stent in the place where the coronary artery is severely narrowed, and the narrowed artery is opened with a balloon to restore the normal blood supply to the heart. This surgery is an important procedure for heart patients, but it is not suitable for everyone.
1. Acute myocardial infarctionThe ** bomb of this heart, once it explodes, the consequences are unimaginable.
It is a manifestation of coronary heart disease, and if it is not treated in time, the god of death will quickly approach. Damage to heart muscle cells can lead to heart failure, the ultimate lament for the heart, with a five-year survival rate as low as 50 percent. Therefore, we need to quickly perform thrombolysis or stent surgery to defend the blood vessels like a warrior guarding the castle and prevent the threat of myocardial infarction.
2. Angina pectorisThis is a common shadow in the lives of people with coronary heart disease.
Many people don't think about it, but there are many types of angina, except for labor colic, which is generally easier to control, other types of angina are more like cunning foxes that can come out and cause trouble at any time. When medication does not relieve the pain, the condition may worsen, and we need to be alert to the occurrence of myocardial infarction and, if necessary, stent surgery to ensure the unimpeded passage of life.
3. Coronary heart diseaseThe severity of the coronary artery is critically occluded.
The clinical genetic criteria are based on 50% coronary angiography, and the degree of occlusion in other stages is the key to judging the severity of the disease. If the occlusion is only 50%, we usually don't need to be overly stressed. However, medication control and life regulation are still essential, and they are like guardian angels that guard our health and help us improve our disease conditions to a certain extent.
Recently, there is a saying circulating on the Internet that cardiac stent surgery has been eliminated abroad, and people will be like wasters after it is done. But is this view true? First, let's take a look at the basics of cardiac stent surgery. Cardiac stents, also known as coronary stents, are mainly used for percutaneous coronary intervention (PCI) to improve the symptoms of patients with coronary heart disease and effectively reduce the risk of death from acute myocardial infarction. In the medical field, cardiac stent surgery is a common method. For the statement that "cardiac stent surgery has been eliminated abroad", we need to go deep into the truth behind it. Some scholars have counted the data of cardiac stent surgery in 1,000 hospitals in the United States and Japan from 2013 to 2017.
According to the data, the number of cardiac stents** received in the United States in 2013 was about 550,000, and by 2017 it had grown to 6380,000 cases.
In Japan, the number of patients receiving coronary intervention has also increased from 180,000 in 2013 to 24 in 201770,000 cases. These data clearly show that the utilization rate of cardiac stent surgery in foreign countries has not only not decreased, but has continued to increase.
To sum up, the claim that cardiac stent surgery has been eliminated abroad is complete nonsense. In fact, cardiac stent surgery is an important and widely used medical treatment, both abroad and in China. We should look at this way rationally and not blindly listen to rumors. 
When a patient has a stent implanted in the heart, it is clearly a problem with coronary artery stenosis. The main function of the stent is to ensure the safety of the patient's life and prolong the life.
In coronary artery stenosis, drug dependence** alone is not sufficient, as it may still lead to myocardial infarction. The advent of stent surgery is like a bridge to protect life, it helps to solve the problem of stenosis and prevent the condition from worsening.
Of course, not everything is resolved immediately after stent surgery. Some patients may experience myocardial ischemia, post-exertion discomfort and other problems, but these are improved to a certain extent after the stent is completed.
For those who feel tired after stent surgery, or who can no longer bear the heavy workload, it is actually closely related to the individual's physical condition.
As for those remarks that people will be "scrapped" after heart stent surgery, it is obviously unscientific. Life is precious, and stent surgery is to better protect and prolong this preciousness. I hope everyone can look at it rationally and not be easily misled by rumors. After heart stent surgery, many people are worried that their blood vessels will become clogged again. Indeed, there are many patients who are clinically exposed to such risks.
Although the placement of the stent can alleviate the condition, it is not a problem. The local use of stents can indeed alleviate the blockage of blood vessels, but if the patient continues to indulge himself, does not change his bad habits, and does not carry out correct follow-up care and **, the possibility of blood vessel blockage again becomes very large.
Therefore, after the surgery is completed, we need to consult the doctor to understand the follow-up method. At the same time, life care should not be neglected, only in this way can the risk of blood vessel re-blockage be reduced. 
1. Some patients have little understanding of the coronary stent, and are often worried about the safety of the stent before surgery. Because the stent is outside the body and placed in the heart at this critical location, the patient's psychological stress is extremely high. Even if the surgery is successful, this kind of doubt and self-scare about the internal stent often leads to abnormalities in the body, such as chest tightness, shortness of breath, palpitation, etc. 2. After the stent is placed in the coronary artery, although the blood supply to the heart can be restored, the symptoms caused by myocardial ischemia will not disappear immediately. Even if the damage to the heart muscle is not severe, it will take some time to recover. Therefore, it is normal to experience physical discomfort after surgery, and the discomfort will gradually subside as the body gradually adjusts.
3. The watershed between life and death of myocardial infarction patients lies in the timing of rescue. Patients who arrive late are at increased risk of heart failure due to severe myocardial necrosis. Even if the coronary access is opened, the necrotic myocardium cannot be recovered, and there may be sequelae. 4. Cardiac stent surgery is not a panacea, it can only dilate narrowed or blocked blood vessels, and has no effect on other diseases such as coronary heart disease. As a result, patients may still be affected by other primary diseases and become unwell after surgery. 5. Cardiac stents, as a local means, cannot be used to achieve coronary atherosclerosis. Re-narrowing and blockage of other arteries can still cause heart discomfort. 
Follow-up examinations are crucial and require detailed examinations at one month, three months, six months, and 12 months after stent surgery. These routine tests include electrocardiogram, liver function, kidney function, cardiac enzyme profile, blood lipid level, etc. Of course, we also need to flexibly adjust the examination items according to the changes in symptoms in different periods of time to ensure that there is no risk. Taking antiplatelet drugs is also a critical part of recovery after surgery. In the first year after surgery, dual platelet control** is required, which means taking clopidogrel or ticagrelor in addition to aspirin. After one year, if the condition is stable, aspirin alone can be relied on for long-term**. It is important to note that aspirin should be taken for life. Healthy habits in life have a non-negligible impact on post-operative recovery. In terms of dietary habits, you should try to avoid foods high in salt, such as pickled products, and try to eat less cholesterol-rich foods and eat more fresh vegetables and fruits. In addition, appropriate exercise is also necessary, but it is important to pay attention to the intensity of exercise and choose an exercise method that suits you, such as walking.
