In order to effectively improve the patient's condition and prolong their survival time, doctors often recommend patients to undergo cardiac stent surgery, which is a commonly used cardiovascular method, which is based on the principle of dilating the narrowed coronary arteries through stent implantation, thereby improving the blood supply to the heart muscle.
For those patients with severe coronary artery stenosis and poor drug efficacy, cardiac stent surgery is an effective means to significantly improve the patient's condition and quality of life.
Of course, there are certain risks associated with any surgery, and cardiac stent surgery is no exception, but many people think that the heart stent is finished when the person is installed, is this statement true or false?
Cardiac stent is a medical device that has the effect of unblocking coronary arteries, its main role is to improve the problem of insufficient blood supply to the heart, when the coronary artery stenosis or plaque rupture causes insufficient blood supply to the heart, doctors will consider placing a cardiac stent for the patient.
By placing stents, the blood flow of the coronary arteries can be restored, thereby improving the patient's heart function, however, there have been many cases of cardiac stent abuse in China in the past, and some doctors will sell stents to patients who do not need to have cardiac stents placed for personal gain.
There are even some patients who have as many as 7 stents implanted in their bodies, which is undoubtedly excessive, and this unreasonable abuse not only brings a financial burden to patients, but also easily leads to problems such as thrombosis regeneration and blood vessel re-narrowing in the body.
In order to solve this problem, China has taken a series of measures, the most striking of which is the implementation of the average price reduction policy of cardiac stents in many places, which makes the first stents from the original 130,000 yuan dropped to an average of 700 yuan, an overall drop of 93%, which greatly reduced the financial burden of patients and allowed more patients to enjoy high-quality medical services.
At the same time, ** has also strengthened the supervision of doctors, strictly regulated the use of cardiac stents, and doctors need to strictly assess the patient's condition to ensure that only patients who really need to have a stent placed can receive it.
In addition, the supervision of medical institutions has been strengthened to ensure that patients have access to safe and effective medical care.
Acute myocardial infarction
For patients with acute myocardial infarction, stent implantation is a common method, which can save the dying myocardium, reduce complications and improve prognosis by stretching the coronary arteries open through a stent to recirculate blood.
Coronary artery stenosis
When the coronary arteries are severely narrowed, resulting in insufficient blood supply to the heart muscle, stent implantation can dilate the blood vessels and improve the blood supply to the heart muscle.
Complex coronary artery disease
For some complex coronary artery lesions, such as coronary artery bifurcation lesions, coronary artery calcification lesions, etc., stent implantation can improve the success rate of surgery and reduce the incidence of complications.
Re-stenosis after coronary artery bypass grafting
For some patients who have undergone coronary artery bypass surgery, if the graft is narrowed again, stent implantation is an effective method to restore blood flow and prolong the patient's life.
There is a lot of news on the Internet that the country is gradually stopping heart stent surgery, saying that the reason is that the risk of the operation is too high, and there are even reports from Beijing TV that China has gradually stopped installing heart stents, and will adopt a method of removing hard lumps in the heart and blood vessels through round-trip grinding.
As soon as this news came out, it immediately aroused heated discussions among the majority of netizens, especially the attachment of a section of surgery, which made the popularity of this topic skyrocket.
However, this seemingly credible news is actually just a rumor, the chief physician of the cardiovascular department of Beijing Anzhen Hospital affiliated to Capital Medical University pointed out that the blood vessels shown in ** are more like organs connected to the ureters, that is, the plaque in the broken kidney in the body looks like a stone, so this is actually a process of lithotripsy, rather than the removal of vascular plaque on the Internet. 
In addition, the data released by the National Organization ** Joint Procurement Office for Medical Consumables also provides us with strong evidence.
Data shows that from January to August 2021, 1.1 million cardiac stents were used in medical institutions, an increase of 54% over the same period last year, and this data clearly tells us that the demand for cardiac stents is still high and has not been eliminated.
Cardiac stent has an irreplaceable role in medicine, it can help blood vessels dilate, improve heart disease symptoms, and have a positive impact on human health, so the rumors of phasing out cardiac stent surgery in China are completely nonsense.
Rejection refers to a kind of rejection reaction by the body to foreign substances, which usually occurs in the process of organ transplantation. However, during stent placement, the stent is treated as a part of the body and therefore rarely causes rejection.
Stents do carry a risk of rejection and allergy in the body, but this is extremely rare, and in clinical practice, the incidence of metal allergy may be less than 1 in a million.
More importantly, most of the metal materials currently used to make stents are alloys such as cobalt, chromium, nickel, and vanadium, which have very good structural compatibility and almost no rejection.
Regarding cardiac stent surgery, many people have a misconception, thinking that the installation of a cardiac stent means that a person's life has come to an end, however, in fact, cardiac stent surgery is an effective means to help patients restore the normal function of the heart and reduce the risk of adverse cardiovascular events in the future.
The principle of cardiac stent surgery is to open the narrowed or even blocked blood vessels by implanting a stent, so as to restore normal blood circulation and provide sufficient blood supply to the heart.
The results of the study showed that patients who received cardiac stent surgery with appropriate medications** could significantly reduce mortality in the next 10 years, and for patients who received the best drugs**, the 10-year mortality rate could be reduced by 53%, indicating that cardiac stent surgery combined with drugs** can effectively improve the survival rate and quality of life of patients.
It is worth noting that the sudden death rate of patients with acute myocardial infarction is as high as 20% to 50% if not received in time**, however, the mortality rate can be reduced to less than 5% after receiving cardiac stents**, which fully demonstrates the positive effect of cardiac stent surgery in saving patients' lives and reducing the risk of adverse cardiovascular events.
Therefore, for patients who need to undergo cardiac stent surgery, they should choose a professional medical institution and an experienced doctor for the surgery.
In conclusion, cardiac stent surgery is an effective tool to help patients recover and reduce the risk of mortality and adverse cardiovascular events.
Cardiac stent is a common method of heart vascular stenosis, although it has many benefits, but there are also certain risks, in the process of installing cardiac stents, some complications may occur, such as catheter or stent damage, vascular perforation, thrombosis, arrhythmia, allergic reactions, etc., the incidence of these complications is generally between 1% and 5%, and in severe cases, it may be life-threatening.
After cardiac stent installation, some complications may also occur, such as infection, bleeding, vascular stenosis, poor stent endothelialization, stent displacement, stent rupture, stent thrombosis, etc.
The incidence of these complications is generally between 5% and 10%, and in severe cases, it may lead to deterioration of heart function and even death.
In addition, anticoagulants need to be taken for life after the installation of cardiac stents to prevent the formation of blood clots in the stent, but anticoagulants can also increase the risk of bleeding, especially when performing dental, surgical, neurological and other procedures.
In addition, cardiac stents can not completely solve the problem of cardiac vascular lesions, there may be stent restenosis, vascular lesions around the stent, stent aging and other problems, the incidence of these problems is generally between 10% and 20%, and in severe cases, it may cause heart disease and even death.
Therefore, before undergoing cardiac stent surgery, it is important to fully understand the risks and benefits of the surgery and weigh the pros and cons before making a decision.
The survival time after a heart stent depends on a variety of factors, including the patient's age, overall health, lifestyle, and post-operative care.
First of all, age is an important factor, generally speaking, young people recover faster and live a relatively longer life, while older people may have a relatively short lifespan due to their declining physical function and longer recovery period. But this is not absolute, as everyone's physical condition and biological age are different.
Secondly, the patient's overall health will also affect the survival time, and if the patient has other serious health problems before the heart stent is implanted, such as renal insufficiency, lung disease, etc., these factors may shorten the patient's life expectancy.
Adherence to medications**
After stent surgery, patients need to continue to take antiplatelet drugs, lipid-lowering drugs, etc., to prevent thrombosis and lower blood lipids.
Review regularly
After stent surgery, patients need to go to the hospital regularly for ECG, coronary angiography and other examinations to monitor the condition of the heart and the condition of the stent. If you have any abnormal symptoms, you should seek medical attention promptly.
Control risk factors
Risk factors such as hypertension, hyperlipidemia, and diabetes can accelerate coronary arteriosclerosis and thrombosis, affecting the effectiveness of stent surgery.
Patients should actively control these risk factors and improve their lifestyle, such as quitting smoking, limiting alcohol, eating a reasonable diet, and exercising appropriately.
Pay attention to physical symptoms
After stent surgery, patients should pay close attention to their physical condition and seek medical attention in time if they have symptoms such as chest tightness, chest pain, and difficulty breathing.
Coronary heart disease is a common chronic disease, and its method varies depending on the patient's condition, in coronary heart disease, stent implantation is a commonly used means, however, why some patients put less stents, some put more, this is a worthy question.
In fact, doctors consider a variety of factors when deciding how much stent to place for a patient.
First of all, the patient's condition is a key factor in determining the number of stents, if the patient's coronary artery stenosis is mild, only one stent needs to be placed to achieve the goalIf the coronary artery stenosis is severe, multiple stents may need to be placed to achieve the best results.
Secondly, the doctor's experience and judgment also have an impact on the number of stents, and different doctors may have different concepts and methods, so when facing patients with the same condition, there may be different options for the number of stents.
