Cardiac stent surgery was once considered a “miracle tool” for treating coronary heart disease in the past. As stenting became more and more widespread and mature, it was gradually deified. The overuse of some stenting procedures has led to some controversy and questions about the use of cardiac stents in public opinion and even in the medical community. In recent years, the argument that heart stent surgery is demonized began to appear in front of the public in various guises: heart stent is a time bomb in the human body, the interest of heart stent is more profitable than selling drugs, heart stent technology has long been eliminated in foreign countries …… How will the heart stent, which has gone down from the altar, face all the questions that come to its face? Is the heart stent a time bomb in the body? Some people say that after the heart stent surgery, it means that a time bomb is buried in the body, and death will occur within 3 minutes after the attack, which is faster than the 12-minute death of myocardial infarction. So, is a heart stent a ticking time bomb or not? Yes, even if there is only a one percent chance of causing a blood clot and sudden death, it is still a time bomb. But to release or not to release? It should be released, because coronary heart disease is a bomb that will explode soon, as long as the advantages outweigh the disadvantages. After stent implantation, about 5% of patients will have stenosis again at the stent, which can be solved by drugs, stenting again or coronary artery bypass, and also by using the latest drug-coated balloon to expand the stenosis; very few patients may form acute thrombosis within a year, once the formation of thrombosis is equivalent to an acute heart attack, and in fact the mortality rate of heart attack has dropped to less than 6% due to medical advances and the popularity of stenting Therefore, stents are not as scary as rumored and the risk is almost non-existent for most patients after one year. Is the interest in heart stents more profitable than buying drugs? There are rumors that stent surgery costs only$500 to$800 abroad, while domestic stents go through layers of price increases to reach patients for$20,000 to$30,000. Is it really true that it is much cheaper to have stent surgery abroad than at home? Data from the United States in 2007 showed that the cheapest bare metal stent with a relatively high restenosis rate required$800, which is just the price of a bare metal stent, plus the high cost of surgery far beyond China. Complex cases may require multiple stents, along with a combination of other operations such as rotary grinding, intravascular ultrasound, pressure guidewires, etc. High risk patients may also require balloon counterpulsation, hemofiltration, which may cost more, and the cost of doing a complex patient may be in the tens of thousands of dollars. They place more emphasis on putting the cost of care on the cost of labor and are more concerned with reflecting the value of the physician. The cost may vary greatly from patient to patient, and it is meaningless to make a simple comparison. As for the price of domestic stents, which are currently around 10,000 and some have been less than 10,000, the rumors are clearly unfounded. Cardiac stent technology has long been eliminated abroad? The rumor that the stent surgery commonly used in China was eliminated in foreign countries in the 70s and 80s, and the first human heart stent surgery was only successful in 1986, the rumor that the stent surgery was eliminated in foreign countries long ago is simply nonsense. Various medical data show that due to the small trauma of heart stent surgery and fast recovery of patients, it has developed rapidly in recent years and has now become one of the three major treatment means alongside with drug treatment and surgery. Cardiac stenting technology is still the routine and preferred treatment for most patients with coronary heart disease at home and abroad. By 1997, more than one million patients worldwide had been treated with cardiac stents. Currently, more than 1 million cardiac stents are completed each year in the United States and more than 400,000 cardiac stents are completed each year in China. Cardiac stents are misused? In the 10 years or so when stents first appeared, they were overly deified by both doctors and patients due to the small number of cases, limitations of clinical experience, and lack of guidance from relevant norms and guidelines. It once happened that patients wanted to improve the quality of their survival and took the initiative to ask their doctors to put in more stents for them, and some doctors had also advised patients to implant more stents in the hope of making their treatment results close to perfect. In recent years, physicians have come to realize that stenting should be “adequate”, but it is difficult to determine how many stents should be implanted because it is difficult to determine what is “adequate”. Which coronary lesions must be stented? 1.Acute myocardial infarction should be done as soon as possible, the mortality rate of infarction is about 15% in the era without stent, and can be reduced to 3%~6% after emergency stenting; 2.High-risk patients with obvious myocardial ischemia; 3.For more stable patients, the decision should be made based on the condition, imaging results, intravascular ultrasound and pressure guidewire measurement, etc.
