Earlier, a new study was published in the New England Journal of Medicine, an authoritative foreign clinical medical journal, pointing out that 1/5 of Americans undergoing coronary angiography were unnecessary. Crown implantation is a necessary test for heart stents in heart disease patients, but in fact, it is the heart stent that is more serious than its abuse.
A slender metal cage, when it enters the blood vessel can open the blood vessel that is about to be blocked, this is the stent.
Stents are closely linked to the treatment of coronary heart disease. When the coronary arteries that supply blood and nutrients to the heart appear hardened, narrowed, and blood is not smooth, it can cause angina, myocardial infarction, and even life-threatening. Stent surgery can use vascular puncture technology to put the heart stent into the coronary artery, quickly open the narrow occluded blood vessels, so that blood flow can be restored, so that the affected organs continue to work normally.
Cardiac stents have the advantages of good effect, small trauma, fast recovery, and repeated use, so many patients with coronary disease mistakenly believe that cardiac stents are necessary means to treat diseases.
However, such a "life-saving thing" is now being abused.
Hu Dayi, director of cardiovascular diseases at the Chinese Medical Association, believes that a large number of patients who do not need interventional therapy or cannot benefit from interventional treatment are being stented.
In the opening journal study, it was mentioned that nearly half of the people in the United States who should not have been placed in the heart stent were stented; in China, the problem of stent abuse is no more optimistic than in the United States. In China, many patients have been given 5-10 stents, which is obviously over-medical.
Some experts believe that the reason for abuse is that on the one hand, some hospitals regard stents as an economic growth point and a "cash cow", and doctors also attach great importance to the economic benefits brought by stents; another reason is that doctors are overly obsessed with technology. Existential medical students neglect a comprehensive analysis of a patient's condition in pursuit of a more refined field.
The abuse of stents is also related to the patient's cognitive inadequacy. Many patients think that taking medicine and injections is too troublesome. Putting a stent in the body can be done once and for all. Dr. Chen Ximing of the Third Affiliated Hospital of Guangzhou Medical University said that stent implant surgery needs to be strictly evaluated, even if it is suitable for stent implantation, it is not "once and for all" after surgery, and it is also necessary to adhere to anti-platelet aggregation treatment, strict control of blood glucose and blood pressure to prevent recurrence.
The placement of stents is actually a means of first aid, which cannot completely cure coronary heart disease and myocardial infarction, but only assist patients to temporarily unblock blood vessels. The bracket is a foreign body in the body, like a wire cage in the canal, if it is a plastic bag, a branch, it is easier to be blocked. After surgery, patients continue to smoke and do not take medicine on time, which can also lead to a recurrence of the disease or the appearance of new lesions.
Chen Ximing reminded that patients implanted with stents cannot sit back and relax, or they should adhere to anti-platelet aggregation treatment; strictly control blood sugar and blood pressure; maintain a good daily routine and rest, emphasize smoking and alcohol cessation; if chest tightness and chest pain occur, they should go to the hospital for review in time.
Cardiac stents are not the only means of treatment, the most important stents should be installed in patients with acute myocardial infarction. Most of these patients have severe blood vessel stenosis, and coronary artery blockages generally > 90%. At this time, the stent is loaded, which is like killing a blood path, helping to open up the blood vessels, which can save lives.
In addition, there are some patients who look like the blood vessels are not so badly blocked, but the plaque is very unstable, and it is easy to rupture and cause blood clots to accumulate, so even if the blood vessels are narrowed < 70%, they must be stented.
Clinically, there are many cases of people who have not lived long after being stented to the heart. Many people are worried that after putting in a heart stent, it will shorten their life. In fact, most people do not affect their natural life after doing the stent, and even extend their life to a certain extent. For patients due to severe stenosis of blood vessels, drugs can not be solved, cardiac stents are undoubtedly the "last straw".
But stent surgery is surgery after all, and since it is surgery, there are risks. Especially acute myocardial infarction, which is a major disease, myocardial necrosis too much, heart failure is serious, shock occurs, if the stent, it may also be saved, no stent will undoubtedly die. Stents are also a foreign body, and in a very small number of people, rejection will also occur, and acute thrombosis will occur, causing death.
Cardiac stents are not a life-saving elixir, it is just a treatment that can improve the quality of life for most patients and prolong the lives of most patients with myocardial infarction. But it is not a cure, or it should not be "deified". #The truth is coming ##39健康超能团 #
