Release date: 2016-03-21 "This kind of surgery that is commonly used in China has been eliminated in the 1970s and 1980s. The Chinese have also called high-tech. This surgery is 500-800 dollars abroad." "After this operation, it means There is a time bomb buried in the body, and it will die within 3 minutes after a sudden onset, which is faster than the 12-minute death of a myocardial infarction." "The medicine that I have done for the whole life of this operation is aspirin, you don't die in heart disease." I have to die on this medicine"... Focus 1: The technology that has been eliminated internationally, is the Chinese a treasure?

When the incidence of coronary heart disease increases, people's attention to the heart stent is far more than the question of "abuse" and "profiteering". The reporter sorted out some of the focus issues of the people's attention and interviewed several experts.
According to Zhong Zhimin, director of cardiovascular surgery at the Second People's Hospital of Guangdong Province, the current main treatment for coronary heart disease is heart bypass surgery or cardiac stent surgery. Surgical treatment (bridge bypass) refers to taking a blood vessel from other parts of the patient's own body and then connecting them to the ends of the stenotic or blocked coronary artery, so that the blood flow can be bypassed, so that the ischemic myocardium can be oxygenated and relieved. Myocardial ischemia symptoms. Interventional therapy (stenting) is a kind of cardiac catheter technique. It is through the femoral artery at the base of the thigh or the radial artery on the wrist. The stent or other instruments are placed into the coronary artery through vascular puncture to achieve the purpose of relieving coronary artery stenosis.
Experts such as Zhong Zhimin believe that it is completely misunderstood that this technology has been eliminated abroad. The heart stent saved many patients in the acute phase. For patients with acute myocardial infarction, time is life, the sooner the blood vessels are opened, the better the treatment effect. Inserting the stent to open the blood vessel is the most effective method. This technology is one of the common methods of treating coronary heart disease, and the technology is very mature at home and abroad.
Focus 2: Is the heart stent a "time bomb" buried in the body?
According to Yan Ji, director of the Department of Cardiology, Anhui Provincial Hospital, the technology of cardiac stents is also progressing. The first generation is a balloon-type stent, which is local anesthesia in vitro, and then the catheter is placed into the blood vessel where the stenosis has occurred. However, it was later found in clinical practice that approximately half of the patients were re-occluded at the surgical site between three months and six months after surgery. In the 1990s, a new type of stent was invented, and the proportion of postoperative blockage decreased by 15%-30%. At present, the most commonly used in clinical practice in China is the third-generation stent, which is a drug stent. The stent is attached with a drug to prevent excessive proliferation and calcification of the endothelium of the surgical site. At present, the probability of re-occlusion of the surgical site is only 5%-8. %.
“Now the fourth generation of stents is a biodegradable bioscaffold, and of course the price is more expensive. In short, this technology is constantly improving, clinical side effects are getting smaller and smaller, and the postoperative effect is getting better and better. It is fully affirmed at home and abroad. Technology. The statement that the post will be blocked again in the post is absolutely alarmist," he said.
Focus 3: Isn't death in the stent or death in medicine?
Yan said that it is also a misunderstanding about taking medicine for life. There are three main clinical treatments for coronary heart disease: drugs, stents and heart bypass. Of course, regardless of the stent and bridge, the drugs are used at the same time. Patients with coronary heart disease should of course take medication for life and mediate blood viscosity. Commonly used are five drugs such as aspirin, some are calcium channel blockers, some are thrombolytic drugs, and some are regulating blood lipids. The role of aspirin is mainly used to fight platelets. Even if you don't do the stent, you have to take it for a long time; if you do the bridge, you should eat it. It is said that aspirin is carcinogenic to people who have no medical knowledge at all.
Focus 4: Bridge or bracket, who has the final say?
"Indications have the final say." Zhong Zhimin said. It is reported that the world has an annual increase of 1.7 million "support people". However, the stent is not suitable for all patients with coronary heart disease. In general, for left main lesions, three-vessel disease, multiple, multiple, diffuse lesions or lesions at the main vessel bifurcation, it is recommended that patients use surgical “bridge†surgery. Because these lesions are forced to be placed in the stent, on the one hand, it is prone to problems during surgery, and the patient is prone to life-threatening; on the other hand, there are many diffuse coronary lesions. If the problem is to be completely solved, it is not 2-3 stents. Can solve the problem, the probability of recent restenosis is large. Therefore, patients cannot simply choose treatments from “likes†and must strictly follow surgical indications. Otherwise, not only will not get better treatment, but also bear high costs.
Experts combed the indications and advantages and disadvantages of the two treatments: cardiac bypass surgery for left main disease, three-vessel disease, with cardiac insufficiency, with diabetes, coronary heart disease after myocardial infarction complications; cardiac stent surgery for After coronary angiography, the occlusion of the stenosis was determined, and more than 75% of patients with myocardial infarction and 30-65 years of age often occurred.
The advantage of heart bypass is that it can solve severe coronary artery disease, and the long-term effect is good. The disadvantage is that the operation time is long, the wound is large, and the extracorporeal circulator is used to affect other organs. The advantage of stent surgery is that the operation time is short, minimally invasive, and capable. Repeated placement, but the disadvantage is that there may be vascular restenosis, the probability of requiring reintervention is relatively high.
Focus 5: After surgery, once and for all?
Zhong Zhimin said that surgery mainly plays a role in relieving symptoms and stabilizing the condition. To achieve good results, postoperative care cannot be ignored. In addition to adhering to medication, rest after surgery, you can exercise properly, such as walking, but can not exercise vigorously; scientifically arrange diet, ensure that the right amount of fruits and vegetables and low-fat, high-protein foods; a small amount of drinking, it is best not to drink, must socialize Do not exceed 50 ml per day, smoking is strictly prohibited; postoperative examinations are still needed to facilitate the doctor's timely treatment.
Strictly introduced, many people nowadays have irregular life. Big fish and meat, tobacco and alcohol are unrestrained, which can lead to high blood lipids, decreased blood viscosity, and sometimes cardiovascular blockage, leading to myocardial infarction. The heart stent is not a cure for coronary heart disease once and for all. Because the coronary artery in patients with coronary heart disease has developed lesions, the stent can only rule out the risk of the most dangerous part of the myocardial infarction, but if his cardiovascular disease continues to deteriorate, continue to appear elsewhere, continue to put Bracket.
