How can I put it, purely in terms of number, it is not a lot, because there are people who put 4, 5, 6 and 7 stents. But in terms of lesions, if you need to put in 3 stents, it means that the coronary lesions are still serious.

The blood supply of the heart mainly depends on the coronary arteries, which have several branches, each of which will have tiny branches, but when the coronary arteries are narrowed due to atherosclerosis, the blood supply to the heart will naturally be affected, which is very easy to understand. We compare the heart to a city, then the coronary arteries are the highway to the city, but there are obstacles on the highway or need to repair the road, the highway will become narrower, such as three lanes into two lanes, if there is a car accident in the middle of the road, it may only allow one lane to pass, if the accident is very serious, this access is blocked, then the flow of traffic will be cut off, resulting in traffic congestion.

The same is true for the heart. When the coronary arteries become atherosclerotic, they narrow, and once narrowed, the blood supply is affected (the road is not clear), and if the narrowing is so severe that a thrombus forms and completely blocks it, then the distal end becomes completely ischemic because the blood simply can't get through; it's just like a highway being completely truncated, as mentioned above.

If the heart is ischemic, it will lack of oxygen, the heart muscle may need blood and oxygen ah, once the lack of this thing, certainly not good, the heart muscle will be ischemic necrosis, resulting in myocardial infarction. This is the basis for the development of coronary heart disease.

And the role of the stent, it's easy to understand, is to hold it up in a narrow place, to hold it wide, to make way for the blood to continue to travel unimpeded, to carry blood and oxygen far and wide, to supply the heart muscle with food and drink.

See, this is the coronary artery with the stent in place:

How is the stent put in? It is very simple, because the stent is relatively small at the beginning, you can first come in from a blood vessel outside the body, because the blood vessels are all connected together, all the time connected to the channel coronary artery, and then open up the stent after going deeper into the coronary artery, as shown in the picture above.

Going back, let's say 3 stents is not too many or not? Not too many in terms of sheer numbers, because 45678 have been put in, and some people may have put in a dozen stents, which suggests severe coronary artery disease, with multiple roots and multiple lesions. At this point it may be more appropriate to choose coronary artery bypass surgery, not necessarily stents.

Coronary arteries with such severe lesions are not permanent after stent placement, and must be treated with appropriate medications, such as antiplatelet aggregation, treatment of hypertension, hyperlipidemia, hyperglycemia, and other therapies, in order to make the coronary artery condition better and to reduce the occurrence of coronary artery accidents.

The number of brackets can be placed more than one according to the needs of the condition, there is no strict limit.

Coronary stenting, also commonly known as "stenting", has the effect of unblocking blocked coronary vessels and has been an effective means of treating coronary artery stenosis in recent decades. In the past 20 years, this term is no longer unfamiliar to the general public. According to Taiwan media reports, Lee Teng-hui had 11 heart stents, or some say 13, put in while undergoing cardiac treatment. So the 3 stents you mentioned are not too many, and of course cases where more than 10 stents are put in are relatively rare, because the more stents are put in, the chances of restenosis of the blood vessels will also increase significantly.

Cardiac stent implantation, it is only a part of the treatment of coronary artery disease, where a stent is placed only to solve the lesion of which blood vessel, while the lesion of other blood vessels is not solved, so it is not a one-off. The placement of 3 stents indicates that your coronary artery condition is severe:

1, adhere to regular medication, "medicine can not be stopped", take it every day;

2. Regularly go to the hospital for follow-up to check how the drug efficacy is, to check whether the blood lipids, blood glucose and blood pressure are up to the standard, and to check whether there are any adverse drug reactions (regular evaluation of liver and kidney functions);

3. Low-salt, low-fat diet and appropriate exercise;

4, maintain a relaxed and happy mood, avoid emotional excitement and excessive fatigue.

　　Coronary artery stenosis can cause myocardial infarction and seriously affect the function of the heart. With the development of interventional technology, coronary artery stenosis can be treated with stents, and cardiac stenting has become an effective means of treating coronary artery stenosis in recent decades. According to Taiwan media reports, Lee Teng-hui in the heart treatment put 11 heart stents, compared to the heart put 3 stents is not too much.

　　However, if three heart stents are implanted because of coronary stenosis, it means that the patient's coronary stenosis is already relatively severe, and the general principle of stenting is to put the stent wherever the stenosis is. If three stents are put in, there may be three narrowed areas in the coronary vessels, which seriously affects the blood circulation of the heart. There are two types of cardiac stents, domestic and imported, and generally speaking, domestic stents are included in medical insurance, while imported stents are generally covered by out-of-pocket expenses.

　　In fact, if more stents are put in, later complications or side effects will be more obvious. In particular, the formation of secondary stenosis, the production of blood clots and so on will be more serious. After the implantation of cardiac stents, blood clots are likely to occur inside the stent, the two stents connecting parts, the edge of the stent, and so on. Therefore, if you have undergone cardiac stenting, it is important to pay attention to the following aspects:

　　First, adhere to regular medication, use anticoagulant drugs according to the doctor's requirements for at least six months after the operation, "the medicine can not be stopped", take it every day to prevent the occurrence of blood clots.

　　Secondly, regular follow-up in the hospital to check the efficacy of the drugs, check whether the blood lipids, blood glucose, blood pressure, etc. are up to standard, check whether there are any adverse reactions to the drugs, and regularly evaluate the liver and kidney functions, coagulation routines, etc. for three months.

　　Thirdly, coronary heart disease is often associated with high blood pressure and high blood lipids. It is crucial to have a reasonable dietary structure after surgery, and it must be a low-salt and low-fat diet, along with medication to control blood pressure and blood lipids.

　　Fourth, we must maintain a relaxed and happy mood, avoid emotional excitement and excessive fatigue, maintain a regular routine, do not stay up late.

The number is really not much, but putting three stents proves that at least three parts of the body are seriously diseased, so don't relax just because three is not much, in terms of the disease, one is more than one. We suggest that you take strict preventive measures, including a diet low in salt, low in oil, low in sugar, ensuring a variety of food, ensuring adequate absorption of nutrients, maintaining a good daily routine, quitting smoking and restricting alcohol (must quit smoking, must quit smoking, must quit smoking, must quit smoking, I must say it three times. 三次） 还有适量运动 远离高噪音二手烟等高污染不健康场所 等等 这样多管齐下 才能对病情的康复做到事半功倍 祝健康

Thanks for the invitation.

My mother had 8 heart stents and now she can only do medication.
