When does the patient need to put the heart stent?

Nowadays, with the rapid development of society, people’s living standards are also improving. At the same time, many factors, such as work pressure and life pressure, have accumulated, making people’s health worse and worse. According to the statistics of the World Health Organization, in 2019, about 9.14 million people worldwide died of coronary heart disease, and about 197 million people worldwide suffered from coronary heart disease.

Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, also known as ischemic heart disease. If patients suffer from coronary heart disease, they are very likely to die of angina pectoris and myocardial infarction. Coronary heart disease is a chronic disease, which can not be completely cured by taking medicine, but can only be inhibited by medicine. If the disease is serious and sudden angina pectoris or myocardial infarction occurs, the crisis can only be solved by “heart stent” operation.

01  Under what circumstances is it appropriate for patients to choose heart stents for implantation?

At present, in the diagnosis and treatment standards of coronary heart disease in China, stents can only be implanted if the degree of coronary artery stenosis reaches 75% or more. However, some patients have reached about 60% of the degree of stenosis. Because they are worried about the further development of the disease, they also choose to implant stents.

Many of these patients who implanted stents could not perform physical labor after surgery, which began to spread the saying that “stent surgery will be abandoned if it is completed”. In fact, whether patients with stents can perform physical labor after surgery has nothing to do with stents.

The middle-aged and old people suffering from heart disease have poorer labor force than the ordinary people. The blood flow in the heart and related parts is not smooth, so they naturally feel uncomfortable and their labor ability is not as good as before.

Even if the heart stent implantation surgery is completed, it does not mean complete recovery. The role of the heart stent is to help dredge the blood vessels, alleviate symptoms, stabilize the patient’s condition, and reduce myocardial infarction and sudden death.

02   What is the impact of “heart stent” surgery on patients?

(1)   Favorable impact

Heart stent implantation surgery can improve coronary artery stenosis. In general, when the degree of coronary artery blockage reaches more than 75%, the doctor will recommend patients to carry out heart stent implantation treatment. Use the stent to support the stenotic artery, prevent the artery from retracting again, and dredge the blocked artery, which can effectively improve the problem of artery stenosis.

Heart stent implantation surgery can also improve myocardial blood supply. Generally, patients with myocardial infarction will suffer from angina pectoris, chest pain and other symptoms due to blocked blood circulation. After the intervention of cardiac stent, artery stenosis will be improved and blood circulation will become smooth, which can improve myocardial blood supply.

(2)   Adverse effects:

① In stent thrombosis

Because most stents are metal foreign bodies, blood may be blocked by foreign bodies when flowing through the stents and form thrombus, which is a relatively high-risk complication.

However, at present, the stent technology is relatively advanced, and there is a good way to prevent thrombosis in the stent. The doctor will ask the patients who do the stent to take two antiplatelet and antithrombotic drugs within one year. Through the enhanced antithrombotic treatment of drugs, the risk of thrombosis in the stent can be basically reduced to nearly zero.

② In stent restenosis

After the coronary artery is opened by the stent, although the blood vessel is opened, there are still some pathological changes in the vessel wall, and smooth muscle cells on the vessel may proliferate again, leading to restenosis. However, the drug coated stent is now recommended. There will be drugs on the stent to inhibit the proliferation of smooth muscle, so the risk of in stent restenosis will be greatly reduced.

③ Bleeding symptoms

Although heart stent implantation surgery is relatively mature now, and it is relatively safe to perform such surgery, but after heart stent implantation surgery, you still need to take drugs to resist dissolution. Some patients use antiplatelet drugs for a long time to inhibit the growth of platelet cyclooxygenase, but the drugs in the blood platelet have side effects. Taking such drugs for a long time will prevent our blood from coagulation, so it is not easy to scab and heal the wound, There is often bleeding.

03   What are the types of heart stents? Does the stent have a quality guarantee period?

At present, there is not only one kind of heart stent material, but now it is mainly made of stainless steel, 、nickel titanium alloy, cobalt chromium alloy and other materials.Heart stents are also divided into bare stents and drug coated stents, which can be used to treat coronary heart disease, angina and other diseases.

At present, precision laser processing with its unique advantages, is increasingly used in the medical industry to solve the problems that cannot be overcome by traditional processing and promote the technological innovation and upgrading of heart stent processing. The stent produced by precision laser cutting machine has no burr and smooth incision, high consistency of  rib width, and the quality of  the stent  is guaranteed. For example, the SLC300, BSLC300 and FSLC500 of Changzhou MEN Intelligent Technology Co., Ltd. are commonly used medical stent laser cutting machine.

No matter which of the above materials is used,the stent will be fused with our blood vessel after three months. It will not fall off, so you can rest assured. Stents will not be taken out and replaced after five or ten years of use, as everyone thinks. Without such a statement, it is also an unscientific cognition.

In sum:

Patients suffering from coronary heart disease should know that heart stent implantation surgery is not omnipotent, regardless of whether they have undergone heart stent implantation or not. Even if the operation is completed, it does not mean that the body has recovered. In daily life, we must maintain healthy diet and living habits, insist on taking relevant drugs, and regularly check our physical conditions. Only in this way can we keep healthy for a long time!
