In the 1980s, a heart stent was invented in the history of medicine, which was mainly used to unblock arterial blood vessels. The original stent was a metal structure, and later developed into a drug-coated Layer, followed by the research of bioabsorbable technology.
After China’s accession to the WTO, reforms have been strengthened significantly, promoting the continuous price reduction of medical device products,< strong>my country’s heart stent has also been reduced from the initial 40,000 yuan to 13,000 yuan, and the last round of price reductions has reached 400-700 yuan. There are many benefits.
However, there has always been a lot of controversy about heart stents on the Internet. Some people say that heart stents have long been eliminated abroad, is this true?
01
Is the heart stent a product of foreign elimination?
According to the 2019 China Cardiovascular Health and Disease Report,Nearly 1 million people receive stent treatment in my country every year , As the incidence of coronary heart disease has increased over the past few years, the application of cardiac stents has become more and more common.
In addition, there are relevant data showing that between 2013 and 2017, 1,752 hospitals in the United States have been exposed to heart stent surgery, with a growth rate of 15.8 %, 550,000 cases in 2013 rose to 638,000 cases in 2017.
There are 1,108 hospitals in Japan who have been exposed to heart stent surgery, with a growth rate of 36%, from 180,000 cases in 2013 to 2017 247,000 cases.
It can be seen from the above data that whether it is China, the United States or Japan in the treatment of coronary heart disease, especially acute myocardial infarction, Heart stents are still the main treatment method, so heart stents have not been eliminated, but the lives of countless patients have been saved by heart stents.
02
When should a heart stent be installed?
1. acute myocardial infarction
Acute myocardial infarction is a strong indication, a heart stent must be implanted immediately, Opening the blood vessel at the first time is the direct treatment method to save the myocardium.
2. Refractory angina
If the heart is found to be severely stenotic after angiography and the drug effect is not good, a heart stent should also be installed , there are three large blood vessels in the heart. If the lesion is large and involves more angiography, it is found that more stents need to be installed. The patient may be told that it is not suitable to install stents. At this time, bypass treatment can be used.
If the lesion is less than 75% and the lesion is mild, it is recommended to use drug treatment first, a heart stent needs to be installed, and the diagnosis needs to be based on the patient’s clinical symptoms and the results of coronary angiography.
03
How many years can I live with a heart stent installed? The doctor no longer hides, please tell the family
How many years the patient can live after installing the stent varies from person to person, the patient is Whether to take relevant drugs on time after installing the stent, whether to improve through lifestyle intervention, and the severity of the patient’s current condition will all affect the patient’s prognosis.
It’s not that if you install a heart stent, everything will be fine, because the heart stent is only placed in a relatively serious part of the body, and it’s not enough to improve the condition Will cure the disease, postoperative conditioning is very critical.
Patients have severe stenosis of heart vessels, and the survival and prognosis of patients with stents are longer than those without stents, the patient’s heart and blood vessels are always in a state of severe stenosis, which may lead to myocardial infarction at any time, and may gradually lead to heart failure. After installing the stent, it will help improve the blood flow of the coronary arteries and prevent the recurrence of myocardial infarction.
If the patient maintains a reasonable life after cardiac stenting Habits, taking medicines on time, their later life may be extended to more than 40 years.
04
Do heart stents have a shelf life?
The heart stent is for life and does not need to be replaced. The heart stent is made of metal, such as nickel-titanium alloy or stainless steel, etc. The mesh structure will be embedded in the intima of the blood vessel after stretching the inside of the blood vessel.With time, vascular endothelial cells can completely cover the stent, and the stent and vascular tissue can grow together completely.
But after the heart stent, I did not take the medicine on time, and still did not control it, such as frequent high-salt, high-oil, high-sugar diet If the blood pressure and blood sugar cannot be effectively controlled, the blood vessels will be blocked or narrowed again, and a second heart stent operation is required.
05
How to care after heart stent surgery?
1. Diet adjustment
Maintain a low-salt, low-fat and light diet,eat more fresh fruits and vegetables , ensure adequate drinking water every day, and avoid spicy and smoked food.
2. Emotional conditioning

4、< span>Take the medicine as prescribed by the doctor
After the heart stent, the patient should take anticoagulant medicine , to avoid in-stent restenosis, especially those with metabolic diseases such as hyperglycemia and hyperlipidemia, must take medicine on time.
5. Periodic review
After the heart stent operation One year is the period of high incidence of stenosis, and regular reexamination is required. Generally, coronary artery reexamination is performed every six months and one year after surgery, and electrocardiogram, cardiac color Doppler ultrasound, and blood tests are performed every three months. Usually feel unwell to check at any time.
