Introduction: When it comes to cardiac stents, you may not be unfamiliar, it first appeared in the 1980s, is a medical device often used in heart surgery, also known as coronary stents, cardiac stents can effectively prevent coronary heart disease, prevent the emergence of myocardial infarction, and are widely used in clinical practice.
However, in recent years, there have been some controversies about cardiac stent surgery, some people feel that this is a life-saving operation, and some people think that cardiac stents are overtreatment, so is cardiac stent surgery good or bad? I'll take a closer look at it today.
Under what circumstances do I need a cardiac stent?
Found that the heart artery blood vessels, stenosis is more than 75% of the stenosis, there is chest tightness, chest pain, etc., myocardial ischemia symptoms, can consider implantation stent, coronary heart disease is caused by multiple causes, coronary artery stenosis or blockage caused by myocardial ischemia, hypoxia or myocardial necrosis of the heart disease.
Coronary angiography is a common and effective method for diagnosing coronary heart disease, is a safe and reliable invasive diagnostic technique, and is considered the gold standard for diagnosing coronary heart disease.
Coronary angiography can find stenosis of visceral vessels, there are the following possibilities, coronary arteries, less than 50% of stenosis diagnosis of coronary atherosclerosis, coronary stenosis of more than 50%, can be diagnosed as coronary heart disease, stenosis more than 75% of the severe stenosis.
According to the actual situation, decide whether to install stents, whether conservative drug treatment can eliminate stenosis, at present, drugs can only control the progression of stenosis, there is no way to completely reverse stenosis.
How many more years can I live after installing a cardiac stent?
Because the patient itself if the heart implant stent, obviously coronary artery vascular severe stenosis, the reason to do cardiac implant stent surgery, the purpose is to prolong the life of people, if the coronary artery blood vessel severe stenosis, do not do treatment or simply apply drugs, then very uninsurable.
Patients may develop acute myocardial infarction at any time, and after the occurrence of acute myocardial infarction, patients may lose their lives, because there are many patients with acute myocardial infarction who may immediately have acute left heart failure, malignant arrhythmias, and even some directly lead to the death of patients.
Therefore, the purpose of doing cardiac stents is to prevent the occurrence of acute myocardial infarction, that is, to prolong the life of patients, and cardiac stents will not affect people's life in the future.
However, because of the coronary heart disease itself, even if it is implanted with a cardiac stent, it will not be able to completely solve the problem, and the patient still has the possibility of continuing to develop, and it is possible that the stent will be narrowed again, so this situation is also life-threatening.
Once a heart stent is implanted, do you have to take a lifetime of medicine?
After doing the stent, because it belongs to coronary heart disease, it is necessary to carry out the second-level treatment of coronary heart disease for life, not related to the stent, but related to the disease of coronary heart disease.
In addition, after stent implantation, you should take anticoagulant drugs for the first half of the year or one year to avoid thrombosis in the stent, which can be gradually reduced or discontinued, but for the treatment of aspirin and statin, it is basically a lifelong drug treatment.
In addition, after the implantation of stents, patients with diseased vascular treatment should also pay attention to low-fat diet and moderate exercise, because the place of narrow lesions is prone to re-emergence of problems, so every four years or so, coronary ct or coronary angiography should be reviewed to determine whether there are lesions of other blood vessels.
For coronary heart disease, this implanted stent is only to deal with the narrowest blood vessels, the most serious place, and the treatment and prevention of the disease also need to rely on drugs and the management of their own lifestyle.
Write at the end:
After the cardiac stent surgery can effectively improve the quality of life of patients, everyone is more familiar with academician Zhong Nanshan, once also carried out cardiac stent surgery, such as although he is more than eighty years old, but the body is still healthy, during the epidemic period, always adhere to the front line of the fight against the epidemic, so everyone should comprehensively and correctly look at this operation.
