As a foreign body implanted in a blood vessel, even if the surgery is successful, patients will always think about the stent inside their body for fear that it will be damaged and become dangerous! What is the “life span” of an intravascular stent? Heart stents were introduced in the 1980s and have saved the lives of countless heart patients until now. Because once implanted in the blood vessel, it will be gradually surrounded by coverage because of the growth of the endothelium of the blood vessel, and at this time, in fact, the stent and the blood vessel can be considered as one, and simply considering from the stent, its life span is much higher than the life span, in a sense, the stent does not exist the concept of life span, it is not like other medical devices, there is wear and tear or energy, once the wear and tear is larger and the energy disappears, it needs to be Once implanted, it does not need to be removed. How long does a stent keep a blood vessel “open”? I think this is the answer to the question. The life span of a stent, as often referred to by cardiologists, also refers to the duration of vessel patency. If the patient does not stop smoking and drinking, does not exercise in moderation, does not take medication regularly, and does not regulate his or her diet, it is likely that the patient will have a secondary stenosis within a short period of time and will need to continue the stenting procedure. On the contrary, if the patient strictly follows the medical advice to take medication regularly and improve the living and eating habits, then the time of secondary stenosis will be pushed backwards, which is why the fate of the same patients as post-stenting patients is completely different, one has secondary stenosis after a few months and one has secondary stenosis after several years. So how should post-stenting patients extend their “stent life”? 1.Regular medication is the foundation The basic drugs are aspirin, clopidogrel and statin, the former is anti-platelet coagulation, the latter is lipid regulation to stabilize plaque, and also need to increase or decrease drugs according to related diseases, such as hypertension, diabetes, cardiac arrhythmia, etc. 2.Habit change is the process Healthy diet and moderate exercise are necessary and the least costly way of treatment. Alcohol and tobacco are negative products, at least for the patients, so they must be quit. 3, regular review is the focus Timely review is the most effective weapon to detect physical abnormalities, and strive to find the first signs of stenosis in the stent at an early stage, and because of the long-term use of aspirin, you need to pay attention to the presence of side effects of drugs such as darkening of the stool.
