The development of cardiac stent intervention has brought life blood flowing again to the life-channel which was on the verge of blockage, bringing new life to many patients with coronary heart disease Many patients with coronary heart disease think that the more expensive the heart stent is, the better it is, in fact, it is not. “The more expensive the stent, the better” is the common view of many patients or their families who need stent intervention. Most Chinese people promote the theory of “high price and high quality” when it comes to medical treatment, which is actually a misunderstanding. Individualized treatment is the key to medical care. Drug-eluting stents are more expensive, but they are not suitable for all patients with coronary artery disease. For example, it is not suitable for elderly patients who have enlarged blood vessels or are over 80 years old, and these patients are more suitable for bare metal stents. Because patients must take anti-platelet drugs for life after putting in drug-eluting stents, which may lead to brain bleeding or stroke in patients. In contrast, bare stents are not only cheaper and safer, but also require only 4 weeks of antiplatelet medication after the procedure to return to normal. In addition, many patients often have the mentality that heart stents must be put in imported ones to be “secure”. In fact, this is a misconception. According to the clinical follow-up, the effectiveness and safety of domestic stents are similar to those of imported stents. Whether it is stent intervention or surgical bypass surgery, these treatments are only “treating the symptoms but not the root cause”, not a permanent solution! They are like a “plumbing repairman”, by “clearing” or “bridging”, temporarily unclogging the blood vessels, restoring the blood supply and improving the patient’s symptoms. If the patient does not pay attention to change the bad habits after the surgery, the pipeline will still be blocked and the heart will have new problems. Many people, due to the lack of understanding of coronary heart disease and the importance of its high recurrence rate, even though they are already under treatment, often stop taking the medication without permission after a period of treatment when they feel good about themselves, resulting in acute recurrence. Coronary heart disease is a progressive chronic disease with high recurrence disease characteristics, once recurrence, will bring greater threat to health and even life, serious consequences can occur.
