Old Zhang’s first stent Old Zhang had a sudden heart attack one night and was rushed to the hospital by ambulance The doctor gave him a coronary angiogram and found that the two coronary arteries had different degrees of stenosis, so two stents were implanted After the surgery, the doctor advised Old Zhang to improve his lifestyle and take long-term medication. But Zhang felt that he had already done the stent surgery, so he did not take the doctor’s advice to heart and stopped the medication without permission. After the operation, he asked the doctor: “Doctor, you said that I have already done stenting, and the blood vessel has been opened, why will myocardial infarction happen again? The doctor gave Zhang an image example: stent surgery is equivalent to widening the river at the blockage and temporarily clearing the sediment, however, without controlling the source of the problem, there will still be sediment entering the river and causing blockage again. Stents are not a “talisman” for patients with myocardial infarction 1. it is likely that there are multiple stenoses, and a stent can usually open only one stenosis 2. the opened vessel may be stenosed again 3. the accompanying cardiovascular risk factors contribute to the creation of new atherosclerosis or aggravate the existing atherosclerosis Therefore, patients with myocardial infarction cannot Therefore, patients with myocardial infarction cannot consider stents as their “talisman” and think that they can rest easy once they have stent surgery. After stent implantation, patients with coronary artery disease should still adhere to long-term secondary prevention medication according to the doctor’s requirements, and improve poor lifestyle, low salt and low fat diet, strengthen exercise, quit smoking and limit alcohol, avoid excessive stress and emotional tension, control many risk factors such as blood pressure, blood lipids and blood sugar, and regularly follow up with the hospital to monitor the indicators, so as to maximize the protection of heart and blood vessels. In this way, we can protect our heart and blood vessels to the greatest extent possible, so that the stent can be kept open and bring long-term benefits to ourselves.
