What is coronary heart disease? Coronary heart disease is a heart disease caused by atheromatous plaque proliferation or combined thrombosis in the coronary arteries, resulting in insufficient blood supply to the coronary arteries, myocardial ischemia or infarction. The clinical manifestations of coronary heart disease include angina pectoris, myocardial infarction, arrhythmia, heart failure and even cardiac arrest, depending on the condition of the vascular lesion. The first symptom of coronary heart disease is most commonly myocardial infarction, or is a life-threatening situation such as cardiac arrest, which often cannot be accurately predicted, while patients with angina symptoms, because the symptoms often last only a short time, not attack like normal people, can not attract sufficient attention, and when the symptoms worsen coronary lesions have been very serious, the price paid is very large, another part of patients with symptoms are not The other part of the patient’s symptoms are not typical, and it is difficult to capture the changes in the ECG at the onset, often to doctors or the patient’s own experience to take treatment, or repeatedly do some tests of little significance, such as CT, not to mention wasting a lot of money, either delayed the disease, or misdiagnosis and misdiagnosis, let people regret. How to treat coronary heart disease? First of all, we need to expand the coronary arteries of the heart to increase the blood supply to the heart muscle cells. Commonly used drugs are nitroglycerin, and also the use of often said to reduce blood viscosity drugs, inhibit platelet aggregation. Commonly used are aspirin, clopidogrel (Bolivar); in the case of high blood lipid application of some lipid-lowering drugs. If drug treatment is not effective, we should consider surgical treatment: interventional treatment. What is stent therapy for coronary heart disease? As we all know, hypertension, diabetes, hyperlipidemia and smoking can lead to atherosclerosis. Just like the rusty walls of water pipes, cholesterol and other substances are deposited in the walls of the coronary arteries of the heart, causing blockage of blood flow to the heart and causing coronary heart disease. Coronary heart disease is the cause of angina pectoris, myocardial infarction, sudden death and other serious conditions that endanger the lives of patients. At present, the three main means of preventing and treating coronary heart disease are medication, interventional treatment and coronary artery bypass surgery, among which interventional treatment is favored for its small trauma and significant effect. The principle of interventional treatment for coronary artery disease is to put metal stents in the lumen of blood vessels, which is the same as unblocking a sewer pipe. Stents prevent localized vascular “collapse” and open up blood flow to the heart. The stents are divided into various materials depending on the material, and the ones widely used in clinical practice are mostly made of special stainless steel, which may be mixed with different rare metals; of course, there are also other materials, such as magnesium alloy stents under study, which are characterized by being absorbed by the body after a period of time. Can the stent alone cure coronary heart disease? No, it is not. A heart stent is only a temporary solution, it does not cure coronary heart disease. The coronary artery is not just a blood vessel, it has branches, and there are smaller branches underneath the branches. Stenting only improves and unblocks a small section of the most severely stenosed “coronary artery”, it is not a fundamental treatment for the cause of coronary artery disease, most patients still have hidden problems, so if we do not pay attention to control the potential risk factors, other parts of the blood vessel may still be blocked. To truly control the progression of coronary heart disease, antiplatelet therapy is necessary. At the same time, it is important to control hypertension, hyperlipidemia, and hyperglycemia, because these three high conditions can damage the inner walls of blood vessels, destroy their interiors, cause atherosclerosis, and eventually form blood clots. Therefore, patients with hypertension, hyperlipidemia and diabetes need to insist on taking antihypertensive drugs, lipid-lowering drugs and glucose-lowering drugs at the same time after stenting. Why do I need antiplatelet therapy after stent placement? A 65-year-old mother He has suffered from coronary heart disease for many years and had a heart stent placed 6 months ago. Not long ago, she suddenly developed chest pain and was diagnosed with “myocardial infarction” after examination, and the stent was completely blocked by blood clots. The stent placement was performed again to save her life. Why did this happen? It turns out that after the stent was placed, all the symptoms disappeared and she felt “the same as when she wasn’t sick”, so she relaxed her medication and simply stopped taking aspirin and clopidogrel (Bolivar) in recent weeks, which resulted in myocardial infarction. In fact, after drug stenting, there is a possibility of thrombus formation in the stent for a longer period of time, and antiplatelet medication can prevent thrombus formation to the maximum extent possible to ensure that the heart vessels remain open for a long time. Once a patient discontinues antiplatelet therapy early, the risk of reocclusion increases dramatically, and once an in-stent thrombus is formed, it can be life-threatening. Antiplatelet therapy is currently recommended to be adhered to for at least 12 months to truly minimize recurrence.
