1.What are coronary arteries? Coronary arteries are arteries that supply blood to the heart, referred to as “coronary arteries”. Heart disease caused by coronary artery disease is called “coronary heart disease”. The coronary artery is divided into three vessels, namely the right coronary artery, the anterior descending branch of the coronary artery, and the circumflex branch of the coronary artery. 2.Why is coronary angiography the gold standard for the diagnosis of coronary heart disease? Chest tightness and chest pain after exertion is the main symptom of coronary heart disease, but not all chest tightness and chest pain are coronary heart disease. When angina is not onset, general ECG is not significant to diagnose coronary heart disease; when angina is onset, most of the time the patient is not in the hospital and cannot do ECG. Only coronary angiography can find out whether the coronary arteries are narrowed and the degree of coronary artery narrowing. 3.To what extent can coronary artery stenosis be diagnosed as coronary artery disease? Generally speaking, coronary artery stenosis of R50% can be diagnosed as coronary artery disease, and the degree of coronary artery stenosis between 50% and 70% is considered as critical lesion. A coronary stenosis of R70% is a severe stenosis of the coronary arteries. 4.What stages of coronary artery stenosis can TCM intervene to treat? First, TCM can intervene in patients with coronary stenosis of about 50%. Secondly, Chinese medicine can also be very effective in treating critical lesions. Patients who have coronary CT or coronary angiography show that their stenosis is 50% to 70%, although they do not need to put stents, but in order to relieve symptoms and prevent further development, drug intervention is necessary. Third, prevention or treatment of coronary restenosis. Some patients with coronary stents may experience restenosis in the stent for various reasons. Chinese herbal medicine can play two roles in this case: firstly, after stenting, taking Chinese herbal medicine can prevent restenosis and reduce the adverse effects of drugs; secondly, treatment of restenosis with Chinese herbal medicine can relieve symptoms and unblock blood vessels. 5.What are the advantages of Chinese herbal medicine in treating coronary artery stenosis? The relief of symptoms is obvious. We have observed in the clinic for many years and found that Chinese herbal medicine has a significant effect on relieving symptoms such as chest tightness and chest pain in patients with coronary heart disease. Strong targeting and individualized medication. Every clinical prescription is prescribed for different patients with the right medicine. For example, the same coronary stenosis, but people have fat and thin, diet has strength and weakness, the patient’s tongue and pulse are also different, the same coronary stenosis, the prescribed Chinese medicine prescription is different. In Chinese medicine, it is called different treatment for the same disease, which varies from person to person. Therefore, the prescription of Chinese medicine for coronary artery stenosis is very targeted. Adverse reactions are small or absent. 6.What is the cause of coronary stenosis? There are many causes of coronary stenosis, such as hypertension, hyperlipidemia, diabetes, etc. Age factor is also an important cause of coronary artery stenosis. There are also smoking, poor lifestyle, etc. 7.Why should we check the carotid artery vessels? Ultrasound examination of carotid vessels can detect the presence of plaque in the artery at an early stage for early treatment. Carotid arteries are in the superficial layer and easy to check to find lesions. Vascular problems are a problem of the whole body, but some vessels are deeper and inconvenient to examine, while the carotid artery is a window through which lesions can be detected early. 8.What are the methods to eliminate plaque? Acute myocardial infarction is all due to the rupture of plaque, which forms a blood clot and blocks the blood vessel. Angina pectoris also occurs because of the plaque in the blood vessel, which narrows the coronary vessels and reduces the blood supply to the coronary arteries, which cannot meet the needs of the heart. Therefore, stabilization and elimination of plaque is an important part of the treatment of coronary heart disease. For this, western medicine mainly uses lipid-lowering drugs such as various statins simvastatin, atorvastatin, etc. Chinese medicine is also very effective in eliminating plaque and stabilizing plaque, mainly using blood invigorating and siltation class, such as Danshen, angelica, Chuanxiong, red peony, safflower, peach kernel, etc.; phlegm dispelling medicine such as Panax quinquefolium, Guahua, Chenpi, Houpu, Citrus aurantium, etc.; Yang tonifying and warming medicine such as Radix et Rhizoma, Gui Zhi, Cinnamon, Hsiang Xin, Gan Jiang, etc.; Spleen strengthening and Qi tonifying class such as Astragalus, Radix Codonopsis, Atractylodes, Poria, Huang Jing, etc. Chinese medicine treatment for coronary heart disease is a holistic regulation, focusing on the whole body, starting from nourishing the spleen and stomach, tonifying the kidneys and warming the yang, draining the liver and regulating the qi, etc., with few side effects and definite curative effects. 9.What are the Chinese medicines for treating coronary stenosis? In recent years, our heart center has conducted in-depth research on coronary artery stenosis, and has achieved better results in treating coronary artery stenosis by using Chinese patent medicines and Chinese herbal tonics. Some of those who do not have time to take Chinese herbal soup can also use Chinese herbal granules, which can be taken by brewing, and it is convenient to carry and take. Chinese patent medicines, herbal tonics and herbal granules are all very effective in treating coronary stenosis.
