First, to clarify the differential diagnosis, the combination of diagnosis and evidence Modern medicine so-called “coronary heart disease”, “angina pectoris” and Chinese medicine disease name “chest paralysis”, “heart pain The terms “coronary artery disease” and “angina pectoris” are the same as the Chinese medical terms “chest paralysis” and “heart pain”, but they do not exactly match. Angina refers only to a disease of coronary atherosclerotic heart disease in which pain in the precordial region is a diagnostic clue, among which there are also palpitations, chest tightness, breath-holding, shortness of breath after activity, weakness, etc. as the main manifestation. In contrast, “chest paralysis” refers to all diseases that are mainly associated with chest pain, including various circulatory system pathologies of the heart and chest vessels, respiratory system disorders, stomach and esophageal digestive system, chest muscles, ribs, thoracic joints, nerves, etc., which can involve a group of clinical symptoms of multiple systems, organs and tissues. Modern clinical practice requires a combination of Chinese and Western medicine, combining disease identification with evidence identification, and using differential diagnosis knowledge to try to clarify the location and pathological nature of the lesion. If there is localized pressure pain in the thoracic rib joints, it is considered to be Taizi’s disease (costochondritis); if angina attacks after a full meal or in the recumbent position, attention should be paid to exclude esophageal hiatal hernia, reflux esophagitis or biliary heart syndrome, etc.; the duration of chest pain and drug remission are also important to inquire, and the attack that stops in a few seconds is mostly intercostal Neuralgia, and those who do not relieve for more than half an hour may be functional disorders such as cardiac neurosis, or critical illnesses such as myocardial infarction and rupture of aneurysm; therefore, the necessary physical and chemical examinations and auxiliary examinations such as electrocardiogram and X-ray are indispensable in the treatment process. Therefore, the nine prescriptions listed in Jin Kui Yao Yao – “The Treatment of the Pulse of Chest Palsy and Heartache and Short-Qi Disease”, such as Gua Gua Bai Bai Agent, can be used for angina pectoris, bronchitis, emphysema, etc. in cases of upper jiao yang deficiency and phlegm and saliva congestion in the chest; while Ren Shen Tang, Fu Ling Almond Glycyrrhiza Soup, Orange and Citrus Aurantium Ginger Soup can significantly improve the symptoms of angina pectoris, gastritis, esophagitis, etc. in cases of deficiency of middle yang, or internal stagnation of water-drink, or qi stagnation and qi rebellion. If a patient with diagnosed angina pectoris is combined with symptoms of the digestive system, it is more effective to combine the above meridian formulae with the prescriptions for the dominant pathogenic mechanism; there are also Coix Seeds and Pills and Wutou Red Stone Pills for variant angina pectoris, myocardial infarction, bradycardia and cardiogenic shock, etc., which can be applied on the basis of evidence. Only on the basis of clear differential diagnosis, the same treatment for different diseases can be better implemented. Modern medicine believes that angina pectoris is a metabolic disorder caused by multiple risk factors such as imbalance of lipid metabolism, blood clotting mechanism and abnormal secretion of vasoactive substances due to neuroendocrine disorders, which is mainly influenced by genetics and lifestyle. According to Mr. Shi, the dominant TCM pathogenesis is Qi and Yin deficiency as the root cause and phlegm and stagnation as the symptoms. The treatment method is to benefit Qi and nourish Yin, invigorate blood circulation and remove phlegm, which is suitable for most patients with angina pectoris. For patients with Qi stagnation and blood stasis, Yin-cold stagnation, cold and phlegm congestion, and yin-yang disharmony as the main symptoms, we treat them according to the changes of the disease mechanism. Modern medicine classifies angina pectoris into exertional angina pectoris and spontaneous angina pectoris. Among them, the exertional type is induced after activity and aggravated by exertion, and the Chinese medicine identifies the presence of deficiency. The spontaneous type of variant angina is often accompanied by coronary spasm, which is characterized by frequent occurrence at night, and most of the evidence is related to Yang deficiency and cold condensation. For example, for patients with angina pectoris with Yang deficiency and cold clotting, Mr. Shi gave intravenous allicin injection for better pain relief; for patients with angina pectoris with Yin deficiency and heat, he gave pulsatilla injection; for patients with deficiency of Qi and Yin and deficiency of cardiac function, he used raw pulse injection; for patients with Yang deficiency and cold limbs and swelling, he used ginseng injection The patient with Yang deficiency, cold limbs and swelling can use Ginseng Injection. There are many varieties of clinical herbal intravenous, it is necessary to distinguish the cold, heat, flux and tonic nature of the drugs and to target them.
