According to Chinese medicine, the main causes of this disease are old age and body failure, deficiency of Yang energy, over-eating of fat and sweet, invasion of cold evil, and internal injury of the seven emotions. As a result of the above causes, blood stasis and phlegm obstruct the heart arteries. This disease is the evidence of deficiency of the origin and the symptoms of the symptoms. The deficiency of the origin includes deficiency of qi, blood and yin, with qi deficiency and yang deficiency being the main causes. The symptoms include blood stasis, phlegm, cold condensation, and qi stagnation, with blood stasis and phlegm predominating. The basis of pathogenesis is the original deficiency, and the symptoms are the conditions of pathogenesis. The basic pathogenesis of the disease is that the heart veins are blocked, the heart is not nourished, and if it does not pass, the pain develops as chest paralysis and heart pain. The disease is located in the heart, but its pathogenesis is also related to the strength and weakness of the kidney, spleen and liver organs. 1, old age and physical weakness, lack of qi and blood Old age and physical weakness or after a prolonged illness, the heart and spleen are both deficient, the heart is deficient in qi, the drum is not strong, easy to cause qi stagnation and blood stasis. The spleen is not healthy, dampness becomes phlegm, the evil of phlegm and turbidity invades the heart and chest, blocking the heart and yang, the chest and yang are not spread, the qi is not smooth, and the heart is blocked. 2, heart and kidney Yang deficiency, Yin cold phlegm drink Yang Qi deficiency, can not encourage the heart Yang, heart Yang is not revitalized, blood vessels are not warmed, paralysis and blockage, resulting in heart pain; heart and kidney Yang deficiency Yin cold phlegm drink evil take advantage of Yang position, blocking the heart veins, resulting in heart pain. 3, over-eating fat and sweet, damage the spleen and stomach Eating fat and sweet products with abandon is easy to damage the spleen and stomach over time, the health and transportation is not in order, the diet can not transform qi and blood, gathering dampness into phlegm, phlegm blocked inside, the qi is not smooth, the heart arteries are paralyzed, so heart pain occurs. 4.Cold invasion, loss of chest and yang exhibition Cold coagulates the heart and blood, which leads to abnormal operation of the Ying and Blood, resulting in the development of this disease; cold is a yin evil, and the heart and yang are already weak, so if the cold is felt, the yin and cold are even stronger, making it easy for heart pain. 5.Seven internal injuries, Qi stagnation in the heart and chest Seven internal injuries, depression, Qi stagnation in the upper jiao, chest Yang loss of exhibition, blood vessels and disharmony, so the chest pain, good tai breath.
