The causes of coronary heart disease can be summarized as improper labor and relaxation, addiction to thick flavors, or internal injuries, but these factors do not make everyone suffer from coronary heart disease, but rather determined by the strength and weakness of the righteousness, the so-called “righteousness within, evil can not dry”. The clinical course of coronary heart disease is long, less than a few months, more than a few decades, recurrent attacks, lingering difficult to heal, the evil stay for a long time, depleting the vital energy, resulting in the function of the internal organs, the vital energy deficiency, as the so-called “long illness more deficiency”. This means that deficiency of vital energy is the main cause of coronary heart disease. The heart resides in the chest, the position of clear Yang, outside the summer gas, its nature is fire, and the sun. The heart resides in the upper jiao, is a yang organ and the main yang qi, the heart is the main blood vessel of the whole body, and it is the main organ of the whole body, and its physiological function is normal or not, and is related to the strength or weakness of yang qi. Where the lungs, liver qi up and down in an orderly manner, the spleen and stomach of the decay and transportation, the kidney yang warm transpiration and gasification, etc., are dependent on the warming effect of the heart yang, so the ancients compared the heart to the “sun”, but also “heart, the ruler of the official” called. Heart Yang is not invigorated, resulting in the upward movement of Yin, water, phlegm, blood stasis, paralysis of the chest Yang, Yang Qi is not passable, not passable is pain. In summary, Yang deficiency and blood stasis is the basic pathogenesis of restenosis after coronary intervention, and the method of warming Yang and invigorating Blood is an important and effective method to treat restenosis after coronary intervention. Therefore, patients should pay attention to keep warm and prevent cold during winter and cold weather changes to prevent the occurrence of restenosis after coronary intervention.
