According to the theory of traditional Chinese medicine, the center of the five elements is “fire”, which is the “Yang organ”. Heart Yang has the function of warming and promoting, and the function of the heart as the master of blood vessels depends on the warming of Heart Yang. Heart energy is dependent on the vitality of heart yang, which in turn helps to stimulate heart yang. Heart qi over time, tired of yang, heart qi deficiency, heart yang weak in different stages of pathology, reflecting the different degrees of heart failure, that is, qi is the gradual yang, yang for qi more. The various changes produced by the movement of qi are called qi-chemistry. The production, distribution and excretion of waste materials in the body are dependent on the function of qi-chemistry. Disorders of qi causing qi-transformation can reduce the production of yin fluids; or yin in the body, or excessive use of diuretics can lead to yin evidence. Some studies have shown that the initiating factor of heart failure is qi; in early heart failure, qi and yin are predominant; in middle heart failure, qi and yin are transformed to heart yang; in late severe heart failure, yang is predominant. Therefore, imbalance of yin and yang is the basis of the pathological evolution of heart failure, and the treatment of heart failure should pay attention to the balance of yin and yang, and adjusting the imbalance of yin and yang is a treatment method that cannot be ignored in the treatment of heart failure.
