Chinese medicine believes that the lung is the master of qi, the spleen is the master of transportation, the kidney is the root of qi, and the liver is the master of drainage. If the liver is depressed and qi stagnant or the spleen loses transportation and transformation, the fluid cannot be distributed and becomes phlegm, and the phlegm congests the lung, the lung qi is unfavorable, which can lead to phlegm stasis and paralysis of the heart and heart failure. Thus, although the location of heart failure is in the heart, the onset of the disease is closely related to the internal obstruction of phlegm due to dysfunction of the lung, spleen, kidney and liver. In congestive heart failure, acute left heart failure can be characterized by palpitations at night, seated breathing, roaring in the throat and other pulmonary edema symptoms; in right heart failure or total heart failure, shortness of breath, inability to lie down, abdominal edema and chest tightness, chest closure, heart pain in the back and other symptoms, all of which are closely related to phlegm in Chinese medicine. Treatment with phlegm-opening drugs can strengthen the efficacy of blood-activating and blood-stasis-removing drugs. The phlegm-liberating drugs can significantly increase the mobility of blood and reduce its viscosity, thus improving the flow state of blood and improving cardiac insufficiency. However, when heart failure patients have phlegm and heat, they should follow the principle of heat and cold, and be treated with drugs to clear heat and resolve phlegm. The treatment with anti-heart failure western medicine can rapidly relieve the clinical symptoms of various heart failure patients, such as Gua Ao Ren, Bian Nan Xing, Chuan Bei Mu, etc.
