Chronic heart failure is the terminal stage of cardiovascular disease, characterized by high mortality and high rehospitalization rates, posing a serious threat to human health. Professor Zou Xu leverages the advantages of tradi-tional Chinese medicine in diagnosing and treating heart failure, achieving good results with herbal medicine. This article summarizes Professor Zou Xu's clinical experience and proposes that the key pathogenesis of heart failure lies in the pro-cesses of gradual weakening of heart yang, loss of peace of mind, and mutual entanglement of phlegm and blood stasis. It introduces the experience of using herbal medicine to treat heart failure from three aspects: emphasizing the importance of yang qi, nourishing the heart spirit, and resolving phlegm and promoting blood circulation.
