The concept of coronary heart disease（CHD） is similar to "chest impediment"

"chest pain"in traditional Chinese medicine and its basic pathogenesis is deficiency in origin and excess in superficislity. Clinical epidemiology showed that "yang deficiency and blood stasis" is a common syndrome type in CHD

therefore "strengthening yang and activating blood" becomes one of the main treatment methods of coronary heart disease. Through the study of classical writings and modern literature

the formation and development process of strengthening yang and activating blood therapy was discussed. It is believed that the method of strengthening yang can be divided into warming yang

activating yang and subduing yang. By summarizing the ancient and modern application of strengthening yang and activating blood treatment

and related modern research

this paper provide a support for the clinical application of strengthening yang and activating blood in the treatment of coronary heart disease.
