Characteristics of traditional chinese medicine syndrome in patients with coronary heart disease at different disease stages

Coronary atherosclerotic heart disease (CHD) has a high incidence, disability rate, and mortality rate, which severely affect people's health, work, and life. Based on its clinical manifestations, traditional Chinese medicine (TCM) has classified CHD as “chest impediment” and “heart pain” for the treatment. The course of CHD is protracted, and the pathogenesis is complex and changeable. Moreover, different disease stages have different syndrome characteristics. Thus, this article aimed to summarize the classification and distribution characteristics of the TCM syndrome in various stages of CHD, such as before and after percutaneous coronary intervention therapy, disease progression, age, and complications, to provide references for the TCM clinical diagnosis and treatment of CHD.
