The intelligent diagnosis and treatment system for coronary heart disease（CHD） has been greatly developed along with the advancement of global artificial intelligence technology. However

due to the complexity

dynamics and developmental characteristics of traditional Chinese medicine（TCM） for human diseases

the current diagnosis and treatment of CHD with integrated Chinese and Western medicine still fail to reflect the characteristics of TCM thinking. The holistic view and syndrome differentiation are the basic elements of TCM thinking. The coordination of commonality and individuality is a major feature of TCM clinical thinking. The TCM diagnosis and treatment knowledge model based solely on epidemiological research results is contrary to the requirements of TCM thinking.This paper analyzed the characteristics and problems of existing TCM diagnosis and treatment knowledge model

combined with the application of the commonly used algorithms in the TCM diagnosis and treatment model

and put forward the idea of constructing a syndrome-based diagnosis and treatment knowledge model based on TCM thinking for CHD with angina pectoris. That is to introduce the concept of syndrome elements in the combination of disease and syndrome

with the guidance of TCM thinking

standardization as the basis of the previous stage

the combination of disease and syndrome as the realization method

the "disease-syndromes-syndrome elements-symptoms"as the diagnosis order

and the "treatment principles

methods

prescriptions and herbs"as diagnosis and treatment route

in order to achieve the purpose of intelligent prescription

to promote the development of intelligent diagnosis and treatment technology for CHD syndrome with integrated Chinese and western medicine.
