Professor YUAN Jinqi holds that coronary heart disease（ CHD） is due to phlegm-turbidity obstructing blood circulation at first

and heart vessel is blocked by phlegm and blood stasis gradually. Prof. YUAN looks on coronary atherosclerotic plaque as amassment. Dissipating phlegm

eliminating blood stasis

strengthening vital Qi and removing amassment is used for treatment. Prof. YUAN treats the disease differently according to phlegm or blood stasis pathogen and mild- moderate-severe different syndromes. YUAN puts forward that diagnosing and treating CHD angina pectoris should distinguish cold and heat. It is incorrect to treat all syndromes by warmly dredging method.Heat pain could be divided into Qi depression transforming into heat

flaring up of heart fire

excess of dampnessheat

intermingled Yang deficiency

phlegm-blood stasis blocking and Yangming Fu-viscera excess. YUAN emphasizes that vegetarian diet

reasonable nutrition collocation and maintaining balance of supply and demand of the body is the important diet mode to prevent and treat CHD.
