Objective To investigate the relationship between left ventricular remodeling and syndrome elements and risk factors. Methods Using clinical epidemiological investigation methods

261 patients with suspected coronary heart disease underwent coronary angiography and echocardiography

and cross-sectional survey was conducted for traditional Chinese medicine（ TCM） syndromes and risk factors in patients with left ventricular remodeling diagnosed as coronary heart disease. The frequency analysis and the association rule method were used for data statistics.Results Totally 231 cases were final diagnosed of left ventricular remodeling in 261 suspected patients. Among the231 patients

the main pathogenic factors were heart（ 226 cases）

lung（ 116 cases）

and kidney（ 69 cases）; the main pathogenic factors were blood stasis（ 221 cases）

qi deficiency（ 77 cases）

yin deficiency（ 72 cases）

and yang deficiency（ 58 cases）. The association rule suggested that left ventricular remodeling was related to heart

lung

kidney

blood stasis

qi deficiency

yang deficiency

yin deficiency. The probability of left ventricular remodeling was 98. 49% under smoking

age

male

heart

and blood stasis conditions. For two syndrome elements

the combination of heart and yang deficiency

heart and qi deficiency were more common in patients with left ventricular remodeling of coronary heart disease. For three syndrome elements

the combination of heart

yang deficiency and kidney

heart

yang deficiency and lung were more common. For four syndromes

the combination of the heart

yang deficiency

kidney and blood stasis

heart

yang deficiency

lung and blood stasis were more common. Conclusion Patients with left ventricular remodeling in coronary heart disease are more likely to have root deficiency and manifestation excess

and the disease location is mostly related to heart

lung and kidney. Deficiency of qi

yin deficiency and yang deficiency were the causes of the disease. Blood stasis and phlegm are the targets of the disease

and risk factors are important factors for the onset of the disease.
