To investigate the correlation between TCM syndrome element, syndrome distribution and cardiac color ultrasound, 90 patients are divided into five groups according to the syndrome type: syndrome of qi deficiency of heart and lung, deficiency of both qi and yin, syndrome of qi deficiency and blood stagnation, syndrome of water overflowing due to yang deficiency, and syndrome of yang deficiency of heart and kidney, to extract and analyze the distribution of CHF syndrome element. 18 healthy volunteers are enrolled as the normal control group to study the correlation between NYHA cardiac function grading and cardiac color ultrasound. The results show that the distribution of CHF syndrome element is as follows: root deficiency syndrome element in which disease location is dominated by heart (94.4%) and disease natures is dominated by qi deficiency (82.2%), and the superficial sthenia syndrome element dominated by the blood stagnation (70.0%). Conclusion: The CHF pathogenesis is characterized by deficient root and excessive superficiality, disease location is dominated by heart, and the symptom element of disease nature is rooted by qi deficiency and is marked by blood stagnation. Cardiac color ultrasound is an important examination method for CHF, its parameters have significant differences among the syndrome type groups, and it can be used as an important auxiliary means for CHF TCM syndrome differentiation. Different CHF syndrome types are significantly different in the levels, which can be used as important reference index for CHF TCM syndrome differentiation. (C) 2018 Elsevier B.V.
