Analysis of animal models of heart failure based on characteristics of clinical symptoms of traditional Chinese and Western medicine / 中国中药杂志

ABSTRACT

The incidence of heart failure has increased year by year, with a negative impact on quality of life and life expectancy of patients. Reproduction of animal models that meet the characteristics of clinical symptoms is a prerequisite for conducting experimental studies relating to heart failure. Based on the characteristics of clinical symptoms of heart failure in traditional Chinese medicine(TCM) and Western medicine, the existing common animal models of heart failure were explored, and the clinical anastomosis of the existing animal models was analyzed based on the clinical diagnostic criteria of heart failure in TCM and Western medicine. After analysis and comparison, it can be seen that the existing modeling methods are mostly single-factor animal models, with certain gaps between the characteristics of clinical multi-factors and interactions that jointly lead to heart failure, and the modeling methods were mostly guided by Western medicine, with a lack of TCM pathogenic factors in the model process, which is different from the clinical diagnostic criteria of Chinese and Western medicine for heart failure. In terms of syndrome differentiation, heart failure is classified into heart and lung Qi deficiency syndrome, Qi and Yin deficiency syndrome, heart and kidney Yang deficiency syndrome, Qi deficiency and blood stasis syndrome, Yang deficiency and water flooding syndrome, phlegm-drinking obstructive lung syndrome, Yin and yang exhausted syndrome. The existing animal models mostly confused them, with no effective and recognized method for modeling at present. There are major limitations in studies of Chinese medicine. Therefore, based on clinical characteristics of heart failure in Chinese and Western medicine, this article analyzed the existing animal models, defined their advantages and disadvantages and application prospects, and then suggested further improving the corresponding animal models of heart failure and standardizing the model evaluation, so as to improve the clinical coincidence between animal models and Chinese and Western medicine, make heart failure animal models better serve scientific studies, and promote relevant mechanism studies, pathological change studies and drug screening.
