ABSTRACT
Objective To analyze the mechanism of interaction between cardiac and renal failure and observe the protective effects of Zhenwu decoction on cardio-renal syndrome rats. Methods The rats were divided into five groups: Sham group, MI (myocardial infarction) group, MI merger STNx group, MI intervention group, MI merger STNx intervention group. The first three groups were fed with saline (NS) for two weeks after surgery. The latter two groups of rats were fed with an equal volume of Zhenwu decoction. The cardiac function of rats in each group were evaluated , including the mass of heart , left ventricle and left kidney weights as a ratio of body weight, fractional shortening and left ventricular ejection fraction. And serum levels of indoxyl sulfate and serum creatinine were also achieved. Results MI merger STNx could further aggravate the heart function, kidney function and left ventricular remodeling in rats. Zhenwu decoction could obviously improve the heart function, kidney function and left ventricular remodeling in rats. Conclusions Based on the MI models, STNx can worsen heart function and kidney function. Zhenwu decoction can significantly improve heart function and kidney function.
