Abstract

Objective: To determine the efficacy of Shengxian decoction on chronic heart failure CHF and assess its safety.Methods: For efficacy evaluation the rat model of CHF following acute myocardial ischemia was established by ligating the left anterior descending coronary artery. The rats were divided into five groups n=7 per group): sham group model group Shengxian decoction low-dose group 4 g·kg-1), Shengxian decoction high-dose group 16 g·kg-1), and positive drug group. The corresponding medicine or saline were administered via gavage for 35 consecutive days. The rat body weight was recorded and echocardiographic serum biochemical and histopathological assessments were performed at the end of the experiment. For the safety evaluation a one-month repeated-dose study was conducted in rats. The rats were divided into four groups n=30 per group half male and half female): control group Shengxian decoction low-dose group 8 g·kg-1), Shengxian decoction medium-dose group 16 g·kg-1), and Shengxian decoction high-dose group 32 g·kg-1. Medicine or purified water control were administered daily via gavage for 28 days. The general physiological observations were recorded. At the end of the dosing period the indicators such as hematology coagulation serum biochemistry urinalysis and organ coefficients of rats were detected. Histopathological examination was performed on key organs of rats in the high-dose group.Results: The pharmacodynamic study demonstrated that Shengxian decoction significantly ameliorated body weight loss increased left ventricular ejection fraction EF and left ventricular fractional shortening FS), reduced serum levels of creatine kinase CK and lactate dehydrogenase LDH), and reduced pathological lesions in CHF rats. The toxicology study indicated that Shengxian decoction had no toxicologically relevant effects on body weight food consumption hematology coagulation serum biochemistry urinalysis or histopathology up to the highest tested dose. The no-observed-adverse-effect level NOAEL was determined to be >32 g crude drug/kg which is equivalent to 50 times of the clinical human dose.Conclusion: Shengxian decoction exerts a significant protective effect against CHF induced by left anterior descending coronary artery ligation in rats and demonstrates a favorable safety profile.
