Protection of Shengmai Recipe on Improving Cardiac Function and Attenuating Kidney Injury in Pressure Overload Rats / 中草药·英文版

ABSTRACT

Objective: Shengmai Recipe (SMR) is a Chinese patent medicine used for the treatment of chronic heart disease. In order to further assess the renal-protective effect against ischemia lesion of SMR, the cardioprotective effect of SMR on pressure overload-induced left ventricular (LV) systolic dysfunction and the potential mechanism on alleviating myocardial damage, myocardial fibrosis, and renal ischemia lesion in chronic heart failure (CHF) rats were investigated. Methods: Rats with partially ligated abdominal aorta were randomly divided into model, Sham, and SMR groups. One week after recovery from surgery, animals were preventively ig administered with SMR at the dose of 810 mg/kg once daily for 8 weeks. Cardiac function and structure, endogenous biomarkers (CK-MB and LDH), myocardial fibrosis, and organ pathological change were estimated by echocardiography, immunodepression and velocity method, hematoxylineosin staining, and masson's trichrome staining, respectively. Results: The administration of SMR significantly decreased serum CK-MB and LDH levels and reduced myocardial fibrosis. Interestingly, SMR not only improved cardiac function but also ameliorated kidney injury induced by ischemia in CHF rats. Conclusion: SMR could enhance the LV contractile function, reduce myocardial necrosis, and reverse LV remodeling in CHF rats, and most importantly, SMR could be used to treat the renal ischemia injury in pressure overload rats.
