Abstract:
Objective To observe the protective effect of Qiangxin oral liquid on experimental left ventricular hypertrophy induced by isoproterenol and ultrastructure in rats.MethodsMyocardial hypertrophy model of rats were established by injection of isoproterenol (5 mg/kg/d) for 7 days. Thirty rats were divided into the control group, model group and treatment group (treated with Qiangxin oral liquid from second day after myocardial hypertrophy model made and continued for 12 weeks). Cardiac structure and function were detected in all groups by ultrasonography on 2nd, 6th and 12th week after model made respectively. After 12 weeks, the left ventricular weight/body weight index (LVW/BW) of all animals was tested and myocardial ultrastructure was examined.ResultsCompared with the model group, the interventricular septal end systolic thickness, left ventricular posterior wall thickness, left ventricular diameter, and left ventricular mass index of the treatment group decreased significantly ( P<0.05～0.01), while the damage of myocardial ultrastructrue lightened.ConclusionQiangxin oral liquid can improve the experimental myocardial hypertrophy of rats induced by isoproterenol.
