The present study aims to evaluate the antihyperlipidaemic, antihypertrophic, and reducing effects of zingerone on isoproterenol-induced hyperlipidaemia and hypertrophy in rats. Rats were pretreated with zingerone (6 mg/kg body weight) daily for a period of 14 days and then induced myocardial infarction with isoproterenol (100 mg/kg body weight) on days 15 and 16. Isoproterenol increased serum creatine kinase and lactate dehydrogenase activities in the rats. Increased levels/concentrations of serum and heart cholesterol and triglycerides were observed in isoproterenol-induced myocardial infarcted rats. Isoproterenol also altered serum lipoproteins and the activity of liver 3-hydroxy-3-methyl glutaryl-coenzyme-A-reductase in the rats. The in vitro study revealed a very convincing reducing power of zingerone. Pretreatment with zingerone prevented hyperlipidaemia and cardiac hypertrophy, by virtue of its antihyperlipidaemic, antihypertrophic, and reducing properties in isoproterenol-induced myocardial infarcted rats.
