Diabetic cardiomyopathy (DCM) is an age-related disease, and its progression is accompanied by hyperglycaemia, cardiac dysfunction, and myocardial structural and functional abnormalities. Cissus quadrangularis, a traditional medicinal plant, contains polyphenols, flavonoids, phytosterols, carbohydrates and ascorbic acid. It is used to treat osteoporosis, asthma, haemorrhoids and menstrual disorders. Objective: In the current research, we have investigated the effect of ethanolic extract of C. quadrangularis (EECQ) against a high-fat diet (HFD)/streptozotocin-induced DCM by estimating cardiac biomarkers, inflammatory markers and Reactive oxygen species (ROS) production. Rats were fed with an HFD for 12 weeks, followed by single-shot low-dose streptozotocin (35 mg/kg; i.p.). The treatment was performed by EECQ (200 mg/kg/day, orally) for six weeks. The extract EECQ improves glucose, insulin tolerance tests and hypercholesteremia. DCM is characterized by cardiac dysfunction, cardiac biomarkers CKMB and LDH, which were attenuated by the EECQ treatment. The hypertrophic biomarker ANP, BNP expression and cardiomyocyte surface area were decreased by EECQ. Moreover, EECQ also alleviated the biomarkers Angiotensin II and renin level. EECQ also reduced oxidative stress, ROS production and cardiac inflammation. Thus, these findings suggested that EECQ could be used as a possible therapeutic regiment to treat DCM. Cissus quadrangularis ameliorates hyperglycaemia, hyperinsulinemia and hyperlipidaemia. Cissus quadrangularis mitigates cardiac dysfunction. Cissus quadrangularis decreases RAAS activation, thereby down-regulates ANP, BNP expression. Cissus quadrangularis alleviates ROS propagated oxidative stress and apoptosis. [ABSTRACT FROM AUTHOR]
