One of the major complications of diabetes mellitus (DM) is diabetic cardiomyopathy (DCM) due to the multifaceted therapy involved. Here, we evaluated the combinatorial effect of Moringa leaf (ML) and seed (MS) supplemented diets plus acarbose (ACA) on cardiac acetylcholinesterase (AChE), adenosine triphosphatase (ATPase), adenosine deaminase (ADA), monoamine oxidase (MAO), arginase, angiotensin-I converting enzyme (ACE), and lactate dehydrogenase (LDH) activities, thiobarbituric acid reactive species (TBARS), and thiols levels. The diets and ACA (25 mg/kg) were administered for 14 days. The fasting blood glucose level (FBGL), cardiac AChE, ATPase, ADA, MAO, arginase, ACE, LDH activities, and TBARS and thiol levels were determined. Relative to the normal rats, the biomarkers were significantly increased in DM rats but were suppressed significantly in the diets plus ACA-treated rats while improving antioxidant status, with the 4% Moringa plus ACA proving outstanding compared to individual ML/MS and ACA. In addition, ML-supplemented diets with/without ACA had better effects compared to MS with/without ACA, respectively. In conclusion, the combination of ML/MS supplemented diets and ACA synergistically modulates the tested biochemicals. However, the effect on blood vessels and the nerves that control the heart, stiffness of left ventricular (LV) hypertrophy, fibrosis, cell signaling abnormalities, related gene expression, clinical trials, and echocardiology studies should be further investigated to affirm this claim. PRACTICAL APPLICATIONS: Moringa oleifera has been a vocal appetite in mitigating cardiovascular disease induced by diabetes, but the formulation of a medicinal diet as an ameliorative route of attention to the pathology is fairly addressed, not talking of its combination with the synthetic antidiabetic drug, such as ACA. Based on this experiment, it is imperative to explore such an idea. This research shows that co-administration of moringa leaf/seed formulated diets plus ACA exhibits a synergistic effect in DCM management. However, further research is needed in this field of experiment.
