Article Abstract
Diabetic cardiomyopathy (DCM) is one of the serious complications of type 2 diabetes mellitus. Vasant Kusumakar Rasa (VKR) is a Herbo-metallic formulation reported in Ayurveda, an Indian system of medicine. The present work was designed to study the effect of VKR in cardiomyopathy in type 2 diabetic rats. Diabetes was induced by feeding a high-fat diet (HFD) for 2 weeks followed by streptozotocin (STZ) administration (35 mg/kg i.p.). VKR was administered orally at dose of 28 and 56 mg/kg once a day for 16 weeks. The results of the study indicated that VKR treatment significantly improved the glycemic and lipid profile, serum insulin, CK-MB, LDH, and cardiac troponin-I when compared to diabetic control animals. VKR treatment in rats significantly improved the hemodynamic parameters and cardiac tissue levels of TNF-α, IL-1β, and IL- 6 were also reduced. Antioxidant enzymes such as GSH, SOD, and catalase were improved in all treatment groups. Heart sections stained with H & E and Masson's trichome showed decreased damage to histoarchitecture of the myocardium. Expression of PI3K, Akt, and GLUT4 in the myocardium was upregulated after 16 weeks of VKR treatment. The study data suggested the cardioprotective capability of VKR in the management of diabetic cardiomyopathy in rats.

Diabetic cardiomyopathy (DCM) is a severe cardiovascular complication of diabetes mellitus, characterized by pathological changes such as cardiomyocyte hypertrophy, necrosis, and myocardial fibrosis, which can ultimately lead to heart failure. However, its underlying mechanisms remain incompletely understood, limiting the development of effective therapeutic approaches. In recent years, the critical roles of oxidative stress and ferroptosis in the pathogenesis of DCM have attracted increasing attention.

Diabetic cardiomyopathy (DCM) is a progressive heart disorder associated with diabetes mellitus, leading to structural and functional cardiac abnormalities. The mechanisms responsible include renin-angiotensin-aldosterone (RAAS) activation, inflammation, apoptosis, and metabolic disturbances. Despite well-established epidemiological links, treatments for DCM are elusive.

One of the most prevalent metabolic diseases in recent years, type 2 diabetes is now one of the top causes of death globally and a significant risk factor for cardiovascular diseases. Therefore, the goal of this study is to investigate the impact of HIIT exercises on the levels of specific proteins associated with mitochondrial biogenesis and apoptosis in the heart tissue of male Wistar rats with type 2 diabetes. Animals in diabetic groups were given a high-fat diet and an intraperitoneal injection of STZ to cause diabetes.

Objective: Beta-hydroxybutyrate (BHB) has been demonstrated to enhance cardiac function in patients with diabetic cardiomyopathy (DCM), the underlying mechanism remains unclear.
Methods: A DCM rat model was established, BHB was administered via intraperitoneal injection. The therapeutic effects of BHB were assessed based on cardiac function, fasting glucose levels, myocardial fibrosis markers and myocardial macrophage polarization.

Diabetes has emerged as a critical global health issue, with its associated complications posing a severe threat to patients' quality of life. Current research demonstrates that imbalance in mitochondrial dynamics and autophagic dysregulation play pivotal roles in the pathogenesis of diabetic complications, particularly in diabetic cardiomyopathy, nephropathy, peripheral neuropathy and retinopathy. Strategic modulation of mitochondrial function and autophagic activity represents a promising therapeutic approach for managing diabetic complications.
