Type 2 diabetes mellitus (DM) is a common metabolic disorder predisposing to diabetic cardiomyopathy and atherosclerotic cardiovascular disease (CVD), which could lead to heart failure through a variety of mechanisms, including myocardial infarction and chronic pressure overload. Pathogenetic mechanisms, mainly linked to hyperglycemia and chronic sustained hyperinsulinemia, include changes in metabolic profiles, intracellular signaling pathways, energy production, redox status, increased susceptibility to ischemia, and extracellular matrix remodeling...

BACKGROUND: Increased reactive oxygen species (ROS) generation in diabetes mellitus (DM) is an important mechanism leading to diabetic cardiomyopathy. Apocynin, a drug isolated from the herb Picrorhiza kurroa, is considered an antioxidant agent by inhibiting NADPH oxidase activity and improving ROS scavenging. This study analyzed the influence of apocynin on cardiac remodeling in diabetic rats. METHODS: Six-month-old male Wistar rats were assigned into 4 groups: control (CTL, n = 15), control + apocynin (CTL + APO, n = 20), diabetes (DM, n = 20), and diabetes + apocynin (DM + APO, n = 20)...

Diabetic cardiomyopathy (DCM) is one of the chief diabetes mellitus complications. Inflammation factors may be one reason for the damage from DM. The purpose of this research is to study the potential protective effects of puerarin on DM and the possible mechanisms of action related to NF-κB signal pathway. Following administration of puerarin to the disease model rat, several changes were observed including the changes of serum biochemical index, improved diastolic dysfunction, and enhanced endogenous antioxidant enzymes activities, further NF-κB signaling activation...

Noncardiac comorbidities such as diabetes mellitus (DM) have different outcomes in heart failure with preserved ejection fraction (HFpEF) compared with heart failure with reduced ejection fraction (HFrEF). These different outcomes are the result of distinct myocardial effects of DM on HFpEF and HFrEF, which relate to different mechanisms driving myocardial remodeling in each heart failure phenotype. Myocardial remodeling is driven by microvascular endothelial inflammation in HFpEF and by cardiomyocyte cell death in HFrEF...

Cardiovascular disease, predominantly ischemic heart disease (IHD), is the leading cause of death in diabetes mellitus (DM). In addition to eliciting cardiomyopathy, DM induces a 'wicked triumvirate': (i) increasing the risk and incidence of IHD and myocardial ischemia; (ii) decreasing myocardial tolerance to ischemia-reperfusion (I-R) injury; and (iii) inhibiting or eliminating responses to cardioprotective stimuli. Changes in ischemic tolerance and cardioprotective signaling may contribute to substantially higher mortality and morbidity following ischemic insult in DM patients...

Changes in sensory and sympathetic innervation during diabetes mellitus (DM) can be a predictor of arrhythmias, silent myocardial ischemia, and chronic heart failure, but knowledge about these changes is still unsatisfactory. We analyzed whether prolonged DM induces changes in density of sensory and sympathetic nerve terminals of rat's heart and whether it contributes to cardiomyopathy during aging. DM was induced by i/p injecting 55 mg/kg streptozotocin to male Sprague-Dawley rats, while a control group received a citrate buffer...

Autophagy serves a role in preserving cellular homeostasis. Diabetes mellitus (DM) impairs cardiac autophagy and is associated with an accumulation of cytotoxic proteins that may provoke apoptosis and damage cardiomyocytes. Histone deacetylase (HDAC) inhibitors attenuate cardiac fibrosis and inflammation, and improve cardiomyopathy resulting from DM. However, the effect of HDAC inhibition on autophagy in DM cardiomyopathy has not been investigated. The purpose of the present study was to evaluate whether HDAC inhibition modulates cardiac autophagy and to investigate the potential mechanisms in type 2 DM (T2DM) hearts...

The effects of melatonin (MLT), which exerts cardioprotective effects against myocardial apoptosis, in long‑term diabetic cardiomyopathy are not currently well defined. The present study aimed to investigate how MLT protects the heart through modulating myocardial apoptosis in rats with type 2 diabetes mellitus (DM). In total, 36 rats were randomly divided into three groups, including control (n=12), DM (n=12) and DM + MLT (n=12) groups. The results demonstrated that, in DM rats, a significant increase was observed in the serum fasting blood glucose and lipid levels, in addition to insulin resistance and cardiac dysfunction, which were attenuated in DM rats treated with MLT...

BACKGROUND/AIMS: Apoptosis, fibrosis and NLRP3 inflammasome activation are involved in the development of diabetic cardiomyopathy (DCM). Human recombinant relaxin-3 (H3 relaxin) is a novel bioactive peptide that inhibits cardiac injury; however, whether H3 relaxin prevents cardiac injury in rats with DCM and the underlying mechanisms are unknown. METHODS: To investigate the effect of H3 relaxin on DCM, we performed a study using H3 relaxin treatment in male Sprague-Dawley (SD) rats with streptozotocin (STZ)-induced diabetes (DM)...

Patients with type 1 and type 2 diabetes mellitus (T1D and T2D) show an increased incidence of heart failure (HF) even after adjustment for well established risk factors for HF such as hypertension and ischaemic heart disease. The resulting specific form of cardiomyopathy is known as diabetic cardiomyopathy" (DCM). Pathogenetic mechanisms underlying DCM are likely to be multifactorial, from altered myocardial metabolism (hyperglycaemia, hyperinsulinaemia, increased circulating fatty acids and trglycerides) to microvascular disease, autonomic neuropathy, and altered myocardial structure with fibrosis...

BACKGROUND: Diabetic cardiomyopathy is identified as cardiac ventricular dysfunction induced by an insulin shortage in diabetic patients. Our previous studies have shown that Polydatin (PD) alleviates cardiac dysfunction after myocardial infarction (MI) injury. Nevertheless, the mechanism by which PD regulates diabetic cardiomyopathy has not been reported. METHODS: In this study, we demonstrated the effects and described the mechanisms of PD in diabetic cardiomyopathy in both adult mouse hearts and neonatal mouse cardiomyocytes...
