Hyperlipidemia represents a major risk factor for cardiovascular diseases leading to myocardial injury (MI). The present study aimed to illustrate the pattern of myocardial injury induced in diabetic hyperlipidemic rat model and the effect of vitamin D3, 10-dehydrogingerdione (10-DHGD) intake either individually or in combination form.

Despite improvements in interventional techniques leading to faster myocardial reperfusion postmyocardial infarction, there has been a significant rise in the occurrence of myocardial ischaemia/reperfusion injury (MI/RI). A deeper understanding of the underlying mechanisms of MI/RI could offer a crucial approach to reducing myocardial damage and enhancing patient outcomes. This study examined the myocardial protective properties of puerarin (PUE) in the context of MI/RI using hypoxia/reoxygenation (H/R) or ischaemia/reperfusion (I/R) injury models were employed in H9c2 cells and C57BL/6 mice.

In one of the earliest reports from China during COVID-19, it was noted that over 20% of patients hospitalized with the disease had significant elevations of troponin, a marker of myocardial tissue damage, that put them at a higher risk. In a hypothesis-independent whole exome sequencing (WES) study in hospitalized COVID-19 patients of diverse ancestry, we observed putative enrichment in pathogenic variants in genes known to be involved in the pathogenesis of cardiomyopathy. This observation led us to hypothesize that the observed high morbidity and mortality in these patients might be due to the presence of rare genetic factors that had previously been silent but became relevant as a consequence of the severe stress inflicted by an infection with SARS-CoV-2.

Sodium-glucose co-transport protein 2 (SGLT2) inhibitors, a novel category of oral hypoglycemic agents, offer a promising outlook for individuals experiencing heart failure with reduced ejection fraction. Evidence is emerging that highlights their potential in alleviating myocardial fibrosis and oxidative stress. However, the precise mechanisms through which SGLT2 inhibitors influence myocardial fibrosis induced by angiotensin II (Ang II) or transforming growth factor-β1 (TGF-β1) are not fully understood.

Nuclear factor erythroid 2-related factor 2 (NRF2) is a redox-sensitive transcriptional factor that enables cells to resist oxidant responses, ferroptosis and inflammation. Here, we set out to probe the effects of NRF2 on cardiomyocyte injury under acute myocardial infarction (AMI) condition and its potential mechanism. Human cardiomyocytes were exposed to hypoxia/reoxygenation (H/R) to induce cell injury.

Hypoxia-mediated cardiac tissue injury and its repair or regeneration are one of the major health management challenges globally. Unlike mammals, lower vertebrate species such as zebrafish (Danio rerio) represent a natural model to study cardiac injury, repair and regeneration. Thyroxine (T3) has been hypothesised to be one of the endocrine factors responsible for the evolutionary trade-off for acquiring endothermy and regenerative capability in higher vertebrates.
