The incidence of myocardial infarction, among the causes of cardiovascular morbidity and mortality, is increasing globally. In this study, left ventricular (LV) dysfunction, including LV systolic and diastolic function, was investigated in a rat myocardial ischemia/reperfusion injury model with echocardiography. The homoisoflavanone sappanone A is known for its anti-inflammatory effects. Using echocardiography, we found that sappanone A administration significantly improved LV systolic and diastolic function in a rat myocardial ischemia/reperfusion injury model, especially in the early phase development of myocardial infarction. Based on myocardial infarct size, serum cardiac marker assay, and histopathological evaluation, sappanone A showed higher efficacy at the doses used in our experiments than curcumin and was evaluated for its potential to improve LV function.

In cardiovascular research, melatonin has shown promise in exhibiting antifibrotic properties and modulating endoplasmic reticulum (ER) stress. However, the exact mechanism by which it influences myocardial fibrosis has not been fully clarified. Therefore, this research aimed to investigate the inhibitory effect of melatonin on the progression of myocardial fibrosis through a mechanism involving the BIP/PERK/CHOP signaling pathway, both in silico and in vivo experimental models.

Myocardial fibrosis, a key pathological feature of hypertensive heart disease (HHD), remains diagnostically challenging due to limited clinical tools. In this study, a FAPI-targeted uptake mechanism previously reported by our group, originally developed for tumor imaging, is extended to the detection of myocardial fibrosis in HHD using [F]F-NOTA-FAPI-MB. The diagnostic performance of this tracer is compared with those of [F]F-FDG, [F]F-FAPI-42, and [F]F-NOTA-FAP2286, and its potential for fluorescence imaging is also evaluated.

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.

Exosomes derived from various cells have been demonstrated to contribute to cardiac repair by regulating macrophage polarization in myocardial infarction. However, how exosomes secreted from cardiomyocytes under hypoxia-ischemia (Hypo-Exo) regulate macrophage polarization in the local tissues is elusive. This study aimed to determine the underlying mechanisms by which Hypo-Exo polarized M2 macrophages.

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.
