Background: The role of a prothrombotic state in atrial fibrillation (AF) progression to permanent arrythmia (PerAF) is unclear. Formation of denser and poorly lysable fibrin clots has been observed in AF patients also with sinus rhythm in association with higher stroke risk. We investigated whether altered fibrin clot properties and other prothrombotic state markers may contribute to AF transition to PerAF.

Monitoring cardiac rhythm is crucial for diagnosis of heart failure. However, the deficient sensitivity of polyvinylidene fluoride (PVDF) sensors impede their application in monitoring of cardiac rhythm due to the limited piezoelectricity. Here, doping of CoFeO and aligning fibers were jointly adopted to enhance the piezoelectricity of PVDF, attributed to the transformation of α-PVDF to β-PVDF from 51.

The importance of ferroptosis in the occurrence and progression of atherosclerosis is gradually being recognized. The stimulatory G protein α subunit (Gsα) plays a crucial role in the physiology of endothelial cells (ECs). Our previous study showed that endothelial Gsα could regulate angiogenesis and preserve endothelial permeability.

A diabetic heart is characterized by fibrosis, autophagy, oxidative stress, and altered mitochondrial functions. For this review, three databases (PubMed, EMBASE, and Web of Science) were searched for articles written in English from September 2023 to April 2024. Studies that used exercise training for at least 3 weeks and which reported positive, negative, or no effects were included.

Diabetic microvascular dysfunction is evidenced by disrupted endothelial cell junctions and increased microvascular permeability. However, effective strategies against these injuries remain scarce. In this study, the type 2 diabetes mouse model was established by high-fat diet combined with streptozotocin injection in Rnd3 endothelial- specific transgenic and knockout mice.
