Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

Systems Mechanobiology of Cardiac Myocytes [PDF]
Cardiac myocytes are sensitive to specific and distinct mechanical stimuli. We examined the effect of the major axis of biaxial mechanical stretch on cardiac myocyte gene expression and reconstructed a stretch signaling model to identify pathways and transcription factors regulating these responses.

Stochastic resonance with applied and induced fields: the case of voltage-gated ion channels [PDF]
We consider a charged Brownian particle in an asymmetric bistable electrostatic potential biased by an externally applied or induced time periodic electric field. While the amplitude of the applied field is independent of frequency, that of the one induced by a magnetic field is.

Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Abstract Aims Iron deficiency (ID) is prevalent in chronic heart failure (HF) but lacks a consensus definition. This study evaluates the prevalence and the prognostic impact of ID using different criteria on all‐cause and cardiovascular mortality, as well as first hospitalization for HF in patients with new‐onset chronic HF.

A protocol for rapid and parallel isolation of myocytes and non-myocytes from multiple mouse hearts
Summary: This protocol features parallel isolation of myocytes and non-myocytes from murine hearts. It was designed with considerations for (1) time required to extract cardiac cells, (2) cell viability, and (3) protocol scalability.

Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Abstract Background Cardiac remodelling, a crucial aspect of heart failure, is commonly investigated in preclinical models by quantifying cardiomyocyte cross‐sectional area (CSA) and microvascular density (MVD) via histological methods, such as immunohistochemistry.

Abstract Aims Right ventricular (RV) remodelling, a progressive condition characterized by maladaptive cardiac structural and functional changes, primarily results from prolonged pressure overload in patients with pulmonary hypertension (PH). Accurate, universal and easy‐to‐use biomarkers for assessing the severity of RV remodelling are lacking.

Systematic approach to dilated cardiomyopathy diagnosis. Dilated cardiomyopathy is a clinical diagnosis characterized by the presence of left ventricular dilatation and systolic disfunction unexplained by abnormal loading conditions or coronary artery disease.
