Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

ESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
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 ...

Is mavacamten superior to aficamten for hypertrophic cardiomyopathy? A frequentist network meta-analysis [PDF]

Exploration of Cardiology
Background: Myosin inhibitors have been shown to improve exercise capacity and symptoms, as well as reduce the left ventricular outflow tract (LVOT) gradient. This study explores the efficacy of mavacamten versus aficamten in hypertrophic cardiomyopathy (

SETD3 is an actin histidine methyltransferase that prevents primary dystocia. [PDF]

, 2019
For more than 50 years, the methylation of mammalian actin at histidine 73 has been known to occur1. Despite the pervasiveness of His73 methylation, which we find is conserved in several model animals and plants, its function remains unclear and the ...

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

Journal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

Examining the role of insulin in the regulation of cardiovascular health [PDF]

, 2013
A substantial body of evidence has reported that insulin has direct actions on the cardiovascular system independent of its systemic effects on plasma glucose or lipids.

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

Interdisciplinary Medicine, EarlyView.
This study reveals that small extracellular vesicles (sEVs) from visceral fat compromise coronary microcirculation in a mouse model of heart failure with preserved ejection fraction (HFpEF). The SGLT2 inhibitor canagliflozin emerges as a therapeutic strategy, improving cardiac function and endothelial health.

Why has positive inotropy failed in chronic heart failure? Lessons from prior inotrope trials. [PDF]

, 2019
Current pharmacological therapies for heart failure with reduced ejection fraction are largely either repurposed anti-hypertensives that blunt overactivation of the neurohormonal system or diuretics that decrease congestion.

Pharmacokinetics, disposition, and biotransformation of the cardiac myosin inhibitor aficamten in humans

Pharmacology Research & Perspectives
AbstractAficamten, a cardiac myosin inhibitor, is being developed for the treatment of patients with symptomatic hypertrophic cardiomyopathy (HCM). The purpose of this study was to determine the absorption, metabolism, and excretion of aficamten. Eight healthy male participants received a single oral dose of 20 mg aficamten (containing approximately ...

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

Journal of Intelligent Medicine, EarlyView.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Magnetic resonance imaging evaluation of the effects of myosin inhibitors (mavacamten and aficamten) in hypertrophic cardiomyopathy: a systematic review and case report

Monaldi Archives for Chest Disease
Hypertrophic cardiomyopathy (HCM) is a common inherited cardiac disorder, affecting approximately 1 in 250 individuals. It is defined by unexplained left ventricular (LV) hypertrophy in the absence of other identifiable cardiac or systemic causes.
