Reactivation of the mitosis-promoting factor in postmitotic cardiomyocytes [PDF]

open access: yes, 2003
Cardiomyocytes cease to divide shortly after birth and an irreversible cell cycle arrest is evident accompanied by the downregulation of cyclin-dependent kinase activities.

The in‐hospital administration of sacubitril/valsartan in acute myocardial infarction: A meta‐analysis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 998-1012, April 2025.
In patients with Acute Myocardial Infarction related heart failure, the in‐hospital administration of ARNIs was associated with a reduced risk of MACEs and re‐hospitalizations for heart failure, as well as cardiac remodeling, compared to standard therapy.

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
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).

Functional role of t-tubules on calcium transients in canine cardiac myocytes

open access: yesHeart and Mind, 2019
Background: A loss of t-tubules and alterations in ultrastructure occur in cultured ventricular myocytes. A similar alteration in t-tubules and ultrastructure is well documented under certain pathological conditions such as heart failure. We examined the

PI3Ks maintain the structural integrity of T-tubules in cardiac myocytes. [PDF]

open access: yesPLoS ONE, 2011
Phosphoinositide 3-kinases (PI3Ks) regulate numerous physiological processes including some aspects of cardiac function. Although regulation of cardiac contraction by individual PI3K isoforms has been studied, little is known about the cardiac ...

Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]

open access: yes, 2009
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Increased sarcolemmal Na+/H+ exchange activity in hypertrophied myocytes from dogs with chronic atrioventricular block

open access: yesFrontiers in Physiology, 2013
Dogs with compensated biventricular hypertrophy due to chronic atrioventricular block (cAVB), are more susceptible to develop drug-induced Torsade-de-Pointes arrhythmias and sudden cardiac death.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
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.

The effect of exercise training on transverse tubules in normal, remodeled, and reverse remodeled hearts [PDF]

open access: yes, 2011
The response of transverse (T)-tubules to exercise training in health and disease remains unclear. Therefore, we studied the effect of exercise training on the density and spacing of left ventricle cardiomyocyte T-tubules in normal and remodeled hearts ...

Prognostic impact of iron deficiency in new‐onset chronic heart failure: Danish Heart Failure Registry insights

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1346-1357, April 2025.
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.
