The abundance of epicardial adipose tissue (EAT) is associated with atrial fibrillation (AF), the most frequent cardiac arrhythmia. However, both the origin and the factors involved in EAT expansion are unknown. Here, we found that adult human atrial epicardial cells were highly adipogenic through an epithelial-mesenchymal transition both in vitro and in vivo. In a genetic lineage tracing the WT1(CreERT2+/-)Rosa(tdT+/-) mouse model subjected to a high-fat diet, adipocytes of atrial EAT derived from a subset of epicardial progenitors...

AIMS: Cardiac resynchronization therapy (CRT) induces reverse cardiac remodelling in heart failure (HF), but many patients receiving CRT remain non-responders. This study assessed the role of amino-terminal-pro-B-type natriuretic peptide (NT-proBNP), mid-regional-pro-atrial natriuretic peptide (MR-proANP), and mid-regional-pro-adrenomedullin (MR-proADM) at the time of device implantation to predict favourable clinical course (CRT response and/or risk of MACE) in HF patients receiving CRT...

BACKGROUND AND PURPOSE: Risk assessment of chronic cardiac safety liabilities within the pharmaceutical industry is mostly performed during late stages of pre-clinical drug development using in vivo animal models. Here, we explored the potential of human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs) to detect chronic cardiac risks such as drug-induced cardiomyocyte toxicity. EXPERIMENTAL APPROACH: Video microscopy-based motion field imaging was applied to evaluate chronic effect (over 72 h) of cardiotoxic drugs on the contractile motion of hiPS-CMs...

A continuous flow extracorporeal ventricular assist device (VAD) was modified to support functionally univentricular infants and children awaiting heart transplantation. A centrifugal VAD, designed to flow from 1.5 to 8 L/min, was used as a bridge-to-transplant in four patients with functionally univentricular circulation. A variable restrictive recirculation shunt permitted lower flow ranges in small patients. In hypoxic patients, an oxygenator was incorporated into the circuit. From 2012 to 2015, the modified VAD was placed in four patients with Glenn physiology...

: The aim of this study was to determine if atrial natriuretic peptide can be used as an early screening tool for hypertrophic cardiomyopathy in Maine coon cats. ANIMALS: The study was performed in 43 Maine coon cats of both sexes, aged 11 to 92 months. Clinical and echocardiographic examinations were done and proANP serum concentrations were measured every three months over a period of one year (each cat had a total of five examinations). Cats were divided into 3 groups based on echocardiographic results: group 1 - healthy cats, group 2 - cats with unequivocal hypertrophic cardiomyopathy results, group 3 - cats with HCM...

Activation of resident and infiltrating immune cells is a central event in training adaptation and other contexts of skeletal muscle repair and regeneration. A precise orchestration of inflammatory events in muscle fibers and immune cells is required after recurrent contraction-relaxation cycles. However, the mechanistic aspects of this important regulation remain largely unknown. We now demonstrate that besides a dominant role in controlling cellular metabolism, the peroxisome proliferator-activated receptor γ co-activator 1α (PGC-1α) also has a profound effect on cytokine expression in muscle tissue...

BACKGROUND: Higher N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels have been linked to a more favorable glucometabolic profile. Little is known about the interaction of NT-proBNP and fasting glucose in non-ST-segment elevation acute coronary syndrome (NSTE ACS). METHODS: Fasting glucose and NT-proBNP were measured in 2240 patients enrolled in the EARLY ACS trial. Multivariable Cox models were used to assess associations between fasting glucose and NT-proBNP and a 96-hour composite of death, myocardial infarction (MI), recurrent ischemia, or thrombotic bailout; 30-day death or MI; and 1-year mortality...

BACKGROUND: Left ventricular (LV) remodeling is closely linked to the progression of heart failure. There are limited data on the epidemiology of new onset LV remodeling among elderly women, which requires further investigation. METHOD: We examined data from a community-based cohort of women aged > 65 years, who had received > 2 echocardiography scans from 2009 to 2014. Exclusion criteria for patients included prior echocardiographic evidence of left ventricular enlargement (LVE) or hypertrophy (LVH)...

BACKGROUND: The relationship between N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac structural or functional anomalies in pre-clinical, asymptomatic Asian populations has not been well identified. METHODS: From October 2005 to March 2008, we enrolled consecutive asymptomatic adults with preserved global left ventricular (LV) function (ejection fraction>50%) who underwent annual cardiovascular health survey. Circulating NT-proBNP was used to identify echo-defined cardiac structural/functional anomalies and compared to current recommended cut-off from the European Society of Heart Failure...

OBJECTIVE: Vasoactive cardiovascular hormones such as the N-terminal prohormone of brain natriuretic peptide (NT-proBNP) are produced upon ventricular stretch and play a central role in neurohumoral pathways of the heart regulating cardiovascular remodeling and volume homeostasis. The impact of HIV infection on these neurohumoral pathways of the heart and its potential reversibility by combinations of antiretroviral therapies remain unclear. METHODS: We assessed serum levels of NT-proBNP in 219 antiretroviral therapy-naïve HIV-infected patients with a normal cardiac and renal status at treatment initiation and after attainment of viremic control...

BACKGROUND: Olmesartan and azilsartan, angiotensin II receptor blockers (ARBs), are expected to decrease blood pressure more than the other ARBs. We conducted randomized-controlled trials to compare the practical efficacy of olmesartan with azilsartan. METHODS: Eighty-four patients treated with the conventional ARBs for more than 3 months were assigned randomly to receive either 20 mg of olmesartan (olmesartan medoxomil, OL group) or 20 mg of azilsartan (azilsartan, not azilsartan medoxomil, AZ group) once daily for 16 weeks...

BACKGROUND: There is inconclusive evidence about the role of sex as a risk factor for doxorubicin (DOX)-induced cardiotoxicity. Recent experimental studies have shown that adult female rats are protected against DOX-induced cardiotoxicity. However, the mechanisms of this sexual dimorphism are not fully elucidated. We have previously demonstrated that DOX alters the expression of several cytochrome P450 (CYP) enzymes in the hearts of male rats. Nevertheless, the sex-dependent effect of DOX on the expression of CYP enzymes is still not known...
