GLUT transgenic and knockout mice have provided valuable insight into the role of facilitative glucose transporters (GLUTs) in cardiovascular and metabolic disease, but compensatory physiological changes can hinder interpretation of these models. To determine whether adaptations occur in response to GLUT inhibition in the failing adult heart, we chronically treated TG9 mice, a transgenic model of dilated cardiomyopathy and heart failure, with the GLUT inhibitor ritonavir. Glucose tolerance was significantly improved with chronic treatment and correlated with decreased adipose tissue retinol binding protein 4 (RBP4) and resistin...

<u>Rationale:</u> Cardiac fibroblasts do not form a syncytium but reside in the interstitium between myocytes. This topological relationship between fibroblasts and myocytes is maintained throughout post-natal life until acute myocardial injury occurs, when fibroblasts are recruited to, proliferate and aggregate in the region of myocyte necrosis. The accumulation or aggregation of fibroblasts in the area of injury thus represents a unique event in the life cycle of the fibroblast but little is known about how changes in the topological arrangement of fibroblasts following cardiac injury affect fibroblast function...

Heart failure (HF) is a threat to public health. Heterogeneities in etiology and phenotype complicate the diagnosis and management of HF. This is especially true when considering HF with preserved ejection fraction (HFpEF) which make up 50% of HF cases. Natriuretic peptides may aid in establishing a working diagnosis in patients suspected of HF, but echocardiography remains the optimal choice for diagnosing HF. Echocardiography provides important prognostic information in both HF with reduced ejection fraction (HFrEF) and HFpEF...

IntroductionChildren with CHD and acquired heart disease have unique, high-risk physiology. They may have a higher risk of adverse tracheal-intubation-associated events, as compared with children with non-cardiac disease.Materials and methodsWe sought to evaluate the occurrence of adverse tracheal-intubation-associated events in children with cardiac disease compared to children with non-cardiac disease. A retrospective analysis of tracheal intubations from 38 international paediatric ICUs was performed using the National Emergency Airway Registry for Children (NEAR4KIDS) quality improvement registry...

Pathological cardiac hypertrophy and dysfunction is a response to various stress stimuli and can result in reduced cardiac output and heart failure. Cyclic nucleotide signaling regulates several cardiac functions including contractility, remodeling, and fibrosis. Cyclic nucleotide phosphodiesterases (PDEs), by catalyzing the hydrolysis of cyclic nucleotides, are critical in the homeostasis of intracellular cyclic nucleotide signaling and hold great therapeutic potential as drug targets. Recent studies have revealed that the inhibition of the PDE family member PDE1 plays a protective role in pathological cardiac remodeling and dysfunction by the modulation of distinct cyclic nucleotide signaling pathways...

BACKGROUND/AIMS: Percutaneous coronary intervention reduces acute myocardial infarction (MI)-induced mortality to a great extent, but effective treatments for MI-induced cardiac fibrosis and heart failure are still lacking. MicroRNAs (miRNAs) play a variety of roles in cells and have thus been investigated extensively. MicroRNA-223 (miR-223) expression has been reported to be altered in post-MI heart failure in humans; however, the roles of miR-223 in MI remain unknown. Our study aimed to elucidate the roles of miR-223 in cardiac fibrosis...

Aorto-atrial fistulas are a rare diagnosis with limited reports in the clinical literature. These findings are often characterized by echocardiography alone; however, the advent and increased availability and use of CT angiography to diagnose cardiac abnormalities provides improved anatomic visibility of potential defects. We are reporting a case of a 76-year-old male with decompensated heart failure secondary to a fistula between the aorta and left atrium after remote history of bioprosthetic aortic valve replacement...

Adrenomedullin (AM), a member of the calcitonin peptide superfamily, is a peptide involved in both the pathogenesis of cardiovascular diseases and circulatory homeostasis. Its receptor, calcitonin receptor-like receptor (CLR), associates with an accessory protein, receptor activity-modifying protein (RAMP). Depending upon which the three RAMP isoforms (RAMP1-3) it interacts with, CLR functions as a receptor for AM or other calcitonin family peptides. AM knockout mice (-/-) died mid-gestation due to abnormalities in vascular development...

Cerebral tissue oxygen saturation (SctO2) reflects cerebral perfusion and tissue oxygen consumption, which decline in some patients with heart failure with reduced ejection fraction (HFrEF) or stroke, especially during exercise. Its physiologic basis and clinical significance remain unclear. We aimed to investigate the association of SctO2 with oxygen transport physiology and known prognostic factors during both rest and exercise in patients with HFrEF or stroke. Thirty-four HFrEF patients, 26 stroke patients, and 17 healthy controls performed an incremental cardiopulmonary exercise test using a bicycle ergometer...

Oxidative stress contributes to myocardial ischemia-reperfusion injury, which causes cardiomyocyte death and precipitate life-threatening heart failure. Propofol has been proposed to protect cells or tissues against oxidative stress. However, the mechanisms underlying its beneficial effects are not fully elucidated. In the present study, we employed an in vitro oxidative injury model, in which rat cardiac H9c2 cells were treated with H2O2, and investigated roles of propofol against oxidative stress. Propofol treatment reduced H2O2-induced apoptotic cell death...

Heart failure (HF) is one of the leading causes of hospitalization in high-income countries and has a profound negative impact on quality of life. In the United States there are more than 900,000 new cases per year and over one million hospital admissions with a primary diagnosis of HF. A prevalence of 6,500,000 cases (2.2% of the population of aged >20 years) was estimated for the US in 2014, in which there were 300,000 related deaths. Although survival has increased, thanks to the pharmacological and non pharmacological therapy, roughly 50% of HF patients die within 5 years of being diagnosed...

Heart failure is a common adverse effect associated with doxorubicin treatment. The aim of this study is to investigate the effect of ivabradine treatment on doxorubicin-induced heart failure in conscious rats. Rats were treated with doxorubicin (2.5 mg/kg/day) or ivabradine (10 mg/kg/day) alone or along with doxorubicin injections. Changes in heart rate variability (HRV), baroreflex sensitivity, left ventricular function, serum cardiac troponin T and cardiac histological features were taken as index parameters for the development of heart failure...

Background The food environment has been hypothesized to influence cardiovascular diseases such as hypertension and coronary heart disease. This study determines the relation between fast-food outlet density (FFD) and the individual risk for cardiovascular disease, among a nationwide Dutch sample. Methods After linkage of three national registers, a cohort of 2,472,004 adults (≥35 years), free from cardiovascular disease at January 1st 2009 and living at the same address for ≥15 years was constructed. Participants were followed for one year to determine incidence of cardiovascular disease, including coronary heart disease, stroke and heart failure...

Components of the cardiac extracellular matrix (ECM) are synthesized by residing cells and are continuously remodeled by them. Conversely, residing cells (including primitive cells) receive constant biochemical and mechanical signals from the ECM that modulate their biology. The pathological progression of heart failure affects all residing cells, inevitably causing profound changes in ECM composition and architecture that, in turn, impact on cell phenotypes. Any regenerative medicine approach must aim at sustaining microenvironment conditions that favor cardiogenic commitment of therapeutic cells and minimize pro-fibrotic signals, while conversely boosting the capacity of therapeutic cells to counteract adverse remodeling of the ECM...

Aims: Remote monitoring of implantable cardioverter-defibrillators may improve clinical outcome. A recent meta-analysis of three randomized controlled trials (TRUST, ECOST, IN-TIME) using a specific remote monitoring system with daily transmissions [Biotronik Home Monitoring (HM)] demonstrated improved survival. We performed a patient-level analysis to verify this result with appropriate time-to-event statistics and to investigate further clinical endpoints. Methods and results: Individual data of the TRUST, ECOST, and IN-TIME patients were pooled to calculate absolute risks of endpoints at 1-year follow-up for HM vs...

Remodeling of cardiac tissue architecture is essential for normal organ development and maintaining homeostasis after injury. Injurious insults to the heart, such as hypertension and myocardial infarction, promote cellular responses including stimulation of resident inflammatory cells, activation of endothelial cells and recruitment of immune cells, hypertrophy of cardiomyocytes, and activation of fibroblasts. The physiological goal of this coordinated cellular response is to repair damaged tissue while maintaining or restoring cardiac contractile function...
