The dysfunctional nature of CD34 cells from heart failure (HF) patients makes them unsuitable for autologous stem cell therapy. In view of evidence that the vasoprotective axis of the renin-angiotensin system (RAS) improves CD34 cell functions, we hypothesized that CD34 cells from HF patients will be dysfunctional and that Angiotensin-(1-7) [Ang-(1-7)] would improve their function. Peripheral blood was collected from NYHA class II-IV HF patients (n=31) and reference subjects (n=16). CD34 cell numbers from HF patients were reduced by 47% (p<0...

The goal of this study was to measure arterial amino acid levels in patients with chronic heart failure (CHF), and relate them to left ventricular function and disease severity. Amino acids (AAs) play a crucial role for heart protein-energy metabolism. In heart failure, arterial AAs, which are the major determinant of AA uptake by the myocardium, are rarely measured. Forty-one subjects with clinically stable CHF (New York Heart Association (NYHA) class II to IV) were analyzed. After overnight fasting, blood samples from the radial artery were taken to measure AA concentrations...

OBJECTIVES: This study deals clinical and echocardiographic outcomes in cardiac resynchronization therapy (CRT) non-responders patients undergoing Mitraclip procedure. BACKGROUND: Functional mitral regurgitation (FMR) occurs in approximately one-third of heart failure (HF) patients. Resynchronization therapy may correct FMR in patients with HF, however significant FMR persists in 20-25% of CRT patients. METHODS: All patients included were previously treated with CRT for at least 6 months and remained classified as New York Heart Association (NYHA) functional class III or IV despite optimal medical therapy; the echocardiographic assessment showed lack of decrease of the left ventricular end systolic volume (LVESV) of at least 10% and residual moderate-to-severe or severe FMR...

BACKGROUND: Blockade of the renin-angiotensin system (RAS) represents a main strategy in the therapy of heart failure with reduced ejection fraction (HFrEF), but the role of active renin concentration (ARC) for guiding therapy in the presence of an RAS blockade remains to be established. This study assessed angiotensin profiles of HFrEF patients with distinct RAS activations as reflected by ARC. METHODS: Two cohorts of stable chronic HFrEF patients on optimal medical treatment (OMT) were enrolled...

BACKGROUND: Alcohol septal ablation (ASA), is a well-established treatment for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). We report the acute, short and long-term clinical and echocardiographic outcomes of our experience in a single Australian centre over 16 years. METHODS: We retrospectively analysed consecutive patients presenting to our centre for ASA between March 2000 and July 2016. Local databases were interrogated along with direct patient or physician contact occurred where required...

BACKGROUND: Sacubitril/valsartan (LCZ696) is an angiotensin receptor neprilysin inhibitor approved for the treatment of adult heart failure (HF); however, the benefit of sacubitril/valsartan in pediatric HF patients is unknown. STUDY DESIGN: This global multi-center study will use an adaptive, seamless two-part design. Part 1 will assess the pharmacokinetics/pharmacodynamics of single ascending doses of sacubitril/valsartan in pediatric (1 month to <18 years) HF patients with systemic left ventricle and reduced left ventricular systolic function stratified into 3 age groups (Group 1: 6 to <18 years; Group 2: 1 to <6 years; Group 3: 1 month to <1 year)...

A 77 year old man with a biventricular ICD-pacemaker complained of painful, electric jolts disturbing him nightly from sleep. Extensive work-up including device interrogation revealed no defibrillations or arrhythmia, and he was subsequently diagnosed with phantom shocks (PS). His nightly PS symptoms terminated after starting zolpidem 10 mg each night. To date, literature review reveals fifteen articles reporting 163 phantom shock (PS) cases. PS affects 5-9% of ICD recipients. Risk factors include psychiatric disease, atrial fibrillation, NYHA functional status III or greater, prior shock storm, and intraoperative awareness during ICD placement, with defibrillation threshold testing...

We report the first patient experiences with the CardioMEMS device in the Erasmus MC Thorax Center in the Netherlands. In line with clinical trial evidence, the device is applicable in patients with chronic heart failure in functional New York Heart Association class III with at least 1 admission for heart failure in the past 12 months. CardioMEMS has been shown to be safe and reliable, and effective in reducing the number of hospitalisations for heart failure by guided therapy based on pulmonary artery pressures...

BACKGROUND: The diagnosis of heart failure (HF) remains difficult. A wide variety of studies have indicated that microRNAs play important roles in the pathophysiology of HF. HYPOTHESIS: Circulating miRNAs may be the potential biomarkers for HF. METHODS: In this study, a genome-wide plasma miRNA expression analysis was performed in thirteen HF patients and three controls. Microarray was used for the initial screen, followed by validation with quantitative real-time PCR (qRT-PCR) assays in an independent cohort of thirty-three HF patients and twenty controls...

BACKGROUND: Aortic valve stenosis is the most common valvular disease in the elderly. Transcatheter aortic valve implantation represents a viable alternative to conventional aortic valve replacement. In our Department, the transapical approach is the preferred method in patients with severe peripheral vascular disease. The aim of this study was to analyze the early and midterm results of Symetis Acurate TA implantation in our series. METHODS: From June 2013 to January 2017, 21 patients with severe peripheral vascular disease (11 male, mean age 78 ± 2...

OBJECTIVE: Although heart failure (HF) is the leading cause of premature death in adult congenital heart disease (ACHD), little population-specific data exist. This study reports early experience from a dedicated, sub-specialty adult congenital heart disease-heart failure (ACHD-HF) clinic, aiming to identify risk factors for adverse outcome. METHODS: Between 2012 and 2015, 126 patients (57% male) attended the ACHD-HF clinic. Baseline and follow-up data were analysed and compared across 4 anatomical/physiological subgroups: cyanotic ACHD, Fontan circulation (1V), biventricular circulation with a subaortic right ventricle (2V-RV) and biventricular circulation with a subaortic left ventricle (2V-LV)...

BACKGROUND: Heart transplantation (HTx) is the standard treatment for end-stage cardiomyopathy and coronary artery disease. Although major improvements have been made in the prevention and treatment of acute graft rejection, comorbidities still limit the long-term survival of heart transplant recipients. The risk of poor outcome, such us major health status aggravation and death, can stimulate the occurrence of depression and stress in this population. The aim of this study was to determine the impact of comorbidities on depressive symptoms and distress among heart transplant recipients...

This study investigated the association of microstructural cerebral lesions with central sleep apnea with Cheyne-Stokes-respiration (CSA-CSR) in heart failure (HF) patients and the effect of positive airway pressure therapy (PAP) of CSA-CSR on these lesions. PAP-therapy was initiated in patients with HF with midrange and with reduced ejection fraction (NYHA≥II; left ventricular ejection fraction <50%) and proven CSA-CSR. Cerebral magnetic resonance imaging (MRI) scans at 3T including diffusion tensor imaging were obtained before and after 4 months of PAP-therapy...
