Aims: Eisenmenger syndrome (ES) is associated with considerable morbidity and mortality. Therapeutic strategies have changed during the 2000s in conjunction with an emphasis on specialist follow-up. The aim of this study was to determine the cause-specific mortality in ES and evaluate any relevant changes between 1977 and 2015. Methods and results: This is a retrospective, descriptive multicentre study. A total of 1546 patients (mean age 38.7 ± 15.4 years; 36% male) from 13 countries were included...

Patients with refractory leukemia or minimal residual disease (MRD) at transplant have increased risk of relapse. Augmentation of irradiation, especially to sites of disease (i.e., bone marrow) is one potential strategy to overcome this risk. We studied the feasibility of radiation dose escalation in high risk patients using total marrow irradiation (TMI) in a phase I dose-escalation trial. Four pediatric and 8 adult patients received conditioning with cyclophosphamide and fludarabine in conjunction with image-guided radiation to the bone marrow at 15 Gy and 18 Gy (in 3 Gy/fractions), while maintaining the total body irradiation (TBI) dose to the vital organs (lungs, hearts, eyes, liver, kidneys) at <13...

BACKGROUND: Circulating adiponectin concentration increases in patients with chronic heart failure (HF). We sought to explore the prognostic value of temporal changes in adiponectin concentration following treatment for chronic HF. METHODS: Serum adiponectin levels were measured at baseline and after a 3-month anti-failure treatment in 124 patients with symptomatic chronic systolic HF. Major adverse cardiac events (MACE) including death, heart transplantation, or hospitalization with worsening HF during a median follow-up period of 752 days were determined...

Broiler hens consuming feed to appetite (ad libitum; AL) show increased mortality. Feed restriction (R) typically improves reproductive performance and livability of hens. Rapidly growing broilers can exhibit increased mortality due to cardiac insufficiency but it is unknown whether the increased mortality of non-R broiler hens is also due to cardiac compromise. To assess cardiac growth and physiology in fully mature birds, 45-week-old hens were either continued on R rations or assigned to AL feeding for 7 or 21 days...

Sacubitril/valsartan (LCZ696) is the first angiotensin receptor neprilysin inhibitor approved to reduce cardiovascular mortality and hospitalization in patients with heart failure with reduced ejection fraction. As neprilysin (NEP) is one of several enzymes known to degrade amyloid-β (Aβ), there is a theoretical risk of Aβ accumulation following long-term NEP inhibition. The primary objective of this study was to evaluate the potential effects of sacubitril/valsartan on central nervous system clearance of Aβ isoforms in cynomolgus monkeys using the sensitive Stable Isotope Labeling Kinetics (SILK™)-Aβ methodology...

The Cardiovascular Disease in Women Committee of the American College of Cardiology, in conjunction with interested parties (from the National Heart, Lung, and Blood Institute, American Heart Association, and European Society of Cardiology), convened a working group to develop a consensus on the syndrome of myocardial ischemia with no obstructive coronary arteries. In general, these patients have elevated risk for a cardiovascular event (including acute coronary syndrome, heart failure hospitalization, stroke, and repeat cardiovascular procedures) compared with reference subjects and appear to be at higher risk for development of heart failure with preserved ejection fraction...

Sacubitril/valsartan combines a neprilysin inhibitor with an angiotensin receptor blocker. As an inhibitor of neprilysin, an enzyme that degrades biologically active natriuretic peptides, this first-in-class therapy increases levels of circulating natriuretic peptides, resulting in natriuretic, diuretic, and vasodilatory effects. In patients with chronic New York Heart Association class II-IV heart failure with reduced ejection fraction, the PARADIGM-HF trial demonstrated that sacubitril/valsartan significantly reduced the primary endpoint of cardiovascular mortality and heart failure hospitalization, compared with enalapril...

Myocardial stiffness is a valuable clinical biomarker for the monitoring and stratification of heart failure (HF). Cardiac finite element models provide a biomechanical framework for the assessment of stiffness through the determination of the myocardial constitutive model parameters. The reported parameter intercorrelations in popular constitutive relations, however, obstruct the unique estimation of material parameters and limit the reliable translation of this stiffness metric to clinical practice. Focusing on the role of the cost function (CF) in parameter identifiability, we investigate the performance of a set of geometric indices (based on displacements, strains, cavity volume, wall thickness and apicobasal dimension of the ventricle) and a novel CF derived from energy conservation...

To manage myocardial recovery in patients with the HeartWare left ventricular assist device (HVAD), we describe a minimally invasive approach ('decommissioning') that involves disconnecting the driveline and occluding the outflow tract through a small left thoracotomy incision leaving the device in situ, in conjunction with optimal medical therapies and comprehensive assessment of left ventricular recovery. Nine patients (all male, 37 ± 12 years, all non-ischemic dilated cardiomyopathy) had an HVAD implanted for 766±343 days...

Treating to target by monitoring disease activity and adjusting therapy to attain remission or low disease activity has been shown to lead to improved outcomes in chronic rheumatic diseases such as rheumatoid arthritis and spondyloarthritis. Patient-reported outcomes, used in conjunction with clinical measures, add an important perspective of disease activity as perceived by the patient. Several validated PROs are available for inflammatory arthritis, and advances in electronic patient monitoring tools are helping patients with chronic diseases to self-monitor and assess their symptoms and health...

Myocardial infarction is one of the leading causes of cardiac dysfunction, failure and sudden death. Post infarction cardiac remodeling presents a poor prognosis, with 30%-45% of patients developing heart failure, in a period of 5-25years. Oxidative stress has been labelled as the primary causative factor for cardiac damage during infarction, however, the impact it may have during the process of post infarction remodeling has not been well probed. In this study, we have implemented iTRAQ proteomics to catalogue proteins and functional processes, participating both temporally (early and late phases) and spatially (infarct and remote zones), during post myocardial infarction remodeling of the heart as functions of the differential oxidative stress manifest during the remodeling process...

Duchenne muscular dystrophy (DMD) is an incurable X-linked genetic disease that is caused by a mutation in the dystrophin gene and affects one in every 3,600 boys. We previously showed that long telomeres protect mice from the lethal cardiac disease seen in humans with the same genetic defect, dystrophin deficiency. By generating the mdx(4cv)/mTR(G2) mouse model with "humanized" telomere lengths, the devastating dilated cardiomyopathy phenotype seen in patients with DMD was recapitulated. Here, we analyze the degenerative sequelae that culminate in heart failure and death in this mouse model...

South Africa and other areas of sub-Saharan Africa have in the past 20 years undergone rapid demographical changes, largely due to urbanisation and changes in lifestyle. This rapid change has led to a marked increase in specific cardiac conditions, such as hypertensive heart disease and coronary artery disease (with the highest prevalence in the middle-aged population), in conjunction with a range of other heart diseases, which are historically common in Africa-eg, rheumatic heart disease, cardiomyopathies, and unoperated congenital heart disease...

INTRODUCTION: Remote patient monitoring (RPM) in conjunction with home nursing visits is becoming increasingly popular for the follow-up of patients with chronic conditions and evidence exists that it improves patients' health outcomes. Current cost data is reported inconsistently and often gathered from studies of poor methodological quality, making it difficult for decision-makers who consider implementing this service in their organizations. This study reviewed the cost of RPM programmes targeting elderly patients with chronic conditions...

Secreted Frizzled-related protein 2 (sFRP2) plays a key role in chronic fibrosis after myocardial infarction and in heart failure. The aim of this study was to elucidate the mechanisms through which sFRP2 may regulate the growth and extracellular matrix (ECM) remodeling of adult mouse cardiac fibroblasts (CFs). We found that sFRP2 activates CFs in part through canonical Wnt/β-catenin signaling, as evidenced by increased expression of Axin2 and Wnt3a, but not Wnt5a, as well as accumulation of nuclear β-catenin...

Concentric left ventricular hypertrophy (LVH) is a hallmark finding in hypertrophic cardiomyopathy that leads to diastolic dysfunction and variable cardiac consequences as severe as congestive heart failure and sudden cardiac death. LVH was diagnosed postmortem in a large colony of rhesus macaques (Macaca mulatta), but methods to screen and diagnose LVH in living animals are desired. We hypothesized that targeted echocardiography of macaques with a familial association of LVH would yield antemortem LVH diagnoses...
