A 70-year old Caucasian man with recurrent ventricular tachycardia and progressive biventricular failure attributed to arrhythmogenic right ventricular cardiomyopathy/dysplasia was evaluated for heart transplantation. Cardiac ventriculography revealed an abnormal left ventricle with five saccular aneurysms. Heart transplantation was performed. Pathology of the explanted heart showed multifocal sarcoid granulomas. Replacement fibrosis was widespread in both ventricles and associated with saccular aneurysms. No genetic basis was identified...

Aims: Heart failure (HF) is accompanied by major neuroendocrine changes including the activation of the natriuretic peptide (NP) pathway. Using the unique model of patients undergoing implantation of the CARMAT total artificial heart and investigating regional differences in soluble neprilysin (sNEP) in patients with reduced or preserved systolic function, we studied the regulation of the NP pathway in HF. Methods and results: Venous blood samples from two patients undergoing replacement of the failing ventricles with a total artificial heart were collected before implantation and weekly thereafter until post-operative week 6...

Excessive mechanical stretch induces production of proinflammatory mediators in cardiac fibroblasts, which could act as inflammatory supporter cells in heart failure. Accumulation evidence and our previous studies suggest that serum-glucocorticoid-regulated kinase 1 (SGK1) contributes to cardiac remodeling and fibrosis, development of heart failure. However, the role and mechanism of SGK1 in mechanical stretch-induced inflammation of cardiac fibroblasts remain unclear. Here, cardiac fibroblasts isolated from wild-type (WT) and SGK1 knockout (SGK1-/-) mice were stimulated by 18% cyclic stretch, under static condition as the control...

Myocardial infarction leads to an irreversible loss of vital myocardial cells. The transplantation of new cardiomyocytes into the heart was first described over 20 years ago and represents a straightforward approach to remuscularize a damaged heart. Due to the lack of human cells a clinical application seemed ambitious; however, dramatic progress in stem cell biology over the last two decades has paved the way towards a clinical application. This is especially important as the prognosis for patients with terminal heart failure is still poor...

Left ventricular end-diastolic pressure (LVEDP) is an easily obtained, physiologically integrative measure of total LV function. LVEDP may be a useful prognostic measure in patients with acute myocardial infarction and utilised to guide medical therapy and assess risk for post myocardial infarction heart failure. To assess the utility of LVEDP as a prognostic measure in patients presenting with acute myocardial infarction. We performed an unrestricted search of electronic databases (1946 to March 2017) using a predefined search strategy...

Anemia and chronic heart failure are frequent comorbidities in geriatric patients. In approximately one third of older adults the cause of the anemia is an iron, vitamin B12 and/or folate deficiency and in another third a chronic inflammatory process is present. In the case of iron deficiency a differentiation must be made between the absolute and functional forms. Although in functional iron deficiency ferritin, as a parameter of iron metabolism, is within the normal range or can even be higher, an iron-deficient erythropoiesis is present...

BACKGROUND: Energy starvation and the shift of energy substrate from fatty acids to glucose is the hallmark of metabolic remodeling during heart failure progression. However, ketone body metabolism in the failing heart has not been fully investigated. METHODS AND RESULTS: Microarray data analysis and mitochondrial isobaric tags for relative and absolute quantification proteomics revealed that the expression of D-β-hydroxybutyrate dehydrogenase I (Bdh1), an enzyme that catalyzes the NAD+/NADH coupled interconversion of acetoacetate and β-hydroxybutyrate, was increased 2...

BACKGROUND: Risk-prediction models specifically for hospitalized heart failure with preserved ejection fraction are lacking. METHODS AND RESULTS: We analyzed data from the ARIC (Atherosclerosis Risk in Communities) Study Heart Failure Community Surveillance to create and validate a risk score predicting mortality in patients ≥55 years of age admitted with acute decompensated heart failure with preserved ejection fraction (ejection fraction ≥50%). A modified version of the risk-prediction model for acute heart failure developed from patients in the EFFECT (Enhanced Feedback for Effective Cardiac Treatment) study was used as a composite predictor of 28-day and 1-year mortalities and evaluated together with other potential predictors in a stepwise logistic regression...

BACKGROUND: The incidence and clinical significance of persistent T2 hyperintensity after acute ST-segment-elevation myocardial infarction (STEMI) is uncertain. METHODS AND RESULTS: Patients who sustained an acute STEMI were enrolled in a cohort study (BHF MR-MI: NCT02072850). Two hundred eighty-three STEMI patients (mean age, 59±12 years; 75% male) had cardiac magnetic resonance with T2 mapping performed at 2 days and 6 months post-STEMI. Persisting T2 hyperintensity was defined as infarct T2 >2 SDs from remote T2 at 6 months...

BACKGROUND: Estimation of diffuse myocardial fibrosis, substrate for adverse events such as heart failure and arrhythmias in patients with various cardiac disorders, is presently done by histopathology or cardiac magnetic resonance. We sought to develop a non-contrast method to estimate the amount of diffuse myocardial fibrosis leveraging dual energy computed tomography (DECT) in phantoms and a suitable small animal model. METHODS AND RESULTS: Phantoms consisted of homogenized bovine myocardium with varying amounts of Type 1 collagen...

Unraveling the mechanisms underlying Takotsubo (TTS) leads to question the current inclusion of the condition within the spectrum of cardiomyopathies. Indeed, the clinical presentation and pathophysiology of TTS clearly differ from cardiomyopathies, i.e. diseases of heart muscle unexplained by abnormal loading conditions or coronary artery disease, which cannot recover spontaneously and may cause sudden death often in minimally symptomatic individuals or result in a gradual deterioration in ventricular function and end-stage heart failure...

INTRODUCTION: Compared with coronary heart disease and stroke, the association between SES and the risk of heart failure is less well understood. METHODS: In 12,646 participants of the Atherosclerosis Risk in Communities Study cohort free of heart failure history at baseline (1987-1989), the association of income, educational attainment, and area deprivation index with subsequent heart failure-related hospitalization or death was examined while accounting for cardiovascular disease risk factors and healthcare access...

Cardiovascular disease (CVD) is a key cause of deaths worldwide, comprising 15-17% of healthcare expenditure in developed countries. Current records estimate an annual global average of 30 million cardiac dysfunction cases, with a predicted escalation by two-three folds for the next 20-30years. Although β-blockers and angiotensin-converting-enzymes are commonly prescribed to control CVD risk, hepatotoxicity and hematological changes are frequent adverse events associated with these drugs. Search for alternatives identified endogenous cofactor l-carnitine, which is capable of promoting mitochondrial β-oxidation towards a balanced cardiac energy metabolism...

BACKGROUND: Severe isolated disease of the tricuspid valve (TV) is increasing and results in intractable right heart failure. However, isolated TV surgery is rarely performed, and there are little data describing surgical outcomes. OBJECTIVES: The purpose of this study was to evaluate contemporary utilization trends and in-hospital outcomes for isolated TV surgery in the United States. METHODS: Patients age >18 years who underwent TV repair or replacement from 2004 to 2013 were identified using the National Inpatient Sample...

Pathological cardiac hypertrophy is the main determinant of the development of heart failure, for which there is often no effective therapy. The dysregulation of autophagy is implicated in hypertrophy, but the mechanism linking these processes is unclear. In this study, we characterized the regulatory role of miR-208a-3p in autophagy in H9c2 cardiomyoblasts induced by Angiotensin II (Ang II). We found that miR-208a-3p was up-regulated in Ang II-induced H9c2 cardiomyoblasts and in starvation-induced autophagy...

Dilated cardiomyopathy (DCM) is the major cause of heart failure affecting both women and men. Limited clinical studies show conflicting data in sex-related differences in the progression of dilated cardiomyopathy and heart failure (HF) outcomes. We examined the comparative sex-related progression of cardiomyopathy and the development of HF (at 4, 7, 13 weeks of age) in a well-established, transgenic mouse model of DCM that recapitulates the progressive stages of human HF. By 13 weeks of age, female mice with DCM had more severe left ventricular systolic dysfunction, left ventricular dilation and wall thinning (P<0...

INTRODUCTION: The bidirectional Glenn operation for congenital heart disease produces anatomical constraints to conventional transvenous pacemaker implantation. An iliac approach, although not previously described in this population, is potentially a preferable alternative to a thoracotomy for epicardial pacing. METHODS AND RESULTS: A single-center retrospective review was performed for all patients that underwent transvenous pacemaker implantation following the bidirectional Glenn operation with partial biventricular repair...
