BACKGROUND: Metabolic profiles have been shown to provide prognostic information in patients with heart failure (HF). Galectin-3 (Gal-3), indicating cardiac fibrosis, is a documented biomarker of prognosis in HF. It is unknown whether metabolic profiles provide prognostic value better than Gal-3. METHODS AND RESULTS: This study analyzed 212 hospitalized HF patients, measuring metabolic score (composed by butyrylcarnitine, dimethylarginine/arginine ratio, spermidine, and total essential amino acids) and Gal-3...

Sustained cardiac hypertrophy (CH) is related to a variety of physiological as well as pathological stimuli and eventually increases the risk of heart failure. HOTAIR has been identified as a competing endogenous RNA in multiple human biological processes. Whether lncRNA-HOTAIR is involved in the progress of CH and how it works still remain unknown. Herein, we found that HOTAIR was down-regulated, while miR-19 was up-regulated in both heart tissues from TAC-operated mice in vivo and cultural cardiomyocytes treated with Ang-II in vitro by real-time PCR...

REVIEW
Samy Talha, Anne Charloux, François Piquard, Bernard Geny
Heart transplantation (HT) should normalize cardiac endocrine function but brain natriuretic peptide (BNP) levels remain elevated after HT, even in the absence of left ventricular haemodynamic disturbance or allograft rejection. Right ventricle (RV) abnormalities are common in HT recipients (HTx), as a result of engraftment process, tricuspid insufficiency and/or repeated inflammation due to iterative endomyocardial biopsies. RV function follow-up is vital for patient management since RV dysfunction is a recognized cause of in-hospital death and is responsible for a worse prognosis...

The adult heart retains a limited ability to regenerate in response to injury. Although exercise can reduce cardiac ischaemia/reperfusion (I/R) injury, the relative contribution of cardiac cell proliferation including newly formed cardiomyocytes remains unclear. A 4-week swimming murine model was utilized to induce cardiac physiological growth. Simultaneously, the antineoplastic agent 5-fluorouracil (5-FU), which acts during the S phase of the cell cycle, was given to mice via intraperitoneal injections. Using EdU and Ki-67 immunolabelling, we showed that exercise-induced cardiac cell proliferation was blunted by 5-FU...

OBJECTIVE: Plasma concentrations of B-type natriuretic peptide (BNP) and troponin are often measured for diagnostic purposes when patients are admitted with heart failure, but their prognostic value when measured soon after admission is uncertain. We aimed to investigate the added prognostic value of admission measurements of BNP and troponins in patients with acute heart failure. METHODS AND RESULTS: Multivariable prognostic models for death or any worsening heart failure (WHF) or rehospitalization for WHF by 30 days, 30-day death or rehospitalization for WHF, and 90-day mortality were constructed using baseline data from the Value of Endothelin Receptor Inhibition with Tezosentan in Acute heart failure Studies (VERITAS) including BNP and troponin I...

Cardiac hypertrophy is an early hallmark during the clinical course of heart failure and regulated by various signalling pathways. Recently, we observed that mouse embryonic fibroblasts from CD38 knockout mice were significantly resistant to oxidative stress such as H2 O2 -induced injury and hypoxia/reoxygenation-induced injury. In addition, we also found that CD38 knockout mice protected heart from ischaemia reperfusion injury through activating SIRT1/FOXOs-mediated antioxidative stress pathway. However, the role of CD38 in cardiac hypertrophy is not explored...

Evaluation of myocardial mechanics after heart transplant is important in monitoring allograft function and identifying rejection. Speckle tracking global longitudinal strain (GLS) may be more sensitive to early regional changes from rejection. This study aimed to determine feasibility of GLS in pediatric hearts during surveillance echocardiograms, compare their GLS to published norms (-18% to -22%), and assess association of GLS with other indices of graft function. Retrospective review of transplant echocardiograms from 2013 to 2014...

BACKGROUND: Levels of plasma brain natriuretic peptide (BNP) have been shown to be elevated in chronic obstructive pulmonary disease (COPD) especially in connection with cor pulmonale (CP) and the late stages of the disease. BNP is also raised in left sided heart failure which sometimes coincides with COPD. Whether BNP is elevated in subjects with mild-moderate stable COPD and normal left ventricular function is not clear. OBJECTIVE: To investigate BNP levels in subjects with mild-moderate COPD and normal left ventricular function...

OBJECTIVE: Increased levels of neuro-hormonal biomarkers predict poor prognosis in patients with acute myocardial infarction (AMI) complicated by left ventricular systolic dysfunction (LVSD). The predictive value of repeated (one-month interval) brain natriuretic peptides (BNP) and big-endothelin 1 (BigET-1) measurements were investigated in patients with LVSD after AMI. METHODS: In a sub-study of the Eplerenone Post-Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS trial), BNP and BigET-1 were measured at baseline and at 1month in 476 patients...

BACKGROUND: Percutaneous mitral valve repair (PMVR) using the MitraClip™ system has become a valuable alternative in patients with severe mitral regurgitation (MR) and high surgical risk. We sought to evaluate the prognostic value of the SYNTAX II score (SSII) in patients with concomitant coronary artery disease (CAD) undergoing a Mitraclip procedure. METHODS: In seventy-five consecutive patients who underwent PMVR at the University Heart Center Zürich and the Cardiocentro Ticino, the SSSII was calculated at baseline...

B-type natriuretic peptides are markers of myocardial wall stress. BNP or NT-proBNP are used for the differential diagnosis of acute dyspnoe where normal serum concentrations make a cardiac cause unlikely. New data show their importance for risk prediction in different stages of heart failure and in primary prevention. Natriuretic peptide guided therapy improves titration of heart failure medications. Compared to BNP, NT-proBNP is better suited during therapy with the new angiotensin-rezeptor-neprilysin-inhibitor Sacubitril/Valsartan...

BACKGROUND: Polymorphisms within natriuretic peptide (NP) genes have been associated with clinical outcomes for cardiovascular disease (CVD), but no previous study has compared the effect of these polymorphisms between men and women. This study aimed to investigate the association between single nucleotide polymorphisms (SNPs) in key genes of the NP system and coronary angiographic outcomes, with the focus on the sexual dimorphism in the effects of these SNPs. METHODS: Patients undergoing clinically indicated coronary angiography (n = 513, 328 men and 185 women) were consented and genotyped for NPPA rs5065, NPPB rs198389 and NPR2 rs10758325...

AIM: Chronic hypoxia leads to right ventricular hypertrophy (RVH). RVH is believed to result from hypoxia-induced pulmonary hypertension. However, if hypoxia impacts RVH directly awaits clarification. Hypoxia triggers oxidative stress, and lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) mediates reactive oxygen species (ROS) generation in different cells. Therefore, this study aims to explore whether LOX-1-mediated oxidative stress accounts for hypoxia-induced RVH. MAIN METHODS: Rats developed RVH after 3weeks of hypoxia (10% O2)...

BACKGROUND: The acute favourable effect of balloon pulmonary angioplasty (BPA) has been proven in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, data on its effect 6 months after therapy (from now on referred to as mid-term) and influence on the right ventricle and myocardial damage are sparse. To evaluate factors that influence improvement in cardiac output (CO) and subclinical myocardial damage, we examined hemodynamics and serum high-sensitivity troponin T (hs-TnT) levels before, 1 week after, and 6 months after BPA...
