This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

BACKGROUND: Subclinical left ventricular (LV) dysfunction has been inconsistently associated with early cognitive impairment, and mechanistic pathways have been poorly considered. We investigated the cross-sectional relationship between LV dysfunction and structural/functional measures of the brain and explored the role of potential mechanisms. METHOD AND RESULTS: A total of 1338 individuals (69±6 years) from the Southall and Brent Revisited study underwent echocardiography for systolic (tissue Doppler imaging peak systolic wave) and diastolic (left atrial diameter) assessment...

Clinical studies have shown that assessing circulating concentrations of high-density lipoprotein (HDL) particles by nuclear magnetic resonance (NMR) spectroscopy is superior to HDL-cholesterol in predicting cardiovascular risk. We tested the hypothesis that circulating concentrations of HDL particles predict 3-month mortality of patients with acute heart failure (AHF). Out of 152 included patients, 52% were female, additionally the mean patient age was 75.2 ± 10.3 years, and three-month mortality was 27%...

The present study was conducted to investigate the effects of salvianolate on perioperative oxidative stress and plasma Intermedin/adrenomedullin 2 (IMD/ADM2) in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). The clinical data of 108 patients with AMI treated by PCI were retrospectively analyzed. According to the use of salvianolate in perioperative period, the patients were divided into the study group (n=62) and the control group (n=46). The control group was given routine treatment while the study group was given routine treatment combined with intravenous infusion of salvianolate (200 mg administered once at 24 h before operation, once/day after operation, 1 week later, the curative effect was observed)...

Metformin is a widely used anti-diabetic drug and increasing evidence suggests that metformin have profound cardioprotective effects under both diabetic and non-diabetic situations. The protective benefits of metformin have been proved in diabetic patients with cardiovascular complications and in experimental animals with myocardial infarction and cardiac hypertrophy. In the present study, we found that treatment with metformin inhibited the cardiac expression of pro-inflammatory cytokines including tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β) and interleukin 6 (IL-6) in endotoxin-challenged mice...

Observational studies suggested a link between bone disease and left ventricular (LV) dysfunction that may be pronounced in hyperparathyroid conditions. We therefore aimed to test the hypothesis that circulating markers of bone turnover correlate with LV function in a cohort of patients with primary hyperparathyroidism (pHPT). Cross-sectional data of 155 subjects with pHPT were analyzed who participated in the "Eplerenone in Primary Hyperparathyroidism" (EPATH) Trial. Multivariate linear regression analyses with LV ejection fraction (LVEF, systolic function) or peak early transmitral filling velocity (e', diastolic function) as dependent variables and N-terminal propeptide of procollagen type 1 (P1NP), osteocalcin (OC), bone-specific alkaline phosphatase (BALP), or beta-crosslaps (CTX) as the respective independent variable were performed...

Chemotherapy of brain glioma faces a major obstacle owing to the inability of drug transport across the blood-brain barrier (BBB). Besides, neovasculatures in brain glioma site result in a rapid infiltration, making complete surgical removal virtually impossible. Herein, we reported a novel kind of C-type natriuretic peptide (CNP) modified vinorelbine lipid vesicles for transferring drug across the BBB, and for treating brain glioma along with disrupting neovasculatures. The studies were performed on brain glioma U87-MG cells in vitro and on glioma-bearing nude mice in vivo...

Background In patients with acute heart failure, early intervention with an intravenous vasodilator has been proposed as a therapeutic goal to reduce cardiac-wall stress and, potentially, myocardial injury, thereby favorably affecting patients' long-term prognosis. Methods In this double-blind trial, we randomly assigned 2157 patients with acute heart failure to receive a continuous intravenous infusion of either ularitide at a dose of 15 ng per kilogram of body weight per minute or matching placebo for 48 hours, in addition to accepted therapy...

Giuseppe Di Tano, Aldo Clerico
A large body of evidence supports the use of natriuretic peptides (brain natriuretic peptide [BNP] and N-terminal proBNP [NT-proBNP]) for the evaluation and management of patients with heart failure over time. Elevated values reflect an enhanced counterregulatory response to hemodynamic stress and are indicative of heart failure severity, thus predicting prognosis. The clinical relevance and result interpretation of natriuretic peptides for monitoring therapy are still debated, and our understanding of their complex nature is still far from being complete...

Objective Excessive activated proinflammatory cytokines may promote extracellular matrix alterations which induce adverse left ventricular remodeling in systolic heart failure (SHF). We sought to identify whether high-sensitivity C-reactive protein (hsCRP) levels were independently associated with SHF. Methods In our retrospective case-control study, 2236 subjects were included, and 260 patients had SHF. Blood sample collection, clinical laboratory tests, electrocardiogram and echocardiography examinations were performed...

BACKGROUND: Patients with acute heart failure (HF) complicated by supraventricular tachyarrhythmia (SVT) often receive continuous intravenous infusion of landiolol or diltiazem for rate control. It is unclear whether the interval from initiation of infusion to commencement of oral beta-blocker (BB) therapy differs for these two drugs. METHODS: From January 2013 to July 2015, 94 consecutive patients were hospitalized for acute HF complicated by SVT. After 35 patients were excluded, the remaining 59 were divided into groups treated with diltiazem or landiolol...

An association between N-terminal prohormone brain natriuretic peptide (NT-proBNP) and exercise tolerance in patients with valvular heart disease (VHD) has been suggested; however, there are few data available regarding this relation. The aim of this study is to evaluate the correlation between exercise tolerance and NT-proBNP in patients with asymptomatic or mildly symptomatic significant VHD and normal left ventricular ejection fraction (LV EF). A total of 96 patients with asymptomatic or mildly symptomatic VHD and normal LV EF (≥50%) underwent cardiopulmonary exercise echocardiography...

The sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin was recently reported to reduce heart failure-associated hospitalizations and cardiovascular mortality amongst individuals with type 2 diabetes at high cardiovascular risk. We sought to elucidate the underlying mechanism(s) for these protective effects using a validated zebrafish heart failure model to evaluate the impact of empagliflozin on the expression of biomarkers of heart failure and mortality. We used aristolochic acid (AA) to induce heart failure in developing cmlc2::GFP transgenic zebrafish embryos and monitored BNP signaling in nppb::Luc transgenic zebrafish with a luciferase reporter assay...
