Inhibition of the Hypoxia-Inducible Factor 1α-Induced Cardiospecific HERNA1 Enhance-Templated RNA Protects From Heart Disease.

Background: Enhancers are genomic regulatory elements conferring spatiotemporal and signal-dependent control of gene expression. Recent evidence suggests that enhancers can generate noncoding enhancer RNAs, but their (patho)biological functions remain largely elusive.

Methods: We performed chromatin immunoprecipitation-coupled sequencing of histone marks combined with RNA sequencing of left ventricular biopsies from experimental and genetic mouse models of human cardiac hypertrophy to identify transcripts revealing enhancer localization, conservation with the human genome, and hypoxia-inducible factor 1α dependence.

Anti-ß1-Adrenoreceptor auto-Antibodies in elderly heart failure patients.

An autoimmune reaction directed against the cardiac b1-adrenergic receptor (beta1-ADR) leading to the generation of autoantibodies (AA) against this G-coupled receptor has been described in patients with heart failure (HF). Agonist-like beta1-ADR-AA are associated with morbidity in HF patients and even predict mortality. Standardised and valid diagnostic tools to detect beta 1-ADR-AA in clinical routine are lacking.

Cystic echinococcosis in unaccompanied minor refugees from Afghanistan and the Middle East to Germany, July 2016 through June 2017.

Cystic echinococcosis (CE) is not covered by current refugee screening protocols. After we had detected CE among several refugees attending our clinic from Afghanistan and the Middle East, serological examinations for CE were performed for apparently healthy unaccompanied minor refugees from these regions.

Sex-specific regulation of cardiac microRNAs targeting mitochondrial proteins in pressure overload.

Background: Maladaptive remodeling in pressure overload (PO)-induced left ventricular hypertrophy (LVH) may lead to heart failure. Major sex differences have been reported in this process. The steroid hormone 17β-estradiol, along with its receptors ERα and ERβ, is thought to be crucial for sex differences and is expected to be protective, but this may not hold true for males.

LDL triglycerides, hepatic lipase activity, and coronary artery disease: An epidemiologic and Mendelian randomization study.

Background And Aims: High concentrations of low density lipoprotein (LDL) triglycerides have been associated with prevalent angiographic coronary artery disease. The present analysis was designed to investigate the association of LDL triglycerides with cardiovascular mortality and to explore possible mechanisms that may link LDL triglycerides to cardiovascular risk.

Methods: LDL triglycerides were measured in 3140 participants of the Ludwigshafen Risk and Cardiovascular Health (LURIC) study.

Impact of Secukinumab on Endothelial Dysfunction and Other Cardiovascular Disease Parameters in Psoriasis Patients over 52 Weeks.

Psoriasis increases the risk of cardiovascular (CV) disease. Secukinumab, a fully human monoclonal antibody against IL-17A, shows significant efficacy in psoriasis, but effects on CV markers are unknown. CARIMA (Evaluation of Cardiovascular Risk Markers in Psoriasis Patients Treated with Secukinumab) was a 52-week, randomized, double-blind, placebo-controlled, exploratory trial in patients with moderate to severe plaque psoriasis without clinical CV disease.

The functional consequences of sodium channel Na 1.8 in human left ventricular hypertrophy.

Aims: In hypertrophy and heart failure, the proarrhythmic persistent Na current (I ) is enhanced. We aimed to investigate the electrophysiological role of neuronal sodium channel Na 1.8 in human hypertrophied myocardium.

Randomized double-blind clinical studies of ularitide and other vasoactive substances in acute decompensated heart failure: a systematic review and meta-analysis.

Aims: Acute decompensated heart failure (ADHF) has a poor prognosis and limited treatment options. No direct comparisons between ularitide-a synthetic natriuretic peptide being evaluated in ADHF-and other vasoactive substances are available. The aim of this meta-analysis was to determine haemodynamic effect sizes from randomized double-blind trials in ADHF.

Assessment of omega-3 carboxylic acids in statin-treated patients with high levels of triglycerides and low levels of high-density lipoprotein cholesterol: Rationale and design of the STRENGTH trial.

It is uncertain whether omega-3 fatty acids are beneficial in statin-treated patients. Epanova is a mix of omega-3 free fatty acids, not requiring co-ingestion with food, which can lower triglycerides by up to 31%. STRENGTH will examine whether Epanova 4 g daily reduces the rate of cardiovascular events in statin-treated patients with hypertriglyceridemia and low levels of HDL-C at high risk for developing cardiovascular events.

Etidronate prevents dystrophic cardiac calcification by inhibiting macrophage aggregation.

Cardiovascular calcification is associated with high risk of vascular disease. This involves macrophage infiltration of injured vascular tissue and osteoclast-related processes. Splenic monocytes from mice, that are predisposed (C3H) or resistant (B6) to calcification, were isolated and differentiated in vitro with M-CSF to generate macrophages, which aggregate to form multinucleated (MN) cells in the presence of RANKL.

Impact of treatment delay on mortality in ST-segment elevation myocardial infarction (STEMI) patients presenting with and without haemodynamic instability: results from the German prospective, multicentre FITT-STEMI trial.

Aims: The aim of this study was to investigate the effect of contact-to-balloon time on mortality in ST-segment elevation myocardial infarction (STEMI) patients with and without haemodynamic instability.

Methods And Results: Using data from the prospective, multicentre Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) trial, we assessed the prognostic relevance of first medical contact-to-balloon time in n = 12 675 STEMI patients who used emergency medical service transportation and were treated with primary percutaneous coronary intervention (PCI). Patients were stratified by cardiogenic shock (CS) and out-of-hospital cardiac arrest (OHCA).

Clinical Impact of Rest Dual-energy Computed Tomography Myocardial Perfusion in Patients with Coronary Artery Disease.

Background/aim: To evaluate the hypothesis that patients with suspected coronary artery disease (CAD) assessed using rest dual-energy computed tomography-derived myocardial perfusion imaging (DECT-P), could have fewer invasive coronary angiographies (ICA), showing non-obstructive CAD.

Materials And Methods: Patients who had undergone coronary computed tomography angiography (cCTA), rest DECT-P and ICA were analyzed.

Results: We evaluated 51 patients (62.

Bedside implantation of a new temporary vena cava inferior filter - Safety and efficacy results of the European ANGEL-Registry.

Purpose: Pulmonary embolism (PE) is a frequently occurring complication in critically ill patients. Simultaneous occurrence of PE and life-threatening bleeding, may render medical anticoagulation impossible. For these patients, inferior vena cava filters (IVCF) present a valuable therapeutic alternative.

High-Density Lipoprotein Subclasses, Coronary Artery Disease, and Cardiovascular Mortality.

Background: The inverse relationship between HDL cholesterol and cardiovascular mortality is weakened in coronary artery disease (CAD). We aimed to investigate the associations of HDL particle concentrations with cardiovascular mortality and the impact of CAD on these associations. We also sought to comparatively evaluate HDL cholesterol and HDL particle concentrations in predicting cardiovascular mortality.

Calcium Signaling and Transcriptional Regulation in Cardiomyocytes.

Calcium (Ca) is a universal regulator of various cellular functions. In cardiomyocytes, Ca is the central element of excitation-contraction coupling, but also impacts diverse signaling cascades and influences the regulation of gene expression, referred to as excitation-transcription coupling. Disturbances in cellular Ca-handling and alterations in Ca-dependent gene expression patterns are pivotal characteristics of failing cardiomyocytes, with several excitation-transcription coupling pathways shown to be critically involved in structural and functional remodeling processes.

Mechanical Activation of Hypoxia-Inducible Factor 1α Drives Endothelial Dysfunction at Atheroprone Sites.

Objective: Atherosclerosis develops near branches and bends of arteries that are exposed to low shear stress (mechanical drag). These sites are characterized by excessive endothelial cell (EC) proliferation and inflammation that promote lesion initiation. The transcription factor HIF1α (hypoxia-inducible factor 1α) is canonically activated by hypoxia and has a role in plaque neovascularization.

Heart failure awareness survey in Germany: general knowledge on heart failure remains poor.

Aims: Previous studies demonstrated poor public awareness of heart failure (HF) compared with myocardial infarction and stroke. With respect to several activities to improve HF awareness in recent years, we present data on the development of HF awareness and information sources in Germany over 8 years.

Methods And Results: In 2007, 2012, and 2015, respectively, 2531, 359, and 171 respondents answered questions about causes, presentation, prognosis, and treatment of HF from a survey developed by the German Competence Network HF.
