AIMS: Non-coding microRNAs (miRNAs) are critically involved in cardiovascular pathophysiology. Since they are measurable in most body fluids, they have been proposed as circulating biomarkers. We examined the prognostic value of a specific candidate miRNA in a large cohort of patients with chronic heart failure (HF) enrolled in a multicentre clinical trial. METHODS AND RESULTS: Plasma levels of miR-132 were measured using miRNA-specific PCR-based technologies at randomization in 953 patients with chronic, symptomatic HF from the GISSI-Heart Failure trial...

BACKGROUND: Cardiac troponin I (cTnI) is a valuable prognostic biomarker in patients with chronic heart failure (CHF). However, the prognostic importance of cTnI in patients who received cardiac resynchronisation therapy (CRT) remains unknown. The aim of this prospective study was to determine the prognostic value of high-sensitive cTnI (hs-cTnI) in CHF patients receiving CRT. METHODS: We performed measurements of baseline hs-cTnI levels in CRT patients with ischaemic as well as nonischaemic aetiology of CHF, and we investigated their possible association with response to CRT and survival of patients...

OBJECTIVE: To investigate the associations between age, vascular health, and Alzheimer's disease (AD) imaging biomarkers in an elderly sample. METHODS: We identified 430 individuals along the cognitive continuum aged>60 years with amyloid-PET, Tau-PET, and MRI scans from the population-based Mayo Clinic Study of Aging. A subset of 329 individuals had FDG-PET. We ascertained presently existing cardiovascular and metabolic conditions (CMC) from healthcare records and used the summation of presence/absence of hypertension, hyperlipidemia, cardiac-arrhythmias, coronary artery disease, congestive heart failure, diabetes mellitus, and stroke as a surrogate for vascular health...

Heart failure is a major health problem linked to poor quality of life and high mortality rates. Hence, novel biomarkers, such as fetal marker genes with low expression levels, could potentially differentiate disease states in order to improve therapy. In many studies on heart failure, cardiac biopsies have been analyzed as uniform pieces of tissue with bulk techniques, but this homogenization approach can mask medically relevant phenotypes occurring only in isolated parts of the tissue. This study examines such spatial variations within and between regions of cardiac biopsies...

The objective of this paper is development of an inexpensive point-of-care sensor for detecting the primary heart failure marker peptide, NT-proBNP. The device technology is based on an antibody sandwich assay, but with three innovative aspects. First, chemical amplification is carried out via oxidation of silver nanoparticles (NPs) attached to signaling antibodies rather than by enzymatic amplification. The electrochemical method is faster and eliminates the need for long-term storage of enzymes. Second, the antibody sandwich is formed on mobile magnetic beads...

BACKGROUND: Hemodynamic balance in the heart-brain axis is increasingly recognized as a crucial factor in maintaining functional and structural integrity of the brain and thereby cognitive functioning. Patients with heart failure (HF), carotid occlusive disease (COD), and vascular cognitive impairment (VCI) present themselves with complaints attributed to specific parts of the heart-brain axis, but hemodynamic changes often go beyond the part of the axis for which they primarily seek medical advice...

Cyclophilin A (CyPA) is secreted from vascular smooth muscle cells, inflammatory cells, activated platelets, and cardiac fibroblasts in response to oxidative stress. Excessive and continuous activation of the RhoA/Rho-kinase system promotes the secretion of CyPA, resulting in the development of multiple cardiovascular diseases. Basigin (Bsg), a transmembrane glycoprotein that activates matrix metalloproteinases, is an extracellular receptor for CyPA that promotes cell proliferation and inflammation. Thus, the CyPA/Bsg system is potentially a novel therapeutic target for cardiovascular diseases...

In recent years, vascular depression has become the focus of international attention. Yangxinshi Tablet (YXST) is usually used in clinic for treatment of arrhythmia and heart failure, but we found that it also has anti-depressive effect in this study. The objective of the study was to identify biomarkers related to vascular depression in hippocampus and explore the anti-depressive effects of YXST on the mice model. Untargeted metabolomics based on UHPLC-Q-TOF/MS was applied to identify significant differential biomarkers between model group and control group...

AIMS: Myocardial fibrosis alters the cardiac architecture favouring the development of cardiac dysfunction, including arrhythmias and heart failure. Reducing myocardial fibrosis may improve outcomes through the targeted diagnosis and treatment of emerging fibrotic pathways. The European-Commission-funded 'FIBROTARGETS' is a multinational academic and industrial consortium with the main aims of (i) characterizing novel key mechanistic pathways involved in the metabolism of fibrillary collagen that may serve as biotargets, (ii) evaluating the potential anti-fibrotic properties of novel or repurposed molecules interfering with the newly identified biotargets, and (iii) characterizing bioprofiles based on distinct mechanistic phenotypes involving the aforementioned biotargets...

The troponin complex consists of three proteins that fundamentally couple excitation with contraction. Circulating cardiac-specific Troponin I (cTnI) serves as diagnostic biomarker tools for risk stratification of acute coronary syndromes and acute myocardial infarction (MI). Within the heart, cTnI oscillates between inactive and active conformations to either block or disinhibit actinomyosin formation. This molecular mechanism is fine-tuned through extensive protein modifications whose profiles are maladaptively altered with co-morbidities including hypertrophic cardiomyopathy, diabetes, and heart failure...

INTRODUCTION: Blood biomarkers have the potential to monitor the severity of chronic heart failure (CHF). Studies correlating repeated measurements of blood biomarkers with repeatedly assessed New York Heart Association (NYHA) class over a prolonged follow-up period, and concomitantly investigating their associations with clinical endpoints, have not yet been performed. METHODS: Between 2011-2013, 263 CHF patients were included. At inclusion and subsequently every 3 months, we measured N‑terminal pro-B-type natriuretic (NT-proBNP), high-sensitivity troponin T (Hs-TnT) and C‑reactive protein (CRP), and assessed NYHA class...

Post-infarct left ventricle remodelling (LVR) is defined as the structural and functional changes of the myocardium occurring after acute myocardial infarction (AMI) and leading to the loss of contractile tissue and subsequently to post-infarct heart failure (HF). LVR affects 30% of patients after AMI, deteriorating the prognosis. At present, no clinical, biochemical and imaging parameters predict which patients will develop LVR and progress to HF. Despite recent progress in pharmacological treatment, mechanical circulatory support and multidisciplinary team management, none of the available treatments entirely prevent, inhibit or reverse LVR...

BACKGROUND: Several studies have investigated the effects of cardiac resynchronization therapy (CRT) on heart failure (HF), but none have evaluated the pathophysiological pathways involved in a single group of patients. Therefore, this study aims to assess the long-term effects of CRT on six different pathophysiological pathways involved in the process of HF by the use of surrogate biomarkers. METHODS: In a group 44 patients with HF, six groups of biomarkers were measured, both at baseline and 1 year after CRT implantation: Inflammation (interleukin [IL]-4, IL-6, tumor necrosis factor [TNF]-α, high sensitive C-reactive protein [hsCRP]); oxidative stress (myeloperoxidase, oxidized low-density lipoprotein [oxLDL], uric acid); extracellular matrix (ECM) remodeling (matrix metalloproteinase [MMP]-2 and -9, galectin-3, procollagen III N-terminal propeptide [prokol-3NT]); neurohormonal pathways (endothelin-1, chromogranin-A); myocyte injury (troponin T, creatine kinase MB fraction [CK-MB]), myocyte stress (B-type natriuretic peptide [BNP])...

BACKGROUND: Endostatin is a circulating endogenous angiogenesis inhibitor preventing neovascularization. Previous studies demonstrated the prognostic value of Endostatin among patients with heart failure with reduced ejection fraction (HFrEF). However, the role of Endostatin among patients with heart failure with preserved ejection fraction (HFpEF) remains unclear. OBJECTIVE: This study aimed to investigate the association between serum Endostatin levels, natriuretic peptide levels and the severity of left ventricular diastolic dysfunction and the diagnosis of HFpEF...
