BACKGROUND: Congestion in heart failure (HF) induces multiple organ injury, which may cause remodeling of extracellular matrix. We hypothesized that liver fibrogenesis marker, 7S domain of collagen type IV (P4NP 7S) was correlated with congestion and liver injury in HF. METHODS AND RESULTS: We measured serum P4NP 7S in two cohorts. Cohort 1 included 70 patients undergoing catheterization. P4NP 7S was correlated with pulmonary capillary wedge pressure, right ventricular and atrial pressure (r=0...

BACKGROUND: The precursor peptide of atrial natriuretic peptide (MR-proANP) has a physiological role in fluid homeostasis and is associated with mortality and adverse clinical outcomes in heart failure patients. Little is known about the prognostic potential of this peptide for long-term mortality prediction in community-dwelling patients. We evaluated associations of MR-proANP levels with 10-year all-cause mortality in patients visiting their general practitioner for a respiratory tract infection...

This study was aimed to analyze the potential role of Corin in the procession of diabetic ED and to explore the underlying mechanism. Diabetic ED rat model was constructed and the characteristics of diabetic ED and control rats were recorded at 4, 8, 12 and 16 weeks. qRT-PCR and Western bloting were used to detected the mRNA and protein levels. Intracellular cGMP detection was accomplished using a commercial radioimmunoassay method. Vascular endothelial cell from rat corpus cavernosum spiral artery was isolated and transfected with si- Corin to analyzed the potential role of Corin...

: We assessed the effects of liraglutide treatment on five cardiovascular risk biomarkers, reflecting different pathophysiology: 1) Tumour necrosis factor-alpha (TNF-alpha); 2) Soluble urokinase plasminogen activator receptor (suPAR); 3) Mid-regional pro-adrenomedullin (MR-proADM); 4) Mid-regional pro-atrial natriuretic peptide (MR-proANP); and 5) Copeptin, in type 2 diabetes patients with albuminuria. In a randomised, double-blind, placebo-controlled, cross-over trial we enrolled patients with type 2 diabetes and persistent albuminuria (urinary albumin-to-creatinine ratio (UACR) > 30 mg/g) and estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1...

We have previously reported that a long-acting loop diuretic, azosemide, reduces cardiovascular risks in patients with chronic heart failure (CHF) as compared with a short-acting one, furosemide, in Japanese Multicenter Evaluation of LOng- versus short-acting Diuretics In Congestive heart failure (J-MELODIC). However, the mechanisms of the difference have not been elucidated. This study aimed to examine whether there is a difference in the reduction in plasma brain natriuretic peptide (BNP) level and in left ventricular (LV) functional recovery between the CHF patients treated with the long-acting diuretic (the azosemide group) and the short-acting diuretic (the furosemide group)...

Although recent studies show an improved survival of children with sickle cell disease in the US and Europe, mortality remains high for adult patients. This study was conducted to evaluate the factors associated with mortality in adult patients following the approval of hydroxyurea. We first evaluated the association between selected variables and mortality at an academic center (UNC cohort). Data sources were then searched for publications from 1998 to June, 2016, with meta-analysis of eligible studies conducted in North America and Europe to evaluate the associations of selected variables with mortality in adult patients...

BACKGROUND: The change in the level of NT-Pro-BNP (N-terminal Pro-Brain Natriuretic Peptide) is now considered as a reflection of the hemodynamic alterations and its circulatory reductions reported early after successful PTMC (percutaneous transvenous mitral commissurotomy). The present study aims to assess the change in the level of NT-Pro BNP following PTMC in patients with mitral stenosis and also to determine the association between circulatory NT-Pro BNP reduction and post-PTMC echocardiography parameters...

BACKGROUND: Heart failure is a condition in which the heart does not pump enough blood to meet all the needs of the body. Symptoms of heart failure include breathlessness, fatigue and fluid retention. Outcomes for patients with heart failure are highly variable; however on average, these patients have a poor prognosis. Prognosis can be improved with early diagnosis and appropriate use of medical treatment, use of devices and transplantation. Patients with heart failure are high users of healthcare resources, not only due to drug and device treatments, but due to high costs of hospitalisation care...

BACKGROUND: Elderly patients with hip fracture are at risk for cardiac complications. N-terminal pro-brain type natriuretic peptide (NT-proBNP) has been shown to predict cardiac complications in surgical patients; however, to our knowledge, only two studies have evaluated the utility of this test in patients with hip fracture. We believe it is important to assess a more accurate cutoff value of NT-proBNP with exclusion of patients with renal failure. QUESTIONS/PURPOSES: To assess the association between preoperative NT-proBNP and cardiac complications after hip fracture surgery...

PURPOSE: Cisplatin is an effective chemotherapeutic agent used to treat a variety of malignant tumors. The major toxicity associated with cisplatin treatment is granulocytopenia. C-type natriuretic peptide (CNP), a member of the natriuretic peptide family, protects against toxicity in many organs, including the heart, blood vessels, lung, and kidney. The objective of this study was to investigate the myeloprotective effects of CNP in a mouse model of cisplatin-induced granulocytopenia...

A label-free immunosensor platform based on excessively tilted fiber gratings (Ex-TFGs) was developed for highly specific and fast detection of human N-terminal pro-B-type natriuretic peptide (NT-proBNP), which is considered a powerful biomarker for prognosis and risk stratification of heart failure (HF). High-purity anti-NT-proBNP monoclonal antibodies (MAbs) prepared in our laboratory were immobilized on fiber surface through the staphylococcal protein A (SPA) method for subsequent specific binding of the targeted NT-proBNP...

The action mechanism of natakalim, a novel ATP-sensitive potassium channel opener, was studied in ameliorating the congestive heart failure (CHF) after myocardial infarction. A total of 25 healthy Wistar male rats (age, 10 weeks; average weight, 300 g) were selected, and the CHF models after acute myocardial infarction (AMI) were prepared by ligation of left anterior descending branch. They were randomly divided into the sham operation group, the model group and the groups of 1, 3 and 9 mg/kg/day natakalims...

OBJECTIVE: Xindening oral liquid (Xin) is a widely used traditional Chinese medicine for the treatment of chronic heart failure (CHF). However, the exact mechanisms related to its therapeutic effects against CHF remain unclear. In the present study, we investigate the effects of Xin on cardiac function in CHF rats and the possible mechanisms involved. METHODS: Transverse aortic constriction (TAC) was conducted to induce a CHF rat model in this study. Sixty male Wistar rats were randomly assigned to six groups 28 days after TAC: sham; CHF model; Xin at concentrations of 5 ml/kg, 10 mL/kg, and 20 mL/kg; and QiLi 0...

The mechanism of cardiac hypertrophy involving microRNAs (miRNAs) is attracting increasing attention. Our study aimed to investigate the role of miR-10a in cardiac hypertrophy development and the underlying regulatory mechanism.Transverse abdominal aortic constriction (TAAC) surgery was performed to establish a cardiac hypertrophy rat model, and angiotensin II (AngII) was used to induce cardiac hypertrophy in cultured neonatal rat cardiomyocytes. Expression of T-box 5 (TBX5) and miR-10a was altered by cell transfection of siRNA or miRNA mimic/inhibitor...

BACKGROUND: In hemodialysis patients, fluid overload and malnutrition are accompanied by extracellular fluid (ECF) expansion and intracellular fluid (ICF) depletion, respectively. We investigated the relationship between ECF/ICF ratio (as an integrated marker reflecting both fluid overload and malnutrition) and survival and cardiovascular disease (CVD) in the context of malnutrition-inflammation-arteriosclerosis (MIA) complex. METHODS: Seventy-seven patients from a single hemodialysis unit were prospectively enrolled...

BACKGROUND: Presepsin (soluble cluster-of-differentiation 14 subtype [sCD14-ST]) is a humoral risk stratification marker for systemic inflammatory response syndrome and sepsis. It remains unknown whether presepsin can be used to stratify risk in elective cardiac surgery. The authors therefore determined the usefulness of presepsin for risk stratification in patients having elective cardiac surgery.
