Purpose: Tenascin-C (TN-C) and amino-terminal fragment of the B-type natriuretic peptide (NT-proBNP) are the important predictors in prognosis of heart failure (HF). The aim of this study was to analyze the relationship of TN-C and NT-proBNP levels with the frequency and severity of ventricular arrhythmia. Materials and Methods: Our study included 107 HF patients with EF < 45%. According to Holter analysis, the patients were divided into two groups as malignant arrhythmia group (n=29) with Lown Class 4a and 4b arrhythmia and benign arrhythmia group(n=78) with Lown Class 0-3b arrhythmia. The groups were compared with respect to levels of TN-C and NT-proBNP. The relationship of TN-C and NT-proBNP levels with frequency of ventricular premature beat (VPB) was also analyzed. Findings: NT-proBNP (5042.1±1626 versus 1417.1±1711.6 pg/ml) and TN-C (1089±348.6 versus 758.5±423.9 ng/ml) levels were significantly higher in the malignant arrhythmia group than that of the benign arrhythmia group (p

The character of natriuretic peptide receptors (NPRs) in the kidney and aortae of the Atlantic hagfish Myxine glutinosa was determined and compared with that of NPRs in hagfish gills. The relationship of hagfish kidney and aortic NPRs with NPRs from higher vertebrates was also examined. Iodinated atrial and C-type natriuretic peptides (NPs) (125I-ANP, 125I-CNP) were used in tissue section autoradiography, competition studies and guanylate cyclase (GC) assays. Rat atrial and porcine C-type NPs (rANP, pCNP) and rat des[Gln18, Ser19, Gly20, Leu21 Gly22]ANP-(4-23)-NH2 (C-ANF, which binds to the mammalian and teleost 'clearance' receptor, NPR-C), were used as competing ligands. 125I-ANP binding sites were observed on both aortae and on the glomeruli, neck segments and archinephric ducts of the kidney. 4.0 nmol l-1 rANP competed for 50% of 125I-ANP glomerular sites. 125I-CNP did not visibly bind to any of the tissues, but 300 nmol l-1 pCNP competed for 50% of 125I-ANP glomerular sites. C-ANF failed to compete for 125I-ANP sites. rANP and pCNP stimulated cyclic GMP production in kidney membrane preparations, but C-ANF did not, demonstrating that the hagfish kidney NPR is GC-linked. This study suggests that a predominant population of ANP-like receptors, similar to the mammalian NPR-A, exists in the myxinoid aortae and kidney tissue. However, no detectable population of a receptor that binds all NPs, such as is present in the hagfish gill, nor an NPR similar to the NPR-C of higher vertebrates was discovered.

AbstractIn order to predict the occurrence of worsening renal function (WRF) and of WRF plus in-hospital death, 101 emergency department (ED) patients with acute decompensated heart failure (ADHF) were evaluated with testing for amino-terminal pro-B-type natriuretic peptide (NT-proBNP), BNP, sST2, and neutrophil gelatinase associated lipocalin (NGAL).In a prospective international study, biomarkers were collected at the time of admission; the occurrence of subsequent in hospital WRF was evaluated.In total 26% of patients developed WRF. Compared to patients without WRF, those with WRF had a longer in-hospital length of stay (LOS) (mean LOS 13.1±13.4 days vs. 4.8±3.7 days, p<0.001) and higher in-hospital mortality [6/26 (23%) vs. 2/75 (2.6%), p<0.001]. Among the biomarkers assessed, baseline NT-proBNP (4846 vs. 3024 pg/mL; p=0.04), BNP (609 vs. 435 pg/mL; p=0.05) and NGAL (234 vs. 174 pg/mL; p=0.05) were each higher in those who developed WRF. In logistic regression, the combination of elevated natriuretic peptide and NGAL were additively predictive for WRF (OR: In ED patients with ADHF, the combination of NT-proBNP or BNP plus NGAL at presentation may be useful to predict impending WRF (Clinicaltrials.gov NCT#0150153).
