AIM The aim of this study was to evaluate the diagnostic utility of natriuretic peptides of type A and B as noninvasive markers in the diagnosis and treatment of congenital and valvular heart disease. METHODS Blood samples from 82 patients with various congenital and valvular heart diseases were measured for A and B natriuretic peptide levels and levels compared with those in a reference grou...
Since the initial studies showing the usefulness of B-type natriuretic peptide for aiding in heart failure diagnosis, a vast number of other clinical applications for this neurohormone have emerged. In addition to refining our capabilities to diagnose and prognosticate in acute heart failure, natriuretic peptides are now being used in outpatient heart failure clinics, in screening programs, and...
Cultured rat vascular smooth muscle cells (VSMCs) possess receptors for potent vasoconstrictor endothelin-1 (ET-1) as well as potent vasodilator natriuretic peptides (atrial, brain, and C-type natriuretic peptides [ANP, BNP, and CNP, respectively]). However, little is known about molecular interactions between endothelin receptors and natriuretic peptides in VSMCs. To elucidate whether natriure...
BACKGROUND Diabetes mellitus and heart failure frequently coexist. However, few diabetes mellitus trials have prospectively evaluated and adjudicated heart failure as an end point. METHODS AND RESULTS A total of 16 492 patients with type 2 diabetes mellitus and a history of, or at risk of, cardiovascular events were randomized to saxagliptin or placebo (mean follow-up, 2.1 years). The primary...
Background Atrial (ANP), B-type (BNP) and C-type (CNP) natriuretic peptide levels are increased in heart failure. Natriuretic peptides mediate their effects through natriuretic peptide receptors (NPRs), ANP and BNP preferentially through NPR-A and CNP through NPR-B. NPRs are membrane bound guanylyl cyclases that increase cyclic GMP (cGMP) production when activated. Increased cGMP levels may hav...
BACKGROUND Aortic valve calcification is an actively regulated process that displays hallmarks of atherosclerosis. Natriuretic peptides (A-, B-, and C-type natriuretic peptides [ANP, BNP, and CNP]) have been reported to have a role in the pathogenesis of vascular atherosclerosis, but their expression in aortic valves is not known. Here, we characterized and compared expression of natriuretic pe...
C ardiac ventricles release B-type natriuretic peptide (BNP) in response to volume expansion and pressure overload; therefore, BNP concentration may be used as a biochemical marker of cardiac failure (1). BNP levels are high in diabetic subjects with left ventricular dysfunction (2). Because the diagnosis of cardiac failure may be an emergency (3), it is important to know whether the timing of ...
Since its introduction to the intensive care setting a decade ago, B-type natriuretic peptide has been the focus of studies in different areas (in particular, sepsis). With this biomarker, as with many newly identified biomarkers, its diagnostic performance was pursued initially and then its ability to predict outcomes. Despite all the efforts, results have not been consistent and the applicati...
We isolated the human C-type natriuretic peptide gene and identified the peptide in the brain. The human C-type natriuretic peptide gene appeared to be composed of at least two exons and one intron. In the 5'-flanking region, there is an array of cis elements (an inverted CCAAT box, two GC boxes, and a cyclic AMP response element-like sequence) that is not present in upstream sequences of the a...
