Atrial (ANP), brain (BNP), and C-type natriuretic peptide (CNP) belong to a family of hormones important in blood pressure and sodium homeostasis. Expression of ANP has been reported in embryo hearts, but BNP and CNP expression during development has not been described. We used in situ hybridization to identify the sites of gene expression of ANP, BNP, and(More)
BACKGROUND There is currently no objective practical guide to intensity of drug treatment for individuals with heart failure. We hypothesised that pharmacotherapy guided by plasma concentrations of the cardiac peptide aminoterminal brain natriuretic peptide (N-BNP) would produce a superior outcome to empirical trial-based therapy dictated by clinical(More)
BACKGROUND A recent landmark report has demonstrated that plasma B-type natriuretic peptide (BNP) measured in acute coronary syndromes independently predicts mortality, heart failure, and new myocardial infarction. After acute cardiac injury, left ventricular ejection fraction (LVEF) is also of prognostic significance and plays a major role in determining(More)
AIM To determine the renal, endocrine and haemodynamic effects of an orally active inhibitor of the neutral endopeptidase EC in essential hypertension. METHODS Two groups of 12 white male patients with essential hypertension were treated with candoxatril at 25 mg every 12 h (group 1) or at 200 mg every 12 h (group 2) for 5 days in double-blind,(More)
The effects of an orally active inhibitor (UK 79300) of the neutral metalloendopeptidase EC were investigated in six healthy male volunteers maintained on a constant diet (150 mmol sodium/day and 80 mmol potassium/day). Subjects were studied in a random order, single-blind study on two occasions, each 48 hours in length, when they were given UK(More)
In order to examine the effect of growth hormone (GH) on psychological parameters in adult hypopituitarism, 20 adults were studied, mean age 47 years (range 20-69) with hypopituitarism and confirmed GH deficiency (GH < 3 micrograms/l following clonidine 0.15 mg/m2). Subjects were randomly allocated to either GH-up to 0.25 U/kg per week in daily doses) or(More)
Although it is assumed that the human heart secretes atrial peptides, direct proof is not available. We therefore measured immunoreactive atrial natriuretic peptide levels in coronary sinus blood and simultaneously in femoral arterial and venous blood from patients before and during stepwise incremental atrial pacing of up to 200 beats per minute. Since the(More)
Radio-immunoassay of atrial natriuretic peptide (ANP) and infusions of alpha-human ANP (alpha-hANP) have been used to study the secretion, metabolism, regulation and actions of ANP in man. Plasma immunoreactive ANP (irANP) was twice as high in arterial blood as in simultaneously sampled venous plasma from the femoral, hepatic and renal vein, but no(More)
In order to determine arterial pressure and vasoactive hormone relationships in normotensive man, we measured intra-arterial pressure continuously along with hourly venous hormone levels (renin, angiotensin II, aldosterone and catecholamines) for 24 hours in 5 healthy volunteers under standardized conditions. Mean 24-hour levels of intra-arterial pressure(More)
