1. Adrenomedullin is a recently discovered vasodilating and natriuretic peptide whose physiological and pathophysiological roles remain to be established. Like atrial natiuretic peptide adrenomedullin is expressed in the left ventricle. Ventricular expression of atrial natriuretic peptide is known to be markedly increased by volume or pressure overload. In(More)
The aim of this study was to investigate the time course of deterioration of functional capacity in the rat after ligation of the left coronary artery. Functional capacity was evaluated from the increase in blood lactate concentrations in 109 rats during a standardised treadmill test. Animals with myocardial infarction were compared with sham operated and(More)
Chronic heart failure (HF) is associated with hemodynamic changes and activation of several neurohormonal systems, which are able both to inhibit and to facilitate arterial growth or remodeling and also to influence endothelial function. As these vascular changes may depend on the duration of HF, we evaluated morphologic and endothelial functional(More)
OBJECTIVE Our purpose was to study local angiotensin-converting enzyme activity and the mechanical effects of angiotensin I and II in human uteroplacental arteries. STUDY DESIGN Angiotensin-converting enzyme activity was measured by a simple radioimmunoassay with tritiated benzoyl-glycyl-glycyl-glycine as substrate in isolated human intramyometrial(More)
Eight patients with mild heart failure were treated in random order for 1 week with 2 mg bumethanide at 0800 and 1200 (treatment 1) h, 1 mg bumethanide at 0800, 1200, 1800, 2200 (treatment 2) and 5 mg bendroflumethiazide at 0800 and 1800 (treatment 3) h. The 'quality of life' did not differ significantly between the three treatment periods. At the presumed(More)
Previous studies have demonstrated numerous immunobiological changes in connection with exercise. A decrease in peripheral blood mononuclear white cells (PBMC) 2 h after intense exercise has been shown. This lymphocytopenia in humans after exercise is thought to be of great importance regarding the morbidity to viral infection. We constructed an animal(More)
1. It has been suggested that local tissue renin-angiotensin systems may be activated in heart failure and that effects on such systems may, at least partially, explain the beneficial effects of angiotensin-converting enzyme (ACE) inhibitors in this syndrome. To investigate these hypotheses, we examined expression of renin-angiotensin system components in(More)
