BACKGROUND AND AIMS Cardiac dysfunction may be present in patients with cirrhosis. This study was undertaken to relate plasma concentrations of cardiac peptides reflecting early ventricular dysfunction (pro-brain natriuretic peptide (proBNP) and brain natriuretic peptide (BNP)) to markers of severity of liver disease, cardiac dysfunction, and hyperdynamic(More)
BACKGROUND AND AIMS Arterial hypertension is a common disorder. Hyperkinetic circulation and reduced effective volaemia are central elements in the haemodynamic dysfunction in cirrhosis. The aim of the present study was to investigate whether cirrhotic patients with arterial hypertension are normokinetic and normovolaemic or whether they reveal the same(More)
Arterial function may be altered in patients with cirrhosis. We determined compliance of the arterial tree (C(1)) in relation to systemic and splanchnic hemodynamic derangement and clinical variables. C(1) and the stroke volume-pulse pressure index (SV/PP) were significantly higher (+62% and +40%, respectively; P < 0.001) in cirrhotic patients (n = 49) than(More)
BACKGROUND Existing data on gastric emptying and small-intestinal transit rates in portal-hypertensive patients are scarce and contradictory, and so far, the motor function of the colon has not been assessed in these patients. In this study we evaluated the propulsive effect of all main segments of the gastrointestinal tract in patients with(More)
BACKGROUND/AIMS Previous investigations have shown a prolonged QT interval in some patients with cirrhosis. The aim of this study was to investigate the relation between electrical and mechanical systole in patients with different degrees of severity of cirrhosis. METHODS Forty-eight patients with cirrhosis and portal hypertension, studied during a(More)
BACKGROUND/AIMS The Q-T(c) interval is prolonged in a substantial fraction of patients with cirrhosis, thus indicating delayed repolarisation. However, no information is available in mild portal hypertensive patients. We therefore determined the Q-T(c) interval in cirrhotic patients with hepatic venous pressure gradient (HVPG) < 12 mmHg. METHODS(More)
BACKGROUND Sacral nerve stimulation (SNS) is a well-established treatment for fecal incontinence of various etiologies. However, the mechanism of action remains unclear. The aim of the present study was to determine whether SNS affects gastric emptying, small intestinal transit or colonic transit times. METHODS Seven patients with a permanently implanted(More)
OBJECTIVE Prolonged Q-T interval (QT) has been reported in patients with cirrhosis who also exhibit profound abnormalities in vasoactive peptides and often present with elevated heart rate (HR). The aim of this study was to relate QT to the circulating level of endothelins (ET-1 and ET-3) and calcitonin gene-related peptide (CGRP) in patients with(More)
BACKGROUND Little is known about the role of tachykinins on human gastrointestinal motility and no data exist on the possible effect of an NK1 receptor antagonist. AIM To examine the effect of an antiemetic dose of the selective NK1 receptor antagonist aprepitant on gastrointestinal propulsion in healthy humans. METHODS Twelve healthy volunteers(More)
The geometric centre analysis is often used for evaluating colonic transit data obtained by scintigraphy after oral intake of 111indium-labelled diethylenetriamine penta-acetic acid (111In-DTPA). The purpose of this study was to establish reference values for the geometric centre analysis in adult humans. Forty-eight healthy volunteers (24 women, 24 men)(More)
