AIMS This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other(More)
UNLABELLED The aim of this study was to investigate the effectiveness of ST 567 in patients suffering from ischaemic heart disease and to compare the effects of this drug with those of propranolol. The study group consisted of 48 male patients, mean age 53, with stable, exercise-induced angina pectoris. After a two-week run-in-placebo period, the patients(More)
Xanthine oxidoreductase has been demonstrated in the heart of various species. However, its presence in human heart is still debated. In the literature, high to undetectable levels have been reported. We studied the arterial-venous urate difference across the heart of patients undergoing both routine cardiac catheterization and percutaneous transluminal(More)
The energetic role of inosine (INO) remains controversial. The aim of the present study was first to test whether endogenous INO consumption/production correlates with regional myocardial contractile performance and second to test whether locally increased levels of INO influence contractility and blood flow in severely ischemic myocardium.(More)
In acute experiments on open chest pigs 15 min occlusions of the left anterior descending coronary artery were performed, each occlusion followed by 45 min reperfusion. Myocardial ischaemia was defined by epicardial electrogram recorded from the border of the ischaemic area. Myocardial extraction of lactate and glucose as well as the extraction of FFA were(More)
Although inosine has been used clinically to support the myocardium, no data are available on the fate of exogenous inosine in the human heart. We therefore infused six patients, catheterised for coronary angiography, with inosine (5 mg.kg-1.min-1 intravenously) for 6 minutes. Before infusion, the arterio-venous difference of inosine, hypoxanthine and(More)
Increased activity of sympathetic nervous system enhances cardiac susceptibility to arrhythmias. Clonidine through its central action decrease sympathetic activity to the heart. The aim of this study was to investigate whether Clonidine influences excitability and refractoriness of the heart in such a way that cardiac susceptibility to arrhythmias is(More)
The metabolic and haemodynamic effects of adrenaline were investigated in 6 intact anaesthetized dogs, which were subjected to an infusion of adrenaline. The dose given was similar to the endogenous production rate of adrenaline in experimental myocardial infarction. Adrenaline infusion (0.8, 1.17 or 1.05μg · kg−1. min−1) over two hours led to a variable(More)
Partial anomalous pulmonary venous connection (PAPVC) is an extremely rare congenital condition where one or more of the pulmonary veins are connected to the venous circulation. Although initially suspected with unexplained right ventricular enlargement on transthoracic echocardiography (TTE), cardiac MRI is able to delineate the anatomical variant. We(More)
