BACKGROUND Telemonitoring of patients with chronic heart failure (CHF) is an emerging concept to detect early warning signs of impending acute decompensation in order to prevent hospitalization. OBJECTIVE The goal of the MOBIle TELemonitoring in Heart Failure Patients Study (MOBITEL) was to evaluate the impact of home-based telemonitoring using Internet(More)
The so-called hypothenar hammer syndrome is a rare entity caused by lesions of the ulnar artery secondary to repetitive trauma to the hypothenar eminence, typically found in persons working with vibrating tools. Its clinical symptoms are pain, stiffness and whitening of the smitten fingers, sometimes in combination with Raynaud's syndrome. Angiographic(More)
PURPOSE To report the initial experience with a new catheter system (The Outback catheter) designed to allow fluoroscopically controlled re-entry of the true arterial lumen after subintimal guidewire passage during recanalization procedures of arterial occlusions. METHODS The catheter was used in 10 patients with intermittent claudication caused by(More)
Percutaneous removal of renal and ureteral calculi has become an established and successful procedure in adults. Stone disease in children often is metabolic or infectious in origin and multiple surgical procedures during a long interval may be required. Therefore, percutaneous stone removal could be particularly advantageous in these patients. We have(More)
One-hundred and fifty patients with thrombotic and 60 patients with embolic occlusions of the superficial femoral and/or popliteal artery underwent a simplified IAT (intra-arterial thrombolysis) procedure. Ten mg rt-PA combined with 3000 IU Heparin were infused over 6 h, thereafter the extent of thrombolysis was checked fluoroscopically and the above(More)
BACKGROUND The vasoactive effect of nicorandil on coronary arteries is well known. Nicorandil exerts its vasodilatory effect through a dual mechanism of action: involving on the one hand cyclic guanosine monophosphate (c GMP) as a nitrovasodilatator, and on the other hand, acting as a potassium channel opener. OBJECTIVE To address the question if(More)
Diabetes mellitus is thought to increase the susceptibility of tissue to hypoxic injury through D-glucose-induced alterations of intracellular metabolism. Therefore the effects of hyperglycaemia on coronary artery autoregulation under slight reduction of coronary flow were investigated in isolated perfused guinea-pig hearts. Under normal (10 mM) D-glucose(More)
PURPOSE The antiarrhythmic efficacy of adenosine during states of AV-nodal reentrant tachycardias is well known and clinically established. Adenosine is also able to reduce ventricular arrhythmias when applied before coronary ligation in rats. Hypoxia or ischemia leads to an increased production of adenosine by cardiac myocytes. The purpose of this study(More)
We developed a new protocol for diagnosis and treatment of patients with sustained tachycardias (heart rate > 150 beats.min-1). The patients first underwent vagal manoeuvres; if those remained unsuccessful, i.v. adenosine in increasing doses of 6, 12, and 18 mg was administered until sinus rhythm (SR) or transient atrioventricular (AV) block, unmasking the(More)
Angiotensin-converting enzyme (ACE) inhibitors are of benefit in life-threatening ventricular arrhythmias in patients with congestive heart failure and ventricular tachycardia caused by the onset of myocardial ischemia as well as by reperfusion of an ischemic area. The aim of the present study was to investigate whether direct electrophysiological effects(More)
