OBJECTIVES We sought to define the therapeutic dose range of levosimendan in patients with New York Heart Association class II-IV heart failure of ischemic origin. BACKGROUND Levosimendan is a calcium sensitizer for treatment of acute decompensated heart failure. METHODS A double-blind, placebo-controlled, randomized, multicenter, parallel-group study(More)
Aims To evaluate the safety and efficacy of levosimendan in patients with left ventricular failure complicating acute myocardial infarction. Methods and Results Levosimendan at different doses (0·1–0·4 g. kg 1. min 1) or placebo were administered intravenously for 6 h to 504 patients in a randomised, placebo-controlled, double-blind study. The primary(More)
OBJECTIVES We assessed the effects of levosimendan on left ventricular (LV) function in patients with acute myocardial ischemia and after coronary angioplasty. BACKGROUND The calcium sensitizer levosimendan improves the function of myocardium in experimental stunning. METHODS Twenty-four patients with an acute coronary syndrome underwent angioplasty(More)
AIMS To evaluate the safety and efficacy of levosimendan in patients with left ventricular failure complicating acute myocardial infarction. METHODS AND RESULTS Levosimendan at different doses (0.1-0.4 microg x kg(-1) x min(-1)) or placebo were administered intravenously for 6h to 504 patients in a randomised, placebo-controlled, double-blind study. The(More)
OBJECTIVE Levosimendan is a new calcium sensitizer with additional vasodilatory properties developed for the short-term intravenous treatment of congestive heart failure. The aims of the present study were to determine the pharmacokinetics and hemodynamic effects of levosimendan and its metabolites during and after a 24-hour levosimendan infusion. METHODS(More)
Levosimendan is a new calcium sensitizer developed for the short-term intravenous treatment of congestive heart failure. The aims of the present open-label, nonrandomized study were to determine the tolerability, hemodynamic effects, and the basic pharmacokinetics of levosimendan and its metabolites during an extended continuous infusion of levosimendan.(More)
—This paper analyses the effects of Network-on-Chip (NoC) models written in SystemC on simulation speed. Two Register Transfer Level (RTL) models and Approximately Timed (AT) and Loosely Timed (LT) Transaction Level (TL) models are compared against reference RTL VHDL 2D mesh model. Three different mesh sizes are evaluated using a commercial simulator and(More)
AIMS Levosimendan, a novel calcium-dependent calcium sensitizer of the myocardial contractile proteins, also enhances diastolic relaxation and induces peripheral vasodilation by opening potassium channels. To assess the combined energetical effects of levosimendan infusion in vivo, we performed positron emission tomography in patients with decompensated(More)
Provocation of fatal cardiac arrhythmias has limited the use of inotropic agents as heart failure therapy. Calcium sensitization of the myofilaments might increase inotropy without influencing cardiac electrophysiology unless modified by ancillary properties of the drugs. Electrophysiologic effects of a calcium sensitizer inotrope levosimendan were examined(More)
AIMS The aim of the study was to evaluate the effects on systemic and coronary haemodynamics and myocardial substrate utilization of a new calcium sensitizer, levosimendan, after coronary artery bypass grafting. METHODS AND RESULTS Twenty-three low-risk patients were included in this randomized and double-blind study. They received placebo (n = 8), 8 (n =(More)
