AIM To evaluate the cardioprotective effect of sevoflurane on a beating heart in patients undergoing coronary artery bypass grafting with normal preoperative left ventricular function. METHODS The randomized controlled study included 32 patients induced with sevoflurane and then randomized to receive either 1 minimal alveolar concentration (MAC) end-tidal(More)
There is controversy about the influence of QT dispersion on the incidence of early ventricular arrhythmias in patients with acute myocardial infarction (AMI). The QT and QTc dispersion (QTd, QTcd) between two groups of patients with AMI were compared: 39 patients with early sustained ventricular tachycardia or ventricular fibrillation (VT/VF) and 40(More)
We tested the hypothesis that levosimendan produced beneficial hemodynamic effects during and after off-pump coronary artery bypass grafting in patients with good preoperative left ventricular function. Levosimendan at low dose (12 microg/kg), high dose (24 microg/kg), or placebo were administered in thirty-one patients in a randomized and four-times masked(More)
INTRODUCTION The incidence of Acute Kidney Injury is nowadays high in critically ill patients. Its etiology is multifactorial and a primary role is played by low cardiac output syndrome. Everything targeted to normalize cardiac output should increase the renal perfusion and abolish the secondary vasoconstriction. Levosimendan is a calcium sensitizer drug(More)
OBJECTIVE Patients undergoing cardiac surgery are at risk of perioperative low cardiac output syndrome due to postoperative myocardial dysfunction. Myocardial dysfunction in patients undergoing cardiac surgery is a potential indication for the use of levosimendan, a calcium sensitizer with 3 beneficial cardiovascular effects (inotropic, vasodilatory, and(More)
AIM To determine if levosimendan could improve cardiac performance during off-pump coronary artery bypass grafting in patients with normal preoperative left ventricular function. METHODS Twenty-four patients included in this double-blind randomized controlled trial received either placebo (n=12) or 12 microg/kg loading dose of levosimendan (n=12) during a(More)
The aim of the study was to compare the effect of sevoflurane and propofol anesthesia on myocardial contractility during laparotomic cholecystectomy using transesophageal echo-Doppler. In the study, 40 patients were randomized into two groups, depending on whether they received sevoflurane or propofol anesthesia. Heart rate, cardiac index, stroke volume,(More)
OBJECTIVE There is initial evidence that the use of volatile anesthetics can reduce the postoperative release of cardiac troponin I, the need for inotropic support, and the number of patients requiring prolonged hospitalization following coronary artery bypass graft (CABG) surgery. Nevertheless, small randomized controlled trials have failed to demonstrate(More)
