Milrinone and levosimendan administered after reperfusion improve myocardial stunning in swine.

OBJECTIVES We assessed the effect of milrinone application timing after reperfusion against myocardial stunning as compared with levosimendan in swine. Furthermore, we examined the role of p38 mitogen-activated protein kinase (p38 MAPK) in the milrinone-induced cardioprotection. DESIGN All swine were subjected to 12-minutes ischemia followed by 90-minutes reperfusion to generate stunned myoca...

[Effect of levosimendan treatment of myocardial stunning and low-output syndrome after cardiac surgery].

The pathophysiologic mechanisms underlying myocardial stunning, especially following heart surgery, are fascinating and optimal treatment of the condition is of fundamental importance. We therefore read the recent article by Álvarez et al1 with great interest and we must congratulate the authors on their excellent work. Nevertheless, we would like to make the following observations. At least 14...

Levosimendan versus milrinone for pediatric cardiac surgery

BACKGROUND: Our aim is to check effectiveness of intravenous Levosimendan in comparison with intravenous Milrinone in congenital heart surgery with cardiopulmonary bypass. MATERIALS AND METHODS: 50 Paediatric patients between 2 months to 12 years of age divided into two groups. Group L (n=25) received inj. levosimendan 12μg/kg over 10 minutes1 after cross clamp removal and 0.1μg/kg/min started ...

Brief increase in carbohydrate oxidation after reperfusion reverses myocardial stunning in conscious pigs.

BACKGROUND Previous studies have examined only acute effects of enhanced glucose oxidation on postischemic myocardium. The goal of the present study was to examine prolonged functional recovery subsequent to postischemic, intracoronary pyruvate dehydrogenase kinase inhibition with dichloroacetate (DCA) of stunned myocardium in conscious pigs. METHODS AND RESULTS Myocardial stunning was induce...

Oxypurinol limits myocardial stunning but does not reduce infarct size after reperfusion.

To explore the role of oxygen free radicals produced by the xanthine oxidase pathway on infarct size and left ventricular function, the effect of oxypurinol, an active metabolite of allopurinol and a potent noncompetitive inhibitor of xanthine oxidase, was assessed in a 90 min, closed-chest, canine preparation of occlusion-reperfusion. Animals were randomized to receive 25 mg/kg iv oxypurinol (...
