AIMS Insulin promotes Akt-dependent prosurvival signaling and reduces experimental ischemia reperfusion injury, but its clinical impact has been limited. Further understanding of the interplay between insulin and Akt in the myocardium of relevant large animal models is needed. We aimed to investigate (1) Akt phosphorylation, (2) influence of feeding state,(More)
INTRODUCTION Naturally occurring antibodies are linked to inflammation, tissue injury and apoptosis, processes also linked to heart failure. Associations between antibodies, inflammation and myocardial damage, have not been elucidated in heart failure. OBJECTIVE We investigated if 25 antibodies to receptors expressed in the cardiovascular system were(More)
AIM Insulin and glucose may have opposite effects when used to reduce ischemia-reperfusion injury. When insulin is administered alone, feeding state determines tolerance and further induces metabolic and hormonal changes. Higher insulin doses are needed for similar activation of cardioprotective Akt signaling in the fed compared to the fasted pig heart.(More)
Maintaining adequate organ perfusion during cardiac arrest remains a challenge, and various assist techniques have been evaluated. We assessed whether a right ventricular impeller assist device (RVAD) in adjunct to a left ventricular impeller assist device (LVAD) is beneficial. Twenty anesthetized pigs were randomized to maximized circulatory support by(More)
Insulin given at immediate reperfusion reduces myocardial infarct size in the in vitro and the ex vivo rat heart. In vivo, insulin may cause hypoglycaemia, hypokalaemia and elevation of catecholamines, potentially harmful during an acute myocardial infarction. The purpose of this study was to evaluate tolerance and safety of intracoronary insulin infusions(More)
BACKGROUND To better understand how prolonged electrical muscle stimulation can improve cardiorespiratory risk markers in obese subjects, we investigated the effect of prolonged combined thermal and electrical muscle stimulation (cTEMS) on peak oxygen consumption (VO2peak) and body composition with subsequent lipolytic and mitochondrial activity in(More)
