Background—Insulin has been shown to exert positive inotropic effects in several in vitro and in vivo models, but signal transduction and substrate dependency remain unclear. We examined inotropic responses and signal transduction mechanisms of insulin in human myocardium. Methods and Results—Experiments were performed in isolated trabeculae from end-stage failing hearts of 58 nondiabetic and 3...
Many adult patients require temporary inotropic support after cardiac surgery. We reviewed the literature systematically to establish, present and classify the evidence regarding choice of inotropic drugs. The available evidence, while limited in quality and scope, supports the following observations; although all beta-agonists can increase cardiac output, the best studied beta-agonist and the ...
Brixius, Klara, Marcus Pietsch, Susanne Hoischen, Jochen Müller-Ehmsen, and Robert H. G. Schwinger. Effect of inotropic interventions on contraction and on Ca21 transients in the human heart. J. Appl. Physiol. 83(2): 652–660, 1997.—The present study investigated the influences of inotropic intervention on the intracellular Ca21 transient 5intracellular Ca21 concentration ([Ca]i)6 and contractil...
Angiotensin II (Ang II) has been recognized as an important myocardial inotropic modulator, but the subtleties of the signalling pathways involved remain to be fully elucidated. The inotropic effect of Ang II reflects the net outcome of competing positive and negative signalling mechanisms. In pathophysiological states such as heart failure, characterized by chronic exposure to elevated Ang II,...
