Left ventricular unloading before reperfusion reduces endothelin-1 release and calcium overload in porcine myocardial infarction.
OBJECTIVES The aim of this study was to test the hypothesis that after an acute myocardial infarction, endothelin-1 release with subsequent calcium overload is a mediator of myocardial reperfusion injury, which can be inhibited, in part, by left ventricular unloading immediately before reperfusion. We recently have reported that left ventricular unloading before reperfusion reduces infarct size...
متن کاملLeft ventricular unloading during reperfusion.
1543 it before publication.' We have recently become aware of a published thesis by Margot M. Bartelings8 at the University of Leiden that discusses cardiac development and uses the new terminology of Pexieder et a17 as well as the classic nomenclature. Although we are in general satisfied with this suggested nomenclature,7 we believe it would benefit from clarification on two points. For our o...
متن کاملThe influence of acute unloading on left ventricular strain and strain rate by speckle tracking echocardiography in a porcine model.
Noninvasive measurements of myocardial strain and strain rate by speckle tracking echocardiography correlate to cardiac contractile state but also to load, which may weaken their value as indices of inotropy. In a porcine model, we investigated the influence of acute dynamic preload reductions on left ventricular strain and strain rate and their relation to the pressure-conductance catheter-der...
متن کاملMyocardial recovery by mechanical unloading with left ventricular assist system.
It has been generally believed that advanced congestive heart failure (HF) is progressive, but there is increasing evidence that mechanical unloading with the use of left ventricular assist system (LVAS) occasionally reverses the progress of HF and permits device explantation. This "bridge to recovery" strategy is attracting interest, not only for the treatment of severe HF, but also in the stu...
متن کاملVentricular unloading, tissue angiotensin II, matrix modulation, and function during left ventricular assist device support.
eart failure (HF) has become the major epidemic of the ew millennium, and use of the left ventricular (LV) assist evice (LVAD) for mechanical support in end-stage HF is ncreasing. Introduced as an alternative to heart transplanation, LVADs were approved by the Food and Drug dministration a decade ago to provide a bridge to translantation in the moribund end-stage HF patient waiting or a donor h...
