Myocardial hibernation in the ischemic neonatal heart.

We explored the effects of sustained low-flow ischemia on function and metabolism in isolated neonatal hearts. The hearts were extracted from 21 piglets (1-12 days old) and set up as modified Langendorff preparations beating isometrically. They were perfused with red blood cell-enhanced buffer at controlled rates of coronary flow. Mechanical measurements, O2 usage, and substrate oxidation were ...

Comparison between the effects of L-Carnitine and Acetyl-L-Carnitine on myocardial infarction size in ischemic heart

Introduction: In the present study, potential differences between the effects of L-carnitine (LC) and acetyl-Lcarnitine (ALC) on ischemia/reperfusion (I/R)-induced myocardial infarction size were investigated. Methods: Male Wistar rats were randomly divided into five groups and then anesthetized by sodium pentobarbital. Hearts of the animals were removed and quickly mounted on a Langendorff ...

Evaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy

Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
