Myocardial Structure and Function

چکیده
Background. Studies done in potential donors for heart transplantation and in experimental animals have suggested that brain death can have major histopathological and functional effects on the myocardium. Methods and Results. We developed experimental models of brain death using dogs to study the hemodynamic and catecholamine changes, the extent of myocardial structural damage, and the recovery potential of donor hearts obtained from brain-dead donors. Brain death was caused by increasing the intracranial pressure (ICP) suddenly or gradually by injecting saline in an epidural Foley catheter. In a first series of experiments, dogs given a sudden rise in ICP (n=5) showed a hyperdynamic response and

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. ...
متن کاملThe Effect of Aerobic Training on expression of some indices of myocardial hypertrophy and atrophy in rats
Background: Protein synthesis and degradation are dynamically regulated processes that to control the accretion or loss of muscle mass. However, the mechanisms responsible exercise-induced heart hypertrophy remains elusive. The aim of this study was to investigate the effect of aerobic training on expression of some indices of myocardial hypertrophy and atrophy in male rats. Materials and Meth...

Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studie...

Background and Aim: Diabetes is a metabolic disease that is associated with heart injury. It has been shown that exercise training and resveratrol can improve the cardiac structure and function of diabetic subjects. The aim of the present study was to examine the effect of aerobic training along with resveratrol on gene expression of AMPK and MAFbx on cardiac tissue of diabetic experimental mod...
