OBJECTIVES Electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. The leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. The aim of this study is to research the effect of ATP-dependent potassium (KATP) channel blocker (glibe...

BACKGROUND Myocardial perfusion single photon emission computed tomography (MPS) is frequently used as the reference method for the determination of myocardial infarct size. PERFIT(R) is a software utilizing a three-dimensional gender specific, averaged heart model for the automatic evaluation of myocardial perfusion. The purpose of this study was to compare the perfusion defect size on MPS, as...

This study intended to assess the efficacy of acute administration of natural honey on cardiac arrhythmias and infarct size when it is used during the normothermic ischemia in isolated rat heart. During 30 min of regional normothermic ischemia followed by 120 min of reperfusion, the isolated hearts were perfused by a modified drug free Krebs-Henseleit solution (control) or the solution containi...

AIMS Global angiographic scores have been developed to determine the extent of myocardium jeopardized by significant coronary stenosis. We adapted these scores to quantify the anatomic area at risk during acute myocardial infarction. We used contrast-enhanced magnetic resonance (CMR) infarct imaging to measure the portion of myocardium that developed necrosis within the so defined angiographic ...

Background: Decompressive craniectomy is an effective treatment for malignant middle cerebral artery (MCA) territory infarct. But the age limit surgery not well defined. The time window of considered less than 96 hours.Methods: This retrospective study 60 patients MCA infarct who underwent decompressive selected in this and using modified Rankin score.Results: In 36 were years above years. 38 r...

introduction: several studies have indicated that late treatment of aminoguanidine (ag) reduces cerebral ischemic injuries in animal models. however, the effects of early treatment of ag on cerebral ischemic damage are not well understood. this study was designed to evaluate effect of early treatment of ag on cortex and striatum injuries as well as neurological dysfunctions in transient model o...
