Abstract Introduction: Resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. The aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% O2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. Methods: Following 60 and 180 minutes of hyperoxia, rat hearts w...

Background: Congenital heart disease is the most common type of maternal abnormality and is the leading cause of mortality in the first year of life. The aim of this study was to determine the epidemiological and related factors of congenital heart disease (CHD) in children referred to the pediatric heart clinic of Vali-e-Asr Hospital of Birjand, Iran. <e...

We assessed the effects of age related changes in chamber size, wall thickness, and heart rate of left ventricular function in 78 normal children, aged 1 1/2 to 12 1/2 years, using computer analysis of their left ventricular echocardiograms. Left ventricular cavity size and wall thickness increased linearly with age. Left ventricular fractional shortening, percentage of wall thickening, and the...

Objective: To determine whether the process of reverse left ventricular remodelling in response to carvedilol is dependent on baseline heart rate (BHR), heart rhythm, or heart rate reduction (HRR) in response to carvedilol. Design: Retrospective analysis of serial echocardiograms in 257 patients with chronic systolic heart failure at baseline and at 12–18 months after starting carvedilol. Rever...

Although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. We report a case of Hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalize...

background: cirrhotic patients are at a greater risk of different kinds of arrhythmias. despite the well-known arrhythmogenic effects of halothane, developing countries continue to use halothane due to its low cost. this study was designed to investigate the pathophysiology of halothane untoward effects on heart rhythm moreover was aimed to explore the effect of halothane anesthesia on the thre...

We propose a Novel Left Ventricular Assist System (Novel LVAS) as a bridge to cardiac transplantation and to functional heart recovery in advanced heart failure. This report regards the principles that led to its development. It is our hope that the design of a high-peak-output pump of smaller size will lead to improved functional capacity, when compared with currently available left ventricula...

Fourteen long term survivors with orthotopic (recipient heart replaced by donor heart) and nine with heterotopic cardiac transplants (recipient heart retained) had 24 hour ambulatory electrocardiographic monitoring to detect ventricular arrhythmias. Arrhythmia was uncommon in the patients with orthotopic transplants; none of them had more than one extrasystole per hour. In the patients with het...

the present study attempted to compare the structural and functional changes of left heart ventricle in female basketball players of khuzestan superior league (aged between 18 and 29) during regular training and long-term detraining. out of 30 female players, 15 subjects were assigned randomly to regular training group and 15 subjects to long-term detraining group. the structural and functional...
