diagnosis of cardiac tamponade has been mainly based on clinical features and echocardiography. however, ct may be an initial tool for the evaluation of cardiac tamponade because cutting edge ct is increasingly being installed in the emergency room, and presentation of cardiac tamponade can be nonspecific. importantly, ct has better spatial resolution compared with echocardiography. thus, ident...
Background and purpose: Cardiac magnetic resonance imaging (MRI) is a costly method to assess cardiac iron overload. The presence of fragmented QRS (fQRS) indicates changes due to iron overload in cardiac tissue. The aim of this study was to evaluate the correlation between fQRS and cardiac iron overload using cardiac MRI in patients with β-thalassemia major (β-TM). Materials and methods: This...
Introduction: Recent reports have shown that rare fluctuations in cardiac cycles are ‘forgotten’ quickly in healthy individuals and it is possible to quantify the “memory length” of a physiological time-series using an inverse statistical approach. Methods: In the present study, we assessed the effect of aging on memory length in cardiac rhythm. Results: There was a long...
trauma is the leading cause of death in united states in the younger population. cardiac trauma is common following blunt chest injuries and is associated with high morbidity and mortality. this study discusses various multidetector computed tomography (mdct) findings of cardiac trauma. cardiac injuries are broadly categorized into the most commonly occurring blunt cardiac injury and the less c...
The importance of cardiac biomarkers in the prognosis of patients with acute coronary syndrome is clear. However, there are some controversies regarding measuring these cardiac biomarkers post angioplasty through percutaneous coronary intervention (PCI). In this study we will review the importance of increased cardiac biomarkers after elective PCI on the prognosis of patients. Also, the definit...
Heart contains a variety of neurons known to influence cardiac functions. Little is known about the neurochemistry of these neurons. In this study, neurochemistry of intra cardiac neurons of the intrinsic cardiac ganglia was investigated. The technique used allows studying the morphology of the ganglionated nerve plexus found within the atria and great cardiac vessels as well as of individual n...
In this investigation, 25 adult New Zealand White rabbits randomly selected from both sexes and studied.Coloured latex injection and corrosion cast methods were applied on the materials. This study was carried out to disclose the distribution of the cardiac veins of the New Zealand White rabbits. The veins that drain the heart were found to be the great cardiac vein, the middle cardiac vein, th...

Cardiac symptoms and premature death from cardiac causes are still major problem with beta thalassemia despite chelation therapy. Heart complications are the leading causes of mortality in the absence of effective iron chelation therapy. Many patients develop evidence of iron-induced myocardial damage with cardiac failure, cardiac arrhythmia, sudden death or death from progressive conge...
Introduction: Coping ways with stress in coronary heart disease patients can lead to significant changes in levels of Cardiac Biomarker Troponin I, but researchers had not explored it empirically. So, the main objective of this study was to identify the relationship between coping ways with stress and Cardiac Biomarker Troponin I and also, finding coping ways that predict changes in the concent...
