Cardiac diseases are common post-stroke and are associated with increased morbidity and mortality. One possible mechanism of acute cardiac injury is the neurogenic myocardial damage, where the cerebral injury is disturbing the normal sympathetic and parasympathetic neuronal outflow to the heart leading to cardiac damage including myocardial infarctions. The exact mechanism is not completely und...

Introduction: Regarding the association between climate, seasons and myocardial infarction, a cross-sectional study was carried out in Shiraz and Bandar Abbas in Iran. Methods: All patients with diagnosis of acute myocardial infarction living in Shiraz and Bandar Abbas were included in the study during 2011-2013. Demographic data were extracted from the patients’ hospital records. Data w...

Background: Cardiac complications due to iron overload are the most common cause of death in patients with thalassemia major. The aim of this study was to compare iron chelation effects of deferoxamine, deferasirox, and combination of deferoxamine and deferiprone on cardiac and liver iron load measured by T2* MRI. Methods: In this study, 108 patients with thalassemia major aged over 10 years...

conclusions there was no meaningful relationship between the mortality rate of patients with mi who were either opium-dependent or non-opium-dependent. the number of re-hospitalizations due to heart problems was meaningfully higher in the opium-dependent patients; hence, educating people and training them on the destructive effects of opium, specifically in patients with heart conditions is hig...

Implicit defined surfaces of scalar fields (isosurfaces) are a common entity in biomedical, scientific and engineering science. Polygonising an isosurface permits hardware assisted rendering and simplified geometric operations such as surface analysis and area computation. This paper introduces a novel algorithm for computing isosurfaces for scalar fields defined over (potentially curvilinear) ...

the effect of opium addiction on the appearance of different types of arrhythmias after acute myocardial infarction (ami) has been assessed in few studies. this study is aimed to determine the effect of opium on post-mi arrhythmia and also to address the differences in the appearance of different types of arrhythmias after ami between opium addicted and non-addicted patients. in this comparativ...

background: we sought to evaluate the efficacy and safety of the different trade forms of streptokinase available in our country, namely heberkinasa (heberbiotec, havana, cuba) and streptase (aventis behring gmbh, marburg, germany). methods: we conducted a double-blind randomized clinical trial to compare the two streptokinase formulations, i.e. heberkinasa (hbk) or streptase (stp), in patients...

background: our study aimed at substantiating the recent claim of myo-cardial complications in severe malaria by experimentally inducing severe plasmodium falciparum infection in a humanized mouse model employed as human surrogate. methods: twenty five humanized mice were inoculated with standard in vitro cultured p. falciparum and blood extracts collected from the inner cardiac muscles of infe...

introduction: attenuation correction is a useful process for improving myocardial perfusion spect and is dependent on activity and distribution of attenuation coefficients in the body (attenuation map). attenuation artifacts are a common problem in myocardial perfusion spect. the aim of this study was to compare the effect of attenuation correction using different attenuation maps and different...
