although lightning is an uncommon phenomenon in nature; it can cause many destructive incidents. in the event of a lightning strike, multiple organs particularly the cardiovascular systems are at risk of injury. short-term mortality depends on its cardiac effects. in this paper, the authors report the development of myocardial infarction and pericardial effusion after lightning injury, a typica...

aluminum phosphide (alp) is a highly effective rodenticide which is used as a suicide poison. herein, a 24 year-old man who’d intentionally ingested about 1liter of alcohol and one tablet of alp is reported. acute myocardial infarction due to alp poisoning has been occurred secondary to aip poisoning. cardiovascular complications are poor prognostic factors in alp poisoning

background treatment of patients with acute myocardial infarction (ami) is time related, so delay in treatment could affect prognosis. recognizing pre-hospital or in-hospital delays in initiating treatment and reducing these factors is very efficacious in treatment of these patients. results 35.7% patients arrived during one hour of symptom onset, and 7.9% arrived after 24 hours. patients havin...

introduction: cardiac remodeling after myocardial infarction, is associated with progressive ventricular dysfunction and cardiovascular death. the purpose of this study was to examine the effect of endurance exercise training on morphological changes in rat heart tissue following experimental myocardial infarction. materials and methods: rats used in this experiment (8-10 weeks old, 235 ± 5 g b...

a discrete mibi avid lung lesion was found in cinematic views of myocardial perfusion imaging (mpi) of a 59 year-old woman. interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. mpi was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  she had no past...

background: we investigated whether the lungheart ratio parameter (lhr) can be used to identify the optimum cut off frequency for butterworth filter in 99mtc myocardial spect imaging. materials and methods: this study involved a cardiac phantom system consisting of cardiac insert in which 1.10 cm cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc c...

conclusions a significant proportion of coronary atherosclerotic plaques in cadavers with confirmed acute myocardial infarction were detected to be infected with cytomegaloviruses while no infections of c. pneumoniae and h. pylori were detected. patients and methods sixty cadavers in two equal groups were analyzed. acute myocardial infarction group included cadavers with acute myocardial infarc...

Effects of Doxycycline on Cx43 Distribution and Cardiac Arrhythmia Susceptibility of Rats after Myocardial Infarction Abstract: This study aimed to observe the effects of doxycycline (DOX) on gap junction remodeling after MI and the susceptibility of rats to cardiac arrhythmia. The proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal...

Abstract Introduction: Myocardial Infarction, also known as heart attack, normally occurs due to such causes as smoking, family history, diabetes, and so on. It is recognized as one of the leading causes of death in the world. Therefore, the present study aimed to evaluate the performance of classification models in order to predict Myocardial Infarction, using a feature selection method tha...

discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...
