background: cardiac risk assessment with myocardial perfusion imaging (mpi) is a common practice for some elderly breast cancer patients who are candidates for operation. in rare cases the tumor may become visible in the images. case presentation: this is the report of a case with a huge slow-growing breast tumor suspicious for malignancy and presenting with methoxy-isobutyl-isonitrile (mibi) u...

introduction: to investigate 28 days survival rate following first acute myocardial infarction (ami) associated with the presence of classical risk factors and treatment modalities in gorgan, north of iran. materials and methods: our cohort including all patients hospitalized due to ami from 2010 to 2013. data were collected on demographic, prophylactic drugs and classical coronary risk factors...

repetitive episodes of brief regional ischemia have been shown to reduce the severity of life-threatening ventricular anhythrnias and infarct size that occur during prolonged occlusion of the coronary artery. this phenomenon is known as ischemic preconditioning. during studies in anesthetized, open chest wistar rats, we accidentally observed that poorly ventilated animals had a reduced severity...

background: myocardial infarction (mi) is a main cause of death and disability worldwide, whichinvolves a number of genetic, physiopathologic and socio-economic determinants. the aim of thisstudy was to assess the patterns of association between education, wealth and some other risk factorswith non-fatal mi in tehran population.methods: data derived from a second round of large cross-sectional ...

myocardial infarction (mi) is a common presentation of the ischemic heart disease. lavandula angustifolia is a herbaceous plant with antioxidative effects.this study was designed to investigate the cardioprotective effects of lavandula angustifolia essential oil against isoproterenol-induced mi in rats.the dried sample was subjected to hydrodistillation by using a clevenger and the oils were dr...

echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. it is the most frequently used cardiovascular diagnostic test after electrocardiography and chest x-ray. however, in a patient with acute chest pain, transthoracic echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation of v...

background: qt interval parameters have been suggested as a predictor of lethal arrhythmia and mortality in patients with myocardial infarction. the aim of the present study was to compare the value of qt interval indices in patients presenting with non-st-segment elevation myocardial infarction (nstemi) between a group of patients with type 2 diabetes mellitus and a nondiabetic group of patien...

background:the door-to-needle-time (dnt) is considered a standard time for scheduling thrombolysis for acute st-segment elevation of myocardial infarction and this time can be reduced by minimizing the delay in starting thrombolytic treatment once the patient has reached to the hospital. this study was carried out on a sample of iranian patients with acute myocardial infarction to determine the...

Silent myocardial infarction is a little-known phenomenon, the mechanisms of which have still remained unclear. Herein, we presented the case of a middle-aged man suffering from silent myocardial infarction who presented with homonymous hemianopia and no other major cardiovascular risk factors, except for stage 1 hypertension.

background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...
