objective: ischemic preconditioning (ipc) is an endogenous phenomenon that can induce ischemic tolerance (it) in variety of organs such as brain. in this study, we examined the intermittent and prolonged normobaric hyperoxia (ho) on neurologic deficit scores, infarct volume, and superoxide dismutase activity. materials and methods: the rats were divided to four main groups. first two main grou...

Background: Some recent studies have shown that troponin may have a Prognostic value in patients with ischemic stroke. This study seeks to to evaluate the prognostic value of troponin on 3 months mortality and recurrence in patients with ischemic stroke. Method: In this study 63 patients with ischemic stroke were evaluated. Embolic and lacunar stroke were excl...

background: embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. transesophageal echocardiography (tee) is superior in identifying potential cardiac sources of emboli. due to insufficient data on tee findings in ischemic stroke in iran, the present study was done to evaluate tee in d...

stroke is the third cause of death in the world after the cancer and cardiovascular disease. . it has been shown that stroke in northeast of iran occurs approximately one decade earlier than in western countries. reasons for the high stroke incidence among persian are not yet clear. it is the first gene-association study in persian population, which determines the relationship between 25 gene v...

  Background: Embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. Transesophageal echocardiography (TEE) is superior in identifying potential cardiac sources of emboli. Due to insufficient data on TEE findings in ischemic stroke in Iran, the present study was done to evaluate TEE in...

Background & Aims: Sleep disorders are common complains in patients with cerebral stroke; studies on these issues are limited. We aimed to evaluate the sleep changes in patients with supratentorial ischemic stroke. Methods: In this cross sectional study, 38 patients (19 patients in supratentorial ischemic stroke group and 19 people in control group) were evaluated. Total sleep time, sleep effic...

conclusions opium was not identified as a risk factor of ischemic stroke. a more extended survey considering further confounding factors is recommended. background one of the supposed risk factors of ischemic stroke is opium addiction, while the researches about its prevalence among patients with stroke are limited. objectives the aim of this study was comparing the prevalence of opium addictio...

myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. the possibility of their early detection has made them of great importance for emergency medicines. detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. we report experience of a rar...

background: in patients with acute ischemic cerebral infarction, thrombolytic therapy using intravenous tissue plasminogen activator (iv?tpa) necessitates precise documentation of symptoms’ onset. the aim of this study was to identify major barriers related to the iv?tpa injection in such patients. materials and methods: between 2014 and 2015, patients with definitive diagnosis of acute cerebra...
