background: stroke is the third leading cause of invalidism and death in industrialized countries. there are conflicting reports about the effects of angiotensin ii on ischemia-reperfusion brain injuries and most data have come from chronic hypertensive rats. in this study, hypotensive and non-hypotensive doses of candesartan were used to investigate the effects of angiotensin ii at1 receptor b...
Background and aims:Nowadays cardiovascular disorders are the most common cause of death in worldwide. Several studies have shown that ischemic cardiovascular diseases are more common in drivers, especially professional drivers, but underlying causes have not beencompletely understood.Methods:This study was a cross sectional, descriptive-analytic study. 1120 professional divers who worked with ...
Myxoma may cause systemic embolization and frequently presents as ischemic stroke. There has been debates whether it is safe to use recombinant tissue plasminogen activator (rt-PA) in patients with cardiac myxoma who are presented with ischemic stroke at emergency department. we describe a young case of atrial myxoma with initial presentation of acute cerebral infarction symptoms who was treate...
The aim of this study was evaluation of triglyceride and cholesterol levels in patients with ischemic stroke admitted in neurology ward during one year (99-2000).Hyperlipidemia is one of the risk factor for atherosclerosis and ischemic stroke . Several stu...
Background and Aim: Presence of ischemic changes on the anterior surface of heart and AV block worsen the prognosis of acute Inferior Mycocardial Infarction (MI). The rate of mortality increases with the occurrence of AV block in inferior MI.The aim of this study was to predict and diagnose acute Inferior MI in patients with AV block based on ECG and clinical features.Patients and Methods: ...
Background: Hyperglycemia after acute stroke is a common finding that has been associated with an increased risk of death. For the last several years, it was believed that post-stroke hyperglycemia may worsen brain infarction in animal models. According to previous studies, the anti-inflammatory effect of insulin has a protective role on ischemic tissues. Glucose-insulin-potassium (GIK) infusio...
Background: Among different mechanisms, oxidative stress has a possible role in neural injury in cerebrovascular events. Objectives: Assessment the oxidants-antioxidants imbalance in ischemic and hemorrhagic strokes. Materials and Methods: Serum level of malondialdehyde, the main marker of lipid peroxidation, and total antioxidant capacity were measured in a group of 48 stroke patients consis...
Background and purpose: Ïn order to determine the presence of anticardiolipin (acl) antibodies in patients with ischemic events, a case control study was designed and performed. Materials and methods: 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 persons with no evidence of ischemic heart disease were selected for this study. Plasma samples were asses...
Introduction: Arteriovenous fistulas (AVF) make chronic hemodialysis easy, but the complications are unpredictable. Ischemic neuropathy due to arterial insufficiency is one of the most important complications of AVF. This study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. Methods: In this cross-sectional study, 37 hemodialysis ...
Introduction: During the recent years, vitamin D deficiency was determined as a risk factor for cardiovascular diseases. The purpose of this study was to evaluate the association of vitamin D with ischemic heart disease in the city of Hamadan. Methods: A case control-study was performed with 72 patients with ischemic heart disease, which had been confirmed by angiography in the case group. V...
