background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...

the present study was undertaken to compare the in hospital results of coronary artery bypass graft (cabg) with (on pump) or without (off pump) cardiopulmonary bypass (cpb). data were collected on all first-time isolated cabgs with saphenous vein and/or artery grafts at shahid madani hospital in tabriz-iran, between 2006 and 2009. age and clinical profile were marched between on pump and off pu...

measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

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: cardiac output (co) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. co is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. hence, measuring co has always been a matter of interest to researchers and clinicians. sev...

Introduction: Stroke is known as a common cause of disability all over the world. Stroke prognosis estimation has always been a topic of interest. In this study, it was tried to investigate the prognostic value of laboratory findings of complete blood count in a systematic review. Methods: In this systematic review, literature from Medline via (PubMed, Ovid) Embase, Scopus, Cochrane Library, a...

introduction: ischemic stroke is a serious neurological disease and a leading cause of death and severe disability in the world. a key component of the mediterranean diet is olive oil, which contains compounds with antioxidant and anti-inflammatory effects. in this regard, the aim of the present study was to investigate the effect of olive oil on the ischemic damages and the inflammatory pathwa...

background: acute coronary syndrome is a life-threatening condition. considerable doubts exist over the effects of this disease on patients’ quality of life. the aim of this study was to survey quality of life and its influencing factors in patients with acute coronary syndrome. methods: a convenience sample of 300 patients with acute coronary syndrome was drawn from shahid beheshti hospital, k...

Introduction: TRPV1 is a non-selective cation channel with high permeability to calcium ions, and is also involved in the development of neurogenic and inflammatory pain. The increase in intracellular calcium plays a role in worsening of stroke. In the present study we investigated the effect of (AMG9810) TRPV1 receptor antagonist on stroke outcome in the permanent middle cerebral artery occlus...

Background: Prolong hospitalization after a stroke is associated with increased cost, higher risk of complications, and adverse effects.  Objectives: The purpose of this study was to determine the length of stay and its related factors among stroke patients admitted to one of the educational and therapeutic centers in the north of Iran. Materials & Methods: In this descriptive-analytic study,...
