STUDY OBJECTIVE To validate the practicality of focused echocardiography with A-F mnemonic performed by non-specialists in patients with suspected acute coronary syndrome (ACS). DESIGN This prospective observational study was conducted in the Emergency Room within 12 months period. Study population consisted of consecutive patients with preliminary diagnosis of an ACS. The following data were...
Background and purpose: Ësophageal cancer is one of the most lethal diseases in the world. Ït has a high prevalence in Ïran, especially in the northern provinces. The main treatment of esophageal cancer is surgical. These are two surgical Procedures for its treatment. Transhiatal esophagectomy (THË) and transthoracic esophagectomy (TTË) which are of common . Since we have no previous...
نتایج بدست آمده از این مطالعه تا حد زیادی مطابق با آمارهای ذکر شده می باشد. از جمله شایعترین محل درگیری در سل ستون فقرات که در ناحیه لومبار و توراسیک تحتانی گزارش شده است . در این مطالعه هم حداکثر محل درگیری در l2,l1 و بعد در ناحیه توراسیک تحتانی بوده و گرفتاری در بیشتر قسمتها در جنس مذکر مختصری بیشتر از مونث می باشد. نتیجه دیگری که از این بررسی بدست آمد شیوع بیشتر این بیماری در دهه 5 و 6 می با...
هدف از این تحقیق بررسی تأثیر مکملگیری منیزیم سولفات بر شاخصهای الکترومیوگرافی آستانۀ خستگی (EMGFT)، لاکتات و زمان رسیدن به واماندگی (TTE) در پی یک جلسه فعالیت هوازی دویدن روی نوار گردان تا حد واماندگی در مردان دانشگاهی غیرفعال بود. به این منظور 16 دانشجوی پسر غیرفعال (با میانگین سنی 18/1 ± 25/25 سال، قد 75/4 ± 18/176 سانتیمتر، وزن 65/25 ± 51/79 کیلوگرم) به‌طور تصادفی به دو گروه مکمل (8 ن...
Novel cyclic olefin polymers (COPs) derived from bulky cyclic olefins, tricyclodipentadiene (TCPD) and tricyclo[6.4.0.19,12]-tridec-10-ene (TTE), with high glass transition temperature (Tg), excellent thermal stability, and high transparency, have been synthesized by ring-opening metathesis polymerization (ROMP) and subsequent hydrogenation. ROMP of TCPD and TTE was carried out successfully wit...
BACKGROUND Measurement of mitral annulus (MA) dynamics is an important component of the evaluation of left ventricular (LV) diastolic function; MA velocities are commonly measured using tissue Doppler imaging (TDI). This study aimed to examine the clinical potential of a semi-automated cardiovascular magnetic resonance (CMR) technique for quantifying global LV diastolic function, using 3D volum...
BACKGROUND AND OBJECTIVES We aimed to assess the incidence and evolution of left ventricular (LV) thrombi in a high-risk population of patients with LV systolic dysfunction after anterior myocardial infarction (ant-MI). We also compared the accuracy of transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging with contrast-delayed enhancement (CMR-DE) in detecting LV thrombi. ...
BACKGROUND Triiodothyronine levels decrease in infants and children after cardiopulmonary bypass. We tested the primary hypothesis that triiodothyronine (T3) repletion is safe in this population and produces improvements in postoperative clinical outcome. METHODS AND RESULTS The TRICC study was a prospective, multicenter, double-blind, randomized, placebo-controlled trial in children younger ...
BACKGROUND Pulmonary hypertension (PH) is frequently found at the time of diagnosis of pulmonary embolism (PE). An incomplete resolution of PE can lead to chronic thromboembolic pulmonary hypertension (CTPH). Transthoracic echocardiogram (TTE) is the first step to diagnose an abnormality of the pulmonary vasculature. Based on computed tomography (CT), the Qanadli vascular obstruction index has ...
Abstract Background and Aims In chronic kidney disease (CKD), the incidence of cardiovascular (CVD) increases along with CKD progression. Although coronary artery (CAD) is one most critical CVDs, it difficult to identify CAD because its symptom usually atypical in CKD. Consequently, appropriate screening tests for CVD are important this population. Electrocardiography (ECG) transthoracic echoca...
