Background: Because of the importance of thyroid function and its effect on different organs, such as the heart, this study was aimed to evaluate the effect of levothyroxine on cardiac function in children with subclinical hypothyroidism. Methods: This quasi-experimental study was performed on children aged 4-12 years old with diagnosis of subclinical hypothyroidism in Amirkola Children's Hosp...

Acute myocardial infarction (MI) remains a leading cause of morbidity and mortality worldwide [1]. It affects both systolic and diastolic functions [2]. In hospital complications of myocardial infarction include arrhythmia, heart failure, post infarction angina and death [2]. Conventional echocardiographic indices that are routinely applied for the estimation of cardiac function face a number o...

AIM The aim of the present study was to analyze the relationship between epicardial adipose tissue thickness (EATT) and echocardiographic parameters, such as carotid intima-media thickness (cIMT), myocardial performance index (MPI), left ventricular (LV) systolic and diastolic function, and LV mass index in adolescents with obesity. PATIENTS AND METHODS One hundred and thirty eight obese adol...

BACKGROUND Stress nuclear myocardial perfusion imaging (MPI) is an established method for diagnosis and prognosis of coronary artery disease (CAD). However, radiation exposure limits its clinical application. Magnetocardiography (MCG) has been proposed as a non-contact, rapid and non-radiation technique with high reproducibility. The aim of the study was to evaluate the diagnostic efficacy of r...

OBJECTIVES Fetal aortic valvuloplasty can improve filling and reduce afterload of the left ventricle in critical aortic stenosis. Success of an intrauterine intervention is currently measured by technical success, clinical survival and eventual postnatal biventricular physiology. In the present study we investigated the use of tissue Doppler imaging (TDI) to evaluate changes in ventricular func...

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...

OBJECTIVE This study was designed to assess right ventricular systolic and diastolic function and its relationship with grade of hepatosteatosis (HS) in non-alcoholic fatty liver disease (NAFLD) patients using conventional and tissue Doppler echocardiography. METHODS NAFLD was diagnosed in 32 individuals (15 males, 17 females; 59% were grade I HS, 41% grade II-III HS) by means of ultrasonogra...

objective: although coronary artery disease (cad) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. myocardial perfusion imaging (mpi) is reported to show ischemia in a significant number of asymptomatic diabetic patients. we studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. meth...

   The performance of a decision making unit (DMU) can be evaluated in either across-sectional or a time-series manner, and data envelopment analysis (DEA) is a useful method for both types of evaluation. The Malmquist productivity index (MPI) evaluates the change in efficiency of a DMU between two time periods. It is defined as the product of the Catch-up and Frontier-shift terms. In this pape...

Objective: Cardiac dysfunction has been reported in both cirrhotic and alcoholic patients. Our aim was to determine the relation of serum N-terminal pro-B-type natriuretic peptide (Nt-proBNP) levels myocardial performance index (MPI) disease severity nonalcoholic Patients Methods: In this prospective study including 25 patients 27 healthy controls, MPI assessed by pulsed-wave tissue Doppler ima...
