pulmonary arterial hypertension (pah) is a progressive disease with high morbidity and mortality rates. research has shown that pah has a prevalence rate of 10-79% in thalassemia major patients. this cross-sectional study was carried out in 2014 to determine the prevalence and risk factors of pah in all thalassemia major patients of over 18 years of age in ilam, iran. a cardiologist measured sy...

BACKGROUND Patients with known or suspected coronary disease are often investigated to facilitate risk assessment. We sought to examine the cost-effectiveness of strategies based on exercise echocardiography and exercise electrocardiography. METHODS AND RESULTS We studied 7656 patients undergoing exercise testing; of whom half underwent exercise echocardiography. Risk was defined with the Duk...

BACKGROUND In electrocardiography (ECG), QT is the interval between the onset of Q wave to the end of the T wave. This interval may be a sign of changes in the ventricular structure in hematologic disorders such as thalassemia major. OBJECTIVES The main goal of this study was to compare the diagnostic value of corrected QT dispersion (QTcd) and QT dispersion (QTd) with left ventricular mass (...

echocardiography is a non-invasive diagnostic technique which provides information on cardiac morphology, function, and hemodynamics. it is the most frequently used cardiovascular diagnostic test only after electrocardiography. in less than five decades, the evolution in this technique has made it the basic part of cardiovascular medicine. herein, the evolution of various forms of echocardiogra...

BACKGROUND Many noninvasive tests exist to determine whether patients should undergo coronary angiography. The routine use of coronary angiography without previous noninvasive testing is typically not advocated. OBJECTIVE To determine the cost-effectiveness of diagnostic strategies for patients with chest pain. DESIGN Cost-effectiveness analysis. DATA SOURCES Published data. TARGET POPU...

in order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive m-mode and doppler echocardiography, an analytic study was designed in a university hospital in sari. we have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. peak flow velocity in ...

Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...

The accuracy of electrocardiography, M-mode echocardiography and two-dimensional echocardiography in predicting left ventricular hypertrophy was compared in 50 patients who came to autopsy within 6 months after the studies were performed. Several methods for determining left ventricular hypertrophy were examined for each of the three techniques. M-mode echocardiography was technically adequate ...

abstract background prevention of myocardial siderosis is a key step to reduce rate of mortality in thalassemic patients. our objective was to study association between echocardiography parameters and serum ferritin level in patients with major thalassemia. materials and methods sixty-six patients with major thalassemia were studied in amir kabir hospital, arak, iran. serum ferritin levels were...

BACKGROUND Hypertension is an important modifi able cardiovascular risk factor. Left ventricular hypertrophy - the marker of hypertension, has emerged as an independent risk factor that can be detected by electrocardiography (ECG)and echocardiography (ECHO). OBJECTIVE Correlation of electrocardiography and echocardiographically detected left ventricular hypertrophy in hypertensive patients. ...
