introduction: cardiac complications, including heart failure, are the most important secondary ones of the thalassemia major disease, which manifests itself in adolescence and early adulthood. appropriate, low cost diagnostic tools available as well as knowing its related factors are the most important components of therapy in these patients, given the importance of these complications, or by e...

Left ventricular hypertrophy is an important diagnostic and prognostic finding in children with cardiovascular disease, but there are currently no well established criteria for its determination by M-mode echocardiography. Three hundred thirty-four subjects, aged 6 to 23 years, who were free of cardiovascular disease were studied. Left ventricular mass was calculated using echocardiographic mea...

M-mode echocardiography was used to estimate left ventricular wall mass in 136 older normal subjects (Group I: 78 men and 58 women, ages 20 to 97 years) and 105 younger normal subjects (Group II: 52 male and 53 female subjects, ages 1 day to 23 years). Echocardiographic left ventricular mass (in grams) was estimated from the following formula: left ventricular mass = 1.05 ([ left ventricular in...

BACKGROUND Obesity is linked to increased left ventricular mass, an independent predictor of mortality. As a result of this, understanding the determinants of left ventricular mass in the setting of obesity has both therapeutic and prognostic implications. Using cardiovascular magnetic resonance our goal was to elucidate the main predictors of left ventricular mass in severely obese subjects fr...

background: severe and prolonged physical training is associated with morphological and physiological cardiac changes, often termed as the “athlete’s heart”. echocardiographic features peculiar to elite iranian athletes have not been previously described. the aim was to examine the echocardiographic characteristics of highly trained iranian athletes involved in three different sports.   methods...

AIMS The significance of left ventricular hypertrophy in hypertension is well documented, being an independent risk factor for cardiovascular morbidity and mortality. Normal values for left ventricular mass and partition values for left ventricular hypertrophy come from measurements obtained by fundamental echocardiography. Secondary harmonic imaging improves definition of cardiac borders. We h...

introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...

stress-induced cardiomyopathy or takotsubo cardiomyopathy is a recently increasing diagnosed disease manifested by transient apical or mid left ventricular dilation and dysfunction. this sign is similar to acute myocardial infarction but without significant coronary artery stenosis. there are important and essential differences between takotsubo cardiomyopathy and acute myocardial infarction in...
