introduction anabolic-androgenic steroids (aas), a synthetic derivate of testosterone, have become a popular drug among athletes and bodybuilders to enhance muscle mass and improve the athletic performance. many pathological effects such as hepatic and endocrine dysfunction, behavioural changes and cardiovascular complications have been reported. case report within these ast ones, we find an in...

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...

We used first-pass radionuclide angiocardiography to assess filling fraction during the first third of diastole, peak filling rate and peak filling rate during the first third of diastole as indexes of left ventricular diastolic performance at rest and after upright bicycle exercise in 32 normal patients and 68 patients with coronary artery disease. The mean filling fraction was unchanged from ...

THLIE pharmacologic effects of digitalis preparations on the circulatory system have been the subject of numerous investigations in both animals and man. Recently, studies in dogs 1 and man,2' 3as well as experimental work on the proteins of the contractile element of heart muscle,4 have demonstrated that digitalis directly augments the force of myocardial contraction. Most investigations in ma...

The relationship of abnormal regional myocardial performance to left ventricular (LV) function 2-12 months following transmural myocardial infarctfon was investigated in 25 patients by quantitative biplane angiocardiography. Abnormally contracting segments (ACS) (akinetic or dyskinetic) of the LV were identified in 24 patients. Their sites correlated with the electrocardiographic locations of i...

background : androgens have been shown to have diverse effects on the cardiovascular system. the aim of this study was to compare androgenic hormone levels in patients with different left ventricular ejection fractions (ef). methods : the study population consisted of 515 consecutive men who were referred for angiographic studies and whose results of echocardiography and coronary angiography we...

background beta-2 microglobulin (b2m) is considered as a surrogate marker for middle molecule uremic toxins and a key component in dialysis-related amyloidosis. however, few studies have evaluated role of b2m in patients with chronic kidney disease (ckd). objectives the purpose of this study was to evaluate the association of plasma b2m level with some metabolic and cardiac performance factors ...

takotsubo cardiomypathy is a very rare cardiovascular syndrome leading to myocardial infarction and left ventricular dysfunction in the absence of a detectable coronary artery lesion. it is accepted as reversible left ventricular asynergy occuring typically after an intrinsic adrenergic hyperstimulation. in this report we present takotsubo cardiomyopathy in a 75-year-old patient with multiple a...
