Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...

Twenty-five patients with septic shock underwent simultaneous radionuclide ventriculography and right heart catheterization to clarify the role of the right ventricle in this syndrome. A depressed right ventricular ejection fraction (less than 38%) was present in 13 patients and was found in patients with elevated cardiac output (4 of 6 patients) and with normal or low cardiac output (9 of 19 p...

abstract objective cardiac dysfunction is a major cause of death in patients with beta thalassemia. in these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. left ventricular ejection fraction was measured in major beta thalassemia (β-th) patients to detect the relati...

introduction: although left ventricular(lv) function parameters measured by gated myocardial perfusion spect (gspect) have been validated, experimental data have revealed that the calculated the lv function parameters using gspect are affected by patient populations as well as particular acquisition and processing conditions. we tried to determine the normal values of gspect in an iranian popul...

Background: Study the correlation between the left ventricular end diastolic volume (LVEDV), ejection fraction (EF) and the development of arrhythmia. Patients and methods: Two hundreds patients with documented acute coronary syndrome and myocardial infection with dysrhythmia documented by ECG and holter monitoring assessed at the cardiac department at Baghdad teaching hospital over the period ...

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...

This case report was an attempt to present the importance of diagnostic echocardiography and closure of a patent foramen ovale in carcinoid heart disease. Herein, we present a case of a 48-year-old woman with a carcinoid metastasis presenting with tricuspid regurgitation, pulmonic stenosis, patent foramen ovale, and borderline left ventricular ejection fraction on an echocardiogram. Surgical in...

background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...
