BACKGROUND Three dimensional echocardiography (3DE) approaches the accuracy of cardiac magnetic resonance in measuring left ventricular (LV) volumes and ejection fraction (EF). The multibeat modality in comparison to single-beat (SB) requires breath-hold technique and regular heart rhythm which could limit the use of this technique in patients with atrial fibrillation (AF) due to stitching arti...

Heart failure with preserved ejection fraction (HFpEF) is a growing epidemiologic problem affecting more than half of the patients with heart failure (HF). HFpEF has a significant morbidity and mortality and so far no treatment has been clearly demonstrated to improve the outcomes in HFpEF, in contrast to the efficacy of treatment in heart failure with reduced ejection fraction (HFrEF).The fail...

Background Those with single ventricle circulations often have a normal ventricular volumetric ejection fraction (VV EF) which is not in keeping with their symptoms and prognosis. Recently four-dimensional flow (4Dflow) magnetic resonance imaging (MRI) has been used to extract parameters of intra-cardiac kinetic energy (KE). There has been recent interest in measuring ventricular KE in health a...

BACKGROUND The aim of the study was to assess the correlation of the selected biomarkers and collagen turn-over indices with advanced echocardiographic parameters among patients with preserved and reduced ejection fraction (EF). METHODS We included 62 patients with the symptomatic heart failure. The patients were divided in to two groups according to the evaluated ejection fraction (EF - Simp...

The ejection fraction (EF) of the left ventricle was measured by radionudide ventriculography In 64 patients during an acute cerebrovascuiar accident. Sixteen patients (12 with coronary artery disease) died within two weeks of the onset of symptoms and had only one EF measurement. In the remaining 48 patients, the EF was also measured two weeks and three months after the acute event. The ejecti...

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...

To evaluate the clinical usefulness of the first-third ejection fraction (1/3 EF) for detecting patients with coronary artery disease (CAD), resting contrast ventriculography and first-pass radionuclide angiography with a high-count-rate, multicrystal camera system were performed in 47 subjects: 22 normal controls (group 1) and 25 patients with clinically stable angina pectoris and severe CAD (...

AIMS Predicting the likely success of primary PCI to salvage potential infarcted myocardium is desirable. We compared early invasive parameters of coronary microcirculation function with the levels of circulating endothelin (ET-1) and 6-month ejection fraction after STEMI. METHODS AND RESULTS Forty-four STEMI patients underwent assessment of coronary flow reserve (CFR) and index of myocardial...

BACKGROUND Reduced ejection fraction (EF) has previously been shown to be a risk factor for adverse outcomes in patients undergoing percutaneous coronary intervention (PCI). However, with the advent of stents, procedural complications and restenosis rates have reduced dramatically. The aim of this study was to assess the association between left ventricular (LV ) ejection fraction and in-hospit...

BACKGROUND Little is known regarding the impact of diastolic function on cardiac output (CO) in patients with heart failure, particularly in patients with lower ejection fraction. This study aimed to evaluate the impact of end-diastolic pressure-volume relationship (EDPVR) on CO and end-diastolic pressure (EDP). METHODS AND RESULTS We retrospectively analyzed 1840 consecutive patients who und...
