OBJECTIVES We sought to relate left ventricular ejection fraction (EF), end-systolic volume index (ESVI) and infarct size (IS), as measured in a single randomized trial, to six-month mortality after myocardial infarction (MI) treated with thrombolysis. BACKGROUND These three prognostic indicators have never been compared in the same study group. METHODS Radionuclide angiographic and single-...

PURPOSE Assessment of left ventricular function is important in patients with heart disease. We hypothesized that regional wall motion assessed qualitatively by cine magnetic resonance imaging (MRI) can predict the left ventricular ejection fraction (EF). METHODS The correlations between MRI EF and the American Society of Echocardiography (ASE) score index and a modified ASE score index were ...

BACKGROUND The relationship between whole spectrum of Ejection fraction (EF) and cardioembolic stroke (CES) outcome has not been fully described yet. Notably, it remains unclear whether borderline EF (41∼49%) is related with poor outcome after CES. We sought to evaluate whether lower ejection fraction and borderline EF could predict the outcome in patients with CES. METHOD AND RESULTS We eval...

This paper outlines an algorithm to segment images on the short-axis view of the heart, obtained from multislice and multi-phase MR (Magnetic Resonance). Using the data from the segmentation of the slices, the ejection fraction of the heart is calculated for the given sequence. Segmentation is achieved by first filtering the images using Adaptive Smoothing, which smoothes the image without shif...

background: we compared the outcomes in patients with a low ejection fraction (ef) and multivessel coronary artery disease (cad) who either underwent coronary artery bypass grafting (cabg) or received medical treatment (mt) after a viability study via dobutamine stress echocardiography (dse). methods: we considered patients with cad and left ventricular ejection fraction (lvef) <40% who were re...

AIMS The goal of this study was to test whether peculiarities of left ventricular (LV) regional function place limits on the validity of ejection fraction (EF) as a measure of the myocardial functional state. METHODS AND RESULTS Transthoracic and transoesophageal data from patients with a variety of cardiac conditions were used for analysis of LV regional function. The focus was on the effect...

HEART FAILURE (HF) WITH preserved ejection fraction (EF) accounts for more than 50% of the total HF population. Community-based cohort studies have shown that mortality rates are similar in HF with preserved EF compared with HF with reduced EF, but data from large clinical trials point toward a better outcome in HF with preserved EF. This may indicate that comorbidities that are typically exclu...

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...
