BACKGROUND Left ventricular ejection fraction (LVEF) is the most widely used parameter to evaluate the cardiac function in patients with heart failure (HF). However, the association between LVEF and contrast-induced nephropathy (CIN) is still controversial. Therefore, the aim of this study is to evaluate the association of LVEF with CIN and long-term mortality following coronary angiography (CA...

OBJECTIVES Emergency department (ED) bedside echocardiography may offer useful information on cardiac function and volume status. The authors evaluated the accuracy of emergency physician (EP) performance of echocardiography in the assessment of left ventricular ejection fraction (LVEF) and central venous pressure (CVP). METHODS The authors conducted a cross-sectional observational study at a...

AIMS Comparison of intracoronary infusion of bone marrow (BM)-derived unselected mononuclear cells (UNSEL) and selected CD34(+)CXCR4(+) cells (SEL) in patients with acute myocardial infarction (AMI) and reduced <40% left ventricular ejection fraction (LVEF). METHODS AND RESULTS Two hundred patients were randomized to intracoronary infusion of UNSEL (n = 80) or SEL (n = 80) BM cells or to the ...

Electrocardiographic gating is increasingly used for 82Rb cardiac PET/CT, but reference ranges for global functional parameters are not well defined. We sought to establish reference values for left ventricular ejection fraction (LVEF), end systolic volume (ESV), and end diastolic volume (EDV) using 4 different commercial software packages. Additionally, we compared 2 different approaches for t...

this study was performed to evaluate the tc-pyp spect role in determination of ami severity and extension. pyp spect imaging was done for 54 patients with ami, who met the who criteria. spect findings were correlated with lvef measurements. the abnormal scan was graded according to the intensity and was compared with the activity of the sternum in the same image. in addition, a segmental myocar...

BACKGROUND Heart failure (HF) disproportionately affects Native Hawaiians and Other Pacific Islanders (NHOPIs). This study examines risk factors associated with left ventricular ejection fraction (LVEF) among 151 hospitalized NHOPI HF patients enrolled at a single tertiary care hospital between June 2006 and April 2010. METHODS Enrollment criteria: (1) NHOPI by self-identification. (2) Age ≥ ...

BACKGROUND Approximately one third of patients with symptomatic aortic stenosis have reduced left ventricular ejection fraction (LVEF) before transcatheter aortic valve replacement. The incidence, predictors, and significance of early LVEF recovery after CoreValve transcatheter aortic valve replacement have not been described. METHODS AND RESULTS We studied 156 patients from the CoreValve Ext...
