متن کاملReference Ranges for LVEF and LV Volumes
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...
متن کاملImprovement of stress LVEF rather than rest LVEF after coronary revascularisation in patients with ischaemic cardiomyopathy and viable myocardium.
OBJECTIVE To evaluate prospectively the response of left ventricular ejection fraction (LVEF) to high dose dobutamine infusion in patients showing substantial viability, with and without improved resting LVEF after revascularisation. METHODS Before and 9-12 months after revascularisation, 50 patients with ischaemic cardiomyopathy (LVEF 32 (8)%) and substantial myocardial viability (> or = 4 v...
متن کاملLong lasting effect of physical stress on the LVEF.
BACKGROUND Animal and clinical studies have shown that exercise can deteriorate myocardial contractile function. The aim of this study was to examine whether the decrease of LVEF measured with gated SPECT lasts as long as 3 hours after exercise. MATERIAL AND METHODS 46 patients with CAD and a control group comprising 10 healthy subjects were studied. All patients underwent myocardial perfusio...
متن کاملOverestimation of the LVEF by quantitative gated SPECT in simulated left ventricles.
UNLABELLED During routine myocardial perfusion imaging, a common observation is that patients with normal cardiac function and small hearts, in particular small women, have higher left ventricular ejection fractions (LVEFs), as measured by quantitative gated SPECT (QGS) software, than anticipated, often markedly so. The goal of this project was to determine if the QGS LVEF varies with the chang...
