Bracco Diagnostics, Inc. announced in June that Kinevac (sincalide) production had been halted and that the product will not be available for at least 2 months. Kinevac is the only intravenous cholecystogogue drug approved by the U.S. Food and Drug Administration (FDA) to stimulate gallbladder contraction. It is thus useful for calculation of gallbladder ejection fraction (GBEF) to diagnose chr...

In this study we describe the ejection fraction response to upright exercise using first-pass radionuclide angiocardiography in a group of 60 patients with chest pain, normal coronary arteriograms and normal resting ventricular function. A wide range of resting function (heart rate and ejection fraction) and exercise function (heart rate, ejection fraction, peak work load and estimated peak oxy...

This investigation was designed to determine the role of echocardiography in the assessment of left ventricular function in patients with significant coronary arterial disease. Satisfactory echocardiograms were obtained in 43 patients with coronary arterial disease. The ventriculographic ejection fraction was determined by the area length method. The echocardiographic left ventricular end-diast...

patients with coronary artery disease and left ventricular dysfunction have high mortality with non surgical (medical) treatment. coronary artery bypass grafting improves survival and the quality of life. recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. the aim of this study was to survey the result of coronary artery bypass grafting with of...

BACKGROUND Simpson ejection fraction, wall motion score index, atrioventricular (AV) plane displacement and fractional shortening are all established formal echocardiographic methods for the assessment of left ventricular systolic function. Visually estimated (eyeballing) ejection fraction may be considered somewhat more subjective, although shown to correlate well with radionuclide ventriculog...
