Journal ArticleDOI
Mental stress and the induction of silent myocardial ischemia in patients with coronary artery disease.
Alan Rozanski,C N Bairey,David S. Krantz,Joseph H. Friedman,Kenneth J. Resser,M Morell,S Hilton-Chalfen,L Hestrin,J. Bietendorf,Daniel S. Berman +9 more
TL;DR: Emotionally relevant mental stress may be an important precipitant of myocardial ischemia--often silent--in patients with coronary artery disease and further examination of the pathophysiologic mechanisms responsible for myocardian ischemie induced by mental stress could have important implications for the treatment of transient myocardia.
Journal Article
"Upward creep" of the heart: a frequent source of false-positive reversible defects during thallium-201 stress-redistribution SPECT.
Joseph H. Friedman,K. Van Train,J. Maddahi,Alan Rozanski,F. Prigent,J. Bietendorf,Aaron B. Waxman,Daniel S. Berman +7 more
TL;DR: The frequency of this source of false-positive 201Tl studies can be reduced by delaying SPECT acquisition until 15 min postexercise, which is probably related to a transient increase in mean total lung volume early following exhaustive exercise.
Journal ArticleDOI
Patient motion in thallium-201 myocardial SPECT imaging. An easily identified frequent source of artifactual defect.
Joseph H. Friedman,Daniel S. Berman,K. Van Train,Ernest V. Garcia,J. Bietendorf,F. Prigent,Alan Rozanski,Aaron B. Waxman,Jamshid Maddahi +8 more
TL;DR: A method was developed for detection and correction of motion from SPECT images using a Co–57 point source placed on the lower anterior chest, an area remaining in the camera's field of view throughout imaging, that provides a simple practical approach for the detection of patient motion.
Journal ArticleDOI
Rest and treadmill exercise first-pass radionuclide ventriculography: validation of left ventricular ejection fraction measurements.
John D. Friedman,John D. Friedman,Daniel S. Berman,Daniel S. Berman,Hosen Kiat,Hosen Kiat,J. Bietendorf,J. Bietendorf,Mark Hyun,Mark Hyun,Kenneth Van Train,Kenneth Van Train,Fan Ping Wang,Fan Ping Wang +13 more
TL;DR: This procedure now provides the option for combining the information of peak treadmill exercise LVEF with measurements of exercise myocardial perfusion from the same injection of radioactivity.
Journal ArticleDOI
Thallium-201 stress-redistribution myocardial rotational tomography: Development of criteria for visual interpretation
F. Prigent,Jamshid Maddahi,Ernest V. Garcia,John D. Friedman,Kenneth Van Train,J. Bietendorf,H.J.C. Swan,Daniel S. Berman +7 more
TL;DR: In 50 consecutive patients, who underwent SPECT stress-redistribution Tl-201 imaging, a systemically developed visual interpretive criteria for perfusion abnormality on SPECT, which offered promise for improved localization of CAD.
