Left ventricular (LV) cavity dilation during stress myocardial perfusion imaging has been associated with multivessel disease, and may be an independent prognostic marker in addition to perfusion(More)
UNLABELLED Tissue attenuation results in nonuniform myocardial perfusion images with significant sex differences. New SPECT imaging protocols to correct attenuation are currently under investigation.(More)
OBJECTIVES Theophylline has been shown to delay the onset of myocardial ischemia and to prolong exercise duration. The present study was done to evaluate the mechanisms and actions of intravenous(More)
BackgroundPatients with congestive heart failure (CHF) have increased ventilatory equivalent for carbon dioxide (Ve/VCO2), which may contribute to the symptom of exerciseinduced hyperpnea. We have(More)
