Objectives. Determine outcome of the 2005 appropriateness use criteria (AUC) for SPECT in a diverse population of patients and physicians. Background. AUC for SPECT were the first cardiology document to identify 52 clinical indications for imaging, 49 of them for stress SPECT. AUC have been proposed as cornerstone of responsible use of perfusion imaging.(More)
BACKGROUND Ischemic left ventricular (LV) dysfunction may occur after exercise but is regarded as uncommon after vasodilator stress. We evaluated the prevalence of LV dysfunction after adenosine stress in relation to reversible perfusion defects and angiographic coronary artery disease (CAD). METHODS AND RESULTS We studied 86 patients referred for(More)
Increased cardiovascular morbidity and mortality in patients with type 2 diabetes is well established; diabetes is associated with at least a 2-fold increased risk of coronary heart disease. Approximately two-thirds of deaths among persons with diabetes are related to cardiovascular disease. Previously, diabetes was regarded as a "coronary risk equivalent,"(More)
BACKGROUND Previous studies have identified a downstream referral age and gender bias for invasive coronary anatomy evaluation after single-photon emission computed tomography myocardial perfusion imaging (SPECT MPI). The present study evaluates if such bias still persists despite advancements in SPECT MPI and angiography. We hypothesized that women and(More)
I read with great interest the recently published study by Calnon et al. (1), which analyzed the clinical outcome of patients who underwent dobutamine stress single-photon emission computed tomography (SPECT) Tc-99m-sestamibi imaging. Two aspects of this study are rather intriguing, and deserve further examination. First, the annual “hard” cardiac event(More)
OBJECTIVES To compare major adverse cardiac event (MACE), downstream resource utilization, and direct cost of care for low-risk chest pain patients observed in the clinical decision unit (CDU) with exercise treadmill testing (ETT) and with stress-only myocardial perfusion imaging (sMPI). BACKGROUND CDUs are poised to increase efficiency and resource(More)
