Design, rationale, and populations of an international outcomes and utilization study of pharmacologic stress SPECT myocardial perfusion imaging in contemporary practice

The design offers a unique opportunity to study the characteristics of patients referred for SPECT imaging over a period of time consistent with the laboratories' usual practices, provides an up-to-date PS safety registry, and allows assessment of the prognostic value of PS SPECT MPI across a wide number of covariables, as well as relationships between patient and population characteristics, SPECT MPI results, and clinical outcomes.
