Using Duke Activity Status Index (DASI) to Select Optimal Cardiac Stress Tests
NCT00907855 · View on ClinicalTrials.gov ↗
Study Summary
Cardiac stress testing with functional nuclear imaging is an invaluable technique in the diagnostic and prognostic evaluation of patients with known or suspected ischemic heart disease. Selection of the appropriate type of nuclear stress test: exercise stress Myocardial Perfusion Imaging (MPI) versus pharmacologic stress MPI is crucial for not only diagnostic accuracy and prognostic evaluation, but also for sound clinical decisions and resource utilization. The Duke Activity Status Index (DASI) is a 12-item questionnaire that utilized self-reported physical work capacity to estimate peak metabolic equivalents (METs) and has been shown to be a valid measurement of functional capacity. The investigators hypothesized that the DASI may be the screening tool that evaluates functional capacity and guides selection of the optimal stress MPI study.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00907855
The ClinicalTrials.gov registry entry for NCT00907855 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 200 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is NYU Langone Health, which has 1,204 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Ischemic Heart Disease appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00907855 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
