Primary Outcome Measures:
  • To evaluate whether there is a change in management practice pattern after Corus™ CAD [ Time Frame: Up to 7 days ] [ Designated as safety issue: No ]

    Change in management pattern after Corus™ CAD will be measured by the number of subjects with medical management downgrade or upgrade within the following predefined categories:

    1. No further cardiac testing or treatment
    2. Medical therapy for angina or non-cardiac chest pain
    3. Stress testing with or without imaging
    4. CT angiography
    5. Invasive cardiac catheterization

Estimated Enrollment: 200
Study Start Date: November 2010
Study Completion Date: June 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   21 Years and older
