Primary Outcome Measures:
  • Diagnostic Failure [ Time Frame: 30 days ] [ Designated as safety issue: No ]
    Diagnostic failure is defined by a composite of need for additional downstream testing (anger SPECT, MPI PET, stress echocardiography or coronary CT angiography) within 30 days or a coronary angiogram with no stenoses greater than or equal to 50% severity using quantitative coronary angiography.


Secondary Outcome Measures:
  • Necessity to proceed to a rest image [ Time Frame: 30 days ] [ Designated as safety issue: No ]
    The first of 4 secondary end-points is the need to proceed to a rest image.

  • Necessity for additional downstream testing [ Time Frame: 30 days ] [ Designated as safety issue: No ]
    The second of four secondary endpoints the need for additional downstream testing within 30 days to address the same clincial reason for the innitial referral for stress-onoly imaging, in the absence of any changes in clincial status between tests.

  • Coronary Angiography [ Time Frame: 60 to 90 days ] [ Designated as safety issue: No ]
    The third of four secondary end-points is the occurrence of coronary angiography with no stenoses greater than or equal to 50% severity using quantitative coronary angiography.

  • Determine optimal performance of the Spectrum Dynamics camera system for stress only imaging [ Time Frame: 60 to 90 days ] [ Designated as safety issue: No ]
    The fourth of four secondary endpoints is to determine optimal performance of the Spectrum Dynamics camera system for stress only imaging: upright imaging alone, supine imaging alone, or both in terms of primary and secondary endpoints
