| Measure | Description | Time Frame |
|---|---|---|
| Diagnostic Failure | 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. | 30 days |
| Measure | Description | Time Frame |
|---|---|---|
| Necessity to proceed to a rest image | The first of 4 secondary end-points is the need to proceed to a rest image. | 30 days |
| Necessity for additional downstream testing | 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 | 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. | 60 to 90 days |
| Determine optimal performance of the Spectrum Dynamics camera system for stress only imaging | 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 | 60 to 90 days |
