结局指标
主要结局
Diagnostic Failure
时间窗: 30 days
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.
次要结局
- Necessity to proceed to a rest image(30 days)
- Necessity for additional downstream testing(30 days)
- Coronary Angiography(60 to 90 days)
- Determine optimal performance of the Spectrum Dynamics camera system for stress only imaging(60 to 90 days)
