Figure 1 Study Algorithm
In this diagnostic algorithm, patients in the multi-slice computed tomography (MSCT) group with normal scans were eligible for immediate discharge. Patients with severe stenosis on MSCT (over 70%) were referred for invasive angiography, whereas those with intermediate lesions or nondiagnostic scans were referred for nuclear stress scans. Patients in the standard diagnostic group underwent nuclear stress scans and were eligible for discharge if normal or referred for invasive angiography if abnormal. SOC = standard of care diagnostic evaluation.
