1. Cardiology Private Practice (Coordinator located in cardiology) Patient visits cardiologist Cardiologist schedules imaging examination Patient schedules cardiology visit for stable chest pain = potential point of coordinator interaction. Coordinator can get names from scheduler, call patient in advance. Coordinator can meet with patient already contacted, consent patient to RESCUE Trial and randomize.

2. Cardiology Academic (Coordinator located in academic cardiology office) Patient visits cardiologist Cardiologist schedules imaging examination Patient schedules cardiology visit for stable chest pain = potential point of coordinator interaction. Coordinator can get names from scheduler, call patient in advance, but may be only for certain OMT- favored cardiologists only. Coordinator can meet with patient already contacted, consent patient to RESCUE Trial and randomize.

3. Radiology Academic (Coordinator located in radiology) = potential point of coordinator interaction. Coordinator can get names from scheduler, if permission granted by certain cardiologists, then call patient in advance. If permission granted by cardiologist, coordinator can meet with patient already contacted, consent patient to RESCUE Trial and randomize. SPECT or CCTA Schedule Patient visits cardiologist Cardiologist schedules imaging examination Patient schedules cardiology visit for stable chest pain Coordinator can get names from CCTA or SPECT schedule.

4. Radiology Private Practice (Coordinator located in radiology) = potential point of coordinator interaction. Cardiology office can send schedule or names of suitable individuals.
