Management guideline for trial intervention arm
| CTCA result | Troponin result | Trial treatment recommendation |
|---|---|---|
| Obstructive disease: stenosis ≥70% | Positive or negative | 1. ACS and secondary preventative therapies 2. Invasive coronary angiography (ICA) ± revascularisation |
| Moderate non-obstructive disease: stenosis 50–69% | Positive | 1. ACS and secondary preventative therapies 2. Consider ICA if uncertainty about the presence of obstructive coronary artery disease or functional testing |
| Moderate non-obstructive disease: stenosis 50–69% | Negative | 1. Secondary preventative therapies 2. Consider ICA if uncertainty about the presence of obstructive coronary artery disease or functional testing |
| Mild non-obstructive disease: stenosis <50% | Positive | 1. Consider ACS and secondary preventative therapies 2. Consider alternative cause of chest pain and troponin rise |
| Mild non-obstructive disease: stenosis <50% | Negative | 1. Discharge with no further follow-up 2. Consider secondary preventative therapies |
| Normal (no evidence of CAD) | Discharge with no further follow-up |
