Test sequence in each modelled strategy
| First test | Second test | Third test | |
| Strat. 1 | Exercise ECG | Stress echocardiography | Coronary angiography |
| Strat. 2 | Exercise ECG | Coronary CT angiography | Coronary angiography |
| Strat. 3 | Exercise ECG | SPECT | Coronary angiography |
| Strat. 4 | Exercise ECG | Coronary angiography | |
| Strat. 5 | SPECT | Coronary angiography | |
| Strat. 6 | Stress echocardiography | Coronary angiography | |
| Strat. 7 | Stress echocardiography | Coronary CT angiography | Coronary angiography |
| Strat. 8 | Stress cardiac MRI | Coronary angiography | |
| Strat. 9 | Coronary CT angiography | Coronary angiography | |
| Strat. 10* | Coronary angiography | Stress echocardiography | |
| Strat. 11* | Coronary angiography | SPECT |
*Strategies 10 and 11, in which invasive coronary angiography is the first test, are only considered in scenarios with high pretest probability. SPECT, single-photon emission CT.
