Chest pain pathway: from ER, ECG and troponin to the next test

Works through suspected ACS step by step: STEMI or STEMI equivalents, very high-risk features, the ESC 0h/1h hs-troponin algorithm with assay-specific cut-offs (hs-cTnT Elecsys, hs-cTnI Architect, or another assay) and NSTE-ACS invasive timing. Once ACS is ruled out, it uses the ESC 2024 clinical likelihood of obstructive CAD and the 2021 AHA/ACC chest pain categories to choose between deferring tests, CCTA, exercise ECG, stress echo (exercise or dobutamine), SPECT/PET, stress CMR and invasive angiography. It checks each test against the patient's contraindications, replaces CCTA with functional imaging when CCTA is unsuitable, and lists when angiography is indicated despite a normal troponin.

STEMI equivalents: posterior MI, De Winter T waves, and LBBB or paced rhythm meeting Sgarbossa criteria. See the STEMI equivalents tool.
