Risk categorization after troponin measurement. (A) Distribution of patients after the initial hs-cTnT measurement: risk categories following the 0 h troponin quantification from patients presenting to the emergency department or ambulatory emergency care, defined as: Low <5 ng/L; Intermediate low 5–12 ng/L; Intermediate high 13–51 ng/L; High ≥52 ng/L. Proportion of initial tests haemolysed shown. (B) Rapid risk stratification after repeat troponin measurement into ‘Low risk’, ‘ACS possible’ or ‘ACS likely’ as per Figure 1. Bar colours correspond to colour coding of risk as depicted in Figure 1 with 2020 clear and 2021 hatched.
