Conceptual Proposal to Use Cardiac Troponin in COVID-19

Baseline measurements can facilitate stage classification (52) and initial triage (steps 1 and 2), and serial measurements help with short- and long-term risk stratification (step 3). This information is likely to be most beneficial in those in whom disease stage and risk status is uncertain, where cTn can help with decisions about triage and level of care. ARDS = acute respiratory distress syndrome; CRP = C-reactive protein; CXR = chest x-ray; NT-proBNP = N-terminal pro–B-type natriuretic peptide.
