Why the study?
Recent evidence suggests that an undetectable troponin level at ED presentation can rule out MI in low-risk patients, but accuracy at various fTIMI score cut-offs is unclear.

Jonathan M. Holmes (1953) conducted an observational in chest pain without ECG evidence of ischaemia (n=1,076). Undetectable initial troponin I (TnI) level vs. Detectable troponin I level was evaluated on diagnostic accuracy for MI of undetectable initial TnI at presentation at various fTIMI scores.
