  Aim

‘Normal’ range for cardiac troponin I (TnI) has changed with more sensitive tests, but the validity of low-level elevations is contentious. We aimed to describe the characteristics and outcome of patients with an initial TnI level 1–5 times the upper limit of normal.

Methods

Retrospective study of patients assessed for ACS with initial TnI level between 0.05–0.19 ng/ml. Data collected included demographics, clinical data, TnI levels and outcome. Primary outcome was the proportion of patients who had a serial TnI rise consistent with ACS.

Results

72 patients were studied; median age 71, median TIMI score 3, 66.7% male. 35 patients (48.6%) had a TnI rise consistent with ACS.

Conclusion

Approximately half of patients with initial TnI between 0.05–0.19ng/ml had a TnI rise consistent with ACS. An initial TnI in this range is not, of itself, indicative of ACS. Clinical decision-making should be guided by clinical features and serial TnI measurement.
