Authors' conclusion

In a large, unselected hospital population, in 91.4% of whom there was no clinical indication for testing, cTnI concentration was independently associated with medium-term cardiovascular and non-cardiovascular mortality in the statistical model tested.

Study context

Population
Consecutive in-hospital and outpatient patients who had a blood test for any reason at a large teaching hospital, with hs-cTnI measured regardless of clinical indication18,282 (91.4%) no indication for cardiac troponin I (cTnI)
Participants
20,000 participants
Exposure
cTnI above vs not above upper limit of normal (ULN)
Outcome
Medium-term mortality
Follow-up
Median 809 days
