The effects of troponin screening among patients undergoing acute high‐risk abdominal surgery: A retrospective cohort study
Authors' conclusion
The implementation of postoperative troponin screening was not associated with reduced mortality after AHA surgery.
Study context
- Population
- Patients undergoing acute high-risk abdominal (AHA) surgery, February 2018 to March 2021336 screened
- Participants
- 558 patients
- Exposure
- Screening vs Historical control
- Screeningn = 382
- Historical controln = 176reference
- Outcome
- Unadjusted 30-day mortality
- Follow-up
- 30 days
Methodological detailshistorical control, inverse probability treatment weighting, In the screening group, 15 (3.9%) died before first blood sampling and screening was omitted in 31 (8.1%)

Main finding
As reported in the abstract
30-day mortality (unadjusted)
- Absolute risk difference
- −2.7% (95% CI −8.7%-3.3%; p = .38)
Observational data: associations, not effects.
Further findings
Mortality at 90 days and 1 year
- Difference remained unchanged after 90 days and 1 year
Myocardial injury diagnosed among screened patients
- Myocardial injury diagnosed in 81 of the 336 patients screened
- 24.1%
- Cardiac consultation among those with myocardial injury (59 patients)
- 72.8%
- No interventions or alterations related to myocardial injury (67 patients)
- 82.7%
