Key result
Cardiac troponin I levels measured 24 hours after cardiac surgery independently predicted 30-day mortality (OR 1.14 per 10 microg/L; 95% CI 1.05 to 1.24; P=0.002), as well as long-term mortality.

May support postoperative troponin monitoring for risk stratification; leaves open whether targeting levels improves outcomes.

Do postoperative cardiac troponin I levels predict mortality in patients undergoing cardiac surgery?
Effect estimate: OR 1.14 (95% CI 1.05 to 1.24)
p-value: p=0.002
Cardiac troponin I levels measured 24 hours after cardiac surgery are independent predictors of short-, medium-, and long-term mortality.
Croal et al. (2006) conducted a cohort in Cardiac surgery (n=1,365). Cardiac troponin I (cTnI) measurement was evaluated on Mortality at 30 days (OR 1.14, 95% CI 1.05 to 1.24, p=0.002). Cardiac troponin I levels measured 24 hours after cardiac surgery independently predicted 30-day mortality (OR 1.14 per 10 microg/L; 95% CI 1.05 to 1.24; P=0.002), as well as long-term mortality.
