Key result
An immediate postoperative cardiac troponin T concentration ≥1.58 ng/mL strongly predicted a prolonged intensive care unit length of stay >24 hours after cardiac surgery (OR 5.6; 95% CI 2.9-10.8).

No
Does postoperative cardiac troponin T predict prolonged intensive care unit length of stay in patients following cardiac surgery?
Odds Ratio: 5.6 (95% CI 2.9–10.8)
Elevated immediate postoperative cTnT concentrations strongly predict the need for prolonged intensive care unit stay following cardiac surgery.
May inform early risk stratification after cardiac surgery; leaves open whether troponin thresholds should guide interventions.

Baggish et al. (2004) conducted a cohort in Cardiac surgery (n=222). Elevated postoperative cardiac troponin T (cTnT) concentration vs. Normal/lower cTnT concentration was evaluated on Prolonged intensive care unit length of stay (>24 hrs) (OR 5.6, 95% CI 2.9-10.8). An immediate postoperative cardiac troponin T concentration ≥1.58 ng/mL strongly predicted a prolonged intensive care unit length of stay >24 hours after cardiac surgery (OR 5.6; 95% CI 2.9-10.8).
