Key result
Post-operative day 1 cardiac troponin I levels independently predicted 5-year mortality after CABG (HR 1.42; 95% CI 1.14-1.76 for each 10 microg/L increase; P=0.009), whereas ECG criteria did not.
Why the study?
Does post-operative day 1 cardiac troponin better predict 5-year mortality and hospital length of stay compared to ECG and CK-MB in patients undergoing CABG?

Muehlschlegel et al. (2009) conducted a cohort in Coronary artery bypass graft (CABG) surgery (n=545). Cardiac troponin I (cTnI) levels vs. Electrocardiogram (ECG) and creatinine kinase MB was evaluated on 5-year mortality (HR 1.42, 95% CI 1.14-1.76, p=0.009). Post-operative day 1 cardiac troponin I levels independently predicted 5-year mortality after CABG (HR 1.42; 95% CI 1.14-1.76 for each 10 microg/L increase; P=0.009), whereas ECG criteria did not.
