Key result
Elevated post-CABG biomarkers correlate with MRI-quantified perioperative myocardial infarct mass.
Why the study?
To evaluate whether elevated biochemical marker levels after CABG correspond to the amount of peri-operatively infarcted myocardium quantified by post-operative MRI.
Do elevated biochemical markers after CABG correlate with the amount of peri-operatively infarcted myocardium quantified by MRI?
Observational (n=23)
Do elevated biochemical markers after CABG correlate with the amount of peri-operatively infarcted myocardium quantified by MRI?
Elevated post-operative cardiac biomarkers (CK-MB, troponin I and T) accurately reflect the mass of peri-operative myocardial infarction following CABG as quantified by MRI.

Biomarkers track post-CABG infarct mass on MRI; hypothesis-generating and should not change practice without larger validation.
Johnny Steuer (2004) conducted an observational in Coronary artery bypass grafting (n=23). Elevated biochemical marker levels was evaluated on Amount of peri-operatively infarcted myocardium quantified by MRI. Elevated biochemical markers after CABG correlated with the mass of peri-operatively infarcted myocardium quantified by MRI, with infarctions found in 18 of 23 patients.
