To the Editor: In their study, Dr Domanski and colleagues demonstrated that myocardial necrosis, as measured by CK-MB or troponin elevation in the first 24 hours following CABG surgery, was associated with increased mortality.1 Among other covariates in their multivariable model, CK-MB ratio was the strongest predictor of 30-day mortality following CABG surgery.
