As a marker of myocardial injury, troponin level correlates with adverse outcomes following myocardial infarction (MI). We hypothesized that patients with higher preoperative troponin level would have increased morbidity and mortality following CABG. While a positive preoperative troponin correlates with worse outcomes following CABG, risk adjustment eliminates much of the short term predictive value of this biomarker. Peak troponin level does not influence outcomes following CABG and is a poor predictor of events when STS predictive models are used.
