Study Population
This was a retrospective single institutional analysis that included adults (18 years or older) that underwent isolated, primary CABG operations at a multi-hospital health system between January 2011 and June 2018. Only patients with cardiac presentation of NSTEMI and troponin leak were analyzed. The highest (peak) measured blood serum troponin in the preoperative period was recorded for each patient. This study was approved by the Institutional Review Board at the University of Pittsburgh (MOD18120143-003, approved 3/9/2020). Due to retrospective nature of the study, patient consent was waived.
