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.
