Conclusions
In our analysis of 1,211 adult patients undergoing isolated CABG following NSTEMI, we found higher level of preoperative “peak” troponin (>1.95 ng/mL) to be associated with increased ICU time and hospital length of stay. However, there was no association with peak troponin level and short- and long-term MACCE or mortality. In sub-analysis, peak troponin >10.00 ng/mL was not associated with increased hazards for MACCE or mortality. These data argue against the utility of using preoperative troponin levels as a guide for timing of CABG in NSTEMI.
