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.
