Troponin T Levels stratified by surgical procedure, risk profile and cross-clamp time
Trends of troponin levels at the three time points were analyzed in patients who underwent CABG vs. Non-CABG patients. Similar trends were found with significantly lower troponin levels with DNC in patients underwent isolated CABG (P = .018), All CABG group (P = .004) and Non-CABG group (P = .001) Supplemental Table S3 , Figure S1, Figure S2 and Figure S3 . Likewise, in higher risk group patients, DNC was associated with significantly lower troponin levels (P = .001) as well as lower CPB (P =.01) and cross-clamp times (P = .02),Supplemental Table S3 and Figure S4 .
The trend of lower troponin levels was examined based on ischemia time. Similar trends of significant lower troponins level with DNC were found in patients with aortic cross-clamp time more than 120 minutes (P =.001). Details are included in the Supplement Figure S5, Figure S6, and Supplemental Table S4 and Table S5.
