High Troponin I in Patients Following Off-pump Coronary Artery Bypass Grafting.

ABSTRACT:

Background

Blood troponin I (TnI) concentrations, the reasons for increases in TnI after coronary artery bypass grafting (CABG) and the effects of TnI on short- and long-term outcomes are not well understood.

Methods

Patients undergoing off-pump CABG at Anzhen Hospital between 2011 and 2022 were reviewed. Data on peak postoperative TnI and high-sensitivity (hs) TnI were collected, and patients were divided into a high TnI group (TnI ≥10 ≥g/l or hsTnI ≥10,000 pg/ml) and low TnI group. Baseline characteristics, graft flow, perioperative outcomes and long-term mortality were compared between the two groups.

Results

In all, 19,196 patients were included in the study (median age 63 years; interquartile range [IQR] 57-68 years; 14,423 (75.1%) male). Compared with the low Tn
