Abstract
- Aims: To assess the significance of creatine kinase (CK)-MB elevations in outcomes of patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) who have undergone coronary artery bypass grafting (CABG) surgery.<br />Methods and Results: This analysis includes data from 26 465 patients with NSTE ACS enrolled in four major trials. In total, 4626 (17.5%) of patients had CABG within 30 days. Patients were excluded if CK-MB was elevated within 24 h before surgery and there was no CK-MB measured after surgery. Overall, 4401 patients were included in these analyses. The incidence of mortality increased with peak CK-MB ratios of 0-1, >1-3, >3-5, >5-10, and>10x the upper limit of normal measured at the local lab (P<0.001 across categories): 1.1, 2.8, 2.4, 3.1, and 10.8% in hospital; 1.1, 3.0, 2.9, 3.5, and 10.2% at 30 days; and 1.6, 4.4, 4.7, 6.0, and 10.9% at 180 days. Multivariable predictors of 6-month mortality included age, heart rate and randomization, peak CK-MB ratio, time to CABG, prior angina, signs of congestive heart failure and randomization, three- and two-vessel coronary disease, enrolment infarction, ST-segment depression at enrolment, female sex, experimental treatment, and systolic blood pressure.<br />Conclusion: CK-MB elevations after CABG are independently associated with increased risk of mortality in patients with NSTE ACS.
