Abstract:: OBJECTIVES: We aimed to assess the prognostic value of postprocedural creatine kinase myocardial band (CK-MB) and cardiac troponin (cTn) in patients with non-ST-segment elevation myocardial infarction (NSTEMI). BACKGROUND: Whether postprocedural CK-MB or cTn is a better biomarker to stratify the risk after percutaneous coronary intervention (PCI) remains unknown. METHODS: This study included 2,077 patients with NSTEMI undergoing early PCI. Peak postprocedural values of CK-MB and high-sensitivity cTn T (hs-cTnT) were analyzed. The primary outcome was 3-year mortality. RESULTS: The median values of peak postprocedural CK-MB and hs-cTnT were 18.3 U L-1 and 0.140 µg L-1 , respectively. Overall, 211 patients died during follow-up. There were 129 deaths in patients with CK-MB >the median value and 82 deaths in those with CK-MB ≤the median value (Kaplan-Meier estimates of 3-year mortality, 18.9% and 14.0%, respectively; hazard ratio [HR] = 1.52, 95% confidence interval [CI] 1.16-2.01; P < 0.001). There were 134 deaths in patients with hs-cTnT >the median value and 77 deaths in patients with hs-cTnT ≤the median value (Kaplan-Meier estimates of 3-year mortality, 19.9% and 13.2%, respectively; HR = 1.90 [1.44-2.52]; P < 0.001). After adjustment, peak postprocedural CK-MB (adjusted HR = 1.05 [1.02-1.07], P < 0.001 for each 24 U L-1 increment) and hs-cTnT (adjusted HR = 1.12 [1.01-1.25], P = 0.037 for each unit higher log hs-cTnT) remained independently associated with the risk of 3-year mortality. The C-statistic(s) of the model with CK-MB and hs-cTnT were 0.789 [0.757-0.817] and 0.793 [0.762-0.821], respectively (P = 0.585). CONCLUSION: In patients with NSTEMI undergoing early PCI, peak postprocedural CK-MB and hs-cTnT are independently associated with the risk of 3-year mortality. © 2017 Wiley Periodicals, Inc.
