The aim of this prospective cohort study was to examine correlation between the postprocedural absolute rise of cardiac troponin (cTn-I), cardiac troponin T (cTn-T), and creatine phosphokinase MB (CK-MB), and predictive value of each marker for the long-term cardiac events following successful percutaneous coronary interventions. ⋯ Although the cTn-I is found to be relatively more sensitive cardiac marker, cTn-T can be used as an alternative assay with significant correlation, concordance, and prospective value. Both troponins have predictive value for long-term event free survival; particularly 4-fold increase is associated with worse event free survival.
