Key result
Post-PCI troponin I elevation occurs more frequently than CK-MB elevation, detecting myocardial injury in ~19% of patients.
Why the study?
The usefulness of cardiac troponin as a marker for detecting minor myocardial injury following PCI in stable angina patients was evaluated.
Observational (n=79)
Answers are grounded in this paper and cite their sources.
Troponin monitoring may identify minor post-PCI injury in stable angina; leaves open whether it refines risk stratification or management.

Kim et al. (2002) conducted an observational in Stable angina (n=79). Cardiac troponin I (cTnI) measurement vs. CK-MB measurement was evaluated on Frequency of abnormal enzyme levels post-PCI (p=<0.01). Abnormal cardiac troponin I levels were detected in 19% of patients following percutaneous coronary intervention, a significantly higher frequency than CK-MB elevation (6%, p<0.01).
