1. No new areas of hypokinesis on cine CMR New LGE after PCI New LGE after PCI

2. LGE new and Tn/CK-MB increase - From 9 cases with LGE (2 patients did not have postprocedural TnI) 6 were detected with TnI assay – 63% diagnostic accuracy (TnI > 2x ULN). - No linear relationship between LGE mass and TnI amount - CK-MB was less sensitive for myonecrosis detection in comparison with TnI – 4 cases from 11 – 36% with increase >1xULN; BUT only 1 case >2x ULN (9%); - No linear relationship with LGE detected mass

3. TnI assay sensitivity for LGE detection AUC 83%, sensitivity 89%, specificity 56%, p =.026 for LGE detection, when TnI >.05ng/dl
