The new definition of MI after revascularization of SCAI differs in several respects from that of the universal definition of MI procedure in 2012 , which was
drafted by a joint working group representing the ESC , ACC, AHA , and the
World Heart Federation. Among the major differences are:
1 . creatine kinase - MB
SCAI recommends creatine kinase - MB, rather than troponin elevation to define MI procedure.
2 . injury amount:
SCAI The proposal requires a greater amount of injury procedure to meet the definition of " clinically relevant MI
e.g " 10x the upper limit of normal for CK- MB (or CK- MB is not available , a rise 70 times in troponin ) against 5 x ULN for troponin in the universal definition.
3 . Evidence of ischemia:
SCAI The proposal does not require evidence of ischemia , whereas the universal definition requires " ischemic context" (ie , chest pain , ECG changes , angiographic signs of a procedural complication or a new abnormal wall motion ) to meet the definition of MI .
