Type 5 Periprocedural (post-SAVR, TAVR or CABG) MI (48 h after the index procedure)
- In patients with normal baseline CK-MB: The peak CK-MB measured
within 48 h of the procedure ≥10 the local laboratory ULN or
CKMB ≥5 ULN with one or more of the following:
- New pathologic Q-waves in ≥2 contiguous leads
- New persistent LBBBc
- Flow-limiting angiographic complications in a major epicardial vessel or >1.5 mm diameter branch
- Substantial new loss of viable myocardium on imaging related to the procedure
- In the absence of CK-MB measurements and a normal baseline cTn, a
cTn (I or T) level measured within 48 h of the procedure rises to
≥70 the local laboratory ULN or ≥35 ULN with one or more of the
following:
- New pathologic Q-waves in ≥2 contiguous leads
- New persistent LBBBc
- Flow-limiting angiographic complications in a major epicardial vessel or >1.5 mm diameter branch
- Substantial new loss of viable myocardium on imaging related to the procedure
- In patients with elevated baseline CK-MB (or cTn): The CK-MB (or
cTn) rises by an absolute increment equal to those levels
recommended above from the most recent pre-procedure level plus
new ECG changes as described.
