Periprocedural myocardial infarction in chronic total occlusion: The challenge of precise diagnosis and prognostication
Key Points
- Myonecrosis following PCI is a frequent impediment that may impact cardiac prognosis.
- The frequency of periprocedural myocardial infarction (PMI) in CTO-PCI is dependent on MI definition (biomarker and threshold), lesions characteristics, and PCI course.
- This study identified predictors of PMI during CTO-PCI and it showed that PMI and peak CK-MB level were associated with worse clinical outcomes.
