periprocedural myocardial infarction
Myocardial injury occurring in temporal association with invasive cardiac procedures.
Full Definition
Periprocedural myocardial infarction (PMI) refers to myocardial injury that occurs during or shortly after invasive cardiac procedures such as percutaneous coronary intervention or cardiac surgery. PMI is typically diagnosed based on elevation of cardiac biomarkers (particularly troponin) above specific thresholds in conjunction with clinical or imaging evidence of new myocardial damage. The definition and thresholds for PMI have evolved with advances in biomarker sensitivity, and different criteria exist for PCI-related versus surgical procedures. PMI is associated with increased short- and long-term mortality, making its recognition and documentation crucial in procedural reports.
Usage
Usage note: Commonly abbreviated as PMI in cardiology contexts; ensure distinction from other MI types.
