Definitions of peri-procedural myocardial infarction and the association with one-year mortality: Insights from CHAMPION trials.

ABSTRACT:

Background

Controversies exist over the appropriate definition for peri-procedural myocardial infarction (PPMI) and its association with mortality. This study aims to evaluate one-year survival following percutaneous coronary intervention (PCI) and the association of different definitions of PPMI with survival among patients with stable angina (SA) or acute coronary syndrome (ACS) in the contemporary era.

Methods

We used data from the CHAMPION PLATFORM and CHAMPION PCI trials of patients undergoing PCI and conducted univariable and multivariable Cox proportional hazard regression models to evaluate mortality risk during the first year after PCI. A blinded events committee adjudicated suspected PPMI defined by biomarker elevations ≥3× the upper limit of normal (ULN) or new Q-
