Relationship Between Infarct Artery, Myocardial Injury, and Outcomes After Primary Percutaneous Coronary Intervention in ST-Segment-Elevation Myocardial Infarction.

ABSTRACT:

Background

The extent to which infarct artery impacts the extent of myocardial injury and outcomes in patients with ST-segment-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention is uncertain.

Methods and results

We performed a pooled analysis using individual patient data from 7 randomized STEMI trials in which myocardial injury within 30 days after primary percutaneous coronary intervention was assessed in 1774 patients by cardiac magnetic resonance (n=1318) or technetium-99m sestamibi single-photon emission computed tomography (n=456). Clinical follow-up was performed at a median duration of 351 days (interquartile range, 184-368 days). Infarct size and outcomes were assessed in anterior (infarct vessel=left anterior descending) v
