Key result
Perioperative myocardial infarction after coronary artery bypass grafting was associated with a significantly higher 30-day mortality rate (11.5% vs 0.4%, OR 15.44) compared to patients without PMI.
Why the study?
Perioperative myocardial infarction after CABG contributes to in-hospital morbidity and mortality, but its clinical significance on long-term outcome remains inadequately addressed.

PMI signals high short-term mortality after CABG but comparable long-term survival; leaves open whether prevention strategies alter outcomes in prospective data.

Odds Ratio: 15.44 (95% CI 6.89–34.57)

Perioperative myocardial infarction after CABG is associated with significantly increased 30-day mortality and short-term complications, but long-term survival among 30-day survivors is comparable to those without PMI.
Heiðarsdóttir et al. (2024) conducted a cohort in Coronary artery bypass surgery (CABG) (n=1,446). Perioperative myocardial infarction (PMI) vs. No perioperative myocardial infarction was evaluated on 30-day mortality (OR 15.44, 95% CI 6.89-34.57, p=<0.001). Perioperative myocardial infarction after coronary artery bypass grafting was associated with a significantly higher 30-day mortality rate (11.5% vs 0.4%, OR 15.44) compared to patients without PMI.
