Key result
Prior myocardial infarction was associated with a 3.8% rate of perioperative reinfarction, compared to a 0.4% incidence of new myocardial infarction in patients without prior infarction.
Why the study?
Does prior myocardial infarction increase the risk of perioperative myocardial reinfarction during anesthesia and surgery?

No takes yet. Share an insight, caveat, or question.
The risk of perioperative myocardial infarction remains significantly elevated in patients with a prior infarct, showing little improvement over historical rates despite advances in monitoring.
Schoeppel et al. (1984) conducted an editorial in Perioperative myocardial infarction. Prior myocardial infarction vs. No prior myocardial infarction was evaluated on Perioperative myocardial infarction. Prior myocardial infarction was associated with a 3.8% rate of perioperative reinfarction, compared to a 0.4% incidence of new myocardial infarction in patients without prior infarction.
