Early post-MI surgery associated with high reinfarction rates; leaves open optimal timing with modern perioperative care.
What is the incidence of postoperative myocardial reinfarction in patients with a previous myocardial infarction undergoing general anesthesia, and how does the timing of surgery affect this risk?
The risk of postoperative myocardial reinfarction is exceptionally high (37%) when surgery under general anesthesia is performed within three months of a previous myocardial infarction.
Sait Tarhan (1972) studied this question.
