Regarding Perioperative Myocardial Infarction

[anes]

Maybe an easy/dumb question.

What does peri-operative myocardial infarction mean?
If a patient has an MI 2 weeks out from non-cardiac surgery, is this considered peri-operative?
If a patient has an MI on POD2 after being discharged home... is this peri-operative MI?
Can a person who had an MI the day BEFORE surgery be considered to have a peri-operative myocardial infarction?

Is there an actual definition and cutoff for periop MI?

Thanks in advance

Periop generally means during and within 30 days after the surgery.

With regard to cardiac risk, surgical interventions can be divided into low-risk, intermediate-risk, and high-risk groups with estimated 30-day cardiac event rates (cardiac death and myocardial infarction [MI]) of <1%, 1%–5%, and >5%, respectively (see table below).

This is the European paper, by the way; like you, I am too lazy to look for the specific US reference (but I know 30 days is the cutoff most studies use). 😛

So POD2 is periop, 2 weeks after is periop, the day before is not.
