Key result
Intraoperative systolic blood pressure decreases of 41 to 50 and >50 mmHg lasting at least five minutes increased the odds of 30-day postoperative myocardial infarction by 3- and 20-fold, respectively.
Why the study?
Does intraoperative hypotension increase the risk of postoperative myocardial infarction in noncardiac surgical patients?
Case-Control
Yes
Does intraoperative hypotension increase the risk of postoperative myocardial infarction in noncardiac surgical patients?
Odds Ratio: 20
Intraoperative hypotension with systolic blood pressure decreases >40 mmHg from baseline for at least 5 minutes is associated with a markedly increased risk of postoperative myocardial infarction.
Prolonged intraoperative SBP drops >40 mmHg for ≥5 min warrant vigilance; leaves open optimal targets pending prospective trials.

Intraoperative hypotension can result in adverse postoperative outcomes. In a multicenter study that matched noncardiac surgical patients with myocardial infarction (MI) within 30 postoperative days with controls without MI after surgery, systolic blood pressure decreases of 41 to 50 and >50 mmHg from preoperative baseline and lasting for at least five minutes increased the odds for postoperative MI by 3- and 20-fold, respectively [1]. In another multicenter retrospective study, odds for a composite outcome (acute MI, acute ischemic stroke, or mortality) increased... You do not currently have access to this content.

A 2021 study conducted a case-control in Noncardiac surgery. Intraoperative systolic blood pressure decreases of 41 to 50 and >50 mmHg from preoperative baseline lasting ≥5 minutes vs. No such intraoperative blood pressure decrease was evaluated on Postoperative myocardial infarction within 30 days (OR 20). Intraoperative systolic blood pressure decreases of 41 to 50 and >50 mmHg lasting at least five minutes increased the odds of 30-day postoperative myocardial infarction by 3- and 20-fold, respectively.
