Why the study?
The predictive value of changes in MAP alone without reference to absolute MAP is poor for predicting intraoperative hypotension, whereas linear extrapolation of MAP is closer to clinical practice.
Does LepMAP better predict intraoperative hypotension than ΔMAP alone in adult patients undergoing high-risk non-cardiac surgery?
Population
83 adult patients undergoing high risk non-cardiac surgery
Comparison
LepMAP vs ΔMAP alone
Design
Retrospective diagnostic accuracy study at two tertiary University Hospitals

May support simple MAP-trend alerts for near-term hypotension but should not yet change practice; challenges ΔMAP as HPI benchmark and leaves open ML incremental value.
Does LepMAP better predict intraoperative hypotension than ΔMAP alone in adult patients undergoing high-risk non-cardiac surgery?
A simple linear extrapolation of mean arterial pressure provides reliable real-time prediction of intraoperative hypotension 1 and 2 minutes before its occurrence, outperforming changes in MAP alone.
