Why the study?
Does increased preoperative arterial pulse pressure predict 30-day and 1-year all-cause mortality in patients undergoing lower extremity arterial bypass surgery?
Population
556 patients who had infrainguinal arterial bypass surgery at a single center over a 6-year period
Comparison
Increased preoperative arterial pulse pressure vs Lower preoperative arterial pulse pressure
Design
Cohort
Follow-up
1 year

Preoperative pulse pressure should not inform mortality risk assessment in lower extremity bypass; leaves open prospective validation in other cohorts.
Does increased preoperative arterial pulse pressure predict 30-day and 1-year all-cause mortality in patients undergoing lower extremity arterial bypass surgery?
Preoperative arterial pulse pressure is not associated with 30-day or 1-year all-cause mortality after lower extremity arterial bypass surgery.
