Why the study?
Are intraoperative radial arterial systolic, diastolic, mean, and pulse pressures associated with myocardial and acute kidney injury after noncardiac surgery?
Are intraoperative radial arterial systolic, diastolic, mean, and pulse pressures associated with myocardial and acute kidney injury after noncardiac surgery?
Intraoperative systolic, mean, and pulse pressure hypotension are comparably associated with postoperative myocardial and renal injury, highlighting them as potentially modifiable risk factors.
Supports prioritizing systolic/mean/pulse pressure monitoring over diastolic; leaves open whether targeted interventions reduce injury.
Systolic, mean, and pulse pressure hypotension were comparable in their strength of association with myocardial and renal injury. In contrast, the relationship with diastolic pressure was poor. Baseline factors were much more strongly associated with myocardial and renal injury than intraoperative blood pressure, but pressure differs in being modifiable.
