The usefulness of the modified steep ramp test as a practical exercise test for preoperative risk assessment in patients scheduled for pancreatic surgery
Authors' conclusion
The modified SRT is a valid short-term practical exercise test to preoperatively assess aerobic capacity in patients undergoing pancreatic surgery.
Study context
- Population
- Patients scheduled for pancreatic surgery who performed cardiopulmonary exercise testing (CPET) and the modified steep ramp test (SRT) within 14 days preoperatively21 females
- Participants
- 48 patients
- Comparison
- Modified SRT vs CPET for preoperative aerobic capacity
- Outcome
- Correlation between modified SRT WRpeak and CPET VO2peak (criterion validity); ROC classification of fit vs unfit
Methodological detailscriterion validity
- Criterion validity
Performance
As reported in the abstract
| Test or model | ρ with CPET VO2peak | R with CPET VO2peak | WRpeak cutoff | AUC (VO2peak cutoff) | AUC (VO2 at ventilatory anaerobic threshold (VAT) cutoff) |
|---|---|---|---|---|---|
| Modified SRT | 0.865 | 0.926 | 2.095 W/kg | 0.948 | 0.814 |
