CPET Prognostic Score (HFpEF) Calculator
CPET Parameters
Enter the patient's cardiopulmonary exercise testing values. The score updates automatically.
Enter all parameters
The total will be shown when all three values are valid.
| Parameter | Entered value | Points |
|---|---|---|
| Peak VO2 | — | — |
| VE/VCO2 slope | — | — |
| Peak exercise oxygen pulse | — | — |
About the CPET parameters
Cardiopulmonary exercise testing (CPET) provides measures of exercise capacity and ventilatory efficiency. Peak VO2, the VE/VCO2 slope, and oxygen pulse can contribute complementary physiological and prognostic information in heart failure.
Scoring rules implemented from the original file
| Parameter | Value | Points |
|---|---|---|
| Peak VO2 | <14 | 2 |
| Peak VO2 | 14–18 inclusive | 1 |
| VE/VCO2 slope | >35 | 2 |
| VE/VCO2 slope | 30–35 inclusive | 1 |
| Oxygen pulse (% predicted) | <70 | 2 |
| Oxygen pulse (% predicted) | 70–80 inclusive | 1 |
Values outside the listed ranges receive 0 points, following the original code. These thresholds and the combined weighting have not been confirmed as a validated HFpEF prognostic score.
