Clinical studies documenting relationship between non-invasive exercise variables and prognosis in chronic heart failure (CHF) patients undergoing symptom-limited cardio-pulmonary exercise testing (CPET)
| Reference | No. of patients | Mean VO2peak (ml/kg per min) | Event rate (%) | CPET variables related to outcome |
| Osada et al. (1998) [35] | 500 | 17.3 ± 5.7 | 26 | Peak SBP and percent achieved of predicted VO2peak |
| Robbins et al. (1999) [39] | 470 | 13.0 ± 7.0 | 15 | Peak VE/VCO2 and low HR response |
| Williams et al. (2001) [49] | 219 | 23.0 ± 9.2 | 12 | Non-invasive peak cardiac power |
| Cohen-Solal et al. (2002) [50] | 175 | 20.3 ± 5.6 | 16 | Circulatory power: ‘surrogate of cardiac output' |
| Scharf et al. (2002) [51] | 154 | 18.8 ± 0.4 | 21 | Non-invasive exercise cardiac power |
