The implication of traditional subjective initial clinical evaluation on identifying frail patients and stratifying surgical risk versus objective assessment of cardiorespiratory fitness by referencing cardiopulmonary exercise testing (CPET) remains unknown. 1 Bailey and colleagues demonstrated that such a subjective assessment of patients' frailty underestimated patients ’ surgical risk as compared with objective assessments using CPET. 2 They recommend utilizing CPET, instead of traditional subjective assessments, for preoperative risk stratification in patients scheduled for high ‐ stakes surgery such as open thoracoabdominal aortic aneurysm repair. Several concerns have been raised. The in the results between the subjective and objective assessments. 2 predict postoperative clinical outcomes in their study. Did the objective assessments using CPET significantly stratify clinical outcomes following the CPET for all candidates for thoracoabdominal
