Background
Cardiopulmonary exercise testing (CPET) provides an objective assessment of functional capacity. The aim of this study was to assess whether preoperative CPET identifies patients at risk of early death following elective open and endovascular abdominal aortic aneurysm (AAA) repair.
Method
Prospective data were collected from a pilot study between September 2005 and February 2007, and from all patients who underwent CPET before elective AAA repair at two vascular centres between February 2007 and November 2011. Symptom‐limited, maximal CPET was performed on each patient. Univariable and multivariable analyses were used to identify risk factors for 30‐ and 90‐day mortality.
Results
Some 415 patients underwent CPET before elective AAA repair. Anaerobic threshold (AT), peak oxygen consumption (peak V̇
Conclusion
An AT below 10·2 ml per kg per min, peak V̇
