A Comparison of Outcome in Patient With and Without Undergoing Cardiopulmonary Exercise Testing (CPET).

CPET tested patients have statistically significant lower length of total and ICU stay compared to non-CPET patients. CPET is therefore a useful adjunct in selecting patients for open surgery compared to non-physiological testing. This study provides some evidence on the use of this routinely but not validated assessment tool in aortic aneurysm repair.
