Key result
CPET parameters predict postoperative inotrope requirement and 30-month survival in AAA repair patients.
Why the study?
The ability of cardiopulmonary exercise testing (CPET) to predict early and mid-term outcomes in patients undergoing abdominal aortic aneurysm repair was evaluated.

Does cardiopulmonary exercise testing predict early and late outcomes in patients with large abdominal aortic aneurysms?
Cardiopulmonary exercise testing parameters, specifically anaerobic threshold and ventilatory equivalents for oxygen, can predict mid-term survival and early postoperative outcomes in patients with large abdominal aortic aneurysms.
Thompson et al. (2011) conducted a cohort in Abdominal aortic aneurysm (AAA) (n=102). Cardiopulmonary exercise testing (CPET) vs. Detsky score, APACHE II score, and VPOSSUM was evaluated on 30-day and mid-term outcomes (including postoperative inotrope requirement, ICU length of stay, and 30-month survival). Cardiopulmonary exercise testing parameters predicted postoperative inotrope requirement (p=0.018) and 30-month survival (p=0.02) in patients assessed for abdominal aortic aneurysm repair.
