May heighten perioperative MI risk after AAA repair; leaves open whether catecholamine modulation improves outcomes.
Observational (n=18)
Does abdominal aortic aneurysm repair increase plasma catecholamine levels in patients undergoing surgery?
Patients undergoing abdominal aortic aneurysm surgery experience significantly elevated serum catecholamine levels, supporting a hormonal component to perioperative myocardial ischemia.
Riles et al. (1993) conducted an observational in Abdominal aortic aneurysm (n=18). Abdominal aortic aneurysm surgery vs. Preoperative baseline was evaluated on Plasma epinephrine and norepinephrine levels. Abdominal aortic aneurysm surgery was associated with significantly increased plasma epinephrine levels during and after surgery, and increased norepinephrine levels at 24 hours postoperatively.
