De Virgilio et al identified prognostic factors for a patient who is undergoing an endovascular repair of an abdominal aortic aneurysm. The authors are from Harbor-UCLA Medical Center in Torrance, California.
Parameters identified by multivariate analysis:
(1) number of risk factors for cardiac (coronary artery) disease
(2) 2 or more days in the ICU after surgery ("longer" stay)
(3) STEMI (ST elevated MI) in the perioperative period (defined on page 906)
Risk factors for cardiac disease:
(1) age > 70 years
(2) history of angina
(3) history of MI or Q wave on ECG
(4) diabetes mellitus
(5) congestive heart failure
