Brady et al evaluated risk factors for 30-day mortality following elective repair of an abdominal aortic aneurysm. These can help to identify patients who may benefit from more aggressive management of risk factors prior to surgery. The authors are from the MRC Clinical Trials Unit in London.
Patient selection: elective repair of an abdominal aortic aneurysm at age 60 to 80 years of age
Parameters:
(1) age of the patient in years
(2) FEV1 in liters
(3) serum creatinine in µmol/L

A patient with pulmonary or renal dysfunction may benefit from interventions to improve organ function before and after the surgery.
