The UK EVAR trial used a modified customized probability model (mCPM) for evaluating patients undergoing repair of an abdominal aortic aneurysm (AAA).
EVAR = EndoVascular Aneurysm Repair
The original CPI was reported by Kertai et al.
Parameters:
(1) previous history of cardovascular disease (myocardial infarction, cardiac revascularization, angina, severe valvular disease, significant arrhythmia)
(2) congestive heart failure
(3) therapy for hypertension
(4) observed FEV1 as percent of predicted
(5) serum creatinine in µmol/L
(6) therapy with a beta-blocker
(7) therapy with a statin

total score =
=SUM(points for all 7 parameters)
Interpretation:
• minimum score: -25
• maximum score: 57
• The higher the score the worse the patient's fitness.
