Cooperman et al developed an equation for predicting the risk of cardiovascular complications following major vascular surgery in patients with peripheral vascular disease.
Parameters used for equation:
(2) congestive heart failure
(4) myocardial infarction
(5) cerebrovascular accident
(6) abnormal electrocardiogram (ECG)
congestive heart failure
= (0.46 * (points for angina)) + (1.02 * (points for congestive heart failure)) + (0.62 * (points for arrhythmia)) + (0.64 * (points for myocardial infarction)) + (1.15 * (points for cerebrovascular accident)) + (1.25 * (points for abnormal electrocardiogram)) – 3.81
In the original paper, this is used as:
probability of cardiovascular complications =
However, it probably should be used as:
= 1 / (1 + EXP((-1) * X))
• The score was developed in 1978.

Purpose: To evaluate a person with peripheral vascular disease for cardiovascular risk prior to vascular surgery using the score of Cooperman et al.
