This study of 1,718 men with bypass surgery from 1970 to 1974 in Milwaukee
has indicated that the following factors are significantly associated with
five-year survival: left ventricular end-diastolic pressure (LVEDP), plasma
cholesterol level, coronary occlusion score, age, and left ventricular
function (LVF). The 31 men with a previous stroke had a high risk
(five-year survival was 32%). To serve as a guide to patient risk, a
logistic model is used to predict five-year survival. These probabilities
are tabulated for all combinations of LVEDP, age, LVF, occlusion score, and
plasma cholesterol level.
