Figure 2 Association of age at CABG with survival. The depiction is a nomogram (solution to the equation) of the multivariable hazard function. The solid curves enclosed by their dashed confidence limits represent, from top to bottom, 30-day, 3-year, 10-year and 15-year survival. Superimposed on the nomograms is a corresponding depiction of the U.S. population life table for each time frame. The following values for risk factor variables were used: male patient, weight 77 kg, body surface area 1.95 m2, Canadian Heart Class III angina, no use of digitalis nor diuretics, one previous myocardial infarct, LV wall motion score 7, LV end diastolic pressure 12 mm Hg, three coronary systems diseased, no left main or proximal left anterior descending (LAD) coronary disease, no inferior wall jeopardy, no history of diabetes, hypertension or smoking, elective operation with use of only vein grafts. This, in a 55-year-old patient, represents the median values for individual variables in Appendix A.
