Figure 4 Predicted 1-year total and death/reinfarction event rates (with standard error bars) based on total (A) and ischemic (B) perfusion defect size (PDS) and their combination (C). The isobars in C (range 10% to 75%) depict risk for any event. For a patient with a 30% nonischemic PDS, the predicted event rate is 11% (solid circle), versus 25% if the defect is all ischemic (open circle). LV = left ventricle.
