Figure 6.

Shows survival free from cardiac ischemic events in patients who either did not undergo subsequent revascularization (A) or who did undergo revascularization (B). Survival curves for the 3 types of possible contrast dipyridamole echocardiography response (normal, isolated reversible myocardial perfusion defect [MPD], or both MPD+wall motion abnormality [WMA]) are shown in the upper panels while mid and lower panels dichotomize response based on wall motion or myocardial perfusion assessment. While test results have a clear prognostic value in patients who subsequently did not undergo revascularization, such value is lost in patients subsequently revascularized, indirectly indicating that revascularization acts as an outcome‐modifier.
