Figure 7 Prognostic Implications of Myocardial Viability Testing

The data are derived from meta-analysis of 3,088 patients with coronary artery disease and left ventricular dysfunction who underwent viability testing. Death rates for patients with and without myocardial viability treated by revascularization or medical therapy are shown. In patients with viable myocardium, there is 79.6% reduction in mortality among those who were treated with revascularization (p < 0.0001). In contrast, among patients without evidence of viable myocardium, there was no significant difference in mortality with revascularization versus medical therapy.
