Figure 1 (a) Death rates for patients with and without myocardial viability treated by revascularization or medical therapy. There is 79.6% reduction in mortality for patients with viability treated by revascularization (p < 0.0001). In patients without myocardial viability, there was no significant difference in mortality with revascularization versus medical therapy. (b) Same data as (a) with comparisons based on treatment strategy in patients with and without viability. Annual mortality was lower in revascularized patients when viability was present versus absent (3.2% vs. 7.7%, p < 0.0001). Annual mortality was significantly higher in medically treated patients when viability was present versus absent (16% vs. 6.2%, p = 0.001). Revasc. = revascularization.
