Figure 2 Kaplan-Meier curves of hard event free survival according to DASE. Hard event free survival was good and similar (
2 = 2.76, p = 0.1) in patients with sustained improvement and scar alone and poor (
2 = 83.4, p < 0.0001) in patients with inducible ischemia. Hard event free survival was also similar (
2 = 0.12, p = 0.73) in the subsets with biphasic (Biphasic) and worsening wall motion at peak dose only (WWM Peak Only), but events tended to occur earlier in those with biphasic responses. Hard event free survival was better (
2 = 44.5, p < 0.0001) in patients with inducible ischemia treated with revascularization.
