Figure 3 Kaplan-Meier survival curves (considering death as an end point) in patients with a positive pharmacologic stress echo test separated on the basis of the extent of the inducible ischemia identified by the delta wall motion score index (WMSI) set at 0.37. The survival is worse for larger variations of WMSI; Delta WMSI >0.37 versus Delta WMSI <0.37.
