^*P=0.022 for interaction of risk category and treatment

^†Use of the Stage 1 system with LVEF instead of non-inferior MI yields risk categories approximately 4 points higher to correspond to percentile groupings shown.

Timing of revascularization was not available for 59 patients

ERV=Early Revascularization (=18 hours following shock diagnosis); Revasc.=Revascularization
