Figure 1 One-year survival estimates of "SHould we emergently revascularize Occluded Coronaries for cardiogenic shocK" (SHOCK) trial patients by left ventricular (LV) ejection fraction. Survival rates increase with increasing ejection fraction (p = 0.001), and this relationship is independent of treatment assignment (interaction p = 0.778). For each level of ejection fraction, survival is better for emergency revascularization (ERV) patients. Data frequency for ERV and initial medical stabilization (IMS) patients is shown by fringe on top and bottom of the plot, respectively. Three patients identified as ineligible after randomization due to severe mitral regurgitation or LV free rupture were excluded.
