Conclusions BCIS have performed the first randomized trial of elective vs. bailout IABP in patients with poor LV function and severe coronary disease We did not find evidence that Elective IABP to support high risk PCI is associated with a reduction in MACCE at hospital discharge 12% in the no-planned group required emergency IABP, supporting the important role of provisional IABP use Patients with poor LV function and severe coronary disease treated by PCI appear to have acceptable in-hospital and 6 month mortality (1.3% and 6%)
