Figure 1 Kaplan-Meier event-free survival rates for the composite end point of death, re-infarction, or ischemia-driven target vessel revascularization. Patients with successful percutaneous coronary intervention (PCI) had a low major adverse cardiac events rate after hospital day 4, whereas patients with unsuccessful PCI continued to experience a significantly higher rate of major adverse cardiac events up to 7 to 10 days.
