Background: We assessed the current status of treatment strategy in ST-segment elevation myocardial infarction (STEMI) with multivessel disease (MVD) in real world practice, focusing on the benefit of staged percutaneous coronary intervention (PCI). Methods and Results: From the CREDO-Kyoto AMI Registry, 2,010 STEMI patients with MVD undergoing primary PCI were analyzed. Only 96 patients (4.8%) received acute multivessel PCI, and the majority of patients (n=1,914, 95.2%) had culprit-only PCI acutely. After excluding 699 patients (acute multivessel PCI, Killip class >= 3, age >= 90 years, coronary artery bypass grafting within 90 days, or clinical events within 90 days), 681 MVD patients underwent staged PCI for angiographically significant non-culprit lesions within 90 days (staged PCI group), while 630 MVD patients received primary PCI only (culprit-only PCI group). The cumulative 5-year incidence of and adjusted risk for all-cause death were significantly lower in the staged PCI group compared with the culprit-only PCI group (9.5% vs. 16.0%, P<0.001; HR, 0.69; 95% CI: 0.50-0.96, P=0.03). The risks for MI and any coronary revascularization favored the staged PCI strategy. Conclusions: The staged PCI strategy for angiographically significant non-culprit lesions was associated with lower 5-year mortality compared with the culprit-only PCI strategy in STEMI patients with MVD who underwent primary PCI.
