An investigator-initiated, randomized, multicenter, two-arm, open-label study of consecutive patients presenting with STEMI and MVD Objectives: The present study aimed to investigate the difference in all-cause mortality after in-hospital staged PCI versus out-hospital staged PCI for ST-segment elevated myocardial infarction STEMIpatients with multi-vessel DiseaseMVD Background: In primary percutaneous coronary intervention for STEMI with MVD, complete revascularization has proved to reduce the risk of cardiovascular death and myocardial infarction. However, a strategy of nonculprit-vessel PCI with the goal of complete revascularization still not to be confirmed. Compare with in-hospital staged PCI, out-hospital PCI as a strategy of nonculprit-vessel PCI for STEMI patients with MVD might have be beneficial results.


A total of 1700 subjects with STEMI who met inclusion criteria and do not have any exclusion criterion will be randomized to in-hospital staged PCI group and out-hospital staged PCI group. After successful percutaneous coronary intervention for culprit lesion, all non-culprit vessel with significant lesion defined at least 80% diameter stenosis by visual estimation and accompanied by a QFR measurement of less than or equal to 0.80 will be performed complete revascularization.

  1. Patients randomized to in-hospital staged PCI will have treated during the index procedure (73 days), after revascularization of the culprit lesion, all significant non-culprit coronary lesions.
  2. Patients randomized to out-hospital staged complete revascularization will have treated during the index procedure only the culprit lesion, and they will be hospitalized in 3015 days for complete revascularization of all significant non-culprit coronary lesions.
