Optimal timing of staged percutaneous coronary intervention in ST-segment elevation myocardial infarction patients with multivessel disease

Background Studies have shown that staged percutaneous coronary intervention (PCI) for non-culprit lesions is beneficial for prognosis of ST-segment elevation myocardial infarction (STEMI) patients with multivessel disease. However, the optimal timing of staged revascularization is still controversial. This study aimed to find the optimal timing of staged revascularization.
