Immediate multivessel revascularization after myocardial infarction: change of strategy?

Abstract

Abstract Multivessel coronary artery disease (MVD) is a frequently encountered condition in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) of the culprit vessel. Several studies have demonstrated the benefit of complete coronary revascularization compared with the treatment of the culprit lesion only in patients with STEMI. Based on this evidence, the current European guidelines recommend that in haemodynamically stable patients with STEMI and MVD, routine complete revascularization should be achieved either during the same procedure in concomitance with the treatment of the culprit lesion (immediate multivessel PCI) or with a subsequent intervention within 45 days from the index PCI of the culprit lesion (deferred multivessel PCI). However, the guidelines do not express a preference for immediate vs. delayed multivessel PCI. Therefore, the optimal timing of the treatment of non-culprit lesions in patients with STEMI and haemodynamic stability is still debated and has been evaluated in recent studies that showed the non-inferiority of immediate vs. delayed multivessel PCI. The article discusses the results and clinical implications of these studies on the timing of complete revascularization of non-culprit lesions in haemodynamically stable patients with STEMI.
