Abstract
In recent years, practice and guidelines for patients with ST-elevation myocardial infarction (STEMI) have evolved from a 'culprit-only approach' to complete revascularisation; however, several issues remain, particularly regarding assessment of non-culprit lesions and timing of their revascularisation. Complete revascularisation should be performed in patients presenting with STEMI; however, available studies often present contradictory results regarding the optimal timing of non-culprit lesion percutaneous coronary intervention (PCI). The aim of this review is to provide a practical approach for the assessment of patients presenting with STEMI and multivessel coronary artery disease by analysing randomised trials, meta-analyses and our clinical experience. We recommend multivessel revascularisation at the time of primary PCI for simple cases, while we suggest deferring treatment of complex lesions; the optimal timing of staged PCI should be individualised according to clinical judgement.
