The paramount goal of the treatment for acute ST-elevation myocardial infarction (STEMI) is the emergent restoration of blood flow through percutaneous coronary intervention (PCI) of the infarct-related or ‘culprit artery’, generally identified as an occluded vessel from a thrombotic lesion. However, multivessel coronary artery disease (CAD) is frequently present in patients with STEMI and portends a worse prognosis.

The optimal revascularisation strategy for non-culprit coronary lesions in STEMI is unclear.1 The current American College of Cardiology Foundation/American Heart Association and European Society of Cardiology guidelines advise against PCI of non-infarct vessels in the acute setting unless haemodynamic compromise is present, owing to a lack of evidence for its benefit in …
