A significant proportion of patients with ST-segment elevation myocardial infarction (STEMI) have multivessel coronary artery disease (CAD). Following successful culprit lesion percutaneous coronary intervention (PCI) for STEMI, the question of whether to routinely revascularize non-culprit lesions or manage them conservatively with optimal medical therapy (OMT) alone is a common dilemma facing clinicians. METHODS: COMPLETE is a prospective, randomized, international, multicenter, parallel group, open-label trial with blinded evaluation of outcomes. Following successful PCI (contemporary drug eluting stents recommended) of the culprit lesion for STEMI, a total of 4041 patients from 140 centers in 31 countries were randomized to receive either complete revascularization, consisting of staged PCI of all suitable non-culprit lesions plus optimal medical therapy (OMT), or to culprit lesion-only PCI, consisting of OMT alone. OMT comprises evidence-based therapy for STEMI, including and dual antiplatelet therapy with ticagrelor, HTN and lipid management. All coronary angiograms in the trial are being evaluated in a central angiographic core lab to assess quality and completeness of revascularization. The co-primary outcomes are (1): the composite of CV death or new non-fatal MI and (2 the composite of CV death, new non-fatal MI or ischemia-driven revascularization at a median follow-up of 3 years. CONCLUSIONS: The COMPLETE trial is an international multicenter randomized trial that will help determine whether complete revascularization involving staged PCI of non-culprit lesions improves outcomes in patients with STEMI and multivessel CAD.
