STEMI patients with mutivessel disease are, after successful primary angioplasty, randomized 1:1 ratio to either in-hospital complete revascularization or after-discharge complete revascularization strategy.~Eligible non-culprit coronary arteries must be >2.0 mm in diameter and at the discretion of the operator suitable for PCI. Only arteries with angiographically stenoses ≥70% or between ≥50% and <70 in proximal segments can be randomized.~Patients in the in-hospital revascularization group will undergo to non-culprit percutaneous coronary intervention (PCI) at least 24 hours after ST-segment elevation myocardial infarction. On the other hand, patients in the after-discharge group will undergo to non-culprit PCI within 4-6 weeks after STEMI.
Patients with STEMI and multivessel disease in whom the culprit lesion has been successfully revascularized during prmimary PCI, will be randomized to in-hospital or after-discharge complete revascularization.~The purpose of this study is to evaluate the impact of these two different strategies in terms of hospital stay.
