Strategies and Timing of Complete Revascularization in STEMI Patients with Multivessel Coronary Artery Disease

Le résumé fourni par la source

Multivessel coronary artery disease is observed in a substantial proportion of patients presenting with ST-segment elevation myocardial infarction (STEMI) and identifies a higher-risk phenotype characterized by larger atherosclerotic burden, recurrent ischemic events, and greater need for subsequent revascularization. Over the past decade, randomized evidence has progressively shifted the interventional paradigm from culprit-lesion-only primary percutaneous coronary intervention (PCI) toward complete revascularization in hemodynamically stable STEMI patients with suitable non-culprit lesions. Nevertheless, several clinically relevant questions remain unresolved, including the optimal criteria for selecting non-culprit lesions, the relative value of angiography, coronary physiology, and intracoronary imaging, the timing of complete revascularization, and the management of patients presenting with cardiogenic shock. Angiography-guided complete revascularization has the strongest evidence base, while physiology-guided approaches may reduce unnecessary PCI but have not demonstrated superiority over angiography-guided strategies in direct randomized comparisons. Intracoronary imaging offers unique information on plaque vulnerability and PCI optimization, although dedicated outcome trials in STEMI remain limited. The timing of complete revascularization has also evolved, with contemporary trials supporting early treatment in selected stable patients but not establishing a universal immediate strategy. This review summarizes current evidence, unresolved controversies, and emerging directions regarding strategies and timing of complete revascularization in STEMI patients with multivessel disease.
