Abstract
This focused update from the Korean Society of Myocardial Infarction provides consensus recommendations for revascularization in acute coronary syndrome (ACS), integrating major trial evidence since 2021 with Korean real-world practice. A multidisciplinary writing committee reviewed randomized trials, meta-analyses, and recent guidelines, and achieved consensus document. Key recommendations are as follows: 1) Cardiogenic shock: prioritize culprit-first revascularization with early reassessment; apply mechanical circulatory support selectively, guided by shock phenotype and escalation criteria rather than routine use; 2) Non-ST segment elevation ACS: use risk-stratified invasive timing with clear triggers for urgent versus early angiography; 3) Access and imaging: adopt radial-first access and broaden intravascular imaging for complex anatomy, ambiguous culprit lesions, and optimization of stent expansion; 4) Non-culprit lesion: favor complete revascularization in ST-segment elevation myocardial infarction (MI) with multivessel disease; select immediate versus staged procedures based on hemodynamics, ischemic burden, renal function, and contrast load. (5) Special scenarios: implement mechanism-based pathways for MI with non-obstructive coronary arteries and spontaneous coronary artery dissection (SCAD), incorporating intracoronary imaging, functional testing, vasospasm provocation, and cardiac magnetic resonance imaging; prefer conservative treatment for SCAD unless ongoing ischemia persists. The document provides concise "do" statements, and a summary of changes from 2021 to facilitate bedside adoption. These recommendations aim to standardize high-value, patient-centered ACS care in Korea, reduce practice variability, and improve outcomes while acknowledging areas requiring further evidence.
