2026 Focus Update of the 2021 Korean Society of Myocardial Infarction Expert Consensus Document on Revascularization for Acute Coronary Syndromes

Key Result

The updated consensus recommends culprit-first revascularization in cardiogenic shock, selective mechanical circulatory support, radial-first access, and intravascular imaging for complex lesions in ACS.

Key Points

This update aims to revise and improve guidelines for revascularization in patients experiencing acute coronary syndromes.
The document synthesizes recent evidence and expert opinions on revascularization strategies.
Recommendations were developed through comprehensive literature review and consensus among experts.
Specific patient populations and intervention types were considered to enhance clinical approaches.
Revised guidelines emphasize timely revascularization to improve survival and reduce complications.
New interventions are suggested based on emerging evidence and technological advancements.
The consensus document aims to standardize care practices for acute coronary syndromes.

Structured PICO

Population

Patients with acute coronary syndromes (ACS), including acute myocardial infarction (AMI) complicated by cardiogenic shock, non-ST-segment elevation ACS (NSTE-ACS), ST-segment elevation myocardial infarction (STEMI) with multivessel disease, and myocardial infarction with non-obstructive coronary arteries (MINOCA) in Korea.

Intervention

Revascularization strategies including percutaneous coronary intervention (PCI), mechanical circulatory support (MCS) such as Impella, IABP, and VA-ECMO, and intravascular imaging (IVUS, OCT).

This focused update provides contemporary, evidence-based consensus recommendations for the revascularization of acute coronary syndromes tailored to Korean clinical practice.

Limitations

The document provides practical guidance based on expert consensus rather than definitive, guideline-level recommendations.
Further randomized trials are needed to clarify optimal strategies in specific subgroups, such as AMI-related cardiogenic shock requiring mechanical circulatory support.

Abstract

Lee et al. (Thu,) conducted a review in Acute Coronary Syndrome. Updated revascularization strategies vs. Previous 2021 consensus guidelines was evaluated. The updated consensus recommends culprit-first revascularization in cardiogenic shock, selective mechanical circulatory support, radial-first access, and intravascular imaging for complex lesions in ACS.
