Cardiogenic shock remains a significant cause of mortality in patients with acute coronary syndrome, despite early interventions, such as coronary revascularization. Mechanical circulatory support devices, particularly venoarterial extracorporeal membrane oxygenation (VA-ECMO), are increasingly being utilized to address this issue. Limited randomized controlled trials (RCTs) exist to evaluate the efficacy of VA-ECMO in cardiogenic shock related to acute coronary syndrome.
