Abstract Background The persistent challenge of high mortality rates in acute myocardial infarction–induced cardiogenic shock endures notwithstanding advancements in the diagnosis and treatment of this disease over the past two decades. While recent studies present conflicting evidence on the efficacy of veno-arterial extracorporeal membrane oxygenation (VA ECMO), observational research supports the benefits of early VA ECMO initiation. However, the current lack of robust support from randomized clinical trials for VA ECMO use in this context highlights the ongoing uncertainty surrounding its effectiveness. Case summary A 52-year-old male with sudden, intense chest pain was diagnosed with cardiogenic shock due to non–ST-elevation acute myocardial infarction at a local hospital. Initial treatment included aspirin, clopidogrel, and noradrenaline. Upon transfer to our hospital, the patient’s condition deteriorated, leading to acute respiratory distress and severe hypotension. Prior to emergent percutaneous coronary intervention, peripheral VA ECMO was initiated. Coronary angiography revealed left main coronary artery occlusion, and a successful intervention was performed. Post-intervention, the patient’s haemodynamic parameters significantly improved, and after 7 days, ECMO was successfully discontinued. The patient was discharged in stable condition after 25 days, with favourable outcomes persisting at the 30-day mark. Continuous monitoring is planned during outpatient follow-up. Discussion The clinical case illustrates a successful treatment outcome achieved through teamwork by the heart team, supporting the efficacy of the VA ECMO pre–percutaneous coronary intervention approach. The careful selection of appropriate candidates and strategic initiation of VA ECMO may play a role in enhancing outcomes for individuals experiencing acute myocardial infarction complicated by challenging cardiogenic shock.
