Association of VA-ECMO support and long-term quality of life after post-cardiotomy cardiogenic shock: experience from a prospective cohort
Impact of VA-ECMO on Long-Term Quality of Life in Post-Cardiotomy Cardiogenic Shock
Overview
This prospective study assessed long-term quality of life (QoL) in patients with post-cardiotomy cardiogenic shock (PC-CS) treated with or without veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Results showed that while overall QoL was satisfactory more than one year after ICU discharge, VA-ECMO was independently associated with significantly lower physical health scores, indicating persistent physical limitations.
Background
Post-cardiotomy cardiogenic shock affects 2–6% of cardiac surgery patients and is associated with high morbidity and mortality. VA-ECMO is a life-saving circulatory support used in severe cases but carries risks of complications that may impact long-term QoL. Previous evidence on post-ECMO QoL is limited by small sample sizes and lack of comparable controls. This study aimed to evaluate QoL at least 12 months after ICU discharge using the SF-36 questionnaire in a large cohort of PC-CS survivors with and without VA-ECMO.

Key Findings
Among 291 survivors of moderate to severe PC-CS, 55 had VA-ECMO and 176 did not; median age was 67 years.
Overall, survivors achieved satisfactory physical and mental SF-36 scores (78 and 80 respectively) more than one year post-ICU.
VA-ECMO was independently associated with a significant reduction in physical SF-36 scores by 11.1 points after adjusting for confounders.
Physical health domains most affected by VA-ECMO included role limitation due to physical problems and bodily pain.
Mental health scores were slightly lower in VA-ECMO patients but the difference was not statistically significant.
Physical health was more profoundly impaired than mental health in this population, consistent with prior studies.
Clinical Implications
Clinicians should recognize that PC-CS survivors treated with VA-ECMO face persistent physical limitations impacting their quality of life long-term. Structured multidisciplinary post-ICU follow-up including targeted physical rehabilitation programs is essential to address these deficits. Early screening and management of ECMO-related complications, such as cannulation site issues, may facilitate better functional recovery.
Conclusion
Survivors of post-cardiotomy cardiogenic shock generally achieve good long-term quality of life, but those requiring VA-ECMO experience significant and persistent physical impairments. These findings underscore the need for dedicated rehabilitation and follow-up strategies to improve outcomes in this high-risk group.
