BACKGROUND: Use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in elderly patients is controversial because of presumed poor outcome. Our primary aim was to determine the influence of advanced age on short- and long-term outcome; the secondary aim was to analyze risk factors for impaired outcome.
METHODS: Between January 2006 and June 2020, 645 patients underwent VA-ECMO implantation in our department. The patients were categorized into four groups:<50, 50-59.9, 60-69.9 and ≥70 years old. Data were retrospectively analyzed for short- and long-term outcome. Risk factors for in-hospital mortality and mortality during follow-up were assessed using multivariate regression analysis.
RESULTS: VA-ECMO support duration was comparable in all age groups (median 3 days). Weaning rates were 60.8%/n = 104 (<50 years), 51.4%/n = 90 (50-59.9 years), 58.8%/n = 107 (60-69.9), and 67.5%/n = 79 (≥70, p = 0.048). Hospital mortality was highest in the patients aged 50-59.9 years (68%/n = 119), but not in the elderly patients (60-69.9, ≥70:62.1%/n = 113, 58,1%/n = 68). At discharge, the cerebral performance category scores were superior in the patients <50 years. Multivariate logistic regression analysis revealed chronic kidney failure requiring hemodialysis, duration of cardiopulmonary resuscitation, and elevated blood lactate levels before VA-ECMO, but not age as predictors of in-hospital mortality. Cox's regression disclosed age as relevant risk factor for death during follow-up. The patients' physical ability was comparable in all age groups.
CONCLUSION: VA-ECMO support should not be declined in patients only because of advanced age. Mortality and neurological status at hospital discharge and during follow-up were comparable in all age groups.
