Abstract

Patients on extracorporeal membrane oxygenation (ECMO) usually have high mortality rate and poor outcome. Age, Creatinine, and Left Ventricular Ejection Fraction (ACEF) score is an easy-calculating score and provides good performance on mortality prediction in patients undergoing cardiac operations or percutaneous coronary intervention, but it has not been applied to patients on ECMO before. In this study, we aimed to use ACEF score obtained within 1 week of ECMO support for in-hospital mortality prediction in patients on ECMO due to severe myocardial failure. This study reviewed the medical records of 306 patients on ECMO at a specialized intensive care unit (CVSICU) in a tertiary-care university hospital between March 2002 and December 2011, and 105 patients on veno-arterial ECMO due to severe myocardial failure were enrolled. Demographic, clinical, and laboratory variables were retrospectively collected as survival predictors. The overall mortality rate was 47.6%. The most frequent condition requiring ICU admission was postcardiotomy cardiogenic shock. Multiple logistic regression analysis indicated that post-ECMO ACEF score, Sequential Organ Failure Assessment score, and troponin I on day 1 of ECMO support were independent risk factors for in-hospital mortality. Using the area under the receiver operating characteristic curve (AUROC), the post-ECMO ACEF score indicated a good discriminative power (AUROC 0.801 ± 0.042). Finally, cumulative survival rates at 6-month follow-up differed significantly (P < 0.001) for an ACEF score ≤ 2.22 versus those with an ACEF score > 2.22. After ECMO treatment due to severe myocardial failure, post-ECMO ACEF score provides an easy-calculating method with a reproducible evaluation tool with excellent prognostic abilities in these patients.
