Predicting mortality in patients undergoing VA-ECMO after coronary artery bypass grafting: the REMEMBER score.


ABSTRACT:

Background

Prediction scoring systems for coronary artery bypass grafting (CABG) patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO) have not yet been reported. This study was designed to develop a predictive score for in-hospital mortality for cardiogenic shock patients who received VA-ECMO after isolated CABG.

Methods

Retrospective cohort study of consecutive CABG patients supported with VA-ECMO (n?=?166) at the Beijing Anzhen Hospital between February 2004 and March 2017.

Results

One hundred and six patients (64%) could be weaned from VA-ECMO, and 74 patients (45%) survived to hospital discharge. On the basis of multivariable logistic regression analyses, the pRedicting mortality in patients undergoing veno-arterial Extracorporeal MEMBrane oxygenation after coronary artEry bypass gRafting (REMEMBER) score was created with six pre-ECMO parameters: older age, left main coronary artery disease, inotropic score >?75, CK-MB >?130?IU/L, serum creatinine >?150?umol/L, and platelet count 9/L. Four risk classes, namely class I (REMEMBER score 0-13), class II (14-19), class III (20-25), and class IV (>?25) with their corresponding mortality (13%, 55%, 70%, and 94%, respectively), were identified. The area under the receiver operating characteristic curve 0.85(95% CI 0.79-0.91) for the REMEMBER score was better than those for the SOFA, SAVE, EuroSCORE, and ENCOURAGE scores in this population.

Conclusions

The REMEMBER score might help clinicians at bedside to predict in-hospital mortality for patients receiving VA-ECMO after isolated CABG for refractory cardiogenic shock. Prospective studies are needed to externally validate this scoring system.
