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

Table 2 Results of multivariable analyses and the REMEMBER score

Parameter	β Coefficient	OR (95% CI)	p value	Score
Age, years

54–67	1.783	5.95 (2.08–17.06)	0.001	8

The prediction equation is:1/(1 + exp. (3.856–0.220*score)). Hosmer–Lemeshow χ², 6.029 with 8 df; p = 0.644
OR odds ratio, CK-MB creatine kinase-MB
^aLeft main disease was defined as any stenosis ≥ 50% of the left main trunk
^bWorse value within 6 h prior ECMO cannulation
