Subgroup analysis for male sex
After adjusting and comparing both groups concerning gender, the baseline parameter did not show significant differences (Table 5). There was a significantly higher rate of acute kidney injury (AKI) leading to dialysis in the ECMO+Impella® group, compared with the ECMO group (71% vs. 25%, p= 0.03). Also, the ECMO+Impella® group received significantly more red blood units (26 vs. 10, p=0.01) and platelets (0 vs. 3, p= 0.01). Moreover, ICU-stay was significantly longer in the ECMO+Impella® group (21 vs. 1 day, p = 0.03). Overall mortality was significantly lower in the ECMO+Impella® group (29% vs. 85%, p= 0.01).
