Chronic systolic heart failure (HF) with acute decompensation can result in cardiogenic shock (CS) requiring short-term mechanical circulatory support. We sought to identify predictors of survival for acute decompensated HF (ADHF) patients requiring veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Patients >18 years old treated at our institution with VA-ECMO from 2009 to 2018 for ADHF with CS were studied. Demographic, hemodynamic, and echocardiographic data were collected. The primary outcome was survival to discharge. Fifty-two patients received VA-ECMO for ADHF with CS; 24 (46.2%) survived. Seventeen (32.7%) had suffered cardiac arrest, and 37 (71.2%) were mechanically ventilated. Mean lactate was 4.33 ± 3.45 mmol/L, and patients were receiving 2.7 ± 1.2 vasopressor/inotropic infusions at ECMO initiation; these did not differ significantly between survivors and nonsurvivors. Pre-ECMO cardiac index was 1.84 ± 0.56L/min/m2 and 1.94 ± 0.63L/min/m2 in survivors and nonsurvivors, respectively (p = 0.57). In multivariable analysis, only diabetes mellitus (DM; OR, 13.25; CI, 1.42–123.40; p = 0.02) and mineralocorticoid receptor antagonist use (OR, 0.12; CI, 0.02–0.78; p = 0.03) were independent predictors of mortality. Nineteen (79.2%) survivors required durable ventricular assist device. Among ADHF patients receiving VA-ECMO, DM is a powerful predictor of outcomes while markers of clinical acuity including hemodynamics, vasopressor/inotrope use, and lactate are not. The vast majority of survivors required durable left-ventricular assist devices.
