Mechanical assist devices have emerged as an established therapeutic option for patients with end-stage heart failure. Because preimplant hypoalbuminemia is a known risk factor for adverse outcomes, we hypothesized that change in albumin may be a prognostic indicator in patients with continuous-flow left ventricular assist devices (cfLVADs). This is a retrospective single-center study of patients who underwent cfLVAD implantation (HeartMate II and HeartWare HVAD) at an academic center from 2008 to 2014. After excluding those who died, were transplanted, or hospitalized during the first 3 months post-implant, albumin values were obtained and stratified by an increase or a decrease from pre-implant to 3 months post-implant on 171 (81% male, mean age 57 ± 16 years) patients (139 for the survival analysis and 90 for the hospitalization analysis). Decrease in albumin from pre-implant to 3 months after implant correlated with increased mortality (hazard ratio 2.93, confidence interval 1.57 to 5.44, p <0.01) and reduced time to next hospitalization (hazard ratio 1.70, confidence interval 1.03 to 2.81, p = 0.04). The Kaplan-Meier survival curve estimated a 49.43% 2-year survival rate in those whose albumin decreased versus 83.62% in those whose albumin increased over 3 months (p <0.01). Improved outcomes were seen in patients whose albumin normalized versus patients whose albumin remained normal over 3 months. In conclusion, our study is the first to demonstrate the importance of change in albumin from pre- to postimplant on the prognosis of cfLVAD patients. Future studies are needed to determine whether therapeutic intervention to improve albumin post-implant will prevent hospitalizations and improve outcomes.
