Background: We performed a single-center retrospective analysis to determine whether preoperative serum albumin levels were associated with postoperative adverse events and short- and long-term survival in patients who underwent continuous-flow left ventricular assist device (CF-LVAD) implantation. Methods: From November 2003 through March 2016, 526 patients underwent CF-LVAD implantation. Patients whose preoperative serum albumin level was normal (≥3.5 g/dL) were compared to patients with preoperative hypoalbuminemia (<3.5 g/dL), which was further categorized as moderate (2.5-3.5 g/dL) or severe (<2.5 g/dL). These groups were compared regarding preoperative demographics, incidence of postoperative complications, and long-term survival. Results: Patients with hypoalbuminemia had higher serum levels of liver enzymes (P < 0.05) and total bilirubin (P < 0.001) and significantly lower platelet counts (P = 0.02) and prealbumin levels (P < 0.001) than patients with normal preoperative albumin levels. Survival in patients with moderate and severe preoperative hypoalbuminemia was significantly decreased compared with patients with normal preoperative serum albumin levels (P < 0.001). Preoperative hypoalbuminemia was also associated with higher incidences of postoperative infection, gastrointestinal bleeding, neurological dysfunction, and acute kidney injury (P ≤ 0.01 for all) but did not affect the success of bridge to transplantation or survival after transplantation. Conclusions: Our data demonstrated that there is a significant association of preoperative low serum albumin levels with postoperative adverse outcomes and lower survival rates. This highlights the importance of a patient's preoperative nutritional status on postoperative outcomes after CF-LVAD implantation.
