Hyponatremia is a well-established marker of adverse outcomes in chronic heart failure (HF) but not well studied in patients with left ventricular assist device (LVAD). This is a retrospective study, single center study of HM3 [Abbott, USA] LVAD implants. We divided our population based on their sodium prior to LVAD implantation - hyponatremia if <135 mEq/L and normal sodium if 135-145 mEq/L. We compared postoperative and long-term outcomes. A total of 195 patients were included, preimplant hyponatremia was present in 40% with a sodium of 132.1 ± 2.1 vs 137.8 ± 1.9 mEq/L in the normal sodium group. No differences were observed in the postoperative or long-term outcomes. Preimplant hyponatremia was not associated with mortality or HF admissions, likely due to adequate left ventricular unloading and resolution of the mechanisms that lead to hyponatremia. These results suggest that optimization of mild hyponatremia may not be critical and should not delay LVAD placement.
