Hyponatremia is an independent predictor of poor prognosis in heart failure, with management options including fluid restriction and vaptans.
May warrant closer sodium monitoring in HF; leaves open whether correction improves outcomes.
Hyponatremia is a significant and independent predictor of outcomes including rehospitalization and mortality in patients with both acute decompensated heart failure (HF) and chronic HF. Even modest degrees of hyponatremia are associated with a poorer prognosis. Treatment options include fluid restriction and the vaptan class (“aquaretics”) in select patients.
