Key result
Hyponatremia affects ~20% of hospitalized HF patients and signals higher morbidity and mortality.
Why the study?
Hyponatraemia is common in heart failure and serves as a surrogate marker of increased morbidity and mortality.
Hyponatraemia is a common complication in heart failure admissions and serves as an important marker for increased morbidity and mortality.
Hyponatraemia flags higher-risk HF admissions for monitoring; leaves open whether correction improves outcomes.
Hyponatraemia is common in heart failure (HF). It is estimated that over 20% of patients admitted to hospital with HF have hyponatraemia. It has also been repeatedly shown to be a surrogate marker of increased morbidity and mortality in this specific population. This review focuses on the pathophysiology of hyponatraemia through the activation of neurohormonal cascades in HF, the clinical implications of sustained hyponatraemia and treatment options in the management of this challenging phenomenon.

Tee et al. (2019) conducted a review in Heart failure with hyponatraemia. Hyponatraemia is present in over 20% of patients admitted to hospital with heart failure and serves as a surrogate marker of increased morbidity and mortality.
