What is a key management goal for HF patients with hyponatremia?

• A. Treat underlying HF with guideline-directed medical therapy and fluid restriction if appropriate; address neurohormonal activation.
• B. Immediately increase fluid intake.
• C. Hyponatremia treatment entails sodium supplementation only.
• D. Ignore hyponatremia and continue current therapy.

Answer: (A)

Hyponatremia in heart failure stems from neurohormonal activation that promotes excess water retention, reducing the effective arterial blood volume. The best management goal is to treat the underlying heart failure with guideline-directed medical therapy to blunt this neurohormonal drive, and to use fluid restriction if appropriate to limit free water intake. By improving cardiac function and reducing ADH-driven water retention, sodium levels can improve over time. Simply increasing fluid intake or sodium supplementation won’t fix the underlying imbalance and ignoring the hyponatremia misses an important prognostic signal.
