Key result
Hypertonic saline combined with loop diuretics increases urinary volume and weight loss, and reduces creatinine values in patients with decompensated heart failure complicated by diuretic resistance.
Why the study?
Strict sodium restrictions have been questioned due to lack of proven benefits, while acute HF complicated by diuretic resistance involves excessive renal avidity for sodium that hinders loop diuretics.
Does hypertonic saline associated with loop diuretics improve diuresis and renal function in patients with decompensated heart failure complicated with diuretic resistance?
Does hypertonic saline associated with loop diuretics improve diuresis and renal function in patients with decompensated heart failure complicated with diuretic resistance?
Hypertonic saline combined with loop diuretics is a low-cost, effective strategy to overcome diuretic resistance and improve renal function in patients with decompensated heart failure.
HS may aid diuretic-resistant acute HF; leaves open its net benefit pending prospective trials.
The administration of hypertonic saline (HS) in decompensated heart failure (HF) seems counterintuitive, given the concept that sodium is universally harmful for these patients. However, increasingly, strict sodium restrictions have been questioned due to the lack of proven benefits. On the other hand, we know that in acute HF complicated with diuretic resistance, there is hyperactivation of the renin-angiotensin-aldosterone system (RAAS), resulting in a state of excessive increase in renal avidity for sodium, hindering the action of loop diuretics.

Murad et al. (2023) conducted a review in Decompensated heart failure with diuretic resistance. Hypertonic saline solution vs. Standard therapy or loop diuretics alone was evaluated. Hypertonic saline combined with loop diuretics increases urinary volume and weight loss, and reduces creatinine values in patients with decompensated heart failure complicated by diuretic resistance.
