Could Sodium Supplementation Benefit Patients with Acute Decompensated Heart Failure?

A meta-analysis suggests that sodium supplementation, along with loop diuretics, confers more clinical benefit than loop diuretics alone; however, questions remain, and the practice likely should be limited to subspecialists with advanced heart failure training.

Traditional inpatient management of acute decompensated heart failure emphasizes sodium restriction, but some studies suggest that controlled sodium administration might enhance diuresis and renal perfusion. In a meta-analysis of 16 studies (14 randomized, 2 nonrandomized) with 3500 patients hospitalized with acute decompensated heart failure, researchers compared outcomes with loop diuretics plus sodium administration (hypertonic saline in all but one study) or loop diuretics alone.

Compared with loop diuretics alone, sodium supplementation plus loop diuretics led to significantly more weight loss (mean, 2.5 kg) and shorter hospital length of stay (mean, 2.7 days), as well as substantial improvements in laboratory parameters (i.e., serum cr…
