Pragmatic Urinary Sodium-Based Algorithm in Acute Heart Failure - PUSH-AHF

Contribution To Literature:

The PUSH-AHF trial showed that natriuresis-guided therapy improves natriuresis; however, this strategy did not improve clinical outcomes.

Description:

The goal of the trial was to evaluate natriuresis-guided therapy compared with usual care among patients with acute decompensated heart failure.

Study Design

  • Randomized
  • Parallel
  • Open-label

Patients with acute decompensated heart failure were randomized to natriuresis-guided therapy (n = 150) vs. usual care (n = 160). In the natriuresis-guided group, urine sodium was evaluated at 2, 6, 12, 18, 24, and 36 hours. Diuretic treatment was intensified if urine sodium level was low (<70 mmol/L). 

  • Total number of enrollees: 310
  • Duration of follow-up: 180 days
  • Mean patient age: 74 years
  • Percentage female: 45%

Inclusion criteria:

  • Patients admitted with acute decompensated heart failure
  • Planned treatment with a loop diuretic

Principal Findings:

The co-primary outcome, natriuresis at 24 hours, was 409 mmol in the natriuresis-guided group vs. 345 mmol in the usual care group (p = 0.0061).

The co-primary outcome of all-cause mortality or heart failure hospitalization at 180 days was 31% in the natriuresis-guided group vs. 31% in the usual care group (p = 0.70).

Interpretation:

Among patients with acute decompensated heart failure, natriuresis-guided therapy improves natriuresis compared with usual care. Natriuresis-guided therapy did not improve clinical outcomes. This strategy deserves further study.
