  • Randomised controlled trial
  • pilot

Authors' conclusion

In this pilot trial, the Reprieve System safely produced significantly faster decongestion compared with ODT.

Study context

Population
Hospitalized patients with acute HF96 received randomized treatment
Participants
100 patients
Comparison
Reprieve System vs optimal diuretic therapy
  • Reprieven = 52
  • Optimal diuretic therapy (ODT)n = 44reference
Primary endpoint
24-hour natriuresis (efficacy); composite of dialysis or doubling of creatinine, severe electrolyte abnormalities, hypotension or hypertensive emergency (safety)
Follow-up
24 hours

Primary result

As reported in the abstract

24-hour natriuresis

P < 0.001

Further findings

IV diuretic therapy duration

P = 0.014

Rate of weight loss significantly faster with Reprieve
P = 0.002
Net fluid loss significantly faster with Reprieve
P = 0.03
Net natriuresis significantly faster with Reprieve
P < 0.001

Safety

Primary safety composite (dialysis or doubling of creatinine, severe electrolyte abnormalities, hypotension, hypertensive emergency)

P = 0.42

Change in serum creatinine

P = 0.07
