N2 - Background: Acute heart failure (AHF) exacerbations are a leading cause of hospitalization in the United States. Despite the frequency of AHF hospitalizations, there are inadequate data or practice guidelines on how quickly diuresis should be achieved. Objective: To study the association of 48-h net fluid change and (A) 72-h change in creatinine and (B) 72-h change in dyspnea among patients with acute heart failure. Designs, Settings, and Participants: This is a retrospective, pooled cohort analysis of patients from the DOSE, ROSE, and ATHENA-HF trials. Interventions: The primary exposure was 48-h net fluid status. Main Outcomes and Measures: The co-primary outcomes were 72-h change in creatinine and 72-h change in dyspnea. The secondary outcome was risk of 60-day mortality or rehospitalization. Results: Eight hundred and seven patients were included. The mean 48-h net fluid status was −2.9 L. A nonlinear association was observed with net fluid status and creatinine change, such that creatinine improved with each liter net negative up to 3.5 L (−0.03 mg/dL per liter negative [95% confidence interval [CI]: −0.06 to −0.01) and remained stable beyond 3.5 L (−0.01 [95% CI: −0.02 to 0.001], p =.17). Net fluid loss was associated with a monotonic improvement of dyspnea (1.4-point improvement per liter negative [95% CI: 0.7–2.2], p =.0002). Each liter net negative by 48 h was also associated with 12% decreased odds of 60-day rehospitalization or death (odds ratio: 0.88; 95% CI: 0.82–0.95; p =.002). Conclusion: Aggressive net fluid targets within the first 48 h are associated with effective relief of patient self-reported dyspnea and improved long-term outcomes without adversely affecting renal function.
