Why the study?
The associations of worsening renal function and hemoconcentration with renal outcomes and longitudinal changes in renal function after acute heart failure remain unclear.
Does worsening renal function accompanied by hemoconcentration improve renal outcomes in patients with acute heart failure?
Does worsening renal function accompanied by hemoconcentration improve renal outcomes in patients with acute heart failure?
Worsening renal function accompanied by hemoconcentration during acute heart failure hospitalization is associated with favorable long-term renal outcomes.
Should not yet change AHF decongestion practice; leaves open whether this WRF phenotype is truly renoprotective.
BACKGROUND: Worsening renal function (WRF) in acute heart failure (AHF) has been associated with poor outcomes; however, when accompanied by hemoconcentration, WRF is not necessarily associated with adverse outcomes. The associations of WRF and hemoconcentration with renal outcomes and longitudinal changes in renal function remain unclear. METHODS: , or ≥40% reduction in eGFR within one year after discharge. RESULTS: /year). CONCLUSIONS: Renal function changes after AHF hospitalization were heterogeneous, and WRF accompanied by hemoconcentration was associated with favorable renal outcomes within one year after discharge.
