Introduction:
The risk of unfavourable outcomes after an acute heart failure (AHF) episode remains high. Effective decongestion, reflected by haemoconcentration (HC), may guide therapy. Optimal timing of HC remains unspecified.
Methods:
We analysed the AHF registry to evaluate the prognostic differences of various timing of HC. Subjects were divided into 3 groups by time of reaching HC.
Results:
The groups differed in terms of 1-year occurrence of a composite of the mortality and AHF hospitalization (26% vs. 46% vs. 40%, early vs. late vs. no HC, p = 0.016).
Conclusions:
Patients reaching HC earlier seem to present the best prognosis regarding the analysed composite endpoint.
