Abstract
Background
Worsening heart failure (WHF) is defined as persistent or worsening symptoms of heart failure that require an escalation in intravenous therapy or initiation of mechanical and ventilatory support during hospitalization. We assessed a simplified version of WHF called diuretic failure (DF), defined as an escalation of loop diuretic dosing after 48 h, and assessed its effects on mortality and rehospitalizations at 60-days.
Methods
We conducted a multicenter retrospective study between December 1, 2017 and January 1, 2020. We identified 1389 patients of which 6.4% experienced DF.
Results
There was a significant relationship between DF and cumulative rates of 60-day mortality and 60-day rehospitalizations (p = 0.0002 and p = 0.0214). After multivariate adjustment, DF was associated with longer hospital stay (p < 0.0001), increased rate of 60-day mortality (p = 0.026), 60-day rehospitalizations (p = 0.036), and a composite outcome of 60-day mortality and 60-day cardiac rehospitalizations (p = 0.018).
Conclusions
DF has a strong relationship with adverse heart failure outcomes suggesting it is a simple yet robust prognostic indicator which can be used in real time to identify high-risk patients during hospitalization and beyond.
