Key result
Persistent blood volume expansion is linked to better 1-year event-free survival in chronic left-sided HF.
Why the study?
The relationship between the severity of right ventricular dysfunction and blood volume expansion on clinical outcomes in chronic left-sided heart failure had not been assessed.
Is persistent blood volume expansion associated with improved 1-year event-free survival in patients with chronic left-sided heart failure and right ventricular dysfunction?
Observational
Is persistent blood volume expansion associated with improved 1-year event-free survival in patients with chronic left-sided heart failure and right ventricular dysfunction?
In patients with chronic left-sided heart failure and right ventricular dysfunction, persistent blood volume expansion may act as an adaptive response associated with improved 1-year event-free survival.
This analysis provides a novel assessment of the relationship between the severity of right ventricular dysfunction (RVD) and blood volume expansion (BVE) on clinical outcomes in patients with chronic left-sided heart failure. Findings demonstrate that despite the high prevalence of moderate or greater RVD, persistent BVE was associated with better 1-year event-free survival relative to normal BV. Hypothesis-generating, this suggests that BVE may provide an adaptive response compensating in part for the impact of RVD in chronic HF.

Miller et al. (2025) conducted an observational in chronic left-sided heart failure. Persistent blood volume expansion (BVE) vs. Normal blood volume (BV) was evaluated on 1-year event-free survival. Persistent blood volume expansion was associated with better 1-year event-free survival relative to normal blood volume in patients with chronic left-sided heart failure.
