Plasma Volume Status and Its Association With In-Hospital and Postdischarge Outcomes in Decompensated Heart Failure.

Journal Article (Journal Article)

BACKGROUND: Prior analyses suggest an association between formula-based plasma volume (PV) estimates and outcomes in heart failure (HF). We assessed the association between estimated PV status by the Duarte-ePV and Kaplan Hakim (KH-ePVS) formulas, and in-hospital and postdischarge clinical outcomes, in the ASCEND-HF trial. METHODS AND RESULTS: The KH-ePVS and Duarte-ePV were calculated on admission. We assessed associations with in-hospital worsening HF, 30-day composite cardiovascular mortality or HF rehospitalization and 180-day all-cause mortality. There were 6373 (89.2%), and 6354 (89.0%) patients who had necessary characteristics to calculate KH-ePVS and Duarte-ePV, respectively. There was no association between PV by either formula with in-hospital worsening HF. KH-ePVS showed a weak correlation with N-terminal prohormone BNP, and with measures of decongestion such as body weight change and urine output (r < 0.3 for all). Duarte-ePV was trending toward an association with worse 30-day (adjusted odds ratio 1.07, 95% confidence interval [CI] 1.00-1.15, P = .058), but not 180-day outcomes (adjusted hazard ratio 1.03, 95% CI 0.97-1.09, P = .289). A continuous KH-ePVS of >0 (per 10-unit increase) was associated with improved 30-day outcomes (adjusted odds ratio 0.75, 95% CI 0.62-0.91, P = .004). The continuous KH-ePVS was not associated with 180-day outcomes (adjusted hazard ratio 1.05, 95% CI 0.98-1.12, P = .139). CONCLUSIONS: Baseline PV estimates had a weak association with in-hospital measures of decongestion. The Duarte-ePV trended toward an association with early clinical outcomes in decompensated HF, and may improve risk stratification in HF.
