Anaemia and Congestion in Heart Failure: Correlations and Prognostic Role.

ABSTRACT: The aim of this study was to evaluate the relationship between anaemia and biomarkers of central/peripheral congestion in heart failure (HF) and the impact on mortality. We retrospectively evaluated 434 acute/chronic HF (AHF/CHF) patients. Anaemia was defined as haemoglobin levels <12 g/dL (women) or <13 g/dL (men). The brain natriuretic peptide (BNP) and hydration index (HI) were measured. The endpoint of the study was all-cause mortality. Anaemia occurred in 59% of patients with AHF and in 35% with CHF (p < 0.001) and showed a significant correlation with the NYHA functional class and renal function. BNP and HI were significantly higher in patients with anaemia than in those without anaemia. Independent predictors of anaemia included BNP, estimated creatinine clearance (eCrCL), and HI. The all-cause mortality rate was 21%, which was significantly higher in patients with anaemia than in those without anaemia (30% vs. 14%, p < 0.001; hazard ratio: 2.6). At multivariate Cox regression analysis, BNP, eCrCL, and HI were independent predictors for mortality (Hazard ratios: 1.0002, 0.97, and 1.05, respectively), while anaemia was not. Anaemia correlates with HF status, functional class, renal function, BNP, and HI. Anaemia was not an independent predictor for mortality, acting as a disease severity marker in congestive patients rather than as a predictor of death.

Project description:AimsWe aim to investigate the additive effect of B-lines on lung ultrasound (LUS) for predicting outcome in patients with heart failure (HF) when combined with conventional assessment of clinical congestion.Methods and resultsThis study prospectively enrolled 117 hospitalized HF patients (61 ± 16 years, 70.1% males) who underwent congestion assessment by the 'wet/dry' status, clinical congestion score (CCS), and B-lines on LUS. The primary endpoint was all-cause mortality or hospitalization for HF during the 180-day follow-up after discharge. The 'Wet', CCS ≥ 3, and B-lines >5, indicators of congestion positive (+), were observed in 83.8%, 76.1%, and 70.1% of the patients on admission, respectively; and the numbers significantly decreased to 41.9%, 41.9%, and 35.9% at discharge, respectively. The agreement between the 'wet/dry' status and B-lines (58.1%) or between CCS and B-lines (56.4%) was moderate at discharge, in terms of both positive and both negative. By incorporating the B-lines with assessment of clinical congestion, the patients at discharge were divided into three phenotypes as clinical congestion (+), clinical congestion (-) with B-lines (+), and clinical congestion (-) with B-lines (-). The Kaplan-Meier analysis showed a better survival in the both (-) group ('wet/dry' with B-lines: Chi-square 10.591, P = 0.005; CCS with B-lines: χ2 6.239, P = 0.031). When the 'wet' patients (n = 49) being taken as the reference, the 'dry' patients with B-lines (+) (n = 21) had an identical risk of the composite endpoint (hazard ratio [HR] adjusted for clinical covariates 1.021, 95% confidence interval [CI] 0.480-2.134, P = 0.974), while the 'dry' patients with B-lines (-) (n = 47) had a lower risk (HR 0.264, 95% CI 0.113-0.617, P = 0.002). When the CCS (+) patients (n = 49) being regarded as the reference, similar results were obtained in the patients with CCS (-) but B-lines (+) (n = 22) (HR 1.348, 95% CI 0.627-2.896, P = 0.444) as well as in those with both CCS (-) and B-lines (-) (n = 46) (HR 0.447, 95% CI 0.202-0.992, P = 0.048).ConclusionsThe combination of B-lines on LUS and conventional assessment helped to identify new phenotypes of congestion that aid in the risk stratification of discharged HF patients. Further investigation is warranted to determine whether this strategy could be adopted as a guide for decongestion therapy.

Project description:AimCongestion is a major determinant of outcomes in acute heart failure. Its assessment is complex, making sufficient decongestive therapy a challenge. Residual congestion is frequent at discharge, increasing the risk of re-hospitalization and death. Mid-regional pro-adrenomedullin mirrors vascular integrity and may therefore be an objective marker to quantify congestion and to guide decongestive therapies in patients with acute heart failure.Methods and resultsObservational, prospective, single-centre study in unselected patients presenting with acute heart failure. This study aimed to assess adrenomedullin's association with congestion and clinical outcomes: in-hospital death, post-discharge mortality and in-hospital worsening heart failure according to RELAX-AHF-2 trial criteria. Pro-adrenomedullin was quantified at baseline and at discharge. Congestion was assessed applying clinical scores. Cox and logistic regression models with adjustment for clinical features were fitted. N = 233, median age 77 years (IQR 67, 83), 148 male (63.5%). Median pro-adrenomedullin 2.0 nmol/L (IQR 1.4, 2.9). Eight patients (3.5%) died in hospital and 100 (44.1%) experienced in-hospital worsening heart failure. After discharge, 60 patients (36.6%) died over a median follow-up of 1.92 years (95% CI: 1.76, 2.46). Pro-adrenomedullin concentrations (logarithmized) were significantly associated with congestion, both at enrolment (β = 0.36 and 0.81 depending on score, each P < 0.05) and at discharge (β = 1.12, P < 0.001). Enrolment of pro-adrenomedullin was associated with in-hospital worsening heart failure [OR 4.23 (95% CI: 1.87, 9.58), P < 0.001], and pro-adrenomedullin at discharge was associated with post-discharge death [HR 3.93 (1.86, 8.67), P < 0.001].ConclusionElevated pro-adrenomedullin is associated with in-hospital worsening heart failure and with death during follow-up in patients with acute heart failure. Further research is needed to validate this finding and to explore the ability of pro-adrenomedullin to guide decongestive treatment.
