Echo and BNP serial assessment in ambulatory heart failure care: Data on loop diuretic use and renal function.

ABSTRACT: We compared the follow-up data on loop diuretic use and renal function, as assessed by serum creatinine levels, and the estimated glomerular filtration rate (eGFR), of two groups of consecutive ambulatory HF patients: 1) the clinically-guided group, in which management was clinically driven based on the institutional protocol of the HF Unit of the Cardiovascular and Thoracic Department of Pisa (standard of care) and 2) the echo and B-type natriuretic peptide (BNP) guided group (patients conforming to the protocol of the Network Labs Ultrasound (NEBULA) in HF Study Group: Pisa, Perugia, Pavia; Verona, Auckland, and Veruno), in which therapy was delivered according to the serial assessment of BNP and echocardiography. Patients whose follow-up was based on standard of care had a significant higher prevalence of worsening renal function, that was likely related to higher diuretic dosages, whilst, a better management of renal function was observed in the echo-BNP-guided group. The data is related to "Echo and natriuretic peptide guided therapy improves outcome and reduces worsening renal function in systolic heart failure: An observational study of 1137 outpatients" (A.

Project description:Rationale & objectiveHeart failure treatment relies on loop diuretics to induce natriuresis and decongestion, but the therapy is often limited by diuretic resistance. We explored the association of renin-angiotensin-aldosterone system (RAAS) activation with diuretic response.Study designObservational cohort.Setting & populationEuvolemic ambulatory adults with chronic heart failure were administered torsemide in a monitored environment.PredictorsPlasma total renin, active renin, angiotensinogen, and aldosterone levels. Urine total renin and angiotensinogen levels.OutcomesSodium output per doubling of diuretic dose and fractional excretion of sodium per doubling of diuretic dose.Analytical approachRobust linear regression models estimated the associations of each RAAS intermediate with outcomes.ResultsThe analysis included 56 participants, and the median age was 65 years; 50% were women, and 41% were Black. The median home diuretic dose was 80-mg furosemide equivalents. In unadjusted and multivariable-adjusted models, higher levels of RAAS measures were generally associated with lower diuretic efficiency. Higher plasma total renin remained significantly associated with lower sodium output per doubling of diuretic dose (β = -0.41 [-0.76, -0.059] per SD change) with adjustment; higher plasma total and active renin were significantly associated with lower fractional excretion of sodium per doubling of diuretic dose (β = -0.48 [-0.83, -0.14] and β = -0.51 [-0.95, -0.08], respectively) in adjusted models. Stratification by RAAS inhibitor use did not substantially alter these associations.LimitationsSmall sample size; highly selected participants; associations may not be causal.ConclusionsAmong multiple measures of RAAS activation, higher plasma total and active renin levels were consistently associated with lower diuretic response. These findings highlight the potential drivers of diuretic resistance and underscore the need for high-quality trials of decongestive therapy enhanced by RAAS blockade.

Project description:BACKGROUND:Despite the fact that loop diuretics are a landmark in acute heart failure (AHF) treatment, few trials exist that evaluate whether the duration and timing of their administration and drug amount affect outcome. In this study, we sought to evaluate different loop diuretic infusion doses in relation to outcome and to diuretic response (DR), which was serially measured during hospitalization. METHODS:This is a post-hoc analysis of a DIUR-HF trial. We divided our sample on the basis of intravenous diuretic dose during hospitalization. Patients taking less than 125 mg of intravenous furosemide (median value) were included in the low dose group (LD), patients with a diuretic amount above this threshold were inserted in the high dose group (HD). The DR formula was defined as weight loss/40 mg daily of furosemide and it was measured during the first 24 h, 72 h, and over the whole infusion period. Outcome was considered as death due to cardiovascular causes or heart failure hospitalization. RESULTS:One hundred and twenty-one AHF patients with reduced ejection fractions (EF) were evaluated. The cardiovascular (CV) death/heart failure (HF) re-hospitalization rate was significantly higher in the HD group compared to the LD group (75% vs. 22%; p < 0.001). Both low DR, measured during the entire infusion period (HR 3.25 (CI: 1.92-5.50); p < 0.001) and the intravenous diuretic HD (HR 5.43 [CI: 2.82-10.45]; p < 0.001) were related to outcome occurrence. Multivariable analysis showed that DR (HR 3.01 (1.36-6.65); p = 0.006), intravenous diuretic HD (HR 2.83 (1.24-6.42); p=0.01) and worsening renal function (WRF) (HR 2.21 (1.14-4.28); p = 0.01) were related to poor prognosis. CONCLUSIONS:HD intravenous loop diuretic administration is associated with poor prognosis and less DR. Low DR measured during the whole intravenous administration better predicts outcome compared to DR measured in the early phases.
