Outcomes

Primary Outcome Measures

Death within 30 days (composite endpoint)
The primary endpoint will rank patients from worst to most favourable outcome during the trial. It will be a hierarchical composite of events as described by Felker in 2010 (PMID 20841546).
Hospitalization for heart failure within 30 days (composite endpoint)
The primary endpoint will rank patients from worst to most favourable outcome during the trial. It will be a hierarchical composite of events as described by Felker in 2010 (PMID 20841546).
Changes in N-terminal pro b-type natriuretic peptide (NtProBNP) between randomization and D30 (composite endpoint)
The primary endpoint will rank patients from worst to most favourable outcome during the trial. It will be a hierarchical composite of events as described by Felker in 2010 (PMID 20841546).

Secondary Outcome Measures

Cardiovascular death
Within the combined outcome of CV death or hospitalization for heart failure. Outcomes will be adjudicated blinded from randomization arm
Ultrasound pulmonary congestion defined ≥3 B-lines on two intercostal spaces bilaterally (8-point method) and systemic congestion defined as an inferior vena cava diameter 21 mm or greater and/or a low variation during the respiratory cycle
Circulating levels of natriuretic peptides (NtProBNP)
Changes in natriuretic peptides (NtProBNP)
Ultrasound congestion defined as in B / and clinical congestion evaluated according to the EVEREST and ASCEND scores

5. Study Description

Brief Summary
AMBUSH study is a multicenter randomized, controlled, open-label clinical trial (PROBE (Prospective Randomized Open Blinded End-point) type). The main objective of AMBUSH study is to assess the effect of therapeutic management guided by pulmonary ultrasound and the assessment of the inferior vena cava in patients with heart failure seen in an ambulatory (outpatient) setting on a mixed clinical-biological endpoint (including variations of natriuretic peptides - NtProBNP) at 30 days.
Detailed Description
Secondary objectives are: A. To assess the effect of therapeutic management guided by pulmonary ultrasound and inferior vena cava assessment on the risk of cardiovascular death and hospitalization for heart failure at 30 days. B. Describe the proportion of ultrasound congestion (pulmonary and inferior vena cava data) in patients free from clinical congestion at baseline in the intervention group and in all patients at D30 visit. C. Evaluate the association of ultrasound congestion (pulmonary and inferior vena cava assessment) with serum concentrations of natriuretic peptides at baseline and D30 visit. D. Evaluate the association of variations in ultrasound congestion (pulmonary and evaluation of the inferior vena cava) and variations in natriuretic peptides between baseline and D30 visit. E. Compare the proportion of ultrasound and clinical congestion in patients in the intervention group and in the control group at baseline and on D30 visit.
