Lung ultrasound in outpatients with heart failure: the wet‐to‐dry HF study

Abstract:

Aims In ambulatory patients with chronic heart failure (HF), congestion and decongestion assessment may be challenging. The aim of this study is to assess the value of lung ultrasound (LUS) in outpatients with HF in characterizing decompensation and recompensation, and in outcomes prediction. Methods and results Heart failure outpatients attended to establish HF decompensation were included. LUS was blindly performed at baseline (LUS1) and at clinical recompensation (LUS2). B‐lines were counted in eight scanned areas. Diagnosis of no HF decompensation vs. right‐sided, left‐sided, or global HF decompensation, and patients' management were performed by physicians blinded to LUS1. Outcome was the composite of all‐cause death or HF‐related hospitalization. Two hundred and thirty‐three suspicions of HF decompensation were included in 187 patients (71.4 ± 11.3 years, 66.8% men).
