Lung Ultrasound in Acute Heart Failure: Prevalence of Pulmonary Congestion and Short- and Long-Term Outcomes.

ABSTRACT:

Objectives

This study sought to assess the prevalence, changes in, and prognostic importance of B-lines, a pulmonary congestion measure by using a simplified lung ultrasonography (LUS) method in acute heart failure (AHF).

Background

Pulmonary congestion is an important finding in AHF, but conventional methods for its detection are insensitive.

Methods

In a 2-site, prospective, observational study, 4-zone LUS was performed early during hospitalization for AHF (LUS1) and at discharge (LUS2). B-lines were quantified off-line, blinded to clinical findings and outcomes, by a core laboratory.

Results

Among 349 patients (median, 75 years of age; 59% men; mean ejection fraction 39%), the sum of B-lines in 4 zones ranged from 0 to 18 (LUS1). The risk of an adverse in-ho
