Pulmonary congestion is expressed in the form of B-lines detected by lung ultrasound (LUS), which has proven to be a potent prognostic predictor of hospitalization and mortality in HF. However, it is still unknown if a treatment strategy guided by LUS in HF patients may improve outcomes.

The objective of our study is to analyze whether a treatment guided by LUS in patients with HF reduces the combined endpoint of readmission for HF worsening or death in a 6-month follow-up.

LUS-HF (NCT02959372 at is a randomized, single center, simple blind clinical trial that enrolls patients older than 18 years who have been hospitalized for HF. The exclusion criteria are life expectancy less than 6 months or severe lung disease. Eligible patients are randomized into either the "LUS group" or the "control group". The follow-up consists of visits in the HF clinic at periods of 15 days, 1, 3, and 6 months after discharge. Both groups are examined with LUS, but the result of the test is only provided to the treating physician in the "LUS group".

Clinical characteristics of the first 52 patients included are summarized in the table. The primary endpoint occurred in the 42.3% of the "control group" versus 19.2% of the "LUS group" (log-rank test 0.077, figure).

According to the preliminary results of the LUS-HF trial, LUS guided treatment may reduce readmissions in HF patients.
