Dynamic Correlation Between Cardiac Filling Pressures And B-Lines In Lung Ultrasound: A Pilot Study

The number of B-lines in lung ultrasound (LUS) is a surrogate of pulmonary congestion, that helps establishing the diagnosis of heart failure (HF)1, and serves as a powerful predictor of worse outcomes in the ambulatory setting2. Moreover, a LUS-guided therapy has the potential to improve prognosis after a HF hospitalization3. Previous studies showed a correlation between the number of B-lines and pulmonary capillary wedge pressure (PCWP) about 0.50 4,5. However, data on the change in the number of B-lines in response to dynamic variation of pulmonary and cardiac pressures are scarce.
