Heart failure & cardiomyopathies
Association between B-lines on lung ultrasound, invasive haemodynamics, and prognosis in acute heart failure patients
Authors' conclusion
A clear pivot point was associated with increased B-lines count in PCWP at 19 and 25 mmHg for preserved and reduced EF, respectively. Moreover, the increased B-line count above the defined cut-off used to quantify residual congestion was associated with significantly worse outcomes.
Study context
- Population
- Hospitalised patients with acute HF undergoing right heart catheterisation before discharge, stratified by preserved and reduced ejection fraction (EF)
- Participants
- 116 patients
- Exposure
- Residual congestion vs no residual congestion at discharge
- Outcome
- Correlation of lung ultrasound (LUS) B-line count with PCWP, by preserved and reduced EF
Main finding
As reported in the abstract
B-line count vs PCWP
Pulmonary capillary wedge pressure (PCWP) threshold for increase in B-lines, preserved EF
19 mmHg
PCWP threshold for increase in B-lines, reduced EF
25 mmHg
Observational data: associations, not effects.
