Correlation between the Venous Excess Ultrasound (VExUS) score and right atrial pressure: a pilot prospective observational study
Authors' conclusion
These results suggest a strong correlation between VExUS and RAP in a diverse patient population
Study context
- Population
- Patients undergoing right heart catheterization at Denver Health Medical Center
- Exposure
- VExUS score vs inferior vena cava (IVC) diameter for right atrial pressure (RAP)
- Outcome
- Correlation of VExUS with right atrial pressure (RAP)
Methodological detailspilot, blinded ultrasonographers
- Pilot
- Blinded ultrasonographers
Main finding
As reported in the abstract
Association between RAP and VExUS grade
Significant positive association between RAP and VExUS grade (adjusted for age, sex, common comorbidities), P < 0.001
R2 = .68
Observational data: associations, not effects.
