Heart failure & cardiomyopathies
Accuracy of visual estimation of ejection fraction in patients with heart failure using augmented reality glasses
Authors' conclusion
AR glasses could be helpful in measuring LVEF and could be more helpful to those with little visual estimation experience.
Study context
- Population
- Emergency physicians estimating left ventricular ejection fraction (LVEF) from echocardiographic video clips of patients with heart failure (HF)
- Participants
- 22 emergency physicians
- Comparison
- Visual EF estimation with vs without augmented reality (AR) glasses
- Primary endpoint
- ICC of visual EF estimates vs echocardiologists' EF measurements
Methodological detailsprospective, washout period
- Prospective
- Washout period
