Using PPG to Predict Heart Function in the General Population
Photoplethysmography (PPG) to Predict Ejection Fraction and Other Echographic Data in the General Population
This study is testing if a wristband can help predict heart function in adults by comparing its readings with traditional heart scans.

What this trial studies
This observational study aims to explore the relationship between ejection fraction (EF) measured by echocardiography and signals obtained from Photoplethysmography (PPG) in individuals aged 18 and older. Participants scheduled for an echocardiogram at Tulane University's outpatient cardiology clinic will have their demographics, health habits, and medical history collected. During the echocardiogram, PPG recordings will be taken simultaneously using a Biostrap wristband. The study seeks to develop a predictive model for estimating ventricular ejection fraction based on PPG signals, potentially offering a non-invasive alternative to traditional echocardiography.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older who are scheduled for an echocardiogram at Tulane Medical Center.
Not a fit: Patients under 18, those with cognitive impairments, or individuals unable to wear the Biostrap device will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a non-invasive method for estimating heart function, improving patient access to cardiac assessments.
How similar studies have performed: While the use of PPG in cardiac assessments is emerging, this specific approach to predict ejection fraction is novel and has not been extensively tested in prior studies.
