Photoplethysmography (PPG) to Predict Ejection Fraction and Other Echographic Data in the General Population
Tulane University
Summary
The investigators are aiming to investigate the association between ejection fraction (EF) determined by echocardiography and signals obtained from Photoplethysmography (PPG) in the general population. The investigators are also aiming to investigate the association between blood pressure and signals obtained from PPG in the general population. Finally, the investigators are also aiming to investigate the association between signals obtained from PPG in the general population to cardioechographic findings such as, valvular heart disease, structural heart diseases, cardiomyopathies, pericardial disease etc.
Description
The investigators are proposing a cross-sectional cohort study, where any individual, 18 years old or older, scheduled for an echocardiography at Tulane University's outpatient cardiology clinic can be included. After consenting participants, information on their demographics, personal health habits, medications, and medical history will be collected via reviewing, their electronic medical health records. All participants will undergo an echocardiography as part of their routine medical care by their treating physician. Important echocardiographic findings will be noted such as, EF, valvular h…

Interventions
- Diagnostic TestPhotoplethysmography
Photoplethysmography (PPG) is a non-invasive technique that can detect volumetric changes in the peripheral blood. It only requires skin contact and relies on light absorption. PPG is a good indicator of the cardiovascular dynamics in the human body. PPG has been incorporated into various new smartphones and wearable devices such as, smartwatches and fitness wristbands making it readily available to all consumers. This sensor can record biometrics such as, heart rate, blood pressure, oxygen saturation, etc.
