PPG to Predict Ejection Fraction and Other Echographic Data in the General Population

NCT04843371 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 500

Last updated 2026-03-05

No results posted yet for this study

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.

Conditions

  • Valvular Heart Disease
  • Pericardial Disease
  • Cardiomyopathies

Interventions

DIAGNOSTIC_TEST

Photoplethysmography

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.
