NCT05873387

Brief Summary

The major goal of the study is to determine whether phonocardiography (using the Eko DUO stethoscope which can capture a three lead ECG reading) can present features that relate to the presence of PH diagnosed by echocardiography or right heart catheterization (RHC), and therefore have a potential to assist the provider to suspect PH.

Outcome Measures

Primary Outcomes (2)

  • Build a database of matched ECG/PCG recordings labeled against RHCs and echocardiograms

    Create a training/validation dataset composed of ECG/PCG recordings by enrolling at least 2200 subjects undergoing echocardiography and at least 220 subjects who have undergone right heart catheterization (RHC)

    Up to 2 years to complete database

  • Develop and clinically test a deep learning algorithm that can detect PH and stratify its severity

    Deliver an algorithm that detects PH with a sensitivity and specificity of ≥ 0.7

    Up to 3 years to complete algorithm development

Study Arms (2)

Sampling MethodNon-Probability Sample
Study Population

Patients will be enrolled from Miriam and Rhode Island Hospital and Cardiovascular Institute outpatient locations where echocardiography or right heart catheterizations are performed. Approximately 40% of the patients enrolled will have a confirmed diagnosis of pulmonary hypertension.

You may not qualify if:

  • Patients undergoing limited echocardiography
  • Intubated patients
