NCT05641675

Brief Summary

A proprietary machine-learning algorithm has been developed to model continuous pulmonary artery pressure (PAP), a physiologic marker of cardiopulmonary function. The algorithm was developed from PAP recordings obtained during invasive right heart catheterization. The study will evaluate whether this algorithm can perform as well when embedded into a non-invasive wearable device that records EKG, heart sounds, and thoracic impedance has yet to be established.

Outcome Measures

Primary Outcomes (1)

  • Major Outcome

    The primary outcome of this study is to determine if a machine-learning algorithm with data from a wearable device can reproduce simultaneous PAP measurement obtained during right heart catheterization.

    the Swan-Ganz catheter obtains the pulmonary artery pressures for a minimum of 5 minutes

Study Arms (1)

right heart catheterization cohort

The study investigators will screen up to 50 Veterans undergoing right heart catheterization for clinical indications with the intention to consent up to 20 Veterans. Veterans will be screened by study investigators. Veterans who decline to consent and vulnerable populations (pregnant, incapacitated, incarcerated) will be excluded from the study.

Diagnostic Test: right heart catheterization

Interventions

Connect to a heart monitor to record heart rate, blood pressure and blood oxygen levels Place sterile sheets on chest and neck (or groin area) Clean the skin over the neck or groin Give local anaesthetic to numb the area (this may sting a little when it is given) Gently pass a catheter into a vein to the heart Record pressure readings from the heart chambers and lungs Give medication, depending on heart's pressure readings Remove the catheter and apply pressure where it was inserted

Study Population

The study investigators will screen up to 50 Veterans undergoing right heart catheterization for clinical indications with the intention to consent up to 20 Veterans. Veterans will be screened by study investigators. Veterans who decline to consent and vulnerable populations (pregnant, incapacitated, incarcerated) will be excluded from the study.

You may qualify if:

  • Written informed consent and authorization to use and disclose health information.
  • years of age or older.
  • Diagnosis of HF for \>3 months, with preserved or reduced left ventricular ejection fraction (LVEF).
  • Female subjects of childbearing age with a negative urine or serum pregnancy test at the time of the right heart cauterization procedure and trial.

You may not qualify if:

  • Active infection.
  • Unable to tolerate a right heart catheterization (RHC), in the investigator's opinion.
  • Implantation of cardiac resynchronization therapy (CRT)\<3 months before enrollment.
  • Enrolled in concurrent studies that may confound the results of this study.
  • Clinical condition that would not allow them to complete the study, in the investigator's opinion.
