Trial summary

The objectives of the clinical trial is to validate hemodynamic parameters (Blood pressure and Cardiac Output) generated by an application coupled with an off-the-shelf pulse oximeter. The validation will be done by comparing the generated information to data gathered while performing Stress Echocardiography. Read more about this study

About this study

The objectives of the clinical trial is to validate hemodynamic parameters (Blood pressure and Cardiac Output) generated by an application coupled with an off-the-shelf pulse oximeter. The validation will be done by comparing the generated information to data gathered while performing Stress Echocardiography. The first phase of the study will be done on 10 patients undergoing a Stress Echocardiography test at the cardiology department at Meir Hospital

Read the detailed description

The HeartBeat system combines an FDA/CE approved watch-like Pulse Oximeter for acquiring the data and an android software application that serves as the Hemodynamic calculator. The application performs POST-PROCESSING of the PhotoPlethismoGraphic (PPG) signal (Normally the PPG signal in Pulse Oximeters is used only to compute heart rate and SpO2). The raw data is transferred from the watch oximeter to the smartphone using a standard Bluetooth protocol.

The Post-processing uses wavelet signal processing to estimate and display certain Hemodynamic parameters like Blood Pressure (BP) and Cardiac Output (CO) in a continuous and graphical way on a standard Android device. In addition to the standard heart rate and SpO2, the application displays the measured PPG signal and estimated continues BP and CO.

HeartBeat is the only device that can non-invasively estimate Continuous BP and its Cardiac Output component and the resistance component in a mobile wearable device. Differentiating between these 2 components can play a major role in helping the doctor to understand the effect of cardiovascular medications and Lifestyle interventions.

The trial will compare blood pressure and cardiac output parameters measured during Stress Echocardiography using an echo cardiograph and standard sphygmomanometer to the parameters generated by the application.

Trial goals

  • Feasibility tests for the HeartBeat application as a tool for monitoring BP and CO changes over time
  • Compare BP and CO parameters generated by the applications to the ones measured by standard non-invasive equipment during a Stress Echocardiography
  • Calculate additional parameters such as stroke volume, systematic vascular resistance and cardiac index

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pulse Oximeter CMS50FW (Contec Medical)Device

    The patients will be wearing the pulse oximeter during the test period (20-30 minutes).

    The data from the oximeter will be sent by Bluetooth to the mobile application

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cardiac Output

    Measurement of Cardiac Output at the beginning and the end of the test (30 minutes)

    Measured: Change from Baseline in Cardiac Output at 30 minutes

Secondary outcomes (2)
  1. Blood Pressure

    Measured: Change from Baseline in Systolic and Diastolic blood pressure at 30 minutes

  2. Heart rate

    Measurement of Systolic and Diastolic blood pressure at the beginning and the end of the test

    Measured: Change from Baseline in heart rate at 30 minutes

Questions about this trial

What is this clinical trial studying?

An observational study of High Cardiac Output and Low Cardiac Output, run by HeartBeat Technologies LTD at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 22 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cardiac Output (time frame: Change from Baseline in Cardiac Output at 30 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Feb 2019.
