About this study

The aim of this study is to verify the long-term accuracy of blood pressure and heart rate measurements by Samsung smartwatches between two consecutive calibrations compared to a standard digital tonometer used in clinical practice and for home measurement of these vital parameters.

Read the detailed description

Recently, smartwatches can measure a wide range of biological signals, including heart rate and blood pressure. The short-term reliability of blood pressure measurements after the required calibration has been studied, but long-term reliability is still a question. The aim of the project is to experimentally evaluate the reliability of long-term blood pressure measurement with a Samsung smart watch between two consecutive calibrations over a period of 28 days in comparison with a digital tonometer (Omron) approved as a medical device. Volunteers will measure blood pressure and heart rate manually twice a day from a smartwatch and a digital tonometer simultaneously. The agreement of the measurements of both devices will be evaluated.

What participants receive

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

  • Resting measurement of blood pressure and heart rateOther

    Simultaneous blood pressure and heart rate measurement every morning and evening during the duration of the experiment (28 days).

Study groups in NCT05401435
Study groupRoleWhat they receive
Blood pressure and heart rate measurementExperimentalResting blood pressure and heart rate measurement regularly one value in the morning and evening for 28 days. The volunteer measures the parameters simultaneously on both devices (smartwatch and digital tonometer). In total, each participant will undergo this measurement 56 times.
Receives: Other: Resting measurement of blood pressure and heart rate

What is being measured

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

  1. Change in long-term similarity of blood pressure measurements from two devices between two consecutive calibrations

    The long-term agreement of systolic and diastolic blood pressure measurements of both monitoring devices between two consecutive smartwatch calibrations will be evaluated. This means that we evaluate the changes in the similarity of measured blood pressures over a period of 28 days.

    Measured: 28 days

  2. Change in long-term similarity of heart rate measurements from two devices

    The long-term agreement of heart rate measurements of both monitoring devices will be evaluated. This means that we evaluate the changes in the similarity of measured heart rates over a period of 28 days.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A study testing Resting measurement of blood pressure and heart rate in people with Blood Pressure and Heart Rate, run by Czech Technical University in Prague at 1 site in Czechia.

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 1 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 2 Jun 2022. 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 Czechia. 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?

Contact Barbora Nezpevakova, Bc. (+420728096216, nezpebar@fbmi.cvut.cz), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in long-term similarity of blood pressure measurements from two devices between two consecutive calibrations (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05401435, which also lists 1 linked publication.

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 2 Jun 2022.
