About this study

Official title: Comparison of Cuff-Less Wrist Wearable to Cuff Based Commercial Available Blood Pressure Measuring Devices in Health Volunteers With Normal or High Blood Pressure

(1) To compare cuff-less wrist wearable radial artery blood pressure measurements utilizing ViTrack(developed by Dynocardia) to the cuff based commercially available blood pressure device, in healthy volunteers with normal or high blood pressure.

Read the detailed description

(1) The ViTrack is strapped over the radial artery at the wrist. The ViTrack blood pressure cuff will be utilized to obtain blood pressure(BP) readings in the volunteers with normal or high blood pressure. The readings from the ViTrack will be compared with the readings of a cuff-based, commercially available BP measuring device placed on the same arm.

Being tested
ViTrack, Oscillometric BP Device, Auscultatory cuff
Keywords

What participants receive

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

  • ViTrackDevice

    ViTrack is a continuous non-invasive wearable blood pressure cuff.

  • Oscillometric BP DeviceDevice

    Oscillometric blood pressure measurement is the standard of care for measuring blood pressure in outpatient / home settings.

  • Auscultatory cuffDevice

    The auscultatory method is the gold standard for clinical blood pressure measurement. A brachial cuff is mounted and a trained healthcare provider uses a sphygmomanometer and listens for the Korotkoff sounds using a stethoscope to measure blood pressure.

Study groupRoleWhat they receive
Experimental-ArmFor the same subject, 1. ViTrack wrist cuff is applied on one of the wrist 2. Standard Oscillometric cuff is applied to the brachial artery / wrist of the same arm 3. Auscultatory cuff is applied to the brachial artery of the same arm
Receives: Device: ViTrack; Device: Oscillometric BP Device; Device: Auscultatory cuff

What is being measured

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

  1. Comparison of Diastolic Blood Pressure

    3 sets readings compared across blood pressure (mmHg)

    Measured: up to 30 minutes

  2. Comparison of Systolic Blood Pressure

    3 sets readings compared across blood pressure (mmHg)

    Measured: up to 30 minutes

Secondary outcomes (1)
  1. Skin Irritation

    Examining for local skin irritation

    Measured: Up to 72 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertension and Healthy, run by Dynocardia, Inc at 1 site in United States.

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: looking for participants now, as of the sponsor's last update on 5 Sep 2025. 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 United States. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Mohan Thanikachalam, MD (+1 (617) 639 - 5569, admin@dynocardia.care), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Comparison of Diastolic Blood Pressure (time frame: up to 30 minutes). 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?
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 5 Sep 2025.
