What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a new laser-based device (Laser Doppler Vibrometer) to measure how stiff the arteries are in 100 people with high blood pressure. The goal was to see if this painless, non-invasive method works as well as the standard techniques (applanation tonometry and echotracking). The study did not test any treatment, only a new way to measure a key health indicator.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could provide a simpler, non-invasive way to measure artery stiffness, helping doctors better manage high blood pressure.
What could go wrong
This is a small, early-stage validation study, not a treatment trial. The new technique may not prove as accurate or reliable as existing methods.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with grade I-III essential arterial hypertension, recently diagnosed, well controlled or insufficiently equilibrated under stable antihypertensive treatment for their HTA Exclusion Criteria: * Severe pathologies interfering with HTA or not allowing measurement by the techniques of interest, including skin diseases impeding the applanation tonometry * Allergies to ultrasound gel or to adhesive film
