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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a noninvasive procedure called remote ischemic preconditioning can improve blood vessel function in people with suspected heart failure with preserved ejection fraction. Participants will have a blood pressure cuff inflated around their arm in cycles, while a control group receives no treatment. The researchers will measure various vascular parameters before, right after, and up to 24 hours later. This is a small, early study with 48 participants, so it is mainly about gathering knowledge on whether this approach might work.

What this could mean

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

Active substance
remote ischemic preconditioning (a procedure using a blood pressure cuff to temporarily restrict blood flow)
What this could lead to
If it works, this could point toward a simple, noninvasive way to improve blood vessel health in heart failure patients.
What could go wrong
This is a very small, early-phase study with only 48 participants. It only looks at short-term effects (up to 24 hours), so any benefits may not last or lead to a real treatment.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 48 people

The number the study aims to enrol. It can still change while the study runs.

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

Inclusion Criteria: 1. Signs and symptoms of Heart Failure (Clinical suspicion of Heart Failure) 2. Sedentary men and women (structured exercise \<2 x 30 min/week). 3. Age ≥40 years 4.
