Dialysis patients: could a workout or arm squeeze shield your heart?

NCT ID NCT06856512

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether light exercise or a technique called remote ischaemic preconditioning (rIPC) — using a blood pressure cuff to briefly restrict blood flow to the arm — could protect the heart during dialysis. 33 adults on hemodialysis took part in three sessions: one with exercise, one with rIPC, and one with neither. Researchers measured heart function and blood markers to see if these simple additions reduce heart strain.

What this could mean

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

Active substance
exercise and remote ischaemic preconditioning (rIPC)
What this could lead to
If it works, this could point toward a simple way to reduce heart strain during dialysis, improving heart health for kidney patients.
What could go wrong
This is a small, early-stage study with only 33 participants, so results may not apply to everyone. The interventions are short-term and may not provide lasting benefits.
