What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

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.

Summary

This study tests whether using a lung water monitor to tailor fluid intake can prevent acute kidney injury in elderly patients with kidney disease who are undergoing coronary angiography. 320 participants will receive hydration rates adjusted based on their lung water levels. The goal is to see if this personalized approach reduces kidney damage compared to standard care.

What this could mean

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

Active substance
tailored hydration guided by a remote dielectric sensing system
What this could lead to
If successful, this could provide a simple, personalized way to prevent kidney damage after heart procedures in older adults with kidney problems.
What could go wrong
This is an early-stage study with no prior results, and the approach may not reduce kidney injury or could cause fluid overload. The results may not apply to all patients.
