Summary

This trial tests whether spironolactone, a pill already used to protect the heart in other patients, can reduce heart failure and heart-related deaths in people on dialysis. Participants take either spironolactone or a placebo daily. The study aims to see if this treatment is both safe and effective for this high-risk group.

What this could mean

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

Active substance
spironolactone 25 mg tablet taken once daily
What this could lead to
If effective, spironolactone could become a standard, low-cost treatment to reduce heart failure and heart-related deaths in people on dialysis.
What could go wrong
The trial is large but still experimental for this population; spironolactone may raise potassium levels, which can be dangerous, and it may not prove beneficial in dialysis patients.
