Summary

This study is investigating how often dangerous heart rhythm problems occur in people receiving hemodialysis for end-stage kidney disease. Researchers will implant a small device under the skin to continuously monitor heart rhythm for 18 months in 70 patients, half of whom have diabetes. They will also use continuous glucose monitors to check blood sugar levels and collect blood samples monthly. The goal is to see if diabetes, low blood sugar, or dialysis-related factors are linked to arrhythmias, which could help improve care 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: Implantable loop recorder and continuous glucose monitor
What this could lead to: If successful, this could identify which dialysis patients are at higher risk for dangerous heart rhythm problems, potentially guiding closer monitoring or preventive care.
What could go wrong: This is an observational study, so it cannot prove cause and effect. The small size (70 patients) and specific population may limit how broadly the findings apply.
