New app aims to ease anxiety for heart device patients
NCT ID NCT06667505
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study is testing a new online resource called Choice-ICD for people who have or are getting an implantable cardioverter defibrillator (ICD). The app includes videos, quizzes, and a forum to help patients and their families understand the device and live better with it. About 64 patients in Belfast and Glasgow will use the app for 3 months, and researchers will check if it is easy to use and helps reduce anxiety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Choice-ICD eHealth app (behavioural intervention)
- What this could lead to
- If it works, this could give ICD patients a simple online tool to feel more informed and less anxious about their device.
- What could go wrong
- This is a small, early feasibility study with only 64 patients using the app. It may not show clear benefits or be easy for everyone to use.
