Summary

This study tests whether an online cognitive behavioral therapy (CBT) program can reduce heart-related anxiety in people who have had a heart attack or unstable angina. 176 participants will be randomly assigned to either the CBT program or a digital lifestyle advice group. The goal is to see if CBT helps people feel less afraid of heart symptoms, improves quality of life, and encourages more physical activity.

What this could mean

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

Active substance: online cognitive behavioral therapy (CBT)
What this could lead to: If it works, this could offer a practical, home-based way to reduce fear and avoidance after a heart attack, helping people feel better and be more active.
What could go wrong: This is a relatively small, early-stage trial testing a behavioral intervention, so results may not apply to everyone. The effect may be modest, and participants must be able to read Swedish.
