Heart procedure may beat drugs for AFib patients with heart failure
NCT ID NCT01420393
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether catheter ablation (a procedure to fix irregular heart rhythm) is better than standard rate-control medication for people with both atrial fibrillation and heart failure. Over 400 participants were randomly assigned to either ablation or medication. The main goal was to see which approach reduces deaths and heart failure-related hospital visits. The results could change how doctors treat these two common heart conditions together.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
catheter ablation (a procedure to destroy small areas of heart tissue causing irregular rhythm)
What this could lead to
If successful, this could show that catheter ablation is better than standard medication at reducing deaths and hospital stays for people with both atrial fibrillation and heart failure.
What could go wrong
This is a completed study, but results may not apply to all patients. Catheter ablation carries risks like bleeding, infection, or heart damage, and it may not work for everyone.
