Catheter ablation vs. drugs for atrial fibrillation with heart failure
Part of Heart & circulation clinical trials.
This study compares two treatments for people with atrial fibrillation (an irregular heartbeat) and heart failure with preserved ejection fraction (a type of heart failure where the pumping function is still normal). You would receive either catheter ablation (a procedure to correct the heart's rhythm) or anti-arrhythmia drugs, to see which works better to improve your symptoms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have atrial fibrillation that comes and goes or is persistent, and it has been documented in the last 3 months.
- You have tried or cannot take standard heart rhythm medications, or you prefer not to use them.
- You have been diagnosed with heart failure with preserved ejection fraction (your heart's pumping strength is normal, but it still causes symptoms).
- You have heart failure symptoms that limit your daily activities (New York Heart Association class II, III, or IV).

Other trials that look related to this one.
This trial tests a new procedure called pulsed field ablation for people who have both persistent atrial fibrillation and a type of heart failure (HFpEF). It aims to see if this ablation safely helps control the heart rhythm.
This trial tests two different catheters that use pulsed field energy to treat atrial fibrillation (a heart rhythm problem). It aims to find which one works better for people who need blood thinners but have a high risk of bleeding.
This trial compares a procedure called ablation (using cold, heat, or electric pulses to fix irregular heartbeats) with standard medications to see which better treats heart failure in people who also have atrial fibrillation. It may help if your heart's pumping ability is reduced and you still have symptoms despite medications.
This study tests whether a catheter ablation procedure can help people with atrial fibrillation and a kind of heart failure where the heart pumps normally but doesn't relax properly (HFpEF). It looks at whether the procedure can improve symptoms and heart function.
This trial compares two ways to treat atrial fibrillation in people with heart failure where the heart's pumping strength is still normal. You'll either get a procedure called ablation to restore normal rhythm or medication to control your heart rate. The goal is to see which approach works better for people like you.
This study compares different treatments—pacing therapy, medications, and catheter ablation—for people who have both atrial fibrillation and heart failure. It aims to find the best way to improve your heart function and quality of life.
