Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This study is testing whether Qidong Yixin Granule can help prevent atrial fibrillation (an irregular heartbeat) from returning after you have ablation surgery to treat it. About 846 people will participate, and each person will have a 50-50 chance of receiving either the actual medication or a placebo (a lookalike with no active ingredient) for 12 months after their ablation procedure. Researchers will check your heart health regularly with heart monitoring tests and ultrasounds to see if the medication helps keep your heartbeat regular.
Atrial fibrillation often comes back even after ablation surgery, and doctors are looking for ways to prevent this recurrence. This medication is being studied because preliminary evidence suggests it might help protect against the rhythm problem returning.

After your ablation surgery, you will receive either the herbal granule or placebo within 48 hours and take one sachet three times daily for 12 months. You will attend follow-up appointments at 1, 3, 6, 9, and 12 months after surgery, during which you'll have heart monitoring tests (EKG and Holter monitor) and heart ultrasounds at certain visits. You will also receive blood thinning medication for at least 3 months after surgery to prevent clots, and researchers will monitor you closely to see if your heart rhythm stays stable.
