This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This trial is testing whether treating atrial fibrillation (irregular heartbeat) early with a procedure called ablation can help prevent serious complications like strokes and heart failure, especially in people who have multiple other health conditions. The procedure uses a special catheter to safely restore a normal heart rhythm. Researchers believe this approach may work better than taking medications alone to control the irregular heartbeat.

Many people with irregular heartbeat still suffer strokes and heart complications even when taking blood thinners and other medications. This trial exists to see whether fixing the heart rhythm problem earlier with a procedure—rather than waiting and using only medications—can better protect patients, especially those dealing with multiple other health challenges.

Do you qualify?

You likely qualify if…

you have been diagnosed with atrial fibrillation within the last 5 years, confirmed by an electrocardiogram (ECG)
you have a high burden of other health conditions, measured by a score of 4 or higher
you are at least 18 years old
your doctor believes you are a safe candidate for ablation using approved catheter systems
you are willing to provide informed consent and participate in the study

You likely don't qualify if…

you have a serious illness that is expected to limit your life to less than one year
you have had a stroke within the 3 months before enrollment
you have had ablation or surgery for irregular heartbeat before
you have heart valve disease that requires specific treatment
you are pregnant, breastfeeding, or have active drug or alcohol abuse

What participation looks like

If you are assigned to the early ablation group, you will receive a heart rhythm procedure designed to restore normal rhythm. If you are in the usual care group, you will continue your current heart medications and treatments. Both groups will be followed over time with regular visits and tests to track serious heart events like stroke, heart failure hospitalization, and death. The study aims to enroll 2,312 patients and will continue until enough major health events have occurred to answer the research question.
