Recruiting studies near San Diego
- NCT05836987RecruitingPhase 3
Smartwatch-guided blood thinners for intermittent atrial fibrillation
This study tests whether using a smartwatch to monitor your heartbeat can safely guide when to take blood thinners. If you have intermittent atrial fibrillation, you may be able to avoid taking blood thinners when your heart rhythm is normal.
San Diego, CaliforniaAges 22–85 - NCT06989775Recruiting
BoxX-NoAF Trial: Preventing Stroke During Heart Surgery
This trial tests a device to close a small pouch in the heart during planned bypass surgery, to help prevent future strokes. It is for people who have never had an irregular heartbeat and are at higher stroke risk due to age and other factors.
San Diego, CaliforniaAges 65 years+ - NCT06784466Recruiting
New ablation procedure for atrial fibrillation
This study is testing a new type of ablation procedure for atrial fibrillation (an irregular heart rhythm). It uses special energy to create scar tissue in the heart to block faulty electrical signals. If you have AF that isn’t controlled by medication, you may qualify.
San Diego, CaliforniaAges 18–80 - NCT07298473Recruiting
Redo ablation for recurrent atrial fibrillation with Sphere-9 catheter
This trial tests a new catheter and system for people who have had one previous ablation for atrial fibrillation but still have symptoms. It aims to see if a repeat procedure can safely and effectively treat recurrent episodes.
La Jolla, CaliforniaAges 18 years+ - NCT07430956RecruitingPhase 3
Stroke prevention in atrial fibrillation without standard blood thinners
This trial tests a new medication to prevent strokes and blood clots in people with atrial fibrillation (an irregular heartbeat) who cannot safely take standard blood thinners. The drug works by blocking a different clotting factor, which may lower bleeding risks.
La Jolla, CaliforniaAges 18 years+ - NCT07626411RecruitingPhase 3
Blood Thinner Study for Irregular Heartbeat
This study tests a new blood thinner to prevent strokes and blood clots in people with atrial fibrillation (a common heart rhythm problem). You may qualify if you have atrial fibrillation and at least one risk factor for stroke, or if you've never taken a blood thinner before.
La Jolla, CaliforniaAges 18 years+ - NCT07434674Recruiting
Long-Term Atrial Fibrillation After Acute Illness Study
This study is for people who recently had atrial fibrillation (an irregular heartbeat) for the first time while in the hospital or sick. It uses a small implantable heart monitor to see if the irregular heartbeat comes back over the next few years.
La Jolla, CaliforniaAges 18 years+ - NCT07175428RecruitingPhase 2
Safety of a New Blood Thinner in AFib Patients
This study tests the safety of a new blood thinner for people with atrial fibrillation (AFib) who need long-term stroke prevention. If you qualify, the study will compare this medication to standard anticoagulation therapy.
Encinitas, CaliforniaAges 18 years+ - NCT05712200RecruitingPhase 3
Abelacimab for atrial fibrillation when blood thinners aren’t suitable
This Phase 3 study tests whether abelacimab can prevent stroke and other blood-clot problems in people with atrial fibrillation (or atrial flutter) who cannot safely take usual mouth blood thinners. It also looks at safety, especially bleeding risk.

What taking part in a atrial fibrillation study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
