Heart failure clinical trials in California
We’re tracking 87 recruiting heart failure studies with a site in California — including Phase 2 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT06812533Recruiting
Testing a new approach for heart failure with weak pump
This study tests a new device or procedure to help people with heart failure and a weak heart pump. If you have a low ejection fraction and are on standard medications, you may be able to join.
Los Angeles, CaliforniaAges 18 years+ - NCT06793371RecruitingPhase 2
Study of CK-4021586 for heart failure with preserved ejection fraction
This trial tests an investigational drug called CK-4021586 for people with heart failure with preserved ejection fraction (HFpEF). It aims to see if the drug is safe and well-tolerated. You may qualify if you are 40 to 85, have heart failure symptoms, and have a heart that pumps well but shows signs of strain.
Imperial, CaliforniaAges 40–85 - NCT06779552Recruiting
Study of CardioMEMS System for Heart Failure Patients
This study is looking at how well the CardioMEMS heart monitor works for people with heart failure. The device is already implanted and tracks pressure in your lung artery to help your doctor manage your condition and potentially prevent hospital visits.
Pleasanton, CaliforniaAges 18 years+ - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+ - NCT06039176Recruiting
Learning from the HeartMate 3 device
This study looks at information from the HeartMate 3 LVAD device to learn more about how it works and what it can tell us about the future. It may help people with advanced heart failure who need this specific device.
San Francisco, CaliforniaAges 18–100 - NCT05791227Enrolling by invitation
Testing AI tool that measures heart wall thickness on ultrasound
This study tests an artificial-intelligence (AI) software tool that measures heart muscle thickness from routine heart ultrasound images. It focuses on whether the AI measurements are safe and accurate when used by the clinic’s echocardiography team.
Los Angeles, CaliforniaAges 18–100 - NCT05685303Recruiting
Testing a treatment for heart failure symptoms with normal pumping ability
This study is looking at a new treatment for people with heart failure where the heart’s pumping strength is not reduced much (HFpEF or HFmrEF), but pressure inside the heart is high during exercise. It may help relieve symptoms in people who still feel unwell during normal activity despite stable standard treatment.
Santa Barbara, CaliforniaAges 40 years+ - NCT05427370Recruiting
Compare bypass or stent treatment in weak heart patients
This study compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stent procedure (PCI)—in people with a weak pumping heart. It looks at which approach works best when the heart muscle is not pumping well and there are multiple blocked heart arteries.
Los Angeles, CaliforniaAges 18 years+ - NCT05180773RecruitingPhase 4
Bromocriptine for new postpartum heart weakness
This trial studies whether bromocriptine improves health outcomes in people recently diagnosed with peripartum cardiomyopathy (a weakened heart during late pregnancy or soon after delivery). You may be asked about timing after childbirth, heart strength tests, and whether you plan to keep breastfeeding.
Orange, CaliforniaAges 18 years+ - NCT04592445Recruiting
Nerve ablation for right-sided symptoms in HFpEF heart failure
This trial tests a procedure to “turn off” the right greater splanchnic nerve to improve symptoms in people with HFpEF (heart failure with preserved pumping function). If successful, it may reduce shortness of breath and fluid congestion in daily life.
San Francisco, CaliforniaAges 40 years+ - NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Los Angeles, CaliforniaAges birth–20 years - NCT03876223Recruiting
Testing imaging to study heart symptoms without blocked arteries
This trial studies people who have heart-related symptoms but do not have clear blocked heart arteries, using special heart imaging. It may help researchers better understand early forms of heart weakness (with preserved pumping function) and improve how these conditions are diagnosed.
Los Angeles, CaliforniaAges 18 years+ - NCT01790152Recruiting
Dexrazoxane study to monitor heart damage in cancer survivors
This study tests dexrazoxane (DRZ) to see how it affects blood and heart-related “biomarkers,” or measurable signs of heart damage, after cancer treatment. It mainly targets survivors who may be at risk for cardiomyopathy (heart muscle weakness) or related heart failure.
Palo Alto, CaliforniaAges Any age - NCT00271180Recruiting
Tracks long-term performance of Medtronic heart devices
This study follows how well certain Medtronic heart devices work over the long term. You may be included if you have a qualifying Medtronic implant and the research team can reliably get your implant and follow-up information.
Bakersfield, CaliforniaAges Any age - NCT06939751Recruiting
Testing microRNA levels to personalize heart transplant care
This trial is studying whether a blood test that measures small molecules called microRNAs can help doctors personalize the medicines used to prevent rejection after a heart transplant. If you qualify, you would help researchers learn how to better match immunosuppression to each patient's needs.
Los Angeles, CaliforniaAges 18–99

What taking part in a heart failure 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.

Common questions
- Are there heart failure clinical trials in California?
- Yes. We're currently tracking 87 recruiting heart failure studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a heart failure study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a heart failure trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New heart failure studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
