Recruiting studies in California
- NCT05650541Recruiting
Testing a home device to help chronic heart failure
This study tests whether a CardioPulmonary Management (CPM) system device used at home is safe and can improve outcomes for people with chronic heart failure. It may help manage symptoms and reduce complications, especially for higher-risk patients.
Palm Springs, CaliforniaAges 18 years+ - NCT06736574RecruitingPhase 3
Study of omecamtiv mecarbil for chronic heart failure with very weak heart pump
This study tests an investigational medicine (omecamtiv mecarbil) for people with chronic heart failure and very low pumping strength. It looks at whether the drug can help prevent heart failure events or the need for stronger treatments.
Beverly Hills, CaliforniaAges 18–85 - NCT06310031Recruiting
Testing BrioVAD heart pump for severe heart failure
This trial tests a new left-ventricular assist device (LVAD) called BrioVAD for people with advanced heart failure who are not getting enough benefit from medicines. If you qualify, the device is implanted to help your heart pump blood.
Los Angeles, CaliforniaAges 18–100 - NCT07574593Recruiting
Heart Failure Sensor Implant Study
This study tests a small sensor placed in a vein to help monitor and manage heart failure. The sensor tracks fluid buildup in your heart and may help doctors adjust your treatment to keep you feeling better and out of the hospital.
Chula Vista, CaliforniaAges 18 years+ - NCT07219511RecruitingPhase 1
Safety study of VS-041 for heart failure with preserved pumping strength
This trial tests an investigational drug called VS-041 to see if it's safe and helps people with a type of heart failure where the heart pumps well but doesn't relax properly (HFpEF). It may be an option if you are 50 or older and have stable heart failure symptoms.
Huntington Beach, CaliforniaAges 50 years+ - NCT07467668Recruiting
Iron infusion for heart failure patients with low iron
This trial tests whether giving intravenous iron to adults hospitalized with heart failure and low iron levels helps improve their health. You may be eligible if you have heart failure with reduced pumping function and low iron stores.
Pleasanton, CaliforniaAges 18 years+ - NCT07069738Recruiting
New pacemaker vs standard cardiac therapy for heart failure
This study tests a newer type of pacemaker that paces the heart's left bundle branch area, compared to the usual cardiac resynchronization therapy. It is for people with heart failure who need a combined pacemaker-defibrillator (CRT-D) and have a specific heart rhythm pattern (left bundle branch block) with reduced pumping strength.
La Jolla, CaliforniaAges 18 years+ - NCT05677100Recruiting
Aortix device for acute heart failure
This trial is testing a small pump placed in the aorta to help the kidneys remove extra fluid when standard IV diuretics aren't working well enough for severe heart failure. It may help you if you're hospitalized and still very congested (swollen, fluid buildup) despite strong water pills.
Concord, CaliforniaAges 21 years+ - NCT04262830Recruiting
Heart scans to predict future heart failure after chemotherapy
This trial uses detailed heart imaging (a special MRI scan) to see how chemotherapy may have affected your heart and to predict who could develop heart failure later. If you qualify, it may help your care team better monitor your heart health over time.
San Diego, CaliforniaAges 13–39 - NCT04703842RecruitingPhase 1/Phase 2
Study drug effect on heart muscle calcium in advanced heart failure
This trial tests a treatment intended to improve how heart muscle cells handle calcium, which may help heart failure symptoms and heart function. It is mainly for people with advanced heart failure and a low pumping strength of the heart.
San Diego, CaliforniaAges 18–80 - NCT06526988Recruiting
Heart failure medication optimization study for clinicians and patients
This study tests tools to help doctors and patients work together to start or adjust heart failure medicines. You may qualify if your heart's pumping strength is low and you are missing certain recommended medications.
Walnut Creek, CaliforniaAges 18 years+ - NCT05064709Recruiting
Test device for heart failure symptoms in some patients
This study tests whether a heart-related device called CCM can improve symptoms and daily function in people with heart failure and a moderately reduced pumping strength. It may help if you’ve had recent heart-failure-related hospital care or urgent treatment and your heart and overall health fit the study limits.
Concord, CaliforniaAges 18 years+ - NCT05650658Recruiting
Compare two heart pacing options in people with weak heart function
This trial compares two types of “left-side” heart pacing to see which one works better in people with weak heart pumping. It may help guide the best pacing choice for improving heart function and symptoms.
La Jolla, CaliforniaAges 18 years+ - NCT05696652Recruiting
Exercise training study for people with heart failure
This study looks for blood and other markers that can explain how people with heart failure respond to exercise training. It may help researchers better tailor exercise or treatment plans for heart failure in the future.
Stanford, CaliforniaAges 18–89 - NCT05873634Recruiting
Using health records and testing to study heart failure types
This study combines electronic health record data and detailed heart testing to better understand different heart failure types and what treatments may work best for each. It mainly enrolls people with known heart failure, and also some people without heart failure for comparison.
Sacramento, CaliforniaAges 30 years+ - NCT05934487Recruiting
Monitoring device trial for stable heart failure symptoms
This trial tests whether a wearable home monitoring system (myCordella™) can help people with moderate heart failure (NYHA class II or III) by tracking heart pressure and supporting follow-up care. It may help detect changes earlier so clinicians can adjust treatment sooner.
Los Angeles, CaliforniaAges 18 years+ - NCT06424288RecruitingPhase 3
Testing vicadrostat plus empagliflozin for heart failure
This study tests whether adding a new study drug called vicadrostat to the standard heart failure medicine empagliflozin helps people with heart failure. It may be a good option if you have heart failure with preserved pumping function and are not already on a medicine called an MRA.
Chula Vista, CaliforniaAges 18 years+ - NCT06526195Recruiting
A study of CardioMEMS and HeartMate 3 for advanced heart failure
This trial tests if a combination of a tiny lung-artery pressure sensor (CardioMEMS) and a mechanical heart pump (HeartMate 3) is safe and effective for people with advanced heart failure. If you qualify, you'll either get the heart pump plus standard medical therapy, or continue with standard therapy alone and have your pressure monitored remotely.
San Francisco, CaliforniaAges 18 years+ - NCT06699056Recruiting
AI heart monitor study for ejection fraction
This study uses an AI-powered wearable monitor to check how well your heart pumps blood (ejection fraction) from a simple EKG recording. It may help doctors quickly assess heart function without extra tests.
Orange, CaliforniaAges 18 years+ - NCT06008197RecruitingPhase 3
A study of finerenone for hospitalized heart failure patients
This trial tests a medication called finerenone to see if it helps people hospitalized for heart failure live longer and have fewer heart-related problems. It may be an option for those with a certain type of heart failure where the heart's pumping strength is mildly reduced or normal.
West Hills, CaliforniaAges 18 years+ - NCT06895070Recruiting
Heart transplant study using a special preservation machine
This trial tests a special machine that preserves donor hearts for longer periods before transplant. It may help people waiting for a heart transplant who need a heart from a donor that may be older or has some heart risks.
Los Angeles, CaliforniaAges 18 years+ - NCT07037459RecruitingPhase 3
A study of a new drug for heart failure with obesity
This trial tests a medication called maridebart cafraglutide for people with heart failure (where the heart doesn't pump as well as it should) and obesity. The goal is to see if it can help improve symptoms and outcomes.
Orange, CaliforniaAges 18–99 - NCT03142152Recruiting
Mitral valve implant for heart failure with leaky mitral valve
This trial tests whether a device called the Carillon Mitral Contour System can help people with heart failure caused by a mild-to-moderate leaky mitral valve. You’d be compared against a control group, and the goal is to improve heart failure symptoms and outcomes.
San Francisco, CaliforniaAges 18 years+ - NCT07443670Recruiting

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 83 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.
