We’re tracking 67 recruiting high blood pressure studies with a site in California — including Phase 3 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT04715568RecruitingPhase 4
Testing how smoke exposure affects heart health
This study looks at whether being exposed to secondhand tobacco smoke at work affects heart and blood vessel health. It may help researchers understand which people are at higher risk and how the body responds to that exposure.
San Francisco, CaliforniaAges 40 years+ - NCT04967989RecruitingPhase 3
Laser eye treatment timing for certain glaucoma or eye pressure
This Phase 3 study tests how best to use a laser treatment (SLT) for people with high eye pressure or mild-to-moderate primary open-angle glaucoma. It aims to find the best way to lower eye pressure and protect vision while comparing treatment approaches.
Laguna Hills, CaliforniaAges 18 years+ - NCT05937685Recruiting
Lower blood pressure after a heart or stroke event
This trial tests ways to help lower blood pressure in people who have had a heart attack or stroke and are at higher risk for more problems. If your blood pressure is high, the program may help reduce risk by getting it under better control.
Los Angeles, CaliforniaAges 35 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 - NCT06129240Recruiting
Study of a new inhaled treprostinil powder for PH-ILD
This study tests a new dry powder inhaled medicine called LIQ861 for people with pulmonary hypertension related to lung scarring (PH-ILD). If you are already taking an inhaled treprostinil treatment but need better control, this trial may help you switch to a potentially easier-to-use version.
Los Angeles, CaliforniaAges 18–80 - NCT06340152Recruiting
Studying maternal health after preeclampsia
This trial follows women who have had preeclampsia to learn more about their health after pregnancy. It collects blood and tissue samples to find markers that could improve future care.
San Diego, CaliforniaAges 18–50 - 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+ - NCT06876233Recruiting
Mobile app to help with blood pressure medication
This trial tests a smartphone app that sends reminders and support to help you take your blood pressure medication regularly. It may be a good fit if you have trouble remembering to take your pills.
Los Angeles, CaliforniaAges 18 years+ - NCT06907147Recruiting
Renal denervation for uncontrolled high blood pressure
This trial tests a procedure called renal denervation to lower blood pressure in people whose medication isn't enough. It uses a special catheter to calm nerves near the kidneys that may be overactive.
Stanford, CaliforniaAges 18–80 - NCT06915792RecruitingPhase 4
Postpartum blood pressure medication and stopping study
This trial compares two blood pressure medicines, nifedipine and labetalol, to see which works better for new mothers with high blood pressure after giving birth. It aims to find the best way to safely stop medicine as blood pressure improves.
Los Angeles, CaliforniaAges 18–64 - NCT07267871Recruiting
Oura Ring Blood Pressure Home Study
This study uses your Oura Ring to see if it can help track your blood pressure. Researchers want to learn how well the ring's sensors can measure changes in your blood pressure over time, which could lead to easier home monitoring.
San Francisco, CaliforniaAges 22 years+ - NCT00932139Recruiting
Electro-acupuncture to help lower high blood pressure
This trial studies whether electro-acupuncture can improve blood pressure in people with mild coronary artery disease or high blood pressure. If it works, it may offer a non-medicine approach to better blood pressure control.
Orange, CaliforniaAges 18–85 - NCT07398391Recruiting
Blood pressure care study in San Diego
This study tests a program to help people manage their blood pressure using video calls and home monitoring. You may join if you have high blood pressure and live in San Diego.
San Diego, CaliforniaAges 21 years+ - NCT07661329RecruitingPhase 3
Comparing a new eye drop to a standard one for glaucoma and high eye pressure
This study tests a new eye drop against an existing one to see which better lowers eye pressure in people with open-angle glaucoma or ocular hypertension. You may be able to join if you have high eye pressure in both eyes that needs treatment and you are at least 18 years old.
Petaluma, CaliforniaAges 18 years+ - NCT07582523Enrolling by invitation
Heart Rhythm Monitoring at Home for High Blood Pressure
This study tests whether wearing a small heart rhythm patch at home can detect irregular heartbeats in people with high blood pressure. It may help catch heart rhythm problems early before they cause symptoms.
San Francisco, CaliforniaAges 60 years+ - NCT06823115Enrolling by invitation
Worldwide study of kidney injury in newborns
This study looks at how common acute kidney injury is in newborns in the intensive care unit. It helps doctors understand which babies are at risk and how to prevent kidney problems.
Palo Alto, CaliforniaAges birth–2 weeks - 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+ - NCT04930289Enrolling by invitation
Lung transplant registry for better donor lung preservation
This study builds a worldwide database to track and improve how donor lungs are preserved before transplant. Your information may help doctors choose and manage donor lungs more effectively.
Stanford, CaliforniaAges Any age - NCT03149341Enrolling by invitation
MRI and computer-heart simulations for heart disease
This study uses MRI scans and computer simulations to learn more about how the heart and blood flow work in people with certain heart or lung conditions. It may help researchers better understand heart problems and improve future care.

What taking part in a high blood pressure 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.

- 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.
