Recruiting studies
- NCT04628078Recruiting
Echocardiogram-guided heart procedure registry for atrial fibrillation
This study keeps a real-world record of people with atrial fibrillation who are planning a procedure to close off the heart’s left atrial appendage. Doctors use echocardiography (heart ultrasound) to guide the closure and track outcomes to improve care.
BernAges 18 years+ - NCT04641416Recruiting
Ultrasound test for people with HeartMate 3 blood pumps
This study checks whether a noninvasive ultrasound-based method can help diagnose what’s going on in people with a HeartMate 3 blood pump. It may help detect important pump-related changes while keeping the process safer for certain high-risk situations.
ViennaAges 18–75 - NCT04657783Recruiting
French cohort study of people with type 1 diabetes
This study follows people with type 1 diabetes in France to better understand the condition over time. It may help researchers improve future care, especially for how type 1 diabetes starts and is managed from early diagnosis onward.
ParisAges 6–100 - NCT04669548Recruiting
Accuryn monitoring study for people having heart surgery
This registry collects information from patients who are monitored with the Accuryn system during heart surgery and their ICU stay. It helps researchers learn from the system’s signals to better understand patient care around cardiac procedures.
Los Angeles, CaliforniaAges 18 years+ - NCT04684602RecruitingPhase 1/Phase 2
Study of stem cells for several short- and long-term illnesses
This early-stage study tests whether injections of mesenchymal stem cells can be safe and helpful for certain chronic (long-term) and acute (short-term) conditions. You might be considered if you can consent, are able to return for follow-up visits, and do not have key reasons that would make stem-cell treatment unsafe.
Culver City, CaliforniaAges 18 years+ - NCT04686253Recruiting
Study how a heart opening and its flow link to stroke
This study looks at the detailed flow pattern through a patent foramen ovale (PFO)—a small opening in the heart—and how it may relate to stroke, TIA, or migraine. Doctors use special ultrasound testing with contrast to better understand who is most affected.
Beijing, Beijing MunicipalityAges 16–65 - NCT04691037Recruiting
CT heart scan to guide care for stable chest pain
This trial studies whether a CT heart scan (CCTA) can better guide treatment decisions for people with stable chest pain caused by blocked heart arteries. It may help your care team choose the next best step based on scan results.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04696081Recruiting
Atrial fibrillation treatment in people with active cancer
This trial studies atrial fibrillation (an irregular heartbeat) in adults who have active cancer. It looks at people whose atrial fibrillation started after their cancer diagnosis or returned after cancer diagnosis.
Caen, NormandyAges 18 years+ - NCT04698291Recruiting
Study how genetic differences affect calming immune signals
This study looks at how genetic changes may affect special “calming” immune molecules that help the body resolve inflammation. You may be invited if you already joined the Genes & Health project and had your genome analyzed, and you meet safety and health criteria.
LondonAges 18 years+ - NCT04699279Recruiting
Statin after aortic surgery to protect heart and organs
This trial tests whether taking a cholesterol-lowering medicine (a statin) after certain aortic surgeries can reduce harmful changes in the heart and other organs. You might benefit by lowering the risk of ongoing damage after your acute aortic condition and surgery.
Guangzhou, GuangdongAges 18–85 - NCT04709900Recruiting
Tests for stable chest pain using heart scans and pressure measurements
This trial studies how well different heart tests (imaging the blood flow and measuring blood pressure in the heart) work for people with stable chest pain. It may help guide safer, more accurate evaluation when you are not having a heart attack.
CopenhagenAges Any age - NCT04725617Recruiting
Smoking-quit program for people with HIV and sleep issues
This study tests a wellness-based smoking-cessation program (including the stop-smoking medicine varenicline) for people living with HIV who want to quit. It aims to help you reduce or stop smoking while monitoring safety, sleep, and mental health during the program.
Phoenix, ArizonaAges 18–75 - NCT04743518RecruitingPhase 4
How ulcerative colitis medicines affect blood vessel stiffness
This study looks at how common ulcerative colitis treatments (anti-TNF medicines, vedolizumab, or tofacitinib) change the health of your blood vessels. It may help doctors better understand cardiovascular risk in people with ulcerative colitis.
AmiensAges 18 years+ - NCT04753840Recruiting
Remote arm conditioning and mindfulness for mild high blood pressure
This trial studies whether doing “remote ischemic preconditioning” (repeated brief conditioning of a limb) and mindfulness helps people with mild high blood pressure over the long term. It may help lower blood pressure and improve heart-related health, if you can safely do the required activities.
Zhengzhou, HenanAges 18–80 - NCT04755153Recruiting
Community health program to lower heart disease risk
This trial tests a community-based health intervention in Chicago to help reduce the risk of cardiovascular (heart and blood vessel) disease. It may help people by offering structured support through local clinics or churches.
Chicago, IllinoisAges 18–89 - NCT04779008Recruiting
Remote arm treatment to help blood flow after heart bypass
This trial studies whether a simple, at-home type of treatment using brief arm blood-flow changes can improve blood flow to the heart and outcomes after CABG (heart bypass surgery). It may help some people recover better by protecting the heart around the time of surgery.
Zhengzhou, HenanAges 18–80 - NCT04782232Recruiting
Study of a new blood tube for heart pump patients
This registry study checks whether a new venous blood tube used with a heart pump is safe and practical for people whose right heart is failing and who may need a heart transplant. If you qualify, your care team would monitor how the device works over time.
MunichAges Any age - NCT04791371Recruiting
Study how fitness and insulin resistance relate to diabetes
This study looks at how low physical activity, insulin resistance in small blood vessels, and cardiorespiratory fitness connect to diabetes and blood sugar control. You may be eligible if you are generally sedentary and fit within the weight range, and if you do not have certain heart, lung, nerve, or medication factors.
Aurora, ColoradoAges 30–55 - NCT04827316Recruiting
Use CT heart scans to predict outcomes and guide care
This study looks at people who are having a CT scan of their heart because it’s medically needed. Researchers will use the scan results to better predict future cardiovascular outcomes and improve how care decisions are made.
BernAges 18 years+ - NCT04832568Recruiting
EEG monitoring to predict and prevent postoperative delirium
This study checks brain-wave signals during heart surgery (using EEG monitoring) to understand who is at risk for confusion after surgery. If you qualify, your team will track your thinking after the operation to help reduce or better manage postoperative delirium.

Hormone therapy study on eating, energy, and heart health
This study looks at how cross-sex hormone therapy affects appetite (eating behavior), metabolism (how your body uses food), energy balance, and cardiovascular (heart and blood vessel) health. You may be included if you meet specific health and safety requirements and can follow study procedures.
Leipzig, SaxonyAges 18 years+ - NCT04864171Recruiting

Common questions
- Are there clinical trials for cardiovascular?
- Yes. Clin2 currently lists 1,177 recruiting cardiovascular studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cardiovascular trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cardiovascular trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
