CalmiGo stress device to improve heart blood vessel health
This study looks at whether a stress-management device (CalmiGo) can improve blood vessel function and heart disease risk in people recovering from recent heart procedures. You would use the device for 12 weeks and complete questionnaires, blood tests, and a heart-vessel test at the start and end.
Rochester, MinnesotaAges 18 years+ - NCT04606732Recruiting

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 - 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 - 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 - NCT02604563Recruiting
Aging, blood changes, and health in older adults
This study examines why some older adults develop changes in their blood cells that may affect their health. Researchers will look for links between these blood changes, aging, and common health problems in older people.
St Louis, MissouriAges 50 years+ - NCT04971720RecruitingPhase 2/Phase 3
Personalized blood pressure timing therapy for some adults
This trial tests whether timing blood pressure medications (based on your natural daily body rhythms) can improve blood pressure control. It’s designed for adults with moderately high blood pressure and focuses on who may benefit from a more precise schedule.
Birmingham, AlabamaAges 18 years+ - NCT05000996Recruiting
Gut microbiome study for people having metabolic surgery
This study looks at your gut bacteria (your “microbiome”) around the time of metabolic surgery. It may help researchers understand how surgery affects gut health and related conditions like diabetes, blood pressure, and cholesterol.
Nashville, TennesseeAges 21–65 - NCT05072483Recruiting
Study of CADASIL’s natural course using blood tests and MRI
This study follows people with CADASIL (a genetic brain blood-vessel condition) to learn how it progresses over time. It uses blood and possibly tissue samples and brain MRI scans to better understand changes in the brain.
Bethesda, MarylandAges 18–100 - NCT05074732Recruiting
Study of forensic mental health admissions after a service move
This study looks at all adult admissions to Ireland’s National Forensic Mental Health Service during a specific time window. It may help improve how the new forensic service at Portrane runs in the future.
DublinAges 18 years+ - NCT05158738Recruiting
Study of inherited heart conditions in children
This trial studies children with inherited (genetic) heart conditions that started before age 16. It may help improve how doctors identify the genetic cause and understand which families are affected.
LondonAges Any age - NCT05174286Recruiting
Phone-based coaching to help prevent colon cancer and heart disease
This study uses community health worker support by phone to help people at higher risk stay on top of recommended screening. It may help reduce colorectal cancer risk and also improve heart health.
New York, New YorkAges 45 years+ - NCT05199454Recruiting
Study how “fat-like” particles affect blood vessel function
This study looks at whether tiny fat-based particles (“adiposomes”) can affect how well your blood vessels work, especially in people with diabetes and higher body weight. You may be asked to do moderate exercise and other study procedures after passing safety checks.
Chicago, IllinoisAges 18–50 - NCT05242315RecruitingPhase 4
Long-acting tacrolimus after liver transplant
This trial studies whether taking an extended-release form of tacrolimus (a medicine to prevent transplant rejection) after a liver transplant works well for people who are followed at the University of Alberta. It may help simplify dosing and monitor safety and effectiveness after transplant.
Edmonton, AlbertaAges 18 years+ - NCT05257629RecruitingPhase 3
Aggressive smoking quit program after heart problems
This trial tests whether a strong quit plan using varenicline (a quit pill) plus nicotine e-cigarettes, along with counseling, helps people stop smoking after a recent heart-related event. It’s aimed at people who want to quit and can safely stay involved for about a year.
New Westminster, British ColumbiaAges 18 years+ - NCT05288790RecruitingPhase 2
Study how gut chemicals and alcohol affect heart risk in HIV
This Phase 2 study looks at how “microbiome metabolites” (chemicals from gut bacteria) and alcohol may affect heart and blood vessel risk in people living with HIV. If you qualify, you may be asked to follow a study plan to see how these factors change health markers related to cardiovascular disease.
Nashville, TennesseeAges 18–89 - NCT05309850Recruiting

Common questions
- Are there clinical trials for cardiovascular diseases?
- Yes. Clin2 currently lists 794 recruiting cardiovascular diseases 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 diseases 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 diseases 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.
