Trial for active or high-risk smoldering myeloma treatments
This Phase 2 study tests a treatment approach for adults with active multiple myeloma (MM) or a high/intermediate-risk “smoldering” MM that hasn’t been treated yet. It may help by trying to control the disease earlier or more effectively, depending on what the trial drug(s) do.

Blood pressure monitoring at local pharmacies
This trial studies using a telemedicine system to check blood pressure in community pharmacies. It may help people with known high blood pressure (treated or untreated) get safer, more convenient monitoring.
Solbiate ArnoAges Any age - NCT03755245Enrolling by invitation
Imaging study using a tracer to measure inflammation in joints and lungs
This trial tests how a radioactive imaging medicine (a tracer called 68Ga-DOTA-Siglec-9) spreads in the body and how well it shows inflammation. It includes both healthy volunteers and people with active rheumatoid arthritis, vasculitis, or pulmonary sarcoidosis to see if the scan matches disease activity.
TurkuAges 18–70 - NCT03683186Enrolling by invitationPhase 3
Long-term study of ralinepag for pulmonary hypertension
This study follows people with pulmonary arterial hypertension (PAH) to see how safe and effective ralinepag is over the long term. It may help your care team understand what to expect from continued treatment and monitoring.
Phoenix, ArizonaAges 18 years+ - NCT03674255Enrolling by invitation
Tests how accurate heart ultrasound is during stress
This study checks how well a heart ultrasound (echocardiography) works when your heart is at rest and under stress. You may benefit by getting closer attention to how the test is done, especially if it’s being used to look for blocked-heart-blood-flow problems.
Ages 18 years+ - NCT03628612Enrolling by invitationPhase 2
Long-term follow-up after CAR T cell treatment
This study checks how people do over the long run after receiving a personalized, genetically modified CAR T cell treatment. It may help researchers understand long-term safety and outcomes, which can improve future care.
Miami, FloridaAges 1 year+ - NCT03527342Enrolling by invitation
Sahlgrenska heart muscle disease study
This study focuses on people with certain “heart muscle” conditions (cardiomyopathies) to better understand them and guide care. If you have one of these specific diagnoses and are an adult, you may be able to take part.
GothenburgAges 18–99 - NCT03395509Enrolling by invitation
Free screening program for diabetes and heart risks
This study looks at how well and how cost-effective a combined health screening is for diabetes and cardiovascular (heart and blood vessel) risks. You may be invited to attend screening around your 67th birthday.
ViborgAges 67–67 - NCT03360227Recruiting
Registry after heart device implantation planning
This is a registry study that records information from people before they get a heart-related device implanted. It may help doctors understand how the team’s tests and planning relate to the procedure and outcomes later on.
DüsseldorfAges 18–80 - NCT03308773Enrolling by invitation
Prevention program for people at risk of type 2 diabetes
This trial looks at a personalized prevention approach for people who are at risk of developing type 2 diabetes. It may help by targeting your specific health factors before diabetes starts.
Ages 18–100 - NCT03300141Enrolling by invitation
Robotic arm training with visual feedback after stroke
This trial tests a robotics-based training program that helps people practice reaching with both the arm and hand, using real-time visual guidance. It may help improve how smoothly and accurately you can reach after stroke.
Chicago, IllinoisAges 18 years+ - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - NCT03244020Enrolling by invitationPhase 4
Aspirin or low-dose blood thinner after bone or leg surgery
This trial compares aspirin versus a low-dose injectable blood thinner (LMWH) to prevent blood clots after certain orthopedic cancer surgeries. It may help lower the risk of dangerous clotting while balancing bleeding and side effects.
Los Angeles, CaliforniaAges 18 years+ - 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.

Common questions
- How many heart & circulation clinical trials are recruiting?
- Clin2 is tracking 10,073 recruiting cardiology studies from the U.S. registry right now, out of 15,588 we cover in this area in total.
- What does “Heart & circulation” cover here?
- Heart disease, blood pressure, and disorders of the blood vessels and circulation. We group each study into heart & circulation based on the conditions it studies, so you can scan the whole therapeutic area at once and drill into a specific condition.
- How do I find a heart & circulation trial near me?
- Use the search to filter heart & circulation studies by location and eligibility. Every Clin2 trial page explains the criteria in plain English and offers a short, optional pre-screen for a fit read — the study team makes the final decision.
