Recruiting studies
- NCT04263038RecruitingPhase 4
Watchful waiting versus blood thinners for small lung clots
This trial compares close monitoring (“watch and wait”) versus taking the blood thinner rivaroxaban in people with a small type of lung blood clot. It aims to find out whether low-risk patients can safely avoid or reduce anticoagulation while still staying healthy.
Woluwe-Saint-Lambert, Brussels CapitalAges 18 years+ - NCT04262206RecruitingPhase 4
Testing how statins affect outcomes in adults 75 and older
This trial studies whether cholesterol-lowering medicine (a statin, specifically atorvastatin) improves health and benefits in people age 75 and older in everyday life. It may help doctors understand which older adults benefit most and how to use these medicines safely.
Birmingham, AlabamaAges 75 years+ - NCT04294771Recruiting
Heart problems linked to cancer immunotherapy drugs
This study looks at reports from large health databases to find out if certain cancer drugs (checkpoint inhibitors) cause heart problems. It aims to understand which patients have a higher risk, which may help doctors watch for heart issues in the future.
ParisAges Any age - NCT04216342RecruitingPhase 1
Testing a new breathing-drug ingredient in healthy adults
This early study (Phase 1) tests how safe and tolerable Fx-5A is, and how the body processes it, in healthy volunteers. It’s mainly looking to understand side effects and drug levels rather than treating a disease.
Bethesda, MarylandAges 18–99 - NCT04190758Enrolling by invitation
Early arthritis study for RA, psoriatic arthritis, and psoriasis
This study looks at people with early arthritis related to rheumatoid arthritis, psoriatic arthritis, or psoriasis. Researchers want to understand how these early conditions behave and may help guide better treatment decisions.
GothenburgAges 18–80 - NCT04193475Recruiting
Uses computer learning to improve stress heart ultrasound
This study uses computer technology (“machine learning”) with stress echocardiogram images (a heart ultrasound done during stress) to improve how heart function is measured. If you are able to have a stress echocardiogram, you may be able to help test a better way to interpret the results.
CottinghamAges 20–89 - NCT04185844Recruiting
Chronic kidney health study for Native American adults
This study follows Native American adults with kidney function changes (either moderately reduced kidney filtration or early urine protein). It aims to better understand kidney disease over time and what factors predict progress, which may help improve care for people like you.
Phoenix, ArizonaAges 21–80 - NCT04241328Recruiting
Cardiac surgery registry for patients who used a Medtronic device
This study tracks patients who had cardiac surgery using a specific Medtronic heart-surgery device. It mainly collects real-world data to help understand outcomes, and you may be included if you give consent and are not in another device/drug study that could affect the results.
ViennaAges Any age - NCT04101188Recruiting
Study how extra potassium affects blood vessels
This study looks at how eating more potassium may protect blood vessels in healthy people. You may be eligible if you have normal blood pressure and a normal heart rhythm test, and you do not have certain health conditions.
Newark, DelawareAges 18–45 - NCT04055428RecruitingPhase 2
Testing a hormone supplement to improve heart and metabolic health
This study tests whether adding a natriuretic peptide medicine improves heart health and metabolism in Black adults. It may help with blood pressure and related health markers, but you must meet specific health and safety criteria.
Birmingham, AlabamaAges 18 years+ - NCT04075162Recruiting
Free heart calcium scan program at University Hospitals
This study is looking at people who already received a free coronary artery calcium (CAC) CT scan through a community screening program at University Hospitals. It may help the hospital understand who benefits from offering these no-cost scans.
Cleveland, OhioAges 18–100 - NCT03878706Recruiting
Testing diabetes medicines on heart risk and heart failure
This trial studies how diabetes medicines (GLP-1 and SGLT2, alone or together) affect the heart in people with type 2 diabetes who are at higher cardiovascular risk and have heart failure with preserved pumping function. It may help find safer or more effective ways to reduce heart problems.
Athens, AtticaAges 45–80 - NCT03895541Recruiting
Heart ultrasound stiffness test for elderly diastolic heart failure
This trial tests a new heart ultrasound method to measure stiffness in the heart muscle, which could help doctors diagnose a type of heart failure where the heart is stiff but still squeezes normally. It is for elderly patients with heart failure, and the findings might lead to a simpler and safer way to identify this condition.
ParisAges 18–100 - NCT03927638Enrolling by invitation
Standing versus sitting study for heart and metabolism measures
This trial compares how different body positions (sitting vs standing) affect blood and heart-related measurements in otherwise healthy adults. It may help researchers understand which position is better for metabolic and cardiovascular health.
Montclair, New JerseyAges 18–50 - NCT03983603Recruiting
Plant stanols and asthma symptoms prevention
This trial tests whether eating plant stanols (a natural substance found in some foods) can help prevent asthma symptoms in people with stable allergic asthma. You would need to take a daily chew and avoid certain cholesterol-lowering products during the study.
Maastricht, LimburgAges 18–70 - NCT03813862Recruiting
Study tracking medicines from clinic records
This is an observational study that collects information about what medicines patients receive. It uses data already recorded in participating clinics’ computer health records to better understand medication use over time.
Durham, North CarolinaAges birth+ - NCT03720613Recruiting
Testing medicines to prevent heart events in opioid constipation
This study looks at how well naldemedine (and certain other constipation medicines) lower the risk of major heart problems in people who take opioids for constipation. It compares medicine use patterns in people with opioid-induced constipation to see who has fewer serious heart events.
Wilmington, DelawareAges 18 years+ - NCT03794531Recruiting
Study of health, stress, and lifestyle changes in Puerto Rico
This study looks at how people’s health, day-to-day stress, and living conditions in Puerto Rico change over time. You might help researchers understand what trends are happening and what could be improved.
San JuanAges 30–75 - NCT03790943Recruiting
Health study of heart problems in childhood cancer survivors
This study follows people who had cancer as children to learn about heart-related changes years after treatment. It may help doctors better understand who is at risk and how to monitor the heart in long-term survivors.
Basel, Canton of Basel-CityAges 18 years+ - NCT03777267Recruiting
Test a brain-sensing device for stress, anxiety, or insomnia
This exploratory study tests how a wearable brain-sensing setup (with sensor leads/earbuds) works for people with stress, anxiety, or sleep problems. You may be asked to sit still during sessions and complete brief questionnaires to confirm your symptoms.
