Low-dose colchicine to lower risk in leg artery disease
This trial tests whether low-dose colchicine can reduce “residual” risk—future heart and blood-vessel problems—in people with peripheral artery disease (PAD). It targets PAD symptoms and complications like poor blood flow in the legs, even after certain procedures.
New Haven, ConnecticutAges 18 years+ - NCT04777994RecruitingPhase 1
Drug ABBV-CLS-484 for advanced cancers that lack options
This Phase 1 trial tests ABBV-CLS-484 in people with advanced or metastatic tumors when standard treatments have not worked or aren’t available. Because it’s an early study, the main goal is to find a safe dose and see how the cancer responds in different cancer types.
Tucson, ArizonaAges 18 years+ - NCT04769206RecruitingPhase 1/Phase 2
Boost nerve signaling to improve blood vessel function
This study tests a treatment aimed at increasing “rest-and-digest” nerve activity to improve how blood vessels work, especially in people with vascular oxidative stress. It is designed for African American adults and looks at whether the intervention can improve blood vessel-related health markers.
Nashville, TennesseeAges 18–60 - NCT04753593Recruiting
Using Leftover Surgery Tissue for Research
This study collects tiny pieces of tissue that would normally be thrown away during heart or bone surgery. Researchers will use these samples to better understand how tissues work and develop better treatments. Your participation involves letting doctors keep and study a small amount of tissue removed during your scheduled surgery.
AmiensAges 18 years+ - NCT04750876Recruiting
Psychological and physical therapy follow-up after leg amputation
This trial tests whether adding both psychological support and physical therapy check-ins before and after leg amputation improves recovery and rehab planning. It may help patients feel better and regain function during the transition to rehabilitation care.
La Roche-sur-YonAges 18 years+ - NCT04597437RecruitingPhase 2
Zanamivir for dengue that causes warning signs
This Phase 2 study tests whether zanamivir given through a vein can improve outcomes in people with dengue infection who have warning signs. It may help by reducing the body problems dengue can cause in blood vessels and fluid balance.
Barranquilla, AtlánticoAges 7 years+ - NCT04521699Recruiting
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+ - NCT04505865Recruiting
Mindfulness program to reduce inflammation in heart disease
This trial studies whether a mindfulness (stress-reducing) program can lower “vascular inflammation” (inflammation in blood vessel walls) in people with stable coronary disease. It may help by improving stress and related inflammation markers while you stay on your usual heart medicines.
Boston, MassachusettsAges 45–65 - NCT04321512Recruiting
Blood test study for people with heart or stroke problems
This study looks at a type of white blood cell (monocytes) in blood to understand differences in people with certain heart attacks, stable heart disease, or ischemic stroke. It may help researchers learn why these conditions happen and how the immune system may be involved.
Farmington, ConnecticutAges 18 years+ - NCT04335994Recruiting
Home sleep testing for people with memory trouble
This study looks at how well home sleep apnea testing works for people with cognitive impairment (memory/thinking problems) to help improve outcomes. You may be asked to do a home sleep test (and possibly an in-lab test) and will involve a caregiver if needed.
Toronto, OntarioAges Any age - 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 - NCT04206852Recruiting
Balloon treatment for chronic blood-clot lung vessel disease
This trial tests whether a procedure called balloon pulmonary angioplasty is safe and effective for people with chronic thromboembolic disease in the lungs, especially when surgery isn’t an option. If you have CTEPH, it may help improve lung blood flow and symptoms.
BeijingAges 18 years+ - NCT04077762Recruiting
Radial vs femoral access to reduce bleeding in heart procedures
This study compares two ways doctors can reach the heart during a catheter procedure: through the wrist (radial) or the groin (femoral). It aims to reduce bleeding and access-site complications, especially when patients may need a balloon/stent (PCI).
San Francisco, CaliforniaAges 18 years+ - 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 - NCT03882580Recruiting
Heart care during cancer treatment
