Testing wearable watch and pillow devices for blood pressure monitoring
This study tests two wearable devices—a watch and a pillow—that measure blood pressure and other health signals. It aims to see how well they work compared to standard hospital equipment. If the devices are accurate, they could make daily blood pressure tracking easier and more comfortable.
Louisville, ColoradoAges 50–80 - NCT07753174Recruiting
Omega-3 supplement study for healthy adults
This study tests a supplement containing omega-3 fats to see how it affects levels of DHA and EPA in your blood. If you're a healthy adult, you might join to help learn if this supplement can boost these important fats.

New study drug compared with metoprolol for hypertrophic cardiomyopathy
This trial compares a new study drug (BHB-1893) with a standard heart medication called metoprolol to see which one better improves symptoms in people with obstructive hypertrophic cardiomyopathy. If you join, you will be randomly assigned to receive either the study drug or metoprolol, and your symptoms and heart function will be monitored over time.
Manhasset, New YorkAges 18–85 - NCT07754318Recruiting
EndoAnchor treatment for abdominal aortic aneurysm
This trial tests a device called EndoAnchor, which is used during surgery to help secure a stent graft in place for people with an abdominal aortic aneurysm. It aims to improve the seal and reduce complications, potentially helping people whose aneurysm shape makes standard treatment riskier.
BeijingAges 18 years+ - NCT07750873RecruitingPhase 2
Study of an investigational medicine for heart failure with reduced pumping function
This trial tests an investigational medicine called CRD-4730 (taken as a pill) to see if it can improve heart function and symptoms in people with heart failure and a reduced pumping ability. It may help you feel better and slow the progression of your condition.
Pasadena, CaliforniaAges 18–85 - NCT07754240Recruiting
Stent graft for abdominal aortic aneurysm
This trial tests a new stent graft device for treating abdominal aortic aneurysms. The device is placed inside the aneurysm to reinforce the artery and prevent rupture, which may help people who are candidates for this minimally invasive procedure.
PlevenAges 18–80 - NCT07749820Recruiting
Clot removal device for leg vein blood clots
This study tests a device that removes blood clots from the deep veins of your leg. It's designed to help people with recent or slightly older clots in the thigh or pelvic area, aiming to reduce symptoms and prevent complications.
ShanghaiAges 18 years+ - NCT06479343Recruiting
Liquid embolic for brain vessel malformations
This trial tests a new liquid material (called a liquid embolic system) that is injected into the abnormal blood vessels in the brain to block them off. It is for people who have a cerebrovascular malformation and can be treated with a catheter from inside the blood vessel.
Guangzhou, GuangdongAges 18–80 - NCT06539832Recruiting
Gut bacteria and immunity in people with an abnormal blood protein
This study looks at how your gut bacteria (intestinal flora) and immune system relate to a condition called monoclonal gammopathy, where an abnormal protein is found in the blood. The trial will check samples from your blood, plasma, and stool to understand these connections.
Guanzhou, GuangdongAges 45 years+ - NCT06577896Recruiting
Onyx stent safety and effectiveness in older adults
This study looks at how well a specific brand of heart stent (Onyx) works in people 75 and older who have narrowed heart arteries. If you've already received an Onyx stent, the study will check its safety and effectiveness over time.
