Early discharge after TAVI using heart monitoring
This study tests if patients who have mild heart electrical changes after TAVI can be sent home early with a portable heart monitor instead of staying in the hospital. It aims to see if this approach is safe and effective.
BarcelonaAges 18 years+ - NCT07460882Recruiting
Low sodium salt substitute and potassium levels in high blood pressure
This study tests whether using a low-sodium salt substitute can keep your potassium levels safe while you manage your high blood pressure. It's for adults with high blood pressure who are already on stable medications.
DhakaAges 18 years+ - NCT07454135Recruiting
Studying heart muscle disease and atrial fibrillation
This trial looks at how the heart's electrical signals work in people with hypertrophic cardiomyopathy (a condition where the heart muscle becomes thickened) who also have atrial fibrillation (a type of irregular heartbeat). The goal is to understand these signals better during a planned ablation procedure, which is a treatment to fix the irregular rhythm.
LondonAges 18–80 - NCT07454317Recruiting
Biofeedback for managing paroxysmal atrial fibrillation
This trial tests whether biofeedback—a technique that helps you learn to control your body's stress responses—can help people with paroxysmal atrial fibrillation (a type of irregular heartbeat that comes and goes) manage their condition better. If you have this kind of AFib and are otherwise stable, this study may be a good fit.
Liverpool, MerseysideAges 18 years+ - NCT07458880Recruiting
Triple blood pressure pill after a brain bleed
This trial tests whether a combination of three blood pressure medicines can better control blood pressure after a brain bleed (intracerebral hemorrhage). It may help prevent another bleed or stroke.
Hong Kong, Hong KongAges 18 years+ - NCT07458503Recruiting
Brain stimulation plus arm therapy for stroke recovery
This study tests a new combination treatment for people who had a stroke more than six months ago and still have arm weakness. It uses a gentle electrical current on the head (tDCS) along with a therapy that encourages use of the affected arm. The goal is to improve arm movement and daily function.
Belém, ParáAges 40–80 - NCT07456085Enrolling by invitationPhase 3
Rivaroxaban vs warfarin for mechanical heart valves
This trial compares a newer blood thinner (rivaroxaban) to the standard one (warfarin) for people with mechanical heart valves who have had clots or bleeding while on warfarin, or who cannot easily monitor their INR levels. It aims to see if rivaroxaban is safer and more effective.
Rawalpindi, Punjab ProvinceAges 18 years+ - NCT07461415Recruiting
Telehealth coaching for high blood pressure
This trial tests whether support from community health workers through phone calls or in-person visits can help people with very high blood pressure manage their condition and avoid complications. It may be a good fit if you had a very high blood pressure reading in the emergency room and are otherwise stable.
Karachi, SindhAges 18 years+ - NCT07460960RecruitingPhase 2
Statin therapy for heart health and erectile function in men
This study tests whether statins, a common cholesterol-lowering medication, can improve erectile function and hormone levels in men at high risk for heart problems. It aims to see if these benefits exist beyond just lowering cholesterol.
MoscowAges 40–65 - NCT07460700Recruiting
Study of markers for mesenteric artery disease
This study looks at markers for mesenteric artery disease, a condition that affects blood flow to the intestines. It aims to improve diagnosis for people who may have this problem.
MinskAges 18 years+ - NCT07458074Recruiting
Italian Study on Radial VAD Support
This study looks at how well continuous-flow heart pumps (VADs) work in people with advanced heart failure. It aims to improve care and outcomes for adults receiving these devices.
Bergamo, BergamoAges 18 years+ - NCT07453940Enrolling by invitation
Closing off heart pouch with or without pulsed energy in atrial fibrillation
This study tests if adding a special energy treatment (pulsed field ablation) to a standard heart pouch closure is safe and works better for people with persistent atrial fibrillation who have few symptoms but a high risk of stroke.
Hangzhou, ZhejiangAges 18 years+ - NCT07462624Recruiting
Comparing treatments for a failing surgical aortic valve
This trial compares two ways to treat a failing aortic valve that was replaced with a tissue valve during surgery: another surgical replacement or a less invasive catheter-based valve-in-valve procedure. It is for people with low to intermediate surgical risk who are between 18 and 75 years old.
Leipzig, SaxonyAges 18–75 - NCT07458516Recruiting
Observing eye disease progression in type 2 diabetes
This study closely follows people with type 2 diabetes who have early signs of diabetic retinopathy (damage to the retina from diabetes) to see how the condition changes over time. It does not test a new treatment but monitors the eye's health closely. It may be a good fit if you have diabetic retinopathy that does not need immediate treatment.
CoimbraAges 35–80 - NCT07458308Enrolling by invitation
Blended care vs. traditional rehab after stroke or brain injury
This trial compares a new approach that combines in-person therapy with digital support to standard outpatient rehabilitation for people recovering from stroke or brain injury. The goal is to see if blended care works as well or better than traditional rehab.
LucerneAges 18–80 - NCT07459387Recruiting
Real-world results of a new balloon-in-basket pulsed field ablation catheter for atrial fibrillation
This study tracks patients who have atrial fibrillation and receive a new type of ablation therapy using a special balloon that delivers short electrical pulses. It aims to see how well this new device works in everyday medical practice.
FrankfurtAges 18 years+ - NCT07454005Enrolling by invitation
Laser tool for wrist artery access in children
This study tests a new laser-guided tool to help doctors place a small tube in the wrist artery of babies and young children during surgery. It aims to make the procedure faster and safer for your child.
Changchun, JilinAges 1 day–2 years - NCT07454382RecruitingPhase 2
Study of elranatamab and cyclophosphamide for multiple myeloma
This trial studies a new medicine called elranatamab combined with the chemotherapy drug cyclophosphamide for people with multiple myeloma that has returned or not responded to prior treatments. It may be a good option if you have aggressive or high-risk myeloma.
Basking Ridge, New JerseyAges 18 years+ - NCT07460804Recruiting
Sit to stand study for chronic stroke survivors
This trial tests a specific exercise to help people who had a stroke more than 6 months ago improve their ability to stand up from a chair. It may help you if you have some trouble but can still do the movement with minimal or no help.
Cullowhee, North CarolinaAges 18 years+ - NCT07456293Recruiting

Testing ear nerve stimulation for depression after a heart attack
This trial tests if a gentle, non-invasive ear stimulation device can help relieve depression in people who have had a heart attack and a stent placed. It aims to offer a drug-free option for those who choose not to take antidepressants or see a therapist.
Xi'an, ShaanxiAges 18 years+ - NCT07460037Recruiting
Brain signal study for speech recovery after stroke or injury
This trial uses a special brain-mapping test called high-density ECoG to study how people who have lost speech due to stroke, brain tumor, or ALS can be helped by reading brain signals when they imagine speaking. It may lead to new devices that let people with severe speech problems communicate using only their thoughts.
Hangzhou, ZhejiangAges 20–80 - NCT07460128Recruiting
Mirror therapy for arm recovery after stroke
This study tests if using a mirror to create the illusion of moving your weaker arm can help your real arm recover better after a stroke. It is for people who have had a stroke more than 6 months ago, are 18 to 80, and still have some but not too much movement in their affected arm.
