Exercise comparison for muscle loss after stroke
This trial compares two types of leg exercise programs (high-intensity vs. moderate-intensity interval training) to see which better helps rebuild muscle strength and function in people who have had a stroke within the past 1 to 6 months.
Istanbul, AtaşehirAges 18–80 - NCT07457970Recruiting
Health coaching to lower heart risk for women after pregnancy high blood pressure
This trial tests whether a community health worker can coach women who had high blood pressure during pregnancy to lower their future heart disease risk. It starts during pregnancy and continues after delivery.
Columbia, South CarolinaAges 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+ - 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 - NCT07458815Recruiting
Vitamin D for stroke recovery after brain bleed
This trial tests whether vitamin D supplements can help people recover after a specific type of stroke (intracerebral hemorrhage). It is for adults who had a moderate-sized bleed in the upper part of the brain within the last 4 days and were otherwise independent before the stroke.
Hong KongAges 18–90 - 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+ - 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.
Hong KongAges 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+ - 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 - NCT07460531Recruiting
Physical activity and heart health in chronic heart failure
This study looks at how physical activity affects heart outcomes in people with chronic heart failure. If you have a pedometer or activity tracker, you may be able to join.
Munich, BavariaAges 18 years+ - 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+ - 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+ - 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 - NCT07461415Recruiting
Telehealth coaching for high-risk hypertension
This trial tests whether community health workers can help people with very high blood pressure manage it better through phone calls and home visits. It may help you if you have had a dangerously high blood pressure reading in the emergency room but do not have serious organ damage.
Karachi, SindhAges 18 years+ - NCT07462260RecruitingPhase 2/Phase 3
Sildenafil for severe pulmonary hypertension from rheumatic valve disease
This trial tests if sildenafil can help people with severe pulmonary hypertension caused by rheumatic valvular heart disease. It aims to see if the drug improves symptoms and heart function.
Hyderābād, SindhAges 18 years+ - NCT07462741Recruiting
Education program for diabetic hemodialysis patients
This study tests if a special education program helps people with diabetes who are on hemodialysis (a type of kidney treatment). The goal is to see if learning more about managing their health can improve their overall well-being.
Elâzığ, MerkezAges 18 years+ - NCT07462910Recruiting
Checking diaphragm nerve function after pulsed field ablation
This study looks at how a new type of catheter ablation (pulsed field ablation) for atrial fibrillation affects the phrenic nerve, which controls the diaphragm. Researchers will use X-rays to see if the treatment causes any temporary diaphragm problems.
MontrealAges 18 years+ - NCT07463014Recruiting
Peer support for stroke recovery
This trial tests whether getting support from a trained peer coach who has also had a stroke can help you recover better. It's designed for people who have had a stroke and recently left the hospital.
SingaporeAges 21–99 - NCT07463664Recruiting
Drug-coated balloons for blocked heart arteries
This trial tests whether a drug-coated balloon, used without a permanent stent, can safely open completely blocked heart arteries that have been blocked for at least 3 months. It may offer an option that avoids leaving a metal stent behind.
Beijing, Beijing MunicipalityAges 18–80 - NCT07464106Recruiting
Tricuspid valve treatment study for older adults
