Robot-assisted arm therapy after recent stroke
This study tests whether a robot-assisted therapy program can help people recover arm and hand movement after a recent stroke. If you had a stroke less than 3 months ago and have some weakness in your arm but can still move it a little, this trial may help you regain function.

Stress echo's positive value in heart health
This study looks at how well a stress echocardiogram (heart ultrasound during exercise or medication) predicts future health in people who have some sign of reduced blood flow to the heart. The goal is to confirm that a positive stress echo is a good sign for guiding next steps.
Athens, AtticaAges 18–100 - NCT06840405Recruiting
Brain activity during walking after stroke
This study looks at how the brain works while walking in people who have had a stroke. It may help researchers understand walking problems better.
TaipeiAges 20–80 - NCT06842095Recruiting
Stimulation therapy for stroke recovery
This trial tests if a non-invasive brain stimulation technique can improve arm movement recovery after a stroke. It is for people who had a stroke affecting their arm and are at least 3 months past the stroke.
OxfordAges 18 years+ - NCT06842147Recruiting
AI Heart Monitor for New Atrial Fibrillation Detection
This trial uses a special long-term heart monitor (one wire) that uses artificial intelligence to find new cases of atrial fibrillation, a type of irregular heartbeat that can increase stroke risk. If you're 60 or older and haven't had AF before, this study could help catch it early.
Zhejiang, QuzhouAges 60 years+ - NCT06842446Recruiting
Fast detection of blood clots using machine learning
This trial tests whether a machine learning algorithm can quickly detect deep vein thrombosis (blood clots) in people coming to the emergency room. It could help speed up diagnosis and treatment.
SarpsborgAges 18 years+ - NCT06842745RecruitingPhase 2
Brain stimulation plus language therapy for mild aphasia
This study tests whether combining brain stimulation (TMS) with language therapy can help people with mild aphasia after a stroke. It aims to improve speaking and understanding.
Philadelphia, PennsylvaniaAges 40–85 - NCT06842875Recruiting
Postpartum blood pressure monitoring study in Rhode Island
This study tests whether remote blood pressure monitoring after childbirth helps manage high blood pressure. It may be an option if you had high blood pressure during or after pregnancy.
Newport, Rhode IslandAges 18–60 - NCT06843005Recruiting
Heart CT scan study for plaque changes in mild coronary disease
This study uses repeat CT scans of the heart to see how plaque buildup changes over time in people with mild, non-blocking coronary artery disease. It may help doctors decide on better treatments to prevent future heart problems.
Nanjing, JiangsuAges 18–80 - NCT06843499Recruiting
AI eye screening for AMD and diabetic retinopathy
This trial tests an AI program called VeriSee that helps doctors check for eye problems like age-related macular degeneration (AMD) and diabetic retinopathy (DR). It compares the AI's accuracy and costs to standard care in regular eye clinics.
Taipei, TaiwanAges 20 years+ - NCT06843616Recruiting
Study of a disposable brain clot removal scope for bleeding stroke
This study tests a new disposable tube with a camera (endoscope) that doctors use to remove a blood clot from the brain after a bleeding stroke. It is designed for people who are stable enough for surgery and whose bleed is in a part of the brain that is reachable with this tool.
Guiyang, GuizhouAges 18–80 - NCT06844032Recruiting
Predictors of poor outcome in heart failure with normal pumping
This study looks at people with heart failure who still have a normal pumping ability (HFpEF). Researchers want to find what factors predict a worse outcome, so they can better understand and treat this condition.
MoscowAges 40 years+ - NCT06844227Recruiting
Virtual Visit to Manage Blood Thinners Around Surgery
This study looks at whether a virtual visit can safely manage your blood thinners around the time of a planned surgery. You would stop your medication before the procedure and restart it after, but all instructions and check-ins happen remotely (phone or video).
Evanston, IllinoisAges 18–100 - NCT06844851Recruiting
Genetic causes of cardiac arrest in young adults
This study looks at the genetic causes of cardiac arrest that happens outside the hospital in younger people. If you or a family member had a cardiac arrest before age 50 in Lombardy, Italy, researchers may test your DNA to find inherited risks that could affect other family members.
Pavia, PaviaAges 18–50 - NCT06844942Recruiting
Improving heart artery imaging for chest pain diagnosis
This trial uses a special camera called OCT to take detailed pictures of the heart's arteries. It aims to see if these pictures help doctors better understand blockages and decide on treatment for stable chest pain.
Warsaw, Mazowieckie VoivodenshipAges 18 years+ - NCT06845371Recruiting
MELODY registry follow-up study
This study is for people who have already joined the MELODY registry. It will simply continue to collect information about their condition over time to help researchers better understand how things change.
TübingenAges Any age - NCT06845410Recruiting
INR-CAD: inflammation-related coronary artery disease study
This study follows people who have both coronary artery disease (narrowed heart arteries) and signs of chronic inflammation to learn more about their condition, current treatments, and outcomes. It helps doctors understand how best to care for patients like you.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06845423RecruitingPhase 4
Preventing blood clots after childbirth in women at intermediate risk
This study tests whether giving a short course of a daily blood-thinning injection (enoxaparin) after childbirth can safely prevent blood clots in women at intermediate risk. If you qualify, you would receive the injection or a placebo (inactive shot) for up to 5 days while in the hospital.
AmiensAges 18 years+ - NCT06845436Recruiting
Interval and strength training for high blood pressure
This trial tests whether combining intense interval training with strength training can help middle-aged men with high blood pressure and obesity improve their health. You may benefit if you are a man between 40 and 60, have stage 1 or 2 hypertension, and are not currently active.
Riyadh, AlkharjAges 40–60 - NCT06845514Recruiting
Can strength training help lower blood pressure?
