Mobile brain/body imaging for robotic gait rehab after stroke
This trial uses a mobile brain and body imaging system to help improve walking with a robotic exoskeleton in people who have had a stroke. It could help you walk better during overground gait training.
Costa Masnaga, LeccoAges 18 years+ - NCT07514962Recruiting
Minimally invasive heart bypass surgery with a blood-thinner medication
This trial tests whether a blood-thinner drug called cangrelor helps patients who are having a special type of bypass surgery that uses a small incision instead of opening the whole chest. The surgery connects a healthy artery from your chest wall directly to a blocked heart vessel to restore blood flow.
Lugano, Ch/tiAges 18 years+ - NCT07512778Recruiting
Heart stent placement guided by ultrasound vs. imaging
This trial compares two ways doctors place heart stents in patients having a heart attack or unstable chest pain. One method uses ultrasound imaging inside the artery (IVUS), and the other uses standard X-ray imaging. The goal is to see which approach leads to better outcomes.
Seoul, Eunpyeong-guAges 19–90 - NCT07508891Recruiting
Studying heart failure types in hospitalized patients
This trial looks at different types of acute heart failure in people who are hospitalized. Doctors will study your symptoms and health to better understand heart failure patterns, which might help improve future treatments.
HamburgAges 18 years+ - NCT07509645RecruitingPhase 3
Testing a new drug with clot removal for severe back-of-the-brain stroke
This trial checks if adding an interleukin-6 receptor inhibitor (a drug that reduces inflammation) to standard emergency clot removal can improve recovery for people with a severe stroke affecting the back part of the brain (posterior circulation). It is for patients who need urgent treatment within 24 hours of symptom onset.
Huaibei, AnhuiAges 18 years+ - NCT07512960RecruitingPhase 3
Blood Thinner Duration After Leg Artery Treatment
This trial tests how long patients should take two blood-thinning medications (aspirin and clopidogrel) after treatment to restore blood flow to a severely damaged leg. The goal is to find the right balance between preventing clots and avoiding dangerous bleeding.
Paris, Île-de-France RegionAges 18–99 - NCT07508618RecruitingPhase 4
Qidong Yixin Granule for preventing atrial fibrillation after ablation
This trial tests whether a traditional Chinese medicine granule, Qidong Yixin, can help prevent atrial fibrillation from coming back after a heart ablation procedure. It is for people with persistent atrial fibrillation who have not had good results from other heart rhythm medications.
HangzhouAges 18–80 - NCT07509944Recruiting
Brain activity in stroke patients during mirror movement
This study uses a brain imaging technique called functional near-infrared spectroscopy (fNIRS) to look at how the brain works when stroke patients perform mirror movements. It aims to help understand brain recovery after a first-time stroke.
HangzhouAges 18–75 - NCT07508865Recruiting
Sustainable anesthesia for heart bypass surgery
This trial studies a sustainable anesthesia approach for people having planned coronary artery bypass graft surgery (a type of open-heart surgery to improve blood flow to the heart). It aims to see if this method is safe and effective for patients at the study hospital.
Temuco, AraucaniaAges 18 years+ - NCT07513974Recruiting
Pain sensitivity test to predict opioid needs in heart surgery
This study measures how sensitive you are to pain using a special device, then tracks how much pain medication you need during heart surgery. The goal is to see if pain sensitivity can predict opioid requirements and help doctors customize pain control for you.
Brussels, AnderlechtAges Any age - NCT07511257RecruitingPhase 4
Blood thinners after heart attack with widened arteries
This trial tests two different blood-thinner strategies for people who have had a recent heart attack and also have a widened artery (ectasia) in the heart. The goal is to find the safest and most effective way to prevent another heart attack or clot.
Mexico City, TlalpanAges 18–80 - NCT07515508Recruiting
Understanding heart failure patterns in hospitalized patients
This study investigates different types of acute heart failure in hospitalized patients to better understand their condition and improve treatment. Researchers will use multiple imaging and testing methods to create a detailed picture of each patient's heart failure.
Bad KrozingenAges 18 years+ - NCT07515040Recruiting
AccuSafe guidewire versus needle for heart rhythm procedure
This trial compares two different tools used during a minimally invasive heart procedure to treat atrial fibrillation (an irregular heartbeat). The study tests whether a newer guidewire tool is safer and works as well as the traditional needle approach.
Nanchang, JiangxiAges 18–75 - NCT07507500RecruitingPhase 4
Comparing blood thinners and treatment length after a heart attack
This trial compares two common blood-thinning medications (prasugrel vs ticagrelor) and two treatment durations (short 1–3 months vs standard 12 months) after a heart attack treated with stents. It aims to find the most effective and safest anti-clotting strategy for patients.
DublinAges 18 years+ - NCT06688201Recruiting
Minimally invasive clot removal for large brain bleed
This trial tests a minimally invasive surgery (soft channel drainage) to remove a large blood clot deep in the brain after a stroke. It is for people who can have the procedure within 48 hours of bleeding and whose consciousness is reduced but not completely gone.
Linyi, ShandongAges 18–80 - NCT06759428Recruiting
Chronic subdural hematoma patient registry study
This study collects information from patients diagnosed with chronic subdural hematoma (a type of bleeding on the brain) to better understand the condition and its treatment. By participating, you help doctors learn more about what helps patients recover.
AmsterdamAges 18 years+ - NCT06764290Recruiting
Brain changes when walking after stroke
This study looks at how the brain changes after a stroke when people walk on different surfaces. It may help understand why walking can be harder and how therapy could improve it.
Nanjing, JiangsuAges 18–70 - NCT06761144Recruiting
Detecting blood clots in lungs of cancer patients in the ER
This trial studies how to quickly and safely rule out blood clots in the lungs of cancer patients who come to the emergency room. It aims to help doctors make faster decisions and avoid unnecessary treatments for people with cancer.

Drug-coated balloon for dialysis fistula narrowing
This trial tests a special balloon that releases medication to help keep your dialysis fistula (the blood vessel used for treatment) open longer if it has narrowed. It may be a good option if you have a blockage in the vein side of your fistula that causes problems during dialysis.
Hefei, AnhuiAges 18–80 - NCT07499661Recruiting
Study of blood clots in the lungs with heart failure
This study looks at whether a blood clot in the lungs (pulmonary embolism) is a hidden cause in patients who are hospitalized for acute heart failure. It involves additional imaging tests to find a clot if present, which could change your treatment.
