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 - NCT07510451Recruiting
Predicting low blood pressure during major aortic surgery
This trial tests a new monitoring tool that predicts drops in blood pressure before they happen during major aortic surgery. It may help doctors keep your blood pressure more stable during the procedure.

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+ - 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 - NCT07511673Recruiting
Dental screening before heart valve surgery
This trial tests whether a dental checkup before heart valve surgery can improve recovery and prevent complications. If you are scheduled for a heart valve procedure, you may be able to join.
GothenburgAges 18 years+ - NCT07512609Recruiting
How Environment and Inflammation Affect Metabolic Health
This study explores how environmental factors and inflammation in your body might contribute to metabolic diseases like diabetes and heart disease. Researchers will analyze health data from people who've had physical exams to find patterns that could help prevent or manage these conditions.
ChongqingAges Any age - NCT07512739Recruiting
Sitting Tai Chi for Stroke Survivors With Cognitive Changes
This study tests whether a sitting tai chi program can help people who've had a stroke and are experiencing memory or thinking problems. You would learn tai chi movements while sitting, with your caregiver also participating in the program.
Kunming, YunnanAges 18 years+ - NCT07512830Recruiting
Using Hypnosis to Help During Heart Ultrasound
This study tests whether hypnosis (guided relaxation) can help patients feel more comfortable and less anxious during a heart ultrasound procedure that looks at the heart from inside the throat. The goal is to see if it reduces discomfort and the need for sedating medications.
Paris, Île-de-France RegionAges 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.

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 - NCT07513883RecruitingPhase 4
Reducing Heart Failure Medications When Your Heart Recovers
This study tests whether patients whose heart failure has improved can safely reduce some of their medications. If your heart function has recovered significantly and stayed stable, this trial explores whether you can gradually lower doses of heart failure drugs while staying healthy.
