AmsterdamAges 18 years+ - NCT07237542Recruiting
Remote ischemic preconditioning for small stroke prevention
This study tests whether a simple, non-invasive treatment called remote ischemic preconditioning (using brief periods of blood pressure cuff inflation on the arm) can help prevent early neurological worsening in people who have had a small, specific type of stroke. It may offer a safe way to protect your brain while you recover.

Early heart disease trial for women and men with mild plaque buildup
This trial tests whether two medicines, a statin and colchicine, can slow or stop early heart artery plaque from growing in people who have mild plaque but no heart disease symptoms yet. It uses special CT scans to measure plaque over 2 years.
Birmingham, AlabamaAges 30–60 - NCT07230886Recruiting
Reducing transplant complications with enhanced preservation
This trial tests a new way to preserve donated lungs before transplant to lower the risk of complications. It may help primary graft dysfunction, a serious lung problem after surgery.

Walking rehabilitation after stroke: Exoskeleton vs treadmill
This study compares two robotic devices (the LoKomat exoskeleton and the C-Mill treadmill) to see which one helps people walk better after a stroke. If you are recovering from a stroke and able to understand instructions, you may be able to join.
SalamancaAges 18–65 - NCT07232498Recruiting
Early ultrasound-guided movement after a stroke
This trial tests if starting supervised mobility early (within 48 hours) using Doppler ultrasound to guide care can help recovery in adults who just had a stroke caused by a clot. It may help you avoid complications and regain function sooner.
RijekaAges 18 years+ - NCT07235514Recruiting
Anesthesia management during clot removal for stroke
This trial compares different types of anesthesia given during mechanical thrombectomy (clot removal) for people who have a severe ischemic stroke from a large artery blockage. Researchers want to see which anesthesia approach leads to better recovery.
AngersAges 18 years+ - NCT07234565Recruiting
Improving social frailty through interactive learning
This trial tests a social program delivered over WeChat to help older adults with heart failure who feel socially frail. It aims to improve social connections and reduce frailty through interactive learning.
ShanghaiAges 60 years+ - NCT07236398Enrolling by invitation
Modified left atrial maze procedure for atrial fibrillation
This trial tests a modified maze procedure to treat atrial fibrillation during heart surgery. It may help patients with AFib who are already scheduled for cardiac surgery.
Toulouse, French (France)Ages 18 years+ - NCT07231172Recruiting
Fatigue after stroke and its link to clinical factors
This study examines how fatigue affects people who have had a stroke, looking at physical and mental health factors. It may help understand why some people feel more tired than others after a stroke.
AnkaraAges 18 years+ - NCT07236021Recruiting
e-Motion: emotion support for chronic cancer patients
This trial tests an online program called e-Motion that helps people with chronic cancer manage their emotions. It may help you feel more in control and better cope with your diagnosis and treatment.
Brussels, AnderlechtAges 18 years+ - NCT07232017Recruiting
Intensive blood pressure management study at Cleveland Clinic
This trial tests a program to help people with high blood pressure get it under better control. If you have high blood pressure that is not well-managed, this study may offer extra support and monitoring.
Cleveland, OhioAges 18–85 - NCT07238920Recruiting
Brain training for heart health in people with coronary artery disease and anxiety
This trial tests a brain-training technique called neurofeedback, which uses a video game controlled by your brain activity to help your heart and nervous system work better. It is for people with both coronary artery disease and anxiety who want to improve their heart health and manage anxiety without medication.
Shenyang, LiaoningAges 18 years+ - NCT07236879Recruiting
AI eye test for diabetes patients in primary care
This trial uses an artificial intelligence (AI) system to check for diabetic eye disease (retinopathy) during your regular doctor visit. It aims to detect problems early so you can get treatment sooner.
Porto Alegre, Rio Grande do SulAges 18 years+ - NCT07231380Recruiting
Comparing two ways to remove clots in stroke
This study tests two methods of removing a large blood clot from a brain artery during stroke. The goal is to see which method helps restore blood flow faster and more safely.
Nashville, TennesseeAges 18 years+ - NCT07231939Recruiting
