This study observes how the Achilles tendon works during walking in people who have had a stroke, a spinal cord injury, or in healthy volunteers. It aims to better understand gait problems.
NantesAges 18 years+ - NCT07468123Enrolling by invitation
Estimating Atrial Fibrillation Risk With a Handheld ECG
This trial uses a simple, handheld ECG device (like a small card) to check your risk for atrial fibrillation, a common irregular heartbeat. You'll record short heart tracings at home, and the study team will review them to find hidden risk factors.
Boston, MassachusettsAges 18–90 - NCT07469943Recruiting
Diabetes drug after heart attack
This study tests whether a diabetes medication can improve artery health and heart function after a heart attack. It is for people who have had a STEMI and also have diabetes or a weakened heart pump.
Athens, Rimini1/HaidariAges 18–80 - NCT07467785Recruiting
Home-based virtual therapy for stroke survivors with arm weakness
This trial tests whether doing arm exercises at home with a therapist over video can help stroke survivors who have moderate to severe arm problems. It is designed for people who are not already getting outpatient arm therapy.
Edmonton, AlbertaAges 18–80 - NCT07464938Recruiting
Predicting brain recovery after cardiac arrest
This study is testing new tools and markers to better predict recovery after cardiac arrest when brain injury may occur. It involves adults who had a cardiac arrest outside the hospital and are being treated at Saint-Luc hospital.
BrusselsAges 18 years+ - NCT07465640Recruiting
Pulsed magnetic field therapy for diabetic foot ulcers
This trial tests a device called CRAD ULCER X-01 that uses gentle magnetic pulses to help heal diabetic foot ulcers. It may help people with a diabetic foot ulcer that is not too deep and is at an early stage.
Kuala LumpurAges 18 years+ - NCT07467668Recruiting
Iron infusion for heart failure patients with low iron
This trial tests whether giving intravenous iron to adults hospitalized with heart failure and low iron levels helps improve their health. You may be eligible if you have heart failure with reduced pumping function and low iron stores.
Pleasanton, CaliforniaAges 18 years+ - NCT07465549Recruiting
A smarter way to manage hard-to-control high blood pressure
This trial uses a special blood pressure monitor (CART BP Pro) to help guide treatment for people whose blood pressure stays high despite standard care. You may qualify if your blood pressure is still too high even with medication.
AnsanAges 19 years+ - NCT07464379Recruiting
Study on blood pressure during pregnancy
This study looks at pregnancy-induced hypertension (high blood pressure) in pregnant women. It aims to understand how this condition affects health and to find better ways to manage it.
Wenzhou, ZhejiangAges 20–50 - NCT06791915Recruiting
Comparing breathing method during heart ablation for AFib
This trial studies two ways of using a breathing machine during a heart procedure called radiofrequency ablation for atrial fibrillation (AFib). It aims to find which method is better and safer.
KocaeliAges 18 years+ - NCT04576130Recruiting
ICD study after cardiac arrest from an abnormal heart rhythm
This study looks at an implantable defibrillator (ICD) strategy in people who survived a cardiac arrest caused by an abnormal rhythm (ventricular fibrillation or ventricular tachycardia). It aims to reduce the risk of another dangerous rhythm after the blocked heart arteries are fully treated.
CopenhagenAges 18 years+ - NCT05946850Recruiting
Caudal pain block study for adults with chronic pain
This trial looks at giving a specific pain procedure called caudal analgesia to adults with long-term (chronic) pain. It may help reduce pain after the procedure, and it will compare results for people who can safely receive it.
Surrey, British ColumbiaAges 20–99 - NCT05864638Recruiting
Registry study of clot-removal treatment for acute stroke
This study records outcomes for people having an acute ischemic stroke treated with an endovascular (catheter-based) procedure. It may help doctors understand how clot-removal treatment works in different patients and hospitals.
ShanghaiAges Any age - NCT06493227Recruiting
Extended use of bleeding control drugs after heart surgery
This trial is for hospitals, not patients. Hospitals that do many open heart surgeries and whose doctors agree to use certain bleeding control drugs (fibrinolysis inhibitors) as per the study protocol can participate.
Saint PetersburgAges 18 years+ - NCT06792643RecruitingPhase 2
Cangrelor for heart attack patients on heart-lung support
This trial tests whether adding a fast-acting anti-clotting drug (cangrelor) helps people having a massive heart attack who need a heart-lung machine (VA-ECMO). The goal is to see if it reduces clotting risks without causing dangerous bleeding.
Milan, ItalyAges 18 years+ - NCT06793787Recruiting
AI and advanced imaging to guide treatment of borderline heart blockages
This study uses advanced CT scans and a special camera (OCT) to look at borderline blockages in heart arteries more closely. It aims to see if artificial intelligence can help decide which blockages need a stent and which can be treated with medicine alone.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06793774Recruiting
Using CT scans and AI to evaluate heart artery risk
This study uses a CT scan of your heart (CCTA) and advanced computer analysis to see how well it can predict heart risks compared to detailed inside-look tests (IVUS, OCT, NIRS). If you have chest pain and have had certain heart scans, this trial may help doctors understand your condition better.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06793865Recruiting
Stimulation for ankle muscles to improve balance after stroke
This study tests a type of electrical stimulation, called Russian current, on the front shin muscles to see if it helps stroke patients stand steadier and lower their risk of falling.

LeidenAges 16 years+ - NCT06031623Recruiting
Using REBOA for non-traumatic cardiac arrest outside hospital
This study tests if a temporary balloon placed in the aorta, called REBOA, can improve blood flow to the heart and brain during CPR for people whose hearts stop due to a non-traumatic cause. It is for adults who have a witnessed cardiac arrest and arrive at the hospital during daytime hours.
