Exercise plan study for people with high blood pressure, blood sugar, cholesterol, or uric acid
This study tests a tool that helps doctors create personalized exercise plans for people with conditions like high blood pressure, diabetes, high cholesterol, or high uric acid (the "Four Highs"). It could help you stay active and manage your health better.
BeijingAges 18 years+ - NCT07400939Recruiting
Brain stimulation and hand movement training for stroke recovery
This trial tests if combining brain stimulation with watching hand movements can improve hand function in people who had a stroke 6 to 24 months ago. It may help you regain better use of your affected hand.
Kota Kinabalu, SabahAges 18–59 - NCT07401186Recruiting
Stimulation to Improve Sensory Pathways in the Brain and Spine
This study tests whether using electrical stimulation during neck surgery can help improve how the brain and spinal cord process sensory information. It may offer new ways to help people with stroke-related weakness.
Pittsburgh, PennsylvaniaAges 21–75 - NCT07401550Recruiting
Using a smartwatch to check heart health
This study uses a Fitbit smartwatch to track your heart activity and predict your risk for heart problems. You might help researchers learn how everyday wearable devices can spot early signs of heart disease.
Dublin, DublinAges 18 years+ - NCT07402018Recruiting
Aortic balloon pump study
This trial looks at how well the heart's pumping is helped by using an intra-aortic balloon pump, a device inserted to support blood flow in people with cardiogenic shock. It aims to learn more about how the device works and improve care.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07402239Recruiting
Heart failure therapy and monitoring device study
This trial tests a device that treats and monitors heart failure. It may help people with chronic heart failure and reduced heart function who still have symptoms despite standard treatments.
Fuzhou, FujianAges 18 years+ - NCT07402642Recruiting
Early Education to Lower Heart Attack Risk Factors
This trial tests if personalized education after a heart attack helps patients lower their future risk of heart problems. It focuses on people who had an emergency procedure to open blocked arteries.
Las Palmas de Gran Canaria, Las PalmasAges 18 years+ - NCT07403630Recruiting
Tumor chemogenomic profiler for cancer patients of all ages
This trial uses a new testing platform to analyze the genes and proteins in your tumor, aiming to find the most effective treatments for people with cancer that has come back, is not responding to treatment, or has spread. It is designed for both children and adults with any type of blood cancer or solid tumor.
Palermo, PalermoAges 1 year+ - NCT07403669Recruiting
Heart, kidney, and metabolic health assessment study
This trial offers a health assessment and empowerment program for adults who have heart, kidney, or metabolic conditions like diabetes or heart disease. It aims to help you better manage your health.
Chandler, ArizonaAges 18 years+ - NCT07404761Recruiting
Moving your arm after stroke or TBI
This study tests a device that uses mild electrical pulses and augmented reality (a computer overlay on real life) to help people who have arm or hand weakness after a recent stroke or brain injury regain movement.
HaifaAges 18 years+ - NCT07404774Recruiting
stitch and laser treatment for hemorrhoids
This trial is testing a combined treatment for hemorrhoids that are causing symptoms. It uses a technique to stitch the hemorrhoid tissue back in place (suture mucopexy) plus a laser to shrink blood vessels. The goal is to see if this approach works well for people with grades II, III, or IV hemorrhoids, even if they've had other treatments before.
AthensAges 18 years+ - NCT07404852Recruiting
Vagus nerve stimulation for reducing inflammation after stroke
This trial tests whether a non-invasive device that stimulates the vagus nerve can reduce inflammation and brain injury after a stroke caused by a large blood clot.
St Louis, MissouriAges 18–99 - NCT07405229RecruitingPhase 4
Medical treatment for idiopathic ventricular fibrillation patients
This study tests medical treatments for people who survived a cardiac arrest with a specific heart rhythm problem called idiopathic ventricular fibrillation. If your cardiac arrest was likely from a heart issue but not from clogged arteries, you might help find better treatments.
Copenhagen, Dr.Ages 18 years+ - NCT07405242Recruiting
Treatment for retrograde aortic dissection with a stent graft
This trial tests a stent-graft procedure for a specific type of aortic dissection where the tear starts in the arch or descending aorta and extends backward into the ascending aorta. It is for patients who are not good candidates for open surgery.
Shanghai, Shanghai MunicipalityAges 65 years+ - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children
This study compares simple coughing exercises with a breathing device (incentive spirometry) to help children recover lung function faster after heart surgery. It may help reduce complications and shorten hospital stays.
