Therapies to improve arm movement after stroke
This study compares two types of hand and arm therapy for people who have had a stroke. It tests if modified constraint-induced movement therapy or mirror therapy can help improve movement in the affected arm.

This study tests a new device that checks your heart without needles while you are in the hospital for heart failure. It may replace some blood tests and help doctors make treatment decisions more easily.
LundAges 18 years+ - NCT07671898Recruiting
Freezing vs. Radiofrequency for Slow Heart Rate
This trial compares two procedures to treat very slow heart rates without needing a pacemaker. One uses freezing (cryoablation) and the other uses radiofrequency energy to target nerves that control heart rate.

Study on iliac stenting to prevent major leg events
This study looks at people with narrowed or blocked arteries in the pelvis (iliac arteries) who receive a stent to improve blood flow. It aims to understand which factors might predict future serious problems in the legs, like worsening pain or amputation.
Milan, MiAges 18 years+ - NCT07654634Enrolling by invitation
Precision blood thinning therapy study
This trial tests personalized blood thinner treatment for people who need long-term anticoagulation for conditions like atrial fibrillation or blood clots. The goal is to find the safest and most effective dose for each patient.
Changsha, HunanAges 8 years+ - NCT07653165Enrolling by invitation
Wound therapy for chronic leg wounds
This trial is testing a new way to clean and treat chronic leg wounds using a special wound therapy and gentle suction. It may help wounds that have not healed for a long time.
Coconut Creek, FloridaAges Any age - NCT07633548Enrolling by invitation
Simplified sedation protocol for heart rhythm ablation
This trial tests a streamlined sedation approach during pulsed-field ablation, a newer technique to treat irregular heartbeat (atrial fibrillation). Researchers want to confirm it's safe and practical.
CaenAges 18–80 - NCT07625488Enrolling by invitation
Heart Disease Risk Follow-up Study for Former Athletes
This study follows up with people who participated in a heart-health study between 2012 and 2014. Researchers will use heart imaging and exercise tests to check your cardiovascular health and learn more about heart disease risk in athletes.
NijmegenAges 45 years+ - NCT07616622Enrolling by invitation
Recovery Methods for Upper Arm Weakness After Stroke
This study compares two physical therapy approaches—Roods (a sensory-based technique) and PNF (a stretching and strengthening method)—to help improve arm function in people recovering from their first stroke. Both methods aim to help you regain strength and control in your upper arm and hand.
Faisalābad, Punjab ProvinceAges 40–60 - NCT07606768Enrolling by invitation
Nurse coaching to help control high blood pressure
This study tests whether regular phone or video coaching from a nurse helps people with high blood pressure better manage their condition and take their medications. You'll receive personalized guidance to improve your health habits and blood pressure control.
Huayuan, HunanAges 18–85 - NCT07603466Enrolling by invitationPhase 4
Two drugs combined to treat Cushing's disease
This trial tests whether taking two medications together—osilodrostat and cabergoline—can help control Cushing's disease by lowering excess cortisol levels. Cushing's disease is caused by a pituitary tumor that makes too much of a hormone called ACTH, which drives cortisol overproduction.
BasraAges 18–70 - NCT07594808Enrolling by invitationPhase 2
Stress Management App for African American Men with High Blood Pressure
This study tests a mobile stress-management app to help African American men lower their blood pressure. If you have high blood pressure and a smartphone, you may be able to take part from home.
Washington D.C., District of ColumbiaAges 18 years+ - NCT07587437Enrolling by invitation
Magnetic Camera Exam Before Weight-Loss Surgery
This study tests a swallowable magnetic camera to examine your stomach and small intestine before bariatric (weight-loss) surgery. The camera may help doctors plan your surgery and catch any issues beforehand.
Cleveland, OhioAges 18 years+ - NCT07582523Enrolling by invitation
Heart Rhythm Monitoring at Home for High Blood Pressure
This study tests whether wearing a small heart rhythm patch at home can detect irregular heartbeats in people with high blood pressure. It may help catch heart rhythm problems early before they cause symptoms.
San Francisco, CaliforniaAges 60 years+ - NCT07572721Enrolling by invitation
Virtual Fitness and Health Program for Heart Health
