Vagus Nerve Stimulation With Rehab to Improve Walking After Stroke
This study tests whether vagus nerve stimulation (a small device that stimulates a nerve in your neck) combined with rehabilitation therapy can help improve walking and leg function in stroke survivors. You would be one of the first to try this combination approach for stroke recovery.
Buffalo, New YorkAges 22–80 - NCT07643610Recruiting
Heart Failure Crisis Registry Study
This registry collects information from patients admitted to the hospital with cardiogenic shock—a serious condition where the heart cannot pump enough blood to the body. Doctors will gather data to better understand what happens to these patients and how to improve their care.

Blood test for pregnancy risk assessment using fetal cells
This study tests a new blood test that looks for fetal cells in your bloodstream to check your baby's health during pregnancy. The test is non-invasive—just a regular blood draw—and aims to help identify pregnancy risks earlier than traditional methods.
Phoenix, ArizonaAges Any age - NCT07644715Recruiting
AI Analysis of Heart Rhythms and Immune-Related Heart Damage
This study uses artificial intelligence to analyze heart electrical recordings (ECGs) from existing patient databases to better detect dangerous heart rhythm problems and heart inflammation caused by cancer immunotherapy. Researchers are not giving any new treatments—they're studying existing data to improve diagnosis.
ParisAges Any age - NCT07646418Recruiting
Light therapy and blood-flow restriction for stroke recovery
This study tests whether combining light therapy with blood-flow restriction exercise (a technique that limits blood flow during gentle movement) helps improve arm strength and reduce muscle stiffness in people recovering from stroke. The goal is to see if this combination works better than standard treatment.
Sialkot, Punjab ProvinceAges 50–70 - NCT07646522RecruitingPhase 2
Home-Based Arm Recovery Program After Stroke in Brazil
This study tests whether telehealth (video-guided) exercises can help people recover arm function after a recent stroke. You'll do exercises at home with remote support and guidance, and researchers will track your progress over 6 weeks.
Ribeirão Preto, São PauloAges 18–80 - NCT07646704Recruiting
Study of HeartR PDA Heart Device Safety and Function
This study follows patients who had a small heart device (HeartR PDA Occluder) placed to close an opening in their heart called a PDA. Researchers will check how well the device is working and track the patient's health over time.
Pekanbaru, RiauAges 6 months+ - NCT07647497Recruiting
Heart Imaging to Predict Outcomes in Pulmonary Embolism
This study uses ultrasound images of your heart to see how well the right side is working in people who have a blood clot in the lungs. The goal is to better predict which patients might be at higher risk and need more intensive care.
SohagAges 18 years+ - NCT07648693Recruiting
Brain Protection Device During Aortic Valve Replacement
This trial tests a new device called CHORDS that protects your brain during transcatheter aortic valve replacement (TAVR), a minimally invasive procedure to fix a narrow aortic valve. The device works by blocking debris that might travel to your brain during the procedure.
Bengbu, AnhuiAges 18 years+ - NCT07649109RecruitingPhase 4
Heart Device Detected Irregular Heartbeats: Treatment Study
This study follows patients who have a heart rhythm device (pacemaker, defibrillator, or resynchronization device) and have experienced brief episodes of fast irregular heartbeats detected by the device. The study compares treatment approaches to understand which helps patients stay healthier and feel better.
TaipeiAges 18 years+ - NCT07649148Recruiting
Tracking What You Eat to Help Your Heart
This study asks people with moderate heart failure to use a food-tracking app and work with a coach to eat fewer ultra-processed foods. Researchers want to see if changing your diet this way can improve how you feel and how well your heart works.
Cleveland, OhioAges 18 years+ - NCT07649330Recruiting
Myofascial Release for Heart Surgery Recovery
This study tests whether a hands-on soft-tissue massage technique can help reduce pain and stiffness in patients recovering from open-heart surgery. The goal is to see if it speeds up healing and improves quality of life after the procedure.
