Predicting stomach pain in children with IgA vasculitis
This study looks at a blood test done when a child is first diagnosed with IgA vasculitis (also called Henoch-Schönlein purpura) to see if it can predict stomach or intestine problems. It involves one extra blood draw at diagnosis and a follow-up visit a few weeks later.

Single-lead ECG test for heart electrical intervals
This trial is testing a new algorithm that uses a simple, one-lead ECG (heart tracing) to measure how fast electrical signals travel through the heart. Researchers want to see if the algorithm works well in people whose heart intervals are slightly outside the normal range, which may help doctors better monitor heart conditions.

Ramantamig plus daratumumab for untreated multiple myeloma without stem cell transplant
This trial tests a new combination of two drugs, ramantamig and daratumumab, against other standard treatments for people newly diagnosed with multiple myeloma who are not planning to have a stem cell transplant. The goal is to see if this combination works better at controlling the cancer.
NantesAges 18 years+ - NCT07668687Recruiting
Long-Term Study of Castor and Cratos Stents for Aortic Arch Repair
This study tracks how well two types of stents (Castor and Cratos) work for people who have had a repair of the main artery in the chest (the aortic arch). If you already received one of these stents during your procedure, the study will follow your recovery and any future aortic events.
HamburgAges 18 years+ - NCT07667452Recruiting
AI patch study for heart failure recognition
This trial tests a new AI computer model that uses a single feature from a wearable patch to help recognize heart failure more easily. If you have heart failure with moderate to severe symptoms, this study may help improve how we monitor your condition.
Hangzhou, ZhejiangAges 18 years+ - NCT06674057Recruiting
Taping with physical therapy for arm function after stroke
This study tests whether adding kinesio-taping to standard physical therapy helps improve arm movement and reduce stiffness in people recovering from a recent stroke.
IslamabadAges 40–65 - NCT06674590Recruiting
Stroke rehab: comparing two therapies for balance and walking
This study compares two different exercise-based therapies to see which one helps stroke survivors improve balance and walking better. It is for people who had a stroke more than 6 months ago and can walk a short distance with or without help.
IslamabadAges 25–65 - NCT06675383Recruiting
Screening for atrial fibrillation after stroke
This trial tests whether extended monitoring can detect hidden atrial fibrillation (an irregular heartbeat) in people who have had a stroke. If found, treatment can help prevent another stroke.
Sogneprest Munthe-kaas Vei 100, GjettumAges 18 years+ - NCT07671677Recruiting
BodyGuardian monitoring after AF ablation
This study tests using a portable heart monitor called BodyGuardian to check for atrial fibrillation returning after a procedure called ablation. It may help your doctor find irregular heartbeats early.
Delray Beach, FloridaAges 18 years+ - NCT07668206Recruiting
Talking therapy for thoracic outlet syndrome pain
This study tests if talking with a counselor (motivational interviewing) can help people with long-term pain from thoracic outlet syndrome feel better. It is for adults who have not had surgery recently.
AnkaraAges 18–65 - NCT07669987Recruiting
Heart bypass surgery and artery imaging study
This study looks at whether a special imaging test called QFR, done before heart bypass surgery, can help predict how well the radial artery graft will work shortly after surgery. If you have severe blockages in your heart arteries and are scheduled for bypass surgery, this trial may be relevant.
Beijing, Beijing MunicipalityAges 18–80 - NCT07664748Recruiting
Voice check-ins for heart failure monitoring
This study tests whether analyzing your voice during routine check-ins can help monitor heart failure. You'll use a special app or device to talk to a virtual assistant, which may help detect early signs of worsening heart failure.
Milan, ItaAges 18 years+ - NCT07665034Recruiting
Isometric exercise for high blood pressure and artery health
This study tests whether a specific type of exercise (isometric exercise) can help slow down the buildup of plaque in arteries (atherosclerosis) in people with high blood pressure. Participants will do the exercise while keeping their blood pressure medication the same, and will be checked with ultrasound and blood pressure monitoring over about 6 months to a year.
ShatinAges 18–80 - NCT07666451Recruiting
Heart and neck artery ultrasound study in healthy children
This study uses ultrasound (sound waves) to take pictures of the heart and the main neck arteries in healthy children across Italy. It helps doctors learn what normal measurements look like for different ages.
Bologna, BolognaAges birth–18 years - NCT07670728Enrolling by invitation
Comparing two types of leg exercises for stroke patients with knee hyperextension
This trial tests whether open-chain (moving one part freely) or closed-chain (keeping foot on ground) exercises better improve knee hyperextension in stroke survivors. It may help you if you have leg weakness and walk with your knee locked back.
Karachi, SindhAges 7 months–1.2 years - NCT07669493Recruiting
Heart safety during chest radiation for cancer patients
This study looks at how chest radiation affects heart function and the immune system, and whether it is safe in people with lung, esophageal, breast, or thymus cancer who have not had chest radiation before.

This trial tests if metformin, a medicine commonly used for diabetes, can help improve heart function in people who have a mechanical heart pump (LVAD). You may be able to join if you are between 18 and 75, have a continuous-flow LVAD, and have a condition called insulin resistance (where your body doesn't use insulin well) but your blood sugar levels are well-controlled.
