Body composition test in heart attack patients
This trial looks at how a simple, painless test called bioelectrical impedance analysis can measure your body's water, fat, and muscle. It may help doctors understand how these factors affect recovery from a heart attack or unstable angina.
Buenos Aires, Buenos AiresAges 18 years+ - NCT06561932Recruiting
Leadless pacemaker for heart failure resynchronization
This trial tests a completely leadless pacemaker (WiSE® CRT) for heart failure patients who need cardiac resynchronization therapy (CRT). It aims to avoid the long-term risks of traditional wires (leads) in the heart.
Birtinya, QueenslandAges 22 years+ - NCT06562478Recruiting

Porto Alegre, Rio Grande do SulAges 18 years+ - NCT06562582RecruitingPhase 4
Starting heart drugs after a STEMI heart attack
This study tests whether starting a beta blocker and an SGLT2 inhibitor right after a heart attack can help preserve heart function. It is for STEMI patients who have not yet been treated with these medicines.
GothenburgAges 18 years+ - NCT06563206Recruiting
Exergame and robotic therapy for stroke recovery
This study tests whether playing video games that involve movement (exergaming) or using a robotic arm device can help improve arm function and reduce inflammation after a stroke. It may be a good fit if you are ready to start therapy and can sit up and watch a screen.
Makassar, South SulawesiAges Any age - NCT06563817RecruitingPhase 2
Testing rapamycin for fluid buildup after a brain bleed
This trial tests whether the drug rapamycin can help people whose brain ventricles stay enlarged after a bleed, causing walking, memory, or bladder issues. If you qualify, you may receive rapamycin to see if it improves your symptoms and reduces fluid buildup.
Beijing, Beijing MunicipalityAges 18–70 - NCT06564675Recruiting
Using EEG brain waves to predict recovery after cardiac arrest
This trial uses a special EEG device (Brainstatus) to measure brain activity in people who are still unconscious after a cardiac arrest. The goal is to see if certain brain waves can predict a good recovery.
HelsinkiAges 18–110 - NCT06564831Recruiting
Placental graft for diabetic foot ulcers
This study tests whether a special placental tissue graft placed on a diabetic foot ulcer helps it heal faster than standard wound care alone. It is for people with a diabetic foot ulcer that has not healed after 4 weeks of usual care.
Clinton Township, MichiganAges 18 years+ - NCT06566105Recruiting
Fatty liver study for blood donors with weight concerns
This study collects blood samples from donors with excess weight or related health issues to better understand fatty liver disease. If you are a blood donor between 40 and 65, and have overweight, high blood sugar, abnormal cholesterol, or high blood pressure, you may be able to help.
Milan, MilanoAges 40–60 - NCT06566196Recruiting
Heart exercise testing for congenital heart disease
This study tests how well your heart pumps during exercise while you are undergoing a heart catheter procedure. It may help doctors better understand your heart function and guide your treatment.
Rochester, MinnesotaAges 18 years+ - NCT06566911Recruiting
Voice analysis for monitoring heart failure
This trial tests if recording your voice can help doctors monitor heart failure that has suddenly gotten worse. You participate by giving voice samples, which may help find new ways to track your condition.
Rochester, MinnesotaAges 18 years+ - NCT06566976Recruiting
Exercise before and after stent for PAD
This study tests a program of exercise before and after a stent procedure for people with peripheral artery disease who have leg pain while walking. The goal is to see if this helps improve walking ability and recovery.
Palo Alto, CaliforniaAges 18 years+ - NCT06567249Recruiting
Cooling the heart during a heart attack procedure
This study tests whether cooling the heart with a cold liquid during a procedure (angioplasty) can help reduce damage after a heart attack. It may be an option for people who arrive at the hospital quickly after a heart attack.
TomskAges 18–90 - NCT06567626Recruiting
Decision aid for heart artery treatment choices
This study is testing a new tool to help patients and doctors decide together on the best procedure (like stents or bypass surgery) for blocked heart arteries. It aims to make the decision process clearer and more personalized.
LeicesterAges Any age - NCT06567418Recruiting
Early use of PCSK9i in Chinese heart attack patients
This study looks back at medical records of Chinese patients who had a heart attack or unstable angina. It compares outcomes for those who started a newer cholesterol-lowering shot (Alirocumab, brand name Praluent) plus a statin while in the hospital, versus those who only took a statin pill. The goal is to see if starting the shot early helps improve heart health.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06567938Recruiting
Heart artery procedure study for people with kidney disease
This trial uses a special ultrasound camera inside the heart's arteries to guide stent placement for people with chronic kidney disease. The goal is to see if this approach improves outcomes compared to standard methods.
Xi'an, ShaanxiAges 18 years+ - NCT06567795Recruiting
Monitoring heart risk with a wearable sensor in diabetes
This trial tests a wearable chest sensor (called HEMOTAG) to monitor heart events in people with long-standing Type 2 diabetes who also have heart disease or specific diabetes-related complications. The sensor is worn at home for short periods to catch early signs of heart trouble, aiming to improve personalized care.
West Palm Beach, FloridaAges 40 years+ - NCT06567912Recruiting
TEE training with AI assessment for emergency doctors
This study is creating a training program and an AI-powered tool to help emergency physicians learn how to use TEE, a type of ultrasound that looks at the heart. It's for doctors who want to improve their skills in this area.
TaipeiAges 18–99 - NCT06568159Recruiting
Sleep apnea treatment in heart patients
This study looks at how well people with heart disease or high heart risk follow their sleep apnea treatment, comparing a mouth device (MAD) to a CPAP machine. It aims to find which treatment works better for daily use.
