Protecting the heart during breast cancer radiation
This trial tests whether a special breathing technique (called Active Breathing Coordinator) can help keep radiation away from the heart while treating breast cancer with radiation therapy. If you can hold your breath briefly during treatment, this might lower the risk of heart damage.
Pavia, LombardyAges 18 years+ - NCT07300163Recruiting
FeetSee: Thermal images for diabetes foot health
This study collects thermal (heat) images of the feet of people with diabetes who have had a healed foot ulcer. The goal is to see if these images can help prevent future foot problems.
VilniusAges 18 years+ - NCT07301034RecruitingPhase 3
Ziltivekimab for plaque after a heart attack
This study tests a drug called ziltivekimab to see if it can reduce fatty plaque buildup in heart arteries after a heart attack. It's for people who had a heart attack treated with a stent and have mild blockages in other arteries.
ViennaAges 18 years+ - NCT07301190Recruiting
Study of PFLotus for persistent atrial fibrillation
This study tests a new device called PFLotus for people with persistent atrial fibrillation (AF), a type of irregular heartbeat. The goal is to see if it can help restore a normal heart rhythm in people who haven't gotten better with medicine.
ChengduAges 18–75 - NCT07301489Recruiting
Heart study for lung screening participants
This trial adds a heart health check to an existing lung cancer screening study. It looks at old chest CT scans to assess heart disease risk and asks you to return for a follow-up visit one year later.
Lørenskog, AkershusAges 60–79 - NCT07301892Recruiting
AI help for rheumatoid arthritis diagnosis
This trial tests whether artificial intelligence (AI) can improve how doctors spot complications in people newly diagnosed with rheumatoid arthritis (RA), a condition that causes joint pain and swelling. The goal is to see if AI can make diagnosis faster and more accurate in real-world hospital settings.
Beijing, Beijing MunicipalityAges Any age - NCT07302009Recruiting
Cooling treatment for brain hemorrhage patients
This trial tests a bladder-based cooling device to see if it can safely control fever in patients with a new brain hemorrhage. It may help prevent further brain injury and improve recovery.
Nanchang, JiangxiAges 18–85 - NCT07302620Recruiting
Can heparin affect argatroban lab results?
This study looks at whether the presence of heparin (a common blood thinner) can interfere with the lab test used to measure another blood thinner called argatroban. If you are already having your heparin level checked, this study uses the same blood sample to see if heparin affects argatroban results.
