Short vs. 12-month prasugrel and aspirin after a heart attack with a stent
This trial compares taking a shorter course of prasugrel (a blood thinner) plus aspirin after a heart attack versus the standard 12-month course. It aims to see if a shorter duration is just as effective and safer for people who got a specific type of stent (everolimus-eluting).

Virtual reality therapy for left-side neglect after stroke
This study tests whether immersive virtual reality with added sensations (like sounds and touch) can help people who have trouble noticing their left side after a right-sided stroke. If you had a first right-sided stroke within the past 3 months and have left neglect, this might help you regain function.

Finding the exact spot of a heart extra wire
This study looks at a new way to figure out exactly where a tiny extra electrical wire in your heart (called a septal accessory pathway) is located, to help guide the procedure that fixes it. It might help make the treatment more precise and safe.

This study tests whether a program in schools can help prevent rheumatic heart disease in children. If your child is between 5 and 16 years old and attends a participating school, they may be able to join.
KathmanduAges 5–16 - NCT06721234Recruiting
Vein thickness and inflammation in Behcet disease
This study looks at how the thickness of the femoral vein wall and certain markers of inflammation relate to Behcet disease. It may help doctors better understand and monitor the condition.
SohagAges 19–80 - NCT06721754Recruiting
Negative pressure therapy for diabetic foot ulcers
This study tests if a vacuum-like wound dressing (negative pressure wound therapy) helps heal diabetic foot ulcers after surgery. It may be a good fit if you have a foot ulcer needing surgery and are able to walk.
Oslo, NordbyhagenAges 18 years+ - NCT06722066Recruiting
TAVR and heart valve calcium study
This study looks at how calcium buildup in the aortic valve affects long-term results after a TAVR procedure (a minimally invasive heart valve replacement). It may help doctors understand which patients do better over time.
SeoulAges 19 years+ - NCT06722196RecruitingPhase 3
Amiodarone patch to prevent afib after heart surgery
