Study of a new scoring balloon for leg artery blockages with heavy calcium buildup
This study tests a new balloon device that scores the artery walls to treat leg artery blockages with heavy calcium deposits. It aims to see if the device helps prepare the vessel safely and effectively before placing a stent.
Dalian, LiaoningAges 18–85 - NCT07397260Enrolling by invitation
Home blood pressure monitoring and feedback for hypertension
This trial tests whether sending your home blood pressure readings to your doctor and getting automatic feedback helps manage high blood pressure. You'll use a blood pressure monitor at home and share results through a patient portal.
Chicago, IllinoisAges 18–84 - NCT07396025Enrolling by invitation
Study of surgery for blocked carotid arteries
This trial looks at how well surgery and diagnostic tests work for people with a blocked carotid artery (the main artery in the neck that supplies blood to the brain). It may help if you have reduced blood flow to part of your brain and are able to understand instructions and communicate.
