Peer mentor support for atrial fibrillation
This study tests if having a peer mentor—someone who has been through similar health experiences—can help people with atrial fibrillation who have lower income or education levels. You would talk with a mentor and fill out surveys to see if this support improves your well-being.
Herlev, Capital RegionAges 18 years+ - NCT07499401Recruiting
Fluid response test in ICU patients with vein congestion
This study looks at how tiny blood vessels respond to extra fluids in ICU patients who have vein congestion. It helps doctors understand if giving more fluid is helpful or harmful for you.
Ancona, ItalyAges 18 years+ - NCT07499947Recruiting
Predicting low blood pressure during C-section
This trial looks at whether we can predict which pregnant women will have a sudden drop in blood pressure during a cesarean section. If you're a healthy pregnant woman with a full-term single baby, this study could help improve safety.
