BLEEDING

This study looks at whether adding a blood thinner to standard antiplatelet therapy helps prevent strokes and blood clots in people who develop a new, temporary irregular heartbeat after coronary artery bypass surgery. About 3,200 adults who had bypass surgery and then experience…

This study looks at whether adding a drug called Wilate (a von Willebrand factor concentrate) to standard platelet transfusions can reduce bleeding and the need for more blood products in intensive care patients. About 120 adults who need platelets during or after surgery will be…

This study tests whether giving tranexamic acid (TXA) before and after major colorectal surgery can reduce bleeding and the need for blood transfusions. About 394 adults having inpatient colorectal surgery will either receive TXA or not. The trial also checks if TXA raises the ri…

This study is testing whether giving the blood thinner heparin before inserting a tube into the wrist artery can prevent a common complication: blockage of that artery. About 550 people undergoing a heart procedure through the wrist will be randomly assigned to receive heparin ei…

This study compares two approaches for low-risk patients with small blood clots in the lungs (isolated subsegmental pulmonary embolism). Half will receive standard blood-thinning medication (rivaroxaban), while the other half will get a placebo and be closely monitored. The goal …

This study tests whether giving blood transfusions quickly when hemoglobin drops can prevent delirium (sudden confusion) in patients 75 and older after hip fracture surgery. About 198 participants will be randomly assigned to either early transfusion or standard care. Researchers…

This study tests whether giving two common drugs, tranexamic acid and desmopressin, before surgery can reduce bleeding in patients with chronic kidney disease or acute kidney injury. About 100 adults having noncardiac surgery will be randomly assigned to receive one or both drugs…

This study compares two treatments for bleeding after heart surgery: FEIBA (a special clotting medicine) and fresh frozen plasma (standard care). About 140 adults having non-emergency heart surgery will be enrolled. The goal is to see if FEIBA reduces the need for blood transfusi…

This study looks at 128 people with advanced heart failure who have a HeartMate3 heart pump. All take warfarin to prevent clots, and half will also stop taking aspirin. The goal is to see if skipping aspirin lowers the risk of serious bleeding without raising the chance of danger…

This study compares cold-stored platelets to standard room-temperature platelets for controlling bleeding in adults after heart surgery. About 150 patients will be randomly assigned to receive one type. The goal is to see if cold storage is a safe and effective option, and to pla…

This study tests if a drug called tranexamic acid (TXA) can reduce blood loss during brain tumor surgery. About 102 adults having a craniotomy will receive either TXA or a placebo. Researchers will measure blood loss and check for bleeding-related complications within 30 days aft…

This study looks at whether giving iron through a vein (IV) can reduce bleeding symptoms in people with inherited bleeding disorders who also have low iron. About 40 participants will receive standard IV iron and be followed for 3 months to see if their bleeding, fatigue, and qua…

This study involves over 12,000 Chinese patients with coronary heart disease who take blood thinners. The goal is to find new biological markers that can better predict who is at risk for dangerous blood clots or major bleeding. Researchers will combine genetic, protein, and imag…

This study looks at 374 hip fracture patients who take blood thinners (DOACs). Doctors often delay surgery due to bleeding concerns, but waiting may cause other problems. The study compares early surgery (within 24 hours) to delayed surgery to see if early surgery increases the n…
