Ischemia reperfusion injury

This phase 2 trial tests whether a combined antioxidant therapy—ascorbate, N-acetylcysteine, and deferoxamine—can reduce heart muscle damage when given before and during angioplasty for a first anterior ST-elevation heart attack. Adults eligible for primary PCI will be randomly a…

This trial tests whether giving empagliflozin before or after a procedure to open a blocked heart artery (primary PCI) reduces heart muscle injury during a heart attack. Adults aged 18-75 of South Asian origin having their first heart attack will be randomly assigned to receive e…

This study compares two methods of preserving livers from deceased donors before transplant: a machine that pumps oxygenated cold fluid through the liver (hypothermic machine perfusion) versus the standard ice-cooled storage. Forty adult liver transplant patients will be randomly…

This early-stage study tests the safety of a drug called pegcetacoplan (Empaveli) in 20 adults who have had a stroke from a large clot and already had a procedure to remove it. The drug aims to reduce swelling and inflammation that can occur when blood flow returns. Participants …

This early study tests a special cap that shines near-infrared light on the heads of infants who have had a cardiac arrest in the hospital. The light is meant to reduce brain injury caused when blood flow returns. The trial will include 30 infants with heart disease and will chec…

This study tests whether cooling the head (using a special cap) during emergency stroke treatment can reduce the amount of brain tissue that dies. About 182 adults having a major stroke and undergoing a clot-removal procedure will be randomly assigned to receive either standard c…

This study tests Shenkangling, a traditional Chinese herbal tonic, in 100 adults who experience kidney injury during surgery. The goal is to see if it helps kidneys recover and is safe. Participants take the herb twice daily, and researchers measure urine and blood markers of kid…

This early-phase study tests whether taking vitamin B6 for up to 31 days can reduce the sharp rise in blood pressure that happens during exercise after a temporary lack of blood flow (like a leg injury). Researchers will measure blood pressure, heart rate, nerve activity, and wal…

This observational study tests whether a new device, the SpectroCor Tissue Oxygenation Monitor, can accurately track oxygen levels in the heart muscle of children undergoing open-heart surgery. The device uses a sensor placed on the heart to measure oxygen availability during key…

This study looks at whether inflammation levels differ on either side of a blood clot in the brain during a stroke treatment called mechanical thrombectomy. Researchers will compare blood samples taken from before and after the clot to see if the difference is linked to how well …

This study investigates whether examining liver tissue during a cold preservation technique called hypothermic oxygenated machine perfusion can help predict how well the organ will work after transplant. Researchers will compare biopsies taken before and after perfusion and analy…

This study looks at a simple idea: during a liver transplant, the first blood that flows into the new liver may contain harmful substances. By discarding that blood before connecting the liver to the patient's circulation, doctors hope to reduce heart, kidney, and liver problems.…
