-
Adenosine given before primary PCI to reduce no-reflow in STEMI patients.
See if giving intracoronary adenosine before primary PCI lowers the chance of slow flow/no-reflow in adults with STEMI.
-
Brain blood flow changes after successful clot removal in acute ischemic stroke
This study will use a special MRI blood-oxygenation breathing test to see if it can detect patients with acute ischemic stroke who do not improve after successful clot removal.
-
Administering adrenaline in STEMI patients during PCI to prevent no reflow
This study tests if giving adrenaline during heart procedures can help STEMI patients avoid complications with blood flow without causing heart rhythm problems.
-
Evaluating Nicorandil to Prevent Blood Flow Issues During Heart Procedures
This study is testing if a medication called nicorandil can help people with high-risk heart plaque maintain better blood flow during heart procedures like stent placement.
