IntraRenal HEmoDynamics to IntegraTE CA-AKI Risk and Monitor NephroprotectiIoN by ImpElla Support.

This study is examining whether monitoring blood flow inside the kidneys during a heart procedure called PCI (a procedure to open blocked heart arteries) can help predict and prevent kidney injury — a known complication that can occur after using contrast dye during the procedure. A heart-assist device called Impella may be used during the procedure. **You may be eligible if...** - You are between 18 and 90 years old - You are scheduled to have a PCI (coronary artery stenting procedure) in the near future or on the same day **You may NOT be eligible if...** - You have severe chronic kidney disease (very low kidney function) or are on dialysis - You have had a recent kidney injury in the past week - You are having a STEMI heart attack (a type of severe heart attack) within the last 24 hours, or have complications from a heart attack - You are in cardiogenic shock (heart not pumping enough to maintain blood pressure) - You had a cardiac arrest during this hospital stay and haven't fully recovered - You have a very low platelet count or active bleeding - You are pregnant or may be pregnant Talk to your doctor to see if this trial is right for you.
