The intravascular administration of iodinated contrast media for diagnostic imaging is a common cause of acute kidney injury (AKI) and a leading cause of iatrogenic renal disease. Contrast-induced AKI is associated with serious adverse outcomes including death, need for dialysis, prolonged hospitalization, and acceleration in the rate of progression of underlying chronic kidney disease. The benefit of IV isotonic bicarbonate compared to IV isotonic saline and of N-acetylcysteine for the prevention of contrast-induced AKI and associated adverse outcomes remains unclear. The purpose of this trial is to compare the effectiveness of IV isotonic sodium bicarbonate with IV isotonic sodium chloride and oral NAC with placebo for the prevention of serious adverse outcomes in 7,680 high-risk patients scheduled to undergo coronary or non-coronary angiography.
The purpose of this research study is to compare the effectiveness of intravenous isotonic sodium bicarbonate with intravenous isotonic sodium chloride and oral N-acetylcysteine with oral placebo for the prevention of serious adverse outcomes following angiographic procedures in high-risk patients.
The primary outcome will be a composite of serious, adverse, patient-centered events, including death, need for acute dialysis, or persistent decline in kidney function.
Planned elective or urgent coronary or non-coronary angiography with iodinated contrast media in which it is anticipated that there will be an interval of 3 hours between the identification of the indication for angiography and the time of the planned procedure.
