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. [ Time Frame: Within 90 days following angiography ]

Death will be based on medical record and/or vital status registry documentation

Need for acute dialysis will be defined as the initiation of any modality of renal replacement (intermittent hemodialysis, peritoneal dialysis, continuous renal replacement therapy, or sustained low-efficiency dialysis)

Persistent decline in kidney function will be defined as an increase in serum creatinine of at least 50% from the baseline value collected pre-angiography to the measurement taken 90 days following the angiography.

Prevention of Serious Adverse Events Following Angiography
CSP #578 - Prevention of Serious Adverse Events Following Angiography (PRESERVE)
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 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. Using a 2 x 2 factorial design, patients will be randomized to receive: 1) either peri-procedural IV isotonic sodium bicarbonate or peri-procedural IV isotonic saline and 2) either oral NAC or oral placebo prior to and for 5 days following the angiographic procedure. The primary study endpoint is a composite outcome comprised of death, need for acute dialysis, or persistent decline in kidney function within 90 days following the index angiogram.
Interventional
Phase 3
Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Participant, Investigator
Primary Purpose: Prevention
  • Acute Renal Failure
  • Kidney Disease
  • Coronary Artery Disease
  • Drug: IV isotonic saline
    The investigators will administer 3 ml/kg of isotonic saline over 1 hour at an infusion rate of not less than 1 mL/kg per hour and not more than 3 mL/kg per hour prior to the angiographic procedure, 1-1.5ml/kg per hour during angiography, and 6 ml/kg of isotonic saline over 4 hours following the procedure at an infusion rate of not less than 1 mL/kg per hour and not more than 1.5 mL/kg per hour. Providers will retain discretion to administer larger volumes of isotonic saline (up to a maximum of 12 mL/kg) over durations of up to 12 hours pre and 12 hours post-procedure.
  • Drug: IV isotonic bicarbonate
    The investigators will administer 3 ml/kg of isotonic bicarbonate over 1 hour at an infusion rate of not less than 1 mL/kg per hour and not more than 3 mL/kg per hour prior to the angiographic procedure, 1-1.5ml/kg per hour during angiography, and 6 ml/kg of isotonic bicarbonate over 4 hours following the procedure at an infusion rate of not less than 1 mL/kg per hour and not more than 1.5 mL/kg per hour. Providers will retain discretion to administer larger volumes of isotonic bicarbonate (up to a maximum of 12 mL/kg) over durations of up to 12 hours pre and 12 hours post-procedure.
  • Drug: N-acetylcysteine
    NAC will be administered at a dose of 1200mg orally 1 hour prior to angiography, 1 hour following the procedure, and then twice daily for the next 4 days.
    Other Name: NAC
  • Drug: Placebo
    A placebo study drug capsule will be administered orally 1 hour prior to angiography, 1 hour following the procedure, and then twice daily for the next 4 days.
