RenalGuard System and Contrast Media

Summary

The purpose of the present study is to assess the role of the RenalGuard System as compared to the optimal strategy (sodium bicarbonate infusion plus N-acetylcysteine (NAC)) in high and very-high risk patients to prevent contrast-induced acute kidney injury contrast induced acute kidney injury (CI-AKI). Consecutive patients with chronic kidney disease, referred to our institutions for coronary and/or peripheral procedures, will be randomly assigned to 1) prophylactic administration of sodium bicarbonate plus NAC (Systemic alone therapy group; n \> 133) and 2) RenalGuard System treatment (RenalGuard group; n \> 133). All enrolled patients must have an estimated glomerular filtration rate \<30 ml/min/1.73 m2 and/or a contrast nephropathy risk score ≥11). In all cases iodixanol (an iso-osmolar, non ionic contrast agent) will be administered. The primary end point is an increase of \>=0.3 mg/dL in the creatinine concentration 48 hours after the procedure. This study will give important answers on how to prevent CI-AKI in high and very-high risk patients undergoing contrast media exposure.
