Incidence of contrast-induced acute kidney injury associated with diagnostic or interventional coronary angiography.

Background: Contrast-induced acute kidney injury (CI-AKI) represents an important cause of hospital-acquired AKI. The aim of this study was to evaluate the incidence of CI-AKI after coronary angiography (CA) or percutaneous coronary intervention (PCI) and the role of patient-/procedure-related risk factors.

Methods: For 11 months, patients undergoing CA or PCI were prospectively evaluated for CI-AKI, and factors possibly affecting CI-AKI were analyzed.

[Continuous renal replacement therapies (CRRT) will remain the most widely adopted dialysis modality in the critically ill].

In the last 10-15 years, user-friendly continuous renal replacement therapy (CRRT) machines have played a major role in increasing the popularity of these techniques in intensive care settings. At present it is not clear which modality of renal replacement therapy (RRT) is optimal for critically ill patients with acute kidney injury (AKI). The choice between different modalities should therefore not be based on unproven ''outcome'' advantages but on evaluation of the clinical picture and logistical circumstances.
