Predicting Contrast-Associated AKI for Intravenous Contrast Exposure and Non-coronary Angiography Procedures: A Review of the Literature

Introduction: Although cases of contrast associated AKI (CA-AKI) have been reported over the years
and several studies exist on the subject, there has been little success in terms of developing a
generally acceptable prediction model for this preventable disease. Majority of work done has been on
patients under going coronary angiography and are not generalisable due to heterogeneity of patients
and procedure related factors.
The aim of this chapter is to review the epidemiology and prediction models of CA-AKI in patients
receiving intravenous contrast for non-coronary angiography procedures.
Conclusion: Although non-coronary procedures are more routinely performed in most institutions,
very few prediction models exist for patients undergoing these procedures and this limits preventive
efforts. Clearly, prediction models developed for PCI should not be adopted for non-coronary
angiography procedures.
