Abstract

Opinion statement: Contrast-induced acute kidney injury (AKI) is an important complication associated with coronary angiography, percutaneous coronary intervention, and computed tomography studies. The increasing utilization of contrast agents for imaging makes the importance of this complication even greater. Patients can be risk stratified for the risk of contrast-induced AKI by several clinical factors including hypotension, renal function, age, advanced heart failure, anemia, and diabetes mellitus. Contrast volume is also an important and modifiable risk factor for AKI. For the prevention of contrast-induced AKI, multiple approaches have been tried. The most effective prevention strategy is hydration. Normal saline has been the standard, but other options such as sodium bicarbonate may be a reasonable alternative. Further studies will be required to clarify the best preventive strategies.
