Abstract

Contrast-induced acute kidney injury (CI-AKI) is the acute impairment of renal function further to the intravascular administration of iodinated contrast media, and occurs most frequently after coronary angiography, percutaneous coronary intervention, and contrast-enhanced computed tomography. CI-AKI has been associated with the development of acute renal failure, worsening of chronic kidney disease, requirement for dialysis, prolonged hospital stay, and higher mortality rates and health care costs. Recently, a number of studies suggested that contrast media exposure might not be the causative agent in the occurrence of acute kidney injury, particularly in stable patients who receive small to moderate amounts of contrast media. However, those who undergo coronary angiography and intervention are indeed subject to an increased hazard of CI-AKI, in view of a more significant contrast media exposure as well as the presence of concomitant risk factors. Solid randomized clinical trials are therefore required to identify preventative strategies to reduce the risk of CI-AKI and its complications in these patients. © 2017 Canadian Cardiovascular Society
