This article, Contrast-Induced Kidney Injury Risk Low in Chronic Kidney Disease, May Be Preventable, discusses how the risk of death and adverse kidney outcomes from contrast-associated acute kidney injury in patients with chronic kidney disease may be lower than previously thought.
Through a trial that was performed, they found that in almost 4500 patients, there was a low increased risk for death, the need for dialysis, or persistent kidney impairment at 90 days. They also found that AKI did not mediate the relationship between baseline kidney function and the development of those serious adverse outcomes.
The main key they are looking at with this study is that the incidence of clinically significant CA-AKI in those patients with CKD who are undergoing non-emergent angiography and who receive periprocedural isotonic intravenous fluid is very low.
The trial showed that CA-AKI was not found to mediate the association between baseline kidney function and the primary outcome. The pre-angiography eGFR was significantly associated with the development of CA-AKI. Pre-angiography eGFR and CA-AKI were both significantly associated with the primary outcome.
Providers should typically perform clinically indicated angiographic procedures in these patients using appropriate preventive care without undue excessive concern for causing AKI. The risk of serious complications following the intra-arterial administration of contrast media is very low, so angiographies should not be withheld in patients with impaired renal function. However, even though the risk is low, there is still a subgroup of patients that may still benefit from interventions aimed at protecting the kidneys during angiography.
Previous research had shown a substantially increased relative risk for serious outcomes with CA-AKI, including mortality, stroke, myocardial infarction and/or end-stage kidney disease.
