Lunyera's publication shows racial differences in AKI incidence after PCI

Friday, January 22, 2021

Black patients had greater odds of developing acute kidney injury (AKI) after percutaneous coronary intervention (PCI) compared with White patients according to a new study published in the Journal of the American Society of Nephrology. The research team consists of 2 Duke GIM members, first author, Dr. Joseph Lunyera, and senior author, Dr. Clarissa Diamantidis.

The investigators examined the association of self-reported race and baseline eGFR with AKI incidence among patients who underwent PCI at Duke University Medical Center between January 1, 2003, and December 31, 2013. Of 9,422 patients in the analytic cohort, 9% developed AKI overall. Black race was associated with increased odds for incident AKI compared with white patients. This racial difference was seen even after accounting for socioeconomic, comorbid, and procedural characteristics.

The team concluded that future investigations should identify factors that predispose black individuals to this increased AKI risk after PCI.
