In addition to AKI, other factors associated with an increased risk of CKD or ESRD include higher age [43, 49, 56], lower baseline renal function [36, 43, 44, 49, 57, 63, 64], diabetes [36, 56], hypertension [36, 49, 63, 64], chronic heart failure [49, 56], low serum albumin [49], proteinuria [64], liver failure [63], higher Charlson comorbidity index score [49, 63], and recurrent episodes of AKI [64]. Here, ALB is linked to acute kidney injury.
