Generalizability of the Spectrum of Kidney Risk in the FINEARTS-HF Trial to U.S. Adults With Heart Failure

Albuminuria (urine albumin-to-creatinine ratio UACR ≥30 mg/g) and estimated glomerular filtration rate (eGFR) constitute the basis of contemporary kidney disease staging, and are independently associated with HF onset and progression. 1 ME Grams Coresh J Matsushita K et al.

However, because UACR has been infrequently assessed in HF outcomes trials, generalizability of trial-level kidney risk to real-world HF populations remains uncertain.
