Background: Renal dysfunction (RD) is common at admission for acute heart failure (AHF), but there is limited evidence focusing on older adults and considering the influence of physical function. We evaluated the prognostic significance of admission RD severity as a risk factor for adverse outcomes in older patients with AHF, while considering the potential modifying effect of physical function. Methods and Results: . Admission RD was stratified into 4 severity classes: mild RD (eGFR 45-59), moderate RD (eGFR 30-44), severe RD (eGFR 15-29), and kidney failure (eGFR
