Activities of daily living at different levels of renal function in elderly hospitalized heart failure patients

Background Renal function (RF) and activities of daily living (ADL) are risk factors for heart failure (HF) patients. Aims We evaluated differences in motor and cognitive ADL in relation to RF in elderly hospitalized HF patients. Methods Participants were selected from 414 consecutive hospitalized HF patients based on certain criteria. We investigated patient characteristics including Functional Independence Measure (FIM) and estimated glomerular filtration rate (eGFR). Subjects were divided into three groups by RF level and analyzed with one-way ANOVA and Chi-square tests and two-way ANCOVA and multiple comparison tests. Results Of the 414 patients, 165 met the inclusion criteria (high RF: 41, moderate RF: 84, low RF: 40). There were significant differences between the three groups in age, eGFR, hemoglobin level, mobility, cognitive function, and length of hospital stay ( p
