Glomerular filtration rate was estimated by the Chronic Kidney Disease Epidemiology Collaboration equation (eGFR), and patients were grouped by eGFR: eGFR group I, \u226590 mL\/min\/1.73 m2; eGFR group II, 60\u201389 mL\/min\/1.73 m2; and eGFR group III, \u226459 mL\/min\/1.73 m2. Multivariate linear regression models were developed to evaluate the associations between eGFR groups and hormones. A total of 149 patients participated in the study. Median age was 69 [interquartile range (IQR): 64\u201373] and 26% were female; LVEF was 33% (IQR: 27\u201339), 78% were in functional class II\u2013III, median eGFR was 74 (54\u201389) mL\/min\/1.73 m2, and median N-terminal pro-brain natriuretic peptide was 1303 pg\/mL (IQR: 441\u20132740). RD was associated with increased aldosterone, parathyroid hormone (PTH), and copeptin concentrations (P &amp;lt; 0.05 for all) after adjustment for traditional confounders and medical treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>RD is associated with increased concentrations of aldosterone, PTH, and copeptin in systolic HF outpatients.
