Association between cardiac, renal, and hepatic biomarkers and outcomes in patients with acute heart failure

ABSTRACTObjectives: Myocardial injury, worsening renal function, and hepatic impairment are independent risk factors for poor patient acute heart failure (AHF) outcomes. Biomarkers of organ damage may be useful in identifying patients at risk for poor outcomes. The objective of this analysis was to assess the relationship between abnormal AHF biomarkers and outcomes in AHF patients.Methods: AHF admissions (N = 104,794) data from the Cerner Health Facts® inpatient database were analyzed retrospectively. Multivariate predictive models determined the impact of biomarkers on mortality, readmission, length of stay (LOS), and cost from index admission through 180 days post discharge. Thirty and 60 day time windows are reported but 180 day results were consistent with 60 day outcomes. Biomarkers evaluated were aspartate transaminase (AST), estimated glomerular filtration rate (eGFR), high sensitivity cardiac troponin, bilirubin, alanine transaminase (ALT), sodium, high sensitivity C-reactive protein (hs-CRP), ur...
