ALBUMIN BILIRUBIN SCORE ACROSS REDUCED AND PRESERVED EJECTION FRACTION PHENOTYPES IN CHRONIC HEART FAILURE

The albumin–bilirubin (ALBI) score combines two routinely available laboratory  measures.  A  between-phenotype  difference  may  identify  a  distinct  biochemical  profile, but does not establish liver fibrosis or independent prognostic value. Because  ALBI  is  calculated  from  albumin  and  bilirubin,  its  interpretation  depends on both the underlying measurements and their units. A comparison based  on  directly  traceable  numeric  inputs  is  preferable  to  reconstructing  ambiguous  spreadsheet entries. The present work therefore focused on an auditable completecase analysis rather than maximizing the nominal sample size.
