Amino Acid-Based Metabolic Panel Provides Robust Prognostic Value Additive to B-Natriuretic Peptide and Traditional Risk Factors in Heart Failure

Table 3

Univariate and multivariable analysis for the HOP score and B-type natriuretic peptide (BNP) for discriminating patients at heart failure stage C from normal controls (initiation cohort).

The range of HOP score, value calculated by the combination of histidine, ornithine, and phenylalanine, is from −17.7 to 35.2 (on the basis of logistic regression model). Multivariable analysis adjusting for age, sex, left ventricular ejection fraction, diabetes mellitus, estimated glomerular filtration rate, and hypertension.
