Metabolomic Fingerprint of Heart Failure with Preserved Ejection Fraction
Fig 5
Heat map of metabolomic differences between HFrEF and controls.
Heat maps were generated with the concentrations of potential candidate metabolites with univariate analysis. Similar metabolites were arranged together for use in pathway analysis through intuitive pattern discovery. The heat map displays an increase in each metabolite in relative concentration as a red color and a decrease in a metabolite as a blue color. The metabolites are listed at the left side of each row, and the subjects are shown at the bottom of each column.
