Heart Failure with Preserved Ejection Fraction (HFpEF) is a severe medical condition. Concurrent pathologies linked with HFpEF create a complex scenario that contributes to structural and functional abnormalities in the heart and kidneys—the principal end organs affected by HFpEF. In this study, we assessed the effectiveness of a synergistic application of FTIR and Raman spectroscopy and multivariate/univariate statistical analyses to yield valuable pathophysiological insights in a rat model of heart failure. Peculiar biochemical differences were detected in the two organs demonstrating heightened sensitivity of these techniques towards the distinctive HFpEF phenotype.
