Why the study?
The association of arterial stiffness with HFpEF was derived from few studies using outdated diagnostic criteria, so this study evaluated its association with the HFA-PEFF score.
Is arterial stiffness measured by augmentation index associated with the likelihood of HFpEF in an elderly population?
Is arterial stiffness measured by augmentation index associated with the likelihood of HFpEF in an elderly population?
Higher arterial stiffness is associated with adverse left ventricular remodeling and a significantly higher likelihood of HFpEF in elderly males, but not in females.

AIx-associated HFpEF likelihood in elderly men is hypothesis-generating; leaves open causality and clinical utility.
Arterial stiffness has been suspected as a cause of left ventricular diastolic dysfunction and may thereby contribute to the development of heart failure with preserved ejection fraction (HFpEF). However, this association is derived from a small number of studies and application of outdated criteria to diagnose HFpEF. This study aimed to investigate the association of arterial stiffness measured by the augmentation index (AIx) and criteria for diagnosing HFpEF according to the recommended HFA-PEFF score. Our analysis based on data from the first follow-up of the CARdiovascular Disease, Living and Ageing in Halle study. The current analysis included participants with available information about comorbidities and risk factors for HFpEF, parameters for calculation of the HFA-PEFF and noninvasive AIx estimated by applanation tonometry. The association of AIx and HFA-PEFF was investigated through descriptive and inductive statistics. A total of 767 participants were included in the analysis. AIx was associated with E/e', left ventricular wall thickness (LVWT), relative wall thickness, left ventricular mass index (LVMI) and NT-proBNP but not with e' or left atrial volume index. However, after adjustment for confounders, only LVMI and LVWT remained associated with AIx. Males with a high AIx had a 3.2-fold higher likelihood of HFpEF than those with a low AIx. In contrast, that association was not present in females. In summary, AIx is associated with the morphological domain of the HFA-PEFF score represented by LVMI and LVWT. Higher values of AIx are associated with a higher likelihood for HFpEF in elderly males but not in females.
