Pre-Frailty Phenotype and Arterial Stiffness in Older Adults Free of Cardiovascular Diseases

Purpose: Arterial stiffness is a subclinical marker of cardiovascular disease (CVD). The pre-frailty phenotype is associated with a higher risk for CVD. This study investigated the association between the pre-frailty phenotype and arterial stiffness in community-dwelling older adults without diagnosed CVD. Methods: In total, 249 community-dwelling older adults aged 60-80 years were included in this cross-sectional study. The pre-frailty phenotype was defined by the standardized Fried criteria (muscle weakness; slow walking speed; low physical activity; unintentional weight loss; self-reported exhaustion). Participants with one or two standardized Fried criteria were classified as pre-frail and those with zero criteria as robust. Arterial stiffness was measured by aortic pulse wave velocity (aPWV). The data were analyzed using the generalized linear model. Results: From 249 participants (66.1 +/- 5.3 years; 79.5% females), 61.8% (n = 154) were pre-frail and 38.2% (n = 95) robust. Pre-frail older adults had a higher aPWV (beta = 0.19 m/s; p = 0.007) compared to their robust peers. Conclusions: The pre-frailty phenotype was associated with higher arterial stiffness in community-dwelling older adults aged 60-80 years. Pre-frail older adults may have a higher risk for CVD.
