Frailty (9.5% frail, 59.7% pre-frail) was independently associated with structural and functional markers of diastolic dysfunction, particularly left atrial enlargement and NT-proBNP elevation.

Is frailty associated with echocardiographic indices of diastolic function and cardiac biomarkers in community-dwelling older adults?
Frailty in older adults is independently associated with structural and functional markers of diastolic dysfunction, supporting the integration of frailty assessment into cardiovascular risk evaluation.
Background: Frailty in older adults is linked to adverse cardiovascular outcomes, but its relationship with echocardiographic markers of diastolic function remains unclear. We examined associations between frailty measures and indices of diastolic function in community-dwelling older adults. Methods: This cross-sectional study included 537 adults aged ≥65 years from a multidisciplinary outpatient clinic. Frailty was assessed using the Fried phenotype, Clinical Frailty Scale (CFS), gait speed, and handgrip strength. Associations with diastolic indices were analyzed using multivariable regression with sequential adjustment. Sensitivity analysis was performed via matching. Results: According to the Fried phenotype, 30.8% of participants were robust, 59.7% pre-frail, and 9.5% frail. Indexed left atrial dimension (LAi) was consistently higher in frail individuals. Frailty was also associated with higher odds of elevated right ventricular systolic pressure (>35 mmHg) in unadjusted analyses. Using the CFS, individuals with a score higher than 3 had significantly higher NT-proBNP levels compared to those with a score of 1–2. Higher gait speed and handgrip strength were associated with more favorable cardiac structure, including smaller left heart chamber sizes, and lower natriuretic peptide levels. Conclusions: Frailty was independently associated with structural and functional markers of diastolic dysfunction in older adults, particularly left atrial enlargement (as captured in Fried) and NT-proBNP elevation (as captured in CFS), supporting the integration of frailty assessment into cardiovascular risk evaluation.
Anagnostou et al. (Mon,) conducted a cross-sectional in Frailty and diastolic dysfunction (n=537). Frailty vs. Robust status (no frailty) was evaluated on Echocardiographic indices of diastolic function. Frailty (9.5% frail, 59.7% pre-frail) was independently associated with structural and functional markers of diastolic dysfunction, particularly left atrial enlargement and NT-proBNP elevation.
