Why the study?
Frailty assessment in transthyretin cardiac amyloidosis is poorly explored, and standardized tools for its evaluation in this setting are lacking.
Does frailty, assessed by the Clinical Frailty Scale or hand-grip strength, predict death and heart failure hospitalization in older patients with transthyretin cardiac amyloidosis?
Population
107 patients over 65 years with confirmed TTR-CA
Comparison
Frailty assessed by Clinical Frailty Scale (CFS) and hand-grip strength (HGS)
Design
Prospective observational cohort study
Follow-up
Median 16 months
Key result
A Clinical Frailty Scale score ≥5 independently predicted death and heart failure hospitalization in patients with transthyretin cardiac amyloidosis (HR 2.87; 95% CI 1.11-7.41; p=0.029).

Frailty, assessed by the Clinical Frailty Scale, is a significant independent predictor of mortality and heart failure hospitalization in older patients with transthyretin cardiac amyloidosis.
Passo et al. (2025) conducted a cohort in Transthyretin cardiac amyloidosis (TTR-CA) (n=107). Clinical Frailty Scale (CFS) ≥5 vs. CFS <5 was evaluated on Composite of death and heart failure hospitalization (HR 2.87, 95% CI 1.11-7.41, p=0.029). A Clinical Frailty Scale score ≥5 independently predicted death and heart failure hospitalization in patients with transthyretin cardiac amyloidosis (HR 2.87; 95% CI 1.11-7.41; p=0.029).
