Purpose: The study aimed to assess frailty in adults with congenital heart disease (ACHD) and to compare muscle strength, functional capacity, activities of daily living (ADL), and cognition between frail and non-frail ACHD patients.
Materials and methods: A cross-sectional study design was used. Sixty people with ACHD aged between 18 and 45 years were included. Frailty was determined according to the Fried criteria. Peripheral muscle strength was assessed with a digital dynamometer, functional capacity with the 6-min walk test (6MWT), ADL with the Glittre ADL test, and cognition with the Montreal Cognitive Assessment (MoCA) test.
Results: Frailty was seen in 38.33% (frail = 23 and non-frail = 37) of the participants. In the frail patients, dominant knee extensor strength (p = 0.002), shoulder abductor strength (p = 0.005), 6MWT distance (p = 0.021), and MoCA score (p = 0.005) were significantly lower than those in the non-frail patients. Glittre ADL test (p = 0.002) was significantly higher in the frail patients.
Conclusions: Muscle strength, functional capacity, ADL, functional mobility, and cognition were lower in the frail participants with ACHD. Early assessment of frailty in ACHD and planning individualized exercise training programs for frail individuals may be a strategy to reduce the impact of frailty on adverse clinical outcomes.
Keywords: Congenital heart disease; activities of daily living; cognition; frailty; functional capacity; muscle strength.
We found that muscle strength, functional capacity, ADL, functional mobility, physical activity, and cognition were lower in the frail ACHD patients than in the non-frail ones.Early assessment of frailty in individuals with ACHD is important for determining health status.Planning individualized exercise training programs for individuals with ACHD may be a strategy to reduce the impact of frailty on adverse clinical outcomes.
