Health literacy, health-related quality of life, and atrial fbrillation.

Atrial fbrillation (AF) is a chronic heart rhythm disorder associated with significant adverse outcomes. Health-related quality of life (HRQoL) is an established metric of health status in individuals with AF, and health literacy is highly relevant to how individuals experience HRQoL. We conducted a pilot investigation to examine the association of health literacy and health related quality of life (HRQoL) in a limited-sized cohort of individuals with AF, all of whom had AF and were ≥60 years old. We used the Short-Test of Functional Health Literacy in Adults to categorize participants by health literacy status. We used the SF-36 to examine HRQoL in eight subscales and two composite scores, and related health literacy to HRQoL. In our cohort of 40 participants with AF (45% female, age 77.9 ± 8.0 years), 62.5% had inadequate health literacy. However, we did not identify a significant association between health literacy and HRQoL. We expect our limited-sized sample is a chief limitation for why we did not see an association between health literacy and HRQoL in this convenience cohort. Further studies examining health literacy and its impact on patient-centered outcomes in AF are essential.
