Do individual characteristics (such as perceived stress and physical activity) predict health-related quality of life and treatment satisfaction in patients with atrial fibrillation?
Individual characteristics, particularly perceived stress and household physical activity, are important predictors of health-related quality of life and treatment satisfaction in patients with atrial fibrillation.
BACKGROUND: Patients with atrial fibrillation (AF) have significantly lower health-related quality of life (HRQoL) compared to the general population and patients with other heart diseases. The research emphasis on the influence of AF symptoms on HRQoL overshadows the role of individual characteristics. To address this gap, this study's purpose was to test an incremental predictive model for AF-related HRQoL following an adapted HRQoL conceptual model that incorporates both symptoms and individual characteristics. METHODS: Patients attending an AF specialty clinic were invited to complete an online survey. Hierarchical regression analyses were conducted to examine whether individual characteristics (overall mental health, perceived stress, sex, age, AF knowledge, household and recreational physical activity) incremented prediction of HRQoL and AF treatment satisfaction beyond AF symptom recency and overall health. RESULTS: Of 196 participants (mean age 65.3 years), 63% were male and 90% were Caucasian. Most reported 'excellent' or 'good' overall and mental health, had high overall AF knowledge scores, had low perceived stress scores, and had high household and recreation physical activity. The mean overall AF Effect On Quality-Of-Life Questionnaire (AFEQT) and AF treatment satisfaction scores were 70.62 and 73.84, respectively. Recency of AF symptoms and overall health accounted for 29.6% of the variance in overall HRQoL and 20.2% of the variance in AF treatment satisfaction. Individual characteristics explained an additional 13.6% of the variance in overall HRQoL and 7.6% of the variance in AF treatment satisfaction. Perceived stress and household physical activity were the largest contributors to overall HRQoL, whereas age and AF knowledge made significant contributions to AF treatment satisfaction. CONCLUSIONS: Along with AF symptoms and overall health, individual characteristics are important predictors of HRQoL and AF treatment satisfaction in AF patients. In particular, perceived stress and household physical activity could further be targeted as potential areas to improve HRQoL.
Rush et al. (Thu,) conducted a cross-sectional in Atrial fibrillation (n=196). Individual characteristics (mental health, stress, sex, age, knowledge, physical activity) was evaluated on Variance in overall health-related quality of life (HRQoL) and AF treatment satisfaction. Individual characteristics, particularly perceived stress and household physical activity, explained an additional 13.6% of the variance in overall HRQoL beyond AF symptoms and overall health.
