Abstract
BACKGROUND: Health-related quality of life (HRQoL) is worse in patients with atrial fibrillation (AF) compared with other populations. Factors affecting HRQoL in patients with AF are not fully clarified. Illness perceptions are important determinants of disease management and may affect HRQoL. OBJECTIVE: The aims of this study were to describe illness perceptions and HRQoL in women and men with AF and to explore the relationship between illness perceptions and HRQoL in patients with AF. METHODS: This cross-sectional study included 167 patients with AF. Patients completed the Revised Illness Perception Questionnaire and HRQoL questionnaires: Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmias, the three-level version of the EuroQol 5-dimensional questionnaire, and EuroQol visual analog scale. Subscales of the Revised Illness Perception Questionnaire significant in correlation analysis with the Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmias HRQoL total scale were included in a multiple linear regression model. RESULTS: Mean age was 68.7 ± 10.4 years, and 31.1% were women. Women reported lower personal control ( P = .039) and worse HRQoL measured with the Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmias physical subscale ( P = .047) and the EuroQol visual analog scale ( P = .044) compared with men. Illness identity ( P < .001), consequences ( P = .031), emotional representation ( P = .014), and timeline cyclical ( P = .022) were related to and adversely affected HRQoL. CONCLUSIONS: This study found a relationship between illness perceptions and HRQoL. Some subscales of illness perceptions negatively affected HRQoL in patients with AF, which indicates that efforts to change illness perceptions may be helpful in improving HRQoL. Patients should be given the opportunity to talk about the disease, their symptoms, their emotions, and the consequences of the disease to enable increased HRQoL. A challenge for healthcare will be to design support for each patient based on his/her illness perceptions.
