Gender, lifestyles, illness perception and stress in stable atrial fibrillation

The study is aimed at investigating if perceived stress in Stable Atrial Fibrillation (AF) has any gender-associated feature and relationships with lifestyle indicators and education level, and which relationship self efficacy, anxiety and depression and illness perception have, if any.

88 consecutive patients referred for stable AF are studied by Psychological Stress Measure (PSM) test, Illness Perception Questionnaire (IPQ-R), Generalized Self-Efficacy scale (GSE) and Hospital Anxiety and Depression Scale (HADS). Mediterranean diet, physical activity increase and smoking withdrawal counseling were provided.

AF patients have higher PSM associated with gender (women), older age, anxiety and depression. Higher GSE, greater Adherence to Mediterranean Diet profile and coffee habits (greater coffee users) are associated with a reduced hazard of perceived stress. By multiple linear regression, PSM is explained by Anxiety and IPQr (statistically significant are emotional representation and illness coherence subscales), which account for 92.2% of the variance (p<0.0001).

Our results outline that psychological stress is greater in women in comparison with men. Illness perceptions are important in the context of perceived stress in AF. This effect appears to be modulated by greater self-efficacy and by Adherence to Mediterranean Diet profile, that when higher, are associated with a reduced hazard of perceived stress. We suggest that therapeutic interventions on illness perceptions can be warranted in order to achieve a lower psychological distress in AF patients.
