Relationship between Worry, and Anger Rumination with Cardiovascular Disease Severity: Social Loneliness as a Moderator.

Background Biological and psychological factors contribute to cardiovascular disease (CVD). This study aimed to test the moderating effect of social loneliness in the relationship between worry and anger rumination, and CVD severity. Methods A total of 327 patients with CVD (138 women, 189 men) participated in this study. The Penn State Worry Questionnaire (PSWQ), Anger Rumination Scale (ARS), Social Loneliness Scale (SLS), and Gensini score as an indicator of CVD severity were used to collect data. Data were analyzed using Pearson correlation and stepwise regression. Results The results of this study showed a significant positive correlation between worry (54.44 ± 12.31, r = 0.59, P 0.05). Conclusion Based on the findings of this research, it can be concluded that along with biological factors, attention to the role of psychological factors of worry, anger rumination, and loneliness in preventive and therapeutic interventions related to CVD is a special necessity.
