Background. Adjustment to heart disease, as an stressful experience, is a difficult process and involves the patient in serious issues.
Method. A total of 327 people with coronary artery disease (138 women, 189 men) participated in this descriptive correlational study. Participants were asked to complete the Penn State Worry Questionnaire (PSWQ), Anger Rumination Scale (ARS), Social Loneliness Scale (SLS), and Adjustment to Illness Scale (AIS). Data were analyzed using Pearson correlation and stepwise regression.
Findings. Worry, anger rumination and social loneliness was found to have a statistically significant and negative correlation with adjustment to coronary artery disease; that is, with an increase in worry, anger rumination and social loneliness, the level of adjustment to coronary artery disease is reduced. According to Regression analysis, of the three analyzed variables, worry and social loneliness were predictors of adjustment to coronary artery disease, so that worry and worry with social loneliness predicted 35 and 41 percent of the variance of adjustment to coronary artery disease, respectively (p<0.01) .
Conclusion. Taking worry and social loneliness into consideration when planning preventive programs is a necessity. At an interventional level, together with the routine medical treatments, psychological interventions for worry and social loneliness has a great necessity as well.

Background. Cardiovascular disease and its consequences are not limited to the patient, but also have a great impact on the caregiver's life.
Method. This was a descriptive correlational study. The statistical population was all people with referred to the hospitals and medical centers of Urmia with diagnosis of coronary artery disease within the first half of the year. The sample consisted of 130 patients who were selected by convenience sampling method. Data were collected using the questionnaires caregiver burden, marital stress, Kentucky Mindfulness Skills and psychosocial adjustment to illness. Data were analyzed in SPSS by descriptive and inferential statistics.
Findings. The results showed that caregiver burden and marital stress had a statistically significant negative correlation with psychosocial adjustment. Among mindfulness subscales, only “describe” subscale had a statistically significant positive correlation with psychosocial adjustment to illness (P=0.04). The stepwise regression analysis showed that the research model was able to explain 57% of psychosocial adjustment to illness. These findings suggest that caregiver burden and marital stress play an important role in psychosocial adjustment of patients with disease.
Conclusion. It can be concluded that caregiver burden and marital stress play an important role in the primary and secondary prevention of coronary artery disease, and intervention based on the results of this study is recommended.
