Background: Numerous studies have examined the effectiveness of behavioral therapy based on the acceptance and assessment of anxiety in patients with cardiovascular disease. However, research that has examined the effectiveness of acceptance-based behavior therapy on hidden anxiety, overt anxiety, and hypertension in cardiovascular patients has been neglected. Aims: To investigate the effectiveness of acceptance therapy based on acceptance of hidden anxiety, overt anxiety and hypertension in cardiovascular patients. Method: The present study was a randomized controlled clinical trial with a pretest-posttest design with a control group with baseline measurement after 3 months of intervention and follow-up. The statistical population included all cardiovascular patients referred to Baqiyatallah Hospital in Tehran from June to September 2017. Twenty-four patients were selected as target samples based on sampling and randomly assigned to two experimental and control groups (12 people). The instruments of this study were researcher-made demographic questionnaire (2019), open and hidden anxiety questionnaire of Spielberger (Gerash and Lashn, 1970) and acceptance and commitment-based behavioral therapy protocol (Finance, Ghaderi, Dahl, Niger and Inibrink, 2019). Data analysis was performed using repeated size analysis of variance. Results: Acceptance-based behavioral therapy had a significant effect on reducing hidden anxiety, overt anxiety, and blood pressure (p< 0/001). the results obtained in the follow-up phase were constant. Conclusions: Patients who attended admission-based behavioral therapy sessions had reduced levels of hidden anxiety, overt anxiety, and high blood pressure.

Background: High blood pressure is one of the most common and important factors threatening individuals’ mental health and quality of life. Accordingly, the study of important psychological factors such as cognitive regulation of emotion and defense styles used by patients with high blood pressure, and the impact of these variables on their quality of life can help them improve their psychological state.
Aims: The purpose of this study was to investigate the structural model of the relationship between cognitive emotion regulation and defensive lifestyles with quality of life mediated by Alexithymia in patients with hypertension.
Methods: The present study is descriptive and of correlations and structural equations type. The statistical population includes 700 patients with hypertension who referred to Shiraz Heart Hospital in the spring and summer of 1398. 480 patients were selected from among them. The research instruments included the Cognitive Emotion Regulation Questionnaire of Garnefski et al. (2007), the Defense Styles Questionnaire of et al. (1993), Quality of Life Questionnaire of the World Health Organization (1996) and the Toronto Alexithymia Scale-20 Questionnaire by Tyler et al. (1994). Data were analyzed by Kolmogorov-Smirnov test , linear regression and structural equation modeling using SPSS 25 and LISREL 8/8 software.
Results: The relationship between emotional cognitive regulation variables and defense styles with quality of life variable mediated by alexithymia in patients with hypertension is significant
(P< 0.001).
Conclusion: Applying cognitive emotion regulation strategies and defensive styles to overcome alexithymia by patients with high blood pressure can affect the quality of life of these patients.

Background: Numerous studies confirm the effect of psychological factors on the occurrence of cardiovascular diseases such as blood pressure. These diseases affect the quality of people's emotions and health. So far, various treatments have been performed to reduce blood pressure, but it seems that the role of psychological treatments such as treatment based on acceptance and commitment in regulating emotions and consequently reducing blood pressure has not been paid enough attention.
Aims: The aim of the present study was to investigate the efficacy of acceptance and commitment therapy on emotion regulation and blood pressure reduction in people with coronary heart disease.
Methods: The present research method was applied and quasi-experimental designs of pre-test-post-test and 6-month follow-up with a control group. The statistical population of this research included all people with coronary heart disease who were referred to Shahid Beheshti Hospital in Nowshahr. The sample of this study includes 30 people with coronary heart disease who were selected using Convenience Sampling. The data were obtained using the emotion regulation questionnaire of Granfsky et al. (2001) and a sphygmomanometer. The protocol used in this research was based on the proposal of Herbert and Furman (2011), which was designed and implemented in 8 sessions of 60 minutes. The data were analyzed using the Mancova method and analysis of variance with repeated measurements, and the above statistical analyzes were performed using SPSS-26 software.
Results: The results showed that there is a significant difference between the mean scores before and after the intervention between the experimental and control groups (p<0.05). The average blood pressure of the subjects in the pre-test of the experimental group was 15.16 and in the post-test stage, it was reduced to 12.83, while there was no significant change in the control group. Finally, the findings indicated that the treatment based on acceptance and commitment statistically affects emotion regulation and blood pressure reduction in people with coronary heart disease.
Conclusion: It can be concluded that the treatment based on acceptance and commitment can be used as an effective intervention to improve emotion regulation and reduce blood pressure in people with coronary heart disease.
