Background: The purpose of this study was to evaluate the longitudinal effect of the health education program on improving health-related quality of life in patients with coronary artery bypass graft surgery.
Materials and methods: Seventy patients were randomly selected for the study before operation, and assigned equally in 2 groups of experiment and control. Finally, seven patients were excluded and the study was carried out on 63 patients. The demographic information and Nottingham Health Profile (NHP) questionnaire were completed prior to surgery. Patients in the experimental group received the educational intervention. Educational intervention was according to Mico's education planning model. For second phase of Mico's model, knowledge, attitude and performance were measured. These patients were followed up to 1-month and one-year after educational intervention. SPSS software was used for data analysis.
Results: Significant improvements in quality of life were identified between two groups in energy, sleep and social isolation domains when compared between three time intervals.
 Conclusion: Results have revealed that health education has longitudinal effect on improving the quality of life in patients with CABG.

Background: The number of coronary artery bypass grafts is increasing as one of the most effective treatments. Adherence to the treatment regimen is one of the determinants of the effectiveness of this intervention. The aim of this study was to evaluate the compliance of treatment regimen in patients underwent coronary artery bypass graft surgery in Tehran's Social Security Hospitals.
Materials and methods: This descriptive-analytical study was performed on 255 patients in Milad and Shahid Lavasani Hospitals in 2017. Data were collected through a demographic and adherence to treatment regimen questionnaire. Data were analyzed using SPSS v18 software by applying descriptive statistics and regression modeling.
Results: Most subjects had a rather favorable diet (98.8%), drug (72.9%) and physical activity (90.6%) adherence. In terms of drug and physical activity, the share of people who had unfavorable compliance was 25.9% and 9.4%, respectively. The mean score for the treatment regimen was 3179.76. Gender, having caregivers, history and frequency of admission, blood lipids, and blood pressure had a role in explaining the rate of compliance with the treatment regimen.
Conclusion: The findings of this study showed that the overall adherence rate of the treatment regimen in patients underwent coronary artery bypass graft surgery was at a relatively desirable level. The importance of adherence to the treatment regimen in preventing recurrence of disease and future disabilities encourages us to design and implement some interventions to improve the patients' willingness and ability to adhere the treatment regimen.

Background: Stress immunization training is a combination of the best cognitive-behavioral elements. The aim of this study was to investigate the effectiveness of stress-induced immunostimulatory­ training on psychophysiologic indices (salivary cortisol) and psychological indicators (anxiety, stress and depression) in patients with coronary artery bypass graft.
Materials and methods: In this Semi-experimental study with control group and pre-test-post-test design, the statistical population included patients who had coronary artery bypass surgery and referred to the Rehab center of Tehran Heart Hospital. 30 subjects were selected by simple random sampling and randomly assigned to experimental and control groups. The instrument of this study was the Kit cortisol and  DASS-21 scale of depression, anxiety and stress. The experimental group was exposed to an independent variable (training for immunization against stress) for 10 sessions of 90 minutes. To analyze the data, multivariate covariance analysis, univariate analysis of covariance in Mancoe text and SPSS software were used.
Results: Stress immunization training had an effect on salivary cortisol (p <0.001), depression (p <0.001), stress (p <0.001) and anxiety (p <0.001) in the experimental group.
Conclusion: Reducing negative emotions following stress immunization training plays an important role in preventing the more severe complications of heart disease; so interventions based on the results of this study are recommended for patients with cardiac diseases.
