Efficacy of Alternative Cardiac Rehabilitation Delivery Formats in Improving Psychological Symptoms after Coronary Artery Bypass Grafting

Background: Health-care systems always strive for alternative cardiac rehabilitation (CR) models to ensure that options available to patients better fit their needs, risk factor profiles, and preferences. We assessed the effects of hospital-based cardiac rehabilitation (HBCR) and hybrid cardiac rehabilitation (HCR) on psychological symptoms (i.e., anxiety, depression, and stress) among patients following coronary artery bypass graft surgery (CABG). Methods: This cross-sectional study recruited 115 CABG patients who were referred to the Department of Cardiac Rehabilitation at Imam Ali Hospital in the Iranian city of Kermanshah between January and May 2016. The patients were assigned to 1 of the 2 programs of HBCR (26 sessions) and HCR (10 sessions). The study population’s psychological symptoms were assessed using the Depression, Anxiety, and Stress Scale (DASS) before and after the intervention, and the data were analyzed using paired t-tests and ANCOVA. Results: A total of 105 (91%) patients concluded the CR program. Respectively, 50.8% and 26.2% of the participants in the HBCR and HCR programs were female. The mean age was 59.6±9.2 years in the HBCR group and 58.7±6.1 years in the HCR group. The ANCOVA results indicated that both HBCR and HCR programs were equally effective in reducing anxiety (P=0.001 vs. P=0.015) and stress (P=0.002 vs. P=0.003) among the CABG patients, while only HBCR was effective in alleviating depressive symptoms (P=0.001). Conclusion: Our results demonstrated the efficacy of HBCR and HCR in diminishing stress and anxiety levels among the CABG patients. However, depression was affected only by HBCR.  

Subjective correlates of stress management in outpatient cardiac rehabilitation: the predictive role of perceived heart risk factors

Introduction: The causal attributions and perceived risk factors can affect patients’ health behaviors. Therefore, the present study aimed to assess (i) the effect of an outpatient cardiac rehabilitation (CR) program on perceived heart risk factors (PHRFs) and on psychological stress, and (ii) the role of changes of PHRFs at pre-post CR in predicting changes in psychological stress.

Methods: In this longitudinal study, 110 CR patients were assessed from June to November 2016 in a hospital in Iran. Perceived heart risk factors and perceived stress were investigated using the PHRFs scale and the Depression, Anxiety, Stress Scale-21, respectively. PHRFs and DASS-21 Stress scale scores were compared before and after 26 sessions of exercise-based CR through paired sample t-tests. In addition, we investigated the effect of PHRF’s change scores on DASS-21 Stress scale scores using linear regression analysis.

Results: Results showed that CR has a little impact in improving the patients’ perception of heart risk factors, However, CR is significantly effective in reducing stress (P < 0.05). Regression analysis evidenced that improvements in patients’ perception of risk factors can significantly predict a reduction in psychological stress (P = 0.030). The model explained 11.2% of the variance in the results.

Conclusion: PHRFs appear to be significant predictive components of CR’s stress reduction. Practitioners should focus on patients’ perception of risk factors to facilitate stress management in CR program.

A Predictive Model of Perceived Susceptibility during the Year before Coronary Artery Bypass Grafting

Background: Based on the protective health model, one of the most important components of etiological factors leading to protective health behaviors is perceived risk or perceived susceptibility. Accordingly, the present study was conducted to assess the uncontrolled and controlled effects of some factors in predicting perceived susceptibility among coronary artery bypass graft (CABG) patients.

Methods: The data for the present cross-sectional study were gathered via assessment of 1052 CABG patients who referred to an outpatient cardiac rehabilitation clinic in a hospital in Iran between 2010 and 2014. The patients completed a checklist containing demographics, risk factors, and a single closed-ended question regarding perceived susceptibility at the beginning of their rehabilitation program. Binary logistic regression analysis was applied to identify the demographic and clinical correlations related to perceived susceptibility.

Results: Totally, 776 (73.8%) of the 1052 participants were male. The mean age of the patients was 58.0 ± 9.1 years. The results revealed that only 13.7% of the patients had perceived susceptibility; in addition, higher age (p value = 0.003) and family history of cardiac diseases (p value = 0.001) were able to significantly predict perceived susceptibility. When the demographic variables were controlled, once again age and family history of cardiac diseases were able to significantly increase perceived susceptibility by approximately 1.04 and 29.6 times, respectively.

Conclusion: Our results revealed that higher age and family history of cardiac diseases were able to significantly predict perceived susceptibility among our CABG patients.

Barriers for the referral to outpatient cardiac rehabilitation: A predictive model including actual and perceived risk factors and perceived control

OBJECTIVE

To assess the roles of demographic factors, actual and perceived risk factors, and perceived control in the referral to cardiac rehabilitation (CR) after coronary artery bypass graft (CABG).

METHODS

In this cross-sectional study, data related to 312 CABG patients in a hospital of the Western part of Iran, gathered through demographics and actual risk factors' checklist, open single item of perceived heart risk factors, life stressful events scale, and perceived control questionnaire. Data analyzed by binary logistic regression.

RESULTS

The results showed that only 8.3% of CABG patients refer to CR. The facilitators of this referral included official employment (P < 0.05), coronary history (P = 0.016), and hyperlipidemia (P = 0.030) but more distance to the CR center (P = 0.042) and perceived physiological risk factor (P = 0.025) are concerned as the barriers for the referral to CR.

CONCLUSION

Providing appropriate awareness about the benefits of CR for patients with regard to their job status, coronary history, and perception about the illness risk factors can be effective in referral to CR. In addition, the presence of CR centers in towns and facilitated achievement to these centers can play a significant role in patients' participation.

Design and standardization of tools for assessing the perceived heart risk and heart health literacy in Iran

Objectives:

The aim is to achieve the standard tools for heart health, the present study aimed to design, develop, and standardize the two questionnaires of perceived heart risk scale (PHRS) and heart health literacy scale (HHLS).

Methods:

The present study was a methodological research conducted on the residents of Kermanshah Province, Iran, using the multi-stage cluster sampling. Further, considering the scientific methods in the psychometric field, the design of the research questionnaires was conducted. In addition, the viewpoints of experts in different domains were qualitatively and quantitatively included to assess the validity of the questionnaires. To assess the reliability of the questionnaires, a sample including 31 subjects was first selected and studied within a fortnight's interval. Then, the reliability and validity of the scales were assessed using factor analysis and Cronbach's alpha in a sample of 771 subjects.

Results:

After reviewing the viewpoints of experts, the items were adjusted and implemented in the first sample at two stages. The results were indicative of the stability and acceptability of the Cronbach's alpha. In addition, the validity and reliability of the questionnaires were confirmed in the second sample too.

Conclusion:

According to the results of the present study, it can be concluded that the two questionnaires of PHRS and HHLS had acceptable reliability and validity.

A hybrid cardiac rehabilitation is as effective as a hospital-based program in reducing chest pain intensity and discomfort

Background

Health care services effort to provide alternative cardiac rehabilitation (CR) models to serve patients according to their preferences and needs. So, the present study aimed to assess and compare the effects of hospital-based and hybrid CR programs on chest pain intensity and discomfort in cardiac surgery patients.

Methods

In this prospective study, 110 cardiac surgery patients were invited to the CR department of a hospital in the western part of Iran between March and July 2016. Patients were divided into two groups: hospital-based and hybrid CR. The hospital-based program included 26 sessions, and the hybrid program included 10 training sessions and exercise. The Brief Pain Inventory and Pain Discomfort Scale were used as research instrument, and data were analyzed using the paired t-test and ANCOVA.

Results

The results indicated that both hospital-based and hybrid CR are effective in reducing the chest pain intensity and discomfort of cardiac surgery patients (P < 0.05). In addition, the comparison of scores before and after treatment using ANCOVA shows that no significant differences were observed between the two programs (P > 0.05).

Conclusions

Traditional hospital-based CR delivery is still the first choice for treatment in developing countries. However, hybrid CR is as effective as a hospital-based program in reducing pain components and it includes only 38% of the total cost in comparison to hospital-based delivery. So, we recommend using hybrid CR according with the recommendations of American Heart Association about using CR for the management of angina symptoms.

Coronary artery bypass graft patients' perception about the risk factors of illness: Educational necessities of second prevention

Background:

Patients’ beliefs about the cause of cardiac disease (perceived risk factors) as part of the global psychological presentation are influenced by patients’ health knowledge. Hence, the present study aimed to assess the relationship between actual and perceived risk factors, identification of underestimated risk factors, and indication of underestimation of every risk factor.

Materials and Methods:

In this cross-sectional study, data of 313 coronary artery bypass graft (CABG) patients admitted to one hospital in the west of Iran were collected through a demographic interview, actual risk factors’ checklist, open single item of perceived risk factors, and a life stressful events scale. Data were analyzed by means of Spearman's correlation coefficients and one-sample Z-test for proportions.

Results:

Although there are significant relations between actual and perceived risk factors related to hypertension, family history, diabetes, smoking, and substance abuse (P < 0.05), there is no relation between the actual and perceived risk factors, and patients underestimate the role of actual risk factors in disease (P < 0.001). The patients underestimated the role of aging (98.8%), substance abuse (95.2%), overweight and obesity (94.9%), hyperlipidemia (93.1%), family history (90.3%), and hypertension (90%) more than diabetes (86.1%), smoking (72.5%), and stress (54.7%).

Conclusion:

Cardiac patients seem to underestimate the role of aging, substance abuse, obesity and overweight, hyperlipidemia, family history, and hypertension more than other actual risk factors. Therefore, these factors should be highlighted to patients to help them to (i) increase the awareness of actual risk factors and (ii) promote an appropriate lifestyle after CABG surgery.

The Role of Oral Contraceptive Pills on Increased Risk of Breast Cancer in Iranian Populations: A Meta-analysis

BACKGROUND

Cancer is one of the main public health issues in the world. Breast cancer is one of the most common types of cancer among women. It is also the second cause of mortality in women. The association between the use of oral contraceptive pills and breast cancer is controversial and a main issue in public health. Some findings have shown that taking these pills does not have a significant effect in increasing the risk of breast cancer, while others have confirmed the carcinogenic effect of these products. These contradictory findings necessitated this meta-analysis, through of all correlated studies in Iran.

METHODS

All published studies were considered from June 2000 until June 2015, using reliable Latin databases like PubMed, Google Scholar, Google search, Scopus, and Science Direct, and Persian database like SID, Irandoc, IranMedex, and Magiran. Finally, 26 papers were selected: 24 studies were case control while two were population based studies. A total of 26 papers with 46,260 participants were assessed since 2001.

RESULTS

Overall estimate of OR for the effect of oral contraceptive pills on breast cancer is 1.521 (CI = 1.25-1.85), which shows that the intervention group had more chance (52%) compared to the control group (P = 0.001). Using these pills increased the risk of breast cancer up to 1.52 times.

CONCLUSIONS

Because of directly increasing levels of estrogen and the role of estrogen in gaining weight indirectly, oral contraceptive pills can stimulate the occurrence of breast cancer. More studies should be conducted for controlling the period of pill use.

What is role of sex and age differences in marital conflict and stress of patients under Cardiac Rehabilitation Program?

BACKGROUND

To investigate the role of sex and age differences in marital conflict and stress of patients who were under cardiac rehabilitation (CR) program.

METHODS

The data of this cross-sectional study were collected from the database of the CR Department of Imam Ali Hospital, Kermanshah, Iran. The demographics and medical data of 683 persons were collected from January 2003 and January 2010 using medical records, the Beck Anxiety Inventory, the Beck Depression Inventory, the Hudson's Index of Marital Stress, and the Structured Clinical Interview for axis I disorders. Data were analyzed through Analysis of Covariance and Bonferroni test.

RESULTS

About 74.8% of the subjects were male. After adjustment for age, educational level, anxiety, and depression-the findings showed that women in CR program had a higher level of marital stress compared to men (54.75 ± 2.52 vs. 49.30 ± 0.89; P = 0.042). Furthermore, it was revealed that women who aged 56-65 years and more experienced higher level of marital stress compared to younger patients (P < 0.050); however, no significant difference was observed between different age groups in male patients (P > 0.050).

CONCLUSION

Marital conflict and stress threaten healthiness of women who aged 56-65 years more prominently than does in males or younger patients. Regarding the effect of marital stress on recurrence of the disease and cardiac-related morbidity and mortality in women, providing effective education and interventions to this group of patients, especially older women and even their spouses could be one of the useful objectives of CR programs.

Those Who Perceive Their Disease as a Physiological or Psychological Risk Factor Experience More Anxiety at the Beginning of the Cardiac Rehabilitation Program

Background:

In a cardiac patient, anxiety is the result of the individual’s perception of the treatment and is characterized by inability to predict, control, or achieve the desired treatment outcomes.

Objectives:

This study was carried out to investigate the extent of clinical anxiety in patients who underwent a cardiac rehabilitation program with different attitudes toward the disease risk factors.

Patients and Methods:

The administrative data of this retrospective study were obtained from the database of the cardiac rehabilitation department of a hospital in Iran. The demographic and clinical information of 603 patients from April 2006 to April 2011 was collected using compiled forms of this database, the Beck anxiety inventory, and the structured clinical interview for axis I disorders. The univariate analysis of variance and the Bonferroni post-hoc analysis were used for data analysis.

Results:

After controlling for gender and educational level, we observed statistically significant differences in the modified means between the patients who considered the behavioral risk factors and those who considered the physiological risk factors (P = 0.012, MD = 5.03) and between the patients who regarded the behavioral risk factors and those who regarded the psychological risk factors (P = 0.0005, MD = 5.32) as the underlying cause of their cardiac condition, which means that the level of anxiety in the physiological and psychological groups was higher than that in the behavioral group.

Conclusions:

The anxiety of patients can be controlled through alteration in their attitudes toward the disease risk factors on the grounds that psychological or physiological factors per se do not trigger the occurrence of the disease, whereas behavioral risk factors, as the controlling agent, significantly influence its occurrence.

Sociodemographic Predictors in Failure to Complete Outpatient Cardiac Rehabilitation

Objective

To investigate the role of sociodemographic factors in failure to complete outpatient cardiac rehabilitation (CR).

Methods

This was a retrospective study that used information obtained from the database of the cardiac rehabilitation department of a cardiac hospital in Iran. Data from 1,050 CR patients treated at the hospital between January 2001 and January 2013 was analyzed using binary logistic regression analysis.

Results

Only 49% of the patients completed the CR program. After adjustment for baseline variables, it was found that the following were significantly associated with failure to complete the CR program: illiteracy (p<0.001), old age (p<0.001), being an employee or retired (p<0.05), having a low capacity for exercise (p<0.001), depression (p<0.001), low anxiety (p<0.001), and not currently being a smoker (p<0.001).

Conclusion

Paying more attention to older patients with low literacy levels and limited exercise capacity, who are employed or retired, and who are not current smokers, and taking therapeutic measures to control psychological complications such as depression, may be effective in ensuring that patients complete outpatient cardiac rehabilitation.

Which Factors Unexpectedly Increase Depressive Symptom Severity in Patients at the End of a Cardiac Rehabilitation Program?

OBJECTIVE

To investigate predictors of depressive symptom aggravation at the end of a cardiac rehabilitation (CR) program.

METHODS

The design of the study was retrospective. The administrative data were obtained from the database of the CR department of a heart hospital in Iran. The demographic and clinical information of 615 CR patients between January 2000 and January 2010 was analyzed using binary logistic regression analysis.

RESULTS

The results showed that 10.7% of the patients completed the CR program with aggravated depressive symptoms. After adjustment for gender, age, and pre-intervention depression score, lower education level (p<0.05) and smoking (p<0.01) were significant predictors of increased depressive symptoms at the end of the program. Our model variables could explain 6% to 13% of the dependent variable variance.

CONCLUSION

The results suggest that targeting patients who are less literate or who smoke could allow for taking the required measures to prevent or control depression at the end of a CR program. It is suggested that future studies consider other variables.

Predictors of Clinical Anxiety Aggravation at the End of a Cardiac Rehabilitation Program

Background:

Anxiety is one of the most primary and common reactions to a cardiac event can lead to hypertension, tachycardia, and high cardiac output.

Objectives:

To investigate the predictors of clinical anxiety aggravation at the end of a cardiac rehabilitation (CR) program.

Patients and Methods:

This retrospective study used a database of a CR ward of a hospital in Iran. The demographic and clinical information of 574 patients participating in the CR program from April 2005 through April 2010 were analyzed. In order to determine the predictors of anxiety, binary logistic regression was performed.

Results:

After adjustment for gender, age and education, the results showed that 16.7% of the patients completed their CR program with increased levels of clinical anxiety. The following study variables were independently predictive of increased anxiety at the end of the CR program: male gender (OR = 2.04, 95% CI = 1.11 to 3.33, P = 0.048), no history of diabetes (OR = 4.24, 95% CI = 172 to 10.44, P = 0.002), family history of cardiac disease (OR = 2.63, 95% CI = 1.03 to 6.74, P = 0.043), and not quitting smoking (OR = 3.29, 95% CI = 1.38 to 7.85, P = 0.007). These variables could explain 9% - 15% of the variance in the dependent variable.

Conclusions:

It is possible to predict higher anxiety levels at the end of the CR program and implement preventive measures to control anxiety by considering certain demographic and clinical variables. Future studies should assess the predictive power of other variables.

The relationship between brain behavioral systems and the characteristics of the five factor model of personality with aggression among Iranian students

Background:

Aggression is one of the negative components of emotion and it is usually considered to be the outcome of the activity of the Behavioral Inhibition and the Behavioral Activation System (BIS/BAS): components which can be considered as predisposing factors for personality differences. Therefore, the purpose of this study was to investigate the relationship between brain behavioral systems and the characteristics of the five factor model of personality with aggression among students.

Methods:

The present study has a correlation descriptive design. The research population included all of the Razi University students in the academic year of 2012-2013. The sampling was carried out with a random stratified method and 360 people (308 female and 52 male) were studied according to a table of Morgan. The study instruments were Buss and Perry Aggression Questionnaire, NEO Personality Inventory (Short Form), and Carver and White scale for BAS/BIS. Finally, SPSS20 was utilized to analyze the data using Pearson correlation, regression analysis, and canonical correlation.

Results:

The data showed a significant positive relationship between the neurosis and agreeableness personality factors with aggression; but there is a significant negative relationship between the extroversion, openness, and conscientiousness personality factors with aggression. Furthermore, there is a significant positive relationship between all the components of brain behavioral systems (impulsivity, novelty seeking, sensitivity, tender) and aggression. The results of regression analysis indicated the personality characteristics and the brain behavioral systems which can predict 29 percent of the changes to aggression, simultaneously.

Conclusions:

According to a predictable level of aggressiveness by the personality characteristics and brain behavioral systems, it is possible to identify the personality characteristics and template patterns of brain behavioral systems for the students which be presented to them as a necessary training in order to control and manage of anger and aggression.

Perceived Stress, Alexithymia, and Psychological Health as Predictors of Sedative Abuse

Background

The harmful effects of sedative medications and substances in conjunction with limited research regarding predictive psychological constructs of drug abuse necessitate further investigation of associated factors. Therefore, the present study aimed to elucidate the roles of perceived stress, alexithymia, and psychological health as predictors of sedative abuse in medical students.

Methods

In this cross-sectional study, 548 students at Kermanshah University of Medical Sciences, Iran, were selected using stratified random sampling. The data were obtained using the Perceived Stress Scale, an alexithymia scale (Farsi version of the Toronto Alexithymia Scale-20), and a General Health Questionnaire to assess psychological health. Data were analyzed using discriminant analyses.

Results

The results demonstrated that the user and non-user of sedative substances groups had significantly different predictive variables (except for social function disorder) (P>0.05). Physical complaints, alexithymia, and perceived stress, which had standard coefficients of 0.80, 0.60, and -0.27, respectively, predicted sedative drug use.

Conclusion

The results of the present study indicate that perceived stress, alexithymia, physical complaints, anxiety, and depression are associated with sedative drug abuse.

Non-Coronary Patients with Severe Chest Pain Show More Irrational Beliefs Compared to Patients with Mild Pain

Background

Despite providing insufficient medical evidence of the existence of a real cardiac condition, patients with non-coronary chest pain still interpret their pain incorrectly. The present study, therefore, sought to compare the irrational beliefs in non-coronary patients with mild chest pain against those with severe chest pain.

Methods

A cross-sectional design was used. The statistical population comprised non-coronary patients who presented to the Heart Emergency Center of Kermanshah city, Iran. Using a matching method, 96 participants were selected and studied in two groups of 48. The instruments used were the Comorbidity Index, Brief Pain Index, and the Jones Irrational Beliefs Test (short-form). The multivariate analysis of variance, chi-square test, and t-test were used for data analysis.

Results

Controlling for the effects of age and comorbid conditions, the severity of three types of irrational beliefs, including emotional irresponsibility (P<0.001), hopelessness changes (P<0.001), and problem avoiding (P=0.002) was higher among patients with severe chest pain (according to effect level). However, in terms of demand for approval, no difference was seen between the two groups (P=0.180).

Conclusion

Non-coronary patients with severe chest pain showed a greater number of irrational beliefs in comparison to patients with mild pain. Irrational beliefs are common mental occurrences in patients with non-coronary chest pain, and they should be attended to by health professionals, especially in severe non-coronary chest pain. Further investigation to determine the association between irrational beliefs and non-coronary chest pain is necessary.

The Intervening Role of Alexithymia in the Relationship between Attachment Styles and Test Anxiety among Gifted High School Students

Background

Given the importance of test anxiety among gifted students, the present study was conducted to assess the intervening role of alexithymia in the relationship between test anxiety and attachment styles.

Methods

By means of simple random sampling, 300 participants were selected out of all the students at two high schools in Khorramabad, which are affiliated with the Iranian National Organization for Development of Exceptional Talents (SAMPAD). Test anxiety, alexithymia, and attachment style questionnaires were used for data collection. Pearson correlation and path analysis tests were used to analyze the data.

Results

The results showed a positive relationship between test anxiety and avoidant and anxious attachment styles. Alexithymia and test anxiety were also positively related. Moreover, the results indicated that 12% of changes in test anxiety were explained by avoidant and anxious attachment styles as well as alexithymia. The relationship between the avoidant attachment style and test anxiety was 0.06 through alexithymia. However, no significant relationship between anxious attachment and test anxiety through alexithymia was found.

Conclusion

The avoidant attachment style leads to test anxiety when the level of alexithymia increases in an individual.

Reducing Irrational Beliefs and Pain Severity in Patients Suffering from Non-Cardiac Chest Pain (NCCP): A Comparison of Relaxation Training and Metaphor Therapy

Background

Patients suffering from non-cardiac chest pain (NCCP) can interpret their chest pain wrongly despite having received a correct diagnosis. The objective of this study was to compare the efficacy of the relaxation method with metaphor therapy for reducing irrational beliefs and pain severity in patients with NCCP.

Methods

Using a randomized controlled trial, 33 participants were randomly divided into a relaxation training group (n= 13), a metaphor therapy group (n = 10), and a control group (n = 10), and were studied for 4 weeks. The two tools used in this research were the Brief Pain Inventory (BPI) index for determining the degree of pain and the short version of the Jones Irrational Belief Test. Metaphor therapy and a relaxation technique based on Öst's treatment were used as the interventions. The collected data were analyzed with a multivariate analysis of covariance (MANCOVA), a Chi-square test, and the Bonferroni procedure of post-hoc analysis.

Results

The relaxation training method was significantly more effective than both metaphor therapy and the lack of treatment in reducing the patients' beliefs of hopelessness in the face of changes and emotional irresponsibility, as well as the pain severity. Metaphor therapy was not effective on any of these factors. In fact, the results did not support the effectiveness of metaphor therapy.

Conclusions

Regarding the effectiveness of the relaxation method as compared with metaphor therapy and the lack of treatment in the control group, this study suggests that relaxation should be paid greater attention as a method for improving the status of patients. In addition, more studies are needed to determine the effectiveness of metaphor therapy in this area.
