A pilot randomized controlled trial to assess the effect of Islamic spiritual intervention and of breathing technique with heart rate variability feedback on anxiety, depression and psycho-physiologic coherence in patients after coronary artery bypass surgery

BackgroundThis study investigated the effects of Islamic religious and breathing techniques with heart rate variability (HRV) biofeedback therapies on HRV and psycho-physiologic coherence (resonance frequency), depression and anxiety in coronary artery bypass graft surgery (CABG) patients.MethodsSixty CABG patients were chosen and randomly assigned to religious, breathing techniques and control groups. The experimental groups received 8 weeks of treatments; a 2-h session with home works in each week. The control group received only their normal hospital interventions. The groups’ depression, anxiety, HRV and psycho-physiologic coherence levels were assessed before and after the interventions by DASS-21 for depression and anxiety, and em-wave desktop software for HRV and psycho-physiologic coherence. The data were analyzed using ANCOVA with Bonferroni Comparison test and descriptive tests in SPSS software.ResultsThe findings showed that there were significant differences in psycho-physiologic coherence (HRV), depression and anxiety scores among the three groups in the post-tests. In fact, depression and anxiety were reduced more in the religious group, while psycho-physiologic coherence raised more in the breathing with the HRV feedback group.ConclusionThe results showed that both Islamic religious and breathing techniques with HRV biofeedback therapies can be used in rehabilitation programs for CABG patients in clinics and hospitals.

Comparison of the Effects of Islamic Spiritual Educations and Breathing Techniques with Heart Rate Variability Feedback Therapies on Heart Rate Variability, Psychophysiological Coordination and Stress in Patients Undergoing Coronary Artery Bypass Graft Surgery

Background: Patients with coronary artery disease also have psychological disorders, such as stress and depression, especially if they underwent coronary artery bypass graft (CABG) surgery; a type of bypass surgery that forms new routes around narrowed and blocked coronary arteries, permitting increased blood flow to deliver oxygen and nutrients to the heart muscle. Objectives: The current study aimed at comparing the effect of Islamic educations and breathing techniques with heart rate variability (HRV) biofeedback therapies on HRV, psychophysiological coordination, and stress in patients undergoing CABG. Methods: A total of 60 patients who underwent CABG surgery were selected and randomly assigned to three equal groups of the Islamic educations, breathing techniques, and control. The experimental groups received an eight-week intervention as a two-hour session per week with home practices. The control group received only the routine hospital care. The stress, HRV, and psychophysiological coordination levels of the subjects were evaluated before and after the interventions in the three groups using depression, anxiety, and stress scale-21 for stress and emWave Desktop software for HRV and psychophysiological coordination. The data were analyzed using ANCOVA and descriptive tests with SPSS version 21. Results: The results showed a significant difference among the three groups in the increase of HRV and psychophysiological coordination and decrease of stress. Moreover, stress level reduced more in the Islamic educations group, while HRV and psychophysiological coordination levels increased more in the breathing techniques group. Conclusions: Based on the results, it is recommended using both Islamic educations and breathing techniques as well as HRV biofeedback therapies in rehabilitation programs for patients undergoing CABG in hospitals.

Integrating Non-Technological and Technological Peripheral Biofeedback in Counseling

Neurocounseling, the integration of neurobiology into the practice of counseling, is gaining attention and empirical support within the counseling field. Clients and clinical mental health counselors appear eager for effective mind–body tools that are accessible during, between, and beyond sessions. Peripheral biofeedback encompasses a host of such interventions, including technological (e.g., heart rate variability feedback) and non-technological (e.g., observation) approaches. Non-technological approaches are cost-effective tools that can enhance the efficacy of other counseling approaches and may serve to improve client outcomes. Integrating non-technological and technological peripheral biofeedback is a promising direction for clinical practice. In this article, the authors provide an overview of the key components of the stress-response system, the neurobiology of breath and self-regulation, and the related elements of peripheral biofeedback. The authors describe a case example, identify gaps in the knowledge base, and explore the implications for clinical practice and research.

New Hope for Correctional Officers: An Innovative Program for Reducing Stress and Health Risks

This study investigated the impact of a new stress management program on physiological and psychological stress and health risk factors among 75 correctional officers. The experimental group received training in emotion self-regulation techniques intended to reduce stress and health risk factors. Practice of the techniques was enhanced by heart rate variability feedback, which helped participants learn and sustain use of the self-management tools. Measures of physiological stress included cortisol, DHEA, cholesterol, triglycerides, fasting glucose levels, 10-min resting electrocardiogram, heart rate variability, and blood pressure. Three psychological questionnaires assessed emotional stress and work-related variables. There were significant improvements in the experimental group in cholesterol, glucose, heart rate, blood pressure and positive outlook and significant reductions in overall psychological distress. There were significant increases in productivity, motivation, goal clarity, and perceived support. The mean difference between pre- and post-intervention projected health care costs was calculated to be $1,179 per employee per year.

Impact of a Workplace Stress Reduction Program on Blood Pressure and Emotional Health in Hypertensive Employees

This study examined the impact of a workplace-based stress management program on blood pressure (BP), emotional health, and workplace-related measures in hypertensive employees of a global information technology company. Thirty-eight (38) employees with hypertension were randomly assigned to a treatment group that received the stress-reduction intervention or a waiting control group that received no intervention during the study period. The treatment group participated in a 16-hour program, which included instruction in positive emotion refocusing and emotional restructuring techniques intended to reduce sympathetic nervous system arousal, stress, and negative affect, increase positive affect, and improve performance. Learning and practice of the techniques was enhanced by heart rate variability feedback, which helped participants learn to self-generate physiological coherence, a beneficial physiologic mode associated with increased heart rhythm coherence, physiologic entrainment, parasympathetic activity, and vascular resonance. BP, emotional health, and workplace-related measures were assessed before and 3 months after the program. Three months post-intervention, the treatment group exhibited a mean adjusted reduction of 10.6 mm Hg in systolic BP and of 6.3 mm Hg in diastolic BP. The reduction in systolic BP was significant in relation to the control group. The treatment group also demonstrated improvements in emotional health, including significant reductions in stress symptoms, depression, and global psychological distress and significant increases in peacefulness and positive outlook. Reduced systolic BP was correlated with reduced stress symptoms. Furthermore, the trained employees demonstrated significant increases in the work-related scales of workplace satisfaction and value of contribution. Results suggest that a brief workplace stress management intervention can produce clinically significant reductions in BP and improve emotional health among hypertensive employees. Implications are that such interventions may produce a healthier and more productive workforce, enhancing performance and reducing losses to the organization resulting from cognitive decline, illness, and premature mortality.
