Effects of relaxation intervention in phase II cardiac rehabilitation: replication and extension

Treatment of Anxiety in Patients With Coronary Heart Disease: A Systematic Review

BACKGROUND

Anxiety is common in patients with coronary heart disease (CHD) and is associated with an increased risk for adverse outcomes. There has been a relative paucity of studies concerning treatment of anxiety in patients with CHD.

OBJECTIVE

We conducted a systematic review to organize and assess research into the treatment of anxiety in patients with CHD.

METHODS

We searched CCTR/CENTRAL, MEDLINE, EMBASE, PsycINFO, and CINAHL for randomized clinical trials conducted before October 2016 that measured anxiety before and after an intervention for patients with CHD.

RESULTS

A total of 475 articles were subjected to full text review, yielding 112 publications that met inclusion criteria plus an additional 7 studies from reference lists and published reviews, yielding 119 studies. Sample size, country of origin, study quality, and demographics varied widely among studies. Most studies were conducted with nonanxious patients. The Hospital Anxiety and Depression Scale and State-Trait Anxiety Inventory were the most frequently used instruments to assess anxiety. Interventions included pharmacological, counseling, relaxation-based, educational, or "alternative" therapies. Forty (33% of total) studies reported that the interventions reduced anxiety; treatment efficacy varied by study and type of intervention. Elevated anxiety was an inclusion criterion in only 4 studies, with inconsistent results.

CONCLUSION

Although there have been a number of randomized clinical trials of patients with CHD that assessed anxiety, in most cases anxiety was a secondary outcome, and only one-third found that symptoms of anxiety were reduced with treatment. Future studies need to target anxious patients and evaluate the effects of treatment on anxiety and relevant clinical endpoints.

Cardiac rehabilitation past, present and future: an overview

Cardiac Rehabilitation has evolved over the past decades from a simple monitoring for the safe return to physical activities to a multidisciplinary approach that focuses on patient education, individually tailored exercise training, modification of the risk factors and the overall well-being of the cardiac patients. It has been proven to be an effective tool for the care of the patients with heart disease. Recent research in cardiac rehabilitation has demonstrated that tremendous benefits can be derived from the optimal use of cardiac rehabilitation in patients with various cardiac pathologies including ischemic heart disease, heart failure and post heart surgery. The benefits of cardiac rehabilitation include mortality reduction, symptom relief, reduction in smoking and improved exercise tolerance, risk factors modification and the overall psychosocial wellbeing. Unfortunately, cardiac rehabilitation remains considerably underutilized mainly because of referral problems and poor enrollment. The development of alternate approaches and the use of transtelephonic and other means of monitoring and surveillance will help expand the utilization of cardiac rehabilitation.

Comparison of cardiac rehabilitation programs combined with relaxation and meditation techniques on reduction of depression and anxiety of cardiovascular patients

Cardiovascular disease (CVD) is a major cause of death in developed countries. Most cardiac rehabilitation programs include psychological interventions. The aim of this study was to determine the effectiveness of rehabilitation techniques in cardiac patients including psychological-physical interventions such as Meditation and Relaxation. We enrolled 45 patients with CVD and depression. The patients were allocated to 3 groups (Relaxation, Meditation and Control). There was a significant reduction on depression, systolic blood pressure and heart rate in the Meditation group compared with the control group. Our findings suggest that meditation techniques have better outcomes in cardiac patients for improving depression, reduction of systolic and diastolic blood pressure, and heart rate than relaxation techniques.

The effect of cardiac rehabilitation with relaxation therapy on psychological, hemodynamic, and hospital admission outcome variables

PURPOSE

To examine the effect of a cardiac rehabilitation program with relaxation therapy (CPRT) in comparison with cardiac rehabilitation alone on psychological stress, hemodynamic variables, cardiac risk factors, and cardiac-related hospital admissions in patients with coronary artery disease.

METHODS

Patients (N = 81) were randomly assigned to either a 12-week cardiac rehabilitation program alone (CPA) or a CPRT. Perceived stress, blood pressure, heart rate, rate-pressure product value, total cholesterol level, body mass index, smoking status, and physical activity were recorded at baseline and following the 12-week intervention. Cardiac-related hospital admissions were analyzed in a 2-year follow-up.

RESULTS

Perceived stress declined in both groups, although this improvement was significantly superior in the CPRT (31.5 +/- 4.9 vs 23.4 +/- 4.1; P <or= .0001). CPRT, but not CPA, had significantly lower heart rate, blood pressure, and rate-pressure product values after the program (P <or= .0001). Both groups improved smoking status, physical activity, body mass index, and total cholesterol level. During follow-up, the odds of being admitted to the hospital with cardiac-related problems, after adjusting for heart rate, blood pressure, smoking status, physical activity status, and total cholesterol (OR, 0.37; 95% CI, 0.045-2.98), was not significantly different between groups.

CONCLUSIONS

Relaxation therapy was associated with a positive effect on psychological stress and hemodynamic variables beyond that promoted by cardiac rehabilitation alone.

Effects of relaxation therapy on psychologic distress and symptom status in older Chinese patients with heart failure

BACKGROUND

Previous studies demonstrated the effects of progressive muscle relaxation training (PMRT) on improvements in the health outcomes of cardiac patients. This study examined the effects of PMRT on the psychologic status and symptoms of older Chinese patients with heart failure.

METHODS

In a longitudinal, randomized, and controlled study, 59 patients were allocated to receive a PMRT program and 62 were provided with the attention placebo. The PMRT program included two PMRT sessions, one revision workshop, twice-daily PMRT home practices, and a biweekly telephone follow-up call. The attention placebo included a regular telephone call at a schedule similar to that made by the interventionist of the PMRT program with the intervention group. Main outcome measures, including psychologic distress, dyspnea, and fatigue, were taken at baseline, the 8th week, and the 14th week.

RESULTS

A medium effect on psychologic distress in favor of the PMRT program was detected. Patients practicing PMRT however only demonstrated a nonsignificant trend of greater improvement in symptom status.

CONCLUSION

Progressive muscle relaxation training seems to be useful as an adjunctive nonpharmacologic treatment modality in the management of heart failure.

Non-Pharmacological Interventions in Older People with Heart Failure: Effects of Exercise Training and Relaxation Therapy

BACKGROUND

Effective management of heart failure relies on optimal use of non-pharmacological therapy alongside medical treatment. Yet, there is an inadequate use of non-pharmacological therapy in caring for older people with heart failure.

OBJECTIVE

To examine the effects of relaxation therapy and exercise training on psychological outcomes and disease-specific quality of life of older heart failure patients.

METHODS

Subjects undertook relaxation (n = 59), exercise training (n = 32) or received attention placebo (n = 62) for 12 weeks. The relaxation group attended two training sessions, one revision workshop, and continued with twice-daily taped-directed home relaxation practice, with support from the intervener through bi-weekly telephone contact, for 12 weeks. The exercise group undertook 12 weekly sessions of resistance training and aerobic exercise and thrice weekly home exercise. The control group received regular telephone calls for general 'greetings'.

RESULTS

The relaxation and exercise groups reported a significantly greater improvement in psychological [F(2, 149) = 6.69, p = 0.002] and various disease-specific quality of life outcomes [dyspnea: F(2, 149) = 5.72, p = 0.004; fatigue: F(2, 149) = 3.78, p = 0.25; emotion: F(2, 149) = 6.68, p = 0.001], compared with those who received the attention placebo. While relaxation therapy was more effective to reduce psychological distress, with depression in particular (p < 0.001), exercise therapy worked better to control fatigue symptoms (p = 0.03).

CONCLUSION

Relaxation therapy and exercise training are effective to improve the psychological and physical health of older heart failure patients. They should be used as an individual treatment modality, or as care components of a disease management program.

An Evaluation of Two Behavioral Rehabilitation Programs, Qigong Versus Progressive Relaxation, in Improving the Quality of Life in Cardiac Patients

OBJECTIVES

The aim of the current study was to evaluate and compare two different behavioral rehabilitation programs in improving the quality of life in cardiac patients in Hong Kong.

DESIGN AND SETTING

The current study was carried out in the outpatient unit of Occupational Therapy Department in the United Christian Hospital, Hong Kong. Convenience sampling with referral from the cardiac specialty was used in the present study.

SUBJECTS

A total of 65 subjects, with a mean age 65 (range, 42 to 76), were recruited in the study. The cardiac diseases included myocardial infarct, postcoronary intervention, valve replacement, and also ischemic heart disease.

INTERVENTIONS

Patients were alternately allocated to the two groups. The first group of patients received instructions and practiced on progressive relaxation. The second group of patients underwent training in qigong. A total of eight sessions were conducted and each session lasted 20 minutes.

OUTCOME MEASURES

Demographic and clinical data such as gender, age, and systolic and diastolic blood pressure were recorded. The psychological and Quality of Life assessment was performed using the Chinese versions of Short Form 36 (C-SF36), State-Trait Anxiety Inventory (C-STAI), and General Health Questionnaire (C-GHQ-12).

RESULTS

Fifty-nine (59) subjects (44 men and 15 women) completed all eight rehabilitation sessions in the study. Patients allocated to the two treatment groups had comparable baseline characteristics. Progressive relaxation was more effective in reducing blood pressures compared to qigong. Relaxation appeared to be particularly beneficial in somatic domains. qigong group demonstrated greater improvement in psychologic measures in addition to reduction in systolic blood pressure.

CONCLUSIONS

Progressive relaxation and qigong exercise improved the quality of life for cardiac patients with reference to certain physiologic and psychologic measures. The result was supported by previous studies and literature reviews on qigong in terms of its effect on the psychologic dimension.

Cardiopulmonary Rehabilitation and Cancer Rehabilitation. 1. Cardiac Rehabilitation Review

Cardiac rehabilitation includes not only the rehabilitation of people with ischemic heart disease but also those with congestive heart failure, heart transplantation, congenital heart disease, and other conditions. New advances in medical treatment have arisen, and there are new approaches in treatment, including alternative medicine and complementary care. New surgical approaches that help restore cardiac function have also been introduced, and rehabilitation professionals must be aware of these advances and be able to incorporate this knowledge into the practice of rehabilitation medicine.

OVERALL ARTICLE OBJECTIVES

(a) To identify major categories of cardiac disease, (b) to elucidate appropriate interventions and support for patients with coronary artery disease, (c) to describe the new interventions available for the treatment of cardiac disease, and (d) to describe the appropriate role of cardiac rehabilitation for people with various forms of cardiac disease.

Relaxation therapy for rehabilitation and prevention in ischaemic heart disease: a systematic review and meta-analysis

AIMS

To establish the effects of relaxation therapy on the recovery from a cardiac ischaemic event and secondary prevention.

METHODS AND RESULTS

A search was conducted for controlled trials in which patients with myocardial ischaemia were taught relaxation therapy, and outcomes were measured with respect to physiological, psychological, cardiac effects, return to work and cardiac events. A total of 27 studies were located. Six studies used abbreviated relaxation therapy (3 h or less of instruction), 13 studies used full relaxation therapy (9 h of supervised instruction and discussion), and in eight studies full relaxation therapy was expanded with cognitive therapy (11 h on average). Physiological outcomes: reduction in resting heart rate, increased heart rate variability, improved exercise tolerance and increased high-density lipoprotein cholesterol were found. No effect was found on blood pressure or cholesterol. Psychological outcome: state anxiety was reduced, trait anxiety was not, depression was reduced. Cardiac effects: the frequency of occurrence of angina pectoris was reduced, the occurrence of arrhythmia and exercise induced ischaemia were reduced. Return to work was improved. Cardiac events occurred less frequently, as well as cardiac deaths. With the exception of resting heart rate, the effects were small, absent or not measured in studies in which abbreviated relaxation therapy was given. No difference was found between the effects of full or expanded relaxation therapy.

CONCLUSION

Intensive supervised relaxation practice enhances recovery from an ischaemic cardiac event and contributes to secondary prevention. It is an important ingredient of cardiac rehabilitation, in addition to exercise and psycho-education.

[Usefulness of relaxation techniques for patients with ischaemic cardiopathy: intervention in a health district]

OBJECTIVE

To determine the effectiveness of a programme of relaxation used in primary care for patients with ischaemic cardiopathy (IC) through evaluation of the anxiety levels and the quality of life of these patients.

DESIGN

Controlled intervention study without randomisation.

SETTING

Two primary care teams in the city of Sabadell.

PARTICIPANTS

Patients from 15 to 69 years old with IC: intervention group (IG), 57 patients; control group (CG), 47. Interventions. In the IG, conventional treatment and relaxation techniques (RT). In the CG, conventional treatment.

MAIN MEASUREMENTS

Degree of anxiety was measured by means of the STAI scale-questionnaire. Quality of life was measured by means of the SF-36 health questionnaire. Blood pressure and smoking were recorded.

RESULTS

At 12 months, 70% of patients practised relaxation at least for a short time. In the IG, anxiety dropped significantly at 3, 6, and 12 months, especially the anxiety characteristics scale, which was still significant at 12 months (P=.002). Quality of life at 3 and 6 months in the IG showed better scores in most dimensions except body pain. At 12 months, scores continued to be better than at the start (social function P=.012), except in the mental health dimension. No significant changes were found in blood pressure or tobacco consumption.

CONCLUSIONS

Our results suggest that an RT workshop in primary care is beneficial if correctly applied and leads to improved quality of life.

Interactive Guided ImagerySMTherapy with Medical Patients: Predictors of Health Outcomes

OBJECTIVES

To assess whether Interactive Guided Imagery (IGI) is helpful to medical patients and to identify factors that contribute to positive outcomes.

DESIGN

A prospective cohort study of 323 medical patients who received 6 IGI sessions on a weekly basis. Patients and practitioners completed questionnaires at the beginning, middle, and end of the 6 IGI sessions. The questionnaires assessed the patients' ability to do IGI, the quality of the practitioner-patient interaction, possible confounding variables, and enabling factors. The hypothesis was that measures of the process of doing IGI and the practitioner-patient relationship would predict outcomes.

SUBJECTS/SETTING

The subjects were all patients seeking treatment at California Pacific Medical Center in San Francisco, and Marin General Hospital in Greenbrae, CA.

INTERVENTION

Using IGI interactively is a cognitive-behavioral intervention designed to help patients relax by using mental images to discover and cultivate healing intentions, and to reflect on the meaning of these images.

MEASURES

The individual measures to assess the patients' ability to do IGI and measures of the practitioner-patient relationship were factor-analyzed to use as predictor variables in a multiple regression. Similarly, the questionnaire items measuring cognitive, emotional, behavioral, and spiritual benefits of IGI were factor-analyzed into factors representing "insight" and "all other" benefits.

RESULTS

The multiple regression shows that both process and practitioner-patient interaction factors significantly contributed to a combined 40% of the variance in patients' ratings of insight into the nature of their problem and to becoming aware of an aspect of self, F(4,56) = 9.4, p < 0.005. The same process and interaction factors were less strongly related to the other outcomes, r2 = 0.14, F(4,56) = 2.3, p = 0.06. None of the demographic, confounding, or enabling factors was related to the outcome measures.

CONCLUSIONS

The process of doing IGI and the relationship with the practitioner were both independently associated with the patients' insight into their health problems.

Nursing Outcomes in Coronary Heart Disease

Nursing research has contributed to our knowledge of patients with coronary heart disease (CHD), although much of the research has focused on acute cardiac events. Active and ongoing programs of research into CHD patient outcomes are essential as significant gaps remain. Consistently effective strategies to help patients change risk behaviors, recognize salient symptoms, manage their CHD and ischemic symptoms, improve function and quality of life, and prevent subsequent coronary events are needed, especially in the elderly and those with multiple comorbidities.

Audio-visual relaxation training for anxiety, sleep, and relaxation among Chinese adults with cardiac disease

The long-term effect of an audio-visual relaxation training (RT) treatment involving deep breathing, exercise, muscle relaxation, guided imagery, and meditation was compared with routine nursing care for reducing anxiety, improving sleep, and promoting relaxation in Chinese adults with cardiac disease. This research was a quasi-experimental, two-group, pretest-posttest study. A convenience sample of 100 cardiology patients (41 treatment, 59 control) admitted to one large medical center hospital in the Republic of China (ROC) was studied for 1 year. The hypothesized relationships were supported. RT significantly (p <.05) improved anxiety, sleep, and relaxation in the treatment group as compared to the control group. It appears audio-visual RT might be a beneficial adjunctive therapy for adult cardiac patients. However, considerable further work using stronger research designs is needed to determine the most appropriate instructional methods and the factors that contribute to long-term consistent practice of RT with Chinese populations.

The Use of Complementary and Alternative Medicines by Surgical Patients: A Follow-Up Survey Study

In a previous study, we indicated that 42% of surgical outpatients are interested in using acupuncture as a treatment modality for preoperative anxiety. We designed this follow-up survey to assess differences in attitude toward complementary-alternative medical therapies (CAM) between patients undergoing outpatient surgeries and those undergoing inpatient surgeries. The results indicate that most surgical patients (57.4%) use some form of CAM, including self-prayer (praying for their own health; 29%), chiropractic treatment (23%), massage therapy (15%), relaxation (14%), herbs (13%), megavitamins (9%), and acupuncture (7%). Inpatient surgical respondents reported using self-prayer more than outpatient surgical respondents, but no other differences in CAM use were found between inpatient and outpatient respondents. More inpatient respondents reported disclosing their usage of CAM to perioperative physicians than did outpatient respondents. Most surgical patients were willing to accept CAM as part of their perioperative management but were not willing to pay out-of-pocket for CAM treatment. The leading CAM therapies that fewer of the respondents were willing to pay for out-of-pocket included relaxation, massage, chiropractic medicine, herbs, and acupuncture.

IMPLICATIONS

Most surgical patients use some form of complementary-alternative medical therapies (CAM) and are willing to accept CAM therapy as part of their perioperative management.

Effects of relaxation and imagery on the sleep of critically ill adults

The purpose of this study was to determine the effects of relaxation and imagery on the sleep of critically ill adults. The study was an experimental clinical trial with random assignment to two groups. Analysis used repeated measures ANOVA. Thirty-six adults (17 males and 19 females) with a variety of physical diagnoses in three critical-care units in two large metropolitan hospitals were studied. Outcome measures were scores on a visual analog sleep scale, measured on three mornings. The intervention was a combination of relaxation and imagery, delivered on two evenings. All subjects' sleep improved over time. There were significant interaction effects between the intervention, gender, and time, with males' scores improving rapidly, and females' scores first dropping, then improving rapidly. A combination of relaxation and imagery is effective in improving the sleep of the critically ill adult, with men responding immediately to relaxation and imagery with improved sleep, and women taking more time to respond to the intervention.

Effects of progressive muscle relaxation on blood pressure and psychosocial status for clients with essential hypertension in Taiwan

This study examined the effect of progressive muscle relaxation (PMR) on blood pressure and psychosocial status in clients with essential hypertension. The study, which used a quasi-experimental design, recruited a convenience sample of 40 subjects from a hypertension outpatient clinic. Twenty subjects received PMR training once a week and practiced at home daily for 4 weeks. PMR training had an immediate effect, reducing pulse rate 2.35 beats/min, systolic blood pressure 5.44 mm Hg, and diastolic blood pressure 3.48 mm Hg. After 4 weeks of PMR training, further decreases in pulse rate (2.9 beats/min), systolic blood pressure (5.1 mm Hg), and diastolic blood pressure (3.1 mm Hg) occurred. PMR significantly lowered patients' perception of stress, and it enhanced their perception of health. PMR is beneficial for patients with essential hypertension, and nurses may use it to enhance their independent function as well as their quality of life.

A descriptive study of the interactive guided imagery experience

The purpose of this Study was to describe the experience of participating in Interactive Guided Imagery (IGI) from the perspective of clients. A qualitative descriptive design guided the research. Ten clients who had engaged in IGI, each with an R.N., IGI-certified practitioner, composed the sample. To explore participants' perceptions of their IGI experience, data were gathered through semistructured, in-depth interviews. Data analysis was carried out through data coding, categorizing, and subcategorizing; thematic synthesis; and structuring of relationships. Six primary themes emerged to compose the description of the experience of participating in IGI: the client's lived experience, use of a nonordinary state of consciousness, the guide, the guide-client relationship, influencing factors, and the results of IGI use. Based on the primary themes and their interrelationships, a model of the IGI experience was developed. The description and the model of the IGI experience provide the basis for further nursing knowledge development of the IGI modality.

Progressive muscle relaxation in cardiac rehabilitation: a pilot study

Learning to manage stress is an important lifestyle change for participants in cardiac rehabilitation programs. Progressive muscle relaxation (PMR) is one stress management approach that has produced positive benefits among different patient populations. The purpose of this study was to identify the effects of learning and practicing PMR in a population of cardiac rehabilitation patients. Blood pressure and heart rate data, and scores on the Spielberger State-Trait Anxiety Inventory (STAI) were collected from a treatment group and a control group of patients enrolled in phases II and III of cardiac rehabilitation. Analysis of the data revealed positive effects of PMR on the variables heart rate and state of anxiety. In addition, written evaluations of PMR from patients in the treatment group indicated a high degree of subjective satisfaction with PMR as a means to reduce stress in their lives.

Cardiac rehabilitation: a review of current developments

An overview is given of the current status of cardiac rehabilitation and its effects on morbidity and mortality. While there is an emphasis in most current programs upon physical exercise as an important autonomous risk factor for Coronary Heart Disease (CHD), there is at the same time a tendency in cardiac rehabilitation to go beyond mere physical exercise towards adding more multimodal psychoeducational modules in rehabilitation programs; those approaches are aimed at educating the patient about a less risky and healthier way of life. Such psycho-education is more and more aimed at the "toxic" aspects of negative emotions. The in-between classic Type A Behavior Pattern (TABP) might, in general, be less powerful in predicting later CHD morbidity or mortality than some specific emotional components of TABP, such as anger and hostility. The literature is reviewed as to risk factors and CHD and the role of negative affectivity in development and or maintenance of CHD. Approaches for modification are discussed against the background of their effectivity in cardiac rehabilitation. The recent Dutch guidelines, issued by the Dutch Heart Foundation, appear to incorporate many of the elements mentioned in the research literature on cardiac rehabilitation. On a scientific level they form an excellent audit to evaluate and to contour efficiently the until-now very heterogeneous field of cardiac rehabilitation.

Effect of relaxation therapy on cardiac events after myocardial infarction: a 5-year follow-up study

BACKGROUND

Evidence suggests that breathing and relaxation therapy may influence cardiac events in persons after acute myocardial infarction (MI). The authors studied the effects of breathing and relaxation therapy on rates of cardiac events and cost effectiveness in past MI patients.

METHODS

Patients (n = 156) were chosen randomly to receive either exercise training plus relaxation therapy (relaxation group; n = 76) or exercise training only (control group; n = 80). The occurrence of major cardiac events and cardiac rehospitalizations in the two treatment groups was compared.

RESULTS

At 5-year follow-up, 12 cardiac deaths had occurred, 5 in the relaxation group and 7 in the control group, reinfarction occurred in 10 and 12 patients, and cardiac surgery was performed in 2 and 11, respectively. In total, 15 (20%) and 26 (33%) patients, respectively, experienced at least one cardiac event (odds ratio [OR] for the relaxation group: 0.55, 95% confidence interval [CI] 0.29-1.05; adjusted for risk factors OR 0.52, 95% CI 0.28-0.99). Regarding all cardiac rehospitalizations, in the relaxation group, 30 patients (39%) had experienced 52 cardiac events, for which the patients were hospitalized for a total of 476 days. In the control group, 38 patients (48%) had experienced 78 cardiac events (OR 0.72; 95% CI 0.38-1.36), comprising 719 days of hospitalization. The total number of hospitalizations was reduced by 31% as a result of relaxation instruction.

CONCLUSIONS

In the long-term, the disease course after myocardial infarction is influenced favorably by giving relaxation therapy in addition to cardiac rehabilitation. The extra costs of the therapy are compensated by a decrease in hospitalization for cardiac problems.
