Optimal timing for initiation of biofeedback-assisted relaxation training in hospitalized coronary heart disease patients with sleep disturbances.

BACKGROUND: Clinical studies have shown that biofeedback-assisted relaxation positively influences the treatment outcomes of sleep disturbance. However, there are only few studies reporting the timing of relaxation training initiation, and the relationships between the timing of initiation and the effectiveness of relaxation remain unclear. OBJECTIVES: The aim of this study was to determine the optimal timing for initiating nurse-led biofeedback-assisted relaxation on hospitalized coronary heart disease patients with sleep disturbance. METHODS: An experimental pretest and repeated posttest design was used to compare the effectiveness of nurse-led biofeedback-assisted relaxation. A total of 128 patients with coronary heart disease were randomly assigned to 1 of 4 groups: morning group, night group, morning-night group, or control group. Outcome measures included self-report of sleep-related indicators, the scores of the Pittsburgh Sleep Quality Index (PSQI) and the Zung's Self-rating Anxiety Scale (SAS), and the dosage of sleep medication used. A 2-way analysis of variance and a simple effect test were used to analyze the differences among the 4 groups. RESULTS: No significant differences could be detected at baseline. Compared with the control group, the nurse-led biofeedback-assisted relaxation yielded a greater benefit for patients in the 3 intervention groups. Group and time factors (pretest-protest) could explain the variation in the effectiveness of this program (main effect P < .01). There were statistical differences among the groups: patients in the night group (FSOL = 33.15, P < .001; FTST = 17.99, P < .001; FSE = 10.26, P = .002; FPSQI = 27.38, P < .001; FSAS = 54.39, P < .001, respectively) and in the morning-night group (FSOL = 33.62, P < .001; FTST = 34.13, P < .001; FSE = 24.04, P < .001; FPSQI = 31.26, P < .001; FSAS = 73.93, P < .001, respectively) had slightly shorter sleep latency, experienced fewer awakenings, reported higher sleep quality, and used significantly fewer sleep medications than the morning group did (F = 32.97, P < .001). CONCLUSIONS: The timing of the initiation of nurse-led biofeedback-assisted relaxation was 1 of the factors affecting the effectiveness of relaxation. Relaxation training either at night or in the morning-night combination could effectively enhance sleep quality and decrease the need for of sleep medications in hospitalized patients with sleep disturbance.

The effect of music intervention in relation to gender during coronary angiographic procedures: a randomized clinical trial.

Several studies have evaluated music interventions prior and after coronary angiography and percutaneous coronary intervention (PCI), but there is no clear evidence showing that music has an effect on patients during these procedures. The purpose was to investigate the effects of music on anxiety, angina, pain, relaxation, and comfort in patients during angiographic procedures and to evaluate gender differences. The study was a four-armed, prospective randomized controlled trial included 240 patients undergoing coronary angiography and/or PCI. Patients were allocated to receive relaxing music, MusiCure or standard care during the procedure. Outcome measures were; puncture pain and the discomfort related to it, angina and the discomfort related to it, anxiety, experience of the sound environment, discomfort of lying still, and the doses of anxiolytics and analgesics during the procedure. No differences were found between the music and control groups regarding any of the trial endpoints or gender-related differences. The overall rating of the sound environment and feeling of relaxation was high. In conclusion, music intervention in patients undergoing angiographic procedures was highly feasible, but not effective in this study though the delivery of music went smoothly and did not disturb the examination and patients and staff alike looked favorably on it.

Cardiac rehabilitation coordinators' perceptions of patient-related barriers to implementing cardiac evidence-based guidelines.

BACKGROUND: Coronary heart disease remains the leading cardiovascular cause of mortality and morbidity globally. Implementing evidence-based guidelines after a coronary event is vital to prevent recurrence of an acute episode. However, various barriers to guideline implementation have been identified. OBJECTIVE: This article presents the perspective of cardiac rehabilitation (CR) coordinators regarding patient-related barriers to implementing the evidence-based guidelines after an acute cardiac event. METHODS: Twenty CR coordinators from 4 geographic regions of New South Wales, Australia, participated in the study. A semistructured interview using open-ended questions was used to obtain the CR coordinator's perspectives of the patient-related barriers to guideline implementation. Interviews were transcribed, and content analysis was undertaken. FINDINGS: The most frequently identified patient-related barriers were (a) coming to terms with a diagnosis of heart disease, (b) challenges in changing behavior, (c) having heart disease is costly, and (d) other personal barriers. CONCLUSIONS: Despite CR coordinators having positive attitudes toward implementing evidence-based guidelines, several patient-related barriers were identified that obstructed the implementation process. The findings have important implications for nursing practice in terms of directing efforts at increasing participation in CR and engaging commitment of the patient to behavior change. Changes to health service policies that address identified barriers could further facilitate the provision of evidence-based care to patients with coronary heart disease.

Cardiac disease and sexuality: implications for research and practice.

Many symptoms of cardiovascular disease can impact the patient's level of sexual desire. Nurses are in a position to assess sexuality of the cardiovascular patient and to provide a high degree of counseling on the subject; yet, nurses frequently complain that they lack the proper knowledge to provide this education and counseling. This article attempts to provide the necessary information regarding the physiologic effects of sexual intercourse on the heart, the role of sexuality in various types of cardiovascular disease, and the evidence-based nursing interventions needed to provide holistic care to patients with cardiovascular disease.

A critical analysis of the potential contribution of Orem's (2001) self-care deficit nursing theory to contemporary coronary care nursing practice.

BACKGROUND: Over the last three decades, nurse theorists have strongly advocated the use of conceptual models of nursing to guide nursing practice. Within coronary care units, conceptual model-based care has had inconsistent application and is currently challenged by contemporary approaches such as pathways of care. AIMS: This paper aims to critically analyze the use of Orem's self-care deficit nursing theory as a modus operandi to effectively meet the needs of hospitalized patients in coronary care. RESULTS: Although complex both in the language and construction, the self-care model , provides a comprehensive and holistic approach to the care of people in coronary care. CONCLUSIONS: This paper highlights the potential contribution the application of the self-care deficit nursing theory to the coronary care setting from a philosophical and practical perspective. Orem's conceptual model of nursing and current practice in coronary care units share certain similarities that render a useful model for use in practice. However, while it is recommended for consideration for use in both practice and educational settings, further empirical work is required in the area, together with realistic and practical application of the theory to practice in a way that embraces contemporary notions.

The perceptions of undergraduate student nurses of high-fidelity simulation-based learning: a case report from the University of Tasmania.

This paper reports a qualitatively informed curriculum research project in the three-year Bachelor of Nursing (BN) at the School of Nursing and Midwifery (SNM) at the University of Tasmania. The project investigated the perceptions of second year undergraduate nurses and their academic teachers of their experiences of high-fidelity simulation using the Laerdal Vital Sim Nursing Kelly and Nursing Anne technology(2) as part of their preparation for clinical practice. An associated curriculum benchmarking audit was also undertaken. A voluntary purposeful sample of students enrolled in a clinically-based practise unit(3) participated in the research, along with a small cohort of academic teachers. The results indicated that undergraduate nursing students value the opportunity to practice nursing activities in a safe environment prior to clinical placement. Students believed that simulation is an innovative strategy that promotes active learning and has great potential for developing clinical competence and increasing confidence prior to practise. The academic staff reported a similar belief about the potential of high-fidelity simulation in a case-based curriculum. The associated curriculum benchmarking audit provided evidence to support further integration of high-fidelity simulation in the undergraduate nursing program.

Reductionism and holism in coronary heart disease and cardiac nursing.

Reductionism and holism are two contrasting philosophies which provide scientific knowledge of disease processes, health dynamics and care interventions. While reductionism focuses on specific and perhaps narrow concepts, it enhances our in-depth knowledge of key health issues. Holism focuses on understanding how all the significant factors affecting the particular health issue are involved, so a more informed decision can be made about health intervention. This article explores the contribution each makes to our understanding of coronary heart disease (CHD) and to the preparation of nurses working in cardiac nursing. It proposes that pre- and post-registration nursing curricula reflect both reductionist and holistic approaches and therefore cardiac nurses are suitably trained to manage reductionist as well as holistic care for clients with CHD.

Effective anxiety treatment prior to diagnostic cardiac catheterization.

Music therapy, massage, guided imagery, therapeutic touch, and stress management instruction have been used successfully to decrease patient anxiety prior to diagnostic cardiac catheterization, providing better patient outcomes. The anxiety experienced among patients may have various causes, including not feeling cared about as an individual, too much waiting time before the procedure begins, and physical discomfort. This review determines nursing interventions that may effectively reduce anxiety prior to diagnostic cardiac catheterization.

Impact of a community-based multiple risk factor intervention on cardiovascular risk in black families with a history of premature coronary disease.

BACKGROUND: Black subjects with a family history of premature coronary heart disease (CHD) have a marked excess risk, yet barriers prevent effective risk reduction. We tested a community-based multiple risk factor intervention (community-based care [CBC]) and compared it with "enhanced" primary care (EPC) to reduce CHD risk in high-risk black families. METHODS AND RESULTS: Black 30- to 59-year-old siblings of a proband with CHD aged <60 years were randomized for care of BP > or =140/90 mm Hg, LDL cholesterol > or =3.37 mmol/L, or current smoking to EPC (n=168) or CBC (n=196) and monitored for 1 year. EPC and CBC were designed to eliminate barriers to care. The CBC group received care by a nurse practitioner and a community health worker in a community setting. The CBC group was 2 times more likely to achieve goal levels of LDL cholesterol and blood pressure compared with the EPC group (95% CI, 1.11 to 4.20 and 1.39 to 3.88, respectively) with adjustment for baseline levels of age, sex, education, and baseline use of medications. The CBC group demonstrated a significant reduction in global CHD risk, whereas no reduction was seen in the EPC group (P<0.0001). CONCLUSIONS: Eliminating known barriers may not be sufficient to reduce CHD risk in primary care settings. An alternative community care model that addresses barriers may be a more effective way to ameliorate CHD risk in high-risk black families.

Cardiac rehabilitation: goals, interventions and action plans.

Cardiac rehabilitation services are now well established in the UK. There is a growing evidence base for cardiac rehabilitation interventions but, despite this, there remains much variation in service models and delivery. The 'National Service Framework for Coronary Heart Disease' sets out goals for cardiac rehabilitation interventions based on lifestyle change; however, many people do not have access to cardiac rehabilitation towards menu-driven approaches, which may suit individual need more than a standardized approach. Nurses play a crucial role in the delivery of cardiac rehabilitation services and hold the necessary skills and expertise so to do. Future challenges to cardiac rehabilitation include developing increasingly patient-focused services across the boundaries of primary, secondary and social care, and increasing patient and public involvement in services.

Psychosocial antecedents of hostility in persons with coronary heart disease.

Although it is known that hostility precedes coronary heart disease (CHD), little is known about factors that influence the development and progression of hostile characteristics. The relations among hostility, self-esteem, self-concept, and psychosocial residual were conceptualized within the modeling and role-modeling theoretical framework and examined in a sample of 85 persons with CHD. There were significant associations between all variables. Regression analyses revealed that self-esteem, mistrust residual, isolation residual, and self-concept contributed significantly, accounting for 31% of the variation in hostility scores. These findings provide support for the belief that the development of hostility in persons with CHD is related to beliefs and attitudes about the self and others. Persons with self-esteem need deficits, and a subsequent build up of negative psychosocial residual, have poor self-concepts. This poor self-concept is hostile in nature and reflects a mistrust of others and a deep sense of isolation.

Overcoming barriers to better care.

Pharmacological developments and the shift of emphasis to primary care are just two developments that make it possible to widen access to cardiac services to more patients.

Cardiac therapy for men with coronary artery disease. The lived experience.

A phenomenological inquiry was conducted to uncover the lived experience of cardiac therapy for men with coronary artery disease in Northwest Ohio. Five men age 60 to 70 years were purposively selected to participate. Data obtained from individual audiotaped interviews were analyzed using Colaizzi's method. Eight major themes emerged: (a) feelings of fear and disbelief, (b) being aware of mortality, (c) losing control of self, (d) halting usual activities and future plans, (e) heightening awareness of spirituality and belief in a higher power, (f) resigning to accept external forces and required changes, (g) increasing sense of well-being, and (h) receiving a second chance and moving forward. This study makes valuable contributions to nursing by increasing awareness of actual lived experiences of cardiac therapy for men, offering direction for cardiac therapy programs to assist men with holistic lifestyle modifications that enable them to increase wellness, and serving as an impetus for further research.

Influence of psychosocial factors and biopsychosocial interventions on outcomes after myocardial infarction.

Management of the myocardial infarction patient may extend beyond the physiologic to include psychosocial factors that may adversely affect cardiac health. Psychosocial factors such as depression, coronary-prone behavior, hostility, social isolation, anxiety, anger, and stress are related to increased cardiac death and illness. Various interventions including cognitive-behavioral therapies, techniques that elicit the relaxation response, meditation, exercise, and increasing social networks, may play a role in improving health outcomes. This article explores the relationship of these psychosocial factors to cardiac health and proposes a biopsychosocial model of care.

Developing and implementing a Healthy Heart program for women in a parish setting.

Designed for implementation in a parish setting, the "Hearts To God" project integrates spirituality, stewardship, and wholeness into a cardiovascular health promotion program. This program fills a health education void regarding cardiovascular disease and women. The program and accompanying manual incorporate heart healthy education with a spirituality message to encourage behavior change. It can be adapted to suit the educational context and adult population. Exercises included in the manual enable women to assess, develop, and evaluate their own plan for heart health. Participants found the program to be relevant.

Healing through integration: promoting wellness in cardiac rehabilitation.

This case study illustrates the basic life processes, transitions, and meanings of a woman with diagnosed coronary artery disease who participated in an innovative outpatient program of cardiac rehabilitation. Data gathering and analysis were accomplished using the phenomenologic procedures outlined by Spiegelberg and van Manen. A formulated structure, healing through integration, was generated from the interpretation of case study data, as well as the data of 15 other adult patients who participated in a program of outpatient cardiac rehabilitation. This structure provides a framework for nursing assessment and the implementation of relevant mind, body, social, spiritual, and behavioral interventions designed to assist individuals in integrating health-enhancing behaviors and recovery following a cardiac health crisis.
