Lifestyle Changes Following Acute Myocardial Infarction: Patients Perspectives

Mental Health Factors and Lifestyle Adherence After Myocardial Infarction: An Integrative Review

BACKGROUND

Engaging in healthy lifestyle behaviors following myocardial infarction can improve clinical health outcomes and lower cardiovascular risk factors among patients. However, adhering to a healthy lifestyle after having a myocardial infarction can be challenging, especially for those experiencing poor mental health.

OBJECTIVE

Based on a conceptual model derived from Lazarus and Folkman's Theory of Stress and Coping and the Health Belief Model, this integrative review focuses on mental health factors associated with adherence to healthy lifestyle behaviors post-myocardial infarction.

METHODS

Whittemore and Knafl's integrative review method was used to search and select relevant literature from the EMBASE, PubMed, CINAHL, Scopus, and PsycINFO databases between 2013 and 2023.

RESULTS

A total of 35 articles were included in the review. Based on the Johns Hopkins Nursing Evidence-Based Practice Model criteria, 34 studies were of good quality (B). Mental health factors related to healthy lifestyle behaviors after myocardial infarction included the following: (1) personality factors and coping (eg, neuroticism, agreeableness, and optimism); (2) psychological symptoms (i.e., depression, anxiety, and fear); (3) appraisal (ie, illness perception); (4) health beliefs (ie, susceptibility, severity, benefits, barriers, cues to action, and self-efficacy); and (5) motivation. Social support and demographic characteristics were also related to adherence to healthy lifestyle behaviors.

CONCLUSIONS

This review highlights the role of mental health factors in adhering to healthy lifestyle behaviors among persons with myocardial infarction. Comprehensive theoretically based approaches are needed to develop future interventions for promoting healthy lifestyle behaviors in individuals post-myocardial infarction.

Implementation of a value-based approach for older people who have suffered an acute myocardial infarction: study protocol

Introduction

Due to the rapid aging of the global population, new approaches are required to improve the quality of life of older people and to reduce healthcare system expenditures. One of the approaches that can be used is value-based healthcare. This article describes a value-based solution for older people who have suffered a myocardial infarction.

Methods

This solution combines the work of healthcare professionals and informal caregivers and the use of modern and user-friendly technologies to support the achievement of patients' values. Patients older than 65 years who have suffered a myocardial infarction will be divided into control and intervention groups within a pre-post-controlled design research study. Members of the intervention group will be provided with a personalized plan developed by healthcare professionals and based on the results from the baseline questionnaire.

Discussion

Two ValueCare digital solution components will be developed: a mobile application for the participants and a web platform for the professionals, researchers, and informal caregivers. Together with smartwatches, which will track important health aspects, and applications, this approach would enable older people to improve their health through correct lifestyle choices and their professional and informal caregivers to track their progress. With the use of the described technology and the multidisciplinary approach, the unmet needs and values of participants could be achieved. Using this approach, it could be possible to reduce overall healthcare expenses through the active involvement of both older people and their informal caregivers through a shared decision-making process with healthcare professionals.

Risk factors for in-patient myocardial infarction following total hip arthroplasty

Purpose

The aim of this study was to identify potential risk factors for myocardial infarction immediately following total hip arthroplasty.

Methods

The 2016-2019 Nationwide Inpatient Sample database was used to identify patients who underwent primary total hip arthroplasty (THA) and suffered a myocardial infarction (MI). Patient data including demographics, admission, and comorbidities were recorded. Univariate analysis and subsequent multivariate logistic regression were performed to determine which circumstances affected the odds of MI.

Results

A total of 367,890 patients were identified for THA with 142 of those also having a myocardial infarction. Those who experienced an MI had increased length of stay, total charges, and generally negative dispositions compared to their non-MI counterparts (p < 0.001). Through regression analysis, factors that increased the odds of MI included older age [odds ratio (OR) 1.59, 95 % confidence interval (CI) 1.49-1.70], a female sex (OR 1.46, 95 % CI 1.37-1.55), previous coronary artery bypass graft (OR 1.20, 95 % CI 1.01-1.43), obesity (OR 1.12, 95 % CI 1.04-1.21), colostomy (OR 2.07, 95 % CI 1.21-3.56), and Parkinson's disease (OR 1.48, 95 % CI 1.13-1.95). Factors that decreased that risk included elective admission (OR 0.21, 95 % CI 0.19-0.22) and a tobacco related disorder (OR 0.69, 95 % CI 0.63-0.76).

Conclusions

Patient risk for myocardial infarction following total hip arthroplasty varies in part based on their background and comorbidities. These findings can be used to better recognize those who should receive further precautions and tailor proper treatment strategies for THA.

The effect of caregivers' care burden and psychological resilience on the psychosocial adjustment of patients with open heart surgery in Turkey

This cross-sectional study investigated the effect of caregivers' care (n = 100) burden and psychological resilience on the psychosocial adjustment of patients (n = 100) with open heart surgery. Patients had poor psychosocial adjustment. Caregivers who felt incompetent in providing care had a higher care burden and a lower psychological resilience than those who did not. In addition, patients whose caregivers had higher resilience and lower burden of care had better psychosocial adjustment. The results of this study compellingly demonstrate the importance and necessity of supportive and preventive clinical social work interventions to enhance patients' adaptation to a new lifestyle and compliance with treatment during the cardiac rehabilitation process, and reduce the burden on caregivers.

Polysaccharides, proteins, and synthetic polymers based multimodal hydrogels for various biomedical applications: A review

Nature-derived or biologically encouraged hydrogels have attracted considerable interest in numerous biomedical applications owing to their multidimensional utility and effectiveness. The internal architecture of a hydrogel network, the chemistry of the raw materials involved, interaction across the interface of counter ions, and the ability to mimic the extracellular matrix (ECM) govern the clinical efficacy of the designed hydrogels. This review focuses on the mechanistic viewpoint of different biologically driven/inspired biomacromolecules that encourages the architectural development of hydrogel networks. In addition, the advantage of hydrogels by mimicking the ECM and the significance of the raw material selection as an indicator of bioinertness is deeply elaborated in the review. Furthermore, the article reviews and describes the application of polysaccharides, proteins, and synthetic polymer-based multimodal hydrogels inspired by or derived from nature in different biomedical areas. The review discusses the challenges and opportunities in biomaterials along with future prospects in terms of their applications in biodevices or functional components for human health issues. This review provides information on the strategy and inspiration from nature that can be used to develop a link between multimodal hydrogels as the main frame and its utility in biomedical applications as the primary target.

Lifestyle-related habits and factors before and after cardiovascular diagnosis: a case control study among 2,548 Swedish individuals

BACKGROUND

Healthy lifestyle habits are recommended in prevention of cardiovascular disease (CVD). However, there is limited knowledge concerning the change in lifestyle-related factors from before to after a CVD event. Thus, this study aimed to explore if and how lifestyle habits and other lifestyle-related factors changed between two health assessments in individuals experiencing a CVD event between the assessments, and if changes varied between subgroups of sex, age, educational level, duration from CVD event to second assessment and type of CVD event.

METHODS

Among 115,504 Swedish employees with data from two assessments of occupational health screenings between 1992 and 2020, a total of 637 individuals (74% men, mean age 47 ± SD 9 years) were identified having had a CVD event (ischemic heart disease, cardiac arrythmia or stroke) between the assessments. Cases were matched with controls without an event between assessments from the same database (ratio 1:3, matching with replacement) by sex, age, and time between assessment (n = 1911 controls). Lifestyle habits included smoking, active commuting, exercise, diet, alcohol intake, and were self-rated. Lifestyle-related factors included overall stress, overall health (both self-rated), physical capacity (estimated by submaximal cycling), body mass index and resting blood pressure. Differences in lifestyle habits and lifestyle-related factors between cases and controls, and changes over time, were analysed with parametric and non-parametric tests. Multiple logistic regression, OR (95% CI) was used to analyse differences in change between subgroups.

RESULTS

Cases had, in general, a higher prevalence of unhealthy lifestyle habits as well as negative life-style related factors prior to the event compared to controls. Nevertheless, cases improved their lifestyle habits and lifestyle factors to a higher degree than controls, especially their amount of active commuting (p = 0.025), exercise (p = 0.009) and non-smoking (p < 0.001). However, BMI and overall health deteriorated to a greater extent (p < 0.001) among cases, while physical capacity (p < 0.001) decreased in both groups.

CONCLUSION

The results indicate that a CVD event may increase motivation to improve lifestyle habits. Nonetheless, the prevalence of unhealthy lifestyle habits was still high, emphasizing the need to improve implementation of primary and secondary CVD prevention.

Adjustment Mechanisms in the Acute Phase of Myocardial Infarction in Men

AIM

Stress and Coping Model and Post-Traumatic Growth Theory indicate adjustment procedures concepts after a crisis. The objective of this study was to assess the relationships between causal attributions, coping strategies and post-traumatic growth in male patients with acute myocardial infarction and variable cardiac function severity.

METHODS

Seventy-eight male patients surviving a myocardial infarction, were divided into two sub-groups based on left ventricular ejection fraction measurements [Group A (left ventricular ejection fraction: <45%, n = 34), Group B (left ventricular ejection fraction: ≥45%, n = 44)] and were interviewed after the acute phase of myocardial infarction, on the last day of their coronary unit stay. Medical data was obtained from their medical records. Causal Attributions' List, Coping Orientation to Problems Experienced and Post-Traumatic Growth Inventory were used.

RESULTS

Causal attributions were found to be related to active coping, emotional support, religious coping and self-blame in both groups. Planning, positive reinterpretation and active coping were the strategies associated positively with most of the post-traumatic inventory subscales in total data analyses.

CONCLUSIONS

Diverse coping strategies were associated with posttraumatic growth factors. It is important to assess adjustment mechanisms in the acute phase of myocardial infarction. A tailored scheme therapy, considering patient's needs, has to be planned.

Experience and Perceptions among Older Outpatients after Myocardial Infarction following an Exercise Intervention: A Qualitative Analysis from the PIpELINe Trial

Traditional cardiac rehabilitation (CR) programs effectively improve physical performance and outcomes after myocardial infarction (MI). However, older patients are less likely to participate in such programs. The aim of this qualitative analysis was to investigate experiences and perceptions of cardiac outpatients enrolled in an innovative and exercise-based CR program and to identify possible barriers to improving adherence and quality of life. Semi-structured interviews were conducted on a sample of 31 patients (84% male; age 76 ± 6 years) from the Physical Activity Intervention in Elderly after Myocardial Infarction (PIpELINe) trial, after about six months of the event. Three main themes were identified: Personal feelings after the event; lifestyle change and perception of barriers; and relationships with familiars. Participants perceived sensations of fear at the time of their diagnosis and showed awareness of the importance of following specific health suggestions. They reported a significative change in previous habits and highlighted the need for periodic controls. Few of them felt insecure in carrying out daily activities or practicing exercise and reported an unnecessary protection from the family members. These findings will provide valuable insights for the development of a more feasible patient-centered CR model of intervention.

Influence of Comprehensive Lifestyle Intervention (LSI) Program on Health, Fatigue, and Quality of Life in Middle-Aged Women

Background

Middle age is one of the most important times in a woman's life, and it is a time when multiple changes occur that affect the body and health. The study aimed to investigate the efficacy of a comprehensive lifestyle intervention (LSI) program, including stress management, on middle-aged women's physical, physiological, and mental health.

Methods

A total of 40 middle-aged women participated in a short-term LSI program, nutrition, exercise, and mental and physical management with various experiential activities. Physical measurements, biochemical indicators, stress hormones, chronic fatigue, and quality of life indicators were evaluated to interpret the clinical efficacy of the program.

Results

LSI program significantly improved satisfaction and quality of life in participants. Total chronic fatigue scores reduced significantly compared to scores before the start of the program. Moreover, fat mass and body fat were reduced without loss of muscle mass. Further, blood pressure and triglyceride levels significantly decreased after completing the LSI program. However, changes in stress hormone levels remained insignificant.

Conclusion

Adoption of LSI in middle-aged women demonstrated positive implications of the program. LSI efficiently regulates body fat, fat mass, fatigue, hypertension, and triglyceride levels which play a critical role in determining the quality of life. Thus, the LSI program could spread healthy lifestyles among middle-aged women.

Promotion and maintenance of physically active lifestyle in older outpatients 2 years after acute coronary syndrome

AIMS

To examine long-term changes in lifestyle and exercise capacity of older patients hospitalized for acute coronary syndrome (ACS) involved in an innovative centre- and home-based exercise-based secondary prevention program.

METHODS

A sample of 118 patients with ACS (age 76 [72-80] years) was analysed. Long-term changes in self-reported weekly leisure-time physical activity (wLTPA), walking speed (WS), and estimated cardiorespiratory fitness (eCRF, VO₂peak, mL/kg/min) were the outcome variables. The program consisted of seven individual on-site sessions including motivational interviewing to reach exercise goals. Exercise prescription was based on the results of a standardized moderate and perceptually regulated treadmill walk to estimate VO₂peak. wLTPA, WS, and eCRF were assessed at 1 (baseline), 2, 3, 4, 6, 12, and 24 months after discharge.

RESULTS

87, 76, and 70 patients completed follow-up at 6, 12, and 24 months, respectively. wLTPA significantly increased during the follow-up period (median METs/H/week 2.5, 11.2, 12.0, and 13.4 at baseline, 6, 12, and 24 months, respectively; P < 0.0001). At baseline, 18% of the sample met the current international guidelines for physical activity, while 75%, 70%, and 76% of them met the recommended values at 6-, 12-, and 24-month follow-up sessions, respectively. These results were associated with increasing median WS (2.9 ± 1.0, 4.3 ± 1.2, 4.5 ± 1.1, 4.5 ± 1.2 km/h, respectively, P < 0.0001), and VO₂peak (16.5, 21.4, 21.1, 21.3 mL/kg/min, respectively, P < 0.0001).

CONCLUSIONS

This early, individualized exercise intervention improved long-term adherence to a physically active lifestyle, walking capacity, and eCRF in older patients after ACS. Larger studies are needed to confirm short- and long-term clinical benefits of this intervention.

Active Lifestyle Post First Myocardial Infarction: A Comparison between Participants and Non-Participants of a Structured Cardiac Rehabilitation Program

Following myocardial infarction (MI), impaired physical, mental, and cognitive functions can reduce participation in the community and diminish quality of life. This study aims to assess active lifestyle participation and functional performance in patients who were participants and non-participants in cardiac rehabilitation. A total of 71 patients were recruited, 6-10 months after the MI event; 38 chose to participate in a cardiac rehabilitation (CR) program, and 33 did not (NCR). Participation and activity patterns in instrumental activities of daily living, as well as physically demanding leisure activities and social activities, were evaluated using the Activity Card Sort (ACS). Hand grip force and timed up and go (TUG) were tested. A total of 74% of the CR group met physical activity recommendations and only 34% continued to smoke, compared to 39% and 71% in the NCR group, respectively. The CR group, compared to the NCR group, had higher levels of daily activity, social leisure, and physically demanding leisure activities (p ≤ 0.001). Null differences between the NCR and CR groups were observed in grip strength and the TUG tests. The study highlighted community participation after MI. Based on a comparison between the groups, the study implies that patients choosing to participate in CR retained higher community participation levels and had better self-management of cardiovascular risk factors.

One size does not fit all: A qualitative study exploring preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease

Aim

To explore preferences and barriers towards the design of a loneliness reduction intervention in patients treated for coronary heart disease who experience loneliness.

Design

A qualitative study using patient involvement methodology.

Methods

Seventeen patients participated in either focus groups or individual interview sessions. The interview guide was based on patient involvement methodology. Interviews were analysed using deductive content analysis.

Results

Four overall findings emerged as follows: (a) An intervention involving a social network member must comply with patients perceived social norms; (b) An intervention involving a peer provides benefits from reciprocity and shared experiences, but also requires surplus mental energy; (c) The history of an existing relationship can act as both provider and barrier for confidentiality and (d) Start‐up, timeframe and structure of the intervention should be individually tailored to the patient's preferences. Findings illuminated preferences and barriers towards the design of a loneliness reduction intervention in patients with coronary heart disease.

Life After Myocardial Infarction: A Qualitative Study on Experiences of Kurdish Patients Affected by Iran-Iraq War

Background

Coronary artery disease (CAD) is a major cause of death globally. Myocardial infarction (MI) secondary to CAD affects patients’ quality of life and their lifestyle. The experience of war can affect people’s perception of phenomena. Given the scarcity of information in Kurdish patients with MI, the current study was designed to explore the lived experiences of individuals after MI in Kurdish patients affected by Iran–Iraq war.

Methods

This interpretive-phenomenological study was conducted on eleven patients with MI (9 men, 2 women) at Imam Ali Hospital, Center for Heart Diseases, in Kermanshah, Iran, considering MI as a phenomenon. Data was collected by a semi-structured interview and analyzed using the Van Mannen method. We employed the Lincoln and Guba criteria to examine the credibility, confirmability, dependability, and transferability of data. MAXQDA software was used for data management. We followed the COREQ checklist to ensure the rigor of our study

Results

Four themes and ten sub-themes were emerged as (1) “changes in the quality of life” including (a) negative physical outcomes, (b) mental effects, (c) social support, (d) adopting healthy behaviors, (e) increase or decrease in self-efficiency, (f) previous experience, and (g) developing future behaviors; (2) “bodily perceptions and medical care” including (a) medical care: saving or terminating life?, (b) a new message from the heart; (3) “returning to spirituality against death” including (a) spirituality as a guiding principle, (b) accepting death as an eventual destiny; and (4) denial.

Conclusion

The results suggest that MI could change the quality of physical and mental health of the person, anywhere from deterioration to full recovery. Furthermore, the influence of spirituality and previous experience of war to overcome the complications of MI has been discussed, leading to either acceptance or denial of MI, and the consequences.

Factors that influence adherence to treatment plans amongst people living with cardiovascular disease: A review of published qualitative research studies

BACKGROUND

Treatment plan adherence is recognized as a worldwide health issue, particularly important in the management of cardiovascular patients. Healthcare professionals are the primary sources of information and support for people diagnosed with CVD and those who have experienced a cardiac event, yet we know little about how healthcare professionals contribute to the process of adherence to treatment plans that aim to prevent and/or reduce disease and adverse events. Qualitative evidence that explores factors that influence adherence to treatment plans is limited.

OBJECTIVE

This systematic review identified and synthesised the best available evidence on factors that influence adherence to treatment plans amongst people living with cardiovascular disease.

DESIGN

Systematic review and qualitative synthesis.

METHODS

Data were collected from Medline, Web of Science, CINAHL, PsychINFO, Embase- Non-Medline, Scopus, Cochrane Library, ProQuest Central (Grey Literature). Pre-defined keywords and MeSH terms were used to identify qualitative methods English-language studies published between 2001 and 2018. Quality appraisal of each paper was completed using the JBI Critical Appraisal Checklist and two reviewers extracted the data independently.

RESULTS

Twenty-two articles were included. Eight key themes were identified that related to facilitators and barriers to adherence to treatment plans. Facilitators were identified as engaging in exercise, having support and mentorship, lifestyle modification, and the perceived value of taking medication. Barriers were identified as a perceived lack of support, concerns about taking medication, and lack of engagement in exercise and lifestyle changes.

CONCLUSIONS

The findings highlight the factors that support adherence and healthcare professionals can build on also the areas that can be targeted to support and improve adherence to treatment plans. Nurses can play an important role in enhancing the provision of information pre hospital discharge and support in the community on taking medication, the value of physical activity and dietary changes.

Experiences of Undergoing Enhanced External Counterpulsation in Patients With Refractory Angina Pectoris: A Qualitative Study

BACKGROUND

Enhanced external counterpulsation (EECP) is a noninvasive treatment recommended for patients with refractory angina pectoris (RAP), which generally includes 35 one-hour sessions over 7 weeks. No study has described how patients experience the time before, during, and between sessions, as well as the time after EECP treatment.

OBJECTIVE

The aim of this study was to describe how patients with RAP experience EECP treatment.

METHODS

Semistructured interviews took place with 15 strategically selected patients (11 men, 58-91 years old) who had finished 7 weeks of EECP at the 2 existing EECP clinics in Sweden. Data were analyzed using inductive qualitative content analysis.

RESULTS

The results were divided into 4 content areas, each comprising 3 categories: (1) experiences before EECP was initiated comprised uncharted territory, being given a new opportunity, and gain insight; (2) experiences during EECP sessions comprised physical discomfort, need of distraction, and sense of security; (3) experiences between EECP sessions comprised physical changes, socializing, and coordinating everyday life; and (4) experiences after 1 course of EECP treatment comprised improved physical well-being, improved mental well-being, and maintaining angina in check.

CONCLUSIONS

Enhanced external counterpulsation was perceived as an unknown treatment option among these patients with RAP. Nurses should emphasize education before and during treatment based on individualized care needs to improve knowledge and treatment experience, as well as prevent discomfort. There is a great need to increase the awareness of EECP among healthcare professionals because it can improve the life situation for patients with RAP.

Participants' Perspectives of a Primary Exercise-Based Prevention Program for Cardiac Patients: A Prepost Intervention Qualitative Case Study

Perseverance in exercise-based, cardiovascular disease prevention programs is generally very low. The purpose of this case study is to understand the experience of participants enrolled in a 6-month primary and secondary exercise-focused, cardiovascular disease prevention out of hospital program. Ten participants were interviewed about their experiences at entry and after it ended 6 months later to understand the facilitators and difficulties encountered by participants in such exercise programs. Four out of ten participants completed the 6-month program. The six participants who left the program accepted to contribute to the postprogram interview. The results showed that the four participants who persevered in the program became aware of cardiac risk factors and their conditions were willing to make changes in their lifestyles to reach their objectives, felt a strong perception of self-efficacy, and felt like they belonged in the program. Both persevering and nonpersevering participants experienced many episodes of discouragement during the program and faced many barriers that interfered with their progress. Suggestions to help coping with these barriers while reinforcing self-efficacy and the sentiment of belonging are discussed.

Patients' Experiences of Cardiovascular Health Education and Risk Communication: A Qualitative Synthesis

Coronary heart disease (CHD) has no cure, and patients with myocardial infarction are at high risk for further cardiac events. Health education is a key driver for patients' understanding and motivation for lifestyle change, but little is known about patients' experience of such education. In this review, we aimed to explore how patients with CHD experience health education and in particular risk communication. A total of 2,221 articles were identified through a systematic search in five databases. 40 articles were included and synthesized using thematic analysis. Findings show that both "what" was communicated, and "the way" it was communicated, had the potential to influence patients' engagement with lifestyle changes. Communication about the potential of lifestyle change to reduce future risk was largely missing causing uncertainty, anxiety, and, for some, disengagement with lifestyle change. Recommendations for ways to improve health education and risk communication are discussed to inform international practice.

Health literacy in persons at risk of and patients with coronary heart disease: A systematic review

BACKGROUND

Health literacy (HL) plays a crucial role in the maintenance and improvement of individual health. Empirical findings highlight the relation between a person's HL-level and clinical outcomes. However, the role of HL in persons at risk for coronary heart disease (CHD) and patients with CHD has not been researched conclusively.

OBJECTIVE

The aim of this study was to review systematically the current evidence on HL, its dimensions (access to, understanding, appraisal and apply of health-related information), and its important influencing factors, with regard to CHD risk.

METHOD

We used a mixed-methods approach. Eligible articles needed to employ a validated tool for HL or mention the concept and at least one of its dimensions. After the screening process, 14 quantitative and 27 qualitative studies were included and referred to one or more dimensions of HL. Six observational studies measured HL with a validated tool.

RESULTS

Findings suggest that patients with lower HL feel less capable to perform lifestyle changes, exhibit fewer proactive coping behaviors, are more likely to deny CHD, are generally older, are less often employed, have lower educational levels and lower socioeconomic status, experience faster physical decline, and use the healthcare system less, compared to patients with higher HL. Barriers to HL include inadequate provision of information by health providers, lack of awareness of the risk factors for CHD, perceived impairment of quality of life due to lifestyle changes, and negative experiences with the healthcare system. Facilitators include a good patient-physician relationship based on good communicative competences of health providers.

CONCLUSIONS

The concept of HL yields a promising potential to understand the process from obtaining information to actual health behavior change, and the results clearly indicate the need for more systematic research on HL in CHD patients and persons at risk.

Estudio longitudinal de la recuperación psicosocial tras un infarto agudo de miocardio

En esta investigación se quería indagar si la recuperación y el ajuste psicológicos después de un infarto agudo de miocardio (IAM) se relacionan con la sobreprotección y el apoyo social recibidos, así como esclarecer si estas variables tienen impacto en los niveles de depresión, ansiedad y calidad de vida. Además, se quería averiguar si la sobreprotección ralentiza la reincorporación al trabajo y cómo ésta afecta a la autoeficacia. Las cuestiones planteadas fueron evaluadas en un estudio longitudinal de tres fases (convalecencia hospitalaria y seguimiento a los 4 y 18 meses) en una muestra de 50 pacientes ingresados por IAM. Se emplearon instrumentos para registrar la sobreprotección, el apoyo social, la ansiedad, la depresión, la calidad de vida y la autoeficacia. Los resultados de la primera fase mostraron una relación significativa entre sobreprotección y depresión y entre ésta y una peor calidad de vida. En la segunda, la sobreprotección se relacionaba con la depresión y la calidad de vida, pero solamente cuando producía un descenso en la autoeficacia. Además, quienes no se habían reincorporado al trabajo informaban de recubir mayor sobreprotección. A los 18 meses (tercera fase), la sobreprotección predecía únicamente la ansiedad. En conclusión, la sobreprotección y el descenso en autoeficacia derivado de ella, constituyen variables de ajuste a la enfermedad, en términos de depresión, calidad de vida y ansiedad, mientras que el apoyo social no mostró tener el peso esperado inicialmente.

Development and Validation of a Scale to Measure Fear of Activity in Patients With Coronary Artery Disease (Fact-CAD)

OBJECTIVE

To develop and validate a scale to measure fear of activity in patients with coronary artery disease.

DESIGN

Psychometric study.

SETTING

Outpatient cardiology clinics.

PARTICIPANTS

The scale was applied to patients who had myocardial infarction, coronary artery bypass grafting, or percutaneous coronary intervention within the last 12 months (N=250).

INTERVENTIONS

A scale for fear of activity in patients with coronary artery disease (Fact-CAD) was created through semistructured focus group interviews with patients. Face and content validity of Fact-CAD was verified.

MAIN OUTCOME MEASURES

Psychometric analysis included model fit, unidimensionality, reliability, local dependency, differential item functioning, and external construct validity. Analyses were performed using the Rasch Analysis Model.

RESULTS

Fact-CAD scale was a reliable (high Person Separation Index of 0.89) and valid (unidimensional, no misfit, local independency supported, no residual correlations) measure of fear of activity. Three items showed differential item functioning according to employment status, marital status, and angina pectoris, which were not assigned as real item bias by experts and remained in the model.

CONCLUSION

Fact-CAD was supported by Rasch analysis as a psychometrically valid scale to evaluate fear of activity in patients with coronary artery disease.

Social Support, Self-Efficacy, and Helplessness Following Myocardial Infarctions

Numerous factors impact patient recovery following an acute myocardial infarction (AMI). Negative emotional outcomes, such as learned helplessness, are predictors of mortality following AMI, though little is known about these relationships. The purpose of this study was to examine the relationships between social support and self-efficacy with learned helplessness in individuals post-AMI. Using a descriptive cross-sectional design, subjects with a diagnosed AMI within 12 months were recruited. Standardized instruments were used to evaluate social support and self-efficacy and their impact on learned helplessness. A statistically significant, direct relationship was found between social support and self-efficacy, and learned helplessness, suggesting that individuals with better social support and self-efficacy experience less learned helplessness within the first year following an AMI. In developing post-AMI treatment plans, health care staff need to consider encouraging a patient's supportive social network and self-efficacy as meaningful interventions against negative emotional outcomes.

Health behavior practice among understudied Chinese and Filipino Americans with cardiometabolic diseases

Lifestyle modification and health behavior practice among the individuals with cardiometabolic diseases (CMD) are important for secondary prevention and disease control. This study was designed to investigate and compare health behavior practices among Chinese and Filipino Americans with CMD. Three hundred seventy-four Asian Americans (211 Chinese and 163 Filipino) who reside in the greater Philadelphia region and had either CMD or no identified disease were included in the study. Information on smoking, alcohol intake, physical activity, and salt and sweets consumption was collected, as well as demographic and acculturative characteristics. Of the 374 participants, 241 (64.4%) had CMD and 133 (35.6%) had no identified disease. The majority of Chinese and Filipino Americans with CMD failed to meet the dietary and physical activity guidelines, and only a small percentage of them restricted their amount of salt added to food and amount of sweets consumption. Compared to participants with no disease, Chinese participants with CMD were more likely to "never" add salt to food (AOR 4.42 compared to "frequently"). Filipino Americans with CMD were less likely to be those who "never" consume sweets than those who frequently consume sweets (AOR = 0.12). Among the participants with CMD, Chinese participants with CMD were less likely to restrict drinking (AOR 0.11) than Filipinos with CMD. The findings suggest that tailored interventions for Chinese and Filipino Americans with CMD should be developed to enhance their compliance to behavioral guidelines to prevent further disease progression and complications.

To change or not to change - That is the question: A qualitative study of lifestyle changes following acute myocardial infarction

Objective The purpose of this study was to investigate key factors related to lifestyle changes following acute myocardial infarction (AMI) by eliciting survivors' subjective needs for, attitudes towards and experiences with behaviour changes in their everyday life to improve future interventions promoting lifestyle changes. Methods Semi-structured interviews were conducted with 21 individuals who had recently experienced an AMI. The interviews were audio-recorded and transcribed verbatim. The data were analysed using qualitative content analysis. Results The data analysis revealed that lifestyle changes following AMI are influenced by a combination of individual (physical and psychological) and social factors that can be grouped into facilitators and barriers. The interviews indicated the need for more personalised information regarding the causes and risk factors of illness, the benefits of lifestyle changes and the importance of including significant others in lifestyle advice and education and of individualising support. Discussion Lifestyle change is a continuous process that is not completed within a few months after a cardiac event. Considering the identified themes when developing interventions to promote lifestyle changes following AMI may enhance the effectiveness and sustainability of such interventions.

Factors associated with anxiety and depression in hospitalized patients with first episode of acute myocardial infarction

Introduction

Evaluation of anxiety and depression in cardiac patients is an area of nursing practice that is frequently neglected. The aim of the study was to explore anxiety and depression in hospitalized patients with their first episode of acute myocardial infarction.

Material and methods

The study sample included 148 hospitalized patients who had a first episode of acute myocardial infarction. Data collection was performed by the interview method using a specially designed questionnaire which included socio-demographic, clinical and other patients’ characteristics as well as the Hospital Anxiety and Depression Scale (HADS) to assess patients’ levels of anxiety and depression.

Results

Analysis of data showed that 52% and 38% of participants had high levels of anxiety and depression, respectively. Furthermore, anxiety levels revealed a statistically significant association with anxiolytics (p = 0.005) and antidepressant medication (p = 0.026) in hospital, the belief that they will face difficulties in relations with the social and family environment (p = 0.009 and p = 0.002, respectively) and whether they considered themselves anxious (p = 0.003). Depression was statistically significantly associated with education level (p = 0.001), profession (p = 0.007), antidepressant medication in hospital (p ≤ 0.001), patients’ relations with nursing staff (p = 0.019) and patients’ belief that they will face difficulties in relations with the social and family environment (p ≤ 0.001 and p ≤ 0.001, respectively).

Conclusions

The results showed that socio-demographic and clinical characteristics should be taken into serious consideration when exploring anxiety and depression in patients with a first episode of acute myocardial infarction in order to implement appropriate interventions.

Evaluating Motivational Interviewing in the Physician Assistant Curriculum

PURPOSE

Motivational interviewing (MI) is an evidence-based technique that enables clinicians to help patients modify health behaviors. Although MI is an essential tool for physician assistants (PAs), the extent to which it is addressed in PA curricula in the United States is unknown. This study is a comprehensive description of MI education in PA programs in the United States.

METHODS

Data are from the 2014 Physician Assistant Education Association Annual Program Survey. Descriptive statistics were conducted on de-identified data from all 186 PA programs in the United States.

RESULTS

Of the 186 PA programs surveyed, 72.58% (n = 135) reported at least one course providing MI training. Availability of courses providing training in skills essential to the MI process varied. Having a course with verbal communication training was most frequently endorsed, and having a course with training in developing discrepancy was least frequently endorsed. The most popular teaching modality was lecture (84.95%, n = 158), whereas only 41.40% (n = 77) and 58.60% (n = 109) reported role play with evaluation and standardized patient exercises with evaluation, respectively.

CONCLUSIONS

More than 70% of programs included at least one course in their curriculum that provided training in MI, suggesting that PA programs recognize the importance of MI. Instruction in change talk was not provided in nearly half of the programs. Role-play and standardized patient exercises with evaluation were underused methods despite their proven efficacy in MI education. As the first comprehensive benchmark of MI education for PAs, this study shows that although most programs address MI, opportunities exist to improve MI training in PA programs in the United States.

A phenomenological construct of caring among spouses following acute coronary syndrome

The aim of this study was interpret the existential construct of family caring following Acute Coronary Syndrome. Family support is known to have a positive impact on recovery and adjustment after cardiac events. Few studies provide philosophically-based, interpretative explorations of carer experience following a spouse's ischaemic event. As carer experiences, behaviours and meaning-making may impact on the quality of the support they provide to patients, further understanding could improve both patient outcomes and family experience. Fourteen spouses of people experiencing Acute Coronary Syndrome in Sydney, Australia were engaged in a single, semi-structured interview. Interviews were audio-recorded and transcribed verbatim. Data were analysed using hermeneutic interpretation within a Heideggerian phenomenological framework. Acute Coronary Syndrome disrupts lived temporality, and the projected potential for carers' being-alongside. Carers experienced an existential uncertainty that arose from difficulty in diagnosis, and situated fear as an attuned, being-towards-death. They constructed protective strategies to insulate their partner and themselves from further stress and risk, however, unclear boundaries for protection heightened carer anxiety. The existential structure of care included one of two possible Heideggerian modes: leaping-in care was a dominating mode that required a high level of carer vigilance; leaping-ahead care was a metaphorical walking alongside, as carers gave back control, freeing opportunities for the person to 'own' care. Supporting carers through the intensive phase of leaping-in care, and equipping them for informed leaping-ahead care should be a focus in both the acute and post-discharge care phases.

Learned Helplessness and Depressive Symptoms Following Myocardial Infarction

Psychosocial factors are known to impact depressive symptoms across clinical populations. Learned helplessness has the potential of affecting depressive symptoms following acute myocardial infarction (AMI), though little is known about this relationship. The purpose of this study was to examine the relationship between learned helplessness and depressive symptoms in patients following an AMI. Using a descriptive cross-sectional design, participants with a diagnosed AMI within the past 12 months were recruited. Standardized instruments and measures were used to evaluate learned helplessness and depressive symptoms. A statistically significant direct relationship was found between learned helplessness and depressive symptoms, suggesting that individuals with higher self-reported levels of learned helplessness also reported more depressive symptoms. These results indicate learned helplessness is associated with depressive symptoms in individuals following an AMI. In developing post-AMI treatment plans, health care staff should focus on psychologic points of intervention to the same extent as physiologic interventions.

Early illness experiences related to unexpected heart surgery: A qualitative descriptive study

BACKGROUND

Most studies on patients' experiences following emergency cardiac surgery focus on evaluation of patients after their discharge. Few studies have evaluated patients' experiences after being transferred from intensive care and before being discharged.

OBJECTIVE

This study aimed to describe patients' experiences in the early stages of recovery following emergency heart surgery.

METHODS

For this exploratory qualitative descriptive study, 13 patients were recruited from a medical centre in northern Taiwan. Participants had undergone emergency heart surgery and had resided in the cardiothoracic surgical ward for ≥6 days following transfer from the ICU; all expected to be discharged from the hospital within 3 days. Semi-structured, face-to-face interviews were conducted in private after the patients had been transferred to the cardiothoracic surgical wards. Audiotaped interviews were transcribed and analysed using content analysis.

FINDINGS

Data analysis identified four themes, which represented different recovery stages: sudden and serious symptoms, nightmares and vivid dreams, physical and emotional disturbances, and establishing a new life after emergency surgery. A fifth theme, support for a new lifestyle, occurred between the four stages.

CONCLUSION

Participants experienced symptoms of physical and psychological stress during the early recovery stages following emergency heart surgery. A lack of understanding of the process of recovery increased these difficulties; participants wanted and needed multidisciplinary care and education. Emergency heart surgery does not allow healthcare professionals to inform patients of what to expect post-surgery. Our findings suggest that rather than waiting until discharge to offer disease information and treatment plans, multidisciplinary care should be initiated as soon as possible to facilitate recovery.

Perspectives of older people engaging in nurse-led cardiovascular prevention programmes: a qualitative study in primary care in the Netherlands

Background

Cardiovascular prevention programmes are increasingly being offered to older people. To achieve the proposed benefits, adherence is crucial. Understanding the reasons for adherence and non-adherence can improve preventive care.

Aim

To gain insight into what motivates older people living in the community to partake in a cardiovascular prevention programme, and reasons for subsequent continuation or withdrawal.

Design and setting

Qualitative study of current and former participants of the ongoing ≥6 year PreDIVA (prevention of dementia by intensive vascular care) trial in primary care practices in suburban areas in the Netherlands.

Method

Semi-structured interviews were conducted with a purposive sample of 15 participants (aged 76–82 years). Interviews were audiorecorded and analysed by two independent researchers using a thematic approach. Participants were asked about their motivation for participating in the programme, along with the facilitators and barriers to continue doing so.

Results

Responders reported that regular check-ups offered a feeling of safety, control, or being looked after, and were an important motivator for participation. For successful continuation, a personal relationship with the nurse and a coaching approach were both essential; the lack of these, along with frequent changes of nursing staff, were considered to be barriers. Participants considered general preventive advice unnecessary or patronising, but practical support was appreciated.

Conclusion

To successfully engage older people in long-term, preventive consultations, the approach of the healthcare provider is crucial. Key elements are to offer regular check-ups, use a coaching approach and to build a personal relationship with the patient.

Mussel‐Inspired Conductive Cryogel as Cardiac Tissue Patch to Repair Myocardial Infarction by Migration of Conductive Nanoparticles

The engineered cardiac patch (ECP) is a promising strategy to repair infarct myocardium and restore the cardiac function. An ideal ECP should be able to mimic the primary attributes of native myocardium, which includes a high resilience, good cardiomyocyte adhesion, and synchronous contraction. Here, a mussel‐inspired dopamine crosslinker is used to integrate polypyrrole (Ppy) nanoparticles, gelatin‐methyacrylate, and poly(ethylene glycol) diacrylate into a cryogel form. The dopamine crosslinker and Ppy nanoparticles are coordinated to obtain optimal mechanical and superelastic properties for the ECP. The dopamine facilitates the uniform distribution of the Ppy nanoparticles, which migrate and fuse from the scaffold to the surface of the cardiomyocytes, revealing a potential mechanism for restoring infarct myocardium. The incorporated Ppy nanoparticles thus significantly enhance the functionalization of the cardiomyocytes, resulting in excellent synchronous contraction by increasing the expression of α‐actinin and CX‐43. Cardiomyocytes‐loaded ECP can improve the cardiac function in myocardial‐infarction (MI) affected rat models. The results show that the fractional shortening and ejection fraction are elevated by about 50% and that the infarct size is reduced by 42.6%. Collectively, this study highlights an effective cardiac patch based on mussel‐inspired conductive particle adhesion and a superelastic cryogel promising for the restoration of infarcted myocardium.

The effectiveness and experience of self-management following acute coronary syndrome: A review of the literature

OBJECTIVES

To evaluate the effectiveness of interventions used to support self-management, and to explore patients' experiences after acute coronary syndrome in relation to self-management.

DESIGN

Scoping review.

DATA SOURCES

Keyword search of CINAHL Plus, Medline, the Cochrane Library, and PsycINFO databases for studies conducted with adult population and published in English between 1993 and 2014.

REVIEW METHODS

From title and abstract review, duplicated articles and obviously irrelevant studies were removed. The full texts of the remaining articles were assessed against the selection criteria. Studies were included if they were original research on: (1) effectiveness of self-management interventions among individuals following acute coronary syndrome; or (2) patients' experience of self-managing recovery from acute coronary syndrome.

RESULTS

44 articles (19 quantitative and 25 qualitative) were included. Most studies were conducted in western countries and quantitative studies were UK centric. Self-management interventions tended to be complex and include several components, including education and counselling, goal setting and problem solving skills which were mainly professional-led rather than patient-led. The review demonstrated variation in the effectiveness of self-management interventions in main outcomes assessed - anxiety and depression, quality of life and health behavioural outcomes. For most participants in the qualitative studies, acute coronary syndrome was unexpected and the recovery trajectory was a complex process. Experiences of making adjustment and adopting lifestyle changes following acute coronary syndrome were influenced by subjective life experiences and individual, sociocultural and environmental contexts. Participants' misunderstandings, misconceptions and confusion about disease processes and management were another influential factor. They emphasised a need for ongoing input and continued support from health professionals in their self-management of rehabilitation and recovery, particularly during the initial recovery period following hospital discharge.

CONCLUSIONS

Evidence of the effectiveness of self-management interventions among people with acute coronary syndrome remains inconclusive. Findings from the patients' experiences in relation to self-management following acute coronary syndrome provided important insights into what problems patients might have encountered during self-managing recovery and what support they might need, which can be used to inform the development of self-management interventions. Theoretical or conceptual frameworks have been minimally employed in these studies and should be incorporated in future development and evaluation of self-management interventions as a way of ensuring clarity and consistency related to how interventions are conceptualised, operationalised and empirically studied. Further research is needed to evaluate self-management interventions among people following acute coronary syndrome for sustained effect and within different health care contexts.

Perspectives on barriers and facilitators to self-care in Lebanese cardiac patients: A qualitative descriptive study

BACKGROUND

Cardiovascular disease is the leading cause of mortality worldwide. Cardiac self-care practices are essential for managing cardiac illness and improving quality of life. However, these practices may be affected by factors that may hinder or facilitate self-care especially in countries that experience political and economic instabilities.

OBJECTIVES

The purpose of this study was to explore self-care practices among Lebanese cardiac patients. Another aim was to reveal factors that might influence these self-care practices.

DESIGN

This is a qualitative descriptive study.

SETTING

Participants were recruited from a referral medical center in Beirut, Lebanon and interviews took place in their homes.

PARTICIPANTS

Purposive sample of 15 adult participants, seven females and eight males, diagnosed with coronary artery disease at least a year ago and not in critical condition recruited from the cardiology clinics of the medical center.

METHODS

Data were collected through semi-structured audio-recorded interviews that took place in their places of residents.

RESULTS

Three themes emerged from the data: I. The behaviors of cardiac patients demonstrated selected self-care practices; II. Patients identified barriers to self-care reflective of the Lebanese political and socio-economic situation; and, III. Patients described facilitators to self-care consistent with the Lebanese socio-cultural values and norms. The most common self-care practices included taking medications and eating properly. Participants emphasized avoiding stress and being upset as a self-protective measure for cardiac health. Health care costs, family responsibilities, psychological factors and the country's political situation impeded self-care practices whereas family support facilitated them.

CONCLUSION

Lebanese patients reported select self-care practices in dealing with their cardiac illness. Barriers and facilitators to their self-care behaviors reflected the Lebanese context and culture. Thus health care providers must assess their patients' practices within their sociocultural context so that interventions to promote self-care are tailored accordingly.

Depressive symptoms in patients with acute coronary syndrome

OBJECTIVE

To trace an epidemiological profile, to verify presence of depressive symptoms in patients with previous diagnosis of acute coronary syndrome and to identify factors that contribute to maintenance of depressive symptoms in the sample.

METHODS

A cross-section study carried out at the Cardiology Outpatients Clinics of Universidade Federal de São Paulo. An instrument prepared by the authors was used, which was based on similar studies with patient identification data, questions related to the psychological follow-up, relationship with family members and friends, in addition to use of the Beck Depression Inventory.

METHODS

A cross-section study carried out at the Cardiology Outpatients Clinics of Universidade Federal de São Paulo. An instrument prepared by the authors was used, which was based on similar studies with patient identification data, questions related to the psychological follow-up, relationship with family members and friends, in addition to use of the Beck Depression Inventory.

RESULTS

A total of 200 patients were interviewed, 127 (63.5%) were male. The mean age was 60.19 years with a standard deviation of 9.38, minimum age of 36 years and maximum of 81 years; 164 (82%) denied any follow-up with a psychologist or psychiatrist in the phase after acute coronary syndrome diagnosis and treatment. In the utilization of Beck Depression Inventory, 67 (33.5%) presented scores between 0 and 4, indicating mild depressive symptoms; 72 (36%) had scores between 5 and 9, indicating mild to moderate depressive symptoms, and 61 (30.5%) presented scores greater than 9, which point out moderate to severe depressive symptoms.

CONCLUSION

The evaluation and multiprofessional follow-up can help patients cope with the illness in addition to providing greater compliance to drug therapy and beginning changes in life habits.

Clustering of lifestyle characteristics and their association with cardio-metabolic health: the Lifestyles and Endothelial Dysfunction (EVIDENT) study

Little is known about the clustering patterns of lifestyle behaviours in adult populations. We explored clusters in multiple lifestyle behaviours including physical activity (PA), smoking, alcohol use and eating habits in a sample of adult population. A cross-sectional and multi-centre study was performed with six participating groups distributed throughout Spain. Participants (n 1327) were part of the Lifestyles and Endothelial Dysfunction (EVIDENT) study and were aged between 20 and 80 years. The lifestyle and cardiovascular risk (CVR) factors were analysed using a clustering method based on the HJ-biplot coordinates to understand the variables underlying these groupings. The following three clusters were identified. Cluster 1: unhealthy, 677 subjects (51 %), with a slight majority of men (58·7 %), who were more sedentary and smokers with higher consumption of whole-fat dairy products, bigger waist circumference as well as higher TAG levels, systolic blood pressure (SBP) and CVR. Cluster 2: healthy/PA, 265 subjects (20 %), including 24·0 % of males with high PA. Cluster 3: healthy/diet, including 29 % of the participants, with a higher consumption of olive oil, fish, fruits, nuts, vegetables and lower alcohol consumption. Using the unhealthy cluster as a reference, and after adjusting for age and sex, the multiple regression analysis showed that belonging to the healthy/PA cluster was associated with a lower waist circumference, body fat percentage, SBP and CVR. In summary, the three clusters were identified according to lifestyles. The ‘unhealthy’ cluster had the least favourable clinical parameters, the ‘healthy/PA’ cluster had good HDL-cholesterol levels and low SBP and the ‘healthy/diet’ cluster had lower LDL-cholesterol levels and clinical blood pressure.

Role of the Lebanese family caregivers in cardiac self-care: a collective approach

AIMS AND OBJECTIVES

The purpose of this study was to explore perceptions of cardiac self-care among Lebanese family caregivers of cardiac patients. The specific aims were to describe the cultural context of cardiac care-giving in Lebanon and to explore the roles of family caregivers in enhancing self-care practices in patients with cardiac diseases.

BACKGROUND

The role of family caregivers in Lebanon, a country in the Middle East, is assumed to extend beyond care-giving to making decisions on behalf of the patient and assuming responsibility for patient care. To date, there has been no study done to empirically validate this impression.

DESIGN

The design of the study is qualitative descriptive that used semi-structured individual interviews with family caregivers of Lebanese cardiac patients.

METHOD

Thirteen family caregivers of cardiac patients were recruited from a referral medical centre in Lebanon. The participants were designated by their patients and interviewed in a place of their choice.

RESULTS

One overarching and three themes emerged from data analysis describing roles of family care givers in cardiac self-care. The overarching theme was: Family caregivers of Lebanese cardiac patients were unfamiliar with the term, concept and meaning of Self-Care. The moral and emotional duty to care for the family member stemmed from obligation and responsibility towards patients (theme I). Interdependent care (theme II) between cardiac patients and their families emerged as a significant cultural role. Family members play multiple supportive roles in care-giving namely emotional, informational and instrumental role (theme III).

CONCLUSION

In this study, family caregiver role is shown to be based in the sense of obligation and duty towards the sick family member who collectively provide different types of supportive care.

RELEVANCE TO CLINICAL PRACTICE

Nurses have to give significant importance to the family caregiver role as an integral part of any culturally sensitive patient/family intervention.

The Cultural Meaning of Cardiac Illness and Self-Care Among Lebanese Patients With Coronary Artery Disease

BACKGROUND

Cardiac disease is the leading cause of death in Lebanon, accounting for 22% to 26% of total deaths in the country. A thorough understanding of perceptions of cardiac illness and related self-care management is critical to the development of secondary prevention programs that are specific to the Lebanese culture.

PURPOSE

To explore the cultural perceptions of cardiac illness and the associated meaning of self-care among Lebanese patients.

DESIGN

Using a qualitative descriptive method, semistructured interviews were conducted with a purposive sample of 15 Lebanese cardiac patients recruited from a medical center in Beirut, Lebanon.

FINDINGS

The qualitative descriptive analysis yielded one overarching and two other themes describing perceptions of cardiac illness and self-care within the Lebanese cultural context. The overarching cultural theme was, "Lebanese cardiac patients were unfamiliar with the term concept and meaning of self-care." Lebanese cardiac patients thanked God and accepted their fate (Theme I). The participants considered their cardiac incident a life or death warning (Theme II).

IMPLICATIONS FOR PRACTICE

Health care providers need to consider patients' cultural perception of illness while planning and evaluating cardiac self-care programs.

Anxiety and adverse health outcomes among cardiac patients: a biobehavioral model

BACKGROUND

Anxiety is a common experience among patients with acute coronary syndrome (ACS) that can have a negative impact on health outcomes. Nonetheless, the negative role of anxiety remains underappreciated, as reflected by clinicians' underrecognition and undertreatment of anxious hospitalized and nonhospitalized patients with ACS. Underappreciation of the role of anxiety is possibly related to inadequate understanding of the mechanisms whereby anxiety may adversely affect health outcomes.

PURPOSE

The aim of this study was to synthesize the evidence about potential mechanisms by which anxiety and adverse health outcomes are related.

CONCLUSIONS

A biobehavioral model links anxiety to the development of thrombogenic and arrhythmic events in patients with ACS. Biologically, anxiety may interfere with the immune system, lipid profile, automatic nervous system balance, and the coagulation cascade, whereas behaviorally, anxiety may adversely affect adoption of healthy habits and cardiac risk-reducing behaviors. The biological and behavioral pathways complement each other in the production of poor outcomes.

CLINICAL IMPLICATIONS

Anxiety requires more attention from clinical cardiology. The adverse impact of anxiety on health outcomes could be avoided by efficient assessment and treatment of anxiety.

Managing lifestyle change to reduce coronary risk: a synthesis of qualitative research on peoples' experiences

BACKGROUND

Coronary heart disease is an incurable condition. The only approach known to slow its progression is healthy lifestyle change and concordance with cardio-protective medicines. Few people fully succeed in these daily activities so potential health improvements are not fully realised. Little is known about peoples' experiences of managing lifestyle change. The aim of this study was to synthesise qualitative research to explain how participants make lifestyle change after a cardiac event and explore this within the wider illness experience.

METHODS

A qualitative synthesis was conducted drawing upon the principles of meta-ethnography. Qualitative studies were identified through a systematic search of 7 databases using explicit criteria. Key concepts were identified and translated across studies. Findings were discussed and diagrammed during a series of audiotaped meetings.

RESULTS

The final synthesis is grounded in findings from 27 studies, with over 500 participants (56% male) across 8 countries. All participants experienced a change in their self-identity from what was 'familiar' to 'unfamiliar'. The transition process involved 'finding new limits and a life worth living' , 'finding support for self' and 'finding a new normal'. Analyses of these concepts led to the generation of a third order construct, namely an ongoing process of 'reassessing past, present and future lives' as participants considered their changed identity. Participants experienced a strong urge to get back to 'normal'. Support from family and friends could enable or constrain life change and lifestyle changes. Lifestyle change was but one small part of a wider 'life' change that occurred.

CONCLUSIONS

The final synthesis presents an interpretation, not evident in the primary studies, of a person-centred model to explain how lifestyle change is situated within 'wider' life changes. The magnitude of individual responses to a changed health status varied. Participants experienced distress as their notion of self identity shifted and emotions that reflected the various stages of the grief process were evident in participants' accounts. The process of self-managing lifestyle took place through experiential learning; the level of engagement with lifestyle change reflected an individual's unique view of the balance needed to manage 'realistic change' whilst leading to a life that was perceived as 'worth living'. Findings highlight the importance of providing person centred care that aligns with both psychological and physical dimensions of recovery which are inextricably linked.

Psychosocial complications of coronary artery disease

Background:

Cardiovascular diseases are the leading causes of death around the world. The coronary artery disease (CAD) is one of the most common diseases in this category, which can be the trigger to various psychosocial complications. We believe that inadequate attention has been paid to this issue.

Objectives:

The purpose of the present study was to explore the psychosocial complications of CAD from the Iranian patients’ perspective.

Patients and Methods:

A qualitative design based on the content analysis approach was used to collect the data and analyze the perspective of 18 Iranian patients suffered from CAD, chosen by a purposeful sampling strategy. Semi-structured interviews were held in order to collect the data. Sampling was continued until the data saturation. The data were analyzed using qualitative content analysis approach by MAXQUDA 2010 software.

Results:

This study revealed the theme of the patients’ challenges with CAD. This theme consisted of: "primary challenges," including doubting early diagnosis and treatment, and feeling being different from others; "psychological issues," including preoccupation, fear of death and surgical intervention, recurrence stress , anxiety and depression; "problems of life," including financial problems, work-related problems, and family-related problems; and "sociocultural issues," including change in perspective of people towards the patient, and cultural issues.

Conclusions:

Although the management of physical problems in patients with CAD is important, psychosocial effects of this disease is more important. Thus, health care personnel should pay ample attention to identify and resolve psychosocial problems of these patients. Results of this study can be used to empower these patients.

Development and characterization of novel electrically conductive PANI-PGS composites for cardiac tissue engineering applications

Cardiovascular diseases, especially myocardial infarction, are the leading cause of morbidity and mortality in the world, also resulting in huge economic burdens on national economies. A cardiac patch strategy aims at regenerating an infarcted heart by providing healthy functional cells to the injured region via a carrier substrate, and providing mechanical support, thereby preventing deleterious ventricular remodeling. In the present work, polyaniline (PANI) was doped with camphorsulfonic acid and blended with poly(glycerol-sebacate) at ratios of 10, 20 and 30vol.% PANI content to produce electrically conductive composite cardiac patches via the solvent casting method. The composites were characterized in terms of their electrical, mechanical and physicochemical properties. The in vitro biodegradability of the composites was also evaluated. Electrical conductivity increased from 0Scm(-1) for pure PGS to 0.018Scm(-1) for 30vol.% PANI-PGS samples. Moreover, the conductivities were preserved for at least 100h post fabrication. Tensile tests revealed an improvement in the elastic modulus, tensile strength and elasticity with increasing PANI content. The degradation products caused a local drop in pH, which was higher in all composite samples compared with pure PGS, hinting at a buffering effect due to the presence of PANI. Finally, the cytocompatibility of the composites was confirmed when C2C12 cells attached and proliferated on samples with varying PANI content. Furthermore, leaching of acid dopants from the developed composites did not have any deleterious effect on the viability of C2C12 cells. Taken together, these results confirm the potential of PANI-PGS composites for use as substrates to modulate cellular behavior via electrical stimulation, and as biocompatible scaffolds for cardiac tissue engineering applications.

Patients' experiences of lifestyle discussions based on motivational interviewing: a qualitative study

Background

According to World Health Organization about 75% of cardiovascular diseases and type 2 diabetes and 40% of all cases of cancer could be prevented if the risk factors tobacco use, unhealthy diets, physical inactivity and harmful use of alcohol could be eliminated. Patients often need help in monitoring themselves to make the proper lifestyle changes and it is important that adequate support is provided to enable the patients to take control over their health. Motivational interviewing is a framework that can help to facilitate this movement. The aim of this study was to describe how patients in primary health care settings experience lifestyle discussions based on motivational interviewing.

Methods

This study has a descriptive design and qualitative content analysis was used as the method. Sixteen patients who had each visited a registered nurse for lifestyle discussions were interviewed.

Results

The results show that the lifestyle discussions could enable self-determination in the process of lifestyle change but that certain conditions were required. Mutual interaction between the patient and the nurse that contributes to a sense of well-being in the patients was a necessary condition for the lifestyle discussion to be helpful. When the discussion resulted in a new way of thinking about lifestyle and when patient initiative was encouraged, the discussion could contribute to change. The patient’s free will to make a lifestyle change and the nurse’s sensitivity in the discussions created fertile soil for change.

Conclusions

This study focuses on MI-based discussions, and the result shows that a subset of patients, who self-reported that they are motivated and aware of their role in making lifestyle changes, appreciate these strategies. However, it is not known whether discussions would be experienced in the same way if RNs used another method or if patients who were less motivated, engaged, or aware of their role in making lifestyle changes were interviewed.

Strategies for recreating normal life: Iranian coronary heart disease patients' perspectives on coping strategies

AIMS AND OBJECTIVES

To identify coping strategies used by Iranian patients with coronary heart disease.

BACKGROUND

One of the most important nursing interventions is facilitating adjustment for patients. A deeper understanding of patients' coping strategies for controlling illness and its consequences is needed.

DESIGN

A qualitative design.

METHODS

Participants were hospitalised patients diagnosed with coronary heart disease, based on documented angiographic results. A qualitative study using semi-structured interviews was conducted, and purposive sampling was performed. The qualitative content analysis determined categories and subcategories for describing and understanding coping strategies.

RESULTS

The term 'coping strategies' refers to the strategies used by participants living with coronary heart disease as they attempt to understand and control their chronic condition and return to a social and physical state as similar to their predisease condition as possible. During the data analysis, six strategies emerged: searching for meaning and information; trying to achieve comfort and control; resting more, doing less and slowing down; motivating, prioritising and caring for self; turning to religion and spirituality; and expectations and receiving assistance and support.

CONCLUSIONS

This qualitative study describes the coping strategies of Iranian patients with coronary heart disease and the commonalities with strategies for others dealing with chronic illnesses in Iran. The patients were found to use a variety of coping strategies to deal with their illness and its impacts on their lives.

RELEVANCE TO CLINICAL PRACTICE

This study contributes to the existing body of knowledge about optimal nursing care strategies for patients with coronary heart disease. Through increasing awareness of coping strategies, nurses can help their patients employ the most effective tools and reinforce constructive successful coping styles for patients who are dealing with coronary heart disease.

Coronary heart disease patients transitioning to a normal life: perspectives and stages identified through a grounded theory approach

AIMS AND OBJECTIVES

To explore how Iranian patients with coronary heart disease experience their lives.

BACKGROUND

Coronary heart disease is a leading cause of death in Iran and worldwide. Understanding qualitatively how patients experience the acute and postacute stages of this chronic condition is essential knowledge for minimising the negative consequences of coronary heart disease.

DESIGN

Qualitative study using grounded theory for the data analysis.

METHODS

Data for this study were collected through individual qualitative interviews with 24 patients with coronary heart disease, conducted between January 2009 and January 2011. Patients with angina pectoris were selected for participation through purposive sampling, and sample size was determined by data saturation. Data analysis began with initial coding and continued with focused coding. Categories were determined, and the core category was subsequently developed and finalised.

RESULTS

The main categories of the transition from acute phase to a modified or 'new normal' life were: (1) Loss of normal life. Experiencing emotions and consequences of illness; (2) Coming to terms. Using coping strategies; (3) Recreating normal life. Healthcare providers must correctly recognise the stages of transition patients navigate while coping with coronary heart disease to support and educate them appropriately throughout these stages.

CONCLUSION

Patients with coronary heart disease lose their normal lives and must work towards recreating a revised life using coping strategies that enable them to come to terms with their situations.

RELEVANCE TO CLINICAL PRACTICE

By understanding Iranian patients' experiences, healthcare providers and especially nurses can use the information to support and educate patients with coronary heart disease on how to more effectively deal with their illness and its consequences.
