Illness Beliefs in Patients with Recurrent Symptomatic Atrial Fibrillation

Depression and atrial fibrillation in a reciprocal liaison: a neuro-cardiac link

OBJECTIVE

To explore the reciprocal relationship of depression and atrial fibrillation (AF).

METHODS

A literature search was conducted in Pub Med, Scopus, and Google Scholar using relevant terms for depression and AF and respective therapies.

RESULTS

There is evidence that depression is involved in the aetiology and prognosis of AF. AF, independently of its type, incurs a risk of depression in 20-40% of patients. Also, depression significantly increases cumulative incidence of AF (from 1.92% to 4.44% at 10 years); 25% increased risk of new-onset AF is reported in patients with depression, reaching 32% in recurrent depression. Hence, emphasis is put on the importance of assessing depression in the evaluation of AF and vice versa. Persistent vs paroxysmal AF patients may suffer from more severe depression. Furthermore, depression can impact the effectiveness of AF treatments, including pharmacotherapy, anticoagulation, cardioversion and catheter ablation.

CONCLUSIONS

A reciprocal association of depression and AF, a neurocardiac link, has been suggested. Thus, strategies which can reduce depression may improve AF patients' course and treatment outcomes. Also, AF has a significant impact on risk of depression and quality of life. Hence, effective antiarrhythmic therapies may alleviate patients' depressive symptoms.

Quality of life among patients with atrial fibrillation: A theoretically-guided cross-sectional study

BACKGROUND

Patients with atrial fibrillation (AF) have significantly lower health-related quality of life (HRQoL) compared to the general population and patients with other heart diseases. The research emphasis on the influence of AF symptoms on HRQoL overshadows the role of individual characteristics. To address this gap, this study's purpose was to test an incremental predictive model for AF-related HRQoL following an adapted HRQoL conceptual model that incorporates both symptoms and individual characteristics.

METHODS

Patients attending an AF specialty clinic were invited to complete an online survey. Hierarchical regression analyses were conducted to examine whether individual characteristics (overall mental health, perceived stress, sex, age, AF knowledge, household and recreational physical activity) incremented prediction of HRQoL and AF treatment satisfaction beyond AF symptom recency and overall health.

RESULTS

Of 196 participants (mean age 65.3 years), 63% were male and 90% were Caucasian. Most reported 'excellent' or 'good' overall and mental health, had high overall AF knowledge scores, had low perceived stress scores, and had high household and recreation physical activity. The mean overall AF Effect On Quality-Of-Life Questionnaire (AFEQT) and AF treatment satisfaction scores were 70.62 and 73.84, respectively. Recency of AF symptoms and overall health accounted for 29.6% of the variance in overall HRQoL and 20.2% of the variance in AF treatment satisfaction. Individual characteristics explained an additional 13.6% of the variance in overall HRQoL and 7.6% of the variance in AF treatment satisfaction. Perceived stress and household physical activity were the largest contributors to overall HRQoL, whereas age and AF knowledge made significant contributions to AF treatment satisfaction.

CONCLUSIONS

Along with AF symptoms and overall health, individual characteristics are important predictors of HRQoL and AF treatment satisfaction in AF patients. In particular, perceived stress and household physical activity could further be targeted as potential areas to improve HRQoL.

Effects of different exercise types on quality of life for patients with atrial fibrillation: a systematic review and meta-analysis

AIM

To investigate the effectiveness of exercise and the most effective types of exercise for patients with atrial fibrillation (AF) to improve health-related quality of life (HRQoL) and exercise capacity, and reduce AF burden, AF recurrence and adverse events.

METHODS AND RESULTS

Systematic search in PubMed, Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL Plus, and SPORTDiscus for randomized controlled trials (RCTs) and nonrandomized pre-post intervention studies investigating the effect of different types of exercise on AF patients. After exclusion, 12 studies (11 RCTs, 1 prepost) with a total of 670 participants were included. Exercise interventions consisted of aerobic exercise, aerobic interval training (AIT), Qigong, yoga, and exercise-based cardiac rehabilitation (CR). There were significant positive effects of exercise on general health {mean difference [MD] = 6.42 [95% confidence interval (CI): 2.90, 9.93]; P = 0.0003; I2 = 17%} and vitality [MD = 6.18 (95% CI: 1.94, 10.41); P = 0.004; I2 = 19%)] sub-scales of the Short Form 36-item questionnaire (SF-36). Qigong resulted in a significant improvement in the 6-min walk test [MD = 105.00m (95% CI: 19.53, 190.47)]. Exercise-based CR and AIT were associated with a significant increment in V̇O2peak, and AIT significantly reduced AF burden. Adverse events were few and one intervention-related serious adverse event was reported for exercise-based CR.

CONCLUSION

Exercise led to improvements in HRQoL, exercise capacity, and reduced AF burden. The available exercise interventions for AF patients are few and heterogeneous. Future studies are needed for all types of exercise intervention in this patient group to (co-)develop an optimized exercise training intervention for AF patients.

Anxiety and Depressive Symptoms, Frailty and Quality of Life in Atrial Fibrillation

Introduction: Symptoms of atrial fibrillation (AF) can significantly affect functioning in daily life and reduce patients’ quality of life (QoL). The severity and type of AF symptoms affects not only patient’s QoL, but can be a cause of the development of emotional and psychological disorders. In addition, frailty syndrome (FS) plays important role from the point of view of developing disability and dependence on others, as well as reducing QoL. Aim: To assess the symptoms of anxiety and depression, to evaluate the co-occurrence of frailty syndrome and the impact of these factors on the quality of life of patients with AF. Methods: The study used a Polish adaptation of the Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia part III (ASTA part III), the Tilburg Frailty Indicator (TFI) and the Hospital Anxiety Depression Scale (HADS). Results: Analysis showed that anxiety symptoms and depressive symptoms correlate significantly (p < 0.05) and positively with the physical (r = 0.24; p < 0.001, r = 0.29, p = 0.002, respectively), psychological (r = 0.34, p < 0.001, r = 0.49 p < 0.001, respectively) and total quality of life (r = 0.31, p = 0.001, r = 0.414; p < 0.001, respectively) ASTA III domains. A significant (p < 0.05) positive correlation was observed between the TFI total score and the physical (r = 0.34, p < 0.001), psychological (r = 0.36, p < 0.001) and overall quality of life (r = 0.38, p < 0.001) in ASTA III domains. Conclusions: Both FS and depressive and anxiety symptoms significantly affect QoL. Understanding the relationship between anxiety and depressive symptoms, FS and QoL may allow for a more targeted approach to the treatment and care of patients with AF.

Living with Atrial Fibrillation: A Family Perspective

Aim

The aim of this study was to obtain insights from patients and their family members on how families are living with atrial fibrillation.

Background

Atrial fibrillation is the most common cardiac arrhythmia and is often described as an emerging global epidemic affecting an estimated 33.5 million people worldwide. Living with atrial fibrillation not only affects the patient but also may negatively influence family members' perceived health. The perspective of the family has previously been understudied, and more knowledge on how patients and their family members cope and adjust to life with atrial fibrillation may be helpful when developing future support for patients and their family members when coping with atrial fibrillation.

Methods

A qualitative phenomenological study with an inductive, descriptive research approach based on Giorgi's descriptive method was used. Data were gathered through 12 dyadic family interviews. The COnsolidated criteria for REporting Qualitative research checklist was followed while conducting the study.

Results

Three major themes emerged: emotional differences, changes in family life, and uncertainty about the future. Atrial fibrillation had multiple effects on the family. Frequently, several adjustments and adaptations had to be made to accommodate life with atrial fibrillation.

Conclusion

Patients with atrial fibrillation and their family members feel a need to talk about their emotions and worries. They required support and guidance to manage the challenges of living with atrial fibrillation. These results will be used in a family-focused intervention designed to support families in adjusting and managing their everyday lives with atrial fibrillation.

Fear of Recurrence of Atrial Fibrillation: Translating a Cancer Fear Model to the Atrial Fibrillation Patient Experience

BACKGROUND

Atrial fibrillation occurs when rapid and disorganized electrical signals cause the atria in the heart to beat irregularly and is associated with an increased risk for stroke. Despite medical advancements, first and second line atrial fibrillation treatments exhibit significant recurrence rates. Because of this, atrial fibrillation patients often experience disease-specific fears that are not routinely assessed and targeted in clinical management. Fear of recurrence models in cancer research and other cardiac-specific fears have paved the way for a patient-centric approach to disease intervention.

PURPOSE

Clinical assessment focused solely on the taxonomy of anxiety disorders may miss key components unique to the atrial fibrillation patient experience. An anxiety disorder diagnosis in the presence of an arrhythmia could be misleading and ultimately fail to address patient needs. Modeled from the cancer literature, providers may benefit from a broader disease specific conceptualization for AF patients that differs from a general DSM-5 diagnosis.

AIMS

The objectives of this paper are: (1) to review the medical aspects of atrial fibrillation, (2) to examine the comparability of fear of recurrence concept from cancer literature to the atrial fibrillation patient, and (3) to suggest considerations of these novel concepts in patient care.

FUTURE DIRECTIONS

Increased understanding of fear of recurrence among atrial fibrillation patients aims to define and assess fear of recurrence components, determine treatment targets, and ultimately improve patient outcomes.

Longitudinal Oral Anticoagulant Adherence Trajectories in Patients With Atrial Fibrillation

BACKGROUND

Conventional adherence summary measures do not capture the dynamic nature of adherence.

OBJECTIVES

This study aims to characterize distinct long-term oral anticoagulant adherence trajectories and the factors associated with them in patients with atrial fibrillation.

METHODS

Adults with incident atrial fibrillation were identified using linked population-based administrative health data in British Columbia, Canada (1996-2019). Group-based trajectory modeling was used to model patients' 90-day proportions of days covered over time to identify distinct 5-year adherence trajectories. Multinomial regression analysis was used to assess the effect of various demographic and clinical factors on exhibiting each adherence trajectory.

RESULTS

The study cohort included 19,749 patients with AF (mean age: 70.6 ± 10.6 years), 56% male, mean CHA₂DS₂-VASc stroke risk score 2.8 ± 1.4. Group-based trajectory modeling identified 4 distinct oral anticoagulants adherence trajectories: "consistent adherence" (n = 14,631, 74% of the cohort), "rapid decline and discontinuation" (n = 2,327, 12%), "rapid decline and partial recovery" (n = 1,973, 10%), and "slow decline and discontinuation" (n = 819, 4%). Very few patient variables were found to be associated with specific adherence trajectories.

CONCLUSIONS

There is heterogeneity among nonadherent patients in the rate and timing of decline in their medication taking. Clinical and demographic characteristics were found to be inadequate to predict patients' adherence trajectories. Insights from this study could be used to inform the design and timing of adherence interventions, and qualitative studies may be needed to better understand the psychosocial determinants and reasons for the behaviors reflected in the identified trajectories.

The Danish Future Patient Telerehabilitation Program for Patients With Atrial Fibrillation: Design and Pilot Study in Collaboration With Patients and Their Spouses

Background

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is predicted to more than double in prevalence over the next 20 years. Tailored patient education is recommended as an important aspect of AF care. Current guidelines emphasize that patients become more active participants in the management of their own disease, yet there are no rehabilitation programs for patients with AF in the Danish health care system. Through participatory design, we developed the Future Patient Telerehabilitation (TR) Programs, A and B, for patients with AF. The 2 programs are based on HeartPortal and remote monitoring, together with educational modules.

Objective

The aim of this pilot study is to evaluate and compare the feasibility of the 2 programs of TR for patients with AF.

Methods

This pilot study was conducted between December 2019 and March 2020. The pilot study consisted of testing the 2 TR programs, A and B, in two phases: (1) treatment at the AF clinic and (2) TR at home. The primary outcome of the study was the usability of technologies for self-monitoring and the context of the TR programs as seen from patients’ perspectives. Secondary outcomes were the development of patients’ knowledge of AF, development of clinical data, and understanding the expectations and experiences of patients and spouses. Data were collected through interviews, questionnaires, and clinical measurements from home monitoring devices. Statistical analyses were performed using the IBM SPSS Statistics version 26. Qualitative data were analyzed using NVivo 12.0.

Results

Through interviews, patients articulated the following themes about participating in a TR program: usefulness of the HeartPortal, feeling more secure living with AF, community of practice living with AF, and measuring heart rhythm makes good sense. Through interviews, the spouses of patients with AF expressed that they had gained increased knowledge about AF and how to support their spouses living with AF in everyday life. Results from the responses to the Jessa AF Knowledge Questionnaire support the qualitative data, as they showed that patients in program B acquired increased knowledge about AF at follow-up compared with baseline. No significant differences were found in the number of electrocardiography recordings between the 2 groups.

Conclusions

Patients with AF and their spouses were positive about the TR program and they found the TR program useful, especially because it created an increased sense of security, knowledge about mastering their symptoms, and a community of practice linking patients with AF and their spouses and health care personnel. To assess all the benefits of the Future Patient–TR Program for patients with AF, it needs to be tested in a comprehensive randomized controlled trial.

Adherence to oral anticoagulants among patients with atrial fibrillation: a systematic review and meta-analysis of observational studies

INTRODUCTION

Medications cannot exert their effect if not taken as prescribed by patients. Our objective was to summarise the observational evidence on adherence to oral anticoagulants (OACs) among patients with atrial fibrillation (AF).

METHODS

In March 2019, we systematically searched PubMed/Medline, Embase, CINAHL and PsycINFO (from inception) for observational studies measuring adherence, its determinants and impacts in patients with AF. Mean adherence measures and corresponding proportions of adherent patients were pooled using random effects models. Factors shown to be independently associated with adherence were extracted as well as the clinical and economic outcomes of adherence.

RESULTS

We included 30 studies. Pooled mean adherence scores of over half a million patients with AF 6 months and 1 year after therapy initiation were 77 (95% CI: 74-79) and 74 (68-79) out of 100, respectively. Drug-specific pooled mean adherence score at 6 months and 1 year were as follows: rivaroxaban: 78 (73-84) and 77 (69-86); apixaban: 77 (75-79) and 82 (74-89); dabigatran: 74 (69-79) and 75 (68-82), respectively. There was inadequate information on warfarin for inclusion in meta-analysis.Factors associated with increased adherence included: older age, higher stroke risk, once-daily regimen, history of hypertension, diabetes or stroke, concomitant cardiovascular medications, living in rural areas and being an experienced OAC user. Non-adherent patients were more likely to experience stroke and death, and incurred higher medical costs compared with patients with poor adherence.

CONCLUSIONS

Our findings show that up to 30% of patients with AF are non-adherent, suggesting an important therapeutic challenge in this patient population.

MediYoga as a part of a self-management programme among patients with paroxysmal atrial fibrillation - a randomised study

BACKGROUND

Paroxysmal atrial fibrillation is associated with impaired health-related quality of life. Yoga has been suggested to improve health-related quality of life among patients with heart failure and hypertension.

AIM

The aim of the study was to evaluate the effects of MediYoga, in respect of health-related quality of life, blood pressure, heart rate, as well as N-terminal pro b-type natriuretic peptide, among patients with symptomatic paroxysmal atrial fibrillation, compared with standard therapy or relaxation.

METHODS

Patients with symptomatic paroxysmal atrial fibrillation, n=132, were stratified for gender and randomised to MediYoga, a relaxation group or a control group, 44 patients per group with a 12-week follow-up. Health-related quality of life, blood pressure, heart rate and N-terminal pro b-type natriuretic peptide were assessed.

RESULTS

After 12 weeks, there were no differences in health-related quality of life between the groups. There were improvements in Short-Form Health Survey bodily pain, general health, social function, mental health and mental component summary scores within the MediYoga group (p=0.014, p=0.037, p=0.029, p=0.030, p=0.019, respectively). No change was seen in the relaxation and control groups. Systolic blood pressure decreased in the MediYoga group (134±18 to 127±13) compared with the control group (126±17 to 127±15, p=0.041); no difference compared with the relaxation group (131±17 to 125±12). Diastolic blood pressure decreased in the MediYoga group (79±9 to 74 ±9) compared with the control group (76±9 to 79±8, p=0.005); no difference compared with the relaxation group (76±9 to 77±8). There were no differences in heart rate and N-terminal pro b-type natriuretic peptide between the groups after 12 weeks.

CONCLUSIONS

MediYoga improves health-related quality of life and decreases blood pressure in patients with paroxysmal atrial fibrillation. MediYoga may be used as a part of a self-management programme among patients with paroxysmal atrial fibrillation.

Assessment of Condition and Medication Knowledge Gaps Among Atrial Fibrillation Patients: A Systematic Review and Meta-analysis

Background: Patient education facilitates construction of a correct illness representation, improves beliefs about medications, and improves knowledge, factors that have been associated with better adherence. Objective: Our objective was to characterize the published literature about atrial fibrillation (AF) patients’ disease and medication knowledge to identify knowledge gaps and misconceptions to inform AF patient education strategies. Methods: Following PRISMA guidelines, we searched PubMed, EMBASE, CINAHL, and PsychINFO from inception to May 2018 for studies that assessed AF patients’ knowledge about their condition and medications. For quantitative studies, we extracted the proportion of participants who provided correct answers to the questions asked about their condition, medications, or risk of stroke. We classified data for related questions into knowledge domains. A random-effects meta-analysis was conducted for each knowledge domain. A domain was considered a knowledge gap if the pooled mean proportion of participants who demonstrated knowledge of it was ≤50%, regardless of CI. Qualitative data were summarized narratively. Results: A total of 21 studies were included. AF- and stroke-related knowledge gaps and misconceptions included the following: AF can be asymptomatic, AF can predispose to heart failure, women are at a higher risk of stroke, the definition of ischemic stroke, and patients’ awareness of their diagnosis. Medication-related knowledge gaps were antithrombotic-drug interactions, antithrombotic-food interactions, vitamin K content of foods, the term INR (international normalized ratio) and its interpretation, and the required actions in case of a missed dose. Conclusion and Relevance: This systematic review identified several AF patient knowledge gaps about their condition and its treatment that can inform the development of AF patient education programs.

Perceptions and experiences of MediYoga among patients with paroxysmal atrial fibrillation-An interview study

OBJECTIVES

We investigated the perceptions and experiences of a therapeutic yoga form, MediYoga, which is evolved from Kundaliniyoga among patients with symptomatic paroxysmal atrial fibrillation (PAF).

DESIGN AND SETTING

an inductive exploratory design was chosen with individual semi-structured interviews. The study was conducted with 12 participants (7 men and 5 women, average age 63.5) at a university hospital, Sweden. Informed consent was obtained from all participants. The data were analyzed using a qualitative content analysis with an inductive method and a manifest approach.

RESULTS

Three categories were found in the analysis. In the category "A time for a sense of existence and presence", the patients described an increased thoughtfulness and experiences of gaining access to an inner self. The category "A way of gaining well-being and increased consciousness" describes patients` feelings of relaxation and feeling of comfort, with components of mental and physical well-being. Furthermore, "Access to a tool to gain willpower and relieve symptoms" describes the perceptions from patients to obtained access to a tool for handling the emotions, such as fear and anxiety, as well as symptoms that they could struggling with between, and during, their episodes of atrial fibrillation. No adverse events were reported by the yoga group, during the study.

CONCLUSIONS

Patients with PAF described MediYoga as an accessible tool to manage emotions and symptoms related to episodes of AF. MediYoga may also assist in enhancing body awareness, whereby physical, mental and spiritual components are integrated. MediYoga may strengthen self-management among patients with PAF.

An Autonomic Network: Synchrony Between Slow Rhythms of Pulse and Brain Resting State Is Associated with Personality and Emotions

The sympathetic system's role in modulating vasculature and its influence on emotions and personality led us to test the hypothesis that interactions between brain resting-state networks (RSNs) and pulse amplitude (indexing sympathetic activity) would be associated with emotions and personality. In 203 participants, we characterized RSN spatiotemporal characteristics, and phase-amplitude associations of RSN fluctuations with pulse and respiratory recordings. We found that RSNs are spatially reproducible within participants and were temporally associated with low frequencies (LFs < 0.1 Hz) in physiological signals. LF fluctuations in pulse amplitude were not related to cardiac electrical activity and preceded LF fluctuations in RSNs, while LF respiratory amplitude fluctuations followed LF fluctuations in RSNs. LF phase dispersion (PD) (lack of synchrony) between RSNs and pulse (PDpulse) (not respiratory) correlated with the common variability in measures of personality and emotions, with more synchrony being associated with more positive temperamental characteristics. Voxel-level PDpulse mapping revealed an "autonomic brain network," including sensory cortices and dorsal attention stream, with significant interactions with peripheral signals. Here, we uncover associations between pulse signal amplitude (presumably of sympathetic origin) and brain resting state, suggesting that interactions between central and autonomic nervous systems are important for characterizing personality and emotions.

Atrial Fibrillation Burden: Moving Beyond Atrial Fibrillation as a Binary Entity: A Scientific Statement From the American Heart Association

Our understanding of the risk factors and complications of atrial fibrillation (AF) is based mostly on studies that have evaluated AF in a binary fashion (present or absent) and have not investigated AF burden. This scientific statement discusses the published literature and knowledge gaps related to methods of defining and measuring AF burden, the relationship of AF burden to cardiovascular and neurological outcomes, and the effect of lifestyle and risk factor modification on AF burden. Many studies examine outcomes by AF burden classified by AF type (paroxysmal versus nonparoxysmal); however, quantitatively, AF burden can be defined by longest duration, number of AF episodes during a monitoring period, and the proportion of time an individual is in AF during a monitoring period (expressed as a percentage). Current guidelines make identical recommendations for anticoagulation regardless of AF pattern or burden; however, a review of recent evidence suggests that higher AF burden is associated with higher risk of stroke. It is unclear whether the risk increases continuously or whether a threshold exists; if a threshold exists, it has not been defined. Higher burden of AF is also associated with higher prevalence and incidence of heart failure and higher risk of mortality, but not necessarily lower quality of life. A structured and comprehensive risk factor management program targeting risk factors, weight loss, and maintenance of a healthy weight appears to be effective in reducing AF burden. Despite this growing understanding of AF burden, research is needed into validation of definitions and measures of AF burden, determination of the threshold of AF burden that results in an increased risk of stroke that warrants anticoagulation, and discovery of the mechanisms underlying the weak temporal correlations of AF and stroke. Moreover, developments in monitoring technologies will likely change the landscape of long-term AF monitoring and could allow better definition of the significance of changes in AF burden over time.

Planning Telehealth for Older Adults With Atrial Fibrillation in Rural Communities: Understanding Stakeholder Perspectives

Older adults with atrial fibrillation (AF) in rural communities have less access to cardiac specialty care. Telehealth offers a viable approach to provide cardiac care, yet little is known about patients’ and providers’ views on telehealth’s potential to support rural patients with AF. This qualitative descriptive study examines patient and health providers’ perspectives, an important first step in planning a telehealth initiative. Eight patients with AF, along with one partner from rural communities, were recruited through an urban-based AF clinic. Five providers were recruited through professional practice leads in the health region. Semistructured telephone interviews were conducted with both stakeholder groups. The overriding theme was variability in patient and provider receptiveness to telehealth. Receptiveness reflected differences in past experience with telehealth, in perceived adequacy of rural health services, and in perceived gaps in AF care. These are important considerations in planning effective and sustainable telehealth in rural communities.

The heart is a representation of life: an exploration of illness beliefs in couples living with atrial fibrillation

AIMS AND OBJECTIVES

To explore illness beliefs in couples where one spouse has atrial fibrillation.

BACKGROUND

Beliefs are the lenses through which we view the world, guiding our behaviour and constructing our lives. Couples evolve an ecology of beliefs from their interaction whereby their actions and choices arise from their beliefs. Atrial fibrillation is a common cardiac arrhythmia that has implications for both patients and partners. A couple's illness beliefs play an important role in convalescence and illness management, and no previous studies have explored illness beliefs in couples living with atrial fibrillation.

DESIGN

A qualitative hermeneutic design.

METHODS

Data collection constituted in-depth interviews with nine couples (patient and partner together). Hermeneutic philosophy as described by Gadamer was used to interpret and to understand illness beliefs in couples living with atrial fibrillation.

RESULTS

The findings revealed both core illness beliefs and secondary illness beliefs. From the core illness belief 'The heart is a representation of life', two secondary illness beliefs were derived: atrial fibrillation is a threat to life and atrial fibrillation can and must be explained. From the core illness belief 'Change is an integral part of life', two secondary illness beliefs were derived: atrial fibrillation is a disruption in our lives and atrial fibrillation will not interfere with our lives. Finally, from the core illness belief 'Adaptation is fundamental in life', two secondary illness beliefs were derived: atrial fibrillation entails adjustment in daily life and atrial fibrillation entails confidence in and adherence to professional care.

CONCLUSION

Couples' interaction has developed mutual illness beliefs regarding atrial fibrillation that guide them in their daily lives and influence their decisions. The adoption of a family-centred perspective in cardiovascular care settings is warranted.

Reproducibility and Reliability of the Quality of Life Questionnaire in Patients With Atrial Fibrillation

BACKGROUND

Studies have shown the impact of atrial fibrillation (AF) on the patients' quality of life. Specific questionnaires enable the evaluation of relevant events. We previously developed a questionnaire to assess the quality of life of patients with AF (AFQLQ version 1), which was reviewed in this study, and new domains were added.

OBJECTIVE

To demonstrate the reproducibility of the AFQLQ version 2 (AFQLQ v.2), which included the domains of fatigue, illness perception and well-being.

METHODS

We applied 160 questionnaires (AFQLQ v.2 and SF-36) to 40 patients, at baseline and 15 days after, to measure inter- and intraobserver reproducibility. The analysis of quality of life stability was determined by test-retest, applying the Bartko intraclass correlation coefficient (ICC). Internal consistency was assessed by Cronbach's alpha test.

RESULTS

The total score of the test-retest (n = 40) had an ICC of 0.98 in the AFQLQ v.2, and of 0.94 in the SF36. In assessing the intra- and interobserver reproducibility of the AFQLQ v.2, the ICC reliability was 0.98 and 0.97, respectively. The internal consistency had a Cronbach's alpha coefficient of 0.82, compatible with good agreement of the AFQLQ v.2.

CONCLUSION

The AFQLQ v.2 performed better than its previous version. Similarly, the domains added contributed to make it more comprehensive and robust to assess the quality of life of patients with AF.

Associations of Emotional Distress and Perceived Health in Persons With Atrial Fibrillation and Their Partners Using the Actor-Partner Interdependence Model

Individual behavior affects and is affected by other people. The aim of this study was to examine if emotional distress in patients with atrial fibrillation (AF) and their spouses was associated with their own and their partner's perceived health. Participants included 91 dyads of patients and their spouses. Emotional distress was measured using the Hospital Anxiety and Depression Scale and perceived health was measured with the Short Form 36 Health Survey. The Actor-Partner Interdependence Model was used for dyad-level analyses of associations, using structural equation modeling. Higher levels of anxiety and depression were associated with lower levels of perceived health in patients and spouses. Higher levels of depression in patients were associated with lower levels of vitality in spouses and vice versa. As AF patients and their spouses influence each other, health-care interventions should consider the dyad to address dyadic dynamics. This may benefit the health of the individual patient and of the couple.

Symptoms In Atrial Fibrillation: A Contemporary Review And Future Directions

Atrial fibrillation (AF) is the most prevalent arrhythmia leading to hospital admissions in the United States. The majority of patients with AF report symptoms associated with this condition that can lead to a decrease in health related quality of life (HRQOL) and functional status. Therefore, along with reducing the risk of stroke and mortality, improvements in such symptoms are important therapeutic goals in the management of patients with AF. Our current understanding of how AF and symptoms are linked is hampered by the dominant assessment paradigm, where symptoms thought to be associated with AF are measured at a single point in time (frequently at a clinic visit). Unfortunately, this "static" snapshot does not capture the variability of symptoms and heart rhythm within a person over time and does not shed light on how symptoms are related to heart rhythm. This focused review summarizes current methods for assessing symptoms including generic and AF-specific HRQOL and functional status tools. It also describes gaps in the current assessment paradigm and where future research using mobile applications and digital technology might be able to assist with patient care.

Developing a Complex Educational-Behavioural Intervention: The TREAT Intervention for Patients with Atrial Fibrillation

This article describes the theoretical and pragmatic development of a patient-centred intervention for patients with atrial fibrillation (AF). Theoretical models (Common Sense Model, Necessity-Concerns Framework), clinical frameworks, and AF patient feedback contributed to the design of a one-off hour-long behaviour-change intervention package. Intervention materials consisted of a DVD, educational booklet, diary and worksheet, which were patient-centred and easy to administer. The intervention was evaluated within a randomised controlled trial. Several “active theoretical ingredients” were identified (for e.g., where patients believed their medication was less harmful they spent more time within the therapeutic range (TTR), with general harm scores predicting TTR at 6 months). Allowing for social comparison and adopting behaviour change techniques enabled accurate patient understanding of their condition and medication. The process of developing the intervention using theory-derived content and evaluation tools allowed a greater understanding of the mechanisms by which this intervention was successful. Alleviating concerns about treatment medication by educating patients can help to improve adherence. This process of intervention development could be adopted for a range of chronic illnesses and treatments. Critical elements should include the use of: (1) clinical guidelines; (2) appropriate theoretical models; (3) patient input; and (4) appropriate evaluation tools.

The Stressors and Coping Strategies of Older Adults With Persistent Atrial Fibrillation Prior to and Following Direct Current Cardioversion

Objective:The purpose of this study was to explore the stressors and coping strategies of older adults with persistent atrial fibrillation (AF) before and after direct current cardioversion. Method: The study used a qualitative descriptive design. Sixteen patients were recruited through an AF clinic to participate in individual interviews prior to the cardioversion and at 6 and 12 weeks post procedure. Results: Pre-cardioversion, older adults experienced symptom and health care–related stressors superimposed on existing non-AF stressors. They used a range of emotion and problem-focused coping. Non-AF stressors increased post procedure at the same time that participants perceived less need for coping strategies with a return to regular rhythm. Discussion: There was a shift from AF to non-AF related stressors following the cardioversion but a decrease in coping strategies. Older adults with AF should be encouraged to maintain use of coping strategies to manage ongoing stress and reduce the risk of AF recurrence.

The well-being of relatives of patients with atrial fibrillation: a critical incident technique analysis

Background:

The well-being of relatives of patients having chronic heart diseases (CHD) has been found to be negatively affected by the patient’s condition. Studies examining relatives of patients with atrial fibrillation (AF) indicate that their well-being may be affected in a similar manner, but further research is needed.

Aim:

To explore and describe critical incidents in which relatives of patients experience how AF affects their well-being and what actions they take to handle these situations. Design and method: An explorative, descriptive design based on the critical incident technique (CIT) was used. Interviews were conducted with 19 relatives (14 women and five men) of patients hospitalised in southern Sweden due to acute symptoms of the AF.

Results:

The well-being of relatives was found to be affected by their worries (patient-related health), as well as the sacri-ficing of their own needs (self-related health). In handling their own well-being, these relatives adjusted to and supported the patient (practical involvement), along with adjusting their own feelings and responding to the mood of the patients (emotional involvement).

Conclusion:

The well-being of relatives of patients with AF was affected depending on the patients’ well-being. In their attempt to handle their own well-being, the relatives adjusted to and supported the patients. Further research is needed in order to evaluate the effects of support to relatives and patients respectively and together.

Educational intervention improves anticoagulation control in atrial fibrillation patients: the TREAT randomised trial

BACKGROUND

Stroke prevention in atrial fibrillation (AF), most commonly with warfarin, requires maintenance of a narrow therapeutic target (INR 2.0 to 3.0) and is often poorly controlled in practice. Poor patient-understanding surrounding AF and its treatment may contribute to the patient's willingness to adhere to recommendations.

METHOD

A theory-driven intervention, developed using patient interviews and focus groups, consisting of a one-off group session (1-6 patients) utilising an "expert-patient" focussed DVD, educational booklet, self-monitoring diary and worksheet, was compared in a randomised controlled trial (ISRCTN93952605) against usual care, with patient postal follow-ups at 1, 2, 6, and 12-months. Ninety-seven warfarin-naïve AF patients were randomised to intervention (n=46, mean age (SD) 72.0 (8.2), 67.4% men), or usual care (n=51, mean age (SD) 73.7 (8.1), 62.7% men), stratified by age, sex, and recruitment centre. Primary endpoint was time within therapeutic range (TTR); secondary endpoints included knowledge, quality of life, anxiety/depression, beliefs about medication, and illness perceptions.

MAIN FINDINGS

Intervention patients had significantly higher TTR than usual care at 6-months (76.2% vs. 71.3%; p=0.035); at 12-months these differences were not significant (76.0% vs. 70.0%; p=0.44). Knowledge increased significantly across time (F (3, 47) = 6.4; p<0.01), but there were no differences between groups (F (1, 47) = 3.3; p = 0.07). At 6-months, knowledge scores predicted TTR (r=0.245; p=0.04). Patients' scores on subscales representing their perception of the general harm and overuse of medication, as well as the perceived necessity of their AF specific medications predicted TTR at 6- and 12-months.

CONCLUSIONS

A theory-driven educational intervention significantly improves TTR in AF patients initiating warfarin during the first 6-months. Adverse clinical outcomes may potentially be reduced by improving patients' understanding of the necessity of warfarin and reducing their perception of treatment harm. Improving education provision for AF patients is essential to ensure efficacious and safe treatment. The trial is registered with Current Controlled Trials, ISRCTN93952605, and details are available at www.controlled-trials.com/ISRCTN93952605.

A systematic review of depression and anxiety in patients with atrial fibrillation: the mind-heart link

Atrial fibrillation (AF) is the most commonly seen arrhythmia in clinical practice. At present, few studies have been conducted centering on depression and anxiety in AF patients. Our aim in this systematic review is to use the relevant literature to (1) describe the prevalence of depression and anxiety in AF patients, (2) assess the impact that depression and anxiety have on illness perception in patients with AF, (3) provide evidence to support a hypothetical connection between the pathophysiology of AF and depression and anxiety, (4) evaluate the benefit of treatment of AF on depression and anxiety, and (5) give insight on medically managing a patient with AF and concomitant depression and anxiety.

Patients' well-being: experience and actions in their preventing and handling of atrial fibrillation

BACKGROUND

Atrial fibrillation (AF) influences the lives of patients in the form of worsened well-being. Patients' own experience of and how to handle AF is rarely investigated. These are important aspects for healthcare services to understand in order to support the well-being of patients with AF.

AIM

To explore and describe critical incidents in which patients experience how AF affects their well-being and what actions they take to prevent and handle it.

DESIGN AND METHODS

An explorative, descriptive design based on the critical incident technique (CIT) was used. Interviews were conducted with 25 patients (16 men and 9 women) with AF in a healthcare area in southern Sweden.

RESULTS

Patients experienced discomfort and limitations in daily life. The actions they took were self-care related actions and healthcare related actions.

CONCLUSION

AF affects well-being when it is uncomfortable and leads to pronounced limitations in daily life with the patients trying to maintain or restore well-being through adapting and developing strategies for self-care. Patients base the handling of AF on their personal experience.

What patients want and need to know about atrial fibrillation

Clinicians in a variety of settings are called upon to care for patients diagnosed with atrial fibrillation (AF), a common chronic condition that affects up to 3 million people in the USA. Evidence-based guidelines provide clinicians with direction for treatment of AF, but recommended content for educating patients and counseling about self-management of AF is not included in published guidelines. When patients believe they have a good understanding of AF they report fewer symptoms, perceive greater control over AF, and attribute less emotional distress to AF. Thus, providing patients with information about AF and how to manage it is important for promoting positive outcomes. The purpose of this article is to offer evidence-based recommendations for content to include in self-management education and counseling for patients with AF. Approaches for educating and counseling patients related to AF pathophysiology, the nature of AF (its cause, consequences, and trajectory), treatments, action plans, and symptom management, and managing the psychosocial challenges of living with AF, are discussed.
