The widespread use of cardiac implantable electronic devices and wearable monitors has led to the detection of subclinical atrial fibrillation in a substantial proportion of patients. There is ...evidence that these asymptomatic arrhythmias are associated with increased risk of stroke. Thus, detection of subclinical atrial fibrillation may offer an opportunity to reduce stroke risk by initiating anticoagulation. However, it is unknown whether long-term anticoagulation is warranted and in what populations. This scientific statement explores the existing data on the prevalence, clinical significance, and management of subclinical atrial fibrillation and identifies current gaps in knowledge and areas of controversy and consensus.
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.
The prognostic significance of the clinical presentation of atrial fibrillation (AF) is poorly defined.
The purpose of this study was to determine the frequency, associations, and prognostic impact ...of different clinical presentations of new-onset AF.
One thousand patients with incident AF in Olmsted County, Minnesota, were randomly selected (2000-2010). Patients with AF that was complicated at presentation (heart failure n = 71, thromboembolism n = 24), provoked (n = 346), or unable to determine symptoms (n = 83) were excluded. In the remaining patients, characteristics and prognosis associated with different types of symptoms were examined.
Among 476 patients, 193 had typical (palpitations), 122 had atypical (other non-palpitation symptoms), and 161 had asymptomatic AF presentation. Patients with typical presentation had lower CHA2DS2-VASc scores (mean 2.3 ± 2) compared to atypical and asymptomatic presentation (mean 3.2 ± 1.8 and 3.3 ± 1.9, respectively; P <.001). Fifty-nine cerebrovascular events and 149 deaths (n = 49 cardiovascular) were documented over median 5.6 and 6.0 years, respectively. Atypical and asymptomatic AF conferred higher risks of cerebrovascular events compared to typical AF after adjustment for CHA2DS2-VASc score and age (hazard ratio HR 3.51, 95% confidence interval CI 1.65-7.48, and HR 2.70, 95% CI 1.29-5.66, respectively), and associations remained statistically significant after further adjustments including comorbidities and warfarin use. Asymptomatic AF was associated with an increased risk of cardiovascular (HR 3.12, 95% CI 1.50-6.45) and all-cause mortality (HR 2.96, 95% CI 1.89-4.64) compared to typical AF after adjustment for CHA2DS2-VASc score and age.
The type of clinical presentation may have important implications for the prognosis of new-onset AF in the community.
Atrial fibrillation (AF) is a life-complicating illness adversely affecting morbidity, health-related quality of life (HRQOL), and healthcare use. Studies using HRQOL instruments suggest that ...patients diagnosed with AF experience more psychological distress than do healthy controls. Psychological distress in forms of anxiety and depression in patients with heart failure or coronary artery disease is related to increased mortality, morbidity, and consumption of healthcare. However, there is a critical lack of knowledge regarding the type and extent of psychological distress and its consequences in patients diagnosed with AF. This article will review the current state of scientific knowledge regarding psychological distress in patients with AF and offer suggestions for future studies. Medline, CINAHL, PscyhInfo, and Psychology and Behavioral Sciences Collection databases up to June 2009 were reviewed for key terms atrial fibrillation, psychological distress, affective distress, mood, emotional distress, psychological stress, negative affect, anxiety, depression, anger, and hostility. Ten studies using tested instruments to measure psychological distress were retained. The prevalence of psychological distress was not consistently reported. Combined findings revealed that psychological distress in the form of depression and/or anxiety uniquely contributed to greater AF symptom severity, diminished HRQOL, and recurrence of AF. Studies describing interventions to address psychological distress were not found. Lack of conceptual clarity and diversity of study purposes, designs, participants, and instruments limit the ability to draw coherent conclusions from findings. Nevertheless, findings suggest that psychological distress is present in a substantial portion of patients diagnosed with AF and its presence is related to adverse outcomes. Further study to identify the prevalence, characteristics, and consequences of psychological distress in patients diagnosed with AF is required to extend our knowledge and provide a foundation for development of interventions to address psychological distress in this rapidly increasing population.
Aims and objectives
To describe patients’ experiences from symptom onset to initial treatment for atrial fibrillation.
Background
The estimated number of individuals with atrial fibrillation globally ...in 2010 was 33·5 million. World‐wide, each year, new cases of atrial fibrillation approach 5 million, and prevalence will increase 2·5‐fold by 2050. As a result, clinicians worldwide will treat a growing number of patients with atrial fibrillation. Early intervention to promote atrial fibrillation self‐management is critical to reduce associated complications of stroke and heart failure. Greater understanding of patients’ experiences from symptom onset to initial treatment for atrial fibrillation is needed to guide development of interventions to promote early effective self‐management.
Design
A descriptive qualitative design was used.
Methods
Twenty females and 21 males at an academic medical centre were interviewed using open‐ended questions to explore their experiences from symptom onset to initial treatment for atrial fibrillation. Data were analysed using qualitative content analysis.
Results
Participants’ mean age was 64·3 (SD = 10·1) years. Four themes were identified: (1) misinterpreting symptoms; (2) discovering the meaning of atrial fibrillation; (3) facing fears, uncertainty, and moving to acceptance; and (4) receiving validation and reassurance. Participants lacked knowledge of atrial fibrillation and took cues from providers’ responses to appraise symptoms and diagnosis. Fear and uncertainty were reduced when providers initiated prompt treatment and took time to explain atrial fibrillation. Patients appreciated receiving clear information about atrial fibrillation, were engaged in learning, and motivated to participate in their care.
Conclusions
Providers played a critical role in helping patients to develop an accurate understanding of atrial fibrillation, to cope with the new diagnosis, and motivated them to engage in effective self‐management.
Relevance to clinical practice
Insight into participant experiences from symptom onset to initial treatment for atrial fibrillation may inform development of interventions to promote effective atrial fibrillation self‐management.
Cardiac tachyarrhythmias are recurrent or chronic and in some cases life-threatening conditions. Heart rhythm disturbances are often highly symptomatic and the psychological impact of the disease can ...be significant. Patients' beliefs and knowledge about their health (and illness), medications, and healthcare they receive are important determinants of whether or not they accept recommended treatments; influence their coping responses to their illness and treatment; adherence to recommended therapy; and ultimately affects health outcomes. Incorporation of patients' values and preferences for therapy should now be considered as an integral part of the decision-making process and treatment strategy.
It is important to acknowledge and understand the impact of cardiac tachyarrhythmias on the patient. To address this issue, a Task Force was convened by the European Heart Rhythm Association (EHRA), and endorsed by the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS), and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE), with the remit to comprehensively review the published evidence available, to publish a joint consensus document on patient values and preferences for the management of cardiac tachyarrhythmias, and to provide up-to-date consensus recommendations for use in clinical practice.
Hence this unique consensus document focuses on patients, summarizing the available literature on patients' experiences of living with various cardiac tachyarrhythmias and their treatment preferences, and identifies gaps in knowledge which will help to inform clinical practice and future research. The document will also summarize key points for discussions with patients during consultations regarding their condition, treatment options, disease trajectory, treatment goals, and outcomes. Finally, this document provides links to useful resources and patient advocacy groups and organizations and professional societies relevant to each group of cardiac tachyarrhythmias.
Atrial fibrillation (AF) is a public health burden associated with stroke, cardiomyopathy, and diminished quality of life (QOL). Although surveys suggest that AF impairs physical functioning and ...mental health, little is known about patients' experiences contributing to those findings. Understanding patients' experiences of living with AF may provide a foundation for interventions to improve QOL. In this qualitative descriptive study, we describe the experience of living with recurrent symptomatic AF from patients' perspectives.
Seven women and 8 men, recruited from a Midwest medical center, with a mean age of 59.8 (SD, 14.5) years, diagnosed with recurrent symptomatic AF, participated in open-ended interviews. Data were analyzed by qualitative descriptive methods.
Themes were identified that reveal experiences of living with recurrent symptomatic AF over time and how AF may diminish QOL. Themes included (1) finding the meaning of symptoms, (2) feeling uninformed and unsupported, (3) turning points, (4) steering clear of AF, (5) managing unpredictable and function limiting symptoms, (6) emotional distress, and (7) accommodation to AF tempered with hope for a cure. Participants experienced delays in diagnosis and minimization of their concerns by clinicians and others and did not receive counseling regarding the nature of AF and self-management. Strategies to manage AF and its symptoms were learned through trial and error and were transiently effective. Support for coping with the emotional burden of AF was lacking. Interventions to improve recognition of AF symptoms and promote prompt evaluation and treatment are needed. Psychoeducational programs to teach patients and families about the nature of AF, guide self-management, and address the emotional burden of AF need to be developed and tested.
