Abstract
<strong>BACKGROUND</strong> There is a growing recognition of sex-related disparities in atrial fibrillation (AF). However, limited data is available in Chinese AF patients. <strong>MATERIAL AND METHODS</strong> We compared symptoms, quality of life (QoL), and treatment of AF according to sex from the China AF Registry study. <strong>RESULTS</strong> We studied 14 723 patients with non-valvular AF, of whom 5645 patients (38.3%) were female. Women were older than men (67.5±10.6 vs. 62.2±12.2). Compared to men, women had more comorbidities and a higher proportion of CHA₂DS₂-VASC score ≥2. Women with AF experienced more severe or disabling symptoms than men (33.7% vs. 22.9% in age <75 group; 40.3% vs. 28.7% in age ≥75 group; both P<0.0001). After multivariate analysis, women with AF still had lower QoL (OR 0.69; 95%CI, 0.63-0.76; P<0.0001). Women tended to have lower rates of ablation and rhythm-control drug use in those aged <75 years. Oral anticoagulant use was low and had no sex difference in AF patients with a CHA₂DS₂-VASC score ≥2. <strong>CONCLUSIONS</strong> In Chinese AF patients, women were older and more symptomatic, and had worse QoL. Despite all these differences, women tended to receive less rhythm-control treatment in those aged <75 years. Oral anticoagulant was substantially underused in high stroke risk patients, regardless of sex.

Abstract
Background The direct oral anticoagulants (DOACs) offer several advantages over warfarin in the management atrial fibrillation, including the provision of fixed dosing without a requirement for regular monitoring. Recently however the subject of DOAC monitoring has been probed after several post-hoc analyses demonstrated an association between plasma levels and efficacy and safety events. Objective The aim of this pilot study was to explore the acceptability of DOAC plasma monitoring amongst patients with atrial fibrillation and the factors that may influence these attitudes. Method A simple DOAC monitoring schedule based on the dabigatran pharmacokinetic profile was developed. A cross-sectional survey was distributed to patients with atrial fibrillation asking them to indicate their likelihood of taking a particular DOAC subjected to plasma monitoring. Results Thirty patients participated in the study. Most patients (63.3%) favoured taking a DOAC subjected to monitoring under the proposed schedule, citing increased efficacy and reduced toxicity as the reasons for their response. Conclusion There is some suggestion that atrial fibrillation patients may in fact favour taking a DOAC subjected to infrequent monitoring if this enhanced safety and efficacy.

Abstract
OBJECTIVE The aim of this study was to examine the association between medication adherence and illness perceptions, and to explore the factors associated with poor medication adherence in atrial fibrillation (AF) patients receiving direct oral anticoagulants (DOACs) in a real-world clinical setting. METHODS An observational cross-sectional pilot study was conducted at a single Japanese university hospital. One hundred and twenty-nine patients who were diagnosed with AF and who were taking DOACs were recruited from outpatients between January 4th and April 25th, 2017. We evaluated medication adherence to DOACs using the Morisky Medication Adherence Scale-8 (MMAS-8) and illness perceptions using the Brief Illness Perception Questionnaire (BIPQ). The patients' characteristics and clinical data were collected from electronic medical records. RESULTS Ninety-nine (76.7%) patients (male, n = 74; mean age, 71.4±9.8 years) participated in this study. According to the MMAS-8, 21 (21.2%) of the patients were classified into the poor adherence group (MMAS-8 score of <6), and 78 (78.8%) were classified into the good adherence group (MMAS-8 score of 6-8). A multivariate logistic regression analysis revealed that age (per year, odds ratio [OR] 0.912, 95% confidence interval [CI] 0.853-0.965, p = 0.001), a history of warfarin use (OR 0.181, 95% CI 0.033-0.764, p = 0.019), duration of DOAC exposure (per 100 days, OR 1.245, 95% CI 1.084-1.460, p = 0.001), and the BIPQ emotional response score (per 1 point, OR 1.235, 95% CI 1.015-1.527, p = 0.035) were significantly associated with poor medication adherence in AF patients receiving DOACs. CONCLUSION Poor medication adherence to DOACs was strongly associated with a stronger emotional response (i.e. stronger feelings of anger, anxiety, and depression), as well as younger age, the absence of a history of warfarin treatment, and longer DOAC exposure. Further evaluation of the factors associated with medication adherence in AF patients and the development and execution of strategies for improving poor adherence are warranted in the real-world clinical setting.

Abstract
BACKGROUND Depression is a frequently observed comorbid condition in patients with cardiovascular diseases. In contrast to coronary heart disease and heart failure there is a limited amount of published data concerning the increased prevalence of depression among patients with atrial fibrillation (AF). Therefore, we decided to assess the prevalence of depression in Polish community-dwelling older patients with a history of AF. METHODS The data were collected as part of the nationwide PolSenior project (2007-2012). Out of 4979 individuals (age range 65-104 years), data on self-reported history of AF were available for 4677 (93.9%). Finally, 4049 participants without suspected moderate or severe dementia in Mini Mental State Examination test were assessed with the 15-item Geriatric Depression Scale (GDS), and a score of 6 points and more was regarded as suspected depression. RESULTS Mean age (±SD) of the study population was 78.1 (±8.3) years; 52% were males. The history of AF was reported by 788 (19.5%) subjects. In the univariate analysis a self-reported AF history was associated with 42% increase of suspected depression (41% vs 29%; P < 0.001). In multivariate logistic regression AF remained an independent predictor of depression (OR = 1.69; 95%CI: 1.43-2.00), stronger than heart failure, diabetes or coronary heart disease. CONCLUSIONS In community-dwelling geriatric Polish population AF is associated with higher prevalence of depression. This association is independent from the demographic factors, disabilities and comorbidities (including history of stroke).

Abstract
Aims It is recommended to perform atrial fibrillation ablation with continuous anticoagulation. Continuous apixaban has not been tested. Methods and results We compared continuous apixaban (5 mg b.i.d.) to vitamin K antagonists (VKA, international normalized ratio 2-3) in atrial fibrillation patients at risk of stroke a prospective, open, multi-centre study with blinded outcome assessment. Primary outcome was a composite of death, stroke, or bleeding (Bleeding Academic Research Consortium 2-5). A high-resolution brain magnetic resonance imaging (MRI) sub-study quantified acute brain lesions. Cognitive function was assessed by Montreal Cognitive Assessment (MoCA) at baseline and at end of follow-up. Overall, 674 patients (median age 64 years, 33% female, 42% non-paroxysmal atrial fibrillation, 49 sites) were randomized; 633 received study drug and underwent ablation; 335 undertook MRI (25 sites, 323 analysable scans). The primary outcome was observed in 22/318 patients randomized to apixaban, and in 23/315 randomized to VKA {difference -0.38% [90% confidence interval (CI) -4.0%, 3.3%], non-inferiority P = 0.0002 at the pre-specified absolute margin of 0.075}, including 2 (0.3%) deaths, 2 (0.3%) strokes, and 24 (3.8%) ISTH major bleeds. Acute small brain lesions were found in a similar number of patients in each arm [apixaban 44/162 (27.2%); VKA 40/161 (24.8%); P = 0.64]. Cognitive function increased at the end of follow-up (median 1 MoCA unit; P = 0.005) without differences between study groups. Conclusions Continuous apixaban is safe and effective in patients undergoing atrial fibrillation ablation at risk of stroke with respect to bleeding, stroke, and cognitive function. Further research is needed to reduce ablation-related acute brain lesions.

Abstract
Atrial fibrillation (AF) is more prevalent in older adults than other populations and affects health-related quality of life (HRQoL). However, few studies have investigated HRQoL and clinical factors in older adults with AF. The aim of the current cross-sectional study was to describe HRQoL using an AF-specific QoL instrument and identify factors influencing HRQoL in Korean older adults with AF. Data from 205 patients diagnosed with AF in a tertiary hospital were analyzed. Patients' mean age was 74.24 years and 43.9% of patients were female. The total HRQoL score was 49.6 of 100. The lowest score was in the physical dimension of HRQoL. Concern about lethal complications from AF was an essential concept related to QoL. In multiple linear regression, age and gender were significant predictors for the physical dimension of HRQoL. Gender and comorbidity were significant factors for the sexual activity dimension. Health care providers should help improve the HRQoL of older adults with AF by reducing physical burdens and concerns about health-related complications. [Res Gerontol Nurs. 2018; 11(4):207-215.].

Abstract
OBJECTIVE To describe self-reported disease understanding for newly diagnosed patients with atrial fibrillation (AF) and assess (1) how disease understanding changes over the first 6 months after diagnosis and (2) the relationship between patient understanding of therapies at baseline and treatment receipt at 6 months among treatment-naïve patients. METHODS We analysed survey data from SATELLITE (Survey of Patient Knowledge and Personal Priorities for Treatment), a substudy of patients with new-onset AF enrolled in the national Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT) II registry across 56 US sites. Patients were surveyed at the baseline and 6-month follow-up clinic visits using Likert scales. RESULTS Among 1004 baseline survey responses, patients' confidence in their understanding of rhythm control, ablation, anticoagulation and cardioversion was suboptimal, with 'high' understanding ranging from 8.5% for left atrial appendage closure to 71.3% for rhythm therapy. Of medical history and demographic factors, education level was the strongest predictor of reporting 'high' disease understanding. Among the 786 patients with 6-month survey data, significant increases in the proportion reporting high understanding were observed (p<0.05) only for warfarin and direct oral anticoagulants (DOACs). With the exception of ablation, high understanding for a given therapeutic option was not associated with increased use of that therapy at 6 months. CONCLUSIONS About half of patients with new-onset AF understood the benefits of oral anticoagulant at the time of diagnosis and understanding improved over the first 6 months. However, understanding of AF treatment remains suboptimal at 6 months. Our results suggest a need for ongoing patient education. CLINICAL TRIAL REGISTRATION Clinicaltrials.gov.

Abstract
BACKGROUND Improvement in health-related quality of life is a key therapeutic goal of disease management in atrial fibrillation (AF). OBJECTIVES To describe the development of the AFImpact, an AF-specific health-related quality-of-life patient-reported outcome measure. METHODS Development and validation of the AFImpact comprised a qualitative stage, consisting of a literature review and concept elicitation interviews (91 patients with AF), item generation, and cognitive debriefing (30 patients with AF), and a quantitative stage, consisting of evaluation of the instrument's psychometric properties (313 patients with AF). Preliminary responsiveness to change was assessed in 118 patients undergoing cardioversion. RESULTS On the basis of the literature review and concept elicitation interviews, 75 items were generated. Factor analyses guided a reduction to 18 items. Three domains were confirmed: vitality (7 items), emotional distress (8 items), and sleep (3 items). The 18-item AFImpact demonstrated high item convergent and discriminant validity. Cronbach α coefficients showed high internal consistency reliability. Test-retest reliability of individual items in stable patients (n = 33) was satisfactory, with intraclass correlation coefficients ranging from 0.61 to 0.86. All three AFImpact domain scores differentiated patients who reported different levels of overall health, thereby supporting known-groups validity. Scores for each item improved after cardioversion, with effect sizes ranging from -0.19 to -0.65. CONCLUSIONS Psychometric evaluations support the reliability and validity of the AFImpact as a patient-reported outcome instrument to measure the impact of AF, with preliminary results in patients undergoing cardioversion supporting responsiveness to change.

Abstract
BACKGROUND Atrial fibrillation (AF) and dementia are largely prevalent and incident in progressively older subjects, suggesting a link between the two conditions. While in the general population there are several findings supporting a causal relationship between AF and dementia, it is unclear whether or not this association is still present in individuals aged 80 and older. RESULTS So far, the few studies that analysed this issue did not provide enough evidence supporting the causative role of AF in increasing the risk of cognitive decline or dementia in patients aged 80 and older. Conversely, a relevant role of optimal anticoagulation control in determining a significant reduction in the risk of cognitive decline is suggested, in AF subjects aged 80years or older. CONCLUSIONS Further data, coming from population-based studies specifically investigating very old individuals and based upon large samples and comprehensive cognitive assessments, are needed to fully elucidate the relationship between AF and dementia in very old individuals.

Abstract
BACKGROUND For both patients and clinicians, differences between older and new anticoagulants have major implications for treatment selection, day-to-day management of therapy and adherence. AIMS To explore patients' preferences for warfarin versus direct oral anticoagulant (DOAC) therapy. METHODS Mixed-method study involving anticoagulated older patients admitted to hospital. Part A comprised a vignette-based questionnaire; patients were asked whether they preferred Medicine A (warfarin) or Medicine B (DOAC). Part B interviews explored patients' satisfaction with their current anticoagulant. Responses were thematically analysed. RESULTS Forty patients participated: 23 warfarin-treated, 17 DOAC-treated. Collectively, Parts A and B identified that most patients were satisfied with their current therapy (warfarin or DOAC), expressing reluctance to change to alternatives. Among patients who were able to numerically rate their satisfaction with therapy, most were 'satisfied' with their current anticoagulant, although warfarin-treated patients were slightly less 'satisfied' (median score 3.5) than those on DOACs (median score 5.0). Despite this, warfarin-treated patients still preferred their current therapy (over DOACs) due to familiarity and the security of regular international normalised ratio (INR) monitoring; those who preferred DOACs cited previous warfarin-related bleeding and unstable INRs as key reasons. DOAC-treated patients who preferred warfarin perceived regular monitoring as a major advantage; only those having had negative experiences with warfarin clearly preferred DOACs. CONCLUSION Most patients accepted their currently prescribed anticoagulant, be it warfarin or DOACs. Features of specific anticoagulants, such as regular monitoring with warfarin, were perceived variably - some patients cited them as advantages and others as disadvantages. The clearest preference identified was for the agent already being taken.

Abstract
Involuntary unemployment due to job loss has been associated with increased risk of cardiovascular events. Whether it also is associated with increased risk of atrial fibrillation (AF) is currently unknown. Therefore, we examined this association in 8,812 participants residing mainly in the Southeastern United States (mean age 58.1 ± 7.8 years; 63.2%; women; 43.2% black) with data on employment status who were enrolled in the REasons for Geographic And Racial Differences in Stroke study between 2003 and 2007 after excluding those with voluntary unemployment (retiree, homemakers, and students). AF was identified by electrocardiogram and past medical history at the same period. The cross-sectional association between status and type of unemployment with AF was examined in multivariable logistic regression models. Additional analysis in 4,273 participants without baseline AF and with data on incident AF collected in a follow-up visit occurred after a median of 9.4 years from baseline was also conducted. In a model adjusted for socio-demographics, health insurance, income, perceived stress, and cardiovascular risk factors, unemployment was associated with 60% increased odds of AF (odds ratio [95% confidence interval] 1.60 (1.24, 2.07)). This association was consistent in subgroups stratified by median age, gender, race, education, income, and health insurance status. Similarly, unemployment was associated with AF in those without AF at baseline who developed incident AF (odds ratio [95% confidence interval] 1.54 (1.04, 2.37)). In conclusion, involuntary unemployment is associated with increased risk of AF. This may call for considering socioeconomic determinants such as unemployment as part of the preventive strategies for AF.

Abstract
OBJECTIVE Oral anticoagulation (OAC) is state-of-the-art therapy for atrial fibrillation (AF), the most common arrhythmia worldwide. However, little is known about the perception of patients with AF and how it correlates with risk scores used by their physicians. Therefore, we correlated patients' estimates of their own stroke and bleeding risk with the objectively predicted individual risk using CHA2DS2-VASc and HAS-BLED scores. DESIGN Cross-sectional prevalence study using convenience sampling and telephone follow-up. SETTINGS Eight hospital departments and one general practitioner in Austria. Patients' perception of stroke and bleeding risk was opposed to commonly used risk scoring. PARTICIPANTS Patients with newly diagnosed AF and indication for anticoagulation. MAIN OUTCOME MEASURES Comparison of subjective risk perception with CHA2DS2-VASc and HAS-BLED scores showing possible discrepancies between subjective and objective risk estimation. Patients' judgement of their own knowledge on AF and education were also correlated with accuracy of subjective risk appraisal. RESULTS Ninety-one patients (age 73±11 years, 45% female) were included in this study. Subjective stroke and bleeding risk estimation did not correlate with risk scores (ρ=0.08 and ρ=0.17). The majority of patients (57%) underestimated the individual stroke risk. Patients feared stroke more than bleeding (67% vs 10%). There was no relationship between accurate perception of stroke and bleeding risks and education level. However, we found a correlation between the patients' judgement of their own knowledge of AF and correct assessment of individual stroke risk (ρ=0.24, p=0.02). During follow-up, patients experienced the following events: death (n=5), stroke (n=2), bleeding (n=1). OAC discontinuation rate despite indication was 3%. CONCLUSIONS In this cross-sectional analysis of OAC-naive patients with AF, we found major differences between patients' perceptions and physicians' assessments of risks and benefits of OAC. To ensure shared decision-making and informed consent, more attention should be given to evidence-based and useful communication strategies. TRIAL REGISTRATION NUMBER NCT03061123.

Abstract
AIMS To assess whether AF is a risk factor for cognitive dysfunction we used prospective data on AF, repeat cognitive scores, and dementia incidence in adults followed over 45 to 85 years. METHODS AND RESULTS Data are drawn from the Whitehall II study, N = 10 308 at study recruitment in 1985. A battery of cognitive tests was administered four times (1997-2013) to 7428 participants (414 cases of AF), aged 45-69 years in 1997. Compared with AF-free participants, those with longer exposure to AF (5, 10, or 15 years) experienced faster cognitive decline after adjustment for sociodemographic, behavioural, and chronic diseases (P for trend = 0.01). Incident stroke or coronary heart disease individually did not explain the excess cognitive decline; however, this relationship was impacted when considering them together (P for trend 0.09). Analysis of incident dementia (N = 274/9302 without AF; N = 50/912 with AF) showed AF was associated with higher risk of dementia in Cox regression adjusted for sociodemographic factors, health behaviours and chronic diseases [hazard ratio (HR): 1.87; 95% confidence interval (CI): 1.37, 2.55]. Multistate models showed AF to increase risk of dementia in those free of stroke (HR: 1.67; 95% CI: 1.17, 2.38) but not those free of stroke and coronary heart disease (HR: 1.29; 95% CI: 0.74, 2.24) over the follow-up. CONCLUSION In adults aged 45-85 years AF is associated with accelerated cognitive decline and higher risk of dementia even at ages when AF incidence is low. At least in part, this was explained by incident cardiovascular disease in patients with AF.

Abstract
INTRODUCTION Atrial fibrillation is the most common sustained cardiac rhythm disturbance encountered in clinical practice. Despite its high prevalence and the associated high number of hospital admissions, few studies document the actual impact of atrial fibrillation on the patient. PURPOSE The purpose of this study was to describe the health-related quality of life (HRQOL) and to examine the impact of seriousness of illness on HRQOL in patients newly diagnosed with atrial fibrillation. METHODS AND RESULTS A descriptive correlational and cross-sectional survey study included 81 subjects newly diagnosed with atrial fibrillation within 6 months prior to data collection through face-to-face interview by the Atrial Fibrillation Symptom Frequency and severity checklist (SCL) and the short form-36 health survey (SF-36). As the variables for HRQOL, subjects' perception of both physical health and mental health was poorer than that of general US population. The seriousness of illness had a significant inverse relationship with HRQOL, including both physical health and mental health. CONCLUSION The findings of this study indicated that the HRQOL in patients newly diagnosed with atrial fibrillation was significantly impaired and the subjective seriousness of illness had a pivotal impact on HRQOL in atrial fibrillation.

Abstract
CONTEXT Direct oral anticoagulants (DOACs) may be as effective as, and at times safer than, warfarin. Because DOACs do not require regular serum level monitoring, patients' interaction with the health care system may be reduced. To the authors' knowledge, although studies have evaluated warfarin adherence, few studies have evaluated the real-world adherence to DOACs. OBJECTIVE To evaluate whether a difference exists between medication adherence of patients taking DOACs vs patients taking warfarin. METHODS The electronic medical records of the Anticoagulation Clinic database at Mayo Clinic in Scottsdale, Arizona, were reviewed. Inclusion criteria were adults taking DOACs and a matching cohort taking warfarin between January 1, 2011, and December 30, 2013. The Morisky Medication Adherence Scale-8 item, a validated medication adherence tool, was used to evaluate adherence in both cohorts, and the qualitative covariates were analyzed using ordinal logistic regression. RESULTS Of 324 surveys that were sent, 110 patients (34.0%) responded. Most patients took DOACs for atrial fibrillation, and few took DOACs for venous thromboembolism. Overall, 60 of 66 patients (90.9%) in the DOAC group and 42 of 44 patients (95.5%) in the warfarin group reported medium or high adherence. Difference in adherence scores between the 2 groups was not statistically significant (P=.8). CONCLUSION Similar adherence was noted between DOACs and warfarin regardless of the frequency of serum level monitoring.

Abstract
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.

Abstract
BACKGROUND The increased risk of stroke and cognitive impairment associated with atrial fibrillation (AF) is well documented. However, there is a paucity of research investigating the relations between AF and brain morphology. OBJECTIVE The purpose of this study was to investigate the association between AF and brain volume measures on magnetic resonance imaging (MRI). METHODS The study sample included stroke- and dementia-free participants who attended the Framingham Heart Study offspring cohort 7th examination cycle (1999-2005) and underwent contemporaneous MRI. We examined the association between prevalent AF and brain volume measures (total cerebral volume, frontal lobe volume, temporal lobe volume, temporal horn volume, hippocampal volume, and white matter hyperintensity volume) with linear regression. We first adjusted models for age and sex, and then for vascular risk factors and APOE4. RESULTS We studied 2144 individuals (mean age 61.8 ± 9.3 years; 54% women); 73 participants (3.4%) had prevalent AF at the time of MRI. In age- and sex-adjusted models, AF was inversely associated with total cerebral brain volume, frontal brain volume, and temporal brain volume. After further adjustment for vascular risk factors and APOE4, AF remained associated with frontal brain volume. CONCLUSION After accounting for vascular risk factor burden, prevalent AF was associated with lobar indexes of vascular brain aging but not with expected white matter changes.

Abstract
Background—
Despite its therapeutic efficacy, warfarin is extremely underused in Chinese patients with nonvalvular atrial fibrillation (AF). Whether the nonpersistence of warfarin treatment contributes to its underuse is not known. The aims of this study were to determine nonpersistence rates of newly started warfarin treatment in Chinese patients with nonvalvular AF and to identify the factors associated with discontinuation of the treatment.
Methods and Results—
We identified 1461 patients with nonvalvular AF enrolled in the Chinese Atrial Fibrillation Registry (CAFR) who newly started on warfarin therapy in the period between August 1, 2011, and June 30, 2014. During a follow-up of 426±232 days, 22.1% of patients discontinued warfarin within 3 months, 44.4% within 1 year, and 57.6% within 2 years of initiation of therapy. Patients with no or partial insurance coverage had a higher likelihood to discontinue warfarin than those with full insurance coverage (adjusted hazard ratio 1.65, 95% confidence interval [1.03–2.64];
P
=0.038 and 1.66 [1.13–2.42];
P
=0.009, respectively). Paroxysmal AF (1.56 [1.28–1.92];
P
<0.0001), no prior stroke/transient ischemic attack/thromboembolism (1.60 [1.24–2.05];
P
=0.0003), and no dyslipidemia (1.34 [1.06–1.70];
P
=0.016) were also found to be independent predictors for nonpersistence of warfarin therapy.
Conclusions—
Nonpersistence of warfarin treatment becomes a serious problem for stroke prevention in Chinese patients with nonvalvular AF. Our findings can be used to identify patients who require closer attention or to develop better management strategy for oral anticoagulation therapy.

Abstract
The aim of this descriptive, correlational, and cross-sectional survey was to explore uncertainty in patients with atrial fibrillation and to examine the relationships between uncertainty and its antecedents, including education, social support, and perceived seriousness of illness in patients newly diagnosed with atrial fibrillation. The theoretical framework of the study was Mishel’s middle-range nursing theory of uncertainty in illness. A convenience sample of 81 participants recruited from two academic medical centers over 10 months was interviewed. Uncertainty was moderately high in patients with atrial fibrillation compared to other clinical populations. Among antecedents of uncertainty, higher education was significantly associated with less uncertainty (= -.21 to -.25). Except for tangible support, persons with greater social supports perceived less uncertainty (= -.25 to -.27), and individuals with greater perceived seriousness of illness reported greater uncertainty (= .30 to .33).
