Regional variation in quality of life in patients with a Fontan circulation: A multinational perspective

Wellbeing in Children and Adolescents with Fontan Physiology

OBJECTIVE

To assess health-related quality of life (HRQOL) and global quality of life (QOL) in children and adolescents with Fontan physiology and identify key predictors influencing these outcomes.

STUDY DESIGN

Cross-sectional analysis of 73 children and adolescents enrolled in the Australia and New Zealand Fontan Registry aged 6-17 years, at least 12 months post-Fontan operation. Assessments included the Pediatric Quality of Life Inventory (PedsQL) for HRQOL and a developmentally-tailored visual analogue scale (0-10) for global QOL, along with validated sociodemographic, clinical, psychological, relational, and parental measures. Clinical data were provided by the Australia and New Zealand Fontan Registry.

RESULTS

Participants (mean age: 11.5 ± 2.6 years, 62% male) reported lower overall HRQOL (P < .001), and lower scores across all HRQOL domains (all P < .0001), compared with normative data. Median global QOL score was 7.0 (IQR 5.8-8.0), with most participants (79%) rating their global QOL ≥6. Anxiety and depressive symptoms requiring clinical assessment were reported by 21% and 26% of participants, respectively. Age, sex, and perceived seriousness of congenital heart disease explained 15% of the variation in HRQOL scores, while depressive symptoms and treatment-related anxiety explained an additional 37% (final model: 52% of variance explained). For global QOL, sociodemographic and clinical factors explained 13% of the variance in scores, while depressive symptoms explained a further 25% (final model: 38% of variance explained). Parental factors were not associated with child QOL outcomes.

CONCLUSIONS

Children and adolescents with Fontan physiology experience lower HRQOL than community-based norms, despite reporting fair overall QOL. Psychological factors predominantly influenced QOL outcomes, indicating strategies to bolster psychological health could improve QOL in this population.

Quality of Life and Well-Being in Adults With Fontan Physiology: Findings From the Australian and New Zealand Fontan Registry Quality of Life Study

BACKGROUND

To characterize global and health-related quality of life (QOL) among adults with Fontan physiology enrolled in the Australian and New Zealand Fontan Registry (ANZFR), and identify sociodemographic, clinical, psychological, and relational factors associated with outcomes.

METHODS AND RESULTS

Using a cross-sectional survey design, 66 adults with Fontan physiology (58% women; mean age, 29.6±7.7 years; range, 18-50 years) completed validated self-report measures. Health-related QOL was assessed using the Pediatric Quality of Life Inventory, and global QOL was assessed using a visual analog scale (0-10). Participants reported lower total health-related QOL (P<0.001), as well as lower physical (P<0.001) and social (P=0.002) functioning compared with normative data. Median global QOL was 7.0 (interquartile range: 5.0-8.0) and most participants (71%) rated their QOL ≥6. For health-related QOL, age, sex, university education, and length of hospital stay in the past 12 months explained 27% of the variance in scores, while general psychological stress, medical traumatic stress, communication problems, and access to emotional support explained a further 44% of variance (final model: 71% of variance explained). For global QOL, sociodemographic and clinical factors explained 20% of the variance in scores, while psychological stress and sense of coherence explained a further 24% (final model: 44% of variance explained).

CONCLUSIONS

Adults with Fontan physiology reported lower overall health-related QOL compared with community-based norms. Variance in QOL outcomes were predominantly attributable to psychological and relational factors. Tailored screening and assessment to identify Fontan patients at greatest risk of lower QOL, and a proactive approach to supportive care, are needed.

The Relationship Between Perceived Parenting Practices and Anxiety in Adults With Congenital Heart Disease

BACKGROUND

Patients with congenital heart disease (CHD) and their parents face challenges throughout their lives that can lead to anxiety lasting into adulthood. We aim to assess the association between perceived parenting practices and anxiety beyond paediatric medical-surgical histories in adults with CHD.

METHODS

A cross-sectional study of adults with CHD was conducted at the Montreal Heart Institute (MHI). Perception of parental practices during childhood was retrospectively assessed with the use of validated self-report questionnaires, and anxiety in adulthood was assessed with the use of the Hospital Anxiety and Depression Scale. Sociodemographic and medical information were collected from a questionnaire and medical records. Hierarchic multiple linear regression was conducted.

RESULTS

Of the 223 participants, the mean age was 46 ± 14 years and 59% were female. Perceived parenting practices explained more variance (11%) in the anxiety score than paediatric medical-surgical history (2%). In our final model, anxiety was significantly associated with age, parental history of anxiety, and positive parenting practices, but not with overprotection.

CONCLUSIONS

Parenting practices are associated with anxiety in adults with CHD beyond paediatric medical-surgical history and sociodemographic. Positive parenting practices may be protective against anxiety in adulthood. Longitudinal studies are needed to determine causality.

Age moderates change in disease-related stress among congenital heart disease survivors: a 6-year follow-up

AIMS

As congenital heart disease (CHD) survivors age, they are confronted with elevated risk of cardiovascular morbidity and increasingly complex disease self-management demands. Given that stress is associated with poor physical and psychosocial outcomes, it is crucial to examine how disease-related stress changes over time in this population. However, this outcome has received little research attention to date. This study aimed to identify demographic and clinical predictors of change in disease-related stress over 6 years among CHD survivors.

METHODS AND RESULTS

Congenital heart disease survivors (N = 252, Mage = 25.6 ± 7.1, 52.9% female) completed the first 13 items of the Responses to Stress Questionnaire, adapted for use among CHD survivors, to assess disease-related stressors at study entry (T1) and 6-year follow-up (T2). Age, gender, estimated family income, and New York Heart Association (NYHA) functional class at T1 were entered into mixed linear models to determine their impact on change in disease-related stress. Older age (P < 0.001), lower income (P < 0.001), and presence of functional limitations (NYHA ≥ II) (P < 0.001) predicted greater increases in disease-related stress. When controlling for NYHA, functional class, and income, a significant time by age interaction was identified such that disease-related stress increased over time among those who were adolescents at T1 [b = 4.20, P = 0.010, 95% confidence interval (1.01, 7.40)], but remained stable among young adults.

CONCLUSION

The transition from adolescence to adulthood may be a period of increasing disease-related stress. Healthcare providers should consider screening adolescents for elevated disease-related stress during transition education and provide resources to bolster resilience.

The Influence of Illness Perception and Coping on Anxiety in Adults With Congenital Heart Disease

Background

Up to one-half of adults with congenital heart disease (CHD) experience psychological distress, including anxiety.

Objectives

This paper sought to: 1) assess the contribution of illness perception in explaining anxiety symptoms beyond sociodemographic and medical variables in adults with CHD; and 2) investigate the potential mediating effect of coping style.

Methods

CHD adult patients were recruited at Montreal Heart Institute between June 2019 and April 2021 for this cross-sectional study. Participants responded to self-reported questionnaires (Hospital Anxiety and Depression Scale, Brief Illness Perception Questionnaire, and Brief COPE). Medical characteristics (CHD complexity, NYHA functional class, and cardiac devices) were collected from medical records. We conducted hierarchical multiple linear regression and mediation analyses.

Results

Of the 223 participants (mean age 46 ± 14 years, 59% women), 15% had clinically significant anxiety symptoms. Medical and sociodemographic variables explained 15% of the variation in anxiety symptoms. Adding illness perception explained an additional 18% of the variation in anxiety. This R2 change was significant (F[1,188] = 49.06, P < 0.0001). Illness perception explained more variance (18%) than medical and sociodemographic variables combined. A more threatening perception of illness was associated with greater anxiety symptoms (β = 0.45, P < 0.0001). Furthermore, illness perception was associated with coping, which was linked to reduced anxiety symptoms. Coping response style accounted for 20% of the total effect of illness perception on anxiety.

Conclusions

Illness perception and coping are associated with anxiety in adults with CHD. Future initiatives should assess whether targeting these potentially modifiable factors effectively prevents or mitigates anxious symptoms in adults with CHD.

The Australian and New Zealand Fontan Registry Quality of Life Study: Protocol for a population-based assessment of quality of life among people with a Fontan circulation, their parents, and siblings

INTRODUCTION

Advances in the care of patients with single-ventricle congenital heart disease have led to a new generation of individuals living with a Fontan circulation. For people with Fontan physiology, physical, psychological and neurodevelopmental challenges are common. The objective of this study is to describe and develop a deeper understanding of the factors that contribute to quality of life (QOL) among children, adolescents and adults living with a Fontan circulation across Australia and New Zealand, their parents and siblings.

METHODS AND ANALYSIS

This article presents the protocol for the Australian and New Zealand Fontan Registry (ANZFR) QOL Study, a cross-sectional, population-based study designed to examine QOL among people of all ages with a Fontan circulation, their parents and siblings. Study eligibility criteria includes (1) individuals with a Fontan circulation aged ≥6 years, at least 12 months post-Fontan procedure and enrolled in the ANZFR; (2) parents of individuals enrolled in the ANZFR; and (3) siblings aged ≥6 years of an individual enrolled in the ANZFR. A novel, online research platform is used to distribute personalised assessments tailored to participant age and developmental stage. A suite of validated psychometric self-report and parent-proxy report instruments capture potential correlates and predictors of QOL, including symptoms of psychological distress, personality attributes, coping and cognitive appraisals, family functioning, healthcare experiences and costs, access to emotional support and socioeconomic factors. Clinical characteristics are captured via self-report and parent-proxy report, as well as the ANZFR. Descriptive analyses and multilevel models will be used to examine QOL across groups and to investigate potential explanatory variables.

ETHICS AND DISSEMINATION

Approval has been obtained from all relevant Human Research Ethics Committees (HRECs), including the Sydney Children's Hospitals Network and the Royal Children's Hospital Melbourne HRECs. Study findings will be published in peer-reviewed journals and presented at national and international meetings and seminars.

Quality of life and other patient-reported outcomes across the lifespan among people with Fontan palliation

Traditional congenital heart disease (CHD) outcomes include mortality (survival to adulthood and life expectancy) as well as cardiac and non-cardiac morbidity. Strategies to identify and manage sequelae have primarily focused on objective data obtained though invasive and non-invasive diagnostic approaches. In contrast, patient-reported outcomes (PROs) provide subjective information, using standardized measures, about patients' health and wellbeing as reported directly by patients, without interpretation, interference, or assumptions made by clinicians or others. Selection of PRO measures entails thoughtful consideration of who the individuals being surveyed are, why assessment is occurring (e.g., what are the domains of interest; clinical vs. research), and what processes are in place for acquisition, administration, interpretation, and response. In this review, we focus on three domains of PROs for pediatric and adult patients with Fontan physiology: physical health status, psychological functioning, and quality of life (QOL). Infants, children, adolescents, and adults with CHD face a spectrum of challenges that may influence PROs across the lifespan. In general, patients with Fontan palliation tend to have lower physical health status, experience more psychological distress, and have equivalent or reduced QOL compared to healthy peers. Herein, we provide an overview of PROs among people with Fontan circulation as a group, yet simultaneously emphasize that the optimal way to understand the experiences of any individual patient is to ask and listen. We also offer clinical and research initiatives to improve the adoption and utility of PROs in CHD settings, which demonstrate commitment to capturing, understanding, and responding to the patient voice.

Quality of life of adult Fontan patients

BACKGROUND

Progress in the management of complex congenital heart disease (CHD) led to an improvement in survival rates of adults with a Fontan-like circulation. The objective of this study was to assess the subjective health status and quality of life of this population.

METHODS AND RESULTS

Patients aged more than 18 years at the time of the study, who underwent a Fontan-like procedure. Subjective health status was assessed by the SF-36 questionnaire and a linear analog scale was used to score patients' self-perception of their quality of life; cardiac and demographic parameters were collected.

RESULTS

Among 65 eligible patients, 60 (23 females; mean ± SD age: 25.7 ± 7.2 years) answered the SF-36 questionnaire and 46 of these were interviewed to evaluate their perceived quality of life. Among them, 20 (33.3%) were working full-time and 21 (35%) experienced arrhythmias. The physical SF-36 scores were lower in patients than in the general population (p ≤ 0.05). The New York Hear Association (NYHA) class and occupation were correlated with SF-36 scores of physical activity (respectively, p = 0.0001 and p = 0.025). SF-36 scores of psychological status were associated with the number of drugs and occupation (respectively, p = 0.0001 and p = 0.02). The mean ± SD quality of life score measured using a linear analog scale was 7.02 ± 1.6 and was linked to education and occupation (p ≤ 0.05) but not with cardiac parameters.

CONCLUSION

Adult Fontan patients perceive an impaired physical health but report a good overall quality of life. Education and occupation impacts significantly on Fontan patients' quality of life.

Atrial arrhythmias and patient-reported outcomes in adults with congenital heart disease: An international study

BACKGROUND

Atrial arrhythmias (ie, intra-atrial reentrant tachycardia and atrial fibrillation) are a leading cause of morbidity and hospitalization in adults with congenital heart disease (CHD). Little is known about their effect on quality of life and other patient-reported outcomes (PROs) in adults with CHD.

OBJECTIVE

The purpose of this study was to assess the impact of atrial arrhythmias on PROs in adults with CHD and explore geographic variations.

METHODS

Associations between atrial arrhythmias and PROs were assessed in a cross-sectional study of adults with CHD from 15 countries spanning 5 continents. A propensity-based matching weight analysis was performed to compare quality of life, perceived health status, psychological distress, sense of coherence, and illness perception in patients with and those without atrial arrhythmias.

RESULTS

A total of 4028 adults with CHD were enrolled, 707 (17.6%) of whom had atrial arrhythmias. After applying matching weights, patients with and those without atrial arrhythmias were comparable with regard to age (mean 40.1 vs 40.2 years), demographic variables (52.5% vs 52.2% women), and complexity of CHD (15.9% simple, 44.8% moderate, and 39.2% complex in both groups). Patients with atrial arrhythmias had significantly worse PRO scores with respect to quality of life, perceived health status, psychological distress (ie, depression), and illness perception. A summary score that combines all PRO measures was significantly lower in patients with atrial arrhythmias (-3.3%; P = .0006). Differences in PROs were consistent across geographic regions.

CONCLUSION

Atrial arrhythmias in adults with CHD are associated with an adverse impact on a broad range of PROs consistently across various geographic regions.

Physical Functioning, Mental Health, and Quality of Life in Different Congenital Heart Defects: Comparative Analysis in 3538 Patients From 15 Countries

BACKGROUND

We compared physical functioning, mental health, and quality of life (QoL) of patients with different subtypes of congenital heart disease (CHD) in a large international sample and investigated the role of functional class in explaining the variance in outcomes across heart defects.

METHODS

In the cross-sectional Assessment of Patterns of Patient-Reported Outcome in Adults with Congenital Heart Disease-International Study (APPROACH-IS), we enrolled 4028 adult patients with CHD from 15 countries. Diagnostic groups with at least 50 patients were included in these analyses, yielding a sample of 3538 patients (median age: 32 years; 52% women). Physical functioning, mental health, and QoL were measured with the SF-12 health status survey, Hospital Anxiety and Depression Scale (HADS), linear analog scale (LAS) and Satisfaction with Life Scale, respectively. Functional class was assessed using the patient-reported New York Heart Association (NYHA) class. Multivariable general linear mixed models were applied to assess the relationship between the type of CHD and patient-reported outcomes, adjusted for patient characteristics, and with country as random effect.

RESULTS

Patients with coarctation of the aorta and those with isolated aortic valve disease reported the best physical functioning, mental health, and QoL. Patients with cyanotic heart disease or Eisenmenger syndrome had worst outcomes. The differences were statistically significant, above and beyond other patient characteristics. However, the explained variances were small (0.6% to 4.1%) and decreased further when functional status was added to the models (0.4% to 0.9%).

CONCLUSIONS

Some types of CHD predict worse patient-reported outcomes. However, it appears that it is the functional status associated with the heart defect rather than the heart defect itself that shapes the outcomes.

Trends in the Prevalence of Atrial Septal Defect and Its Associated Factors among Congenital Heart Disease Patients in Vietnam

Atrial septal defect (ASD) is a non-physiologic communication between the two atria, allowing the shunt between systemic and pulmonary circulation. Data about ASD prevalence among congenital heart disease patients (CHD) in Vietnam are still scarce. We aim to assess the trends in the prevalence of ASD patients and associated factors among CHD patients. This was a cross-sectional study, with data collected from medical records from 1220 CHD patients in Da Nang hospital from 1 January 2010 to 31 December 2015. Descriptive statistics were used to estimate the prevalence of ASD among CHD patients. Comparative statistical methods were used to compare groups and logistic regression to access associated factors with ASD. The overall prevalence of ASD among CHD patients was 18.5% between 2010 and 2015. The prevalence varied between periods, ranging between 15% and 31.9% during the period. The prevalence of ASD women among CHD (25.9%) was significantly higher than for men (16.0%). The prevalence of ASD increased gradually when the age group increased. The factors associated with increased ASD prevalence were being a female and being in an older age group. The findings suggest that targeted policy should provide more-specific health-care services of ASD for women and older patients.

Management of the adult Fontan patient

Adults with congenital heart disease who underwent the Fontan operation to palliate single ventricle heart defects—by direct connection of caval venous return to the pulmonary circulation—have improved survival due to advancements in surgical and interventional techniques. However, cardiac and non-cardiac comorbidities often coexist, complicating management, and contributing to premature morbidity and mortality. Cardiac issues include heart failure symptoms related to systolic and diastolic dysfunction, atrial and ventricular arrhythmias and systemic atrioventricular valve regurgitation. Structural issues may be related to obstruction of the Fontan pathway, or to branch pulmonary artery stenosis, both of which exacerbate symptoms. Non-cardiac complications in adults involve hepatic congestion, fibrosis and cirrhosis, hepatocellular carcinoma, chronic kidney disease, stroke, venous stasis, lymphatic issues and involvement of other organ systems. ‘Fontan failure’ refers to circulatory dysfunction, either cardiac, non-cardiac, or both, diagnosed after exclusion or treatment of reversible contributors such as structural issues and arrhythmias. Counselling about reproductive health, mental health, perioperative management and overall wellness are paramount for patients’ well-being. Fontan patients are typically managed in highly specialised adult congenital heart centres, but may present to cardiologists or other practitioners with cardiac and non-cardiac emergencies or urgencies, sometimes after being out of care. In this review, we discuss the management of the adult Fontan patient, including surveillance, cardiac and non-cardiac complications, reproductive health, and advanced therapies.

Quality-of-life research in adult patients with congenital heart disease: current status and the way forward

Over the past four decades, the number of papers on quality of life (QoL) in congenital heart disease (CHD) has grown exponentially. However, firm conclusions have been hard to draw, because conceptual issues occurred and methodological differences prevented direct comparisons of studies. In general, QoL in CHD patients is good and it can be even better than in healthy peers when measured as life satisfaction. When QoL is measured as physical functioning, patients with complex CHD do worse than patients with moderate or mild defects or healthy individuals. APPROACH-IS was a large-scale international project that confirmed international variations in QoL, with Australian patients reporting the best QoL. Poor QoL was predicted by older age, being a job seeker, unemployed or disabled, never having married and those with worse functional status. Perceived illness and religion and spirituality were also significant predictors for QoL. On the other hand, country-specific characteristics and healthcare system factors did not play a significant role in explaining variances in QoL of patients with CHD around the globe. Future studies should rely on a sound conceptual basis, use longitudinal research designs, be conducted in international, multi-centre settings and evaluate interventions that promote patients' QoL.

Neutrophils and neutrophil-lymphocyte ratio: Inflammatory markers associated with intimal-media thickness of atherosclerosis

INTRODUCTION

Cardiac-cerebral vascular diseases (CCVDs) are global health problems due to the characteristic of high mortality. It is found that atherosclerosis (AS), a main cause of CCVDs, is significantly relevant to the change of intimal and media thickness. Neutrophil count (NEU) and neutrophil-lymphocyte ratio (N/L) are recognized possible risk factors for atherosclerosis (AS). However, there are few studies on the separate relationship between carotid intimal thickness, media thickness and NEU, N/L. This study explored the respective effects of NEU and N/L on AS and intimal, media thickness.

MATERIALS AND METHODS

The χ², Spearman's rho test, and multiple linear regression were implemented to analyze the relevance between blood parameters and intimal-media thickness. The potential factors, affecting non-depression time (NDT), is identified by univariate Cox regression. ROC curve was performed to determine the ability of blood parameters to predict intimal-media thickness. Immunohistochemistry was implemented.

RESULTS AND CONCLUSION

Based on χ², Spearman's rho test and multiple linear regression, NEU is related with intimal thickness (P < 0.05). Furthermore, NEU can predict the intimal thickness through the ROC curve. What's more, N/L is a risk factor of carotid media thickness (P < 0.05) by the Spearman's rho test, and is also correlated with poor NDT (P < 0.05) based on univariate Cox proportional regression analysis. Through ROC curve, N/L can predict the carotid media thickness. The carotid atherosclerotic endarterium is richest in macrophagocytes, and the arrangement of endotheliocytes is disordered. In summary, the increased NEU and N/L respectively have a strong correlation and precise predictability for carotid intimal and media thickness of atherosclerosis.
