The experience of being diagnosed with hypertrophic cardiomyopathy through family screening in childhood and adolescence

Use of Photovoice to Explore Pediatric Patients with Hypertrophic Cardiomyopathy and their Parents' Perceptions of a Heart-Healthy Lifestyle

Background

Heart‐healthy lifestyles promote lifelong cardiovascular health. However, patients with hypertrophic cardiomyopathy are often advised to avoid strenuous exercise because of the risk of sudden cardiac death. Given these restrictions, this study explored youth and parent perceptions of a heart‐healthy lifestyle and the barriers and facilitators to this lifestyle.

Methods and Results

Youth and parents were purposefully recruited at 2 Canadian hospitals for this photovoice project. Participants were given cameras and took pictures of everyday heart‐healthy or heart‐unhealthy choices. Photos were discussed during one‐on‐one qualitative interviews with youth and parents separately to understand the photos’ meaning and significance. Inductive descriptive thematic analysis was employed. A total of 16 youth (median age, 14.4 years [range, 10.5–17.7 years]; 63% boys) and 16 parents (100% women) participated. A total of 15 youth were activity restricted. Data analysis revealed 7 categories organized into perceptions of healthy living (health is holistic and individualized) and factors influencing engagement in healthy living (self‐awareness, ownership and autonomy, feeling restricted and peer pressure, support from parents, and support from the cardiologist). Participants had a complex understanding of health and discussed the importance of physical, mental, and social well‐being. Youth used self‐awareness and taking responsibility as facilitators of healthy living. Healthy living was shaped by peers, parent role‐modeling, and cardiologist recommendations.

Conclusions

This study depicts the realities for youth with hypertrophic cardiomyopathy and can be used to inform the development of responsive interventions. Holistic, patient‐specific interventions may be more successful, and strategies such as shared decision making may be important to promote self‐awareness and autonomy.

Living with hypertrophic cardiomyopathy: a patient's perspective

Hypertrophic cardiomyopathy (HCM) is a complex disease characterized by thickening of the cardiac muscle. Common symptoms include chest pain, shortness of breath, palpitations, fatigue and syncope (fainting), which are often confused for other conditions. Clinical treatment focuses on the relief of symptoms with medical therapies, which provide adequate to more variable symptomatic relief. Patients may experience more severe complications that require surgical intervention, such as implantable cardioverter-defibrillator therapy or septal myectomy. Despite the potential impact on quality of life, the humanistic burden of HCM is not well established. Here, we present four patient testimonials that highlight challenges faced by patients and clinicians in diagnosing HCM and managing symptoms. These testimonials provide valuable information on the spectrum and expression of HCM across generations. Such testimonials can better inform disease diagnosis and monitoring, maximizing quality of life and improving disease outcome.

The experience of hope in families of children and adolescents living with chronic illness: A thematic synthesis of qualitative studies

AIM

To synthesize qualitative studies on the experience of hope in families of children and adolescents living with chronic illness.

BACKGROUND

Hope is multidimensional, dynamic, and varies according to experienced events, cultural environments and stage of life. The qualitative synthesis of the experience of hope in the paediatric population with chronic conditions is scarce.

DESIGN

Thematic synthesis of qualitative studies.

DATA SOURCES

A systematic literature search in PubMed, CINAHL, LILACS, PsycINFO, Scopus, and Web of Science was performed supplemented by manual search strategies. Thirty-one studies from fifteen countries, published between 1981-2018, were included.

FINDINGS

Findings were integrated into an analytical theme "FAMILY HOPE: KEEPING THE DAY-TO-DAY BALANCE", encompassing the following five descriptive themes: Uncertainty; Support; Information; Between "dark thoughts" and positive thoughts; and Hoping to go back to normality.

CONCLUSION

This thematic synthesis brings a new dimension of hope among families of children and adolescents living with chronic illness. "Family Hope" highlights the influence of the relationships between relatives and the chronically ill child in the balance of hope. It is recommended that health professionals use a family-focused approach to support these families.

IMPACT

Shifting the focus to a family dimension of hope is a promising pursuit that has the potential to inform future nursing practices to support the experiences of families living with chronic illness in the paediatric context. A better understanding of the role and characteristics of family hope will promote the development of more effective interventions for families to adapt to long-term paediatric conditions.

Practice Variation among an International Group of Genetic Counselors on when to Offer Predictive Genetic Testing to Children at Risk of an Inherited Arrhythmia or Cardiomyopathy

Cascade predictive genetic testing is available for many families as a means to identify individuals at risk of long QT syndrome (LQTS), catecholaminergic polymorphic ventricular tachycardia (CPVT), hypertrophic cardiomyopathy (HCM), and arrhythmogenic right ventricular cardiomyopathy (ARVC). The general issue of offering predictive genetic testing to minors has been an area of ethical debate among genetic counselors and other healthcare professionals for many years. An online questionnaire was circulated to four international genetic counseling associations to assess the views of cardiac genetic counselors regarding when to offer predictive genetic testing to children at risk of LQTS, CPVT, HCM, and ARVC. Analysis was both quantitative and qualitative. The study sample comprised 98 respondents. The majority reported that they offer predictive genetic testing before 5 years of age to children at risk of LQTS (83%) and CVPT (75%) and before 10 years of age to children at risk of HCM (66%) or ARVC (70%). Influencing factors included country of practice, clinical setting, and years of experience. The rationale provided for when to offer predictive genetic testing is encompassed by the ethical principles of beneficence, non-maleficence, autonomy, and informed consent. In conclusion, significant practice variation exists among cardiac genetic counselors regarding predictive genetic testing for children at risk of an inherited cardiomyopathy. These variations call for more research in the area to assist with the development of evidence-based guidelines.

The mental health of adolescents and pre-adolescents living with inherited arrhythmia syndromes: a systematic review of the literature

Potentially fatal arrhythmias add to the mental health challenges of adolescence. This systematic review sought to summarise current knowledge regarding the mental health of adolescents and pre-adolescents diagnosed with inherited arrhythmia syndromes. Searches combining psychological problems with inherited cardiac arrhythmia diagnoses identified 16 studies with paediatric (<18 years) inherited arrhythmia patients. All studies were cross-sectional; 8/16 required an implantable cardioverter defibrillator. Methods were quantitative (n=11), qualitative (n=4), or mixed (n=1), with 14-100% of participants having an inherited arrhythmia syndrome. Mean/median age in 13/16 studies was 12-16 years. Patients and parents reported lower quality of life, particularly in relation to physical function, social relationships, restriction of peer activities, bodily pain, and mental and emotional health. Self-perceptions and behaviour were similar to healthy populations. Rates of anxiety and depression (15-33% of these patients) were not increased in these studies where patients were assessed 2+ years after diagnosis. Higher mental health risk occurred among patients who have a diagnosed sibling, those with cardiomyopathy, and those who report decreased quality of life. Mental health research among youth with inherited arrhythmias is extremely limited and of low quality. Data, primarily from patients 2-4 years after diagnosis or treatment with an implantable cardioverter defibrillator, indicate that quality of life may be decreased and 15-33% experience mental health issues. Future research is required to examine the mental health and quality of life of paediatric patients with inherited arrhythmia syndromes, whether or not they have an implantable cardioverter defibrillator, from time of diagnosis.

Children's experiences of congenital heart disease: a systematic review of qualitative studies

We aimed to describe the experiences of children and adolescents with congenital heart disease (CHD). Electronic databases were searched until August 2016. Qualitative studies of children's perspectives on CHD were included. Data was extracted using thematic synthesis. From 44 studies from 12 countries involving 995 children, we identified 6 themes: disrupting normality (denying the diagnosis, oscillating between sickness and health, destabilizing the family dynamic), powerlessness in deteriorating health (preoccupation with impending mortality, vulnerability to catastrophic complications, exhaustion from medical testing), enduring medical ordeals (traumatized by invasive procedures, disappointed by treatment failure, displaced by transition, valuing empathy and continuity in care, overcoming uncertainty with information), warring with the body (losing stamina, distressing inability to participate in sport, distorted body image, testing the limits), hampering potential and goals (feeling disabled, unfair judgment and exclusion, difficulties with academic achievement, limiting attainment and maintenance of life milestones), and establishing one's own pace (demarcating disease from life, determination to survive, taking limitations in their stride, embracing the positives, finding personal enrichment, relying on social or spiritual support).

CONCLUSION

Children with CHD feel vulnerable and burdened by debilitating physical symptoms, unpredictable complications, and discrimination. Clinicians may support patients by sharing recognition of these profound psychosocial consequences. What is Known: • CHD is associated with difficulties in learning and attention, school absenteeism, decreased endurance, poor body image, and peer socialization • What is lesser known is how young patients cope with the symptoms, prognostic uncertainty, and treatment burden What is New: • We found that children are challenged by lifestyle restrictions, fear of invasive procedures, impaired body image, discrimination, and uncertainty about the future. Feelings of disempowerment are intensified by the unpredictability of disease progression • Thus, strategies to improve outcomes include improved patient education on disease and lifestyle management and partnership with school teachers and counselors for unique psychosocial support.

Genetic association between 1425G/A SNP in PRKCH and hypertrophic cardiomyopathy in a Chinese population

Hypertrophic cardiomyopathy is a heterogeneous myocardial disorder with a broad spectrum of clinical presentation and morphologic features. Previous reports indicated that protein kinase C pathway as a major determinant of cardiac hypertrophy and heart failure. Population-based analyses of the association between PRKCH gene (encoded PKCη) and HCM has not been performed yet. The purpose of this study is to investigate the association of the nonsynonymous SNP (1425G/A) in PRKCH gene and hypertrophic cardiomyopathy in a Chinese population. 323 patients with HCM and 326 controls were examined using a case-control methodology. The 1425G/A SNP in PRKCH was genotyped by allele-specific real-time PCR assay. The 1425G/A SNP in PRKCH increased the risk of HOCM (hypertrophic obstructive cardiomyopathy) (OR=1.427, 95% confidence interval, 1.013 to 2.012, P=0.046) under a dominant model. After age- and sex-adjustment, the significant associations remained in HOCM (for GG +AG versus AA, OR= 2.497, 95% confidence interval, 1.01 to 6.17; P=0.047). The 1425G/A SNP in PRKCH increases the risk of hypertrophic obstructive cardiomyopathy in the Chinese population.

The under reporting of recruitment strategies in research with children with life-threatening illnesses: A systematic review

BACKGROUND

Researchers report difficulties in conducting research with children and young people with life-limiting conditions or life-threatening illnesses and their families. Recruitment is challenged by barriers including ethical, logistical and clinical considerations.

AIM

To explore how children and young people (aged 0-25 years) with life-limiting conditions or life-threatening illnesses and their families were identified, invited and consented to research published in the last 5 years.

DESIGN

Systematic review.

DATA SOURCES

MEDLINE, PsycINFO, Web of Science, Sciences Citation Index and SCOPUS were searched for original English language research published between 2009 and 2014, recruiting children and young people with life-limiting conditions or life-threatening illness and their families.

RESULTS

A total of 215 studies - 152 qualitative, 54 quantitative and 9 mixed methods - were included. Limited recruitment information but a range of strategies and difficulties were provided. The proportion of eligible participants from those screened could not be calculated in 80% of studies. Recruitment rates could not be calculated in 77%. A total of 31% of studies recruited less than 50% of eligible participants. Reasons given for non-invitation included missing clinical or contact data, or clinician judgements of participant unsuitability. Reasons for non-participation included lack of interest and participants' perceptions of potential burdens.

CONCLUSION

All stages of recruitment were under reported. Transparency in reporting of participant identification, invitation and consent is needed to enable researchers to understand research implications, bias risk and to whom results apply. Research is needed to explore why consenting participants decide to take part or not and their experiences of research recruitment.

Psychosocial adjustment and quality of life in children undergoing screening in a specialist paediatric hypertrophic cardiomyopathy clinic

OBJECTIVE

This study aimed to assess the psychological well-being and quality of life in children with hypertrophic cardiomyopathy and the potential psychosocial impact of screening.

METHODS

A total of 152 children (aged 3-18 years) attending a specialist paediatric hypertrophic cardiomyopathy clinic, and their parents completed the Generic Core Scales and Cardiac Module of the Paediatric Quality of Life Inventory (PedsQL) questionnaire as well as the Strengths and Difficulties Questionnaire; 21 patients (14%) had hypertrophic cardiomyopathy (group A); 23 children (15%) harboured hypertrophic cardiomyopathy-causing sarcomeric mutations with normal echocardiograms (group G); and 108 children (71%) had a family history of hypertrophic cardiomyopathy with normal investigations and attended for clinical cardiological screening (group S).

RESULTS

In group A, mean PedsQLTM total scores reported by children and parents were lower than those reported by unaffected children (p<0.001). There was no significant difference between unaffected and gene-positive patients. Mean Cardiac module PedsQLTM total scores by children and parents were lower in children with hypertrophic cardiomyopathy compared with unaffected patients [mean child-reported total score 86.4 in group S versus 72.3 in group A (p<0.001) and 80.2 in group G (p=0.25); mean parent-reported total score 91.6 in group S versus 71.4 in group A (p<0.001) and 87 in group G (p=0.4)]. There was no significant difference between group S and group G on any of the scales, or between the three groups of patients in the mean Strengths and Difficulties Questionnaire scores.

CONCLUSIONS

Children with hypertrophic cardiomyopathy have a significantly reduced quality of life. Importantly, Quality-of-Life scores among unaffected children attending for screening were not different compared with scores from a normative UK population.
