Background: Obesity and dyslipidemia afflict children of all ages. We explored the prevalence of obesity and dyslipidemia in pediatric heart transplant (HT) recipients and its effects on cardiac allograft vasculopathy (CAV) and survival.Methods: This study included primary HT recipients (≤18 years) transplanted between 01/1996 and 12/2018 included in the Pediatric Heart Transplant Society database. Obesity was categorized according to WHO/CDC guidelines and dyslipidemia according to the National Cholesterol Education Program. Kaplan-Meier analyses for CAV and graft loss stratified for BMI and lipid panels were generated and risk factors identified using multivariate analyses.Results: Among 6291 HT patients (median age [range] at HT = 4.3 [0.6-12.8] years; 45% Female; 68% White), 56% had a normal BMI at HT. Obese patients at HT had an increased risk for graft loss (
This scientific statement from the American Heart Association focuses on treatment strategies and modalities for cardiomyopathy (heart muscle disease) in children and serves as a companion scientific statement for the recent statement on the classification and diagnosis of cardiomyopathy in children. We propose that the foundation of treatment of pediatric cardiomyopathies is based on these principles applied as personalized therapy for children with cardiomyopathy: (1) identification of the specific cardiac pathophysiology; (2) determination of the root cause of the cardiomyopathy so that, if applicable, cause-specific treatment can occur (precision medicine); and (3) application of therapies based on the associated clinical milieu of the patient. These clinical milieus include patients at risk for developing cardiomyopathy (cardiomyopathy phenotype negative), asymptomatic patients with cardiomyopathy (phenotype positive), patients with symptomatic cardiomyopathy, and patients with end-stage cardiomyopathy. This scientific statement focuses primarily on the most frequent phenotypes, dilated and hypertrophic, that occur in children. Other less frequent cardiomyopathies, including left ventricular noncompaction, restrictive cardiomyopathy, and arrhythmogenic cardiomyopathy, are discussed in less detail. Suggestions are based on previous clinical and investigational experience, extrapolating therapies for cardiomyopathies in adults to children and noting the problems and challenges that have arisen in this experience. These likely underscore the increasingly apparent differences in pathogenesis and even pathophysiology in childhood cardiomyopathies compared with adult disease. These differences will likely affect the utility of some adult therapy strategies. Therefore, special emphasis has been placed on cause-specific therapies in children for prevention and attenuation of their cardiomyopathy in addition to symptomatic treatments. Current investigational strategies and treatments not in wide clinical practice, including future direction for investigational management strategies, trial designs, and collaborative networks, are also discussed because they have the potential to further refine and improve the health and outcomes of children with cardiomyopathy in the future.
Background Ideal “cardiovascular health” (CVH)–optimal diet, exercise, nonsmoking, BMI, BP, lipids, and glucose—is associated with healthy longevity in adults. Pediatric heart transplant (HT) patients may be at risk for suboptimal CVH. Methods Single-center retrospective study of HT patients 2003–2014 who survived 1 year post-transplant. Five CVH metrics were collected at listing, 1, 3 and 5 years post-transplant (diet and exercise were unavailable). CVH was scored by summing individual metrics: ideal = 2, intermediate = 1, and poor = 0 points; total scores of 8–10 points were considered high (favorable). CVH was compared between HT patients and the US pediatric population (GP) utilizing NHANES 2007–2016. Logistic regression was performed to examine the association of CVH 1 year post-transplant with a composite adverse outcome (death, re-listing, coronary vasculopathy, or chronic kidney disease) 3 years post-transplant. Results We included 110 HT patients (median age at HT: 6 years [range 0.1–21]) and 19,081 NHANES participants. CVH scores among HT patients were generally high at listing (75%), 1 (74%), 3 (87%) and 5 (76%) years post-transplant and similar to GP, but some metrics (e.g., glucose) were worse among HT patients. Among HT patients, CVH was poorer with older age and non-Caucasian race/ethnicity. Per 1-point higher CVH score, the demographic-adjusted OR for adverse outcomes was 0.95 (95% CI, 0.7–1.4). Conclusions HT patients had generally favorable CVH, but some metrics were unfavorable and CVH varied by age and race/ethnicity. No significant association was detected between CVH and adverse outcomes in this small sample, but study in a larger sample is warranted.

BackgroundSurvival after pediatric heart transplant (HT) has improved over time, with more than half of recipients now living at least 17 years after HT (1, 2). Two of the main factors limiting long-term survival among pediatric HT recipients are coronary allograft vasculopathy (CAV) (3) and chronic kidney disease (CKD) (1). Evidence-based preventive strategies are elusive, but observational data in pediatric and adult HT recipients suggest that traditional cardiovascular risk factors, such as dyslipidemia and obesity, are associated with increased risk for these complications (4-6). Previous studies have shown that pediatric HT recipients have elevated levels of total cholesterol (TC) and triglycerides and lower levels of high density lipoprotein (HDL-C) when compared to the general pediatric population (7-10). As dyslipidemia is associated with CAV development in adult HT recipients, a icted patients may be at increased cardiovascular risk (4,5,(11)(12)(13)(14). CKD, also known to increase mortality and morbidity in both adult and pediatric HT recipients, is also exacerbated by cardiovascular risk factors (15,16). Despite the continued trend of increased obesity seen in the general pediatric population, with 17% of children between the ages of 2-19 years classi ed as obese and 5.8% as morbidly obese (17), there have been limited data o...
Background: Adverse effects of clinician burnout have been studied across multiple specialties; however, there have been no studies examining rates of burnout among pediatric solid organ transplant teams. This study aimed to measure burnout, work exhaustion, professional fulfillment, and post-traumatic stress symptoms among clinicians and administrators practicing in this high-stress field. Methods:This cross-sectional study utilized a 50 item web-based survey that included the Personal Fulfillment Index and the IES-R. This survey was distributed across four pediatric solid organ transplant centers in North America. Basic demographics, clinician characteristics, and information regarding wellness and self-care activities were collected. Descriptive and correlational analyses were performed.Results: One hundred and thirty five participants completed the survey, 76% were female and 78% were Caucasian. One-third (34%) of participants endorsed burnout, while 43% reported professional fulfillment. Approximately 15% of respondents endorsed clinically significant levels of post-traumatic stress symptoms related to patient deaths, with female clinicians more likely to endorse symptoms (p = .01). Nearly 80% of participants reported engaging in self-care activities outside of work and only 10% of participants reported participation in hospital-sponsored wellness programs. Conclusions: Pediatric solid organ transplant team members exhibited moderate levels of burnout, professional fulfillment, and post-traumatic stress. Female clinicians were the most likely to experience both work exhaustion and post-traumatic stress symptoms. Transplant centers are encouraged to consider interventions and programming to improve clinician wellness.
