Long-term effect of critical illness after severe paediatric burn injury on cardiac function in adolescent survivors: an observational study. Lancet Child Adolesc Health 2017; 1: 293– 301; doi. https://doi.org/10.1016/S2352-4642(17)30122-0Google Scholar Investigators from multiple institutions conducted a prospective observational study to assess the long-term cardiac sequelae of adolescent survivors of severe pediatric burn injury. Participants were eligible if they had a history of severe burn affecting at least 30% of the total body surface area at least 5 years before the study period, were treated acutely for the burn at the study institution, and were receiving follow-up care at the study institution. A convenience sample of healthy controls was also enrolled as age-matched controls. All study participants had demographic and medical information collected at enrollment, and all underwent transthoracic echocardiography to measure ejection fraction, diastolic function, ventricular compliance, and myocardial fibrosis. Exercise testing was also performed to assess peak oxygen consumption (VO2). Symptoms of heart failure were assessed among burn participants using the New York Heart Association (NYHA) classification (class I: no symptoms or limitation, class II: mild symptoms, class III: marked limitation in activity due to symptoms, and class IV: severe limitations). Investigators compared the cardiac characteristics among burn participants and healthy controls. Data on 40 burn participants and 25 healthy controls were included in analysis. Compared to healthy controls, burn participants had significantly lower ejection fractions (52% vs 61%, P=.004), worse diastolic function, and more myocardial fibrosis. Burn participants also had significantly lower absolute VO2 during exercise testing compared to healthy controls. Overall, most burn participants were classified as NYHA class I (65%), with 33% class II, 3% class III, and none as class IV. The investigators conclude that adolescent survivors of severe burns have long-term reductions in ejection fraction, diastolic function, and exercise tolerance.

Significant burn injuries can lead to systemic responses affecting every organ system, including the heart and circulatory system. Acutely, cardiac stress secondary to increased catecholamine response is marked by tachycardia, increased myocardial oxygen consumption, and increased cardiac output. There are also elevated levels of catecholamines and stress hormones that persist for many years.1 Though the short-term activation of the stress response is important for survival, the prolonged duration leads to deleterious effects on metabolism, immune function, and cardiovascular function.2 Duke et al3 performed a population-based longitudinal study reviewing children with burn injuries and found that children with burns had 1.3 times as many admissions and 2.3 times the number of days in hospital for circulatory diseases. In a separate population-based longitudinal study, the same authors demonstrated that burn patients had increased hospital admission rates, prolonged length of hospital stay, and increased long-term mortality related to circulatory system diseases.1 The results of...
