0780 Prevalence of Pulmonary Hypertension in Pediatric Patients with Obstructive Sleep Apnea

Abstract Introduction Obstructive sleep apnea (OSA) is relatively common in pediatric patients and pulmonary hypertension (PHTN) has been previously reported as a complication of this disease. However, the true prevalence of PHTN in pediatric patients with OSA remains unknown. The purpose of this study is to determine the prevalence of PHTN in children with OSA and develop a clinical algorithm to help determine the need for pediatric cardiology evaluation in a pediatric patient with OSA. Methods Retrospective chart review of 259 pediatric patients in the military health system, aged 18 years and younger, with a diagnosis of OSA and a referral to pediatric cardiology. Chart reviews determined which patients were diagnosed with PHTN by a cardiologist. Comparisons between groups included gender and age characteristics as well as OSA severity levels and any co-morbid conditions. Results The percentage of military pediatric patients with OSA and referral to pediatric cardiology was 14.6% with 57.4% male. The AHI severity levels included 48.5% mild, 22.7% moderate, and 28.8% severe. A diagnosis of PHTN was found in 3.7% of the patients with OSA. Co-morbid, cardiac disorders were present in 100% of those with PHTN. Conclusion PHTN is a serious medical condition that may lead to significant morbidity and mortality. OSA is a common medical condition that has been associated with PHTN. The results of this study suggest that the prevalence of PHTN in pediatric patients with OSA is low and typically associated with co-morbid, cardiac conditions. Identifying at-risk patients for cardiac evaluation can improve their prognosis. Additionally, an evaluation algorithm can improve the medical decision making to determine which pediatric patients with OSA should have a cardiology evaluation. Support (If Any):
