Insights Into Pediatric Pulmonary Hypertension: A Real-World Registry of Epidemiology and Outcomes

Pediatric pulmonary hypertension (PH) shares similarities with PH in adulthood, but specific differences still require unique approaches. Despite major advances, risk scores for pediatric PH still need to be validated, and targeted drug therapies in pediatric populations remain under-studied. Consequently, there is a great need for comprehensive real-world longitudinal data of pediatric PH. The INSPIRE-PH registry is a multicenter, observational, real-world registry designed to systematically collect longitudinal clinical data on children and adolescents with PH. Patients enrolled in the registry receive standard clinical care determined by their treating physicians. No study-mandated interventions are imposed. Longitudinal observation of this cohort aims to provide important insights into disease progression, treatment effectiveness, and long-term prognosis in pediatric PH. The cohort was initially established prospectively in 2006, with all cases reclassified according to the 7th World Symposium for Pulmonary Hypertension (WSPH) criteria in 2024, and new patients continue to be prospectively enrolled. The registry is supervised by the principal investigator, independently from the financial sponsors.
