Abstract:
Objective:To summarize and analyze the clinical characteristics of pediatric pulmonary hypertension (PH) and the related factors affecting the prognosis，to provide a basis for the early diagnosis and treatment of the disease.Methods:The clinical data of 80 PH children hospitalized in the intensive care department of Children's Hospital of Capital Pediatric Research Institute from January 1,2019 to December 31,2022 were retrospectively analyzed,and general data,clinical symptoms, echocardiography, laboratory examination and treatment indicators were collected. According to survival death groups, multivariate Logistic regression was applied to analyze independent associated risk factors for PH death.Results:（1）Clinical characteristics of childhood PH: more common in infants, the average age of treatment was 0.9(0.3-5.3)years, the male to female ratio was 1.3∶1, and the average time from first symptoms to first diagnosis was 6.5 (2,14) days. The etiology of PH in children was complex, with arterial PH (PAH) (40%), pulmonary disease and(or) hypoxia (33.8%) being the most common. The main clinical manifestations were dyspnea, decreased activity endurance, poor appetite, and positive heart examination. Severe PH accounted for 53.8%, 30% of pulmonary hypertensive crisis.（2）Factors affecting the prognosis of childhood PH: childhood PH mortality was 20.8%, compared with the survival group, ICU length of stay, loss of appetite, decreased urine volume, cardiac function classification, right heart size, main pulmonary artery diameter/ascending aorta diameter ratio(MPAD/MAD), vasoactive inotropic score(VIS), use of invasive ventilator treatment had statistical significance (all P<0.05). A Logistic regression analysis of death-related factors showed that right heart enlargement ( OR=0.193,95% CI 0.040-0.919, P=0.039), higher MPAD/MAD value ( OR =11.883,95% CI 1.347-104.869, P=0.026), and higher VIS score ( OR= 1.029,95% CI 1.003-1.056, P=0.028) were independent risk factors for poor prognosis. Conclusion:（1）Children PH is mainly infants, the causes of PAH and pulmonary diseases, severe PH accounted for 53.8%, 30% of which have pulmonary hypertensive crisis.（2）An enlarged right heart, higher MPAD/MAD values, and higher VIS score are independent risk factors for death in children with PH.
