Impact of congenital heart disease on clinical outcomes of oral propranolol therapy for Infantile hemangiomas: a propensity score-matched analysis.

Background: Oral propranolol is the first-line treatment for Infantile hemangioma (IH). However, there is a lack of studies indicating whether the congenital heart disease (CHD) makes a difference in oral propranolol therapy (OPT). Previous studies have only confirmed the safety and efficacy of OPT in asymptomatic CHD children.

Objective: This study aimed to evaluate and compare the clinical outcomes in pediatric patients with CHD and those without CHD following OPT and to assess risk factors that may contribute to recurrence.

Methods: A total of 310 children who received OPT for IH between January 2020 and January 2023 were included in a retrospective study. The study aimed to assess demographic data, clinical symptoms, auxiliary examinations, and treatment effects. To compare clinical outcomes between children with and without CHD, one-to-one propensity score matching (PSM) was applied.

Results: Among the 310 patients, 192 (61.94%) had CHD. After propensity-matching analysis, in the presence of CHD, the age at treatment withdrawal was significantly higher (15.0 months vs. 12.0 months, P < 0.05), the treatment duration was longer (12.0 months vs. 10.0 months, P < 0.05), and the recurrence rate was greater (32.9% vs. 5.3%, P < 0.001). No significant difference in the degree of regression was observed between the CHD and non-CHD groups.

Conclusion: Pediatric patients with CHD exhibit a later age at treatment withdrawal, a longer duration of therapy, and a higher recurrence rate compared to those without CHD.
