Chest pain in pediatric patients is a common concern in pediatric emergency departments (ED). In most cases, benign conditions are related to noncardiac causes, and only a minority of the cases are caused by heart disease. This research aimed to evaluate the causes and characteristics of chest pain among children in a pediatric emergency department. This retrospective study evaluated children younger than 14 years of age who presented to the emergency department of a general pediatric hospital in the Eastern area of Saudi Arabia with non-traumatic chest pain between 2017 and 2022. The data included socioeconomic information, physical examination findings, and the results of basic investigations, such as chest X-ray and electrocardiogram. The Chi-square test was performed to compare various etiologies, with a 5% significant level. The study evaluated 310 patients with a mean age of 9.1±2.7 years. The majority of children presenting with chest pain had normal physical examinations, except 3.3% who showed respiratory and cardiac findings. The diagnostic tests indicated pneumonia in 2.9% and arrhythmia in 2.1% of children. Most patients were discharged with a diagnosis of idiopathic or muscular chest pain. The majority of patients (95%) were treated symptomatically in outpatient settings, with just one patient requiring hospitalization. The most common cause of chest pain prompting a child to visit the ED was idiopathic chest pain. Therefore, this study highlights the significance of obtaining a comprehensive medical history and physical examination to reveal important clues and help avoid unnecessary tests.
