Chest pain presenting during childhood is a common cause of admission to the emergency departments or to pediatric outpatient consultations. In most cases chest pain is idiopathic or secondary to musculoskeletal disorders, whereas a cardiac origin is confirmed in a minority (0.5-1%). The peak of incidence can be registered between 10-14 years, mainly involving males. Early identification of chest pain requiring further investigation allows a prompt diagnosis, limiting unnecessary exams and prolonged hospitalization.
