Although chest pain does not indicate serious disease of the heart or other systems in most pediatric patients, in a society with a high prevalence of atherosclerotic heart disease, it can be alarming to the child and parents. Physicians should be aware of the differential diagnosis of chest pain in children and should make every effort to find a specific cause before making a referral to a specialist or reassuring the child and the parents of the benign nature of the complaint.
Cardiac causes of chest pain are found in less than 5% of children with complaint of chest pain. Noncardiac causes of chest pain are found in 56% to 86% of reported cases.
Among 3700 patients who presented to a large children’s hospital with a complaint of chest pain, cardiac pathology or arrhythmias was found in only 1% of these patients, of whom 38% had SVT and 27% had pericarditis (Saleeb et al., 2011).
Table 20.1 lists the frequency of the causes of chest pain in children according to organ systems based on published data from six pediatric emergency departments and four pediatric cardiology clinics. According to the table, the three most common causes of chest pain in children are (a) costochondritis, (b) chest wall trauma or muscle strain, and (c) respiratory diseases, especially those associated with coughing.
Causes | Pediatric Emergency Department or Pediatric Clinic (Data from 6 Reports) (%) | Cardiology Clinic (Data from 4 Reports) (%) |
---|---|---|
Idiopathic/cause unknown | 12-61 | 37-54 |
Musculoskeletal/costochondritis | 7-69 | 1-89 |
Respiratory/asthma | 13-24 | 1-12 |
Gastrointestinal/gastroesophageal reflux disease | 3-7 | 3-12 |
Psychogenic | 5-9 | 4-19 |
Cardiac | 2-5 | 3-7 |
Gastrointestinal and psychogenic causes are identified in fewer than 10% of cases.
Even after a moderately extensive investigation, no cause can be found in up to 50% of patients (idiopathic chest pain).
In children with chronic chest pain, a cardiac cause is less likely to be found.
Box 20.1 is a partial list of possible causes of noncardiac and cardiac chest pain in children.
