Overview

Chest pain is the second cardiac symptom after cardiac murmur that is referred to a pediatric cardiologist for evaluation. the most common cause of chest pain in children is idiopathic without finding any specifice underlying problem and the second cause is musculoskeletal. Although there are high worries among parents about the cardiac origin of chest pain in children, it consists in low percentage the causes of chest pain. Evaluation of chest pain includes assessments of the respiratory system, gastrointestinal system, cardiac diseases and psychologic factors.

Causes

Life Threatening Causes

Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.

• Cardiac causes such as life-threatening arrhythmia, acute coronary syndrome, acute pulmonary embolism, tamponade

• Perforated peptic ulcer
• Air leak syndrome such as Pneumothorax, pneumomediastinum

Common Causes

• Ideopathic

Do's

• Quickly evaluate cardiac examination in children presented with chest pain and syncope.

• Arrhythmia leading chest pain in children include: paroxysmal supraventricular tachycardia (PSVT), premature ventricular contraction (PVC), atrial flutter, mobitz type2 block ,atrial tachycardia, atrial premature contraction.
• Asthma is the most common cause of chest pain in the pulmonary group presenting with exertional chest pain.
• Think about pneumothorax among young adult male presented with tachypnea, persistent pleuritic chest pain for 1-2 days and take a chest-X-ray for evaluation of air leak syndrome.
• If the CXR is undiagnostic for evaluation of pneumomediastinum, chest CT-scan is considered.
• In patients with chest pain and hypoxia, pulmonary embolism should be noticed.

• Acute chest syndrome or pulmonary infarction can be the manifestation of sickle cell disease among children.
• In patients presented with GERD or gastritis, chest pain is described as burning pain in epigastric area related to taking food.
• Hyperventilation in patients with panic disorder or anxiety disorder may lead to chest pain, paresthesia, dizziness, shortness of breath.
• Chest pain may be initial presentation of deformities in chest wall such as scoliosis due to nerve root compression.
• Mitral valve prolapse may be present with atypical chest pain in children.
• In case of marfan disease with sudden onset severe chest pain with radiation to the back, dissection aorta aneurysm should be evaluated.
• In patients with history of arterial switch in transposition of the great arteries (d-TGA), ostial coronary artery stenosis should be noticed.

• Homozygous familial hypercholesterolemia may lead to coronary artery disease and ischemic chest pain in the first two decades in children.

Don'ts

• Do not hesitate for urgent evaluation of patients presented with chest pain accompanied by dyspnea or unstable hemodynamic.
