Chest Pain in Children
& Adolescents
One of the most anxiety-inducing symptoms for any parent â yet in children, chest pain is rarely a heart problem. Here’s what the evidence actually says, and when to be concerned.
The Most Important Thing to Know
In adults, chest pain often signals a heart attack. In children, it almost never does. Childhood chest pain is overwhelmingly caused by muscles, bones, the digestive system, or anxiety â not the heart. That said, a careful evaluation is always worthwhile to rule out the rare but serious cardiac causes.
What Causes Chest Pain in Children?
Moss & Adams (10th Edition) describes chest pain as one of the most common reasons children are referred to a pediatric cardiologist â yet cardiac disease accounts for a small minority of cases. The distribution of causes is well-established:
Causes of Chest Pain in Children â Distribution
| Musculoskeletal / Idiopathic ~60% |
Gastrointestinal ~15% |
Respiratory ~10% |
Cardiac <5% |
|---|---|---|---|
| Costochondritis Muscle strain Tietze syndrome Trauma |
GERD Esophagitis Esophageal spasm |
Asthma Pleuritis Pneumonia |
Arrhythmias Pericarditis Structural CHD Myocarditis â ïļ Never miss! |
Chest pain in children is rarely cardiac. The most common cause is musculoskeletal. However, cardiac causes â though uncommon â must always be excluded.
The Non-Cardiac Causes (95%+ of Cases)
ðĶī Musculoskeletal
The single most common cause. Costochondritis â inflammation of the cartilage between ribs and breastbone â is classic. The key finding is point tenderness when you press on the chest wall. Pain worsens with movement and deep breathing.
Reassuring sign: If pressing on the chest reproduces the pain exactly, it’s almost certainly musculoskeletal.
ð―ïļ Gastrointestinal
Gastro-esophageal reflux disease (GERD) and esophagitis are common in children and cause burning chest pain, often after meals or when lying down. Esophageal spasm can cause severe, sudden chest pain that mimics cardiac pain.
Clue: pain relieved by antacids, associated with sour taste or regurgitation.
ðŦ Respiratory
Asthma can cause chest tightness mistaken for chest pain. Pleuritis causes sharp, positional pain worse with breathing. A pneumothorax (collapsed lung) causes sudden severe chest pain â an emergency especially in tall, thin adolescent boys.
ð§ Psychogenic / Anxiety
Panic attacks and anxiety are a significant cause, particularly in adolescents. They cause real chest pain accompanied by palpitations, shortness of breath, dizziness, and tingling. Associated with school, social, or family stressors.
Psychogenic chest pain is a diagnosis of exclusion â cardiac causes must first be ruled out.
Red Flags â When to Worry About the Heart
While cardiac causes are rare, they can be life-threatening. Moss & Adams specifically highlights the following red flags that should prompt urgent cardiac evaluation:
Red Flag Symptoms â Seek Immediate Evaluation
| âĪïļ CARDIAC RED FLAGS | |
|---|---|
| ⥠Pain with Exercise Chest pain triggered by or during exertion |
ðĩ Syncope / Fainting Loss of consciousness with or after chest pain |
| ðĻâðĐâð§ Family History Sudden cardiac death <50 yrs in close relative |
ð Palpitations + Chest Pain Concurrent arrhythmia symptoms |
| ðĄïļ Fever + Chest Pain Possible myocarditis or pericarditis |
ðĨ Known Heart Disease Any history of CHD or prior cardiac surgery |
Any red flag symptom with chest pain requires urgent ECG and cardiology referral. Exertional chest pain with syncope is a cardiac emergency until proven otherwise.
Cardiac Causes of Chest Pain â What Are We Looking For?
Hypertrophic Cardiomyopathy (HCM)
One of the most important cardiac causes to identify â and the leading cause of sudden cardiac death in young athletes. HCM causes exertional chest pain due to reduced blood flow to the thickened heart muscle. There is often a family history of unexplained cardiac death or HCM. Stress perfusion MRI and echocardiography are key diagnostic tools (Moss & Adams, Chapter 52).
Key Concern
HCM can cause sudden cardiac death during sports or exercise in otherwise healthy-appearing teenagers. Pre-participation screening is essential.
Anomalous Aortic Origin of a Coronary Artery (AAOCA)
A congenital abnormality where a coronary artery originates from the wrong part of the aorta. During exercise, this abnormal course can cause the artery to be compressed, leading to exertional chest pain, syncope, or sudden death. According to Moss & Adams (Chapter on coronary anomalies, pp. 1939â1940), this condition is rare but typically presents in early adolescence. There is no standard pre-symptomatic screening test, making presentation with symptoms the usual way it’s detected.
Myocarditis (Heart Muscle Inflammation)
Inflammation of the heart muscle, most commonly caused by viruses (especially Parvovirus B19, Coxsackie B, COVID-19). Myocarditis can present very similarly to a heart attack â chest pain, elevated troponin, and ECG changes. It most commonly affects adolescent males. Moss & Adams (pp. 3148â3149) notes that myocarditis must be considered in any young person presenting with ACS-like chest pain, especially after a recent viral illness.
Pericarditis (Heart Lining Inflammation)
Inflammation of the pericardium (the sac around the heart). The chest pain of pericarditis is sharp or stabbing, and classically:
- Worse when lying flat (supine)
- Better when sitting forward or leaning forward
- Worsens with deep breathing or coughing
The pathognomonic sign is a pericardial friction rub â a scratching sound heard with a stethoscope. Treatment is NSAIDs Âą colchicine. A rare form, post-pericardiotomy syndrome, occurs around the 10th day after cardiac surgery (Moss & Adams, Ch. 61).
Arrhythmias
Rapid heart rhythms (SVT, VT) can cause chest tightness or pain along with palpitations. Wolff-Parkinson-White (WPW) syndrome â a congenital electrical short-circuit â is an important cause. An ECG during or immediately after symptoms is crucial.
How Doctors Evaluate Chest Pain in Children
Evaluation Pathway for Chest Pain in Children
| Step 1: Detailed History Location, quality, timing, triggers, duration, red flags |
||
| âž | ||
| Step 2: Physical Exam Chest wall tenderness, auscultation, vitals |
||
| âž | ||
| Step 3: ECG (Always) 12-lead ECG â rapid, cheap, essential |

A structured evaluation prevents both missing serious cardiac causes and over-investigating benign musculoskeletal chest pain.
Cardiac Causes at a Glance
| Condition | Key Features | Key Test | Urgency |
|---|---|---|---|
| Hypertrophic Cardiomyopathy (HCM) | Exertional chest pain, family history of SCD, systolic murmur that changes with position | Echocardiogram, cardiac MRI | High |
| Anomalous Coronary (AAOCA) | Exertional chest pain/syncope in adolescent, no murmur, normal rest ECG | CT coronary angiography | High |
| Myocarditis | Recent viral illness, troponin elevated, ST changes, more in adolescent males | Troponin, echo, cardiac MRI | High |
| Pericarditis | Sharp pain worse lying flat, better leaning forward, pericardial rub on auscultation | ECG, CRP, echo | Moderate |
| Arrhythmia (SVT/WPW) | Palpitations + chest pain, sudden onset, young child or teenager | 12-lead ECG, Holter monitor | Moderate |
| Kawasaki disease (coronary aneurysm) | History of Kawasaki disease in infancy, exertional symptoms later in childhood | Echo, coronary angiography | High |
| Costochondritis (NOT cardiac) | Point tenderness on pressing chest wall, reproducible pain, no exertional component | Clinical diagnosis | Low â Reassure |
Go to Emergency Immediately If Your Child Has:
- Severe chest pain with difficulty breathing
- Chest pain + loss of consciousness or near-fainting
- Chest pain + lips or face turning blue (cyanosis)
- Chest pain that started during vigorous exercise and is now not resolving
- Known congenital heart disease + new chest pain
Frequently Asked Questions
ðŊ Key Takeaways for Parents
Chest pain in children is very rarely from the heart â over 90% of cases have a benign, non-cardiac cause.
The most common causes are musculoskeletal (costochondritis), gastrointestinal (reflux), and anxiety/psychogenic.
Red flags requiring urgent evaluation: chest pain with exercise, fainting, palpitations, family history of sudden cardiac death, or abnormal ECG.
An ECG is a quick, painless, essential first test for any child with chest pain and should be obtained in the initial evaluation.
Cardiac causes (HCM, anomalous coronaries, myocarditis, pericarditis) are rare but serious â they can be identified and managed with proper evaluation.
If your child’s cardiologist says the heart is normal â trust that evaluation. Reassurance is itself powerful medicine.
