What Are the Most Common Causes of Chest Pain in Children?

Chest pain in a child can be concerning, especially when the discomfort is described as chest pain near the heart. However, chest pain in children is usually not caused by heart disease. Pediatric guidance consistently shows that chest-wall and other non-cardiac causes are far more common, while cardiac causes account for only a small proportion of cases.

The key is to understand how the pain starts, where it occurs, what triggers it, and whether it comes with symptoms such as fainting, breathing difficulty, fever, palpitations, or reduced exercise tolerance. These details help doctors understand what can cause chest pain and whether further evaluation is needed.

Is Chest Pain in Children Usually Related to the Heart?

Unlike adults, children rarely develop chest pain because of coronary artery disease. The muscles and bones of the chest wall, lungs, airways, digestive system, and other non-cardiac sources are much more frequent causes of discomfort. Recent pediatric studies continue to find that heart-related disease accounts for only a minority of children evaluated for chest pain.

Still, uncommon does not mean impossible. A child with concerning symptoms, known heart disease, an abnormal examination, or a significant family history may need assessment by a pediatric cardiologist.

Chest Wall and Musculoskeletal Pain

Chest-wall or musculoskeletal pain is one of the most common causes of chest pain in children and teenagers. It may develop after sports, vigorous physical activity, repeated coughing, carrying a heavy backpack, or a minor injury. Pain may become stronger when the child moves, twists, takes a deep breath, or when a particular area of the chest is pressed.

Costochondritis is another musculoskeletal cause. It involves irritation or inflammation where the ribs connect to the breastbone and may cause sharp, aching, or tender pain in the front of the chest.

Some children experience precordial catch syndrome. It typically causes sudden, sharp pain in a small area of the chest, often on the left side. The discomfort can become worse when taking a deep breath but usually lasts only a short time and settles on its own. Despite occurring close to the heart, it is generally a benign chest-wall pain rather than heart disease.

Respiratory and Lung-Related Causes

The lungs and airways can also produce chest discomfort. A child who has been coughing repeatedly during a cold may develop soreness in the muscles between the ribs or across the chest.

Asthma may cause tight chest pain, chest tightness, coughing, wheezing, or shortness of breath. These symptoms may become more noticeable during exercise or following exposure to an asthma trigger.

Respiratory infections such as pneumonia can also cause chest pain, particularly while coughing or taking a deep breath. Fever, cough, fast or difficult breathing, tiredness, and reduced appetite may occur alongside the pain.

Chest pain accompanied by severe difficulty breathing or blue or gray discoloration around the lips requires urgent medical attention.

Acid Reflux and Digestive Causes

Not every pain felt in the chest begins in the heart or lungs. Gastroesophageal reflux can produce burning discomfort behind the breastbone, sometimes described by children as chest pain, burning, or even “heart pain.” Reflux is a recognized non-cardiac cause of pediatric chest discomfort.

Symptoms may be related to meals or lying down. Depending on the child, there may also be burping, nausea, a sour taste, or upper abdominal discomfort.

Because different conditions can feel similar, parents should not try to identify heart pain reasons from location alone. The pattern of symptoms and a clinical examination are more useful.

Stress, Anxiety, and Changes in Breathing

Stress and anxiety can produce genuine physical symptoms in children. Chest tightness may occur alongside rapid breathing, a racing heartbeat, dizziness, or a sensation that it is difficult to take a satisfying breath. Psychogenic or stress-related causes are recognized among the non-cardiac causes of pediatric chest pain.

However, recurring chest pain should not automatically be labelled as anxiety. Other relevant causes should first be considered, particularly when symptoms occur during physical activity or are associated with fainting, significant breathing difficulty, or palpitations.

Cardiac Causes: Uncommon but Important

Although heart-related chest pain is uncommon in children, several cardiac conditions can cause it. These include myocarditis, which is inflammation of the heart muscle; pericarditis, which involves inflammation around the heart; certain abnormal heart rhythms; cardiomyopathy; and some congenital or structural heart conditions.

The pattern of pain is particularly important. Chest pain that repeatedly occurs during exercise deserves more attention than brief, sharp discomfort occurring at rest. Pain accompanied by fainting, near-fainting, significant palpitations, or unusual shortness of breath should also be medically evaluated.

Family history matters as well. Cardiomyopathy, inherited heart rhythm disorders, or unexplained sudden death at a young age in close relatives may increase concern and should be discussed with the child's doctor.

When Does Chest Pain Need Urgent Medical Attention?

Parents should arrange prompt or emergency medical assessment when chest pain:

• occurs repeatedly during exercise or becomes severe and persistent;

• is accompanied by fainting, collapse, or severe dizziness;

• occurs with significant breathing difficulty or blue/gray lips;

• is associated with a very fast or irregular heartbeat;

• occurs in a child with known heart disease or a concerning family history; or

• appears with fever, worsening breathing symptoms, or a child who looks seriously unwell.

  
  

Exertional chest pain and exertional fainting are among the important warning features used when deciding whether specialist cardiology evaluation is appropriate.

If a child develops severe chest pain together with serious breathing difficulty, collapse, or loss of consciousness, emergency medical care should be sought rather than waiting for a routine appointment.

How Do Doctors Evaluate Chest Pain in Children?

Evaluation usually starts with a detailed history and physical examination. The doctor may ask when the pain occurs, whether exercise triggers it, whether pressing on the chest reproduces the pain, and whether the child has cough, fever, wheezing, digestive symptoms, dizziness, palpitations, or fainting.

Not every child with chest pain requires extensive testing. Pediatric guidelines recommend using the clinical history, examination, and risk factors to decide whether investigations are necessary. Tests may include an electrocardiogram (ECG), chest imaging, blood tests, echocardiography, or other investigations when clinically indicated.

A pediatric cardiac consultation may be appropriate when the symptoms, examination findings, medical history, or family history raise concern for a cardiac cause.

The Bottom Line

Most chest pain in children comes from conditions outside the heart. Muscle strain, chest-wall irritation, costochondritis, precordial catch syndrome, asthma, respiratory infections, reflux, and stress-related symptoms are considerably more common than serious cardiac disease.

At the same time, parents should pay attention to when the pain occurs and what happens with it. Chest pain during exercise, fainting, significant palpitations, unusual breathing difficulty, known heart disease, or a concerning family history deserves medical evaluation rather than being ignored.

cardiomyopathy, pediatric arrhythmias, and other childhood heart conditions. When a child's symptoms suggest that the heart requires closer assessment, a pediatric cardiac consultation can help determine whether an ECG, echocardiogram, further testing, or follow-up is appropriate.

Frequently Asked Questions

Can exercise cause chest pain in children?

Yes. Exercise may cause muscle strain or breathing-related discomfort, but recurring chest pain during exercise should be evaluated by a healthcare professional.

Should a child stop sports because of chest pain?

A child should stop strenuous activity until evaluated if chest pain occurs during exercise, especially with dizziness, fainting, palpitations, or breathing difficulty.

Why does my child complain of chest pain at night?

Night-time chest pain may be linked to reflux, respiratory symptoms, muscle discomfort, or anxiety. Persistent or recurring pain requires medical evaluation.

Can chest pain be a sign of an abnormal heart rhythm?

Sometimes, but rhythm problems more commonly cause palpitations, dizziness, or fainting. Chest pain with these symptoms should receive prompt medical assessment.
