Yes, teenagers can have a heart attack, but it is extremely rare. Heart attacks are much more common in older adults, where coronary artery disease caused by plaque buildup is usually responsible. In teenagers, a heart attack is more likely to be associated with an underlying heart or blood-vessel condition, rather than the typical plaque buildup seen in adults.

If a teenager develops chest pain during exercise, faints during physical activity, has unexplained difficulty breathing, or experiences severe or persistent chest pressure, the symptoms should not be ignored. Some heart conditions can become serious quickly and require immediate medical evaluation.

How Common Are Heart Attacks in Teenagers?

Heart attacks in teenagers are very uncommon. Cleveland Clinic notes that heart attacks are extremely rare among people ages 15 to 24. When they do occur, doctors generally look for an underlying genetic, congenital, inflammatory, or acquired condition affecting the heart or coronary arteries.

This is important because teenage chest pain does not automatically mean a heart attack. Most chest pain in children and teenagers is not caused by a heart problem. Muscle strain, coughing, acid reflux, asthma, and anxiety are among the more common causes.

What Can Cause a Heart Attack in a Teenager?

Although rare, several conditions can increase the risk of serious heart problems in teenagers.

1. Congenital Heart Conditions

Some teenagers are born with structural differences in the heart or coronary arteries. An abnormal coronary artery may affect blood flow to the heart muscle, particularly during physical activity.

Congenital heart disease can involve the heart chambers, valves, muscle, or blood vessels. Some conditions are diagnosed during childhood, while others may not become apparent until later.

2. Genetic Heart Conditions

Certain inherited conditions can affect the heart muscle, heart rhythm, or cholesterol levels.

For example, hypertrophic cardiomyopathy causes the heart muscle to become abnormally thick and can increase the risk of serious cardiac events in young people. Inherited cholesterol disorders can also increase the risk of early coronary artery disease.

3. Myocarditis

Myocarditis is inflammation of the heart muscle. It can occur after an infection and, in some cases, can affect the heart’s ability to pump blood or cause abnormal heart rhythms.

Myocarditis can sometimes cause symptoms that resemble a heart attack, including unexplained chest pain and shortness of breath.

4. Kawasaki Disease

Kawasaki disease is an inflammatory condition that primarily affects young children but can have long-term effects on the coronary arteries.

When coronary arteries are damaged, enlarged, or narrowed following Kawasaki disease, blood flow to the heart can be affected and increase the risk of serious cardiac complications.

5. Extremely High Cholesterol

Most teenagers do not have enough plaque buildup to cause a conventional heart attack. However, rare inherited cholesterol disorders can cause extremely high cholesterol levels from an early age.

One particularly severe inherited condition, homozygous familial hypercholesterolemia, can cause coronary artery disease during childhood or adolescence.

6. Certain Drugs and Lifestyle Factors

Some substances, including cocaine and other stimulants, can cause serious cardiovascular complications.

Smoking, physical inactivity, obesity, high blood pressure, diabetes, and unhealthy dietary patterns can also increase cardiovascular risk over time.

What Does a Heart Attack Feel Like in a Teenager?

The symptoms of a heart attack or another serious heart condition can vary. Concerning symptoms may include:

  • Chest pressure, tightness, or pain, particularly during exercise
  • Shortness of breath that is unusual for the level of activity
  • Fainting or nearly fainting during physical activity
  • Unexplained racing or irregular heartbeat
  • Severe weakness or dizziness
  • Pain or discomfort that does not go away

Chest pain accompanied by fainting, significant breathing difficulty, or other concerning symptoms requires prompt medical attention.

Important: A teenager does not need to have every symptom for a serious heart problem to be possible.

Is Chest Pain in Teenagers Usually a Heart Attack?

No. Chest pain in teenagers is usually caused by something other than the heart.

Common causes include:

  • Muscle strain or chest-wall pain
  • Costochondritis
  • Coughing or respiratory infections
  • Asthma
  • Acid reflux or heartburn
  • Anxiety or stress

The American Academy of Pediatrics notes that chest pain in children is rarely caused by the heart. However, chest pain that occurs during exercise, does not go away, or is associated with fainting should be evaluated by a healthcare professional.

When Should a Teenager With Chest Pain Go to the ER?

Seek emergency medical attention if a teenager has severe or persistent chest pain, significant trouble breathing, faints, becomes confused, develops blue or gray lips/face, or appears seriously ill.

In the United States, call 911 for a potentially life-threatening emergency rather than driving the teenager to the hospital yourself.

If chest pain repeatedly happens during running, sports, or other physical activity—even if it goes away after stopping—make an appointment with a healthcare professional for evaluation.

What Tests Can Doctors Use to Check a Teenager’s Heart?

Depending on the symptoms and medical history, a healthcare professional may perform a physical examination and consider tests such as:

  • Electrocardiogram (EKG/ECG)
  • Echocardiogram
  • Blood tests
  • Chest X-ray
  • Cardiac MRI
  • Holter or other heart-rhythm monitoring
  • Exercise testing

The appropriate tests depend on the teenager’s symptoms, family history, medical history, and examination findings.

Can Teenagers Prevent Heart Problems?

Not every cause of serious heart disease can be prevented. Some conditions are inherited or present from birth.

However, teenagers can support long-term heart health by:

  • Staying physically active
  • Eating a balanced diet
  • Avoiding smoking and recreational drugs
  • Maintaining a healthy weight
  • Attending recommended medical checkups
  • Knowing their family’s history of heart disease
  • Telling a parent, guardian, coach, or healthcare professional about unexplained symptoms

Healthy habits developed during adolescence can contribute to cardiovascular health later in life.

Frequently Asked Questions

Can a healthy teenager have a heart attack?

It is possible, but extremely uncommon. When a heart attack occurs in a teenager, healthcare professionals generally look for an underlying condition affecting the heart, coronary arteries, cholesterol levels, or blood clotting.

Can anxiety cause chest pain in teenagers?

Yes. Anxiety and emotional stress can cause chest discomfort in teenagers. However, chest pain should not automatically be attributed to anxiety, especially when it occurs during exercise or is accompanied by fainting or significant breathing problems.

Is chest pain after exercise serious?

It can be. Chest pain that repeatedly occurs during physical activity is considered a warning sign that should be evaluated by a healthcare professional.

Can myocarditis feel like a heart attack?

Yes. Myocarditis can cause unexplained chest pain and shortness of breath and may sometimes feel similar to a heart attack.
