Although chest pain can sometimes be a symptom of a heart problem, there are many other possible causes. While some of these are serious conditions, most are not harmful.

Chest pain is the second biggest cause of emergency room (ER) visits in the United States, leading to over 8 million ER visits every year. Worldwide, chest pain affects 20–40% of the general population.

In this article, learn about some possible causes of chest pain and other symptoms that can help identify them.

Various heart problems can cause pain in the chest.

1. Heart attack

Chest pain is one of the five main symptoms of a heart attack. The others are:

  • pain in the jaw, neck or back
  • lightheadedness or weakness
  • pain in the arms or shoulders
  • shortness of breath

Females particularly may also experience sudden tiredness, nausea, or vomiting.

If someone thinks they are having a heart attack, they should seek emergency medical help. The quicker a person can get to ER, the quicker treatment can begin.

Getting prompt treatment increases a person’s chances of survival and potentially reduces the severity of the damage to the heart.

2. Myocarditis

Myocarditis is when the heart becomes inflamed, resulting in symptoms that are similar to a heart attack, such as:

Myocarditis usually results from a viral infection, according to the Centers for Disease Control and Prevention (CDC).

3. Angina

Angina feels like a squeezing pain or pressure on the chest. It occurs when not enough blood is getting to the heart. A person may also feel pain in the:

  • shoulder
  • back
  • neck
  • arms
  • jaw

Angina can feel like indigestion.

It is a symptom of coronary artery disease.

4. Aortic aneurism and dissection

Aortic dissection is a tear or separation of the inner layers of the aorta, the main artery that leads from the heart. This can lead to a buildup of blood in the artery.

An aortic aneurysm refers to an enlargement in the aorta.

Both conditions can cause the aorta to rupture or burst.

Aortic dissection and a severe aortic aneurysm are emergencies and require immediate medical help.

A stable aortic aneurysm may not need emergency treatment.

5. Coronary artery dissection

Coronary artery dissection is when tearing occurs in the coronary artery wall. If the innermost layer tears, blood can seep through and build up, causing a bulge. It can lead to a heart attack.

Sudden intense pain that appears to “tear” across the chest, neck, back, or abdomen can be a symptom of coronary artery dissection.

This is a rare but serious condition. The American Heart Association (AHA) notes that experts do not know exactly why it happens, but it can affect people without the usual risk factors for heart disease.

6. Pericarditis

Pericarditis is inflammation of the sac around the heart.

It can result in:

  • severe chest pain behind the breast bone
  • a buildup of fluid around the heart
  • cardiac tamponade, when fluid presses on the heart
  • obstructive shock, when the heart cannot fill with blood effectively

Pain may be worse when a person breathes in or is lying down but improves when they sit up or lean forward.

It usually results from a viral infection, but there are many other possible causes.

7. Mitral valve prolapse

A mitral valve prolapse is when a valve in the heart is unable to close fully. In mild cases, this condition may have no obvious symptoms.

If symptoms occur, they include:

  • rapid heartbeat
  • chest discomfort
  • fatigue

8. Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy is when the heart grows too thick due to genetic factors. The thickening of the heart prevents blood from flowing from the heart properly, causing the muscle to work very hard to pump blood.

Symptoms of hypertrophic cardiomyopathy include:

  • chest pain
  • changes in heart rhythm
  • shortness of breath
  • dizziness
  • lightheadedness
  • fainting
  • swelling in the feet, ankles, legs, and abdomen

A person who notices this should seek medical advice, as it can worsen over time and lead to other complications, such as blood clots and heart failure.

Various lung problems can cause chest pain.

9. Pulmonary hypertension

Pulmonary hypertension is high blood pressure in the arteries that carry blood to the lungs. In some cases, this may result in chest pain.

It can happen for various reasons and can result in:

  • breathlessness and faintness when exercising
  • shortness of breath when bending down
  • fatigue
  • swelling due to fluid buildup

Pulmonary hypertension is not usually immediately life threatening, but it does need medical attention.

10. Pleurisy

Pleurisy is inflammation of the membrane that covers the lungs.

Symptoms include:

  • chest or shoulder pain
  • pain is worse when breathing, coughing, sneezing, or moving the trunk or chest wall
  • pain may be dull, aching, or “catching”

Without treatment, it can lead to life threatening complications.

11. Pneumonia

Lung infections such as pneumonia can cause sharp or stabbing chest pain, especially when breathing deeply or coughing.

Other symptoms of pneumonia include:

  • fever, sweating, and chills
  • coughing up phlegm, which may be green, yellow, or contain blood
  • shortness of breath
  • bluish tinge to the lips or fingetips
  • rapid, shallow breathing
  • low appetite, low energy, and fatigue
  • nausea and vomiting (in young children)
  • confusion (in older people)

A person with breathing difficulty needs immediate medical attention, as pneumonia can be life threatening.

12. Pulmonary embolism

A pulmonary embolism is when a blood clot gets trapped in an artery feeding blood to the lungs.

Common symptoms include:

  • chest pain, especially when breathing in
  • back pain
  • shortness of breath
  • coughing up blood
  • leg pain or swelling
  • sweating
  • lightheadedness, dizziness, or fainting
  • blue tinge to lips or nails, known as hypoxia

Pulmonary embolisms can be life threatening without urgent treatment.

13. COVID-19

A person with COVID-19 may experience respiratory symptoms, pain, or pressure in the chest.

A person should seek immediate medical help if they have:

  • persistent pain or pressure in the chest
  • breathing difficulty
  • blue lips or nails
  • new confusion
  • difficulty staying awake

14. Tuberculosis

Tuberculosis (TB) is a bacterial infection that usually affects the lungs.

It can cause:

  • chest pain
  • a bad cough which may produce blood or sputum
  • weight loss
  • a fever and night sweats

In the past, TB was nearly always fatal. Nowadays, antibiotics can usually treat it successfully.

15. Asthma

Asthma is a common breathing disorder characterized by inflammation in the airways, which can cause chest pain.

Other symptoms include:

  • tightness in the chest
  • shortness of breath
  • coughing
  • wheezing

What is severe asthma?

16. Collapsed lung

When air builds up in the space between the lungs and ribs, leading to a collapsed lung, also known as pneumothorax.

Some people have no symptoms, but the following may occur:

  • chest pain, which may radiate to the shoulder
  • discomfort when breathing
  • faster breathing rate
  • shortness of breath
  • swelling on one side of the chest
  • reduced breathing sounds

A punctured lung is another cause of pneumothorax.

The following conditions affect organs that play a role in digestion. Chest pain can be a symptom.

17. Pancreatitis

Pancreatitis is an inflammation of the pancreas. Acute pancreatitis usually results from gallstones. Chronic, or long-term pancreatitis stems from genetic features or high alcohol consumption.

A person may notice:

  • upper abdominal pain which may begin suddenly or slowly, be mild or severe, and last several days
  • swollen or tender abdomen
  • nausea and vomiting
  • fever
  • pain that radiates to the back

If a person notices these symptoms for the first time, they should seek medical help at once.

18. Esophageal spasms

Esophageal contraction disorders are spasms or contractions in the food pipe.

Symptoms include:

  • chest pain
  • difficulty swallowing
  • regurgitation
  • heartburn

These disorders can also cause chest pain.

19. Esophageal hypersensitivity

In a person with esophageal hypersensitivity, sensations that are not usually painful can cause severe pain.

Experts do not know exactly why this happens, but cells in the gullet may be particularly sensitive to acid. Stress may trigger symptoms in people who are susceptible.

20. Esophageal rupture

If the food pipe bursts, this can result in sudden, intense chest pain. An esophageal rupture may occur after a procedure involving the esophagus or a traumatic injury.

Other possible symptoms include:

  • retching and vomiting
  • a crackling sound on touching the chest
  • shortness of breath or rapid breathing

21. Peptic ulcers

Peptic ulcers are sores in the stomach lining.

They can cause:

  • pain in the abdomen or upper abdomen after eating
  • bloating
  • nausea
  • vomiting, possibly with blood

They do not usually cause intense pain but can result in a recurring discomfort in the chest.

22. Gastroesophageal reflux disease (GERD)

GERD refers to when the contents of the stomach move back up into the throat.

It can lead to:

  • chest pain
  • regurgitation
  • nausea and vomiting
  • difficulty swallowing or pain when swallowing
  • a cough, hoarseness, or other symptoms in the throat

Over-the-counter antacids can often relieve GERD.

27. Injured ribs

Injuries to the ribs, such as bruises, breaks, and fractures, can cause chest pain. A person may have heard a crack or felt extreme pain at the time of injury if they have a broken rib.

A person with a fractured rib may have:

  • pain or discomfort in the chest or back
  • an inability to breathe in deeply
  • unusual movement in the chest wall

What can you do if you have a broken rib?

Here are the answers to some questions people often ask about chest pain.

How do I know if chest pain is serious?

Pain that is severe or feels like it is squeezing the chest could be a sign of a heart attack. Breathing difficulty is another sign of chest pain that could be serious. People with these symptoms should seek immediate medical help.

Why am I having pain in my chest?

Chest pain can occur for many reasons, ranging from muscle strain to a heart attack. It is best to seek medical advice for any type of chest pain, as some causes can have severe consequences.

What does chest pain feel like?

This will depend on the cause. Pain that is heavy, squeezing, or radiating pain may be a sign of a heart problem. If there is reflux and difficulty swallowing, it could be due to a gastrointestinal problem. Breathing difficulty may indicate a broken rib, a heart condition, or a lung complaint.

Chest pain can happen for many reasons. Often, the other signs that occur with it will give an idea of why chest pain occurs.

However, any severe chest pain needs urgent medical attention, especially if it is radiating to the arm, back, or neck, if the heart rate changes, or if the person has trouble breathing.

Anyone with concerns about chest pain should seek medical advice to rule out life threatening causes and obtain suitable treatment.
