Chest Pain: When Is It an Emergency?

Why Chest Pain Should Never Be Ignored

The chest contains the heart, lungs, large blood vessels, oesophagus, muscles, ribs and nerves. Pain from any of these structures can be felt in the chest. Some causes, such as heart attack, pulmonary embolism (a clot in the lungs) and aortic dissection (a tear in the main artery), can kill within hours without treatment, and the outcome depends heavily on how quickly care begins. The cost of seeking help for a harmless cause is small; the cost of delay for a dangerous one can be a life.

Cardiac Causes of Chest Pain

Heart attack (myocardial infarction). A blocked coronary artery starves heart muscle of oxygen. The pain is typically a pressure, squeezing or heaviness in the centre or left of the chest, lasting more than a few minutes, often spreading to the arm, jaw, neck or back, with sweating, nausea, breathlessness or a feeling of doom.

Angina. Chest discomfort caused by temporary reduced blood flow to the heart, typically brought on by exertion, emotion or cold and relieved within minutes by rest or nitroglycerin. Unstable angina, which occurs at rest, is more frequent or is getting worse, is an emergency.

Pericarditis. Inflammation of the sac around the heart causes sharp chest pain that is worse on lying flat and deep breathing, and better on leaning forward.

Myocarditis. Inflammation of the heart muscle, often after a viral infection, causing chest pain, breathlessness and palpitations.

Aortic dissection. A tear in the wall of the aorta causes sudden, severe, tearing pain in the chest or between the shoulder blades. This is a surgical emergency.

Abnormal heart rhythms and heart valve problems can also cause chest discomfort, palpitations or fainting.

Lung Causes

• Pulmonary embolism: a blood clot in the lung arteries causes sudden sharp chest pain, worse on breathing in, with breathlessness, cough or coughing blood. Risk factors include recent surgery, long travel, immobility, pregnancy, hormonal therapy, cancer and previous clots.
• Pneumonia and pleurisy: infection or inflammation causes pain with deep breaths and coughing, with fever and cough.
• Pneumothorax (collapsed lung): sudden sharp pain and breathlessness, sometimes in tall, thin young people or after injury.
• Asthma and chronic lung disease: chest tightness with wheezing and cough.

Digestive Causes

• Acid reflux (GERD): burning pain behind the breastbone, worse after meals, when lying down or bending, relieved by antacids.
• Oesophageal spasm: squeezing chest pain that can mimic angina.
• Peptic ulcer, gastritis, gallstones and pancreatitis: upper abdominal pain that may be felt in the lower chest.

Musculoskeletal and Other Causes

• Costochondritis: inflammation of the cartilage joining ribs to the breastbone, causing sharp, localised, tender chest wall pain that is reproduced by pressing on the area.
• Muscle strain from exercise, coughing or lifting.
• Rib injuries and fractures.
• Shingles: a burning, band-like pain on one side of the chest, followed by a blistering rash.
• Anxiety and panic attacks: chest tightness, racing heart, sweating, tingling and fear of dying. Panic attacks can feel exactly like a heart attack, so first-time episodes should be evaluated medically.

What to Do Right Away

1. 1Call an ambulance or emergency number. Do not drive yourself and avoid walking unnecessarily.
2. 2Sit or lie in a comfortable position and keep calm. Loosen tight clothing.
3. 3Chew one regular aspirin (300 mg) if you are not allergic and have no bleeding problems or other contraindication, unless a doctor has told you not to. Do not take aspirin if you suspect aortic dissection, since you cannot tell on your own, call first and follow the dispatcher's advice.
4. 4If you have been prescribed nitroglycerin, take it as instructed. Do not use another person's medicine.
5. 5Unlock the door and ask someone to stay with you.
6. 6Be ready to give information: when the pain started, what it feels like, your medical history, medicines and allergies.
7. 7If the person collapses, is unresponsive and not breathing normally, start CPR and use an AED if available.

What Happens at the Hospital

Doctors work quickly and in a structured way:

• Triage and vital signs: pulse, blood pressure, oxygen level and temperature.
• ECG within 10 minutes: this can show a heart attack or other rhythm problems.
• Blood tests: especially troponin, a protein released from damaged heart muscle. It is often repeated after a few hours.
• Chest X-ray: looks at the lungs, heart size and large vessels.
• Additional tests as needed: echocardiogram, CT scan of the lungs (for pulmonary embolism) or aorta, blood tests for clots and infection, and stress testing or coronary angiography for suspected heart disease.
• Treatment: may include aspirin and other blood thinners, oxygen, pain relief, nitrates, medicines to protect the heart and, for heart attack, urgent procedures to open blocked arteries.

If tests show a non-cardiac cause, doctors treat that condition, for example antacids for reflux, antibiotics for pneumonia or pain relief for a muscle strain, and arrange follow-up.

Features That Make a Heart Cause Less Likely, and Their Limits

Pain that is sharp, localised to a small spot, reproduced by pressing on the chest wall, worse with a particular movement or breath, lasts only seconds, or is clearly related to a meal may be less likely to be cardiac. However, these features do not exclude a heart problem, particularly in women, older adults and people with diabetes, who often have atypical symptoms. Do not decide for yourself that pain is "only gas."

Reducing Your Risk of Dangerous Chest Pain

1. 1Do not smoke or chew tobacco.
2. 2Control blood pressure, diabetes and cholesterol with lifestyle and regular medicines.
3. 3Eat a heart-healthy diet with vegetables, fruits, whole grains, nuts and fish, and limit salt, sugar, fried food and processed meat.
4. 4Exercise regularly, with a doctor's advice if you have symptoms.
5. 5Maintain a healthy weight.
6. 6Manage stress with sleep, relaxation and support.
7. 7Limit alcohol.
8. 8Avoid sitting for long periods, and move around during long journeys to reduce clot risk.
9. 9Treat reflux if you have frequent heartburn.
10. 10Get regular check-ups after the age of 30 to 40, or earlier if you have a family history.

Chest Pain in Special Groups

Women: may describe pressure less often and instead report fatigue, nausea, back or jaw pain and breathlessness. Young adults: causes are more often musculoskeletal, viral or anxiety-related, but use of stimulants and drugs, inherited heart conditions and clotting problems can also cause serious chest pain. Older adults and people with diabetes: may have silent or atypical presentations, so even mild or unusual symptoms need a check. Pregnant women: chest pain and breathlessness can signal heart or lung problems and need urgent evaluation.
