Chest Pain: Causes, Warning Signs, Diagnosis and When to Seek Emergency Care

Chest pain is any discomfort, pressure, tightness, burning, or ache felt anywhere between the neck and the upper abdomen. It is one of the most common reasons people seek emergency care, and for good reason: while most chest pain has a benign cause, a smaller proportion is caused by conditions such as heart attack, pulmonary embolism, or aortic dissection that can be fatal without prompt treatment.

This guide is written for anyone experiencing chest pain themselves, or supporting a family member who is. It explains how doctors think about chest pain, what the most common causes are, which features suggest a benign cause versus a dangerous one, what tests are typically used to investigate it, and — most importantly — when you should seek urgent or emergency medical care rather than trying to "wait it out".

• "Heart attacks always cause severe, crushing pain." Some heart attacks — particularly in women, older adults, and people with diabetes — present with milder discomfort, breathlessness, fatigue, or nausea rather than classic crushing pain.
• "If I can press on the area and it hurts, it can't be my heart." Reproducible pain on pressing (tenderness) does make a musculoskeletal cause more likely, but it does not fully rule out a cardiac cause, especially in people with risk factors.
• "Young, fit people don't get heart attacks." It is less common, but coronary artery disease, spontaneous coronary artery dissection, and inherited heart conditions can affect younger and physically fit people.
• "Chest pain that comes and goes isn't serious." Intermittent chest pain — particularly with exertion — can be a symptom of angina and should still be assessed.

If you are ever in doubt about whether your chest pain could be serious, treat it as an emergency. It is always appropriate to seek urgent assessment for chest pain — doctors and paramedics expect and welcome this.

• Angina — chest tightness triggered by exertion or stress, caused by reduced blood flow to the heart muscle, usually easing within minutes of rest.
• Heart attack (myocardial infarction) — sudden blockage of a coronary artery causing damage to heart muscle; pain is often severe, persistent, and accompanied by sweating, nausea, or breathlessness.
• Pericarditis — inflammation of the sac around the heart, often causing sharp pain that improves when leaning forward.
• Arrhythmia — abnormal heart rhythms can cause chest discomfort alongside palpitations or dizziness.

If you have known risk factors such as high cholesterol, high blood pressure, diabetes, smoking, or a family history of early heart disease, you can use our ASCVD Risk Calculator to estimate your 10-year cardiovascular risk, and review your cholesterol results for context.

• Musculoskeletal pain — costochondritis (inflammation of the rib cartilage) or muscle strain; typically reproducible by pressing on the chest wall or moving the torso.
• Acid reflux (GORD) — a burning sensation behind the breastbone, often after meals, spicy food, or lying flat.
• Pleuritic pain — sharp pain that worsens with deep breathing or coughing, often following a chest infection.
• Anxiety and panic attacks — chest tightness with breathlessness, tingling in the hands, and a sense of impending doom; a real physical experience that still warrants assessment if new.
• Shingles — a band-like burning pain that may precede a rash on one side of the chest.

The initial assessment usually involves a focused history (what the pain feels like, how it started, and any associated symptoms), a physical examination, and some or all of the following tests:

• ECG (electrocardiogram) — records the heart's electrical activity to look for signs of a heart attack or arrhythmia.
• Troponin blood test — measures a protein released when heart muscle is damaged; often repeated a few hours apart.
• Chest X-ray — can identify lung causes such as pneumonia or a collapsed lung. See our guide on reading an X-ray report.
• CT scan — may be used to look for a pulmonary embolism or aortic dissection. Learn more in our CT scan results guide.
• Echocardiogram — an ultrasound of the heart to assess its structure and function.

If you have already had blood tests, our blood test analysis tool can help you understand what the results may mean before you see your doctor.

Treatment depends entirely on the underlying cause. Cardiac causes may require medications (such as aspirin, nitrates, or statins), procedures such as angioplasty, or urgent hospital admission. Musculoskeletal pain is often managed with rest, gentle stretching, and simple pain relief. Reflux-related pain may respond to dietary changes and acid-suppressing medication. Anxiety-related chest tightness can improve with breathing techniques, psychological support, and treatment of the underlying anxiety disorder — but should still be properly assessed the first time it occurs.

Recovery timelines vary widely: musculoskeletal pain often settles within days to a few weeks, while recovery from a cardiac event may involve weeks of cardiac rehabilitation and long-term medication. Reducing future risk generally involves managing blood pressure, cholesterol, and blood sugar, stopping smoking, staying physically active, and attending recommended follow-up appointments. Tracking your resting heart rate and activity trends over time can help you and your care team monitor recovery.
