Chest Pain

Overview

Chest pain is any pain, pressure, tightness, squeezing, burning, or discomfort felt anywhere in the chest. Because it is the best-known symptom of a heart attack, it understandably causes alarm. But the causes of chest pain are far broader than the heart alone — the lungs, digestive system, muscles and bones, and even psychological factors can all produce chest pain.

Chest pain always deserves to be taken seriously. Regardless of what is causing it, sudden and severe chest pain can be a medical emergency. At the same time, not every chest pain comes from the heart, and in many cases there turns out to be a non-dangerous explanation. The only way to tell the difference is through medical evaluation.

Knowing when chest pain is an emergency can protect both you and the people you care about. This page covers the possible causes of chest pain, what different types of pain can mean, and when to call for help immediately.

Symptoms and Types

The character, location, and accompanying features of chest pain often provide important clues about what is causing it. Being able to describe your pain accurately to your doctor can significantly speed up the diagnostic process.

Chest pain can feel different depending on its cause:

• Pressure, tightness, or heaviness. A feeling in the centre or left side of the chest as though something heavy is sitting on it, or as though it is being squeezed. This is the classic description of cardiac chest pain. The discomfort may radiate to the left arm, jaw, neck, back, or upper abdomen.
• Sharp, stabbing pain. A pointed pain that worsens when breathing in or coughing, located at a specific spot. This pattern is more typical of inflammation of the lung lining or a musculoskeletal problem. Heart attacks rarely produce this kind of pain.
• Burning sensation. A burning feeling in the centre or lower chest suggests acid reflux — stomach acid escaping into the oesophagus. Occurring after meals or worsening when lying down, and easing with antacids, are features that point toward this diagnosis. However, burning can also occur with cardiac pain, so it still warrants attention.
• Pain that worsens with touch. Pain that increases when pressing on the chest wall, or in a particular position, is generally muscular, cartilage, or bone in origin. Cardiac pain does not worsen with touch.
• Pain that worsens with breathing. Pain that sharpens with every breath points toward lung lining inflammation, a blood clot in the lung, or air in the chest cavity.

When to See a Doctor

You cannot reliably determine the cause of chest pain on your own. In the following situations, seek medical help immediately.

Call emergency services immediately if:

• You have sudden, severe chest pain that does not ease with rest
• The pain spreads to your left arm, jaw, neck, or back
• Chest pain is accompanied by cold sweating, nausea, or vomiting
• You have sudden severe shortness of breath alongside chest pain
• You have fainted or feel that you are about to faint
• Your lips or fingertips are turning blue
• Your heart is beating very fast or very irregularly alongside chest pain

Even if you suspect these symptoms might not be a heart attack, do not wait. In a heart attack, every minute counts — and delay increases the risk of permanent damage.

Schedule an urgent medical evaluation (same day if possible) if:

• You have chest pain that is new and you do not know what is causing it
• The pain has lasted more than a few minutes
• You are experiencing recurring chest pain triggered by exercise or stress that eases with rest
• Chest pain is accompanied by fever and cough
• You have known heart disease and the pain feels different from usual

Causes of Chest Pain

The causes of chest pain fall into four main categories.

Heart-Related Causes

• Heart attack. One of the heart's own arteries becomes blocked, cutting off blood supply to part of the heart muscle. The pain is typically felt as a pressure, squeezing, or aching in the centre or left side of the chest, and may radiate to the left arm, jaw, or back. Cold sweating, nausea, shortness of breath, and a profound sense of dread can accompany it. It does not ease with rest. A heart attack is a medical emergency — call emergency services immediately.
• Angina. Chest pain caused by narrowed (but not fully blocked) coronary arteries, typically triggered by exercise or stress and relieved by rest or nitroglycerin. Angina is different from a heart attack but is an important warning sign that deserves prompt evaluation.
• Pericarditis. Inflammation of the sac surrounding the heart. It produces a sharp, stabbing chest pain that tends to ease when leaning forward and worsen when lying down or breathing deeply.
• Myocarditis. Inflammation of the heart muscle itself. It can cause chest pain, palpitations, and breathlessness, and often develops after a viral illness.
• Aortic dissection. A tear in the inner wall of the aorta. It produces sudden, extremely severe, tearing pain that typically radiates to the back. This is a life-threatening emergency requiring immediate treatment.

Lung-Related Causes

• Pulmonary embolism (blood clot in the lung). A clot, usually originating in the leg, travels to the lung. It presents with sudden breathlessness and chest pain. This is a serious, life-threatening condition.
• Pneumothorax (collapsed lung). Air enters the space around the lung, causing it to collapse. The result is sudden sharp chest pain and breathlessness. It is more common in young, lean men.
• Pneumonia and pleuritis. Lung infection or inflammation of the lung lining can cause chest pain that worsens with breathing. Fever, cough, and sputum production typically accompany it.
• Asthma and COPD. Bronchospasm in these conditions can produce a sensation of chest tightness and breathlessness.

Digestive System Causes

• Heartburn and acid reflux disease. Stomach acid escaping into the oesophagus can produce burning and pressure in the chest that is sometimes mistaken for heart pain. Occurring after meals, worsening when lying down, and improving with antacids are characteristic features of reflux.
• Oesophageal spasm. Sudden cramping of the oesophagus can cause severe chest pain that closely resembles a heart attack. Pain triggered by very cold or very hot drinks is a clue to this diagnosis.
• Peptic ulcer and gastritis. Sores in the stomach or duodenum cause burning and pain in the upper abdomen that can sometimes radiate upward into the chest.
• Gallbladder disease. A gallstone attack produces severe pain in the right upper abdomen radiating to the right shoulder, which can sometimes also be felt in the chest.

Musculoskeletal Causes

• Costochondritis. Inflammation of the cartilage connecting the ribs to the breastbone. It causes chest wall pain that worsens when pressing on the affected area and when breathing deeply. It is not dangerous and responds well to treatment.
• Muscle strain. Overexertion during exercise, heavy lifting, or persistent coughing can strain the chest muscles. The pain worsens with movement and touch.
• Shingles (Herpes Zoster). A burning, stabbing pain on one side of the chest followed by a blistering rash is characteristic. The pain can begin before the rash appears, which sometimes leads to initial confusion.

Psychological Causes

• Panic attack and anxiety disorder. During a panic attack, chest pain, palpitations, breathlessness, and a sense of impending doom can all occur together, closely mimicking a heart attack. However, there is no physical danger during a panic attack — and a cardiac cause must always be ruled out before this diagnosis is accepted.

Risk Factors

Factors that increase the likelihood of chest pain being cardiac in origin include the following:

• Older age. The risk of cardiac chest pain rises markedly after 45 in men and after 55 in women.
• A previous heart attack or coronary artery disease. Any new chest pain in these individuals should be taken seriously.
• High blood pressure, diabetes, and high cholesterol. These three conditions damage the heart's blood vessels and create the conditions for a heart attack.
• Smoking. One of the most powerful risk factors for coronary artery disease.
• Obesity and physical inactivity. Both independently increase cardiovascular risk.
• Family history of early heart disease. A parent or sibling who had a heart attack before age 55 raises personal cardiac risk significantly.

Diagnosis

Finding the cause of chest pain requires a combination of tests that your doctor will choose based on the nature of your symptoms and accompanying signs.

Methods used to evaluate chest pain include the following:

• ECG (electrocardiogram). Records the heart's electrical activity. Changes indicating a heart attack, rhythm disturbance, or heart muscle damage can be detected within minutes. It is one of the first tests performed in any emergency chest pain assessment.
• Blood tests. A protein called troponin enters the bloodstream when heart muscle is damaged. Elevated troponin is one of the key indicators of a heart attack. Inflammatory markers, D-dimer (which helps detect blood clots in the lung), and other values may also be checked.
• Chest X-ray. Shows lung problems, an enlarged heart, and fluid around the lungs.
• Echocardiogram (heart ultrasound). Creates a moving image of the heart. Reveals areas of heart muscle moving poorly, valve problems, and fluid around the heart.
• CT scan. Can be used to check for blood clots in the lung (CT pulmonary angiogram), an aortic tear (CT aortogram), or the coronary arteries (coronary CT angiogram). Particularly valuable in emergency settings.
• Stress test. Evaluates how the heart behaves during exercise. Used to identify angina and assess the significance of coronary artery narrowing.
• Coronary angiography. Direct imaging of the heart's own arteries. If a narrowing or blockage is found, a stent can often be placed in the same procedure.
• Endoscopy. Used when a digestive cause is suspected, to examine the oesophagus and stomach directly.

Treatment

Treatment of chest pain depends entirely on its underlying cause. This is why getting the right diagnosis first is everything.

• Heart attack treatment. Every minute matters. Opening the blocked artery as quickly as possible saves heart muscle. Angioplasty and stenting open the artery directly. When this is not immediately available, clot-dissolving medication is used. Long-term medication — including aspirin, blood thinners, and cholesterol-lowering drugs — is started immediately after.
• Angina treatment. Nitroglycerin relieves acute episodes. Beta-blockers, calcium channel blockers, and long-acting nitrates reduce the frequency of attacks. When arterial narrowing is significant, stenting or bypass surgery may be recommended.
• Pericarditis and myocarditis treatment. Pain relievers, anti-inflammatory medication such as ibuprofen, and rest form the core of treatment. Steroids may be needed in more severe cases.
• Pulmonary embolism treatment. Blood-thinning medication (anticoagulants) is started immediately. In severe cases, clot-dissolving drugs or interventional procedures may be used.
• Reflux and digestive causes. Acid-suppressing medications (proton pump inhibitors), lifestyle changes — avoiding large meals, not lying down after eating, raising the head of the bed — and where necessary endoscopic procedures are the main approaches.
• Costochondritis and muscle pain. Pain relievers, anti-inflammatory medication, warmth, and rest are usually sufficient. This type of pain typically resolves on its own over time.
• Panic attack treatment. Breathing exercises, cognitive behavioural therapy, and where appropriate medication are effective. A cardiac cause must always be excluded first.

Prevention and Living Well

The risk of cardiac chest pain can be substantially reduced through lifestyle changes.

• Quit smoking. The single most impactful thing you can do for your heart. Within one year of stopping, the risk of a heart attack falls by half.
• Keep your blood pressure under control. Measure it regularly at home and work with your doctor to keep it within a healthy range.
• Manage cholesterol and blood sugar. Alongside medication, diet and exercise make a meaningful difference to both values.
• Exercise regularly. At least 150 minutes of moderate-intensity activity per week — such as brisk walking — is one of the most evidence-backed ways to protect the heart.
• Maintain a healthy weight. Obesity increases the risk of both cardiac and digestive causes of chest pain.
• Manage stress. Chronic stress has direct and indirect harmful effects on the heart. Meditation, exercise, and adequate sleep are among the most effective tools for managing it.

Preparing for Your Appointment

Coming prepared to your appointment helps your doctor reach a diagnosis more efficiently.

What you can do:

• Note when the pain started, how long it lasts, and how it feels (pressure, burning, sharp, etc.)
• Describe what triggers the pain or makes it better (exercise, eating, stress, position)
• Mention whether the pain spreads to another part of the body
• Note any accompanying symptoms (breathlessness, sweating, nausea, palpitations)
• Mention any chronic conditions such as heart disease, diabetes, or high blood pressure
• List all current medications
• Mention any family history of early heart disease

Questions you may wish to ask your doctor:

• What is causing my chest pain?
• Is there a heart-related problem?
• Which tests do I need?
• What should I do if the pain comes back?
• Which symptoms mean I should call emergency services?
• Can I exercise?
• Do I need medication?

Questions your doctor may ask:

• When did the pain start and how long does it last?
• How would you describe the pain — pressure, burning, or sharp?
• Does it spread anywhere else?
• Does it come on with exertion or also at rest?
• Is it accompanied by breathlessness, sweating, or nausea?
• Have you had a heart attack or heart disease before?
• Do you smoke?
• Do you have high blood pressure, diabetes, or high cholesterol?
