Understanding Chest Pain

Cardiac chest pain is typically central or left-sided pressure, heaviness, or tightness — provoked by exertion or stress, lasting 2–15 minutes, with radiation to the left arm, jaw, or neck. Non-cardiac pain is more often sharp, very brief (<5 seconds), reproduced by pressing on the chest, or worse with breathing. However, symptoms overlap substantially — the only reliable way to distinguish cardiac from non-cardiac is formal assessment with ECG, blood tests, and echocardiography. Never self-diagnose chest pain as non-cardiac without a proper evaluation.

Go to emergency immediately if chest pain is: severe, new, or worst ever; accompanied by sweating, breathlessness, or nausea; radiates to the left arm, jaw, or back; persists more than 15 minutes at rest; is associated with fainting, light-headedness, or palpitations; or occurs with any neurological symptoms. Do not drive yourself — call 108. Chew aspirin (325 mg) if not allergic while awaiting help. For heart attacks, door-to-balloon time under 90 minutes dramatically improves outcomes — every minute of delay matters.

Initial evaluation includes: 12-lead ECG (first test — detects STEMI, prior MI, ischaemic changes); high-sensitivity troponin blood test (elevated in heart attack); chest X-ray. If acute coronary syndrome is excluded, further investigation includes 2D echocardiography (wall motion, valve disease), treadmill stress test or TMT (exercise-induced ischaemia), CT coronary angiography (non-invasive coronary anatomy), and invasive coronary angiography with FFR when pre-test probability is high or non-invasive tests are positive.

If you experience sudden or severe chest pain at rest, call emergency services (108 in India) immediately — do not drive yourself. While waiting, sit in a comfortable upright position, chew one adult aspirin (325 mg) if you are not allergic and have no contraindication, and loosen any tight clothing. Note the time the pain started and any associated symptoms such as sweating, breathlessness, or nausea. Do not eat or drink anything except a small sip of water with the aspirin. If you have been prescribed sublingual nitroglycerin, take one dose as directed. Rapid action saves heart muscle — every minute of delay increases permanent damage.

Stable angina is predictable chest tightness or pressure that occurs with exertion (e.g., walking uphill, climbing stairs) and reliably resolves within 5–15 minutes of rest or sublingual nitroglycerin. The coronary artery has a fixed narrowing that limits blood flow during increased demand but the plaque is stable. A heart attack (myocardial infarction) occurs when a plaque ruptures, forming a blood clot that suddenly blocks the artery completely — causing prolonged chest pain that does not resolve with rest, often accompanied by sweating, nausea, or breathlessness. Angina indicates risk; a heart attack indicates active muscle damage requiring emergency treatment.

Yes — anxiety and panic attacks can produce chest pain that closely mimics cardiac pain. Typical features include sharp or stabbing chest discomfort, a sense of impending doom, rapid breathing or hyperventilation, tingling in the hands or around the mouth, and palpitations. The pain may shift location and is often reproducible by pressing on the chest wall. However, because the symptoms can be indistinguishable from acute coronary syndrome, especially in patients over 40 or those with cardiac risk factors, it is essential to complete a proper cardiac evaluation — including ECG and troponin — before attributing chest pain to anxiety. Never self-diagnose chest pain as anxiety without a medical assessment.

Costochondritis is inflammation of the cartilage connecting the ribs to the breastbone (sternum). It produces sharp, localised chest pain that is typically reproducible by pressing firmly on the affected rib-joint area — a feature that is absent in cardiac pain. The pain may worsen with deep breathing, coughing, or certain arm movements. Costochondritis is benign and self-limiting, usually resolving within weeks with rest, anti-inflammatory medications, and ice or heat application. However, because the chest location overlaps with cardiac pain, anyone with new chest pain — especially those over 40 or with cardiac risk factors — should undergo ECG evaluation before assuming the cause is musculoskeletal.

Not every chest pain requires an ER visit, but certain features demand immediate emergency evaluation: pain that is severe, new, or the worst you have ever experienced; pain accompanied by sweating, breathlessness, nausea, or vomiting; pain that radiates to the left arm, jaw, neck, or back; pain that persists more than 15 minutes at rest; chest pain associated with fainting, light-headedness, or palpitations; or any chest pain in a patient with known heart disease, diabetes, or multiple cardiac risk factors. For mild, brief, reproducible chest pain in a young, healthy person with no risk factors, a scheduled outpatient evaluation is appropriate. When in doubt, err on the side of caution — call 108 or proceed to the ER.
