What is chest pain?
Chest pain is a common symptom that can indicate a wide range of conditions, some of which involve the heart. From a cardiologist’s perspective, evaluating chest pain is essential to identify whether it is caused by a heart problem or another condition. While many cases of chest discomfort are not serious, some may signal a potentially life-threatening issue such as angina or a heart attack.
What are the heart-related causes of chest pain?
Chest pain can originate from the heart when blood flow to the heart muscle is reduced or blocked.
Cardiac causes include:
- Angina: Pain or pressure caused by reduced blood flow to the heart muscle, often triggered by physical activity or stress
- Myocardial infarction (heart attack): Sudden blockage of a coronary artery, causing persistent and severe pain
- Pericarditis: Inflammation of the lining around the heart, which can cause sharp, stabbing pain
- Cardiomyopathy or heart valve problems: Conditions affecting heart function may lead to chest discomfort, particularly on exertion
Pain related to the heart is often described as pressure, tightness, heaviness, or squeezing in the centre or left side of the chest. It may radiate to the arm, neck, jaw, or back.
How can non-cardiac causes mimic heart pain?
Not all chest pain originates from the heart. Other causes may include:
- Gastrointestinal problems: Acid reflux or oesophageal spasms can produce burning or pressure in the chest
- Musculoskeletal pain: Muscle strain or inflammation of the chest wall can be sharp and localized
- Respiratory conditions: Infections, inflammation, or pulmonary embolism may present with chest discomfort
- Anxiety or panic attacks: These can cause tightness or palpitations that feel similar to cardiac pain
Careful evaluation is needed to distinguish between cardiac and non-cardiac causes.
How is chest pain assessed?
A cardiologist begins with a detailed history, focusing on the character, location, duration, and triggers of the pain. The assessment also considers risk factors such as high blood pressure, high cholesterol, diabetes, smoking, and family history of heart disease.
Investigations may include:
- Electrocardiogram (ECG): To assess heart rhythm and detect signs of injury or reduced blood flow
- Blood tests: To check for markers of heart muscle damage
- Echocardiogram: To evaluate heart structure and function
- Stress testing or cardiac imaging: To identify areas of reduced blood flow or coronary artery disease
This structured approach helps to confirm or exclude heart-related causes and guide appropriate treatment.
When is urgent assessment required?
Chest pain should be treated as potentially serious if it is sudden, severe, or accompanied by:
- Shortness of breath
- Sweating, nausea, or vomiting
- Faintness or dizziness
- Pain radiating to the arm, jaw, or back
Prompt evaluation is critical because conditions such as heart attack or acute coronary syndromes require immediate intervention.
How is cardiac chest pain managed?
Management depends on the underlying cause. Angina may be treated with medication to improve blood flow and reduce heart strain, lifestyle changes, or procedures such as angioplasty. Acute heart attacks require urgent medical treatment to restore blood flow and prevent heart damage.
Early recognition and timely cardiology assessment improve outcomes and reduce complications. Identifying the source of chest pain is the first step in ensuring effective treatment and protecting long-term heart health
