Chest Pain and Breathlessness Assessment in London
A careful assessment can identify whether symptoms are likely to come from the heart, which tests are useful and when another cause should be considered.
Symptoms need context.
Chest discomfort may be caused by the heart, lungs, digestive system, muscles or stress. Breathlessness can relate to heart function, valves, rhythm, lungs, anaemia, fitness or several factors together. The pattern often guides the safest and most efficient investigation.
Dr Bhuva reviews when symptoms occur, their relationship to exertion, duration, associated features, medical and family history, cardiovascular risk factors and previous test results. Examination and an ECG may be followed by targeted investigation when appropriate.
Symptoms assessed
- Recurring or exertional chest discomfort
- Breathlessness during activity or when lying flat
- Reduced exercise capacity or unexpected fatigue
- Dizziness, near-fainting and blackouts
- Swelling, a heart murmur or an abnormal ECG
- Concerns after an emergency-department or GP assessment
Common conditions considered.
Coronary disease
Symptoms, risk and previous results guide whether coronary imaging or functional assessment is appropriate.
Valve disease
A murmur, breathlessness or reduced exercise tolerance may prompt echocardiography and clinical follow-up.
Heart-muscle disease
Cardiomyopathy and heart failure may require ECG, echocardiography, blood tests and sometimes cardiac MRI.
Rhythm problems
Breathlessness, chest awareness or dizziness can occur with fast, slow or irregular rhythms.
Blood pressure
Very high or poorly controlled blood pressure can contribute to symptoms and longer-term cardiovascular risk.
Non-cardiac causes
A useful cardiology opinion sometimes concludes that another specialty or primary-care pathway is more appropriate.
Chest pain and breathlessness questions.
What does a planned chest-pain assessment usually include?
A planned assessment reviews the pain pattern, exertional relationship, cardiovascular risk, examination and ECG. Further testing is selected only when it is likely to clarify the cause or change management. Sudden or severe symptoms require urgent care rather than a private appointment.
When should chest pain be treated as an emergency?
Call 999 for sudden or persistent tight or heavy chest pain, pain spreading to the arms, back, neck or jaw, or chest pain with sweating, nausea, severe breathlessness, fainting or collapse. Do not drive yourself to hospital.
How is unexplained breathlessness assessed?
Assessment considers the heart, lungs, blood count, fitness, medication and other causes. Examination and an ECG may be followed by targeted blood tests, echocardiography, rhythm monitoring, exercise testing or imaging, depending on the clinical picture.
Can breathlessness be cardiac if my resting ECG is normal?
Yes. A normal resting ECG does not exclude every cardiac cause of breathlessness. The symptom pattern, examination, heart structure and function, rhythm over time and response to exercise may provide additional information.
Evidence and review.
Urgent symptom advice follows the NHS chest-pain guidance and NHS breathlessness guidance. Planned investigation is individual and may include coronary, structural or rhythm assessment.
