What should you know about secondary angina?

Angina happens when the heart muscle does not receive enough oxygen-rich blood for its workload. Secondary angina can appear when another problem raises demand or reduces supply, such as uncontrolled blood pressure, anaemia, an abnormal heart rhythm, fever, or low oxygen. It may feel like pressure, squeezing, heaviness, or tightness in the chest and can spread to the arm, back, neck, jaw, or upper abdomen. Symptoms can occur with exertion or sometimes at rest.

Arrange medical assessment rather than assuming recurring chest discomfort is benign. A clinician may review your history, examine you, perform an ECG, and request blood tests or other investigations. Treatment may include controlling blood pressure, reducing strain on the heart, treating the contributing illness, and using medicines prescribed for your situation. Take prescribed medicines as directed and do not stop blood-pressure or cholesterol treatment without advice. Keep a record of triggers, duration, associated symptoms, and what relieved the discomfort.

Call emergency services for new, severe, prolonged, or worsening chest pressure or tightness, especially with breathlessness, sweating, nausea, fainting, marked weakness, or pain spreading to the arm, jaw, back, or neck. Seek urgent help if symptoms occur at rest or do not settle with the plan given by your clinician. Do not drive yourself if you may be having a heart emergency.

Ask what underlying problem may be contributing, which tests are needed, how to use prescribed symptom relief, and which activities are safe. Ask how blood pressure, cholesterol, anaemia, or another trigger will be monitored and when to return for review.
