What happens if angina is not treated?

Angina is discomfort caused when the heart muscle does not receive enough oxygen-rich blood, often during exertion or emotional stress. Ongoing symptoms can limit activity and indicate narrowing in the coronary arteries. The pattern may change, with discomfort appearing more easily, lasting longer or occurring at rest.

Angina itself is not the same as a heart attack, but a new, worsening or unexpected pattern needs urgent assessment because reduced blood flow can become severe. High cholesterol, hypertension, smoking, diabetes and other factors may increase strain on the heart and should be reviewed.

Arrange medical assessment for recurring chest pain or chest tightness, especially if it is triggered by less activity than before. A clinician may perform an electrocardiogram and assess blood pressure, cholesterol, medicines and other cardiovascular risks.

Take any prescribed angina medicine exactly as directed and do not stop long-term treatment without medical advice. Treatment may include medicines that improve blood flow or reduce cardiovascular risk, alongside activity and lifestyle guidance suited to your health. Keep a record of triggers, duration and associated symptoms.

Call emergency services for chest pain or tightness that is severe, new, lasts longer than expected, occurs at rest or does not settle with your prescribed plan. Emergency help is also needed with sweating, nausea, fainting, severe breathlessness or pain spreading to the arm, jaw, back or shoulder.

Stop exertion and sit down while waiting for help. Do not drive yourself. A changing pattern is an urgent warning because symptoms cannot safely be judged by severity alone.

Is my pain consistent with stable angina, or does the pattern need urgent investigation? Which tests should I have? What should I do during an episode, and how should my blood pressure, cholesterol and other risk factors be managed?
