When to Worry About Shortness of Breath With Angina

Most people with Angina notice shortness of breath because the heart muscle is not receiving enough oxygen-rich blood during exertion or emotional stress. Breathlessness may occur with chest tightness, pressure, heaviness, or discomfort, but it can sometimes be the main symptom. Stable angina often follows a familiar pattern: symptoms start during activity and improve with rest or the angina medicine prescribed for you. A change from that pattern can signal a more serious problem.

Shortness of breath can also have causes outside the heart, including a lung problem, infection, anaemia, or a medication effect. The timing, triggers, associated symptoms, and your existing heart history help a clinician decide what needs checking.

Stop the activity, sit upright, and try to stay still. Follow the personal angina plan given by your clinician, including how to use prescribed fast-acting medicine. Do not drive yourself if symptoms are severe or do not settle. If you have been told to use an emergency medicine, use it exactly as directed.

Make a note of what you were doing, how quickly the breathlessness began, whether chest discomfort was present, and how it responded to rest or prescribed treatment. This information can help your clinician assess whether your angina pattern has changed.

Call your local emergency service immediately if breathlessness is severe, begins at rest, is rapidly getting worse, or comes with chest pressure, blue or grey lips, confusion, collapse, faintness, cold sweating, marked weakness, or pain spreading beyond the chest. Treat these symptoms as an emergency even if chest pain is absent.

Arrange prompt medical review if episodes are happening more often, lasting longer, starting with less activity, waking you from sleep, or no longer improving in the usual way. Do not wait for a routine appointment if you are unsure whether the symptoms represent a change in your angina.

Ask what pattern of breathlessness is expected for your angina, which symptoms should trigger emergency help, and how to use your prescribed medicine during an episode. You can also ask whether your treatment needs review and whether another heart, lung, blood, or medication-related cause should be assessed.
