What to Know About an Angina Episode

It may feel like pressure, squeezing, heaviness, burning, or tightness and can spread to an arm, shoulder, neck, jaw, back, or upper abdomen. Exertion, emotional stress, cold weather, or a heavy meal may trigger a familiar episode, but symptoms can also occur at rest.

Angina is a symptom rather than a disease by itself. It often reflects narrowing in the arteries that supply the heart, although artery spasm and other heart conditions can also reduce blood flow. Breathlessness, nausea, sweating, unusual fatigue, or light-headedness may accompany the discomfort.

A predictable pattern that settles with rest or prescribed medicine still deserves medical follow-up. A change in frequency, intensity, trigger, or recovery can signal unstable heart blood flow and needs prompt assessment.

Stop the activity, sit down, and stay as calm as possible. If you have been prescribed a fast-acting angina medicine, use it exactly as your clinician instructed. Do not use another person's medicine and do not drive yourself if emergency care may be needed.

After symptoms settle, record what you were doing, what the discomfort felt like, where it travelled, associated symptoms, and how it responded to rest or medicine. This pattern helps a clinician decide whether your treatment or testing needs adjustment.

Call local emergency services for new or severe chest discomfort, symptoms occurring at rest, discomfort that does not ease promptly with rest and your prescribed plan, or an episode that feels different from usual. Also seek emergency help for fainting, marked breathlessness, cold sweating, or chest discomfort with weakness or nausea.

Do not wait for an appointment when these warning features are present. Emergency clinicians can assess the heart rhythm and look for signs of heart muscle injury while treatment is started if needed.

Ask which symptoms should activate your emergency plan, how to use prescribed medicine during an episode, whether activity limits are needed, and which tests could clarify the cause. Bring an updated medicine list and mention any recent change in your symptom pattern.
