How common is shortness of breath in angina?

Angina happens when the heart muscle is not receiving enough oxygen-rich blood for its workload. Climbing stairs, walking quickly, cold weather, a heavy meal or emotional strain can bring on symptoms. Some people notice pressure, squeezing or heaviness in the chest, while others mainly feel breathless, unusually tired, nauseated or uncomfortable in the jaw, back, shoulder or arm. Breathlessness on its own can arise from many heart and lung conditions as well as other causes.

Stop the activity and rest. If you have been given a medicine for angina, use it exactly as your clinician instructed. Note what you were doing when symptoms began, how they felt, and whether rest relieved them; these details can help a clinician assess a pattern. Do not drive yourself to get urgent help if symptoms feel severe or unusual.

Call emergency services for chest discomfort or breathlessness that is new, severe, worsening, occurs at rest, lasts longer than expected, or comes with sweating, faintness, nausea or a feeling of impending collapse. Seek prompt medical review for a new pattern of exertional breathlessness, even if it settles with rest.

Ask whether your symptoms fit your known angina pattern, what activity level is appropriate, and exactly when to use your prescribed medicine. Discuss any change in frequency, triggers or recovery after rest, and whether you need a written plan for urgent symptoms.
