What does angina mean for the heart?

It is a symptom pattern rather than a description of the heart muscle dying. However, it can signal disease in the arteries supplying the heart and deserves proper assessment.

The heart needs more oxygen when it works harder. If coronary arteries cannot increase blood flow enough, a mismatch develops between oxygen supply and demand. The result may be pressure, squeezing, heaviness, burning, or tightness rather than a sharp pain.

A predictable pattern brought on by exertion and relieved by rest differs from discomfort that begins at rest, becomes more frequent, lasts longer, or feels more intense. Clinicians use the pattern, examination, an electrocardiogram, and other appropriate tests to distinguish angina from heart attack and from non-cardiac causes of chest symptoms.

If you have been diagnosed with angina, use prescribed medicines exactly as directed and keep a record of triggers, symptom location, associated breathlessness or nausea, and how the episode ended. Bring the record and a current medicine list to your appointment.

Treatment is tailored to the cause and may include medicines that reduce the heart's workload, control blood pressure, lower cholesterol, or reduce clotting risk. Some people need imaging or a procedure to assess or restore coronary blood flow. Do not stop heart or blood pressure medicine because symptoms have improved without discussing the specific medicine with your prescriber.

Contact emergency services for sudden or severe chest pressure, discomfort occurring at rest, symptoms that persist despite rest and your prescribed plan, or a clear departure from your established pattern. Sweating, faintness, confusion, marked breathlessness, or discomfort spreading to the arm, jaw, back, or upper abdomen add to the urgency.

Wait for emergency transport rather than driving yourself. A heart attack and angina can overlap in how they feel, so a new high-risk pattern cannot be safely sorted out at home.

Clarify whether your symptom pattern fits angina, which tests are needed, what each medicine is intended to do, and how to respond to another episode. Ask how hypertension, cholesterol, diabetes, smoking, sleep, and activity relate to your own heart risk, and request clear limits for work, exercise, travel, and fasting if relevant to your routine.
