How is angina diagnosed?

The clinician will ask where the discomfort occurs, what it feels like, what triggers it, how long it lasts, whether it spreads, and what makes it ease. Exertional pressure or tightness that improves with rest can fit an angina pattern, but symptoms alone do not prove the diagnosis.

The assessment also covers smoking, blood pressure, diabetes, cholesterol, family heart history, previous cardiovascular illness, and current medicines. Examination may include the pulse, blood pressure, heart and lung sounds, and signs of circulation problems. These findings guide which tests are useful.

An ECG records the heart’s electrical activity and may identify rhythm changes or evidence of reduced blood flow, although a resting result can look normal between angina episodes. Depending on the presentation, clinicians may use blood tests, heart imaging, exercise or medicine-based stress testing, or imaging of the coronary arteries.

Before the visit, write down the timing, triggers, location, spread, and associated symptoms of each episode. Bring a medicine list and relevant family history. Keep taking prescribed treatment unless the testing team gives specific preparation instructions.

Do not wait for an outpatient test if chest discomfort is new, severe, worsening, persistent, or occurring at rest. Call emergency services if it accompanies sweating, breathlessness, nausea, faintness, or discomfort spreading to an arm, shoulder, back, neck, or jaw. Emergency teams can assess for a heart attack and begin treatment during transport.

Ask what diagnoses are being considered, what each proposed test can show, whether medicines affect preparation, and when results will be explained. Confirm what to do if symptoms return before testing is complete.
