What should you know about variable angina?

Angina is discomfort caused when the heart muscle does not receive enough oxygen-rich blood for its needs. Symptoms may feel like pressure, squeezing, heaviness, or chest tightness and can spread to the arm, jaw, back, or shoulder. A variable pattern may occur with different levels of activity, at rest, or at changing times; that change does not make it harmless.

Risk factors can include high blood pressure, smoking, diabetes, raised cholesterol, and established heart or blood-vessel disease. A clinician may use an electrocardiogram alongside examination and other tests. Chest tightness can have non-cardiac causes too, so the pattern and associated symptoms matter.

Arrange a prompt medical review for new, changing, or unexplained chest discomfort. Record when it happens, what you were doing, how long it lasts, where it spreads, and whether breathlessness, sweating, nausea, or dizziness occurs. Take prescribed medicines exactly as directed and do not start, stop, or share heart medicines without advice.

Your clinician may review blood pressure, cholesterol, diabetes risk, smoking, activity, and other medicines. Treatment can include blood-pressure medication or statin therapy when appropriate, together with a plan for responding to symptoms.

Call emergency services for chest pressure or tightness that is severe, new, occurs at rest, lasts longer than expected, returns repeatedly, or comes with breathlessness, sweating, faintness, nausea, or pain spreading to the arm, jaw, back, or shoulder. Stop exertion and sit down while waiting. Do not drive yourself if symptoms could be a heart emergency.

Ask what pattern your symptoms suggest, which tests are needed, what to do during an episode, and which warning signs require emergency help. Ask how blood pressure, cholesterol, smoking, activity, and medicines affect your plan.
