Diagnosis - Angina

People with episodes of angina (chest pains) should see their physician for review. The doctor will evaluate the person's medical history and risk factors, conduct a physical examination, and usually order a chest X-ray and an electrocardiogram (ECG). Some people will also need an exercise ECG (stress test), an echocardiogram or other tests to complete the diagnosis.

In unstable angina, the chest pain is unexpected and usually occurs while at rest. The discomfort may be more severe and prolonged than typical angina or be the first time a person has angina. Unstable angina is an acute coronary syndrome and should be treated as an emergency. People with new, worsening or persistent chest discomfort should be evaluated urgently as they are at increased risk for acute myocardial infarction (heart attack) and severe cardiac rhythm disturbances. Investigations usually involve cardiac catheterisation which may lead to coronary artery angioplasty.
