Coronary angiography is an imaging test. A thin catheter is used in a hospital catheterisation laboratory to outline the arteries that supply the heart. It helps show whether there is narrowing and how severe it is.
Angioplasty is a treatment that may follow if a significant narrowing is found and is suitable for intervention. A balloon, and often a stent, can be used to improve blood flow in the treated segment.
Not every angiogram leads to angioplasty. Some patients are better served by medicines and lifestyle change; some need surgical discussion; some need only the diagnostic information. The decision depends on symptoms, anatomy and overall health.
Both procedures have benefits and risks. These should be explained before consent. No interventional treatment can be described as zero-risk or guaranteed. Questions about recovery, medicines and follow-up are appropriate and welcome in clinic.
Sudden severe chest pain, shortness of breath, fainting, or symptoms of a possible heart attack require immediate emergency medical attention. Please call local emergency services or go to the nearest emergency department. This website does not provide emergency care.
